Fiber tensile strength lower than the standard value
문제 현상
The fiber tensile strength is lower than the standard value and the mechanical properties do not meet the standard
원인 분석
（1）Insufficient draw ratio causes low molecular orientation degree
（2）The spinning temperature is too high and the crystallinity is inappropriate
（3）Improper cooling rate causes poor crystalline structure
（4）Raw material moisture affects the molecular chain connection
（5）Improper additive formulation
해결 방법
（1）Appropriately increase the draw ratio to increase orientation
（2）Optimize the spinning temperature to control the crystallinity
（3）Adjust the cooling rate
（4）Fully dry the raw material
（5）Optimize the additive formulation
핵심 요약
Fiber strength needs to be addressed from orientation, crystallization, and formulation
