Functions of Carding

spinning spun-yarn yarn Carding is a mechanical process that breaks up locks and unorganised clumps of fibre and then aligns the individual fibres so that they are more or less parallel with each other. Carding can also be used to create blends of different fibres or different colours. Carding plays a crucial role in all spinning cycles particularly in the woollen spinning cycle, in which it incorporates different functions, all essential in order to obtain the level of quality required of the product.

Acrylic the Artificial Wool Fibers

fiber Acrylic can be thought of as artificial wool. It is made from the unlikely combination of coal, air, water, oil and limestone.

Simplex Frame and its Parts

spinning spun-yarn yarn The chief function of simplex frame is the attenuation of sliver. Insertion of protective twist in order to hold the fine strand of sliver. Winding of roving into a package that can be transported, sorted, donned on ring spinning machine.After carding the cotton is passed through draw frames. The draw frame draws the cotton inot thick strands.These are then spun inot thinner strands on hte simplex frame spindles. The output of the simples frame is fed to the ring frame spindles which complete t

Polyamide Fibres

fiber The polyamide fibres include the nylons and the Aramid fibres. Both fibre types are formed from polymers of long-chain polyamides.

Parts of Loom

fabric weaving Weaving looms can range from quite simple to very complex. Looms have been used to produce cloth for thousands of years, and while technology has improved the loom, the basic strategies and practices remain much the same. Understanding the parts of the loom can help you learn to weave or simply learn a bit more about how weaving works.

Carton Strapping

apparel A wide variety of tool and machine systems are available to strap cartons, eventual choice often being determined by through put and/or cost. Generally the easiest way to strap cartons is with a semi automatic machine that has a cycle time per strap of just over 2.0 seconds. Automatic and automated machines are frequently used for continuous bulk usage. Polypropylene (PP) strapping is an economical packaging solution designed for light to medium duty unitizing, palletizing and bundling.

Natural Cellulose Fibres

fiber Cellulose is a fibrous material of plant origin and the basis of all natural and man-made cellulosic fibres. The natural cellulosic fibres include cotton, flax, hemp, jute, and ramie. Cellulose is a polymeric sugar polysaccharide) made up of repeating 1,4-8-an hydro glucose units connected to each other by 8-ether linkages. Strong intermolecular forces between chains, coupled with the high linearity of the cellulose molecule, account for the crystalline nature of cellulosic fibres.

Natural Protein Fibres

fiber The protein fibres are formed by natural animal sources through condensation of a-amino acids to form repeating polyamide units with various substituent on the a-carbon atom. In general, protein fibres are fibres of moderate strength, resiliency, and elasticity. They have excellent moisture absorbency and transport characteristics. They do not build up static charge. Example of some these fibres are Wool, Silk, Mohair, Cashmere etc.
