Polylactic Acid Fiber Performance And Product Development Research

Based on the study of the properties of PLA,Lyocell,Modal,Cashmere,hemp, bamboo,polynosic,cotton,and through the improvement of the technology,this paper resolved textile process problems caused by performance differences of tensile,elasticity, fineness of these fibers.The basic performances of the PLA / cashmere/Modal blended knitted fabric also were introduced in this paper Testing standards are mechanical properties,tensile,tear,to break drape,wear resistance,pilling property and bending property.The main indicators include tensile curve,tensile strength,elongation at break,tear curve,tear strength, bursting strength,trailer coefficient,bending length indicators,and so on.Comparative testing of blended knitted fabrics woven by different yarns,to study the wear ability of the PLA / cashmere / Modal blended knitted fabric.The results show that PLA / cashmere / Modal blended knitted fabric have the high tensile,poor wear resistance, excellent drape property and the poorest bending rigidity.The busting strength of PLA / cashmere / Modal blended knitted fabric lies between PLA /Modal/ cotton blended knitted fabric and PLA / Tencel/cotton blended knitted fabric.Pilling property is slightly better comparing with other fabrics.
