The Making Principle Of Cut Pile Fabric


    Pile fabrics are characterized by tufts or loops of fibers or yarns erected from the base fabric. Pile fabrics exist in many forms, such as velvet, terry cloth, chenille, and perhaps the most common are pile carpets. They can be made through a variety of processes, including tufting, knitting, knotting, flocking, and non-woven fabrics. It is believed that velvet fabrics existed as early as 2000 BC. The most common type of velvet is cut pile fabric, which is widely used in clothing and household products. The pile is produced by the extra set of warp yarns used in the weaving process. There are several production methods. One method is to perform thread weaving by inserting the thread into the shed formed by the warp yarn for the pile. The pile warp yarn forms a yarn loop on the surface of the fabric after the metal wire is pulled out. The pile can be left as loop pile or cut into cut pile. In the loop fabric, loops are formed on both sides of the fabric. Another method of producing pile fabrics is face-to-face knitting, where a double-layer fabric is made of vertical connections provided by an additional set of warp yarns. The connecting warp yarns are then cut to produce velvet piles. This is illustrated in Figure 14.4. Obviously, only cut pile fabrics can be manufactured in this way. It can also produce pile effect by knitting

    Another widely used pile fabric is tufted carpet. Tufting is accomplished by stitching the base fabric with a tufting needle to form a loop of yarn. The tufting needle passes the pile yarn through the base fabric. Then insert a curved needle between the yarn and the needle. The needle is retracted through the base cloth to start the next cycle, and at the same time a loop of pile is formed on the curved needle. The loops formed on the backing fabric can be cut or leave loops. The backing fabric is usually woven, but non-woven fabrics can also be used. Pile yarn is traditionally a spun yarn, especially wool, but bulky continuous filament yarn is increasingly used. Pile carpets can also be made by adhesive bonding and flocking. In the flocking process, short fibers cut from natural or synthetic fibers are laid on the surface of the fabric coated with adhesive; then the fabric is cured. Flocking fiber spreading can be done mechanically, or more commonly, using electrostatic force. In the electrostatic process, the electric field force helps to align the flocking fibers perpendicular to the fabric surface. The flocking process is faster and cheaper than other pile fabric production processes, but the durability of the pile may be relatively low because the anchoring of the pile fibers on the base fabric is limited and depends on the adhesive Bond strength. The improvement in quality has led to more and more flocked fabrics being used in apparel applications and technical applications such as insulation and high impact composite materials.
    The so-called cut pile fabric is made by turning pile fabric into short piles. In the case of dividing the line segments, the piles are formed. But such fabrics are very soft and elastic.
    It is very suitable to be used as a Decoration fabric.
