Development and performance evaluation of ultra-high dimensional stability polyester dipped cord fabrics
By increasing the number of spinneret holes,improving the setting temperature and spinning speed,high dimensional stability high modulus low shrinkage (HMLS) polyester industrial yarns with specification of 930 dtex were prepared with high viscosity polyethylene terephthalate chips. Then through weaving and dipping,the products of ultra-high dimensional stability polyester dipped cord fabrics were prepared,and the physical properties,modulus retention,creep performance,and high-temperature resistance were compared with those of conventional polyester dipped cord fabrics. The research results showed that compared with conventional polyester dipped cord fabrics of the same specification,the strength index of ultra-high dimensional stability polyester dipped cord fabrics was similar,the dimensional stability was improved by 29％,and the creep rate at 120 ℃ was reduced by about 20％. In addition,the product also demonstrated excellent modulus retention and high-temperature dimensional stability,which can effectively achieve the purpose of reducing tire rolling resistance.
