测试了针织泳衣面料的氨纶含量、拉伸弹性回复率及水中浮力，分析了氨纶含量与泳衣面料的弹性回复率及水中浮力之间的关系。
Tested the ammonia percentage of swimming suit fabric, its elastic recovery and buoyancy in water, and analyzed the relationship between ammonia percentage and the elastic recovery and buoyancy.
选择适当的温度和拉伸比进行热定形，可提高PTT织物的断裂强力和弹性回复率，但其延伸性变差。
The breaking strength and resilient-elasticity recovery of PTT fabric can be increased under suitable temperature and drawing ratio during heat setting, but its dilatability took worse.
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。
It is a severe shortcoming for traditional nonwovens that they have rather low elasticity and elastic recovery.
结果表明：随着填充油用量的增加，拉伸强度下降，弹性回复增加，断裂伸长率也增大。
The results indicated that with the increase of the content of the extender oil, the tensile strength decreased, while the elasticity increased and elongation at break improved.
