Environment-friendly high-resilience flame-retardant composite shell fabric

Abstract

The invention relates to environment-friendly high-resilience flame-retardant composite shell fabric, and belongs to the technical field of flame-retardant functional composite shell fabric. The environment-friendly high-resilience flame-retardant composite shell fabric disclosed by the invention is consists of a flame-retardant shell fabric layer, a flame-retardant intermediate layer and a bottomcloth layer; the flame-retardant intermediate layer is prepared from one selected from loose needle-punched cotton and compact non-glue cotton, wherein the loose needle-punched cotton is prepared bymixing one or more selected from flame-retardant polyester-fiber hollow staple fiber, flame-retardant polyester-fiber staple fiber, non-flame-retardant polyester-fiber hollow staple fiber and non-flame-retardant polyester-fiber staple fiber in certain proportion; the compact non-glue cotton is prepared by mixing one or more selected from flame-retardant polyester-fiber hollow staple fiber, flame-retardant polyester-fiber staple fiber, non-flame-retardant polyester-fiber hollow staple fiber and non-flame-retardant polyester-fiber staple fiber with low-melting point polyester staple fiber in certain proportion; and the bottom cloth layer is composed of non-flame-retardant polyester-fiber knitted mesh cloth by performing flame bonding. The environment-friendly high-resilience flame-retardantcomposite shell fabric is simple in production processes, ordinary in materials, low in cost, environmentally friendly, high in resilience, good in flame retardancy and wide in range of usage.

Description

technical field [0001] The invention relates to an environment-friendly high-resilience flame-retardant composite fabric, which belongs to the technical field of flame-retardant functional composite fabrics. Background technique [0002] Due to the extensive use of flammable and combustible materials in public places, fires continue to occur, causing mass deaths and injuries, and causing great losses to people's lives and property safety. my country's new "Fire Law" was promulgated and implemented. The Ministry of Public Security and other ministries and commissions have issued a series of fire regulations in order to improve the fire safety of public places. National flame retardant standards and industry flame retardant standards have also been formulated and promulgated. The demand for flame-retardant and flame-retardant materials is increasing day by day. [0003] According to fire safety, cars, trains (high-speed rail), airplanes, ships, seats, mattresses, etc. require ...

AI Technical Summary

Problems solved by technology

However, the flame retardancy of these composite fabrics is poor. Even after increasing the amount of flame retardant, the oxygen index is difficult to reach 28%, which cannot meet the oxygen index ≥ The regulation of 28.0% cannot meet the requirements of GB8624-2012 "Classification of Combustion Performance of Building Materials and Products" and GB20286-2006 "Requirements and Marking of Combustion Performance of Flame-Retardant Products and Components in Public Places"

The environmental protection of the composite fabric obtained by adding flame retardant post-treatment is also worrying. When it is used in the seat cover of the car, the flame retardant, glue, hot melt adhesive and other substances adsorbed on the surface of the fabric are under the condition of the air conditioner heating up. It will overflow slowly, or slowly decompose and overflow, making it difficult for people to accept the smell, even toxic smell, directly affecting people's health

[0004] In the prior art, many technical researches and developments have been carried out to solve the flame-retardant problem of flame-retardant composite fabrics, such as using flame-retardant polyester fiber mixed with flame-retardant acrylic fiber and non-flame-retardant acrylic fiber; flame-retardant polyester fiber and Flame-retardant vinylon fiber and non-flame-retardant vinylon fiber are mixed; flame-retardant polyester fiber and spandex are mixed to produce flame-retardant fabrics and flame-retardant linings; flame-retardant powder and polyester are blended and spun into flame-retardant fabrics; flame-retardant fabrics and Compressed needle-punched cotton composites are prepared into flame-retardant composite fabrics, but their technical solutions are still unsatisfactory

The specific defects are as follows: 1. Some of these two or more substances with different properties are mixed to form a support or candle effect due to different combustion characteristics, and their flame retardancy decreases or even has no flame retardancy; 2. The flame retardant powder and polyester co- Flame-retardant fabrics woven with blended silk have a large difference in molecular weight and incompatibility after dyeing, and the flame retardancy decreases or even has no flame retardancy; 3. The use of compacted needle-punched cotton makes the composite fabric less resilient; 4. Production with excessive phosphorus content Increased difficulty; 5. Complex production process, lengthy process, high product cost, and poor environmental protection, etc.
