Abstract

The invention relates to a flame-retardant antistatic fabric for the coal mining industry, and belongs to the technical field of fabric preparation. The preparation method comprises the following steps of firstly, heating and melting polypropylene serving as a raw material, adding ammonium polyphosphate and glycerol into a polypropylene melt liquid, mixing, and then spinning by a melt spinning device to prepare flame-retardant modified polypropylene fibers, then carrying out ultrasonic oscillation dipping treatment on cotton fibers by using a phytic acid solution, and then putting the processed cotton fibers into a silver nitrate solution for dipping activation, enabling the activated cotton fibers to be subjected to heat treatment in the propylene atmosphere, preparing modified cotton fibers, finally, blending the flame-retardant modified polypropylene fibers and the modified cotton fibers, and obtaining the flame-retardant antistatic fabric for the coal mining industry. The flame-retardant anti-static fabric for the coal mining industry is high in flame retardance and strong in anti-static capacity, and has a wide application prospect.

Description

technical field [0001] The invention relates to a flame-retardant and antistatic fabric for coal mine industry, which belongs to the technical field of fabric preparation. Background technique [0002] Chemical fibers (such as polyester) have been widely used in clothing, decoration, industry and other fields due to their good wear resistance, stiffness, elasticity, and chemical corrosion resistance. [0003] Compared with natural cotton and other fibers, chemical fibers have high strength, good cloth surface texture, bright color, reasonable price, and easy processing, which are deeply loved by consumers. However, because chemical fibers are hydrophobic fibers and lack hydrophilic groups in their molecules, resulting in poor hygroscopicity, easy pilling, and static electricity, it is easier to accumulate static charges in a low-humidity environment. , Twisting, weaving and knitting, dyeing and finishing, etc. will have certain difficulties in each production process, and e...
