The difference between woven and knitted
Woven is a structure in which a shuttle is used to drive a weft yarn to pass through a warp yarn opening that is opened and closed at the top and bottom, and a yarn and a yarn are formed to intersect. Woven is a distinction that is different from knitting.
Woven is a fabric in which two or more sets of mutually perpendicular yarns are interlaced at a 90 degree angle.
Where the warp and weft yarns are intertwined, and they are only 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 woven fabric is subjected to external tension, such as in the longitudinal direction. When stretched, 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, while 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.
Because of the woven fabric, the weft extension and shrinkage have little relationship, and no conversion occurs. Therefore, the fabric is generally compact and quite hard.
Woven fabric: The physical and mechanical properties of the woven fabric, including the yarn density of the warp and weft, the hem, the front and back, the reverse wool direction, and the fabric coverage.
Classification of woven fabrics: 1, according to the composition of the tissue can be divided: cotton fabrics, silk fabrics, wool fabrics, hemp fabrics, chemical fiber fabrics and their blends and fabrics.
Organized into: plain, twill, satin. Each point of intersection between the warp and weft yarns is called the tissue point and is the smallest basic unit of the woven fabric.
The process of forming a loop of various raw materials and varieties of yarns by using knitting needles and then connecting them into a knitted fabric through a string. Knitted material is soft, has good wrinkle resistance and breathability, and has greater extensibility and elasticity, and is comfortable to wear. In addition to being used for decoration and decoration, knitted products can also be used in the fields of industry and agriculture as well as health care and national defense. 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.
Process characteristics
According to different process characteristics, 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. The stitches formed by the same yarn are arranged along the weft direction in the weft knitted fabric, and in the warp knitted fabric along the warp direction.
In 2010, China's macro economy continued to pick up. As domestic employment conditions stabilized, market confidence improved, residents' living standards continued to rise, and market demand for clothing-based consumer goods will maintain steady growth. At the same time, the national expansion of domestic demand plans continue to advance, in order to further improve people's livelihood, the state's investment in the construction of rural areas, affordable housing, and promotion of automobile consumption will continue to increase, which provides a broader range of home textiles and industrial textiles. Market space.
