Clothes shrink in the wash due to the natural crinkled state of textile fibers, which can be straightened and aligned during manufacturing, but may return to their original shape when exposed to water and heat. Understanding the science of textile fibers can help prevent shrinkage and potentially rescue garments after a laundry accident. The article explains that common textile fibers, such as cotton and linen, are made from plants and have irregular and crinkled shapes that can cause shrinkage. By knowing how textiles are made, individuals can take steps to prevent shrinkage and care for their clothes properly.
