Rayon and polyester are different fabrics. While rayon comes from artificial fabrics, polyester comes from processed petroleum. Both are crucial in the clothing and apparel industry. However, it will be wise to know what will happen to it after washing and drying. So today, our discussion will be regarding their shrinkage (Dimensional stability).
Does Rayon and Polyester Shrink?
We will divide this article into two. In the first part, we will explain whether does rayon shrink or not. And in the second part, we will deal with polyester. Then are you ready to jump with us?
Okay, here we go!
Rayon is an inevitable part of the fashion and textile industries. It is highly adorable for summer dressing. People feel this very comfortable for being soft, lightweight, and beautifully breathable. It can efficiently copy the qualities of other natural fabrics such as linen, cotton, silk, etc. Moreover, you will find it very easy while deal with different colors and dyeing as a coloring method.
This semi-synthetic fabric comes from natural fibers though it gets modified through manufacturing and achieves specific characteristics. And as natural fibers, under certain conditions, it is susceptible to shrinking. Now, allow us to tell why in detail!
It would help best if you knew the conditions that cause rayon to shrink before you launder it. Then you can easily skip them. So in this section, we are going to illustrate the causes of shrinking and tactics to avoid them.
Yeah, it does. And it is the most common cause of shrinking. A dryer can compel rayon to shrink. It can even tear the fabric! Specifically, a dried rayon is prone to shrinkage.
Look, the fibers are sensitive to heat. So your rayon garment becomes vulnerable in the dryer. Even a lower temperature setting can cause shrinking to some extent. So it will be wise to dry your rayon by laying it flat upon a drying rack and letting it air dry.
Rayon is delicate in nature. Normally, it loses its shape at the moment of drying. Let’s say you will air-dry your rayon item. Nonetheless, you will have to follow two simple steps. These are as follows!
- Go toward the drying rack to lay your rayon stuff.
- Lay it completely flat to help it secure the same shape after drying.
Alternatively, you can go for hanging if your dryer lacks a drying rack. Please note that you have to use a hanger if you prefer hang-drying. However, the hanger should not be wire-made. The chances are very high that such a hanger will leave marks on your fabric. Therefore, the best option can be wood or plastic hangers since they feature a thicker shoulder.
Your rayon item can also shrink while washing. At the same time, you may also find a loss of shape while washing it in a washing machine. Why?
When rayon gets wet, it becomes more delicate. And partly because, during the rinse and spin cycle, your washing machine agitates which causes shrinkage.
So it would help best if you chose hand-washing or dry cleaning for your rayon garments. Usually, we use cooler water temperatures in hand-washing. So the chances of shrinkage are low here with this delicate fabric. It’s also safe for your hand as it does not burn your skin!
You must pay heed to the water temperature because wet rayon is far more delicate. Hot water compels the fibers to condense, and it results in shrinking.
Is the water temperature is hotter than 85 degrees? Then your rayon item is most likely to shrink. You may think of warm water as an alternative, but that can also cause it to shrink to some extent.
So it will be wise to avoid hot or warm water when you hand-wash the rayon. And while washing it in a washing machine, you should go for cool or cold water.
Experts recommend choosing hand-wash for all rayon garments. However, as a user, you may not only wear and wash rayon items. So the condition would be different while washing different fabrics altogether. Naturally, hand-washing won’t be suitable for all of them.
Therefore, you should ensure some precautions to prevent shrinking while washing your rayon fabrics in a washing machine. And in that case, you had better follow some steps, and these are as follows!
- Have some cool or cold water
- Apply a gentle detergent
- Choose the delicate setting
- Run a cycle
As we said above, the most recommendable method for rayon fabric is- hand-wash because of being delicate in nature. Nevertheless, you have to be cautious during this process to resist damage and shrinking. Experts recommend following the steps below!
- Have some cool water to fill your sink.
- Apply a delicate-fabric-friendly detergent. A couple of capfuls will suffice.
- Without bunching up the fabric, put it in the water.
- Employ your hands to distribute the soap evenly. It will help mix it with water properly.
- Dip the rayon to soak for around 30 minutes.
- Afterward, run water to rinse the soap out of the fabric. However, avoid wringing the soap to prevent damage.
- Get a clean, dry towel to lay your fabric flat.
- Rub it to reduce water without wringing out the excess water.
- Finally, hang up the fabric and let it air dry.
You will find a 100% Rayon fabric as the most susceptible fabric to shrink. Its fibers come from wood pulp, mainly a product of cellulose. And cellulose-made stuff is prone to shrinkage. Else, the chances of shrinkage are high when the whole fabric is manufactured of one kind of fiber.
However, all the rayon fabric is NOT 100% rayon-made. You had better check the care label first to know what percentage of rayon is there. Then what to do if the care label is missing? Well, in that case, it would help best if you treat that as a 100% rayon. This consideration will help you prevent shrinkage effectively.
Besides, you can learn the best method to wash a piece of fabric from the care label. Usually, experts suggest dry-cleaning for a 100% rayon fabric that you will find on the label. Allow us to repeat- it is because a wet rayon is even more delicate and susceptible to shrinking.
At the same time, you will see that they suggest avoiding using the dryer and hot water. And no matter if there is any suggestion or not, it would be best to avoid any heat-based washing and cleaning method for your 100% rayon fabric. Thus, you can secure a shrinking-free rayon garment.
Fibers like cotton and linen are also cellulose fibers. They can shrink up to 5%. However, you can not be exact regarding the percentage of the shrinkage of rayon. The way you wash will determine this. Maintaining the care label guideline is the only guaranteed approach to preventing shrinking.
See, to reduce the amount of shrinking, you can buy pre-shrunk cotton and linen. However, there is no pre-shrunk option for rayon. The nature of the rayon does not allow this! So it will be wise to follow the care label instructions strictly.
Your rayon garment may shrink more than once. It’s not possible to ascertain its percentage precisely. Every time you go for a wash, it tends to shrink unless you follow the proper steps of washing carefully.
Let’s say you wash your rayon item in hot water repeatedly. Then it will undoubtedly shrink more than once. And it will seriously shrink when you put it in a dryer. So no matter how busy you are, dare not to use a dryer for your rayon garment.
Yeah, you can shrink your rayon item. Sometimes it becomes necessary to shrink, nothing to wonder about. Then what is the purpose of this? Well, it aims to change the size often.
Suppose you have worked on a rayon sewing project and found that work fails to fit right at the end. Or let’s say you want your favorite rayon item decreased in size. In such cases, shrinking is a fantastic solution!
Or, perhaps you have a large piece of fabric, and its label is unknown to you. And since you are unaware, you can’t use it with certainty. In that case, you may want to ensure its type by shrinking. If it shrinks in a machine wash or dryer, it must be a piece of rayon.
You can either dry it in the dryer or wash it in the washing machine. These are the most workable ways to shrink rayon faster. However, the percentage of rayon that the fabric will impact the result. For instance, a 100% rayon item shall require less effort for shrinking.
Yet, such an attempt is risky. The level of shrinkage can be too much and ruins a fabric. So you have to be careful. And if you need to shrink to some extent, it would help best if you prioritize hand-washing the rayon piece using warm water.
Now we will show how these two methods can fulfill your need. Please move on!
Suppose the hand-wash with warm water failed to shrink enough. Then put your rayon item in the dryer. Nonetheless, you should not use the hottest temperature setting. It may damage the entire fabric!
So it will be wise to go for the low heat setting. Use the gentle cycle. You can even check it periodically during the run. It will help you get the desired outcome. Bring it out of the dryer as soon as it secures the intended shrinkage level. Then you can either air-dry by hanging or laying it flat on a surface.
Here is the second solution. You may wash your rayon fabric in the washing machine. A washing machine features a warm or hot water temperature setting. Any of the two can help you get the desired result.
However, the choice should depend on your need. If you want comparatively more shrinkage, select the hot water temperature setting. Besides, it would help if you applied a regular or mild detergent.
After taking out the rayon piece, see whether it has shrunk enough or not. If yes, get a towel to lay it flat. Then roll up the towel to soak up any excess water gently. Finally, lay it flat again to air-dry.
Do you know some users who prefer a blend of rayon and spandex to 100% rayon? Such a blend is a perfect shot for producing shirts, dresses, and pajamas. It permits your clothing to stretch a bit more! Apart from that, it makes your garment stronger. As a result, you can get a better-shaped, durable fabric.
Generally, such a combination consists of 5% spandex and 95% rayon. Interestingly, solid spandex does not tend to shrink. However, if it gets blended with rayon, it shrinks because the percentage of rayon exists herein. Although the shrinkage level will be lesser than that of 100% rayon, you have to be precautious.
Despite having shrinkage, you can fix your clothing. You can even unshrink though it is dependent on the shrinkage level. Do you want your rayon piece to get back its original size? It’s simple.
Soak it before you stretch it by hand! And the things you will require are as follows:
- A bucket or washbasin
- A towel
- Gentle detergent/baby shampoo
Now please follow the steps below!
- Have some lukewarm water to fill the bucket or washbasin. Feel free to apply a gentle detergent or baby shampoo.
- Sink your rayon fabric in the water completely.
- Then for mixing the soap and water with the fibers, massage the fabric gently.
- Let the soap and water penetrate the fabric end-to-end. So keep massaging different areas of it. It will relax your fiber and help stretch it easily!
- After finishing the massage, get your fabric out of the washbasin and rinse the soap out by using cold water.
- Let the excess water go by pressing the rayon. Do it gently instead of wringing. Otherwise, you may break the fibers.
- Now get a dry, clean towel to lay it flat.
- Let the fabric be rolled up inside the towel.
- You have to make the fabric feel damp. So squeeze out any remaining water by pressing the towel.
- It’s time to adjust the fabric, so unroll the towel to spread it out.
- Then gently keep stretching the rayon by hand to regain its original size.
- At last, have a dry towel or drying rack to lay the fabric flat and air dry.
By now, you must have secured the normal size. Dry-cleaning can help you prevent consistent shrinking. It would help best if you could ensure dry-cleaning your rayon item after each wear.
Based on its own nature, every fabric reacts to heat. Similarly, your polyester fabric will do, and you should be aware of this. If asked what are the most common methods in our modern for cleaning such item, you would reply- washer and dryer. Then the question comes whether these are safe and suitable for that sort of fabric.
In brief, we can say that a warm washing machine cycle is safe for polyester. Else, a normal dryer setting is perfectly workable for this stuff. Then how is that? Well, it deserves a detailed discussion. Please move on! In this part, we will explain its reaction in a wash, how to look after your such item, the ways to shrink it, etc.
Often people ask- how to shrink a polyester shirt. Look, shrinking a 100% polyester is tough. Yes, a high enough temperature can melt this, but please note that this durable creation can endure adverse circumstances without stretching or shrinking. Moreover, many polyester garments comprise exclusive chemical treatments that ensure extra protection against shrinkage.
Polyester fabric features long, durable yarns. It is essentially plastic. The journey of this fabric begins as a chemical reaction between an alcohol and an acid. It possesses a short life cycle as brittle shards of plastic. Afterward, it spun out into tiny threads through getting a molten plastic. Such a lab-designed fiber is stable enough to tackle any damage.
Therefore, if you can just save it from excessive heat, it will sustain for a long. Specifically, a 100% polyester garment can safely go with drying settings and normal washing. No problem at all!
Unless you take the necessary attempts for care, you will ruin your polyester fabric, even if it is a synthetic one. Though it would be challenging, you can shrink, melt, or misshape the polyester fabric by exposing it to temperatures. In fact, high heat is the best means to shrink polyester.
However, ironing may melt your polyester fabric. Instead, boiling water can be a good solution as it perfectly compels a polyester piece to constrict and shrink. And it is workable for most types of fabric. Before getting woven into cloth, fabric fibers are spun and stretched out into threads. This tension is released by high heat, and it lets the fibers snap back into their original, precise length.
Compared to many other natural fabrics, you will find polyester pretty adorable in this respect. It’s a bit tricky to shrink it. However, no worries! This guide will release your tension.
Okay, let’s see what happens if you put a polyester item in the dryer and washer. Gradually, we will cover both!
You can securely run any polyester item through the normal dryer settings. However, the fact is- a normal dryer cycle is not enough to shrink polyester stuff.
Usually, a dryer comprises multiple heat settings. Among them, it will be wise to select the lowest setting. And the temperature should not be above 100℉ in your dryer. It would help if you had a look at the manual before all. For drying clothes faster, dryers use motion and heat.
You will find several fabrics reacting to even low heat settings. However, you will need the highest heat setting to shrink 100% polyester. Else, you can do it by washing the garment in boiling water or multiple dryer cycles. You should not fear the normal dryer settings, as we said earlier. However, you may take different attempts to get the best result!
- You better go for an air-dry solution. Leave your polyester fabric for around 2 to 4 hours. It would be a cautious attempt.
- Are you worried about putting your polyester item in the dryer? Do you want to save your power bill? Then simply hang up the stuff in your shower. A few hours will suffice.
- You may prefer employing the tumble dry or cool dry setting. It will let you set a suitable heat level for your fabric.
What do we do in general? We manage time once a week and prefer big loads of laundry. Anyways, choose a method that meets your need best.
Do you want a safe way to dry your polyester fabric? Then follow the steps below!
- Before all, ensure that the temperature is not above 100℉.
- Now turn the wet polyester items inside out. You need to do it prior to placing them in your dryer.
- Employ a low heat or a normal heat cycle. However, before it ends, give a pause for a few minutes.
- Then bring out the slightly damp items.
- Finally, hang up them for an air-dry.
The cool or warm washing machine cycles cannot shrink, but a hot cycle can ensure at least a bit of shrinking. Do you want to save your power bill? Then use cool water and set your washing machine to permanent press.
And do you want to skip shrinking? Then dare not to wash your polyester item in temperatures above 230℉.
Apart from typical 100% polyester fabric, there are a number of polyester blends in the market. Remember, the latter needs more delicate care. Therefore, before throwing the polyester piece in the washer, it will be wise to check the care label first.
Grab the tips to wash your polyester fabric and get the desired result!
- Ensure that you will not allow any snagging on zippers and other sharp objects. So first of all, turn your garments inside out. Such action also helps prevent color fading.
- Go for either the warm or cold water settings on the washing machine.
- It would help best if you set your machine to permanent press. It employs slower spin cycles. This setting begets less friction rubbing on polyester items and prevents them from wrinkling.
- Use a gentle detergent.
In a wash, polyester blends shrink more than 100% polyester. Usually, this blend is a combination of polyester and other fibers such as cotton, rayon, spandex, etc. You will find some unique and helpful characteristics in it.
The externally mixed fibers feature some unique qualities. For instance, in a hot water setting, you will find cotton shrinking to a large extent. So naturally, when you blend polyester with this, the polycotton is sure to shrink more than 100% polyester!
Usually, such a blend features 35% polyester and 50/50 or 65% cotton. An interesting matter is- it breathes like cotton and dries faster than polyester. Thousands of t-shirts and bedsheets comprise polycotton.
During its first wash, typically 100% cotton shrinks massively. Afterward, it becomes able to retain its shape more or less. On the contrary, polycotton prevents shrinking under any normal settlement.
However, polycotton cannot skip shrinking while running through hot dryer settings and warm water washer settings. It does not happen with a 100% polyester fabric.
The blend of polyester can be 50/50, 65/35, 60/40, etc. However, keep in mind that it will be best to wash it in cool water. Thus, you can save the cotton from shrinking.
Polycotton shrinks far less than 100% cotton though the polyester fibers give protection to the cotton fibers.
You will discover the blend of polyester and rayon in dresses, underwear, fancy blouses, etc. It turns into a light, silky material. See, rayon needs far more delicate care while polyester does not.
Do you know the best method to protect such a garment? Well, you need to employ a gentle, cold water cycle in the washing machine. Else, you may go for a hand wash.
However, keep your polyester-rayon blend stuff away from any dryer. You can merely air dry this. And there are two ways for that. You may either lay them flat on a towel or hang them up in the shower to drip dry. Any of them will help avoid additional stretching.
Indeed, it is an ideal blend for yoga pants, bras, and athletic wear. It comes up in a superbly funny and stretchy element. In a wash, it may also shrink or takes an odd shape. Then what to do?
Rinse this blend in a cold cycle. Afterward, have a warm wash. Thus, you can save it from any damage.
Else, you may feel free to place it in your dryer. In that case, you will have to rely on a low heat setting.
Don’t you want to prevent static electricity build-up? Hopefully! So don’t let this be harsh with this blend anymore. For this, remove the clothing before the dryer cycle finishes. Or use a dryer sheet. Any of them will serve you efficiently.
Such a blend ranges from as much as 20% spandex and only 80% polyester while as little as 5% spandex to a whopping 95% polyester. The more spandex you have in the blend, the more delicate the treatment should be.
Let’s say a workout shirt label is “89% cotton 11% spandex.” Then it can endure a low-heat spin in the dryer and a warm cycle in the washing machine void of shrinking!
Else, suppose a garment comprises 20% spandex. Then you should wash it in a cold-water cycle and go for air drying.
Sometimes it becomes necessary to shrink our polyester garments. The controlled heat method can be an apt solution in this regard. Suppose your purchased shirt is a bit long and you want to make it fit. Then what to do?
Well, have a look at the care label first. Be sure whether it is a polyester blend or 100% polyester. If it is the latter one, the temperature level must be at least 140℉ to shrink. On the other hand, you would be happier with poly blend as it shrinks expectedly.
Anyways, let us tell you the ways to achieve 140℉. In this respect, you can rely on your washer and dryer. You need to ramp up the heat settings.
Here is the way! Before you run your garment through your washer on hot water settings, turn it inside out. Afterward, put it in the dryer in a high-heat setting. It will shrink your polyester garment for sure!
Apart from this, you may rely on the iron method. It will certainly compel your polyester clothing to shrink. For this-
- Dip your fabric first.
- Then keep its damp version rolled it up in a towel.
- Afterward, get an ironing board.
- Now, turn your garment inside out to lay it flat on that.
- Get a pressing cloth to cover it.
- Select the medium-low heat for your iron. (However, avoid high heat as it will melt, scorch, or stiffen your polyester garment.
- Then keep ironing gently until your garment gets dry.
Experts consider this as the most effective method to shrink a polyester item. At the same time, you will find it workable for 100% polyester fabric, no matter how challenging it is to shrink!
Let us show you another way to shrink your polyester product. You need to follow the steps below!
- Have a large pot of water and boil it.
- Put your polyester fabric in it.
- Let it be there for around 10 minutes.
- Now use tweezers or tongs to remove it from the water.
- Then remove excess water by rolling your polyester garment up in a towel.
- Finally, let the garment air dry.
Generally, it’s tough to shrink a cent percent polyester item. It comprises synthetic fibers, so there is no alternative to getting forceful. However, that doesn’t mean you should dare to shrink your XL size shirt to make it a medium one!
Moreover, hope not that merely a five-minute-ironing will do your work. Rather, take it as a trial-and-error process. There is no guarantee to shrink polyester more than a size or two.
How specifically can a polyester fabric be shrunk- is also a vital matter. Securing an exact size is not an easy job. The chances are very high that you will come up with a bit different outcome.
No matter how high levels of heat you use to shrink your polyester item, there is no permanent shrinking. You can not only shrink but unshrink this too!
Generally, a shrunk polyester fabric maintains its customized shape unless you stretch it out intentionally. The tactic to maintain its shape is simple- washing the garment in cool water and going for air dry.
And do you want to see the utmost level of shrinking? Then keep washing it in hot water. That’s it!
Dry-cleaning aims to protect the delicateness of your clothing. Here the chances of shrinkage are very low, to be more exact- rare. So you should treat this as a means of shrinking your polyester garment.
Let us tell you a bit about dry cleaning. It uses a liquid solvent aside from a giant, computerized washer machine. Such a washer comprises giant coolers. These coolers help prevent your polyester item from getting too hot.
However, it employs lesser heat and water. So most fabrics are going to shrink in this process for sure.
Indeed, dry-cleaning is an ideal technique for delicate or sensitive fabrics such as wool. However, despite being safe, you don’t need to apply this to your polyester garment. Such stuff does not need this. You will find it difficult to go in a regular wash cycle in that case.
Unshrinking polyester is not a tough job. All you need to do is- relax the polyester fibers in a distinct soak and employ pins or weights or pins to stretch it back into shape gently.
There are some steps you need to follow gradually. These are as follows!
- Get some lukewarm water plus a teaspoon or two of hair conditioner and fill up your sink.
- Put your polyester item in that. Immerse it for around 15 minutes.
- Prepare a drying station while it soaks. You will have to manage a rounded object to employ as clothespins. Also, it requires a flat surface covered by a towel.
- Now, bring out your product from the water. Without wringing it out to dry, rinse that under running water gently.
- Rub it to remove some water.
- Later on, roll up that garment in the towel until it is just damp.
- It’s time to dry. So lay flat your item. Use clothespins or weights to hold down the edges.
After getting dried, you will get your intended unshrunk polyester product.
Frequently Asked Questions
Question: Can you wash 70 polyester 30 rayon?
Answer: A blend of 70 polyester and 30 rayon turns into stable stuff. You can not only regard it for hand-wash but also machine-wash. We can exemplify Polynosic Rayon. This improved version features a high moisture resistance and allows you to wash and dry safely.
Question: Does rayon continue to shrink?
Answer: Every time you wash your rayon item, it will tend to shrink. Especially, if you do so in hot water repeatedly, you will see such a result. However, the incident of maximum shrinkage will happen if you put it in a dryer.
Question: Does rayon or cotton shrink more?
Answer: After three times of washes and drying, according to a study, polyester shrank 5/16 inches, rayon fabric shrank 2 1/2 inches, cotton shrank 1 3/16 inches, and wool shrank 3/8 inches. And the outcome says that rayon has the most shrinking tendency than others, whereas wool has the lowest.
Question: Do you need to clean polyester rayon too?
Answer: Polyester, rayon, spandex- are viscose, semi-synthetic and synthetic materials. Aside from a machine wash, you can hand wash them too.
Question: Can I wash polyester rayon and elastane?
Answer: Polyester rayon and elastane comprise polyester, nylon, spandex, acrylic, and acetate. Feel free to wash them in warm water as they won’t shrink. However, you should be aware of the hot dryer. It can wrinkle your stuff permanently. Else, they produce a significant amount of static electricity in the dryer. Therefore, it would help best if you manage a towel. Afterward, hang them for air-dry.
Question: How long does rayon take to air dry?
Answer: The rayon features different types of fabric. The drying time differs based on its type. Also, it depends on the environment. For example, the synthetics rayon takes up to 5 hours in an indoor setting, and 4 hours in the outdoor setting.

Question: Does wool shrink in the dryer?
Answer: Yes. Even if it is chemically designed to endure the washing machine, it will shrink. Why? Because the dryer uses heat and movement even in a low-heat setting that causes wool to shrink.
Question: Do polyester and viscose stretch?
Answer: Polyester and viscose is merely fiber content. So you never know whether the fabric is woven, knitted, or felted. You can curl polyester and rayon for minimal stretch. Otherwise, none of them are stretchy by themselves.
Question: How many sizes will rayon shrink?
Answer: Well, it can shrink up to two times. This fabric has the lowest elastic recovery rate.
Question: Does rayon shrink when dry cleaned?
Answer: Usually, it does not shrink at the time of getting dry cleaned. However, this semi-synthetic material has a high chance of shrinkage despite being composed of cellulose fibers.
Question: What material shrinks the most in the dryer?
Answer: The materials that shrink the most in the dryer are rayon, cotton, and linen. They are more readily than their man-made counterparts.
Question: Does polyester viscose blend shrink?
Answer: Yes, the polyester viscose blend shrinks at normal temperatures.
Question: Why is polyester quick drying?
Answer: Because of being extremely hydrophobic, polyester qualifies as quick-dry. The hydrophobic feature denotes that instead of absorbing water polyester fibers repel water.
This vast post aimed to enlighten you end-to-end. Both rayon and polyester are so popular that they deserved a detailed discussion like this. Okay, let us have the highlight of the things we have talked about here.
From this article, you specifically learned whether rayon shrinks in the dryer and during a wash, in hot water as well. Else, you know how to wash rayon without shrinking, how to hand-wash it, whether and how much a 100% rayon shrinks, the techniques to shrink rayon in the dryer and washing machine, whether rayon/spandex blend shrink, how to unshrink rayon, etc.
And in the second part, we have dwelt on several affairs such as whether and to what extent a polyester shrinks, what happens when you put it in a dryer, the method to dry polyester fabric, and what happens if you put it in the washer. Besides, we have focused on polyester blend and its shrinking possibility, polycotton, polyester-rayon, polyester-spandex, the shrinking capability of polyester, how to unshrink it, etc.
Shrinking is a crucial factor in dressing yourself. Both its doing and undoing matter to us. By now, as you know them in detail, nothing can stop you.
