Knitwear and woven fabrics are different. Knitted fabrics and woven fabrics have their own unique characteristics in the processing technology, fabric structure, fabric characteristics, and finished products. Because of their different methods in weaving, some comparisons are made here. The structure of the woven fabric: knitted fabric: the yarn is sequentially bent into a coil, and the coils are sleeved to form a fabric, and the process of forming the stitch of the yarn can be performed laterally or vertically, and the transverse weaving is called a weft woven fabric, and Longitudinal weaving is called 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. The fabric is basically a single knitted fabric: the coil is the smallest basic unit of the knitted fabric, and the coil is composed of a circle and a stretched line in a spatial curve. Woven fabric: Each point of intersection between warp and weft is called the tissue point and is the smallest basic unit of the woven fabric. Fabric texture characteristics 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. Woven fabric: the warp and weft yarns are somewhat curved, and the weir is bent in a 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 yarn stiffness. When the shuttle fabric is subjected to external tension, For example, when stretching in the longitudinal direction, the tension of the warp yarn is increased, the bending is reduced, and the bending of the weft yarn is increased, such as longitudinal stretching, until the warp yarn is completely straightened, and the fabric is laterally shrunk.
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. Knitted fabric of fabric structure: It can be extended in all directions, and the elasticity is good. Because the knitted fabric is formed by the hole-shaped coil, it has a large air permeability, and the hand feels soft and woven fabric: due to the woven fabric, the weft extension and contraction have little relationship. There is no conversion, so the fabric is generally tight and quite stiff. Physical and mechanical knit fabric of fabric structure: physical and mechanical properties of fabric, including longitudinal density, transverse density, square gram weight, elongation properties, elasticity, breaking strength, wear resistance, curling, thickness, dispersibility, shrinkage Sex, coverage, bulk density. The physical and mechanical properties of the shuttle fabric woven fabric, including the yarn density of the warp and weft yarns, the hem, the front and back sides, the reverse wool direction, and the fabric coverage.
