"Silk and yarn composite sewing thread" is made by spinning PTFE monofilament and PPS, MPPS, aramid, PI and other fibers through coating, plying or double plying and other processes.On the premise of good sewing applicability, it has the following special functions:
1) Strong complementarity: PTFE has greater thermal creep properties. Tests have proven that: at a certain temperature, PTFE sewing Lines may experience strong attenuation or even failure.In this product, the composite yarn material has different heating properties from PTFE. The yarn can better compensate for the change in strength of the PTFE monofilament due to thermal creep, thereby avoiding damage to the filter bag and falling bags. risk.
2) Increased friction coefficient: The surface of the composite seam has a certain roughness due to the yarn. Since it has a higher friction coefficient than the pure PTFE thread, it can form a good fit with the filter material. Good attachment effect.
3) Increased surface wear resistance: The yarn-coated composite structure protects the outer layer of the sewing thread strands and increases the wear resistance of the sewing thread.4) Improve the blocking effect of the filter bag pinholes: The hairiness formed on the surface of the composite thread will firmly adhere to the filter bag after the filter bag is sewn, and the dust intercepted by the hairiness will easily form dust cakes in the pinholes to block the pinholes, thereby blocking the pinholes. Improve the filtration efficiency of filter bags.At the same time, it can also reduce the increased labor cost of applying film or glue to seal the pinholes of the filter bag.
