Problems solved by technology

However, it is currently difficult to achieve the above requirements by directly adding alginic acid to polyester.
[0008] Based on the problems of poor hygroscopicity, non-degradability, and high dyeing difficulty of polyester fibers in the prior art, the present disclosure aims to prepare a new type of composite fiber to overcome the above-mentioned problems of polyester fibers

Abstract

The invention relates to preparation and application of seaweed polyester composite fibers. The preparation method of the composite fibers comprises the following steps: (1) pretreatment: pretreating polyester by using calcium-containing alkali liquor; (2) adsorbing alginic acid fibers onto the fibers, wherein the treating fluid can comprise chitosan; in the step (3), curing liquid containing calcium ions is used for curing, and a cross-linking agent such as glutaraldehyde can be included in curing; in the step (4), an organic solvent is used for water absorption and drying, and drying can also be carried out in cooperation with heat drying. The composite fiber prepared by the invention has excellent mechanical property, moisture absorption property, antibacterial property and dyeability, and meanwhile, when the fiber is compounded with seaweed, no additional adhesive exists, and the fiber does not release formaldehyde. Meanwhile, the fiber can be used for preparing yarns, and the yarns can be used for preparing various fabrics.

Description

technical field [0001] The disclosure belongs to the field of textile materials, and in particular relates to a seaweed / polyester composite fiber and its preparation method and application. The preparation method of the fiber is simple, and the fiber has good dyeing performance, biocompatibility and mechanical performance. Background technique [0002] Traditional polyester fibers are prepared from chemical raw materials. Compared with natural fibers, this fiber has low cost and superior mechanical properties, but at the same time, the fiber is hygroscopic, comfortable, and environmentally friendly (not naturally degradable). Defects are also more prominent problems. Furthermore, the excellent mechanical properties of polyester fiber make it have better weaving performance and excellent wear durability of the fabric, but its chemical structure is tight, and the dyeing conditions are relatively harsh. Generally, high temperature and high pressure dyeing is required. High con...
