Cashmere yarn is a yarn refined from cashmere as a raw material through a complete spinning process and a strict quality control system.
Cashmere yarn is divided into woollen cashmere yarn, worsted cashmere yarn and semi-worsted cashmere yarn according to different spinning processes; it is divided into knitting cashmere yarn and woven cashmere yarn according to the purpose; it is divided into pure cashmere yarn according to the content of cashmere And blended cashmere yarn, where the cashmere content is more than 30% and less than 95% is cashmere blended, and the cashmere content is less than 30% is not cashmere yarn.
The production and processing of cashmere yarn has a complete technological process, and each link is very important and interlocking. Taking woollen cashmere yarn as an example, the production process is as follows:
Hairless carding → dyeing → dewatering → drying → knitting → carding → spun yarn → winding → doubling → double twisting → packaging:
Dye the combed hairless velvet in accordance with the requirements of the order → dehydration → drying → and velvet (if the order is cashmere yarn of primary color or natural color, dyeing, dehydration and drying are not necessary).
He velvet (also called Hemao) process: According to the process requirements, process the composition mixture (various fiber raw materials used in spinning) (such as opening, removing impurities, etc.) → evenly distribute the processed fibers according to the proportion of wool Mix, add proper proportion of Japanese crude oil during this process.

Carding process: use a carding machine to process the mixed material of the above and velvet (also called wadding) and pasting into a roving (also called "small top")
Spinning process: The roving (also called "small top") combed in the above carding process is drafted and twisted to form a spun yarn with a spinning frame, and then wound into a certain shape of yarn ear.
Cone and twisting process: use a winding machine to change the spun yarn into a tube, and remove the thin or thick yarn at the same time → use a doubling machine to combine and ply the single yarn → use a two-for-one twister to twist the ply yarn, And wound into yarn. According to the customer's order and subsequent knitting needs, the finished cashmere yarn is sealed and boxed. It is recommended to put moisture-proof paper on the upper and lower sides of the carton to avoid rain erosion during storage and transportation. If the cashmere yarn needs to be stored for a long time, it is recommended to put a 99RONG moisture-proof, mildew-proof and moth-proof sachet in the yarn bobbin!
