A Brief Description Of Several Types Of Printing

    1、轉移印花：(英文:tropical print)

First, the pigment is printed on paper to make pfer printing paper, and then pferred to the fabric by high temperature (heating and pressing on the back of the paper). It is generally used in chemical fiber fabrics. Its characteristics are bright colors, fine layers, realistic flowers and strong artistry, but the technology is only suitable for a small number of synthetic fibers such as polyester.

Transfer printing technology is simple, small investment, flexible production, is currently popular in the market. But to be honest, this pfer printing and other printing types comparison, the price is a little high, but there is a certain degree of ~ ~

    2.拔染印花：(英文:wash out colors)

(discharge) discharge print (discharge printing) is dyed with dye which is not resistant to discharge agent. After drying, it is printed with dye dye containing discharge agent or containing discharge dye. After treatment, the dyestuff in the printing area is destroyed and bleed, forming white pattern on the color field or color pattern formed by dye dye.

Also known as white or color pulling.

    3.減量印花：

The process uses the difference in chemical resistance between different fibers in the interwoven or blended fabric, and applies a drawing agent to remove one of the fibers in the fabric, leaving the other fibers to form plucent patterns.

It's also called burn printing or burnt out printing.

    4.皺縮印花：

The printing method can be applied locally to the fabric to make the fibers expand or shrink. Through proper treatment, the fibers of the printing part and the non printing part will be expanded or contracted, so that the products with regular concave convex patterns will be obtained.

Such as pure cotton printed foam with caustic soda as expanding agent.

It's also called bump printing.

    5.平網印花：

The printing die is a polyester or nylon screen mesh with a hollowed pattern on the square rack.

The pattern on the flower plate can be passed through the color paste, and the polymer mesh is used to seal the mesh.

When printing, the flower plate is pressed tightly on the fabric, the color paste on the flower plate is scraped and pressed repeatedly with a scraper, so that the dye paste reaches the fabric surface through the pattern.

Flat screen printing has low efficiency, but wide adaptability and flexible application. It is suitable for small batch and multi variety production.

    6.圓網印花：

The printing die is a cylindrical nickel screen with hollowed pattern. It is installed on the rubber belt of the cycle running in a certain order and can rotate synchronously with the conduction band.

When printing, the color paste is stored in the net and stored in the net bottom. When the round net rotates along the conduction band, the scraper and the net are pressed relative to the net, and the color paste reaches the fabric surface through the web pattern.

Rotary screen printing is a continuous process with high production efficiency. It also has the advantages of roller and peace screen printing. However, there are still some limitations in fine texture and bright color.

Remember: the choice of color and color for rotary screen printing has certain limitations.

    7.顏料印花：(英文:pigment print)

It is also called pigment printing. Since pigment is a water-soluble coloring material, it has no affinity for fibers. Its coloring must be achieved by coating the polymer compound (adhesive) and adhering to the fiber.
