Heat treatment is optional after rubber mixing as to products of lowelasticity demand.
对回弹性要求不高的制品，炼胶后也可不作热处理。

It is a severe shortcoming for traditional nonwovens that they have rather lowelasticity and elastic recovery.
对于传统非织造材料，弹性差，经拉伸后回复率低是长期以来难以克服的一个缺点。

The point of inflection from lowelasticity region characteristics to high elasticity region characteristics in a stress-strain curve is preferably set in a range of 2 to 7 % of strain.
