Abstract

The invention provides a preparing method of a semen cassiae composite fiber of a polyester carrier. The method includes the steps of preprocessing semen cassiae extracts, preparing a wall material, preparing a microcapsule and conducting spinning. The semen cassiae composite fiber of the polyester carrier is high in tow evenness, slippery in silk layer and good in package forming and has the antibacterial rate of 95.5-97.6% for microsporum odouins, the antibacterial rate of 93.9-94.2% for trichophyton schoenleini, the antibacterial rate of 90.8-92.1% for microsporum gypseum, the total anthraquinone wastage rate of 16.36-23.33% and the chrysophanol wastage rate of 6.38-15.79%. The semen cassiae composite fiber has the advantages of keeping the activity of the semen cassiae extracts and reducing the wastage rate and solves the charring problem in the high-temperature fusion spinning process of the semen cassiae extracts and polyester chips.

Description

technical field

[0001] The invention belongs to the technical field of textile materials, and relates to a composite material fiber, in particular to a cassia seed composite material fiber with a polyester carrier and a preparation method thereof. Background technique

[0002] Polyester fiber (POLYESTER FIBERS), that is, polyester fiber, is an important variety of synthetic fiber. It uses purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) as raw materials. Polyethylene terephthalate (PET), a fiber-forming high polymer prepared by chemical conversion or transesterification and polycondensation reactions, is a fiber made by spinning and post-processing.

[0003] The patent No. is the Chinese patent of CN102936836B, which provides a method for preparing antibacterial polyester with plant nano-silver. The method is to process the plant leaves to obtain the plant leaf extract, and dissolve or disperse the extract in deionized water to obtain...
