Problems solved by technology

[0003] At present, the printing method adopts the spot color printing method with several colors and several rollers. Since the printing machine can print up to 16 sets of colors in China, the limitation of the pattern is relatively large. For multi-color and multi-level patterns, Such as landscapes, figures, animals, traditional Chinese paintings, oil paintings, etc. cannot fully express the style of the original manuscript, lacking a sense of three-dimensionality and layering

Abstract

The invention discloses a novel PU printing waterproof and anti-crease new fabric, which comprises three layers: the first layer is PU surface layer mainly comprising PU polyurethane; the second layeris printing dyes; the third layer is a PU surface layer mainly comprising PU polyurethane. The printing dyes in the second layer are ink disperse dyes made of disperse dyes and water-soluble carrier,or ink disperse dyes made of the disperse dyes and alcohol-soluble carrier, or ink disperse dyes made of the disperse dyes and oil-soluble resin. The invention also discloses a method for preparing the novel PU printing waterproof and anti-crease fabric, comprising the following steps: firstly, preparing a shell fabric and a backing material; secondly, carrying out coating operation; thirdly, performing the backing lamination; fourthly, drying, rolling and stripping; fifthly, thermally transferring a printing film to base leather; and sixthly, performing the secondary coating on the printingbase leather. The novel PU printing waterproof, anti-crease fabric has advantages of terrific tensile strength and hydrostatic pressure, and is durable in use, fastness to washing, colorfast; and thepreparation method is easy to operate.

Description

technical field [0001] The invention belongs to the technical field of PU printing, in particular to a new waterproof and anti-wrinkle fabric for PU printing and a preparation method thereof. Background technique [0002] PU (polyurethane, referred to as polyurethane) leather is a kind of fabric that has been loved by people in recent years. With the improvement of people's living standards and the enrichment of material life, people's requirements for the fashion of PU leather fabrics and the pursuit of grades for PU leather products are also becoming more prominent. It not only requires perfection in terms of color and quality, but also has higher requirements in terms of energy saving and environmental protection. This is the combination of modern fashion and reality. Therefore, the market demand for PU leather printing products is also increasing. [0003] At present, the printing method adopts the spot color printing method with several colors and several rollers. Sin...
