A Study of the Tensile Properties for Poly(trimethylene terephthalate, PTT) 1×1 Rib Knitted fabrics

Poly(trimethylene terephthalate, PTT) 1×1리브 편성물의 신장특성에 관한 연구

The tensile properties of Poly(trimethylene terephthalate, PTT) $1{\times}1Rib$ knitted fabrics were experimentally studies, and the specimens has $1{\times}1$ rib stitched structure which are weft knitted fabrics with various lengths of loop. The $1{\times}1$ rib weft knitted fabric showed larger tensile linearity, tensile energy and tensile resilience in the direction of courses. The tensile properties increased with increasing the loop density in all directions, and perfectly increased with the course directions than the wale directions.
