  • General knowledge of textile machinery

    Textile machinery is the natural or chemical fiber processing into a variety of machinery and equipment required for textiles. Although the production of chemical fiber machinery, including a variety of chemical machinery, is now considered an extension of the textile machinery, is a broad sense of textile machinery. Cotton, linen, silk, wool and other different fibers processed into textiles require different processes, some completely different, so the need for a variety of machines, a wide variety. Textile machinery is usually classified according to the production process, including: spinning equipment, weaving equipment, printing and dyeing equipment, finishing equipment, chemical fiber drawing equipment, reeling equipment and non-woven fabric equipment. Spinning equipment is further divided into two categories: processing short fibers and processing long fibers. Cotton and cotton-type chemical fiber is a short fiber class, wool, hemp, silk and its blend of chemical fiber is a long fiber class. The two types of fiber processing process is different, the equipment can not be common, but the design principles of certain machines are similar. Even if the same type of equipment, the structure of the machine is similar, but due to the nature of the raw materials and the final requirements of the fabric is different, generally can not be used.

    Weaving machinery is the spinning department made of yarn through the weaving preparation, weaving, finishing and other processes into the blank or finished cloth equipment. Weaving machine is the mutual vertical configuration of the two systems of warp and weft in accordance with a certain law stranded woven into the blank or finished cloth equipment. Looms have a variety of classification. According to the fabric fiber classification can be divided into cotton looms, wool looms, sack looms, silk looms, etc.. Such as the weaving method of weaving can be classified into two categories: shuttle looms and shuttleless looms. The shuttleless loom weft leading method is various, there are rapier, jet (air jet, water jet), piece shuttle, multi-shuttle mouth (multi-phase) and weaving and other ways.

    1, rapier loom: rigid or flexible rapier head, bring clamping, guide weft yarn. In addition to the rapier loom suitable for weaving plain and grain fabrics, its characteristics are convenient color change, suitable for multi-color weft fabrics, suitable for color weaving, double pile fabrics, terry fabrics and decorative fabrics production.

    2, air-jet loom: with the jet of compressed airflow on the weft yarn traction, the weft yarn with the shuttle mouth. Air jet loom is characterized by fast speed, high labor productivity, suitable for plain and patterned fabrics, fine special high-density fabrics and batch production of large fabrics.

    3, water jet loom: the use of water as a weft-led medium, to jet water to produce frictional traction on the weft yarn, so that the fixed cylinder on the weft yarn into the bobbin. The water jet loom is characterized by high speed and high unit output, and is mainly suitable for the production of hydrophobic filament chemical fiber fabrics with smooth surface.

    4、Sheet shuttle loom: The weft yarn is held by a small sheet shuttle with a clip and projected to lead the weft. Piece shuttle loom has the advantages of stable weft leading, excellent fabric quality and less weft return, which is suitable for the production of multi-color weft fabrics, fine and thick fabrics as well as wide fabrics.
