Description

A device and method for making three-dimensional patterns on the surface of high-precision fabrics

technical field

The invention specifically relates to a device and a method for making a three-dimensional pattern on a high-precision fabric surface, belonging to the technical field of textiles.

Background technique

Textile printing technology is divided into two types: traditional printing technology and textile digital inkjet printing technology. The latter is a printing technology gradually developed after the 1990s. Compared with the traditional printing technology, it is a plateless printing technology that can realize point-by-point control, and it is a revolutionary breakthrough to the traditional printing technology. At present, digital printing products only account for about 3% of the total printing output, and traditional printing occupies a dominant position in the market. The rapid development of the digital printing industry has not been as expected due to the many bottlenecks in the process of digital inkjet printing. First, dye ink digital printing still requires complex post-processing. Subsequent processing procedures such as steaming, soaping, water washing and drying still have problems of high water and energy consumption and pollution. Second, the fiber-selective adsorption properties of dyes lead to limitations in the types of fabrics. Third, the speed of inkjet printing is slow, especially when processing high-precision patterns, the speed of printing is even slower, and it is difficult to meet the requirements of processing speed and processing output.

In view of the shortcomings of dye-based digital printing, the development of pigment-based digital printing technology has received more and more attention in recent years. In order to solve the first and second problems in the inkjet printing process, Chinese patent CN105400292A discloses a reactive dye ink, which includes reactive dyes, auxiliary agents and deionized water, and the auxiliary agents include glycol, urea and surfactants. Chinese patent CN103834232A discloses an ink for inkjet printing of textiles with high fastness. Pigment ink and its preparation method is a processing method in which the pigment ink is sprayed on the pretreated fabric to form a pattern, and then pre-dried and baked to fix the color to obtain a printed fabric. Pigment inkjet printing has the characteristics of short process flow and wide range of applicable fibers. Aiming at the vividness of colors, Chinese patent CN1308544C discloses a fabric treatment process for digital inkjet printing, which is suitable for fabrics such as cotton, linen, silk, polyester, polyester cotton, and acrylic fibers. The pretreatment liquid is a thickener or cationic The aqueous solution of the auxiliary agent, the treated fabric is printed with water-based pigment ink, which can improve the clarity of the pattern and the vividness of the color. Chinese patent CN100500982C discloses a method for improving the image performance of inkjet printing with cationic compounds, which can improve the clarity, color depth and vividness of inkjet printing. It needs to be treated with sodium carbonate and flat O solution to remove the surface of the fabric fiber. residual substance. Chinese patent CN100577911C discloses a method for improving the color fastness of inkjet printing pigment inks. By adding an appropriate amount of crosslinking agent to the inkjet printing pigment ink, the crosslinking agent is utilized in the process of baking after inkjet printing. Film-forming performance, forming a continuous, dense and smooth film on the surface of the fabric, which improves the color fastness of the ultra-fine pigment particles in the ink on the fabric to a certain extent. Chinese patent CN104452339A discloses a method for producing pigment inkjet printed fabrics. The production process includes the following steps: pretreating the pretreated fabrics, and then drying and inkjet printing the pretreated and dried fabrics with pigment inks , and drying, apply color-fixing liquid to the fabric after inkjet printing drying, and dry, and then bake to fix the color. The color-fixing liquid applied in the step can be one or a combination of adhesives, softeners, cross-linking agents, and color-fixing agents, and the application method is liquid spraying. The pigment ink-jet printing fabric processed by the method has the advantages of bright color and high fastness. The binder is used as a film-forming substance to cover and fix the colorant pigment on the surface of the fiber to complete the printing coloring process. Since pigments are non-selective to fibers, it greatly broadens the adaptability of digital printing to printed fabrics. At the same time, the post-process of pigment-based digital printing only needs to be baked, which greatly shortens the post-process, reduces water consumption and waste water discharge, and conforms to the development direction of ecological dyeing and finishing and clean production. Huang Yi and Shao Jianzhong mentioned in their doctoral dissertation "Research on Digital Jet Printing Technology of Blue Light Curable Pigments for Textiles" that they optimized the composition of the high-efficiency blue light-initiating system, the construction of a low-viscosity flexible polymerization system, the compatibility of colorants and pigments with the polymerization system, and the blue light The application performance of curable pigment ink and fabric printing effect provide theoretical guidance for the research and development of blue light curable pigment inkjet printing ink and related application technologies suitable for textiles.

The above invention either improves the color performance of the pigment ink inkjet printing by pretreating the fabric, or improves the color fastness of the ultrafine pigment particles on the fabric by adding an appropriate amount of crosslinking agent to the inkjet printing pigment ink. But the printing that produces three-dimensional pattern is not seen in the report.
