Manufacturing Methods and Characteristics of Printed Non Woven Fabric

We often see a variety of printed non woven fabric shopping bags with different signs printed on them in supermarkets. What is their printing method? Most of them choose screen printing technology, which is usually called screen printing. Non woven fabric printing is now mainly used for packaging, shopping bags, storage boxes, lockers, disposable tablecloths, etc., which is widely used in life.

 

 

1.What are the features of printed non woven fabric?

The product has obvious concave convex printing and bright colors;

The price of this kind of non-woven fabric is high, and the printing process of printed non woven fabric is relatively expensive. According to the number of colors, one color costs a dime, and more than 50 or 60 cents;

The packaging is in sheet packaging and the speed is slow. Most silk screen printing machines only support sheet packaging printing and cannot use coiled materials for printing. The printing power relying on manual screen scraping is very low.

2.Methods for making printed non woven fabric

With the increasing requirements of the market for non-woven printing products, the above characteristics of screen printing can not be met. Here, we introduce several features:

(1) Offset printing (gravure): this kind of printing technology is to make the pictures to be printed form on the rubber through the protruding method. The plate making process is fast, and then it is printed by machine. Printing is characterized by no damage to ink, low consumption, energy saving and fast. It is characterized by surface printing and limited picture expressiveness.

(2) Copperplate printing (gravure printing): this printing technology is to make the pictures to be printed form depressions on copper and chromium. The plate making process is slow, and then it is printed by machine. It is characterized by exquisite printing and fast speed.

(3) Heat transfer: this method is troublesome. First, the pictures and words are printed on the heat transfer film or heat transfer paper, and then the pictures are transferred to the non-woven fabric by heating the transfer equipment. The commonly used medium in printed non woven fabric is heat transfer film, which has the advantage of exquisite 3D sense and layer sense, comparable to photos.

3.Pigment analysis of printed non woven fabric

Water ink is named after the water-based elastic glue as the printing medium. It is more common in printed non woven fabric, also known as printing. When printing, the color paste is mixed with water-based elastic adhesive. Washing and printing versions do not require chemical solvents, but can be washed directly with water. It is characterized by good coloring power, strong covering power, firmness, washability and basically no odor. Ink has good coloring power and strong color expression, but its environmental protection function is worse than ink. Therefore, the printed non woven fabric bags with strong three-dimensional style and beautiful fashion are more expensive because of the high cost of this method.

The above are all about the printing methods of spunbond non woven fabric. Because the materials, processes and costs used in each method are different, there are differences in prices.
