Abstract

The invention relates to the technical field of textile, and discloses an anhydrous printing method for bio-based nylon 56 fabric, which comprises the following steps: 1) treating the bio-based nylon 56 fabric by using a stabilizer to obtain gray fabric in a pre-treatment scouring process; or the fabric made of the high-stability bio-based nylon fiber is directly used as the gray fabric; and 2) thermal transfer printing or hot melting direct printing. The printing process is simple to operate, basically free of wastewater discharge, energy-saving and emission-reducing, and meets the environmental protection requirement; according to the method, the nylon 56 grey cloth of the common biotechnology is subjected to stabilizer treatment before printing, so that the nylon fabric is protected to a certain extent, and the nylon fabric is prevented from being damaged due to overhigh temperature in the heat transfer printing process or the high-temperature ageing and color fixing process of direct printing. The method disclosed by the invention is particularly suitable for fabrics made of high-stability bio-based nylon fibers, and the nylon fabrics prepared by the method do not need to be treated by adopting a stabilizer, and have the advantages of high printed certified product rate, good dyeing degree, high color fastness and good quality.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for waterless printing of bio-based nylon 56 fabrics. Background technique [0002] The current nylon fabric printing mainly includes: round / flat screen watermark printing, cold transfer printing and digital printing, etc., all of which use acid dyes. In addition to different printing methods, there are processes such as steaming, color fixing, washing, and shaping. There are many processes, complex processes, high energy consumption, and large waste water discharge, which will pollute the environment to a certain extent. [0003] For polyester fabrics, thermal transfer printing is more and more widely used due to factors such as fewer processes, low energy consumption, no waste water discharge, and excellent printing effects, with a better prospect and a relatively mature process. However, for ordinary nylon fabrics, the existing thermal transfer printing process cann...
