Why Do Clothes Shrink in the Wash?

Clothes made from cotton can be treated with shrink-resistant or durablepress finishes, which form cross-links between parallel polymer chains and help the polymers withstand the stress of manufacturing and keep them from relaxing during washing.

This technique may not preserve the fitted style of women's shirts. Air drying cools off fabric very quickly, making it less likely to shrink.

The shrinking of cotton clothes generally occurs in the drying process only. This drying process also has to have a heat source like a gas or electric dryer. This rapid drying process causes the natural fibers of the cloth to become scrunched together.
Do Cotton Shirts Shrink? Does % cotton shrink? Most natural fabrics shrink to some degree for two reasons: fibre shrinkage – the natural response of plant fibres to heat – and fabric shrinkage, the consequence of tension applied to yarn and fabric during manufacture.
Feb 02,  · Clothes dryers shrink cotton through the use of heat. Hanging cotton fabric outside to shrink it will not be successful, because the temperature is not high enough to cause shrinkage%(25).
Cotton is known for being prone to shrinking, but why do cotton clothes shrink in the wash? And why do clothes shrink at all? Here's a helpful guide to why some clothes shrink.

At Proper Cloth, we test all of our dress shirt fabrics to ensure that they meet this criteria.

High shrinkage fabrics can include some of the chambrays, oxford cloths and fine printed fabrics. In some cases, you may find that rather than shrinking, your shirt actually became looser around the chest, midsection and around the biceps.

This is a result of a shirt being stretched out. First the shirt is washed in water. Secondly it is put through a spin cycle to wring most of the water out of the garment. And finally, the shirt is put on some sort of rig or press where the remaining water is then steamed out, resulting in a wrinkle free and dry shirt.

The problem occurs when a cleaner pulls the shirts onto the press such that the fabric is under tension in the width direction. This tension stretches the shirt out in the width direction, and then when the shirt is steamed dry the stretch is effectively locked into the shirt. This can result in the midsection width being 0. Accounting for shrinkage is a tricky mix of art, science and legacy systems. How much will a dress shirt shrink? Of course there are a number of caveats to this rule that should also be considered: Put the garment in the dryer.

Run the dryer on medium heat until the garment's dry [source: Shrinking Wool Clothes ]. Wash the polyester garment in cold water.

Run the dryer on high heat until the garment's dry [source: Shrinking Polyester Clothes ]. Soak the garment in the hot water. Be sure the water covers the entire garment. Transfer the garment to the washing machine. Use insulated gloves or a long stick to avoid burning yourself.

The amount that clothes stretch or shrink depends upon the fabric's fiber content, the type of weave used, and the construction methods of the garment at the factory. Commercial fabric is made of materials that are woven or knitted together by a machine. Clothes made from cotton can be treated with shrink-resistant or durablepress finishes, which form cross-links between parallel polymer chains and help the polymers withstand the stress of manufacturing and keep them from relaxing during washing.
