After cleaning the sweater, I believe that many people have encountered this problem. After washing, it is not shrinking or deforming after drying. At this time, we need to understand the material of the sweater and its shrinkage rate. Based on this, we can choose the appropriate size of the dyeing industry association expert committee. In the winter, if the sweater is worn every day, try to clean it once a week or two. If you change it after wearing it for two days, you don't have to wash it too often to avoid affecting warmth. To maintain the original version of the men's sweater, it should be cleaned according to the fiber properties of the sweater, but also pay attention to detergent and water temperature.

So what kinds of sweaters are there?

1. Mercerized, not shrinking, smooth, medium price

2. Pure wool, soft and warm, but washed and shrunk, the price is more expensive, not shrinking, feel smooth, medium price

3. Pure wool, soft and warm, but washed and shrunk, the price is more expensive

4. The static electricity of the wool plus acrylic fiber is easy to dry and itchy on the body.

5. Mao plus cashmere feels good, soft and smooth, warmer than pure wool, but expensive

The first thing to understand is the fiber properties of the sweater. Sweater fabrics include sweaters, cashmere sweaters, and wool-blend shirts. Regular manufacturers are marked with a fiber content specification on the clothes. Both wool and cashmere are protein fibres. These fibres are acid and alkali resistant. These are easy to shrink and deform. Most of the blended sweaters are blended with wool and chemical fibers. Such wool fabrics are less expensive and have a higher wear resistance than pure wool sweaters.

When washing a pure wool sweater, take a dry cleaning method in a professional regular laundry. After dry cleaning, the style and characteristics of the original clothes can be maintained. It is also a better washing method for the sweater. If you wash a pure wool sweater at home, try to use a pH neutral detergent to avoid damage to the wool fibers. The water temperature should not be too high, and it can be kept at around 35 degrees Celsius. Soak the sweater for 25 minutes, then gently squeeze the sweater by hand to squeeze the dirt off the sweater. Rinse with water three times, flatten the sweater and dry it with a wide hanger. When washing a blended sweater, the requirements for the detergent are not too high, as long as it is washed as described above.
