摘　　要：以高黏度聚对苯二甲酸乙二醇酯切片为原料,通过增加喷丝板孔数、提高定型温度及纺丝速度等措施,制备规格为930 dtex的高尺寸稳定型高模低缩(HMLS)涤纶工业丝,再经织造与浸胶工序,制备具有超高尺寸稳定型涤纶浸胶帘子布,并与常规涤纶浸胶帘子布在物理性能、模量保持率、蠕变性能以及耐高温性能等方面进行对比和分析。研究结果表明,相较于同规格的常规涤纶浸胶帘子布产品,超高尺寸稳定型涤纶浸胶帘子布的强力指标接近,尺寸稳定性提升29%,并且在120℃条件下的蠕变率降低约20%。此外,该产品展现出卓越的模量保持率和高温尺寸稳定性,能有效实现轮胎降低滚阻的目的。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.
