Weft feeders

fabric weaving Weft feeders are feeding devices, which are also called weft storage feeders or weft accumulators, play an important role in the weaving machines where the weft is unwound overhead from the cone and is subjected to abrupt accelerations due to the drawing-off tension exerted by the insertion element. The balloon which is formed at each insertion can cause coil sliding and snarls, owing to the difficulty of braking adequately the yarn and to the high unwinding speed of the yarn from the cone.

Shedding machines

fabric weaving The angle which is formed by the raising threads with the threads remaining in low position is called shed. The shed must be as wide open as to permit the easy passage of the weft insertion element. The shed can be obtained by either moving the heald frames or by directly moving the heald frames through. The machines used to form the shed are cam machines, dobbies and Jacquard machines.

Hair Fibers

fiber Hair fibers obtained from different kinds of animals also contribute to the fabric formation such as Musk-Ox (Qiviut), Alpaca, Mohair, Cashmere, Camel etc.

Water Proof and Water Repellent Finishes

finishing under-garments Fabrics to be used as raincoats, umbrellas, and tarpaulins have to be treated with chemicals to give them a property which makes them water resistant. The finish is called waterproofing and it is a durable finish. Water repellant finish is different from water proof finish. It means water, if showered on the fabric briefly, cannot make the fabric wet.

Sheep/Merino Wool Fibers

fiber Wool, common name applied to the soft, curly fibers obtained chiefly from the fleece of domesticated sheep, and used extensively in textile manufacturing.

Characteristics of Textile Blended yarn and fabric

yarn characteristics of textile blended yarns like- shrinks or not, water absorbent , has creases or not, has luster or not, soft/hard. Each kind of fibre has its own characteristics, when mixing them, one should consider their characteristics to create a hybrid with the characteristics needed.

Acrylic Fibres

fiber Acrylic fibres are polymers formed by addition polymerization of at least 85% by weight of a chemical called acrylonitrile or vinyl chanide. To polymerise vinyl cyanide the double bond between the first two carbon atoms is broken and the molecules attach themselves to each other in a linear chain.

Special Garment Finishes

apparel finishing There are finishes done on garments such as Permanent Press Finish particularly on pants for center crease of the pants to stay crisp and make them look fresh and neat.

Feeding Systems

apparel Material feed is the controlled movement of the material being sewn from one stitch position to the next. Different feeding mechanisms available are for sewing fabrics. Some of them are Manual feed, Feed dog, Drop feed, Needle Feed (Upper pivot needle Feed, Central pivot needle Feed, Parallel drive needle Feed), Wheel feed, Rotary feed, Upper Feed(Vibrating Presser Foot, Alternating Presser Foot, Top Feed, Jump Foot, Walking Foot, Spring action asking Foot, Driven walking Foot, Wheel feed.

Knitting

fabric knitting Knitting is a method by which thread or yarn may be turned into cloth. Knitting consists of consecutive loops, called stitches. As each row progresses, a new loop is pulled through an existing loop. The active stitches are held on a needle until another loop can be passed through them. Basically there are two types of knitting which are weft knitting, versus wrap knitting and another type is flat knitting versus circular knitting.
