Knitted fabrics and woven fabrics difference Knitted fabrics and woven fabrics due to the different methods in the weaving, in the processing technology, fabric structure, fabric characteristics, finished product use, have their own unique characteristics, here for some comparison.
(A) the composition of the fabric organization: (1) Knitted fabrics: is the order of the yarn bent into a coil, and the coil string each other and the formation of fabrics, and the process of the formation of the coil of yarn, can be transverse or longitudinal, transverse knitting known as weft knitting fabrics, and longitudinal knitting known as warp knitting fabrics. (2) Woven fabrics: two or more groups of perpendicular to each other by two or more sets of yarns, at an angle of 90 degrees for the warp and weft interwoven fabrics, longitudinal yarns called warp, transverse yarns called weft.
(B) The basic unit of fabric organization: (1) Knitted fabrics: the coil is the smallest basic unit of knitted fabrics, and the coil is composed of a spatial curve by the loop stem and extension line. (2) Woven fabrics: each intersection point between warp and weft yarns is called the organization point, which is the smallest basic unit of woven fabrics.
(C) fabric organization characteristics: (1) knitted fabrics: because the coil is the yarn bent in space, and each coil consists of a yarn, when the knitted fabric by external tension, such as longitudinal tension, the coil of the bend changes, and the height of the coil increases, while the width of the coil decreases, such as the tension is the transverse tension, the situation is reversed, the height and width of the coil under different tension conditions, obviously can be The height and width of the loop can obviously be converted to each other under different tensions, so the elongation of the knitted fabric is large. (2) Woven fabrics: because the warp yarns and weft yarns intertwined with some bending, and only in the direction perpendicular to the plane of the fabric bending, the degree of bending and the warp and weft yarns and the mutual tension, as well as yarn stiffness related to the fabric, when the woven fabrics subject to external tension, such as longitudinal stretch, the tension of the warp yarns to increase the bending is reduced, and the weft yarns of the bending increases, such as longitudinal stretching, until the warp yarns are completely straightened out until the fabric is transversely contracted at the same time. The fabric is contracted transversely. When the woven fabric is stretched horizontally by external tension, the tension of the weft yarns increases, the bending decreases, and the bending of the warp yarns increases, such as stretching horizontally until the weft yarns are completely straightened, while the fabric shrinks in the longitudinal direction. The warp and weft yarns will not be converted, unlike knitted fabrics.
(D) The characteristics of the fabric organization: (1) Knitted fabrics: can be extended in all directions, good elasticity, because the knitted fabric is formed by the hole-like coil, there is a greater air permeability, feel loose. (2) Woven fabrics: because of woven fabrics warp, weft yarn extension and contraction relationship is not large, also does not occur conversion, so the fabric is generally more compact, quite hard.
(E) the physical and mechanical properties of the fabric organization: (1) Knitted fabrics: the physical and mechanical properties of the fabric, including longitudinal density, transverse density, square meters of grams, extensibility, elasticity, breaking strength, abrasion resistance, crimp, thickness, disintegration, shrinkage, coverage, bulk density. (2) Woven fabrics: physical and mechanical properties of woven fabrics, including yarn density of warp and weft yarns, fabric edge, front and back, direction of reverse hair, fabric coverage.
