Heat transfer printing method and equipment for fiber texture network sandwich

Abstract

The invention provides a heat transfer printing method and equipment for a fiber texture network sandwich. The heat transfer printing method comprises the steps that the fiber texture network sandwichand transfer printing paper are attached together and rotate around a heating roller at the same speed, the fiber texture network sandwich and the transfer printing paper are heated to a heat transfer printing temperature through the heating roller, so that dye on the transfer paper is transferred onto the fiber texture network sandwich; longitudinal stress and transverse stress are applied to the fiber texture network sandwich subjected to transfer printing treatment; and the heat transfer printing temperature ranges from 180 DEG C to 250 DEG C, and the heat transfer printing heating time ranges from 5 s to 50 s. According to the heat transfer printing method and equipment for the fiber texture network sandwich, longitudinal stress and transverse stress are applied to the fiber texture network sandwich subjected to heat transfer printing, so that shrinkage stress, caused by heat transfer printing, of the fiber texture network sandwich is eliminated, the fiber texture network sandwichis smooth, shrinkage is reduced, and the situation of surface wrinkling or unevenness is avoided.

Description

technical field [0001] The invention relates to thermal transfer printing technology, in particular to a thermal transfer printing method and equipment of fiber texture network sandwich. Background technique [0002] Thermal transfer printing (also known as thermal transfer printing) is a new printing and dyeing process that has gradually emerged internationally in recent years. First, use printing technology to print special dyes (water-based or oil-based sublimation dyes) and print all required patterns on special paper to make transfer printing paper (also known as transfer paper) with various fancy patterns. , and then on the transfer printing machine, after the side of the transfer printing paper with the pattern printed on it is tightly bonded to the printed fabric, through the action of heating and pressure, the dye of the printing paper is sublimated and transferred to the printed fabric. Various patterns are formed on the printed fabric. [0003] The fiber texture...

Problems solved by technology

[0005] When the fiber texture network sandwich is transferred and printed on the existing thermal transfer printing equipment, shrinkage deformation caused by temperature difference will occur, resulting in dimensional deformation of the printed fiber texture network sandwich
