prediction of cotton yarn properties using artificial intelligence

the possibility of determining cotton yarn properties using artificial intelligence techniques is studied. the advantages of this approach are presented. on the basis of experimental results the usage of machine learning and expert systems in the domain of spinning textile technology is estimated and suggestions for further research work ..

production and evaluation of cotton/viscose yarns with long staple viscose fibers on the surface and in the body

two cotton/viscose yarns, one in which a thin strand of long staple viscose fibers spirally wrapped the yarn surface and the other in which the viscose fibers remained scattered in the body of the yarn, were produced and their properties compared with a 100 cotton yarn. an attempt was made to determine viscose fiber compositions that give..

study of double-rove yarn hairiness in the short-staple-spinning sector

a factorial-analysis technique is applied to study the effects of strand spacing, twist, and spindle speed on the hairiness of double-rove yarn. a wide range of twist levels and spindle speeds is covered by spinning yarns from two different types of fibres, namely, cotton and a polyester-fibre/cotton blend, in order to study the interacti..

visual system for automatically inspecting yarn packages

cotton spinning has today reached a high technological standard not only in production, but also in product handling, e.g. in doffing, transportation, identification, weighing and packing progress is thus being made towards the 'no-man factory'. the missing link in the automation chain has up to now been the visual inspection of yarn pack..

failure mechanism of urethane elastomer coated fabric collapsible fuel tanks. technical rept

this report investigates the failure mechanism of urethane elastomer coated fabric collapsible fuel storage tanks. past work has dealt with fuel degradation causing the tanks to fail but that work has met with failure. the mechanism that causes these tanks to fail is an extraction process whereby the protective ingredients in the polymer ..

a search for an appropriate technology for decentralised cotton spinning industry in rural india

the paper describes the development of a small scale spinning unit in india. this development grew out of attempts to improve the khadi hand spinning technology when it was realized that it was at an economic standstill. a 432 spinning unit has been developed which can produce 20s count yarn of a quality acceptable to the cottage weavers,..

process for preparing lubricating oil from used waste lubricating oil

a re-refining process is described by which high-quality finished lubricating oils are prepared from used waste lubricating and crankcase oils. the used oils are stripped of water and low-boiling contaminants by vacuum distillation and then dissolved in a solvent of 1-butanol, 2-propanol and methylethyl ketone, which precipitates a sludge..
