The difference between knitted denim and woven denim


Firstly, from the point of view of dyeing, woven denim yarns require sizing, knitted denim yarns do not. In terms of raw material selection, knitted denim yarns have a relatively low twist and a high cotton content. In contrast, woven denim yarns have a higher twist and often have slightly lower cotton content.


If used for wefting or weaving on the machine, knitted denim yarn can be used for woven fabric, but woven denim yarn cannot be used directly for knitting on the machine because the twist will cause twisting and surface faults. Even if the knitted fabric is barely woven, the twist will cause the overall weft slope to exceed the standard, which is not conducive to garment cutting and sewing. This can lead to serious twisting and other undesirable consequences.

Differences between woven and knitted fabrics:


I. The fabric's organizational structure


Knitting is made up of yarns bent into coils in order, and the coils are set in series to form a fabric. Woven is made up of two or more mutually perpendicular yarns, interwoven at an angle of 90 degrees for warp and weft. The longitudinal yarns are called transverse warp yarns are called weft yarns.


II. Physical and mechanical properties


Knitted fabrics' physical and mechanical properties are very good, including longitudinal density, transverse density, square meter grammage, elongation, elasticity, breaking strength, coverage, bulk density. The physical and mechanical properties of woven fabrics include only the yarn density of warp and weft yarns, fabric edges, front and back, cis-trans wool direction, and fabric coverage.


III. The basic unit of fabric organization


The smallest unit of a knitted fabric is the loop. The loop is made up of the loop stem and the extension line in a spatial curve. The smallest unit of a woven fabric is the organization's point, i.e., every intersection between warp and weft yarns.


Knitting is the process by which yarns form loops, which can be done horizontally or vertically; flat knitting is called weft knitting, and vertical knitting is called warp knitting. Knitting is divided into two categories: hand knitting and machine knitting. Hand knitting using stick needles has a long history of skillful, flexible, and varied patterns and has been widely passed down and developed in folklore.
