聚乳酸(玉米)混纺纱强伸性与混纺比之间的关系

The relationship between tensile properties and blend ratio of PLA/Modal blended yarn

研究了不同混纺比聚乳酸/莫代尔混纺纱的力学性能变化特点.得出了聚乳酸/莫代尔混纺纱断裂强力在聚乳酸含量为70%左右时达到最小值,而断裂伸长率和断裂功在聚乳酸含量为70%时有着显著增大,初始模量在聚乳酸含量达到40%时有明显减小.

The tensile properties and different blended ration of PLA/Modal yarn were ananyzed.The results show that when PLA content of 70%,the breaking strength of PLA/Modal blended yarn reaches the minimum,the elongation at break and work of break increase obviously.The initial modulus decrease when PLA content of 40%.
