Embodiment 1

[0037] Take 3g of meta-aramid fabric, and prepare a pretreatment solution according to the bath ratio of 1:20. In the pretreatment solution, the mass percentage of N,N-dimethylacetamide is 10%, the mass percentage of sodium silicate is 0.5%, distilled water silicic acid The mass percentage of sodium is 89.5%. After the pre-treatment solution is mixed, stir at 200 rpm for 3 minutes to form a pre-treatment solution. Heat up to 40°C, add the prepared high-performance fabric, continue to heat up to 50°C, and keep it warm for 30 minutes , and then use 10% sodium hydroxide solution to adjust the pH value of the pretreatment solution containing high-performance fabrics to 7 at a rate of 2 drops / min, stir evenly, heat up to 70°C, keep warm for 60min, drain, wash, and 85°C Drying; results in a well dyed high performance fabric. The cationic red FBL is used as the dye, and the preparation of the printing paste is as follows: Disperse Scarlet GS dye 1.5%, water 77.5%, starch 8%, N,N-dime...

Abstract

The invention relates to a high-performance-fabric printing method, and belongs to the technical field of spinning printing and dyeing. According to the high-performance-fabric printing method, a high-performance fabric is chemically pretreated before printing, treating fluid adopts silicic acid gel generated through sodium silicate hydrolysis, N,N-dimethylacetamide is richened in the silicic acidgel, and meanwhile the silicic acid gel is attached to the fiber surface of the fabric. Under the condition of 50 DEG C to 70 DEG C, the N,N-dimethylacetamide opens part of hydrogen bonds between meta-position aramid fiber surface macromolecules, the surface roughness and the porosity of fibers are improved, then under an effect of sodium hydroxide, the silicic acid gel attached on the surface ofthe high-performance fabric is dissolved, the N,N-dimethylacetamide is released, and further acts on the fiber surface in the heat preservation process, and the structure of the fiber surface is further loosened. It is achieved that dye is transferred into the fibers through the common synergistic effect of baking and steaming on the basis of the structure. Therefore, according to the technical scheme, the printing efficiency of the high-performance fabric is improved, and the high-performance fabric can be expanded and applied.

Description

technical field [0001] The invention relates to a high-performance fabric printing method, which belongs to the technical field of textile printing and dyeing. Background technique [0002] A class of fibers with high strength, high modulus or excellent thermal properties or radiation resistance and insulation properties are collectively referred to as high-performance fibers. With the expansion of technical requirements, high-performance fibers are widely used in various fields such as aerospace, aviation and civil use. There are also increasing demands on the surface pattern of high-performance fabrics in use. The Chinese publication "Printing and Dyeing" was published in the 23rd issue of 2013. The title of the article is the printing process of aramid cationic dyes. The sample is stable. Its shortcoming is: the acetophenone that described carrier adopts, and smell is irritating, and is extremely unfavorable to worker's health. Chinese Publication "Printing and Dyeing...
