What are the printing methods and characteristics of non-woven fabrics?

Update:01 Feb 2021
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 various Nonwoven Machine-made Bags in supermarkets with different patterns and logos printed on them. How are these patterns printed?
   Non-woven fabric 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. The concavity and convexity are obvious, and the color is gorgeous;
  2. The price is high. The silk screen is expensive in the printing process of non-woven fabrics. Calculated by the number of colors, one color can be as little as a dime, and as much as fifty or six cents;   
  3, film loading, the speed is slow, most screen printers only support film loading printing, unable to roll printing, printing power by manual scraping is very low.
  With the continuous improvement of the market's requirements for non-woven printing products, the above-mentioned characteristics of silk screen printing are obviously unable to meet. Here we introduce the more commonly used ones on the market:
   1. 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 and chromium in a recessed manner. 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.
 Therefore, the three-dimensional style is strong, and the beautiful and fashionable non-woven bags are more expensive because of the high cost of this method.
   The above are all about non-woven printing methods. Because each method uses different materials, processes, and costs, there are differences in prices.
