负拉伸 meaning in Chinese

negative draft
negative stretch

The fiber tensile strength is affected by concentration , temperature and minus stretch during coagulation , while the fiber structure and performance are obviously in fluenced by stretch temperature , medium and ratio
纤维的拉伸强度在凝固成形过程中受到凝固浴浓度、温度和负拉伸的影响，同时在纤维的拉伸中拉伸的倍数、温度和介质等也影响著纤维的结构和性能。
