Problems solved by technology

Seaweed fiber technology has become increasingly mature in the textile industry. How to dissolve sodium alginate to form spinning viscous solution and prepare spinning stock solution has become stable, but the price and people's awareness have not made seaweed fiber popularize. At present, the market share is not high, so there are not many yarn fa

Abstract

The invention provides a preparing process of an alginate fiber fleece type fabric. The process includes the following steps of A, conducting jet spinning on a sodium alginate solution to obtain alginate fiber yarn; B, conducting weft knitting and weaving on 20 wt% of bottom yarn and 80 wt% of surface yarn, wherein the bottom yarn is polyester filament yarn, and the surface yarn is prepared by blending alginate fiber yarn and modified polyester filament yarn; C, sequentially conducting unwinding, grey cloth carding and hemming on the fabric obtained in the step B, and then dyeing the hemmed fabric through positive ion red 3R; D, sequentially conducting washing, dewatering, drying, carding and ball rolling on the fabric obtained in the step C to obtain the alginate fiber fleece type fabric.In the preparing process of the alginate fiber fleece type fabric, the berber fleece fabric is obtained by blending the polyester filament yarn and the alginate fiber yarn, and the alginate fiber fleece type fabric is good in dyeing effect and high in color fastness by selecting specific dyes.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a preparation process of a seaweed fiber fleece fabric. Background technique [0002] In the cold winter, keeping warm is an eternal topic in the cold winter, and various home textile products made of lamb velvet fabric are a very good choice. Lamb velvet fabrics have been on the market for many years, but most of the improvements and updates in terms of hand feel, pattern or composite technology have greatly failed to meet the needs of customers. [0003] Seaweed fiber is a kind of man-made fiber, which is favored by people for its natural, environmental protection, and easy degradation characteristics. It also has functions such as far infrared, negative ions, and flame retardancy. It should make full use of renewable resources and save non-renewable petroleum resources. One must have the consciousness and consciousness that one should have. Seaweed fiber technology has beco...
