Problems solved by technology

The main disadvantages of dye inks are: (1) Not universal, different fibers need to use different dye inks, such as cellulose fibers need to use reactive dye inks, protein fibers use acid dye inks, polyester fibers use disperse dye inks, etc. etc., and the nozzles and pipelines need to be cleaned when replacing the ink, which is troublesome to operate
(2) The light fastness of the printed pattern is poor, because inkjet printing is a non-contact printing method, most of the dyes stay on the surface of the fabric and exist in a molecular state, which is easily oxidized by light
Therefore, dye ink not only has complicated process, wastes water resources and energy, but also has a certain degree of environmental pollution.
These shortcomings of dye inks limit the advantages of textile digital inkjet printing technology and seriously hinder the development and application of this technology
[0004] Pigment ink is versatile and can print on any fabric in principle. However, in practical applications, some fabrics have poor water absorption and water holding properties, and the printed pattern is easy to bleed and the coloring is not bright enough. Therefore, it needs to be certain. processing to meet the requirements of inkjet printing

Embodiment 1

[0017] Because cotton and wool fabrics have good water holding properties and the patterns are not easy to bleed, they can be directly printed by inkjet. When printing, it should be noted that due to the poor reflection ability of this kind of fabric to light, the color brightness should be adjusted in image processing. To improve the vividness and color depth of the pattern, the following treatment liquid formula can be used for treatment:

[0018] Cationic dye fixing agent 1%

[0019] Water 99%

[0020] Technological process: The fabric is dried after two dips and two rolling (passing rate 70%), then inkjet printing is carried out, and the finished product is obtained by baking at 150°C for 3 minutes after printing.

Embodiment 2

[0022] Polyester fabrics have poor water absorption, and inkjet printing with water-based pigment inks is prone to bleeding, and can be treated with the following treatment liquid:

[0023] Polyvinyl alcohol 1%

[0024] Polyethylene glycol 0.2%

[0025] Cetyltrimethylammonium Chloride 0.3%

[0026] Water 98.5%

[0027] Technological process: The fabric is dried after two dipping and two rolling (passing rate 50%), ink-jet printing, and then heat-setting at 180°C for 30 seconds to obtain a finished product.

[0028] Due to the good reflective properties of polyester, the pattern generally does not need special treatment. After the fabric is printed by digital inkjet, it can be rolled by a blanket heat transfer machine at 150°C for 1 minute to obtain a better hand feeling.

Embodiment 3

[0030] Although the water absorption of silk fabric is good, its water holding capacity is poor, and it can be treated with the following treatment liquid:

[0031] Polyacrylic thickener 2%

[0032] Water 98%

[0033] Process flow: The fabric is dried after being coated, ink-jet printed, and then baked at 130°C for 3 minutes to obtain a finished product.

[0034] The smoothness of silk fabrics is better, so the images in inkjet printing generally focus on highlighting the sense of hierarchy. After the digital inkjet printing is finished, it can also be rolled with a blanket heat transfer machine at 110°C for 1 minute to get a better hand feeling.

Abstract

The present invention is digital ink jet fabric treating process, and belongs to the field of textile science and technology. The fabric pre-treating process for digital ink jetting and printing with water thinned pigment ink is suitable for fabric of cotton, hemp, silk, Dacron, polyester and cotton blend, acrylic fiber, etc.; and the treated fabric may be ink jetting printed with water thinned pigment ink in one digital ink jetting printer. After printing and proper heat treatment, may be produced printed product with clear pattern, bright color, and high fastness to resist water washing, friction and sunlight.

Description

technical field [0001] The invention discloses a fabric treatment process for digital ink-jet printing, which belongs to the field of textile science and technology. Background technique [0002] Digital inkjet printing technology is a brand-new textile printing technology, which has developed rapidly in recent years and has been practically applied. Compared with traditional printing technology, this technology does not require plate making, is easy to operate, has the advantages of high printing precision, no dye waste, and no pollution. [0003] Inks for digital inkjet printing are mainly divided into two categories, namely dye-based and pigment-based. Dye-based inks are divided into three types: disperse dyes, acid dyes and reactive dyes. At present, dye-based inks are mainly used in inkjet printing of textiles. The main disadvantages of dye inks are: (1) Not universal, different fibers need to use different dye inks, such as cellulose fibers need to use reactive dye i...
