Abstract

The invention provides an ES large biological fiber containing wormwood active ingredients. The ES large biological fiber is prepared by the following steps of preparing wormwood extract, preparing amodifier containing wormwood extract, preparing a skin layer material, preparing a core layer material, carrying out composite spinning and carrying out aftertreatment. The ES large biological fiber containing the wormwood active ingredients has the advantages that the antibacterial rate on escherichia coli can reach 98.4 percent, the antibacterial rate on staphylococcus aureus can reach 98.5 percent, and the antibacterial rate on candida albicans can reach 98.1 percent; the fineness of the biological fiber is 2.24-2.35 dtex, the breaking strength of the biological fiber is 3.0-3.5 cN / dtex, the elongation at break of the biological fiber is 91.6%-92.5%, and the moisture regain of the biological fiber is 0.23%-0.26%; and after 100 times of standard washing, the antibacterial rate on escherichia coli can still reach 95.4%, the antibacterial rate on staphylococcus aureus can still reach 95.5%, and the antibacterial rate on candida albicans can still reach 96.1%.

Description

technical field [0001] The invention relates to the technical field of ES fibers, in particular to an ES large biological fiber containing active ingredients of wormwood. Background technique [0002] ES fiber is a composite fiber with two-component skin-core structure, which is a high-end variety of differential fibers. The skin layer of the fiber has a low melting point and good flexibility, while the core layer has a high melting point and high strength. After ES fiber is heat-treated, a part of the cortex melts and plays a bonding role, while the rest remains in the fiber state, and has the characteristics of small thermal shrinkage. The fiber is especially suitable for producing hygienic materials, thermal insulation filling materials, filter materials and other products by hot air penetration process. [0003] With the increase of per capita disposable income and the change of parenting concepts, especially the continuous improvement of the safety awareness of infants...
