A kind of MS elastic fiber and antibacterial polypropylene elastic warm-keeping knitted fabric and preparation method thereof

Abstract

The invention discloses an MS comfortable elastic fiber and antibacterial polypropylene fiber elastic warm-keeping knitted fabric which comprises an outer layer and an inner layer. The outer layer and the inner layer are woven through a double-sided knitted structure. The outer layer is of a double-loop structure formed by interweaving hydrophilic yarns and elastic yarns, and the inner layer is of a double-loop structure formed by interweaving polypropylene fibers containing antibacterial substances and elastic yarns. The knitted fabric has the advantages of having good elasticity kept for a long term, size stability, high strength, good comfort, good heat-preservation and warm-keeping effects and being not prone to elasticity loss after long-term usage and resistant to dry washing with an organic solvent. In addition, an antibacterial fiber additive is added in the fabric, so that the knitted fabric has antibacterial and bacteriostasic function. A preparation method of the knitted fabric is simple in process, and the stability is good.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to an elastic warm-keeping knitted fabric of MS elastic fiber and antibacterial polypropylene fiber and a preparation method thereof. Background technique [0002] With the development of the modern textile industry and consumers' higher and higher requirements for the comfort and aesthetics of fabrics, more and more fabrics with different styles began to appear. The knitted fabric made of ordinary polyester fiber and Lycra fiber has the advantages of casual fashion, elasticity, comfort, moisture absorption, and smooth hand feeling, and is favored by consumers. But, after people wear for a long time, find that the elasticity of Lycra (spandex) fiber disappears gradually, loses elasticity when serious, even the broken short fiber can pull out. Analyzing the reasons, one is that Lycra fiber is not resistant to repeated high-temperature setting above 190°C; the other is t...

Problems solved by technology

However, after people wear it for a long time, it is found that the elasticity of Lycra (spandex) fiber gradually disappears, and when it is severe, it loses its elasticity, and even the broken short fibers can be pulled out.

Analyzing the reasons, one is that Lycra fiber is not resistant to repeated high-temperature setting above 190°C; the other is that it is not resistant to chlorine bleaching, strong alkali and strong acid and other chemical substances;
