Sublimation ink digital jet printing terylene textile fabric and manufacturing method thereof

Abstract

The invention discloses a sublimation ink digital jet printing terylene textile fabric and a manufacturing method thereof. A terylene textile fabric is padded by using padding liquid prepared from high polymers which have pseudoplastic rheological characteristics and are used as main raw materials, then a pseudoplastic backing-away membrane is formed on the surface of the terylene textile fabric, so jetted ink droplets are allowed to only vertically infiltrate into the fabric without horizontal migration after injection. The manufacturing method comprises the following steps: preparation of the padding liquid; padding; and trimming, inspection and rolling so as to obtain a finished product. According to the invention, the sublimation ink digital jet printing terylene textile fabric has good ink absorption performance, a large contact angle is formed after the ink droplets reach the surface through injection, and the ink droplets have sufficient surface tension to maintain original sizes and shapes and have smooth edges.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a polyester textile fabric digitally jet-printed with thermal sublimation ink, and at the same time relates to a manufacturing method of the polyester textile fabric. Background technique [0002] The printing of textile fabrics for advertising, such as advertising flags and publicity flags, has always used the printing technology of clothing fabrics, mainly screen printing technology. Advantages of screen printing: the cost of mass production is low, and the color paste can be better penetrated into the back of the textile fabric through squeegee control, and the back of the thinner textile fabric can also produce the same clear pattern as the front, which is very suitable Banner production requirements. However, screen printing also has more disadvantages: [0003] 1) It takes a long time to make the screen plate and a long time to complete the production process...

AI Technical Summary

Problems solved by technology

[0004] 2) The cost of small batch production is very high. Since plate making, screen printing, steaming and color fixing, and cleaning all require a long cycle and use equipment with high energy consumption, the production of small batches will cost a lot of money, making the market unacceptable

[0005] 3) The production occupies a large area and consumes a lot of energy. Whether it is manual screen printing or machine screen printing, a large working space is required, generally not less than 1000m 2 After printing, steaming, color fixation and pasting cleaning are required, boilers, steam pots and other large energy-consuming equipment are needed to produce heating steam, heating and cleaning hot water, and at the same time, a large amount of sewage of waste color paste and paste cleaning must be discharged, polluting serious environment

[0006] 4) It takes up a lot of labor. Generally, manual screen printing requires about 15 people; even machine screen printing requires about 10 people.

[0007] 5) The pattern expression ability is limited. The screen-printed pattern is a color pattern, which cannot express the gradient of the color, which is far from the color of the real world.

When the inkjet ink droplets are sprayed on the textile fabric, they cannot clearly image and display full colors. The ink droplets will migrate in two directions. One direction is the vertical migration from the surface of the fiber to the back of the textile fabric under the action of gravity. This is the effect we need, which can form the double transparency of the pattern color; but the other direction is the lateral migration along the fiber surface (also known as ink wicking), this migration along the lateral direction of the fiber surface will blur the outline of the pattern, Make the picture unclear and unable to image
