Abstract

The invention belongs to the field of flame-retardant modification of cotton fabrics, and discloses a multifunctional flame-retardant cotton fabric and a preparation method and application thereof. The preparation method comprises the following steps that plasma treatment is carried out on a cotton fabric to obtain a pretreated cotton fabric; and self-assembly is sequentially carried out on a two-dimensional layered nano material with the thermoelectric sensing characteristic and a polyhydroxy high-molecular compound on the surface of the pretreated cotton fabric to obtain the multifunctional flame-retardant cotton fabric. The preparation method is simple, mild in condition, green and environment-friendly; and the prepared cotton fabric has excellent flame retardant property, further has the functions of sensitive temperature sensing, fire early warning, piezoresistive sensing, electrothermal effect and the like, and can be widely applied to the fields of fire rescue, building decoration, transportation, intelligent electronic skin and the like.

Description

Technical field [0001] The invention belongs to the field of cotton fabric flame retardant modification, and in particular to a multifunctional flame retardant cotton fabric and its preparation method and application thereof. Background technique [0002] Cotton fabrics are widely used in clothing fabrics, home decoration, and transportation and other fields due to excellent biodegradability, biocompatibility, gas permeability, and soft comfort. However, the main component of the cotton fabric is a flammable cellulose material (content of 90%). When it is encountered high temperature or flame, it is easy to generate thermal cracking and oxidative degradation, resulting in a left-handed glucose monomer, and produces a flammable gas. The heat released during the simultaneous combustion feeds back to the surface of the cotton fabric, further promotes the degradation of cotton fabric, thereby forming a combustion cycle until the cotton fabric is completely burned. In addition, once t...
