Problems solved by technology

[0003] At present, the biggest defect of inkjet printing for synthetic fiber floor mats is that the product has serious bleeding phenomenon, the pattern definition is not high, the color brightness is poor, and the color fastness to washing and rubbing is not ideal.
Due to the smooth surface of polyester fabric and no active groups, ink droplets in inkjet printing can easily diffuse along the fibers, resulting in blurred printing patterns. High, poor color vividness, becoming a bottleneck in the development of textile inkjet printing technology

Abstract

The invention discloses a pre-treatment method for improving inkjet printing definition of polyester fabric. The pre-treatment method comprises the following steps: applying pre-treatment agent to thesurface of the polyester fabric by adopting a padding method, pre-baking for 0.5 to 1 hour at 40 to 50 DEG C, and drying at 100 to 150 DEG C to obtain pre-treated polyester fabric which can be used for inkjet printing. The concentration of the pre-treatment agent is that 800 to 1,500 mg pre-treatment agent is applied to each square meter of the polyester fabric; the pH value of the pre-treatmentagent is 9 to 10. The mangle expression of the padding method is 65 to 80 percent; the water holding property and the colour fastness of the polyester fabric can be improved by the pre-treatment method; when a colour is fixed by steaming, imbibing and swelling can be performed effectively, which is beneficial for a dye or a pigment to diffuse to fibres; the defect that the definition of printed patterns is not high caused by the effects, such as ink permeating and bleeding, is overcome; the definition of paint and ink ink-jet printing of the polyester fabric are improved; the hand feeling of the polyester fabric can be maintained; the printed colour is brighter.

Description

technical field [0001] The invention relates to the technical field of digital printing, in particular to a pretreatment method for improving the clarity of polyester fabric inkjet printing. Background technique [0002] Digital printing technology is a relatively promising printing technology. It is possible to transform the traditional textile industry by applying its scientific and technological achievements, and realize leapfrog development. In recent years, digital inkjet printing technology has developed rapidly inside and outside the circle, and it is called "a revolution in printing technology". Dadi satisfies the user's requirements for small batches, multiple designs and fast delivery. Moreover, its product quality and style can fully embody people-oriented, achieve fashion, personalization, high-tech, high-quality level, and meet the requirements of special handicrafts. [0003] At present, the biggest defect of inkjet printing for synthetic fiber floor mats is ...
