Printing process of flame-retardant fabric with high content of aramid fibers

Abstract

The invention discloses a printing process of a flame-retardant fabric with the high content of aramid fibers. The printing process mainly comprises the process steps of preferential selection of dyestuff, preparation of color paste, printing of patterns, fabric roasting, rapid steaming reduction, primary washing, soap-boiling, secondary washing, drying, tentering, preshrinking and finished product inspection. When a flame-retardant textile fabric with the high content of aramid fibers is printed, reduction dyestuff and paint which are easy to purchase from the market are preferentially selected, compatibility and matching performance tests are carried out on the reduction dyestuff and the reduction-tolerance liquid paint, the preparation proportion of the reduction dyestuff to the preferentially-selected paint is selected according to different colors, the color paste in different colors required during printing is prepared, and the flame-retardant fabric with the high content of aramid fibers is printed by the reduction dyestuff and the paint in the same color paste. By means of the printing technology, the technical problems in printing of aramid fiber fabric products are successfully solved that in current printing and dyeing industries, the process route for printing flame-retardant textile fabrics with the high content of aramid fibers is complicated, the production period is long, the cost is high, and the quality is poor; the production cost is lowered, and the economic benefit of enterprises is increased.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a printing process for flame-retardant fabrics with high aramid content. Background technique [0002] The full name of aramid fiber is "polyphenylene diamide fiber", which is Aramid fiber in English. , anti-aging, long life cycle and other excellent properties, its strength is 5 to 6 times that of steel wire, its modulus is 2 to 3 times that of steel wire or glass fiber, its toughness is 2 times that of steel wire, and its weight is only 1 / 5 of steel wire Around, at a temperature of 560 degrees, it does not decompose and does not melt. It has good insulation and anti-aging performance, and has a long life cycle. The discovery of aramid fiber is considered to be a very important historical process in the material industry. Widely used in composite materials, bulletproof products, building materials, special protective clothing, electronic equipment and othe...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a high aramid content flame retardant fabric printing process for the shortcomings of the existing fabric fabric printing technology with high aramid content. Select a reducing solution-resistant paint series, mix it with vat dyes, and use vat dyes and reducing solution-resistant coatings to print patterns and color the same paste on flame-retardant fabrics with high aramid content. The flame-retardant clothing fabric with high aramid content can be printed and dyed in various colors and patterns (required by users), and different anti-infrared curves can be obtained by optimizing and adjusting the dosage of various vat dyes and coatings in the color paste prescription , to achieve the anti-infrared effect required by users
