Fabric organization characteristics: (1) Knitted fabric: Because the loops are formed by bending the yarn in space, and each loop is composed of a yarn, when the knitted fabric is subjected to external tension, such as longitudinal stretching, the bending of the loop occurs Change, and the height of the loop increases, while the width of the loop decreases. If the tension is horizontal stretching, the situation is reversed. Under different tension conditions, the height and width of the loop can obviously be converted to each other, so the extension of the knitted fabric Sex.
(2) Woven fabric: Because the warp and weft interlace are somewhat bent, and the moraine is bent in the direction perpendicular to the plane of the fabric. The degree of bending is related to the mutual tension between the warp and weft yarns and the stiffness of the yarn. External tension, such as stretching in the longitudinal direction, the tension of the warp yarn increases, and the bending decreases, while the bending of the weft yarn increases, such as longitudinal stretching, until the warp yarn is fully straightened, and the fabric shrinks in the transverse direction. When the woven fabric is stretched transversely by external tension, the tension of the weft yarn increases, the bending decreases, and the warp yarn bending increases, such as the transverse stretching continues until the weft yarn is fully straightened, and the fabric shrinks longitudinally. The warp and weft will not change, which is different from knitted fabrics.
