Physical classification of Fibers

fiber Fibers are broadly classified into Filament yarns and Staple Yarns on the basis of their physical structure.Filament yarns are measured in yards or meters.

Blended Fiber Analysis

fiber Blended yarns usually offer the best of several worlds - the breathability of wool or cotton, the durability of acrylic or nylon. Blends take dye differently and offer different color effects as well.Fiber blending has has for a long time been practiced in textile processing. By mixing fibers of different types to form textile yarns , many advantages are achieved, such as property compensation or reinforcement between fibers, cost reduction without significant sacrifice of yarn performance by pa

Fiber Identification

fiber A number of methods are available for characterization of the structural, physical, and chemical properties of fibres. Various methods are used for fibre identification like microscopic methods, solubility, heating and burning method, density and staining etc. End-use property characterization methods often involve use of laboratory techniques which are adapted to simulate actual conditions of average wear on the textile or that can predict performance in end-use.

Microscopic appearance of Fibres

fiber Technical tests require skilled personnel who can handle and use the equipment and chemicals for the analysis of the textile fibres. Among microscopic tests and chemical tests, microscopic tests are mainly used for natural fibre. The test identifies the natural fibres more easily as compared to manmade ones. Synthetic fibres are very similar in appearance and the increase in the number of varieties makes it a little tough to distinguish the fibres even under a microscope. The longitudinal and c

History of Fibres

fiber Fibres have traditionally been used in all cultures of the world to meet basic requirements of clothing, storage, building material, and for items of daily use such as ropes and fishing nets.

Timeline of Manmade Fibers

fiber A useful filament was not produced until the last part of the 19th century, when Swann and de Chardonnet extruded a solution of cellulose nitrate (collodion) through small holes (spinnerets). These pioneer manmade fibres were replaced by rayon fibres which were spun from an alkaline cellulose xanthate solution (viscose), which were in turn supplemented by cellulose acetate and many synthetic fibres.

Natural Fibres

fiber All fibres which come from natural sources (animals, plants, etc.) and do not require fibre formation or reformation are classed as natural fibres. The natural fibres are vegetable, animal, or mineral in origin. Some of the natural fibres like vegetable fibres are obtained from the various parts of the plants. They are provided by nature in ready-made form. It include the protein fibres such as wool and silk, the cellulose fibres such as cotton and linen, and the mineral fibre asbestos.

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.

Properties of Vegetable/Plant/Cellulosic fibres
