Digital printing color tape for light-color natural fiber textiles as well as preparation method and application of digital printing color tape

Abstract

The invention discloses a digital printing color tape for light-color natural fiber textiles as well as a preparation method and an application of the digital printing color tape. According to the digital printing color tape for the light-color natural fiber textiles, an adhesive material taking water-based hot melt adhesive resins as the main components is mixed with dyes to prepare a digital printing and coating material; films (paper) are (is) coated with the digital printing and coating material by using a special device. A brand new digital printing color tape is prepared from different water-based hot melt adhesive resins and different coloring agents according to different transfer printing materials, wherein the digital printing color tape is simple and convenient in application method, relatively low in cost, is environment-friendly and is suitable for industrial continuous production. The digital printing color tape for light-color natural fiber textiles has the characteristics of simple preparation method, environmental protection effect, low energy consumption and low cost, has the advantages of high accuracy, unlimited color, no waste of production, quick response and wide application range, is capable of being used for directly printing the printed materials, and is excellent in industrial application effect.

Description

technical field [0001] The invention relates to a printing ribbon, in particular to a digital printing ribbon for light-colored natural fiber textiles and a preparation method and application thereof. Background technique [0002] The digital transfer printing method has been popularized on polyester textiles at present. Its working principle is as follows: use the prefabricated transfer paper with materials for receiving sublimation ink as the carrier, print the pattern with an inkjet printer, and then print the pattern on the polyester textile. Apply it flat, and then use a transfer printing machine to heat and pressurize it, and use the principle of disperse dyeing and shaking ink to directly sublimate from a solid state to a vapor state when encountering high temperature to realize transfer printing. Because there are small gaps of 1-10nm in the amorphous area of ​​polyester materials, when the temperature rises above 180°C, the amorphous area moves violently, making the...

AI Technical Summary

Problems solved by technology

Specifically, the base paper is coated multiple times, and the release (release) layer is coated with a solvent-based synthetic resin. The processes involved in these three patents all penetrate into the base paper due to the solvent contained in the coating material. And affect the demoulding (release) effect

Due to the volatilization of organic solvents in coating materials, it brings safety hazards to the environment, the health of operators and the safety of workshops. In order to solve the problem of organic solvents penetrating the base paper, the base paper must be treated with anti-penetration

complicate the manufacturing process

The Chinese patent application number is 200510041227.1, titled: method for wet transfer printing digital color images on cellulose fiber fabrics and its special transfer paper, the rewetting process of transfer printing paper is complicated, the moisture content is difficult to control, and excessive water content will cause Halo color, unclear pattern, low water content will result in low transfer rate and waste products

The Chinese patent application number is 200780018553.8, and the name is: transfer paper for dry transfer printing and dyeing and its dry transfer printing and dyeing method; the Chinese patent application number is 200880012030.7, and the name is: dry transfer of synthetic fiber materials utilizing disperse dyes Printing and dyeing method and transfer paper; when using dry transfer printing, a large amount of hot-melt adhesive resin must be added to the ink-receiving paste layer to effectively bond the paper to the cloth. When it reaches more than 8g / square meter or when several colors are superimposed, it will cause ink piles (ink layer cracks) and become defective products; because too much hot-melt adhesive resin makes it difficult to peel off, there are quite a few hot-melt adhesives Resin adheres to the cloth and causes the cloth to feel stiff
