What is the difference between woven and knitted fabrics

 Knitted cloth is a fabric formed by using knitting needles to bend yarns into loops and string each other. It is mainly divided into two categories: circular woven and flat woven fabrics (also known as warp knitted fabrics and weft knitted fabrics). Woven cloth is what we often call woven cloth. It is a fabric made of two or more groups of perpendicular yarns interlaced at a 90-degree angle to warp and weft. The longitudinal yarns are called warp yarns and the transverse yarns are called weft yarns.

Knitted fabric is formed by bending the yarn in space, and each loop is composed of a single yarn. When the knitted fabric is subjected to external tension, such as longitudinal stretching, the bending of the loop changes, and the height of the loop increases. At the same time, the width of the loop is reduced. If the tension is laterally stretched, the situation is the opposite. The height and width of the loop can obviously be switched under different tension conditions, so the knitting fabric has a large stretchability.

The woven fabric is slightly bent where the warp and weft interweave, and it bends 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 and the stiffness of the yarn. When the woven fabric is subjected to external tension, such as When stretched in the longitudinal direction, the tension of the warp yarn is increased, and the bending is reduced, while the weft yarn is increased, such as continuous stretching in the longitudinal direction until the warp yarn is completely straightened, and the fabric is contracted transversely. When the woven fabric is stretched laterally by external tension, the tension of the weft yarn increases, the bending decreases, and the warp warp increases, such as the lateral stretching is continued until the weft yarn is fully straightened, and the fabric shrinks longitudinally. Warp and weft yarns do not change, unlike knitted fabrics.

There are two types of knitting: hand knitting and machine knitting. Hand-knitting uses stick needles. It has a long history, exquisite craftsmanship, and flexible flower shapes. It has been widely spread and developed in folk. Knitting production is divided into two categories: weft knitting and warp knitting. In weft-knitting production, the package yarn can be directly produced on the machine after the raw material is winded. Each yarn is sequentially laid on the knitting needles of the weft knitting machine in the weft direction to form a weft knitted fabric. In warp knitting production, the raw materials go through the winding and warping, and the yarns are arranged in parallel and wound into warp beams, and then produced on the machine. The yarn is unwound from the warp beam, and each yarn is individually cushioned on one or at most two knitting needles of the warp knitting machine in the longitudinal direction to form a warp knitted fabric. There are also methods of combining weft and warp knitting on some knitting machines. At this time, two sets of yarns are arranged on the knitting machine, one is set according to the warp knitting method, and the other is set according to the weft knitting method. The knitting needles form the two sets of yarns together to form a knitted fabric. Weaving (weaving) can also be called "weaving", using yarn as warp and weft to form woven fabrics according to various fabric structures. Is an important part of the textile industry production. According to the type of raw materials used, it can be divided into cotton, wool, silk and linen, and their products are collectively referred to as woven fabrics. Woven fabrics have a wide variety of uses and applications. According to different requirements, select the appropriate yarn raw materials and appropriate fabric structure.
