Thermal transfer technology (2)

The heat transfer process can be referred to as heat transfer. Heat transfer can be divided into the following categories.

1. High-temperature heat transfer: mainly used for cotton and mixed-spun knitwear. Such as T-shirts, pajamas, and so on. The pattern has a photo effect, soft and elastic parts after ironing.

2. Low-temperature heat transfer: mainly used for nylon and PU artificial leather, such as elastic sportswear, swimwear, down jackets, sports shoes, leather gloves, etc., after the hot pattern with the same high-temperature heat transfer. For elastic clothing, excellent elasticity.

3. Flocking heat transfer: a wide range of applications, usually can be used for women's stockings, men's cotton foam, clothing trademarks, knitted children's clothes, etc., the pattern has a three-dimensional effect, and multi-color match, after the hot soft, elastic, strong adhesion.

4. Infiltration foam heat transfer: mainly used for cotton, chemical fiber sweaters, sweaters, jeans and so on. The main feature is infiltration into the fabric, good air permeability, foam part of the three-dimensional sense of strong, convex texture is good, soft hand after hot, strong adhesion.

Hot stamping methods and precautions.

(1) Align the transfer paper with the pattern on the fabric and place it in the desired position.

(2) Heat with an iron or transfer press for a few seconds.

(3) Remove the backing paper (three methods).

· Cold stripping: After completely cooling, slowly tear off the backing paper.

· Hot stripping: Immediately remove the backing paper while hot.

· Warm off: Wait a few seconds and tear off the backing paper when it is warm.

(4) Silicone paper should be added under the printing surface when hot stockings are used to prevent the hot melt adhesive from infiltrating. General hot stamping process indicators are shown in Table 1, for reference only.
