Environmentally friendly automobile calash warp-knitted interior trimming fabric production process

Abstract

The invention relates to an environmentally friendly automobile calash warp-knitted interior trimming fabric production process. The production process includes the following process steps that a cationic yarn weaving process is adopted to weave a warp-knitted elastic fabric provided with loops on the surface in a one-over-one-down plain waving mode; the warp-knitted elastic fabric undergoes high-temperature setting of 170-190 DEG C on a setting stenter, then the front-side loops discharged from the machine undergo napping and raising by adopting a napping machine to form standing fluffs on the surface, front-side luster finishing is performed, the front-side fluff fabric of the napped fabric undergoes two times of luster finishing treatment at the temperature of 170-180 DEG C by adopting a double-roll luster finishing machine, wherein the luster finishing speed is 10-15 m / min; then, the front-side fluff of the fabric discharged from the machine is trimmed by a circular-knife cropping machine to make fluff length consistent; secondary presetting is performed, the fabric discharged from the machine undergoes high-temperature setting of 180-200 DEG C on the setting stenter to stabilize a fabric structure, and then dyeing and drying steps are performed.

Description

technical field [0001] The invention relates to a production process of an environment-friendly car headliner warp-knitted interior fabric. Background technique [0002] As the demand for automotive textiles in my country increases year by year, the domestic supply of medium and high-grade automotive textiles is less than the demand, and the market gap is relatively large. The annual import value exceeds 4 billion US dollars. Traditional car roof materials use solidified non-woven materials, but they still cannot meet the needs of mid-to-high-end cars, especially for sports cars and convertible models, which require good water resistance, aesthetics, folding resistance, good UV resistance, and certain extensibility and heat shrinkage, etc. . Contents of the invention [0003] The object of the present invention is to solve the above-mentioned technical problems, and to provide a kind of production process of the warp-knitted interior fabric of the environment-friendly car...
