Knitwear is short and long.

1. When washing the sweater, let it hang vertically, but not too heavy to avoid deformation. Draw down the elongated fiber in a wet state. Splice shirts and sew the bottom half of the shirt on the hem.

2. Pour warm water into the basin, drop a small amount of household ammonia water, then soak the sweater, and the soap left on the wool will melt. Gently stretch the narrowed part with both hands at the same time, and then rinse it to dryness. When it's half dry again, pull it open by hand first, and then iron it with an iron.

3. Mix the conditioner with water according to the ratio of 1: 3, soak the sweater in it for about 10 minutes, take it out, spread it on a big bath towel to absorb water, and then gently stretch the sweater. Because the ingredients in the conditioner can soften the tight knitting knots in the sweater and let the sweater relax naturally.

4. The sweater fiber is heated with a steam iron, and then stretched with both hands while it is hot. It needs to be reminded here that due to the limited heating area of the steam iron, in order to ensure uniform fiber stretching, sweaters are stretched locally, sectionally, sectionally and by heating.
