THANNIN INHIBITS INTRACELLULAR CALCIUM AND cAMP PATHWAYS.

Tannin, isolated from cotton bracts, inhibits chloride and water secretion across the airway epithelium. Since intracellular calcium (Ca) and cAMP levels regulate chloride secretion in airway epithelial cells, the effect of cotton bracts tannin on intracellular Ca in response to epinephrine and bradykinin stimulation, and its relationship..

SAMPLING FOR COTTON DUST

A sound protocol for generating, collecting, weighing, and storing of cotton dust is required to produce reliable results in byssinosis research. The primary objective of this protocol should be the acquisition of accurately weighed and contained quantities of dust that are physically, chemically, and microbiologically as similar as possi..

COMPREHENSIVE CONTROL FOR RING SPINNING PROCESS.

Reiter and Zellweger Uster have collaborated to produce a computerized interface between increasingly complicated spinning machinery and the workers charged with its operation. As the spinning process becomes more automated, fewer individuals supervise a wider variety of more sophisticated machines. Ringdata 4-R makes full reports on the ..

UNCONVENTIONAL SPINNING PROCESSES LEAD TO COMPLETE AUTOMATION.

Air jet and rotor spinning machines at the 1991 ITMA featured increased automation and a widening of the yarn count range. Air jet spinning machines exhibited higher production rates, with delivery speeds of up to 300 meters per minute. Automation in air jet and rotor spinning did not stop at the spinning process, but included auxiliary p..

INTER-MACHINE LINKING AND PROCESS CONTROL IN SPINNING.

Increased productivity in spinning mills can be achieved by reducing labor costs through extensive automation of transport systems between machines. Machinery for process linkage, materials transport, and materials handling was exhibited at the 1991 ITMA. Equipment made by Saurer, Murata, Toyota, Nissan, Pieter, Zellweger Uster, Hollingwo..

PREDICTION OF COTTON YARN PROPERTIES USING ARTIFICIAL INTELLIGENCE.

Artificial intelligence was used to predict cotton yarn quality based on measurements of cotton fiber properties. These properties included strength, mean staple length, color, maturity, and trash content. The accuracy, usefulness, and reliably of the predictions can be increased by adding more properties. Cotton yarn quality can be defin..

PRODUCTION DATA PROCESSING AS A COMPONENT OF INTEGRATION IN AUTOMATED SPINNING MILLS.

Data Processing systems, operating in conjunction with electronic monitoring and control systems, have emerged as a vital component of automated and integrated yarn production. Several trends in data processing for spinning mills are apparent: data processing systems are being used by management for planning and supervisory functions, onl..

TOPICAL TREATMENT OF WEATHERED COTTON FOR BETTER PROCESSING. PART 2. THE FRICTIONIZER EFFECT

Extensive weathering of cotton prior to harvest can cause it to be difficult to process. The treatment of weathered cotton with lubricants to improve processability was evaluated. These lubricants included an ester(butoxythyl stearate)and a commercial, silicon-based softener(Y-12246 Cationic Silicone Emulsion). The effect of adding colloi..

LATEST DEVELOPMENTS IN HIGH-DRAFT AND CLASSIC DRAFTING UNITS FOR SPINNING FINE COUNTS.

High-draft and conventional drafting machinery and equipment for spinning fine count yarn was exhibited at the 1991 ITMA. Suessen, Fehrer, and Lummus Mackie exhibited high-draft drafting units fro ring spinning machines. These units were fitted on Fehrer's DREF ring spinning machine, Suessen's RingCan aliver ring spinning machine, and Lum..

ITMA SURVEY 13 -- LONG STAPLE SPINNING, WOOLEN, AND WORSTED PROCESSING

There were few revolutionary developments in long staple spinning, woolen processing, or worsted processing machines at ITMA 1991. Most machines exhibited refinements and improvements to previous cleaning, feeding, and carding machines; worsted and semiworsted carding machines; and worsted combing machines are described. Gill boxes, drawf..
