The cotton nylon blend stretch fabric is mainly bent by the yarn into a coil, and the coils are sleeved to form a fabric, and the process of forming the stitch of the yarn can be carried out laterally or vertically, and the transverse weaving is called weft-knitted fabric. And the longitudinal weaving is called a warp knit. Woven fabric: It is made up of two or more sets of mutually perpendicular yarns, which are interwoven with warp and weft at a 90 degree angle. The longitudinal yarn is called warp yarn, and the horizontal yarn is called weft yarn.
Tissue characteristics of cotton-knitted blended stretch fabric:
(1) Knitted fabric: Since the coil is a yarn which is bent in space, 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 coil is also increased, and the width of the coil is reduced. For example, the tension is transversely stretched, and the opposite is true. The height and width of the coil are obviously mutually convertible under different tension conditions, so that the stretchability of the knitted fabric is large.
(2) woven fabric: because the warp and weft are interlaced with some curvature, and the crepe is bent in a direction perpendicular to the plane of the fabric, the degree of bending and the mutual tension between the warp and weft, as well as the yarn stiffness, when the woven fabric is affected External tension, such as stretching in the longitudinal direction, increases the tension of the warp, and the bending decreases, while the bending of the weft increases, such as longitudinal stretching, until the warp is completely straightened, while the fabric shrinks laterally. When the woven fabric is stretched in the transverse direction by the external tension, the tension of the weft yarn is increased, the bending is reduced, and the warp yarn bending is increased, such as the transverse stretching, until the weft yarn is completely straightened, and the fabric is longitudinally contracted. However, the weft yarn does not change, unlike the knitted fabric.
