Abstract

The invention relates to fibers, in particular to tourmaline-containing sheath-core composite fibers. The tourmaline-containing sheath-core composite fibers are prepared through the following steps: (1) tourmaline processing; (2) core layer material processing, that is, bast fibers and palm fibers after degumming processing are combed and cut into short bast fibers and short palm fibers, the short bast fibers and the short palm fibers are then soaked in a mixed manner in a lignocellulose aerogel solution for 15 to 20 minutes according to a formula, the short bast fibers and the short palm fibers after the mixed soaking are then taken out for draining, the short bast fibers and the short palm fibers after the draining are sent to an opener for opening and mixing, the short bast fibers and the short palm fibers after the opening and mixing pass through airflows and are arranged through a roller groove to form meshed semi-products with S-shaped section structures, and the meshed semi-products go through spunlace to form non-woven needled bast-palm fiber aerogel core layer materials; (3) sheath layer material processing, that is, a first pulp is prepared from processed tourmalines and ethylene glycol, phthalic acid and glycerol are used for esterification reaction, the first pulp, magnesium oxide and calcium hydroxide are added after the reaction for condensation polymerization, and polyester chip sheath layer materials are obtained through strip casting and sized dicing; (4) composite melt spinning for obtaining of the tourmaline-containing sheath-core composite fibers. The tourmaline-containing sheath-core composite fibers provided by the invention achieve the antibacterial and healthcare effects, high degree of comfort, as well as environment friendliness.

Description

technical field [0001] The invention relates to a fiber, in particular to a sheath-core composite fiber containing tourmaline. 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 is made of hemp fiber and silk mixed fiber, the silk hemp fiber mixed filling hemp fiber in the core material The mass percent content 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 of the inv...
