A Guide to Textile and Clothing
Clothing is divided into different categories depending on which part of the body we wear and for which purpose they serve, such as casual wear, innerwear, outerwear, etc. Not only for going outside, but the clothes we wear on the outer part of our body to add a little style or prevent winter cold are[…]
A polymer is like a giant molecule of small building blocks called monomers. These monomers are tiny organic compounds. They form a long chain or network when they come together through a chemical process called polymerization. This can happen in different ways, like addition polymerization, where the monomers join without producing any extra stuff, or[…]
Main Features of Flocked Fabrics A surface effect that is similar to a nap or a pile may be created by flocking, a process in which short fibres are “glued” onto the surface of fabrics by an adhesive material. If the adhesive coats the entire surface of the fabric, the flocking will cover the entire[…]
Instead of buying any cotton available at the lowest price, spin it to produce yarn if highest count possible and selling yarn at any market at random. It is advisable to locate a good market where yarn can be sold at the highest price and fine cotton, which has characteristics to spin the yarn of desired specifications for that[…]
Weft Storage System – Drum Feeder The following figure shows the schematic diagram of a drum feeder for air-jet weaving machines. The weft yarn is drawn off the package and wound onto measuring band two by the rotating motion of yarn guiding tube 1. The pick length depends on the fabric width. The pick length[…]
Working Principle of Air Jet Loom Air jet weaving machines were invented in Czechoslovakia and later refined by the Swiss, Dutch, and Japanese were designed to retain the tension less aspect of the picking action of the water jet while eliminating the problems caused by the use of water. The yarn is pulled from the supply package[…]
Direct Counting Method The essence of the method is to unwind the twist in a yarn until the fibres are parallel to the yarn axis and to count how many turns are required to do his. A suitable instrument has two jaws at a set distance apart. One of the jaws is fixed and the other is capable of being rotated.[…]
Primary Motions In order to interlace warp and weft threads to produce fabric on any type of weaving machine, three operations are necessary: Shedding Separating the warp threads, which run down the fabric, into two layers to form a tunnel known as the shed. Picking Passing the weft thread, which traverses across the fabric, through the shed.[…]
Weaving and Woven Fabric In general terms, a textile fabric may be defined as an assembly of fibers, yarns or combinations of these. There are several ways to manufacture a fabric. Each manufacturing method is capable of producing a wide variety of fabric structures that depend on the raw materials used, equipment and machinery employed and the[…]
Definition of Hydrolysis Hydrolysis is a chemical process in which a molecule is cleaved into two parts by the addition of a molecule of water. One fragment of the parent molecule gains a hydrogen ion (H+) from the additional water molecule. The other group collects the remaining hydroxyl group (OH−). Hydrolysis of Reactive Dye During[…]
