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 cloth, which is a fiber material, specifically including fiber material in the form of woven, knitted or non-fabric, and adopts flame-retardant technology. The flame retardant finishing solution of body, surfactant and high-concentration polyethylene makes it have durable flame retardant performance, and the flame retardant performance does not decrease with the increase of washing times, and this flame retardant finishing does not change the fabric The original characteristics of the fiber, the fabric feels soft, the loss of strength is small, and the comfort and durability of the fabric are basically maintained. It has the characteristics of carbonization in case of fire, self-extinguishing after leaving the fire, and effectively preventing the spread of flames. The protective clothing made of it It can prevent the flame 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 Formatio...
