High-temperature resisting flame-retarding composite polysulfonamide fiber yarns and manufacturing method

Abstract

Provided are high-temperature resisting flame-retarding composite polysulfonamide fiber yarns and a manufacturing method. The manufacturing method is used for providing high-quality yarns for high-temperature resisting flame-retarding fabrics. The technical scheme is that the yarns are 16.7*2 tex yarns formed by spinning raw materials including polysulfonamide fibers 50-70%, flame-retarding mucilage glue 28-48% and conductive fibers 1-2%, wherein the conductive fibers are carbon fibers. Proportions of various raw materials are prepared reasonably, a best proportion is obtained through multiple technological optimization, related technological parameters are further controlled in the processes including opening and picking, cotton carding, drawing, roving, spinning, plying and the like according to the characteristics of the raw materials so as to enable various fibers in products to be distributed evenly, the requirements of high-temperature resistance and flame retarding are met, the yarns are detected according to the SJ / T11090-96 standard, and density of electric charge caused by friction of the fabrics manufactured by the yarns reaches to the standards of first-grade products.

Description

technical field [0001] The invention relates to a textile and a manufacturing method, in particular to a high-temperature-resistant and flame-retardant composite sulfonamide yarn and a manufacturing method, belonging to the technical field of textile products. Background technique [0002] With the development of modern economy, science and technology and the progress of social civilization, people are paying more and more attention to their personal living environment, working environment and their own healthy life span, and various functional fabrics have emerged as the times require. For example, furnace front work clothes, welding work clothes, fire-fighting work clothes and other fabrics working in high temperature working environment need to add a certain proportion of polysulfonamide high temperature resistant fiber. At present, the annual supply of high-temperature resistant fibers in the world is only tens of thousands of tons, and they are used in the production of...
