Preparing for Change.

An overview of future yarn preparation processes and machinery addresses opening, carding, combing, drawing, and roving. With current production rates of 1,200 kilograms per hour, future developments in bale opening systems will focus on improving quality with fine particle cleaning devices and automated foreign material detectors. Cardin..

Spinning Mills : Challenges, Threats and Opportunities.

Spinning mills in India will face challenges, threats, and opportunities when markets fully open in 2005. The spinning industry must upgrade obsolete machines and increase the activity of unused spindles. Profitability dropped to 2 percent of national sales in the early 1990s, discouraging modernization and leading to poor quality yarns. ..

Production of Fault-Free World Class Yarns from Indian Cottons Using Modern Spinning Technologies.

The disadvantages of Indian cotton fibers, such as their greater weakness and higher levels of contamination, impede the ability of Indian yarns to meet export quality standards. Spinning mills should select cotton in the fields, supervise ginning, and use ultraviolet light testing prior to blowroom processing to reduce cotton contaminati..

Splicing of Rotor and Air-Jet Spun Yarns compared with Ring Yarns Compared with Ring Yarns.

Researchers assessed the retained splice strength (RSS) and retained splice extension (RSE) for pneumatically spliced cotton and cotton blend ring spun, air jet spun, and rotor spun yarns. The breaking strength and elongation of the spliced yarns were less than that of the unspliced yarns. Both cotton and cotton blend ring spun spliced ya..

Modern, Sophisticated Spinning Techniques.

An overview of new developments and trends in spinning technology include the G33 and XLA30 ring spinning machines. The G33 ring spinning machine modifies the cross section of the nose bar of the apron to improve fiber speed control and uses a SERVOgrip system for automatic doffing without underwinding. The XLA30 ring spinning machine fea..

The Bench Mark of Quality, Fair Trade Practice and Total Customer Satisfaction.

Lakshmi Machine Works Limited, a leading textile machinery manufacturer in India, supplies 60 percent of the domestic market. In addition to manufacturing a complete range of spinning machinery at economical prices, Lakshmi Machine Works has introduced machines to improve blowroom, carding, and combing performance. The Vario Clean Model L..

Automatic Processing on Spinning Machines.

The decision to automate spinning machines depends on a range of factors, particularly labor costs and the logistics involved in installation. A review of the components required for rational automation focuses on products from Zinser and describes a roving machine with an automatic doffer, its drive concept, the Ro-We-Mat 670 roving mach..

Process Rationalization by Integration of the Carding and Drafting Operation.

The integrated drawframe (IDF) used in conjunction with the Trutzschler DK 903 carding machine replaces at least one conventional drafting passage. Production lines that use two drafting passages during either ring or rotor spinning or up to three drafting passages during air jet spinning can eliminate the first breaker passage without th..

Successful Combination: RSB-D 30 Sliver and R 20 Rotor Spun Yarn.

Rieter Textile Systems' RSB-D 30 drawing machine improves weight uniformity in slivers and rotor spun yarns manufactured from these slivers, particularly short fiber yarns. An automatic control system in the unit is critical to achieving high quality yarn independent of fiber type or processing speeds. The system involves detecting and co..

Advantages of Condensed Spinning.

An introduction to condensed spinning methods for staple fibers reviews the condensed spinning process, structure and properties of condensed yarns, and their processing, including winding, doubling, sizing, weaving, knitting, and warp knitting. The condensed spinning process condenses the fiber strand prior to twist insertion, eliminatin..
