Non-woven printing methods and characteristics

Non-woven printing methods and characteristics. There are many non-woven products on the market, such as polypropylene non-woven fabrics, hot-rolled non-woven fabrics, coated non-woven fabrics, composite non-woven fabrics, and agricultural non-woven fabrics. It is processed by a certain manufacturing process. We often see all kinds of non-woven shopping bags in supermarkets with different patterns and logos printed on them. So how are these patterns printed? 　　non-woven fabrics For printing patterns, most of them use screen printing technology, which is often called 'silk printing'. Non-woven printing is now mostly used for packaging, shopping bags, storage boxes, lockers, disposable tablecloths, etc., which are widely used in daily life. What are the characteristics of non-woven printing screen printing: 　　1, obvious concavity and convexity, bright colors; 　　2, high price, silk screen is more expensive in the non-woven printing process, according to the number of colors, one color is less than a dime. As many as fifty or six cents; 　　3, sheet packaging, slow speed, most screen printers only support sheet packaging printing, unable to roll printing, printing power by manual scraping is very low.　　 With the continuous improvement of market requirements for non-woven printing products, the above-mentioned features of screen printing are obviously unable to meet. Here we introduce several commonly used ones on the market: 　　 One, offset printing (gravure printing). This type of printing technology is to make the pictures that need to be printed are formed on the rubber in a prominent way. The plate making process is fast, and then printed on the machine. The printing characteristics are no ink loss, low energy consumption and fast energy. Its characteristic is surface printing and image expressiveness. limited.　　 2. Copperplate printing (gravure printing). This type of printing technology allows the pictures to be printed to be formed on the copper chromium in a recessed way. The plate-making process is slow, and then printed through the machine. Its characteristics are exquisite printing and fast speed.　　 Three, heat transfer printing. This method is more troublesome, that is, first print the graphics on the thermal transfer film or thermal transfer paper, and then transfer the graphics to the non-woven fabric by heating the transfer equipment. The commonly used medium in textile printing is thermal transfer film, its advantages: exquisite 3D sense, layered, comparable to photos. Non-woven fabric printing screen printing effect, therefore, the style is strong, the beautiful and fashionable non-woven bags are more expensive, because this method is more expensive than the printing method of non-woven fabrics, because of the materials and processes used in each method. , The cost is different, so there is a price difference.　　Non-woven fabric printing pigment problem　　water ink, named after the selection of water-based elastic glue as the printing medium, is more common in textile printing, also called printing. When printing, the color paste and the water-based elastic glue are harmonized. No chemical solvent is needed when washing the printing plate, and it can be washed directly with water. Its characteristics are good coloring power, strong covering and fastness, washing resistance, and basically no peculiar smell.　　 ink has good coloring power and strong color expression, but its environmental protection function is worse than that of ink.　　Buy non-woven fabrics, come to Quanzhou!
