What is the difference between woven and knitted fabrics?

What is the difference between woven and knitted fabrics? A knitted fabric is a fabric formed by bending a yarn into a loop by a knitting needle and staking them together. Mainly divided into two categories: round and flat woven fabrics, (or called warp knitted fabrics and weft knitted fabrics). Woven fabrics are also the weaving fabrics we often say. 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 knitted fabric is formed by bending the yarn in the space, and 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 height of the coil is also increased. At the same time, 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;

The woven fabric is somewhat curved due to the interlacing of the warp yarn and the weft yarn, 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 yarns, as well as the yarn stiffness, when the woven fabric is subjected to external tension, such as When stretched in the longitudinal direction, the tension of the warp yarn increases, the bending decreases, and the bending of the weft yarn increases, such as longitudinal stretching, until the warp yarn is completely straightened, and 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.

Knitting is divided into two categories: hand knitting and machine knitting. Hand-knitted needles have a long history, exquisite craftsmanship, flexible flower shapes, and have been widely spread and developed in the private sector. Knitting production is divided into two categories: weft knitting and warp knitting. In the production of weft knitting, the yarn can be directly produced on the machine after the raw material is passed through the winding. Each of the yarns is sequentially placed in the weft direction on each of the knitting needles of the weft knitting machine to form a weft knitted fabric. In the warp knitting production, the raw materials are subjected to winding and warping, and the yarns are arranged in parallel to be wound into a warp beam, and then produced on the machine. The yarn is retracted from the warp beam, and each of the yarns is placed on one or at most two knitting needles of the warp knitting machine in the longitudinal direction to form a warp knit. There are also methods for combining weft knitting and warp knitting on some knitting machines. At this time, two sets of yarns are arranged on the knitting machine, one set is padded according to the warp knitting method, and the other set is laid by the weft knitting method, and the knitting needles form the stitches together to form a knitted fabric. Weaving, which can also be called "woven", is a process in which woven fabrics are formed by warp and weft according to various fabric structures. It is an important part of the textile industry. According to the type of raw materials used, it can be divided into cotton, wool, silk and hemp. The products are collectively referred to as woven fabrics. The variety and use of woven fabrics are extremely wide, and suitable yarn materials and suitable fabric structures are selected according to different use requirements.
