Problems solved by technology

[0002] In firefighting work, firefighters work at high temperatures, and the temperature at which the human body can move at high temperatures is limited. Working at high temperatures for a long time will cause life danger. Although the existing firefighting clothing at that time had certain fireproof performance, it was not effective. Real-time detection of temperature conditions in the environment, so that firefighters cannot be vigilant according to temperature changes in high-temperature environments

Abstract

The invention discloses a preparation process of wear-resistant and fire-resistant cloth. The specific preparation process is as follows: the first step is to add the color-changing polymer into the acetone solution and stir to dissolve it, then add porous polybenzamide phosphate fiber to it, and dip it at room temperature for 30 ‑40min, then filter and dry; in the second step, the dried porous polybenzamide phosphate fiber is stirred and mixed in the flame retardant colloid for 20‑30min, then dried, and the dried wear-resistant fiber is woven into yarns, and then weave the obtained yarns into fabrics to obtain wear-resistant and fireproof fabrics. The porous polyphenylamide phosphate fiber prepared by the present invention has a certain fire resistance, and the surface of the fiber and the internal space are filled with flame retardant colloid, so that the fire performance of the fiber is improved, and the high strength is realized from the inside to the outside. Fire prevention effect.

Description

technical field [0001] The invention belongs to the field of cloth preparation and relates to a preparation process of wear-resistant and fireproof cloth. Background technique [0002] In firefighting work, firefighters work at high temperatures, and the temperature at which the human body can move at high temperatures is limited. Working at high temperatures for a long time will cause life danger. Although the existing firefighting clothing at that time had certain fireproof performance, it was not effective Real-time detection of temperature conditions in the environment, so that firefighters cannot be vigilant according to temperature changes in high-temperature environments. Contents of the invention [0003] The purpose of the present invention is to provide a preparation process for wear-resistant and fire-resistant cloth. By preparing porous polybenzamide phosphate fibers, the surface and interior of the fibers are impregnated with color-changing polymers, and then ...
