Problems solved by technology

[0004] In order to overcome the current commonly used cold transfer printing production, the printed fabric needs to be pre-treated with a treatment solution containing an alkali agent. Therefore, the printed fabric is transferred tightly with the cold transfer printing paper in a wet state. Defects such as elongation, weft skew and shrinkage will cause the printing pattern to be distorted and seriously affect the product quality. The present invention provides a pretreatment method suitable for cold transfer printing

Embodiment 1

[0032] A new pretreatment method for transfer printing; it is a pretreatment method for transfer printing carriers (paper, plastic film and metal aluminum foil).

[0033] see you first figure 1 As shown, this is a schematic diagram of the commonly used transfer printing pretreatment method at present, and it is a schematic diagram of the pretreatment process of the printed fabric. The printed fabric 2 is sent to the pre-treatment device by the conveying device of the transfer printing machine, and is treated by the pre-treatment liquid in the pre-treatment liquid rolling tank 1 and the padding of the three rolls 3; the processed printed fabric is sent to the transfer through the guide roll The transfer printing device of the printing machine is close to the transfer printing paper 5 fed by the guide roller 4 at the entrance of the transfer printing device, and the transfer printing task is completed by the transfer printing device with the pressing roller 6 on the bottom and t...

Embodiment 2

[0036] One of the contact coating treatment methods of transfer printing carrier is "roller coating method".

[0037] The base materials suitable for transfer printing carrier are paper and plastic film; and suitable for woven (shuttle) fabrics, knitted fabrics and non-woven fabrics to be printed.

[0038] The roller coating method is to use a liquid tank to add pretreatment liquid to the anilox roller, and through the rolling contact between the anilox roller and the ink receiving roller and the transfer printing carrier, the pretreatment liquid is uniformly coated on the transfer printing carrier simultaneously.

[0039] See the specific implementation method image 3Shown: transfer printing carrier 17 (adopting base material to be paper now) is to pass between ink bearing roller 19 and support roller 18, is to be in contact with the circumferential surface of ink bearing roller 19 because of being printed on the transfer printing carrier and the circumferential surface of i...

Embodiment 3

[0041] The second contact coating treatment method of transfer printing carrier is "circular net coating method".

[0042] The base materials suitable for transfer printing carrier are paper and plastic film; and suitable for woven (shuttle) fabrics, knitted fabrics and non-woven fabrics to be printed.

[0043] The circular screen coating method is a method of circular screen printing, which uses a scraper to add pretreatment liquid to the circular screen roller, and through the rolling contact between the circular screen roller and the transfer printing carrier, the transfer printing carrier is synchronously and evenly coated with pretreatment. liquid.

[0044] See the specific implementation method Figure 4 As shown: in the garden net coating method, the pretreatment liquid is sent into the cavity of the garden net roller 20 through the cavity opening scraper 21 by the delivery pump, and the pretreatment liquid is evenly distributed by the scraper 21; The garden screen ro...

Abstract

The invention relates to a new pretreatment method for transfer printing. In the invention, the original padding treatment method applying pretreatment liquid to the fabric to be printed is changed, and a pretreatment method applying the pretreatment liquid to transfer printing paper is adopted. The treatment method comprises the following steps: a transfer printing carrier (the substrates include paper, plastic film and aluminum foil) is treated with the pretreatment liquid through the pretreatment equipment of a transfer printing machine; the side of the transfer printing carrier, with the dye pattern, is required to be treated by the pretreatment liquid; after the treatment, the side of the transfer printing carrier, with the dye pattern, and the fabric to be printed are mutually fitted, and the transfer printing is completed through transfer printing equipment. The pretreatment method solves the problems of original treatment methods that the fabric is easy to have the defects of elongation, offgrain, shrinkage, etc., and the pattern of the printed fabric is distorted, and the product quality is seriously affected.

Description

technical field [0001] The invention relates to a pretreatment method for textile printing and dyeing, in particular to a pretreatment method suitable for cold transfer printing. According to the technical requirements of cold transfer printing, the pre-treatment liquid padding treatment should be performed on the printed fabric first, and then the treated printed fabric and transfer printing paper are closely connected to each other through the transfer printing device to complete the transfer printing task. The opposite pretreatment method is now used, which is to firstly treat the transfer printing paper with the pretreatment liquid, and then close the treated transfer printing paper and the printed fabric through the transfer printing device to complete the transfer printing task. Background technique [0002] Printing pigment or dye patterns on paper, rubber or other carriers, and then pad printing onto the goods to be printed is called transfer printing. The transfer ...
