In the production course of nonwovens fabric for water-proof substrate, the influence of process parameter such as punching depth, needle density, thermosetting time and temperature, etc to QC quality is introduced in the paper.Then come QA. It is proved that proper needle depth and deedle density are main factor to product strength. With the increase of needle depth, breaking elongation rate decreased. Product anti-shringkage depends on proper thermosetting time and temperature.
Be diligent in R&D, pursue excellence
The polyester fabric and its preparation method can solve the problems of uneven transverse and longitudinal tensile strength, poor elongation and poor high temperature performance of the existing polyester tire. It can effectively avoid the problem of impermeability or non-drying in the production process of copolymer waterproof membrane, thus ensuring the optimal high temperature performance of the final product.
