Problems solved by technology

[0003] However, it is not enough for a piece of protective clothing to have the function of fluorescence. For example, workers in the electric power industry will often face dangers such as arc explosions and fires. Function
[0004] Shaanxi Yuanfeng discloses a fluorescent flame-retardant multi-functional double-layer fabric and its preparation method (public number: CN105483898A). Polyester is used as the veil, and flame-retardant yarn is used as the inner yarn. Two-layer fabrics are connected together, and double-layer fluorescent flame-retardant fabrics are obtained by dyeing polyester with fluorescent colors. However, the flame-retardant protection performance of polyester fabrics is poor, and holes and melting will appear in case of fire; in order to achieve higher requirements For safety protection, high-performance fibers with permanent flame-retardant properties must be used
Hangzhou Aorong Technology discloses a double-layer arc-proof fabric (publication number: CN203913517U), the surface layer is composed of aramid 1414, acrylic, nylon and flame-retardant viscose, and the inner layer is aramid 1313 and flame-retardant Composed of viscose, this kind of fabric has excellent flame-retardant properties and anti-arc properties, but the above-mentioned flame-retardant fabrics have dyeing problems and cannot meet the requirements for fluorescence
Foreign countries also attach great importance to the research and development of fluorescent arc-proof fabrics. The General Electric Company of the United States has disclosed a three-layer composite high-visibility flame-retardant fabric (publication number: US20090029618A1). Fusion, flame retardant and poor heat insulation performance, the inner layer is made of flame retardant fabric, and the middle is PTFE waterproof and breathable membrane. While realizing fluorescent flame retardant, it also endows the fabric with functions such as waterproof and moisture permeability. It will crack and release highly toxic substances such as carbonyl fluoride and perfluoroisobutylene. In addition, the PTFE membrane also has disadvantages such as low peeling strength and relatively poor vapor permeability, which limit the application prospect of this fabric.
[0005] With the increasing safety awareness of people, the total consumption of safety protective clothing worldwide is also increasing year by year, and the performance requirements for safety clothing are also gradually increasing. To achieve higher requirements for safety protection, permanent flame retardant must be used. High-performance fibers, but the protective materials currently on the market, including aramid fiber, flame-retardant viscose, etc., cannot meet the requirements of fluorescent colors

Abstract

The invention discloses a highly visible arc protective multilayer composite fabric which at least comprises a surface fabric and an inner fabric, wherein the surface fabric and the inner fabric are adhered by a flame retardant adhesive; the surface fabric is woven from two or more than two of vinyon N, Lenzing flame retardant viscose and flame retardant cotton; the inner fabric is blended from one or two yarns of silicon nitrogen series flame retardant viscose, para-aramid as well as polysulfonamide and polyimide; and the flame retardant adhesive is flame retardant polyurethane or flame retardant EVA (Ethylene-Vinyl Acetate). According to the manner, the fabric disclosed by the invention can achieve long-term and excellent flame retardant and arc protective effects, and the fabric has theeffects of being humidity-absorbing and breathable, comfortable to wear, antibacterial and healthy.

Description

technical field [0001] The invention relates to the field of fabrics, in particular to a high-visibility arc-proof multilayer composite fabric. Background technique [0002] High-visibility fabrics are widely used in railways, traffic management, power maintenance and other industries that often need to work in low-visibility conditions such as rainy days, foggy days, and nights. For example, traffic control staff wear high-visibility clothing, which can effectively remind passing vehicles. , to avoid accidents. Due to the emphasis on the protective performance of fluorescent warnings, many countries in the world have issued standards for clothing fluorescence. [0003] However, it is not enough for a piece of protective clothing to have the function of fluorescence. For example, workers in the power industry are often faced with dangers such as arc explosion and fire. Therefore, the work clothes they wear also need to have multiple functions such as flame retardant and ant...
