Problems solved by technology

Low-temperature plasma treatment of textile materials can change the chemical structure and morphology of the fiber surface, but the deepest penetration into the surface of the material is no more than 10 μm, and the thickness of some treatments is only about 10 nanometers, and about 99.8% of the body is still intact. Therefore, after treatment There is no significant change in the chemical and physical properties of the fiber, but its dyeing performance can be significantly improved

specific Embodiment 1

[0019] A plasma-crosslinking composite modified high-precision cashmere digital printing process, comprising the following steps:

[0020] (1) Cashmere fabric by steaming process: the cashmere fabric is in a loose state, sprayed with 0.3g / L antistatic agent SN, and the fiber weight gain is 100g / m 2 , the fabric is steamed in a J-type steamer at 20 m / min, and steamed at 100 °C with steam or hot air as the medium;

[0021] When the cashmere fabric is in a loose state, the antistatic agent is sprayed and steamed to improve the wetting performance of the cashmere fiber and soften the scale layer structure on the surface of the cashmere fiber, which is beneficial to the subsequent plasma etching and improves the etching effect.

[0022] (2) Plasma etching process of cashmere fabric: AtomfloTM250 atmospheric pressure plasma jet equipment is used to form a plasma jet to modify cashmere fabric. The processing conditions are as follows: medium air, power supply parameters 380V, freque...

Abstract

The invention discloses a plasma-crosslinking compound modified high-precision cashmere digital printing process, comprising the following steps: (1) cashmere fabric steaming process; (2) cashmere fabric plasma etching process; (3) cashmere fabric Cross-linking agent gluing process; (4) cashmere fabric digital printing machine jet printing process; (5) heating and curing to obtain finished products. The present invention uses low-temperature plasma to pretreat cashmere fibers, physical etching and chemical oxidation occur on the cashmere surface, and oxygen-containing groups are introduced to endow cashmere with excellent hydrophilic effect and use 3‑(2,3‑glycidyloxy)propane Trimethoxysilane treated fibers to improve the digital printing performance of cashmere fibers and improve the ability of cashmere fibers to absorb ink. After printing, there is no need to steam and wash to obtain bright and clear patterns, simplify the printing process, and the printing is flexible, which can meet the needs of personalized and quantitative production, small batches and rapid response.

Description

technical field [0001] The invention belongs to the field of digital printing, and in particular relates to a plasma-crosslinking composite modified high-precision cashmere digital printing process. Background technique [0002] Digital printing is a model of the combination of computer technology and traditional textile printing technology. It has the characteristics of low energy consumption, less sewage discharge, no need for plate making, fast pattern change, strong layering of printed patterns, and many color changes. The color and size of the pattern can be adjusted at any time, which is difficult to achieve by conventional printing. [0003] As people's calls for environmental protection are getting higher and higher, green and ecological textiles have become the basis for the sustainable development of the textile industry, and the development of surface modification processes for materials with little or no pollution to the environment has become a major research di...
