Printing treatment of ordinary woven bag products in manufacturing process

In the manufacturing process of ordinary woven bags, ordinary woven bags are printed in order to make them look better and have certain advertising effect, but sometimes the printing fastness is poor. Understand the causes and deal with them in time.

The drawing temperature is low, the oven temperature is low, or the temperature distribution is uneven, resulting in the forced drawing of the flat wire at an inappropriate temperature. Low drawing rate. The draft rate is low and the draft degree of raw silk is not enough. Low extrusion temperature. Low extrusion temperature, uneven plasticization of diaphragm and high cooling water temperature. The polypropylene crystal in the diaphragm is too large.

The auxiliary material used in ordinary woven bags is color masterbatch. The yellow pigment with good weather resistance and plastic ordinary woven bags have good aging resistance. Secondly, by increasing the shape and quantity of anti violet colors, the overall aging resistance of knitted fabrics will be affected. The quantity and quality of auxiliary materials are one of the important factors affecting the service life of ordinary woven bags.

Different from other commodities, ordinary woven bags may have some differences in density, grams, weight, color, etc. Therefore, when introducing to customers, words such as "left", "right" and "thick" should be used to explain the characteristics of some ordinary woven bags, so as to avoid unnecessary misunderstanding in the later stage. This is a vague principle, which meets the requirements of customers to a great extent.

In addition, ordinary woven bags need to be checked after production. Only the accurate inspection of ordinary woven bags can ensure the quality of ordinary woven bags. When the staff of ordinary woven bag manufacturers pull us up to inspect ordinary woven bags, we can conduct random sampling inspection first. Manufacturing all kinds of polypropylene ordinary woven bags is a common method in the processing industry of plastic ordinary woven bags. As the processing of ordinary woven bags requires multiple processes, each process may affect the stability of ordinary woven bags, and the addition of filling materials such as calcium carbonate and carbon black will also affect the stability of ordinary plastic woven bags.
