A kind of matte polyester film for fabric cold transfer printing and its preparation method and application

Abstract

The invention relates to a matt polyester thin film for fabric cold transfer printing, and a preparation method and application thereof. The matt polyester thin film is mainly prepared from the following raw materials in percentage by mass: 20 to 80 percent of silicon series polyester slices, 0.1 to 40 percent of full-dull polyester slices, 10 to 40 percent of waste and old polyester material regeneration particles and 5 to 50 percent of bright polyester slices, wherein the mass content of silicon oxide in the silicon series polyester slices is 3000 to 12000mg / kg; the particle size range of the silicon oxide is 2 to 10mu m; the mass percent content of titanium oxide in the full-dull polyester slices is 2.0 to 3.0 percent. The matt polyester thin film has the advantages that the thickness is thin; the haze degree is high; the glossiness is low; the matt polyester thin film is used as a transfer printing carrier in the fabric cold transfer printing process; the transfer printing effect is good; inevitable printing white dots of a traditional transfer printing carrier cannot occur; meanwhile, the preparation method is simple and convenient; the raw material sources are wide; the matt film does not need the subsequent coating coating process; the redundant coating technological process is reduced; the cost is reduced.

Description

technical field [0001] The invention belongs to the field of polymer material processing, and in particular relates to a matte polyester film for fabric cold transfer printing and its preparation method and application. Background technique [0002] Matte polyester film is mainly used in thermal transfer film, bronzing film, hot cloth, leather, transfer paper, decorative sheet profiles, aluminized color printing packaging, signs and other products. According to the size of glossiness, matte polyester film is usually divided into three categories: low matte, medium matte and high matte. At present, there are few high-dumbness products on the market (definition of high-dumbness film: the haze is greater than 95%, and the gloss is less than 17%), and most of them are low-dumbness and medium-dumbness products. [0003] High-matte matte polyester film can be applied to transfer products such as high-end cosmetic packaging, high-end decorative sheet profiles, transfer cigarette p...

Problems solved by technology

The release agent, release agent, and ink carrier are mostly organic solvents, which pollute the environment, and the coating effect of these solvents has a direct impact on the quality of the fabric, resulting in increased production costs and operational difficulties for enterprises, and downstream customers Printing white spots are prone to defects during use, and white spots will also appear on the surface of the fabric after transfer, which will affect the final quality of the product
