Irregularity of Fibre Slivers in Drafting on Worsted Gills.

Two dimensional laser Doppler anemometers (2D-LAD) and a high speed video analyzed the drafting process on a Schlumberger GC 14 chain gilling machine. The 2D-LAD determined the speed relationships in the drafting zone during polyester fiber and wool fiber drafting. The delivery rate, ratch, type of pins, pinning density, roll weighting, d..

The Rieter Spinning Systems Technical Documentation.

Rieter Blowroom Systems' VarioSet system uses cleaning intensity and waste amount data to establish optimal operating parameters for a given yarn quality. The fully electronic ABC-Control system with programmable logic control creates a graphic display of all machine conditions, the production and quality data of the cards, and the parame..

Acrylic, PSF Blending.

The Indian textile industry is using more polyester/acrylic blend yarns. Although these yarns yield lighter weight fabrics than do conventional polyester yarns, acrylic yarns offer lower stiffness and better hand. Increasing the percentage of polyester to more than 65 percent results in severe pilling. The main advantage of the blended ya..

Unwinding and Feeding Spandex Yarns.

A range of methods exists to prevent slippage during the processing of such elastic yarns as spandex using optimized friction and tension control systems. The elastomer polyurethane serves as the base for most of these yarns, and its extensibility is up 100 times greater than that of other fibers. During yarn manufacture, the level of dra..

OPTICAL RECEIVER OF MEASURED QUANTITIES FOR THE DETERMINATION OF SLIVER IRREGULARITIES

The fundamentals for developing an optical receiver of measured quantities that determines sliver irregularity are provided, and the validity of the theory is discussed. The hyperlogical solution of the radiation transport equation for transmission is used for deriving an equation of sliver fineness. A special method that enable compensat..
