Digital printing method of wool fabric

Abstract

The invention belongs to the technical field of digital printing, and discloses a digital printing method of a wool fabric. The method comprises the following steps of S1, weaving wool yarns into a gray fabric, bleaching the gray fabric, and performing high-temperature treatment and setting; S2, applying cotton yarn paste to the fabric subjected to high-temperature setting, and performing drying; S3, paving the fabric coated with the paste on a digital printer table, and carrying out inkjet operation; S4, performing sealed ageing on the fabric treated in the step S3; S5, performing high-temperature water washing on the aged fabric so as to wash off floating color on the surface of the fabric; and S6, enabling the washed fabric to be subjected to high-temperature setting. The purpose of high-customization and high-dynamic digital printing on the wool fabric can be achieved through the method.

Description

technical field [0001] The invention relates to the technical field of textile production, in particular to a digital printing method for wool fabrics. Background technique [0002] Wool fabric has a smooth and delicate feel, soft luster, excellent texture, and noble color after dyeing or printing, and is favored by consumers. At present, commonly used printing methods include traditional printing and digital printing. There are two main methods of traditional fabric printing and dyeing, one is traditional paint printing and dyeing, and the other is reactive printing and dyeing as opposed to paint printing and dyeing. Digital printing is through digital printers. Printing, digital printing has the advantages of good effect, green environmental protection, and good customization, so it has developed rapidly in the textile printing industry and has been widely used in the printing of cashmere, wool, silk and other high-end fabrics. [0003] However, general digital printers c...

AI Technical Summary

Problems solved by technology

[0003] However, general digital printers cannot directly print on wool products, because there is a certain height of wool fibers on the surface of wool, which will block the nozzle of the printer, resulting in failure to print

There are relatively few domestic all-wool digital printing products, the loss is particularly large, and the color variability is relatively large, which is difficult to control

[0004] Furthermore, the dynamic performance of the electrical drive components of the printer nozzle is relatively poor, and it is impossible to quickly adjust the spraying speed and spraying concentration according to the change of the local characteristics of the woolen cloth (such as roughness, convexity, density) and the change of the printing color. The rapid adjustment of the coating also leads to poor controllability of sprayed coatings. Therefore, it is necessary to propose some technical solutions to solve the above problems
