Abstract: In order to integrate the shape memory property of PTT with the excellent wearability of silk, this paper used silk spinning technology to manufacture PTT/spun silk blended yarn with blending ratio of 50:50, and using it as warp and weft designed 5 kinds of PTT/spun silk blended fabrics, in addition also weaved 3 kinds of pure spun silk fabric with the same specifications. Then tested the handle style characteristics, drape, shape preservation(wrinkle and tensile resilience), permeability(air and moisture) and pilling resistance of all the 8 fabrics. Through comparison and analysis of the style and wearing properties of pure spun silk fabric and PTT/spun silk blended fabric, the results shows that compared with pure spun silk fabric, PTT/spun silk blended fabrics’ wrinkle and tensile resilience improve, softness and drape also increase, but smoothness, permeability and pilling resistance decrease.

Key words: PTT, spun silk, blended spinning, style, wearing property
