Cashmere should pay attention to the following points in maintenance and collection: keep it clean and wash it frequently to prevent mites from breeding. When storing in seasons, it must be washed, ironed, dried and sealed in a plastic bag and placed flat in the closet. Pay attention to shading to prevent fading. It should be ventilated frequently, dedusted and dehumidified, and not exposed to the sun. Anti-mold and anti-mite tablets should be placed in the closet to prevent the cashmere products from getting wet and mildewed. The inner lining of the outer garment should be smooth when worn inside, and the hard objects such as pens, key cases, mobile phones, etc. should be avoided in the pockets to avoid local friction and pilling. Minimize friction with hard objects (such as sofa backs, armrests, and table tops) and hooks when wearing them. It is not easy to wear for too long, and it must be stopped or replaced in about 5 days to restore the elasticity of the clothes to avoid damage to fiber fatigue. If there is pilling, do not pull it hard. Use a pair of scissors to cut the pompom to avoid being repaired due to off-line.
