ways of improving raw material utilization in cotton prespinning

the raw material costs situation is compelling cotton spinners to look for ways to make better use of their feedstock. various approaches are pointed out and discussed in this article, including optimized machine settings, use of machines with higher cleaning efficiency and recycling machine wastes. an examination of the economics reveals..

inter-stage stock control in a series production system with different numbers of parallel machines at each stage

this paper examines the technological and operational factors that affect production planning and control in cotton spinning mills and presents a simulation model developed to assist in maintaining the balance of the production system by controlling inter-stage stocks. the production system is characterized by a series of stages with diff..

cotton dust control studies - effects of engineering controls, washing cotton, and additives

this paper reviews some of the cotton dust control technology studies carried out a north carolina state university since 1973 the purpose of the investigations has been to examine means for reducing respirable dust emission during carding, as well as to evaluate the relative merits of various dust-sampling devices typically the results i..

gaston country buy greenwood

a high-speed electrostatic spinning system for cotton yarns has been developed. the process uses electrical fields to guide individual fibers into the tail of the newly formed yarn, which is twisted as it is being formed. special features stabilize the tail and control stray fibers problems that caused electrostatic spinning to be dischar..

new electrostatic spinning concept for cotton

a new compact design was developed for the electrostatic spinning of cotton yarns by use of the best technology derived from previous research conducted at the southern regional research center, new orleans (usda) and battelle columbus laboratories. the new design consists of a miniature card-type fiber feed system, a rotating grounded ta..

air engineering systems for automatic removal and reprocessing of cotton waste

for the cotton processing mill, air engineering systems are currently available which make it possible to integrate waste collection, waste reprocessing, exploitation of secondary waste and dust in such a way, that, in the final analysis, it is necessary only to dispose of the ash resulting from incineration. an outline of such a system i..

stretch mercerization of cotton fibers. part ii: fabric properties

slack mercerization followed by gradual restretching to the ratio of 1. 25 by a series of closely set rollers in part i of this study was proven to be effective in stretching the individual fibers shrunken during mercerization. the effect of stretch mercerization in roving form using this technique on the mechanical properties of fibers, ..

comparison of diesel engine performance and emissions from neat and transesterified vegetable oils

a single-cylinder diesel engine was operated on a certified diesel fuel, cottonseed oil, sunflowerseed oil, methyl ester of cottonseed oil, and methyl ester of sunflowerseed oil. results comparing the various vegetable oil fuels with diesel fuel generally show slight improvements in thermal efficiency and higher exhaust gas temperatures w..

quality and economy in cotton yarn production

yarn quality is determined not only on the spinning machine, but by every stage in the manufacturing process, from bale to yarn the economics of the operation, too, obviously depend on total preparation and spinning costs. this article deals with quality and economic considerations as part of a detailed description of the total spinning p..

stretch mercerization of cotton fibers. part i. fiber and yarn properties

three techniques were developed by which cotton fibers in roving from were mercerized and stretched to their original length and then neutralized in the stretched configuration. the effectiveness of the three stretching systems was evaluated by testing the processed fibers and yarns. the mechanical properties of the yarns made from stretc..
