Spinning Blends.

Microfiber yarns improve the appearance, softness, and drape of woven fabrics. The manufacture of microdenier fibers requires highly selected polymerization, polymers, and extrusion methods. Unconventional spinning technologies can produce microfilament yarns at a high rate, partially offsetting their higher costs. An overview of how to s..

A Complete Range of Spinning Machinery.

Lakshmi Machine Works Limited's new Vario Clean Model LB9 cleaner increases the efficiency of blowroom operations and removes microdust to enhance yarn appearance. It handles all varieties of cotton gently and has minimal power consumption and space requirements. The company's LC300 carding machine provides excellent carding and cleaning ..

Short Staple Spinning on the Way to New Yarn Structures and Better Raw Material Utilisation.

An overview of developments in spinning techniques and machinery shown at ITMA 1999 describes fiber preparation to sliver; drawing and roving machines; and compact, vortex, and rotor spinning processes. Key developments included Barco's retrofitted fiber monitoring system that uses CCD cameras; Trutzschler's trash removal system, which is..

Product and Process Benchmarks for World-Class Cotton Yarn Manufacturing

Quickspin-method - a praxis-proved method for qualification of raw material

The raw material in the spinning mill causes the main part of costs at yarn production. According to spinning method and yarn count, more than 50% of the costs for yarn production are caused by raw material costs. For this reason the raw material is the reason the raw material is the essential feature with regard to an economical operatio..

The future of spinning and weaving (German)

The most important development trends in yarn and woven fabric production are demonstrated. Beginning with the basic technological conditions which alone have mainly made possible the textile industry's performance, compact spinning, pre-wetting in sizing and wave shed weaving in particular are treated. Finally comes a brief illustration ..

Swiss textile machinery in the spinning sector (Serbocroatian) (Svajcarska tekstilna masinogradnja u oblasti predenja)

The textile machinery production gives Switzerland a powerful role on the world textile machinery scene. With their new attitudes to the manufacturing processes and the business organisation, the Swiss textile machinery producers substituted the earlier goal 'production' for the new goal 'profit'. This way Switzerland has been able to com..

Barre and the Influences of Yarn Manufacturing

Influence of test speed on tensile characteristics of yarn

It is found that the breaking force increases with all staple fibre yarn, with an increasing testing speed. This increase depends primarily on the type of fibre and with blend yarns, on the percentage component of synthetic fibres. The breaking elongation can either increase or decrease with increasing testing speed. With elongation and w..

Yarn fineness, diameter, and twist

A new mathematical model for description of the relationship between yarn fineness twist and yarn diameter is presented. This model take into consideration the relationship between force and deformation due to fibre material compression, but on the other hand simplifies the problem so that the results can be easily applied in practice. A ..
