Single-layer double-sided heat transfer printing process for polyester blankets

Abstract

The invention discloses a single-layer double-sided heat transfer printing process for polyester blankets. The printing process includes the steps of 1), pretreatment; 2), double-sided printing; 3), over-hydrolyzed untwisting ; 4), drying; 5), brushing; 6), aftertreatment; 7), production of finished products. In the printing process, the single-layer double-sided magnetic rod printing technology of traditional polyester blankets is innovated, good permeability of blanket fiber in the printing process with a heat transfer printing machine is achieved, and the printing process is simple, clear and time saving and labor saving; continuous washing and fixing of high-temperature evaporated flowers using over-hydrolyzed untwisting instead of traditional magnetic bar printing machines greatly reduces the amount of water used and can guarantee the untwisting degree of the blanket fiber, functions in energy saving and no sewage treatment are imperceptibly achieved, and the concept of green environmental protection production is met; most importantly, the effect of printing is quite realistic and can be matched with digital printing heat transfer printing paper, traditional heat transfer printing paper can be used as well, and a wide market prospect is achieved.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a single-layer double-sided thermal transfer printing process for polyester blankets. Background technique [0002] Blanket is a kind of commonly used bedding, which has the function of keeping warm. Compared with the quilt, it is thinner. Its raw materials are mostly animal fibers (such as wool, mohair, rabbit hair, cashmere, camel hair, yak hair) or chemical fibers such as acrylic fibers and viscose fibers. , and some are made of blends of animal fibers and chemical fibers. Wool fabric with rich plush on both sides, rich plush on the surface, wool fabric for bed with thermal performance, and can also be used as bed covers, tapestries and other decorations. There are three types of blankets: pure blankets, blended blankets, and chemical fiber blankets. According to the weaving method, they are divided into organic weaving, tufting, warp knitting, acupuncture, stitch...

Problems solved by technology

[0006] In order to solve the above problems, the present invention discloses a single-layer double-sided thermal transfer printing process for polyester blankets. The single-layer double-sided thermal transfer printing blanket has different patterns and colors on the front and back sides, giving people a new visual feeling, which is different from the existing technology. One-sided printing can also be used for secondary transfer printing and double-sided printing to meet the technical requirements of single-layer double-sided different flowers. The heat transfer printing machine is used. The printing process is simple, and there is no need to print the front and back of the blanket twice to fix the color. In the printing process, a large amount of water will not be used for washing and color fixing, which will protect the environment, save water resources, and reduce the cost of double-sided printing. The process is simple and clear, saving time and effort, and conforms to the concept of green and environmentally friendly production.
