Embodiment 1

[0017] Embodiment 1, a fire-fighting protective clothing fabric, comprising an outer layer, a waterproof breathable layer and a comfortable heat-insulating layer, the comfortable heat-insulating layer is a velvet fabric, and the velvet fabric is a double-faced velvet fabric, double-faced velvet and Compared with single face fleece, it can store more air and improve the overall thermal insulation performance of the fabric. The double-sided velvet fabric is made of double-sided terry gray fabric after brushing, brushing, shearing, and shaping. The double-sided knitted velvet fabric has a softer feel. As the inner fabric of protective clothing, it is skin-friendly and comfortable; the double-sided terry gray fabric is made of The outer layer terry yarn, the inner layer terry yarn and the ground yarn are woven together according to parameters on the terry machine. The outer pile yarn constitutes the outer suede layer of the comfortable heat insulation layer connected with the wate...

Embodiment 2

[0018] Embodiment 2, according to the fire-fighting protective clothing fabric described in Embodiment 1, the base yarn is made of flame-retardant polyester filaments. Flame-retardant polyester has excellent physical and mechanical properties. It is woven into loops as the bottom yarn to ensure that the entire fleece fabric has high strength and stretchability, and ensures that the fabric does not deform when worn; and the melting point of flame-retardant polyester is low, which can be achieved by using existing shaping equipment. Shaping ensures that fleece fabrics have excellent dimensional stability and small washing shrinkage; however, flame-retardant polyester has the problem of melting and dripping, and contact with the skin after melting will cause skin burns.

Embodiment 3

[0019] Embodiment 3, according to the fire-fighting protective clothing fabric described in Embodiment 1, the outer loop yarn is polyimide yarn. In order to eliminate dripping on the cloth surface, the outer suede layer is made of polyimide yarn. When the polyimide yarn is weaving the gray cloth, a part of the polyimide yarn and the flame-retardant polyester filament are woven into loops at the same time, and the other part forms an elongated loop on the surface of the fabric. The settling arc is then brushed, sheared, and shaped to form the fluff on the surface of the inner fabric, which wraps the flame-retardant polyester filaments. The polyimide has no melting drop and small carbonization, which can eliminate the melting drop of the cloth surface.

Abstract

The invention relates to a fire-fighting protective clothing fabric. The fabric comprises an outer layer, a waterproof breathable layer and a comfortable heat insulation layer, wherein the comfortableheat insulation layer is a velvet fabric, the velvet fabric is a double-sided velvet fabric formed by napping and shaping of double-sided terry gray fabric, and the double-sided terry gray fabric isformed by knitting outer layer terry yarn, inner layer terry yarn and bottom yarn together on a terry knitting machine according to parameters; the outer layer loop yarn forms an outer layer velvet surface layer of the comfortable heat insulation layer, and the inner layer loop yarn forms an inner layer velvet surface layer of the comfortable heat insulation layer. Clothing made of the fabric haspermanent flame retardancy, and the protective clothing can be used repeatedly without degradation of flame retardancy.

Description

technical field [0001] The invention relates to the field of fabrics, in particular to a fabric for fire-fighting protective clothing. Background technique [0002] The use of velvet fabrics can greatly improve the thermal protection performance of fire-fighting protective clothing fabrics. According to the GA10-2014 "Firefighters' Fire-fighting Protective Clothing" issued by the Ministry of Public Security of the People's Republic of China, the overall thermal protection coefficient (TPP) of fire-fighting protective clothing is ≥ 28, TPP The test is to evaluate the relative performance of clothing thermal protection by measuring the heat energy required to cause second-degree burns (burns) on the surface of the fabric. The higher the TPP value, the better the thermal insulation effect and the better thermal protection effect. Existing firefighting clothing adopts a four-layer structure, including an outer layer, a waterproof and breathable layer, a heat insulation layer and...
