Problems solved by technology

However, the production technology used in the current flame-retardant fabrics is all originated from the British Aowei Company. The raw material they use is tetrakis hydroxymethyl phosphorus chloride (THPC), but there are halogens in THPC, there are non-environmental factors, and it is flame-retardant. The effect is not very stable, and the flame retardant performance will decrease with the increase of washing times
In addition, "Study on the Toxicity of Tetrahydroxymethylphosphorus Chloride-Urea Initial Contraction" published by Wang Liyun et al. shows that the decomposition of THPC will produce formaldehyde, which has adverse effects on the human body.

Abstract

The invention relates to a flame-retardant fabric, which is made of fiber materials, and specially comprises fiber materials in a weaving, knitting or non-woven form. The flame-retardant fabric is prepared by using a flame-retardant process, and the main ingredients of the flame-retardant fabric include a low molecular pre-shrinking body of tetrakis hydroxymethyl phosphonium sulfate (THPS) and amide, a surfactant, a flame-retardant finishing liquid of high-concentration polyethylene, so that the flame-retardant fabric has a durable flame retardant performance, and the flame retardant performance is not reduced with the increasing of the number of washing times; the flame-retardant finishing does not change the original features of the fabric fibers, so that the fabric is soft in handfeel, and small in strength loss, and the comfortableness and durability of the fabric are basically kept, therefore, the flame-retardant fabric has a characteristic that the fabric is carbonized after meeting fire and self-extinguished after leaving fire, and the spread of flames is effectively prevented; and the protective clothing prepared by using the fabric can prevent flames from causing harm to the human body.

Description

technical field [0001] The invention relates to a flame-retardant cloth, which belongs to the technical field of textile and clothing. Background technique [0002] Due to the nature of work, clothing fabrics in many industries need to have special properties. For example, domestic and foreign petrochemical, natural gas, fire protection, military police, aviation and other industries all require clothing fabrics with fire-resistant and flame-retardant properties. However, the production technology used in the current flame-retardant fabrics is all originated from the British Aowei Company. The raw material they use is tetrakis hydroxymethyl phosphorus chloride (THPC), but there are halogens in THPC, there are non-environmental factors, and it is flame-retardant. The effect is not very stable, and the flame retardant performance will decrease with the increase of washing times. In addition, "Study on the Toxicity of Tetrahydroxymethylphosphorus Chloride-Urea Initial Formati...
