Abstract

The invention relates to a fiber, and in particular relates to a bamboo leaf flavonoid mint core-sheath compound fiber. The bamboo leaf flavonoid mint core-sheath compound fiber is prepared by the following steps: treating tourmaline; treating a core layer material to form a non-woven needle-punched hemp palm fiber aerogel core layer material; treating a sheath layer material, namely, preparing first slurry from 0.1-0.3 part by weight of treated tourmaline, 0.6-0.8 part by weight ethylene glycol, 0.01-0.04 part by weight of bamboo leaf flavonoid and 0.02-0.05 part by weight of beta-cyclodextrin mint oil micro-powder, wherein the preparation method of the beta-cyclodextrin mint oil micro-powder comprises the step of mixing beta-cyclodextrin and mint oil according to the mass ratio of (8-15) to (40-65) at the temperature of 20-30 DEG C to form the beta-cyclodextrin mint oil micro-powder with morphology of a clathrate compound; carrying out an esterification reaction on phthalic acid and glycerol; after the reaction, feeding the first slurry, magnesium oxide and calcium hydroxide, and carrying out a polycondensation reaction; casting a belt and carrying out grain-sized dicing to obtain a polyester chip sheath layer material; carrying out composite melt spinning to prepare the bamboo leaf flavonoid mint core-sheath compound fiber. The bamboo leaf flavonoid mint core-sheath compound fiber has the functions of antibiosis and health protection, and is comfortable and environment-friendly.

Description

technical field [0001] The invention relates to a fiber, in particular to a bamboo leaf flavone mint skin-core composite fiber. Background technique [0002] Hemp fiber is a natural cellulose fiber with outstanding product characteristics, low production cost, and low requirements on production conditions. It can grow in tidal flats and low-lying places, and does not compete with grain and cotton for land. Compared with cotton fiber, its growth process requires less chemical fertilizers, The dependence on pesticides is low. [0003] CN101343815B (2012-7-4) discloses a silk hemp fiber mixed filling core material, the silk hemp fiber mixed filling core material body (2) is made of hemp fiber and silk mixed fiber, the silk hemp fiber mixed filling core material (3) The mass percent content of the hemp fiber is 20-60%. However, the core material still needs to be improved in terms of comfort and environmental protection, antibacterial ventilation and service life. Contents o...
