What is dryer fabric?

Dryer fabric is mainly used in the drying part of paper machine, its main function is to transfer wet paper and in the process of transferring paper through the front group of drying cylinder drying.

Flat yarn dryer fabric

Because of its high fabric strength, good air permeability and high drying efficiency, the double warp flat yarn dryer fabric is more often used for ordinary packaging paper which does not require high paper surface performance.

Spiral dryer fabric

Spiral dryer fabric is characterized by dirt resistance, nearly seam-free design, high abrasion resistance, and easy cleaning; the side effects are obvious mesh marks on the paper surface.

Main materials

The main material of dryer fabric is polyester monofilament, which is divided into round yarn and flat yarn, and the woven fabric is divided into round yarn dryer fabric and flat yarn dryer fabric, from the customer's use effect, the effect of flat yarn is better than round yarn.

Anti-pollution

In addition to the design of the geometry of the wire to avoid dryer fabric pollution, the adhesion of adhesives also requires the addition of fluorine in the polyester material to reduce its surface energy, resulting in pollutants are not easy to adhere to the surface, so it also greatly reduces the dryer fabric because of dirt caused by the black particles of adhesives, air permeability caused by the lack of drying capacity, uneven moisture across the width of the paper machine, black spots and other paper diseases. occurrence.

Anti-hydrolysis

As the dryer fabric operating environment is mainly inside the airtight hood, the environment is in a serious high temperature and high humidity environment. In addition, the pH of some virgin papers is not neutral, so it is very corrosive to polyester materials. The end of life of most dryer fabrics is not due to screen wear (dryer fabrics, unlike forming fabrics and felts, are almost entirely rolling friction), but rather to screen hydrolysis caused by dirty or corroded dryer fabrics. To reduce the risk of hydrolysis, anti-hydrolysis agents are often added to the dryer fabric yarn to reduce this tendency.
