Digital printing process for chenille floor mat with natural gradient effect

Abstract

The invention discloses a digital printing process for a chenille floor mat with a natural gradual effect. The process comprises the steps that pretreatment is carried out; a pretreatment solution isprepared, wherein a hydrophilic agent is dissolved in water to obtain the pretreatment solution; the side, with shorter wool, of the chenille floor mat is placed upward, and the pretreatment solutionis atomized and sprayed onto the side, with the shorter wool, of the chenille floor mat; the pretreatment solution diffuses and moves from the end with the shorter wool to the end with longer wool under the action of gravity; inkjet printing is carried out on the back surface of a grey cloth; drying, baking, reduction cleaning and cleaning with hot water are carried out; then softening, washing, spin-drying and drying are carried out to obtain a product. According to the process, natural diffusion of the pretreatment solution in each wool is promoted under the action of gravity, and gradient dyeing of the wool is achieved in cooperation with inkjet printing.

Description

technical field [0001] The invention relates to the technical field of textile digital printing, in particular to a digital printing process for chenille floor mats with natural gradient effect. Background technique [0002] Snow digital inkjet printing is a non-contact and clean textile printing method. It abandons the traditional printing processes such as sketching, filming, screen making and engraving. It has the advantages of energy saving and emission reduction. It is generally optimistic in the industry. new technology. It has the characteristics of high printing precision, short process, small footprint, quick response, energy saving, less pollution, etc., which greatly meets the user's requirements for small batches, multiple colors, and fast delivery. And its product quality and style can fully reflect people-oriented, achieve fashion, personalization, high-tech, high-quality level, to meet the requirements of special handicrafts. At present, low-pile carpets mad...

AI Technical Summary

Problems solved by technology

However, chenille carpets have piles of different thicknesses and heights of 4-35 mm, and the undulating direction of the piles on the same carpet surface is also inconsistent. Therefore, chenille carpet printing is commonly used in rotary screen and flat screen printing, and the flower pattern is only Can be limited to simple geometric patterns

If digital inkjet printing is used, not only the outline of the pattern is not as good as that of rotary screen and flat screen printing, but also because of the difficulty in controlling the amount of inkjet, it is also difficult to control the subsequent infrared color fixing process, and it is easy to burn fluff

[0004] In view of the special structure of the polyester chenille floor mat fabric, that is, the surface of the floor mat fabric has longer polyester chenille plush, it is not only difficult to achieve ideal ink penetration from the top of the plush to the heel in digital inkjet printing processing To avoid or reduce the occurrence of whitening phenomenon, and the dyeing part of each tuft is evenly dyed, and the color does not change, it is difficult to meet the requirements of modern society for chenille mats with gradient fluff
