Wool opening and mixing technology in cashmere carding process

Abstract

A wool opening and mixing technology in a cashmere carding process comprises the following steps of S1, uniformly laying up water-washed cashmere with 8-10 centimeters for every layer, uniformly spraying oil-water mixed liquid of 0.07-0.08% on every layer for 10-15 minutes; S2, performing muffled storage on the moisturized water-washed cashmere for 12-24 hours in summer or 12-48 hours in winter; S3, performing opening treatment on the muffled water-washed cashmere through an opening machine to open the cashmere into a fluffy state, feeding the cashmere at a feeding quantity of 200-300 kilograms per hour and a thickness not thicker than 6-10 centimeters; S4, detecting the opened water-washed cashmere and remoisturizing the water-washed cashmere with a machinery moisturizing rate of 24-28%, and counting the water feeding amount during the remoisturizing process. According to the wool opening and mixing technology in the cashmere carding process, by adding mixing oil, the static friction coefficient as well as the dynamic friction coefficient among fiber can be adjusted, the friction force between the fiber and guide rollers can be reduced and static electricity caused by friction during the carding process can be avoided and eliminated, so the wool fiber can smoothly pass through a carding device to avoid wool loosening, winding, fiber breakage and the like.

Description

technical field [0001] The invention relates to a cashmere opening and wool (velvet) process, in particular to a cashmere opening and wool process in the carding process. Background technique [0002] The current cashmere carding production process: washed cashmere→opening and wool→pre-carding→carding→no plush. [0003] In the production of velvet and spinning, one of the processes is the wool oiling process, which is to add oil-water mixture to the fluff, and let it sit for a certain period of time so that the fluff can fully nourish and absorb the oil-water liquid, and then go through the wool blending machine. Loose handle. Opening and wool are the preparatory processes before spinning. There is also the same process in the carding production, but water is always added in the carding and wool oiling process, and there is no other substance. It just supplements the moisture regain on the machine, which has a weak protective effect on the fibers. Cashmere The damage to t...

Problems solved by technology

[0008] Generally speaking, for domestic cashmere, the fueling rate is generally controlled at 2-4‰. If it is lower than this range, it will not be able to add and blend crude oil. If it is higher than this range, one is the waste of blending crude oil, and the other is If too much crude oil is added, car paste will occur during production, which will affect production
