Abstract

The invention discloses a thermosensitive gelatinized direct injection type textile ink and application thereof. The ink comprises the following components in parts by mass: 10-50 parts of disperse dye, 2-40 parts of a dispersing agent, 0.5-1 part of a surfactant, 10-60 parts of an organic solvent, 0.1-0.5 part of an antibacterial agent, 2-20 parts of a block copolymer and the balance of deionized water. By means of block copolymer water system sol-gel transformation, fabric is free of pretreatment, and ink-jet printing can be directly carried out on various fabrics only by heating the fabric to the temperature required by the block copolymer sol-gel transformation. The ink is suitable for any type of polyester fabrics, has universality, is biodegradable, and is non-toxic and harmless. According to the invention, the technological process is greatly shortened; chemical consumption is reduced, and safe production is achieved; and wastewater is not generated in clean production, and the requirement of green ecological textile manufacturing is met.

Description

technical field [0001] The invention relates to the technical field of digital printing ink, in particular to a heat-sensitive gelled direct-injection textile ink without pretreatment and an application thereof. Background technique [0002] In recent years, with the continuous improvement of environmental protection requirements, increased labor costs and changes in market demand, more and more printing companies have begun to transform into the digital printing industry. The digital printing of disperse dyes is mainly used for polyester fabrics. Since the surface of polyester fabrics is smooth and has less polar groups, without any pretreatment, its water resistance and ink resistance are poor, and ink drops are very easy. It diffuses along the capillary movement between the fibers, resulting in unclear outline of the printed pattern. In order to obtain a better inkjet printing effect, there are two methods for disperse dye digital printing: one is to spray the disperse d...
