Knitted sweaters boiled in water for a long time will cause partial hydrolysis of wool, which is more prone to hydrolysis of the main chain than in steam. Wool is not resistant to alkalis or oxidants. Chlorine oxides can partially destroy the scale layer, so use chloroxides The treatment can prevent the wool from shrinking, and can also improve the dyeability. In the steam or hot water, the wool can be shaped by tension and has a large shrinkage phenomenon at high temperatures.
If knitting yarn, sweaters, woolen sweaters and other materials have shrunk, they can be soaked in water with conditioner for a while, and then they can be stretched by absorbing the moisture. You can also use a steam iron to heat the sweater, or put it in a pot to steam for a while and then stretch it. Be careful not to pull the clothes too hard.
When knitting yarn, sweaters, sweaters and other materials experience shrinkage, there are several ways to restore them:

2. You can also prepare a steam iron, use it to heat the clothes and stretch the sweater while it is hot.
