本发明提供一种热收缩率低、热尺寸安定性佳的网状构造体。;上述网状构造体系使由热可塑性弹性体所构成的纤度为100十特克斯(decitex)以上60000十特克斯以下的连续线状体卷曲形成不规则环(random loop)，使各环互相以熔融状态接触之三维不规则环接合构造体，且表观密度为0.005g/cm 3 ~0.20g/cm 3 ，130℃乾热收缩率为1.5%以下。 Provided is a reticular structure with excellent thermo-dimensional stability and small heat shrinkage percentage. The reticular structure is made by curling a continual linear body of a thermoplastic elastomer with a fineness being not less than 100 decitex and not larger than 60000 decitex, so as to form random loops and to have individual loop contact with each other under a melting state in order to result in a three dimensional random loop jointing structure, of which the apparent density is within 0.005g/cm 3 ~ 0.20g/cm 3 and the dry heat shrinkage percentage at 130℃ |
