Abstract: In this paper, eco-friendly knitted fabrics with good moisture absorption and draping property were developed in accordance with the characteristics of bio-based polyamide spun yarn. Bio-based polyamide spun yarn can meet the performance requirements of bio-polyamide fabric, which has excellent abrasion resistance, better draping and moisture permeability; it is an ideal apparel fabric. It will be the development direction of bio-based polyamide fiber to develop blended or interwoven knitted products by mixing bio-based polyamide fiber with other fibers, enrich product varieties and improve product performance.

Key words: bio-based polyamide; spun yarn; knitted fabric; performance
