Maintenance of sweaters: The following points should be paid attention to in the maintenance and storage of cashmere: 1. Keep it clean, change and wash frequently to prevent moths from breeding. 2. When storing in the season, it must be washed, ironed, dried, sealed in a plastic bag, and placed flat in the closet. Pay attention to shading to prevent fading. It should be ventilated frequently, dust and damp, not exposed to the sun. Put anti-mildew and anti-moth tablets in the closet to prevent the cashmere products from being damp and moldy. 3. The lining of the matching outerwear should be smooth when worn inside, and hard objects such as pens, key cases, mobile phones, etc. should not be placed in the pockets to avoid local friction and pilling. Minimize friction with hard objects (such as sofa backs, armrests, tabletops) and hooks when wearing them outside. It is not easy to wear it for too long. It must be stopped or changed for about 5 days to restore the elasticity of the clothes to avoid fiber fatigue and damage. 4. If there is pilling, do not pull it forcibly. Use scissors to cut off the pompom to avoid being unable to repair due to the thread being off.
