(1) Knitted fabric: Because the coil is formed by bending yarn in space, and each coil is composed of one yarn, when the knitted fabric is subjected to external tension, such as longitudinal stretching, the bending of the coil changes, and the coil The height of the loop also increases, while the width of the loop decreases. If the tension is transverse stretching, the situation is reversed. The loop height and width are obviously interchangeable under different tension conditions, so the knitted fabric has great extensibility.
(2) Woven fabric: Because the place where the warp and weft yarns interweave is somewhat curved, and the weft bends in the direction perpendicular to the plane of the fabric, the degree of curvature is related to the mutual tension between the warp and weft yarns and the stiffness of the yarns. When the woven fabric is subjected to External tension, such as stretching in the longitudinal direction, increases the tension of the warp yarn and reduces the bending, while the bending of the weft yarn increases, such as longitudinal stretching, until the warp yarn is completely straightened, and the fabric shrinks horizontally. When the woven fabric is stretched horizontally by external tension, the tension of the weft increases, the bending decreases, and the bending of the warp increases. If the horizontal stretching continues, until the weft is completely straightened, the fabric shrinks longitudinally. The warp and weft yarns will not be converted, unlike knitted fabrics.
