Manufacturing Techniques and Mechanical Properties of Recycle High-Strength PET Compound Nonwoven

Abstract

The high-strength polyester fiber is a kind of chemical fiber that is rapidly developed and widely applied. With development of technology, the demands for polyester fiber are becoming more and more. Furthermore, the high-strength polyester fiber, used to reinforce the matrix, has higher modulus and strength than commercial polyester fiber. In this research, the 15D polyester fiber, the low melting polyester and the high-strength polyester fiber were used to manufacture the high-strength PET compound nonwoven fabrics by nonwoven processing. Afterwards, the mechanical properties of the PET compound nonwoven was measured both at cross direction and machine direction.
