Impressió per transferència de calor (1)

La impressió per transferència de calor és un nou mètode d’impressió als anys cinquanta. En primer lloc, el tint (o pigment) s’utilitza per imprimir patrons sobre paper per fer paper de transferència, i després el colorant (o pigment) del paper de transferència es transfereix als teixits en determinades condicions. La impressió de transferència s’utilitza principalment en productes de fibra de polièster, la millora de la impressió per transferència, en niló, acrilonitril, cotó i llana de cànem també és àmpliament utilitzada.

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.
