You can put the washed cashmere sweater into a cloth bag, put it in a washing machine for dehydration, smooth it, wet it with a towel, and iron it with a steam iron at 120℃- 140℃ to the original size or fit size. The iron can't directly contact the cashmere sweater, and then flatten it to dry.
Cashmere sweaters should not be washed by washing machine. Washing cashmere products with washing machine will make cashmere products feel felted. So it is best to dry-clean or hand-wash.

Maintenance of cashmere sweater:
1. Cashmere sweaters must be washed, dried, folded, bagged and laid flat when stored in season, and cannot be hung to avoid hanging deformation. Don't put it in the same bag with other products, and store it in a dark, ventilated and dry place. Pay attention to moth prevention when storing. It is forbidden for mothproof agent to directly contact cashmere sweater.
2. When you wear it inside, the matching coat lining should be smooth and hard objects such as pens, key bags and mobile phones. Avoid in the pocket to avoid local friction and pilling. When wearing outdoors, try to reduce the friction with hard objects (such as sofa backrest, armrest and desktop) and hooks.
