Roler Lapping during Cotton Processing Causes and Remedies.

Roller lapping causes loss of production, higher waste levels, deterioration in yarn quality, and increased costs. Sticky cotton leaves deposits on calender rolls, carding crush rolls, drawing and combing rolls, speed frames, and ring spinning machines. T

Spinning Microdenier Polyester Staple Fibre.

JCT Mills outlines recommendations for spinning microndenier yarns from 0.8 denier filaments. JCT polyester fibers require no tinting or additional oil applications. Polyester and combed cotton should be blended at the mixing stage to ensure better carding performance and minimize roller lapping. An opening line comprising a hopper opener..

Comparative Trials of Ring and Rotor Yarns.

Researchers tested the comparative surface and abrasion resistance of ring spun and rotor spun yarns. They used a Staff tester, to simulate the processing behavior of staple fiber yarns, in combination with a Zweigle hairiness measuring unit to determine surface changes expressed as a change in yarn hairiness. Data showed that rotor spun ..

Comparative Trials of Ring and Rotor Yarns.

Researchers studied force and elongation behavior during tensile loading of ring and rotor spun yarns. Higher tensile yarn strength resulted in greater resistance to deformation during processing. The ring spun yarns offered slightly higher maximum tensile strength and maximum force/elongation values than rotor spun yarns. Research showed..

Optimisation of the Fibre-to-Yarn Process Using Genetic Algorithms.

Researchers simulated and optimized the fiber to yarn production process using a backpropagation neural network combined with a genetic algorithm. The neural network models the process, using the machine settings and fiber quality parameters as input and the yarn tenacity and elongation as output. The genetic algorithm then calculates the..

Expert System for a Cotton Spinning Mill.

Researchers developed an expert system for cotton yarn spinning mills to select raw materials and spinning conditions, control machine settings and systems, advise on problem resolution, and control bale stock. Researchers considered the relevance of 100

Orbit Ring/Traveller System.

The Orbit system for ring spinning, developed by Rieter, Bracker, and Prosino, commands a significant share of the high performance spinning market. The large traveler contact service allows reduced specific surface pressing, optimal heat conduction, good yarn values, and high consistencies between spinning positions. The Orbit performs b..

Improved Raw Material Utilisation in Rotor and Ring Spinning.

Fiber to fabric engineering requires collaboration between fiber producers and textile machinery manufacturers to improve raw material utilization. The spinner, considered the first link in the manufacturing chain, must provide an optimum yarn for the subsequent processes. Because lot sizes are decreasing, spinners must use the same raw m..

Optimisation of Quality and Material Costs in Production of Cotton Yarn.

Raw materials represent the major share of yarn prices in cotton spinning mills. To reduce costs in cotton yarn spinning, mills must reduce the price of fibers as components of a cotton blend. Appropriate computer based information and control systems effectively monitor and control yarn manufacturing stages. Researchers developed a model..

SPIDERweb Monitoring System.

Rieter Textile Systems' SPIDERweb fully integrated monitoring system collects, prepares, and displays all quality and production data from Rieter spinning machines. A Microsoft Windows interface allows simple operation and central machine settings. SPIDERweb offers quality improvements, raw material optimization, production increases, and..
