Cotton shrinks at various rates based on fabric weight and shrinkage direction (lengthwise or crosswise). For our research, we shrunk 80% cotton/20% polyester t-shirts in both directions and determined how much they shrunk relative to their original dimensions.
If you wish to shrink your cotton clothing, consider how much 80% cotton shrinks. Yes, some clothing producers blend materials to create items with diverse attributes, such as shrink resistance or stretchability. If you want to know how much 80% cotton will shrink when washed in hot water and dried on high heat, keep reading.
What Is Shrinkage in Fabric
Shrinkage is a size reduction that can occur when the fabric is washed, dried, or iron. Shrinkage in clothing and fabrics is bad because it causes garments to shrink, making them less comfortable to wear. Most consumers don’t aware that fabric and garment shrinkage aren’t uniform.
What Does Cotton Shrinkage Mean
When 100% cotton is machine washed in hot water and tumble dried, it shrinks around 1/2 inch per yard. Some fabrics, such as cotton with elastane or spandex fibers, can actually lengthen when shrunk. These fabrics are usually woven rather than knitted, and they already have some elasticity.
3 Methods of Measuring the 80% Cotton Fabric Shrinkage
It’s critical to understand how your cloth is measured in order to avoid ordering errors. YARDS, METERS, and INCHES are used to measure textiles. You must order cloth in the size you need. A skilled tailor or seamstress can help you determine the optimal project measurement.
Method 1: Shrinkage Measure With Ruler
Use a ruler to measure a shrunken piece or a string to measure its length before and after washing. It’s preferable not to wash it just yet. Down one side, measure from end to end. Then check your cotton T-shirt, skirt, jeans, etc. dimensions.
Method 2: Online Calculator Method
Input your dimensions into a garment size calculator for sizing questions. Check out these men’s and women’s sizing charts. Each measurement is illustrated in the women’s guide.
Method 3: The Back of the Envelope
Start by determining how much your object shrunk. Take two measurements: one before and one after you’ve washed the clothes. After washing and drying, take measurements 1 and 2 from side seam to side seam. 3rd measurement: before washing but after sewing, between side seams.
How Do You Reduce Shrinkage
Avoid shrinking by not using a hot drier. The trick works with practically every washing machine. Wash your clothes before drying them. This should help reduce the chances of shrinking a lot.
You may reduce shrinking by avoiding washing cotton in hot water and drying it on low heat. If that isn’t possible, run your clothes through one cycle in the washing machine before placing them in the dryer. This relaxes fibers so they shrink less when heated.
Knits vs Wovens
Make sure you know if the cloth you’re buying is knit or woven. Knits are elastic, making them easier for beginners to sewing. They’re better for casual apparel that won’t be stressed heavily.
On the other hand, wovens look clean and professional, which is good if you want your project to look like a store-bought garment. You can tell a fabric’s type by feeling its texture. The smoother something feels, the more likely it is that it is woven.
Machine Wash vs Hand Wash
People wash their clothing by hand for many reasons, not just because they’re too good for a machine. It could just be more convenient or cost-effective. Don’t worry about washing your garments in a machine. If you wish to limit your environmental effect and clothing wear and shrinkage, hand washing may be preferable.
Cotton/Polyester Blends Shrink Differently
To begin, you must first understand how much cotton will shrink. It depends on the blend’s polyester percentage. If it’s over 20%, you should expect some shrinkage after washing. Polyester maintains the shape of clothes and makes them more resistant to wear and tear.
Brands to Buy
Buy non-preshrunk garments so you can wash them less often. You can use hot water instead of warm or cold if you prefer shirts like Abercrombie & Fitch, H&M, Express, and many other brands that shrink a lot when dried in a dryer after being washed.
How Do You Shrink an 80% Cotton Sweatshirt?
Place your item in a ziplock bag that has been sealed. Fill it halfway with warm to hot water and let it for two hours. Then drain the water, close your bag, and store it somewhere warm. Allow it to sit overnight or until there is no more moisture trapped inside.
Frequently Asked Questions And Answers
What Percentage of Cotton Will Shrink?
Cotton comes in a variety of percentages, such as 60%, 65%, or 100%. These figures show the percentage of cotton in a cloth. So, a 100% cotton shirt will be made of cotton and nothing else. Likewise, 65% polyester/35% rayon will shrink more than 60% rayon/40% polyester when laundered.
Is 80% Polyester and 20% Cotton Good?
This question has no definitive solution because it is dependent on the fabric’s intended purpose. Polyester is a robust synthetic fabric used in sportswear and outerwear, while cotton is a natural fabric used in casual clothing. The blended fabric may be good for some purposes, but before making a decision, think about how the fabric will be used.
What Percentage of Cotton Doesn’t Shrink?
A fabric’s cotton percentage affects its shrinkage. There is 100% cotton, but most natural fabrics contain polyester and spandex. As a result, some cotton fabrics will shrink more than others. Polyester doesn’t shrink, so 100% cotton woven with polyester won’t shrink much.
Conclusion
To predict how much 80% cotton clothing will shrink, consider a few things. The amount the item shrinks is determined by the fabric’s weight or thickness, as well as the weave. The type of cotton used (combed, carded, or mercerized) will also play a role. All things considered, it is safe to assume that a clothing item composed of 80% cotton will shrink between 5 and 10%.
