Modern Developments in Spinning

Automatic bale blending machines process up to 1,500 kilograms of cotton fiber per hour. Oblique angled opening improves the distribution of cotton tuft density as the various bales are blended, which improves control over count variations in the card sliver. Saw tooth opening machines more effectively clean the speed coats from saw ginne..

ITMA'99: LMW's Revolutionary Spinning Machinery for the Millennium

Lakshmi Machine Works Limited, a leading Indian spinning machinery manufacturer, will be a first time exhibitor at ITMA 1999 in Paris. The company will display its Flexifloc automatic bale plucking machine for blowroom lines; LC300A high speed carding machine with improved suction, simple drive system, large can size, reduced noise emissi..

Cop Tracking System Upgrades Quality.

The function of a cop tracking system is to use information from the yarn clearer on the winding machine to analyze the performance of individual spindles on a ring spinning machine. The system aids in the detection of defective spindles in a timely fashion and the evaluation of yarn quality and quantity from each spindle. In particular, ..

방적공장에서의 원료소요량과 생산량 산출

The Obligativity of Introduction Autoleveller Devices in the Long Hemp and Flax Fibers Spinning Mill.

A major problem for spinning mills that process long hemp and flax fibers is to be able to manufacture fine yarns, which are in high market demand, without a concomitant increase in the fiber breakage rate. A relatively high level of fiber uniformity is important in the production of fine yarns. The wool industry has used autolevelers to ..

Manufacture and Applications of Elastane Combinaton Yarns.

An overview of elastane combination yarns discusses physical properties, production methods, yarn types, covering methods, ring twisting, doubling, stretching, twisting on DD twisting machines, the Hamel hollow spindle method for elastic twist, preparation of covering yarns, twisting via Elastotwisting machines, core spun yarns, the SiroS..

Some Properties of All-Cotton-Waste Yarns.

Cotton waste generated during preyarn processing can by collected and recycled as part of a new yarn blend. Studies determined that having up to 5 percent of recycled fibers in a yarn blend has no negative influence on yarn values. A study examined various compositions of yarns made using first cut cotton waste gathered from different mac..

LMW's New Generation Machines.

Lakshmi Machine Works Limited, the world's largest supplier of ring spinning machines, will inroduce the new Flexifloc automatic bale plucking machine, LC 300A carding machine, LFS1660 speed frame, and XLA30 ring spinning machine at ITMA 1999. The Flexifloc enhances performance and automation of opening with a production capacity of 2,000..

The Use of Neural Nets to Simulate the Spinning Process.

Researchers used the X(2) test to study the goodness of fit of graphs for the learning values and test values for the relative error published in a paper on the use of neural networks to simulate the spinning process by Pynckels and his coworkers. Results showed that the distribution of relative errors was a Poisson distribution. Other di..

Jute -- The Golden Fibre -- Rediscovered.

The National Jute Development Program in India developed a variety of new processing technologies and new jute products. The program improved methods of blending jute with cotton, viscose, acrylic, polyester, polypropylene, and other fibers. The Indian Jute Industrial Research Association developed a fungal enzyme softening treatment that..
