Garment Direct printing is a kind of direct printing on white fabric or on dyed fabric. The latter is called a hood. , of course, Printing the color of the printed pattern is much more than the background. A large number of common printing methods are direct printing.
If the fabric background is white or mostly white, Printing and the printed pattern looks lighter from the back than the positive color, then we can determine that this is a direct printing fabric (note: Because the printing paste penetration strength is very strong, so the lightweight fabric can not be judged by this method).
If the fabric background is the same shade (because it is a stain), and the printing pattern is much more than the background, then this is the cover printed fabric.
The use of heat after the fiber can produce strong adhesion to the ink, under a small pressure can make the entire ink layer rotation printing paper transferred to the fabric, and then according to the nature of the dye to make the corresponding solid color treatment.
The transfer printing is suitable for the synthetic fabric, and can also be used for the printing of natural fiber pure spinning and its blended fabric. It has the following advantages: The process is short, after printing is finished, do not need steaming, washing and other reprocessing process; simple equipment, small investment, less land, low energy consumption, fine pattern, rich and clear level, high artistic, Printing three-dimensional, strong as a general method of printing, and can print photography and painting style of the pattern; printing color bright, in the sublimation process, the tar in the dye residue in the transfer paper, will not pollute the fabric; Flexibility, the customer selected flower type can be printed in a relatively short time, in addition to the printing of a cloth, but also in the clothing finished product transfer printing, such as the neckline of the jacket, cuffs, pockets of local printing.
Transfer printing also exist deficiencies, Printing such as transfer printing 80% for polyester fabrics, 10% for polyester blended fabrics, 10% for acrylic, nylon and acetate fiber fabrics, for natural fiber fabric has not yet mass production, the use of the scope of a certain limit. In addition to the need to consume a large number of paper, in addition to transfer paper, but also need a backing paper, so the area is printed twice times the size of the fabric, the remaining paper processing is also a difficult problem. Printing and transfer printing production efficiency is lower, a transfer printing machine output of $number m/min, the higher also only 8 m/min, only suitable for small batches of many varieties.
The basic principle of clothing screen printing: Through the unique technology of screen-making, combined with photosensitive exposure characteristics, so that the pattern part of the screen to be printed Conson open state, no pattern part is in a closed state. In the printing, as a result of screen printing squeegee scraping effect, so that the printing pigment paste through screen screen smooth infiltration into the cloth surface, so that printing materials printed on the clothes, so as to complete the printing process. Due to market factors, Printing will lead to the fabric color and variety of fabric varieties.
(1) Clothing slurry printing: only applies to white or light-colored t-shirt printing or other clothing printing, as long as the printing paint ratio reasonable, can do feel soft, Printing high color fastness! But sometimes, there will be some unavoidable shortcomings, because the main ingredient of slurry is water modulation, water, but also a colorless transparent liquid, is unlikely to cover the darker fabric, Printing so it is very difficult to do printing on dark fabrics.
(2) Clothing paste printing: Used for darker color T-shirt printing or other clothing printing, in the selection of printing materials, as far as possible to choose high increased glue paste printing, the purpose is to increase the printing site fastness and elasticity, so that after stretching, printing pattern parts are not easy to crack.
Disadvantage: This kind of printing material, Printing because of its own resin constituent factor, decided that it cannot have slurry printing so soft feel.
Advantages: Can express in the dark fabric you want any a color pattern, and can do the three-dimensional super strong, especially in the printing of cartoon graphics, can be dynamic.
