Yarn Clearer
A yarn clearer is a device to remove faults (thick places, thin places, foreign matter) from the yarn. Yarn clearing improves the quality of the spun yarn and hence of the cloth made of it. Clear, uniform yarn is especially important for smooth operation of high-speed textile machinery. Yarn clearing is usually part of the yarn winding step. The yarn from a number of spinning bobbins, called 'cops', is wound on to larger packages called 'cones' for subsequent processing into fabric. During the winding the yarn was traditionally passed through the narrow slit in a steel plate of a yarn clearer or slub-catcher. The object was to catch thick places, or slubs, which occurred when the spinning process suffered an aberration, and to prevent them being woven into the fabric to present unsightly faults. In modern textile industry The textile industry is primarily concerned with the design, production and distribution of yarn, cloth and clothing. The raw material may be natural, or ...

Yarn
Yarn is a long continuous length of interlocked fibres, used in sewing, crocheting, knitting, weaving, embroidery, ropemaking, and the production of textiles. Thread is a type of yarn intended for sewing by hand or machine. Modern manufactured sewing threads may be finished with wax or other lubricants to withstand the stresses involved in sewing. Embroidery threads are yarns specifically designed for needlework. Yarn can be made of a number of natural or synthetic materials, and comes in a variety of colors and thicknesses (referred to as "weights"). Although yarn may be dyed different colours, most yarns are solid coloured with a uniform hue. Etymology The word yarn comes from Middle English, from the Old English ''gearn'', akin to Old High German ''garn'', "yarn," Dutch "garen," Italian ''chordē'', "string," and Sanskrit ''hira'', "band." History The human production of yarn is known to have existed since the Stone Age and earlier prehistory, with ancient fiber mat ...

Spinning (textiles)
Spinning is a twisting technique to form yarn from fibers. The fiber intended is drawn out, twisted, and wound onto a bobbin. A few popular fibers that are spun into yarn other than cotton, which is the most popular, are viscose (the most common form of rayon), and synthetic polyester. Originally done by hand using a spindle whorl, starting in the 500s AD the spinning wheel became the predominant spinning tool across Asia and Europe. The spinning jenny and spinning mule, invented in the late 1700s, made mechanical spinning far more efficient than spinning by hand, and especially made cotton manufacturing one of the most important industries of the Industrial Revolution. Process The yarn issuing from the drafting rollers passes through a thread-guide, round a Ring spinning#How it works, traveller that is free to rotate around a ring, and then onto a tube or bobbin, which is carried on to a Spindle (textiles), spindle, the axis of which passes through a center of the ring. The spin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bobbin
A bobbin or spool is a spindle or cylinder, with or without flanges, on which yarn, thread, wire, tape or film is wound. Bobbins are typically found in industrial textile machinery, as well as in sewing machines, fishing reels, tape measures, film rolls, cassette tapes, within electronic and electrical equipment, and for various other applications. Industrial textiles Bobbins are used in spinning, weaving, knitting, sewing, and lacemaking. In these practices, bobbins were invented to "manage the piles of thread and yarn that would be mechanically woven into cloth," where the mechanical began using human power, but eventual became machine-driven. In these applications, bobbins provide storage, temporary and permanent, for yarn or thread. Historically, bobbins were made out of natural materials such as wood, or bone. While not in principle an invention of the Victorian era—bobbins in the production of textiles were in earlier use—the machinery introduced in that e ...

Slub (textiles)
A slub in textiles production refers to thickened areas of a fiber or yarn. Slubbed or slubby fabric is woven from slubby yarn (yarn with a very variable diameter). Both high and low slubbiness may be sought. Slubs in spun fibers may be produced deliberately by varying spinning tension (see Novelty yarns#Slub). They are also produced when short, staple fibers are spun into a single yarn. Slubs may be valued or deliberately produced for aesthetic effect, but they may also be regarded as a defect caused by either uneven spinning or using low-grade, lumpy or short-staple fiber. Types Slubby cotton fabric includes: *Madras (cloth), woven from short-staple cotton *Some denim used for jeans; the slubs cause the cloth to fade unevenly, in a pattern called Linen is often slubbed. Wool fabrics, such as tweeds, may also be slubbed. Silk is a filament fiber, and the only natural fiber type to come in filament length naturally (strands can be over 1.5 km long). However, some silk f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Textile Industry
The textile industry is primarily concerned with the design, production and distribution of yarn, cloth and clothing. The raw material may be natural, or synthetic using products of the chemical industry. Industry process Cotton manufacturing Cotton is the world's most important natural fibre. In the year 2007, the global yield was 25 million tons from 35 million hectares cultivated in more than 50 countries. There are five stages of cotton manufacturing: * Cultivating and Harvesting * Preparatory Processes * Spinning — giving yarn * Weaving — giving fabrics * Finishing — giving textiles Synthetic fibres Artificial fibres can be made by extruding a polymer, through a spinneret (polymers) into a medium where it hardens. Wet spinning (rayon) uses a coagulating medium. In dry spinning (acetate and triacetate), the polymer is contained in a solvent that evaporates in the heated exit chamber. In melt spinning (nylons and polyesters) the extruded polymer is cooled in gas or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
