Problems solved by technology

[0003] In order to solve some problems caused by color fixation in the current cold transfer printing process, for example, fabrics printed with reactive dyes will often cause discoloration when exposed to the air; water-soluble transfer color paste will lose moisture in the fabric moisture content, Causes disadvantages such as a decrease in color fixation rate

Embodiment 1

[0012] The plastic film is selected as polyethylene film (PE).

[0013] Specifications: 0.02mm thickness, 1.6~1.8m width, each roll is 1000m long, and the transfer fabric width is 1.5m.

[0014] See figure 1 As shown, on the cold transfer printing machine, the rolled polyethylene plastic film 2 is placed on the inflatable shaft of the transfer printing machine fixed frame. During transfer printing, the plastic film 2 is fed synchronously through the guide roller 1 and passes through the fabric printing surface 4 printed on the main two rolls 7 and 5. The printed surface is closely bonded, moves with the fabric, and is rolled on the transfer printing machine. Take the frame 3 and wind it together into a reel, then seal the two ends of the film and the fabric with adhesive tape, and wrap the film to seal the outer layer of the fabric. In this way, when the fabric is rolled, it is not easy to cause cross-contamination and contamination of the printed pattern, and it is steamed ...

Embodiment 2

[0016] The plastic film is selected as a polypropylene film (PP) film.

[0017] Specifications: 0.05mm thickness, 1.6-1.8m width, 50kg per roll, about 800 meters long, 1.5m width of transfer fabric.

[0018] See figure 1 As shown, on the cold transfer printing machine, the rolled polypropylene plastic film 2 is placed on the inflatable shaft of the transfer printing machine fixed frame. During the transfer printing, the plastic film 2 is fed synchronously through the guide roller 1 and passes through the transfer printing surface 4 of the fabric transfer surface 4 after the main two rollers 7 and 5 are transferred. Take the frame 3 and wind it together into a reel, then seal the two ends of the film and the fabric with adhesive tape, and wrap the film to seal the outer layer of the fabric. In this way, when the fabric is rolled, it is not easy to cause cross-contamination and contamination of the printed pattern, and it is steamed and baked to fix the color, or the reel is r...

Embodiment 3

[0022] The plastic film is selected as low-density polyethylene.

[0023] Specifications: blow molding grade IPE--0.05mm thickness, width 1800mm, 20Kg / roll, transfer fabric width 1.65m.

[0024] See figure 1 As shown, on the cold transfer printing machine, the rolled low-density polyethylene plastic film 2 is placed on the inflatable shaft of the transfer printing machine fixed frame. During the transfer printing, the plastic film 2 is fed synchronously through the guide roller 1 and passes through the transfer printing surface 4 of the fabric transfer surface 4 after the main two rollers 7 and 5 are transferred. Take the frame 3 and wind it together into a reel, then seal the two ends of the film and the fabric with adhesive tape, and wrap the film to seal the outer layer of the fabric. In this way, when the fabric is rolled, it is not easy to cause cross-contamination and contamination of the printed pattern, and it is steamed and baked to fix the color, or the reel is rot...

Abstract

A film application technology in cold transfer printing color fixing. The film application technology in cold transfer printing and color fixing is carried out on the cold transfer printing machine; after the printed fabric is transferred and before color fixing, the film is covered on the fabric printing surface to block the contact between the air and the fabric, and the film The covered fabric is wound into a reel, and then tapes are used to seal the two ends of the film and the fabric, and the film wrapped to seal the outer layer of the fabric is steamed and baked to fix the color; or the reel is rotated at a low speed to perform cold stacking and color fixation. The cold-fixing method of pad printing, which covers the printing surface of the fabric with a plastic film, prevents cross-contamination and contamination of the printed pattern during the transfer and stacking of the fabric, prevents the loss of water in the additive during color fixing, and improves the cold transfer. The bonded color fixation rate of dyes and fabrics.

Description

technical field [0001] The invention relates to the printing and dyeing industry in the textile industry, in particular to a film application method in color-fixing of cold transfer printing; after transfer printing and before color fixing, a plastic film is covered on the printing surface of the fabric, and then cold An application method of heap solid color. Background technique [0002] Because the transfer printing process can reflect rich layers and vivid color photo effects on the fabric, its exquisite printing effect is even comparable to that of computer jet printing, and the process is more advanced and energy-saving than the traditional printing and dyeing industry, and it is more friendly to the environment. In actual production, the transfer printing process consists of many processes. The printed fabric after the transfer printing process needs to be fixed, and the most commonly used method is steaming and baking or cold stacking. In view of the conventional us...
