Cashmere and its characteristics

　　Cashmere is a layer of soft wool that grows on the outer skin of the goat and covers the root of the goat's long hair. It grows when it is cold in winter and gradually falls off when it is warm in spring. Compared with wool and other fibers, it has the characteristics of slender, soft, smooth, light, warm, soft gloss and strong elasticity. It makes up for the shortcomings of thick, rough, poor elasticity and large shrinkage of wool. It is known as "fiber diamond" and "soft gold" in the world.

　　Purchase of cashmere sweater

　　The selection of cashmere sweater is mainly carried out from two aspects: appearance and hand feel.

　　1. Appearance: see whether the color is pure, soft and bright; Whether the pile size is moderate. If the pile is too large, it is easy to pilling, and if the pile is small, it has poor hand feeling; Then check whether the collar is flat, square and symmetrical; Whether the seam is neat and straight.

　　2. Hand feel: feel whether the hand feel is soft, smooth and elastic. If there is a rough and astringent feeling, it may contain other fibers, or the velvet quality is poor, as well as the lack of process treatment. Wearing and protecting cashmere has the disadvantages of fine fineness, short fiber and less strength than wool. Therefore, when wearing, pay special attention to avoid long-term friction with hard objects, coarse cloth, chemical fiber and other clothes to prevent contact with corrosive substances. Especially when wearing cashmere pants, do not pull vigorously and do strenuous exercise to avoid falling off, opening holes and pilling. It's best to wear it close to your body.

　　Washing and storage

　　Cashmere is acid resistant but not alkali resistant. Neutral detergent should be used. It is best to use special detergent for cashmere sweater. The water temperature shall be kept between 30 ℃ - 40 ℃; Soak for about 5 minutes during washing, and then gently knead and press. Do not knead and twist hard and wash with washing machine to avoid excessive pile surface, pilling or felting. After washing, squeeze it by hand or shake it with washing machine, put it into net bag, hang it in a ventilated and dry place or spread it flat and dry in the shade. Do not hang it vertically to avoid deformation. Iron it with steam iron after drying, and the iron temperature is 120 ℃ - 140 ℃, Cashmere sweater will not shrink, deform and fade after being washed according to the above methods. When collecting, you must wash, dry, iron and flatten it. When you fold it and put it into the box, the cashmere sweater will generally have slight pilling when you wear it for the first time. You can cut it gently with scissors. Do not pull it by hand to avoid damaging the fiber and causing holes. If there is a hole or thread opening, use the spare yarn to repair it at the after-sales service point of the manufacturer or shopping mall.
