Notes on the home textile fabric printing and dyeing knowledge

Dozens of bedding kits and thousands of products "wrenches", a round of low-cost goods completely defeated, and not only lose the fabric, in the printing and dyeing methods and dye costs can not be compared, and this point Consumers often drift directly as clouds. Experts remind that the printing and dyeing methods not only affect the color effect, but also directly touch the use of security, if the improper dye selection in printing and dyeing, most likely with inferior wood, paint, let formaldehyde organic.

Fabric printing and dyeing process includes: reactive printing, paint printing.

Active Printing and Dyeing: Active Printing and Dyeing is Enveloping, Active Printing and Dyeing In the process of dyeing and printing, active dyes and fiber molecules combine to form a whole with dyes and fibers. Relatively speaking, there are many active printing and dyeing processes, and the difficulty is also relatively high. The fabrics of active printing and dyeing are of good color and are soft to the touch. They are relatively high-end printing and dyeing methods and are 20%-30% more expensive than coating and dyeing, and the prices of the products are also relatively expensive. some.

Coating printing and dyeing: Bedding wears "flower jacket" relying on coating printing and dyeing to support the waist. Coating printing and dyeing is the use of water-insoluble colored substances (pigments) and high-molecular polymer (binder) mixed on textiles, after certain treatment in textiles. A transparent colored film is formed on the film, and the coating is then mechanically fixed onto the textile. Compared with active printing and dyeing, coating printing and dyeing has more “safety risks”. The price of paints used in printing and dyeing can sometimes differ greatly. A few dozen cheap paints can buy one kilogram. Some good paints cost hundreds of dollars per kilogram. The quality of paints directly determines the quality of printing and dyeing and the safety of use. .

Bedding mostly uses paint printing and reactive printing. The color fastness of paint printing is good but the feel is hard. After soft treatment, the expected effect can be achieved. The active printing is not resistant to sunlight, but the hand feels better.

Flat screen printing: If you need a big apple to dress up in the middle of bedding, you have to print on flat screen. Therefore, the printing method is straightforward and straightforward, especially when it is used to express a large area of ​​the overall pattern.

Digital printing: Digital printing is easy to sample and there is no limit to the amount. Therefore, personalized customization can be achieved, and some unique products can be produced. However, if it is a design that enters the market in large quantities, it is not appropriate.

Rotary Screen Printing: For example, if there are duplicate apples on bedding, it is achieved through rotary screen printing. In this printing method, the net is a circle, so that expressing small material is more vivid.
