TRENDS IN POWER CONSUMPTION DURING THE SPINNING OF COTTON AND MANMADE FIBERS.

NITRA researchers conducted a detailed examination of trends in power consumption during the spinning of cotton and manmade fibers at their Ring Frame Pilot Plant in Ghaziabad. The examination focused on process parameters, such as spindle speed, spindle lift, ring diameter, and traveler weight. The data were used to develop a mathematica..

EFFECTS OF NONLINT REMOVAL ON SPINNING PERFORMANCE AND THE QUALITY OF COTTON YARNS. PART 3.

The effects of ginning cotton without lint cleaners or with one or two lint cleaners on ring spinning performance and yarn properties were examined. Sample sliver was either single or tandem carded. Ring spinning produced both carded and combed yarns. The strength of the combed yarn was generally greater than that of the carded yarn. Both..

EFFECTS OF NONLINT REMOVAL ON SPINNING PERFORMANCE AND THE QUALITY OF COTTON YARNS. PART 3.

The effects of ginning cotton without lint cleaners or with one or tow lint cleaners on ring spinning performance and yarn properties were examined. Sample sliver was either single or tandem carded. Ring spinning produced both carded and combed yarns. The strength of the combed yarn was generally greater than that of the carded yarn. Both..

SPINNING MACHINERY MARKET IN RECESSION.

The Internatonal Textile Manufacturers Federation has released a report covering the sale of short and long staple ring spindles, and open end rotors in 1992. Statistics for 1992 shipments, 1991 installed spinning capacities, and cumulative shipments form 1983-1992 of ring and open end spinning mahcines to Agrica, North America, South Ame..

AUTOMATIC TRANSPROT SYSTEMS FOR COPS, SPINNING CANS, AND YARN PACKAGES - COST/UTILIZATION.

The current treand toward automation of the spinning mill will continue, with increased emphasis on automated systems for transporting cops, spinning cans, and yarn packages between processes. An economic analysis of manual and automated transprot systems indicates that the installation of automated transprot systems is economically viabl..

Traveling Cleaners.

Traveling cleaners are widely used in both spinning and weaving operations. Their use does not totally eliminate manual cleaning, but investment in this equipment has provide very cost effective. Increases in the production speed of looms increases the volume of lint and fly that is generated. This waste is likely to cause such problems a..

Tool For Better Yarn.

Cone Mills has installed Zellweger Uster's Polyguard yarn clearing and monitoring system at its open end spinning mills in Forest City and Henrietta, North Carolina. The information provided by these systems has allowed Cone Mills to improve yarn and fabric quality. The Polyguard system provides spectrograms and information about imperfec..

Rieter Introduces Complete Automation From Drawing To Spinning.

In October 1993, Rieter introduced a new system for yarn package handling and transprot. The CUBIcan system consists of an RSB851 drawing frame, an automatic guided vehicle, and an R1 rotor spinning machine. This system allows completely automated production from drawing to spinning. CUBIcan's unique, rectangular yarn packages also offer ..

Role of False Twist in Wrap Spinning.

A high level of false twist in wrap spinning significantly affected yarn appearance and mechanical properties. Yarn spun under these conditions had a tortuous sturcture, whereas yar spun without a false twist crimping mechanism was smooth. False twist and zero false twist wrap yarns had a comparable twist strength relationship; however, t..

Prospects of Success for Information Technology in the Spinning Industry.

Investments in information technology must be tailored to the strategic objectives of the spinning mill. Any well planned implementation of computer integrated management information systems must initially consider the actual status of information systems must initially consider the actual staus of informatio processing in the facility. A..
