Hemp fabric craft design composite fabric information

1. Raw material pre-treatment Hemp hemp has high colloid content, thick and hard fibers, and poor cohesion. Softener and a certain amount of moisture should be added before use, and cured for 24 hours under high temperature and high humidity conditions to maintain the moisture regain of hemp hemp. Around 12%. It is then combed to separate the strands, impurities, short lint, etc. from the fibers. For the pretreatment of yak down, 0.5%-3% silicon solution is added for humidification treatment to maintain the moisture regain at about 12%. Tencel and multi-spun fibers do not require special treatment and can be used directly after entering the factory.
　2. According to the different characteristics of each fiber, two mixing options can be used for raw material mixing: (1) Hemp and velvet, Tencel and multi-spun fibers are mixed separately during cleaning (a multi-silo mixing system is required in the cleaning process) . (2) After the blowing and carding process, the two kinds of raw sliver are mixed in the drawing process. In order to make the mixing uniform, the purchasing channel mixing must be used.
