Problems solved by technology

The disadvantage of pretreatment is to form a thermoplastic film on the outer layer of the natural fiber fabric to accept disperse dyes, or to chemically denature the natural fiber, which will deteriorate the moisture absorption and perspiration, air permeability and other properties of the natural fiber, and affect the fastness of the product. and feel have certain influence
[0003] The cotton rotary screen transfer printing process uses a rotary screen printing machine to process the transfer printing paper. The transfer paper used is 76g / m2 offset paper. The disadvantage is that it cannot print the "photographic" pattern with a good transition effect. high cost

Embodiment Construction

[0018] Requirements for gray fabric: smelting, refining and whitening to become mercerized fabric.

[0019] A transfer printing process for natural fiber fabrics, which includes the following steps

[0020] (1) Coating process, that is, coating the surface of the web;

[0021] (2) The printing process, that is, printing the surface of the web to make transfer printing paper, and the dyes used for printing are reactive dyes;

[0022] (3) Transfer process, the gray cloth of natural fiber fabric is soaked in lye and then rolled dry, and the transfer printing paper and the gray cloth are pressurized to free the dye on the paper and transfer and penetrate into the inside of the gray cloth.

[0023] Described coating comprises the composition of following weight ratio

[0024] Coating material: 1-50%

[0025] Nonionic surfactant: 1-20%

[0026] Preservatives 1-10%

[0027] The rest are organic solvents.

[0028] Described coating material comprises stearate, polyethylene glyco...

Abstract

The technology of transfering printing for natural fabric, involves the follow working procedure: first, coat the surface of the web; secondly, printing on the surface of the web, finally, marinate the crude fabric to make the dye dissociate out of the paper and transfer to infiltrate crude fabric. Variegation and fastness ability of the natural fabric is great due to using water-solubility active dye and every firm target is advanced by 1-1.5 level. In short, this working procedure can make the images clearer and various transition.

Description

technical field [0001] The invention relates to a transfer printing process of natural fiber fabrics. Background technique [0002] In the prior art, Chinese Patent No. 96108188.0 discloses a transfer printing pretreatment agent and printing process for natural fiber fabrics. By pretreating natural fabrics, the hydroxyl groups of natural fibers are closed, and the principle of sublimation of water-insoluble dyes is used. Transfer printing is completed under high temperature conditions. The disadvantage of pretreatment is to form a thermoplastic film on the outer layer of the natural fiber fabric to accept disperse dyes, or to chemically denature the natural fiber, which will deteriorate the moisture absorption and perspiration, air permeability and other properties of the natural fiber, and affect the fastness of the product. And feel have certain influence. [0003] The cotton rotary screen transfer printing process uses a rotary screen printing ...
