Non-woven bag printing process

Non-woven bags are generally used in screen printing process, which is often said'Silk Screen' This has always been a printing process commonly used by many manufacturers. Generally, it is printed manually. Because the printing has odor, the color is not full and easy to fall off, so many new non-woven printing methods have emerged. Here we introduce several mainstream ones on the market: first, the watermark, named for its use of water-based elastic glue as a printing medium, is more common in textile printing, also known as printing. The color paste and the water-based Elastic Glue are mixed during printing. When washing the plate, no chemical solvent is used, and it can be washed directly with water. It is characterized by good tinting strength, strong covering and fastness, washable resistance, and basically no odor. Generally used for printing: canvas bag, cotton bag, second, intaglio printing, the finished product processed by this method is usually called laminated non-woven bag. This process is divided into two steps, that is, the traditional gravure printing process is used to print the picture and text onto the film, and then the patterned film is compounded on the non-woven fabric by the film coating process. Generally, non-woven bags printed with large-area color patterns adopt this process. It is characterized by exquisite printing, machine production in the whole process and short production cycle. In addition, the product has excellent waterproof performance, and the durability of the finished product is better than that of non-woven bags produced by other processes. The film is available in both bright and Matt, and the Matt has a matte effect! The product is stylish, durable, full of color, realistic patterns, and the disadvantage is that the price is relatively expensive. Third, thermal transfer is a special printing in printing! The method requires an intermediate medium, I . e. the picture and text are first printed on a thermal transfer film or thermal transfer paper, and then the pattern is transferred to a non-woven fabric through a transfer device for heating. The medium commonly used in textile printing is thermal transfer film. Its advantages are: beautifully printed, rich in layers, comparable to photos. Suitable for small area color image printing. The disadvantage is that the printed pattern is easy to fall off and expensive.
