Heat transfer printing(2)
Heat transfer printing is a new printing method in the 1950s. First, dye (or pigment) is used to print patterns on paper to make transfer paper, and then the dye (or pigment) on the transfer paper is transferred to textiles under certain conditions.Transfer printing is mainly used in polyester fiber products, with the improvement of transfer printing, in nylon, acrylonitrile, cotton, hemp wool is also widely used.
First, the printing technology integrates green, environmental protection, low carbon, energy saving, emission reduction and ecology, which is a major breakthrough in textile printing technology.After - press fabric, soft feel, bright color, rich layers, good air permeability.
Compared with the traditional process, the thermal transfer printing covers a small area and has a short process.Because the use of dispersed dye sublimation fixation properties can be completely fixed color;The post-treatment process such as fixation and washing is reduced, so the sewage problem is avoided. And the reactive dye is selected as the dye, which is an environmentally friendly printing and dyeing method.The cost of transfer printing is reduced because the liquid absorption of dye on base paper is much less than that of direct printing on fabric.Defects caused by complex color blending and pattern matching can be found on the printed paper and removed before transferring to the fabric, thus ensuring a high rate of integrity of the finished cloth after transfer.For transfer printing, due to the minimal penetration of the base paper, the pattern of transfer prints is clearer, the layers are more distinct, and the color is more uniform.Strong three-dimensional sense, especially in the halftone effect is particularly prominent.
