Polysulfonamide inflaming-retarding comfortable elastic knitted plus material and preparation method thereof

Abstract

The invention discloses a preparation method of a polysulfonamide inflaming-retarding comfortable elastic knitted plus material. The preparation method comprises the following steps of (1) preparation of functional inflaming-retarding yarn: adopting covering yarn of which a polyamide fiber is a yarn core externally wrapped by polysulfonamide fiber as first yarn; carrying out cabling on a vinyl chloride-acrylonitrile copolymer fiber and a polytetrafluoroethylene fiber to obtain second yarn; using cationic modified polyester low stretch yarn as third yarn; (2) weaving: weaving the treated first yarn, second yarn and third yarn by adopting a knitting process into base cloth; (3) dyeing: carrying out dyeing on the base cloth by adopting cationic dye and active dye; (4) post treatment: subjecting the dyed base cloth to dehydration, oven-drying and setting treatment, so as to obtain the polysulfonamide inflaming-retarding comfortable elastic knitted plus material. The polysulfonamide inflaming-retarding comfortable elastic knitted plus material prepared by the preparation method is obvious in the superposition functions of fire resistance, comfortableness and elasticity, good in air permeability, comfortable to wear, excellent in color fastness performance, high in environmental friendliness and further simple in preparation process, and has a favorable market prospect.

Description

technical field [0001] The invention belongs to the technical field of knitted fabric production, and in particular relates to a sulfonamide flame-retardant comfortable elastic knitted fabric and a preparation method thereof. Background technique [0002] With the continuous progress and development of society, while the social wealth is increasing, the danger of fire is also increasing, and the danger of fire is also increasing. With the improvement of people's living standards and the enhancement of people-oriented security awareness, people pay more and more attention to fire-resistant textiles and flame-retardant properties. In the past, cotton fiber clothes were the main variety. Although cotton fiber is soft in texture, has good air permeability and is comfortable to wear, the variety is very single. In recent years, the variety of chemical fiber clothing has increased, which basically meets people's diverse needs for clothing, but it is inherently highly flammable an...

Problems solved by technology

At present, polysulfone fiber has been used in the field of textile fabrics to solve the problems of non-washable, weak adhesion and stiff fabrics in existing flame-retardant fabrics. For example, patent CN103194825A discloses a seaweed fiber, wool The blended yarn, fabric and production process of sulfonamide fiber, the fabric woven by the three blended yarns has good flame retardancy, wearability and comfort; patent CN103352293A discloses a flame-retardant and fire-resistant fabric, processed Technology and its fabric, the warp yarn is blended with flame-retardant acrylic fiber, flame-retardant viscose, fine denier polyester, and aramid 1313 fibers, and the weft yarn is blended with seaweed fiber, polyphenylene sulfide, polysulfone fiber, and phenolic fiber. The tops are blended, and then processed by weaving and post-processing; and the patent CN105581409A discloses a high-comfort protective clothing fabric, protective clothing and its preparation method, which consists of an outer layer, a waterproof breathable layer and a heat-insulating comfortable layer. The outer layer is made of sulfonamide fiber
