I don’t know how much you know about pet wet-laid non-woven fabrics. Today I will take you through Let’s take a closer look at this material.
Wet-laid non-woven fabrics, a brand-new fiber product, are very different from woven fabrics and knitted fabrics due to their structural characteristics. They are basically composed of fiber networks (not yarn networks) like structures. As long as different fiber raw materials are selected, different processing methods are combined with different finishing processes, non-woven products with widely varying properties and wide uses can be made. It is widely used in many fields.
PET wet-laid non-woven fabric is made by dissolving the fiber-forming polymer in an appropriate solvent to obtain a solution with a certain composition, a certain viscosity and good spinnability, which is called spinning solution. The spinning dope can also be obtained directly from homogeneous solution polymerization. The polymer swells before dissolving, that is, the solvent first penetrates into the polymer, increasing the distance between the macromolecules, and then dissolves to form a uniform solution. The whole process takes a long time, and the speed of the swelling process has an important impact on the dissolution rate.
