Variance Tolerancing and Decomposition in Short-Staple Spinning Processes -- Part II: Simulations and Applications to Ring and OE Spun Yarns.

Researchers applied a variance tolerancing and decomposition method from Part I to fiber and Yarn test data obtained over a three year period from a spinning mill. The method decomposed the variabilities of single end strengths occurring in six different ring spun and open end yarns into random and process induced variance components by t..

Solospun: Fiber Yarns for Lighter Fabrics at Lower Cost.

Fabric manufacturers in the Far East use Solospun yarns to manufacture light weight fabrics with improved hand. W.D.I., a division of the Woolmark Company, is the Kingdom. When installed on a conventional spinning machine, the spindle modifies the yarn structure to produce a weavable singles yarn with improved abrasion resistance. The res..

Challenges of the Global Textile Market: A View from Korea.

Combed cotton and blended yarn manufacturer Ilshin Spinning Company Limited of South Korea operates 196,000 spindles and manufactures 41,000 tons of yarn annually. The company has a yarn and knit fabric dyeing capacity of 35,000 kilograms per day. Company sales in 1999 were $230 million and net income after taxes was $30 million. The comp..

Sense and Senselessness of Textile Machine Exhibitions.

The ATME-I 2000 exhibition in Greenville, South Carolina, offered few significant developments in technology. A number of major manufacturers did not attend or presented down sized exhibits. Notable presentations included compact spinning machines, which use a rotating screening drum to collect fibers, and air jet (vortex) spinning machin..

Trends in Cotton Spinning Technology.

Rotor spinning, air jet spinning, friction spinning, compact spinning, and composite spinning offer higher production rates than conventional ring spinning while eliminating some processing stages, reducing labor and space requirements, and simplifying automation. Rotor spinning machines with 2,888 spinning positions spin yarns at take up..

Energy Control in Spinning Mills.

An energy audit of an Indian spinning mill with 45, 042 spindles operating primarily on high speed diesel power addressed such energy consumption sources as ring spinning machines, humidity control equipment, winding machines carding machines, blowroom machines, heating lamps, and lighting. Each machine was evaluated for method of power t..

Vacuum pyrolysis

Rieter Automatik is introducing new cleaning technology for the film, nonwovens and fibre spinning industries. The Solvo T vacuum pyrolysis cleaner is designed for a wide range of polymer-contaminated parts and tools. Because the whole process involves gasification, the interiors of complicated tools can be cleared without taking them apa..

A new methodology usable by researchers and spinners for short staple fiber microspinning

From this specific methodology developed by Cirad, the scientist is able to widen his investigation to variable quantities of cotton ranging from 50 to 500g. The choice of the amount of cotton will be induced by the cost of the study, the kind of information and the accuracy of the results to be obtained.

Benchmarking in cotton spinning by ISO 14 000

The European Community prepares a procedure for evaluation of environmental performance, called Best Available Technology (BAT) in companies. Restrictions due to environmental law are already as great that companies decline further mandatory requirements. Many of the companies are ready for proactive operations and implementation of an en..

Solving problems in spinning Part 17. Spinning of wool with linen (German)(Problemlosungen in der Spinnereipraxis Teil 17: Verspinnung von Wolle mit Leinen)

The spinning of linen in blends with other fibres, especially wool, can cause problems which are difficult to solve, even using modern material processing procedures and techniques. Since there is an increasing demand for linen in blends with other materials, this article discusses the problems that are likely to arise and ways of solving..
