Abstract

The invention discloses a polylactic acid home textile fabric digital printing process, which is characterized in that the process includes the following processes: (1) pattern design; (2) pigment ink preparation; (3) fabric plasma pretreatment; (4) special equipment Digital printing; (5) Baking. The digital printing of the polylactic acid fiber home textile fabric obtained by the method of the present invention has bright colors and good color fastness, and the pretreatment of the fabric does not need to add sizing agent, which saves water and auxiliary agents and reduces pollution, and only needs to use atmospheric pressure plasma pretreatment , improve the adhesion ability of fabric printing, and the post-treatment is relatively simple. It only needs to be baked at a certain temperature, which eliminates the washing stage of the traditional process and saves water resources.

Description

technical field [0001] The invention relates to the technical field of home textile printing, in particular to a pigment digital printing process for degradable fabrics (polylactic acid fiber fabrics). Background technique [0002] Polylactic acid fiber is a fully biodegradable synthetic fiber that can be obtained from grains. After its products are discarded, they can be decomposed into carbon dioxide and water by microorganisms in the soil, and will not pollute the environment. It is a sustainable ecological fiber. The home textile fabric made of it has many excellent properties, such as good resilience, good coloring effect, good moisture absorption and air permeability, and has certain anti-ultraviolet, anti-wrinkle, antibacterial, and flame-retardant properties. [0003] There are no reactive groups on the polylactic acid macromolecules. It is difficult for general dyes to be tightly combined with polylactic acid fabrics. Most of them use pigment printing, and polylact...
