Abstract

The invention discloses a kapok fiber pretreatment auxiliary agent and a kapok fiber pretreatment method. The kapok fiber pretreatment auxiliary agent comprises the following ingredients by weight: 2-8 parts of PEG 2000-8000; 5-15 parts of cross-linking agent; 1-5 parts of castor oil; 5-10 parts of cation polyacrylamide; 5-10 parts of antistatic agent; 50-80 parts of water. The kapok fiber pretreatment auxiliary agent is sprinkled on the kapok fiber, and is placed at room temperature for 6-24 hours, and the kapok fiber pretreatment method is completed. After the kapok fiber pretreatment is carried out by the kapok fiber pretreatment auxiliary agent of the present invention, the strip weight unevenness decreases by 18-25%, the hairiness index decreases by 55-65%, the single thread strength increased by 20-25%, the spun yarn twisting efficiency increases by 10-15%, and the roll banding case obviously improves.

Description

technical field [0001] The invention relates to a fiber pretreatment auxiliary agent and a fiber pretreatment method, in particular to a kapok fiber pretreatment auxiliary agent and a kapok fiber pretreatment method. Background technique [0002] Kapok fiber is the thinnest, lightest, highest hollow and warmest fiber material among natural ecological fibers. It has the characteristics of smoothness, antibacterial, anti-moth, anti-mildew, soft, not easy to tangle, impermeable, non-heat-conducting, ecological, warm, and strong hygroscopicity. It can be widely used in knitted underwear, fleece, sweaters, and woven casual outerwear. , bedding, hosiery and other fields. [0003] The fineness of kapok fiber is only 1 / 2 of that of cotton fiber, but the hollow rate reaches more than 86%, which is 2-3 times that of ordinary cotton fiber. The length of kapok fiber is 8-34mm, the diameter of the middle fiber is 18-45μm, the average is 30-36μm, the wall thickness is 0.5-2μm, the fiber...
