energy conservation in textile mills - need and scope

with 706 mills having 21 million spindles and 208,000 looms the mill sector of the cotton textile industry occupies an important position in indian economy. it is a major energy consuming sector with an annual consumption of nearly 600 million liters of furnace oil, 200 million liters of hs diesel oil, 18 million liters of lubricants, 20 ..

evaluation of cleaning and washing processes for cotton fiber $em dash$ 7. microbiological evaluation

results of an experimental study are presented which demonstrate that precleaning, washing, steaming plus washing, and steaming plus hot alkaline scour result in statistically significant decreases in the gram-negative organism counts and the endotoxin content of the cotton and of the airborne dusts in the model cardroom when the cotton i..

evaluation of cleaning and washing processes for cotten fiber $em dash$ 6. histamine analysis of cotton material

results of chemical and biological assay of dust material obtained from carding washed and unwashed cotton is presented which suggests the occurrence of a modest decrease in the histamine content of the dust following the washing process. histamine-releasing activity is significantly reduced in the washed samples when analyzed by chemical..

evaluation of cleaning and washing processes for cotton fiber $em dash$ 5. characterization of dust samples

in the reported experiments, fine dusts in trash samples collected on pneumafil filter during carding of washed cottons were separated into 20 to 38- $mu$ m and $less than$ 20- $mu$ m fractions, their ash contents determined, and elemental analyses performed on the resulting inorganic residues. the quantity of fine dusts separated was aff..

evaluation of cleaning and washing processes for cotton fiber $em dash$ 4. spinning and yarn properties

in the reported experiments, mechanically-cleaned and/or washed cotton card sliver was processed into both ring- and open-end-spun yarn. three yarn counts, two open-end and one ring, were spun ends-down were found to be low for a coarse count open-end yarn and high for a medium count. the ring-spun yarn exhibited mixed ends-down results. ..

evaluation of cleaning and washing processes for cotton fiber $em dash$ 3. carding and dust levels

results of an experimental study are presented which show that washing decreases the dust concentrations emitted from cotton processed in a model card room. the higher the washing and rinsing temperatures, the greater the reduction. in 5 of 10 trials, the amount of dust added to the background concentration in the card room while processi..

evaluation of cleaning and washing processes for cotton fiber $em dash$ 2. washing processes and equipment

a brief survey of wet-processing equipment of potential interest for washing cotton staple prior to spinning is provided. a series of seven different washing treatments ranging from simple warm- and hot-water washes to a full scour and bleach were applied to cotton in continuous batt formation for subsequent evaluation by other authors of..

dust-trash removal by the srrc tuft-to-yarn processing system

an impaction-type precutter permitted classifying dust particles from the sampled air into two fractions, one greater than 15 $mu$ m aerodynamic diameter and the other less. three grades of cotton, sm, slm, and sgo, were used and a comparison was made between the proportion of fine dust removed by the system and the residues found in conv..

engineering methods for the control of mill dust

osha (occupational safety and health administration) has done a lot of work establishing a new standard of exposure to cotton dust and in giving reasons for it. the movivation is mainly drawn from a medical standpoint. the new standards have initiated much discussion, mainly about their financial impact and their feasibility. also, there ..

production and quality control in cotton spinning

this article is intended to stimulate ideas on the part of those responsible for quality control. accordingly it is not proposed to give the latest catalog of the usual testing instruments and quality control procedures nor is judgement passed on commercial testing equipment. instead the interactions between the cause and effect are exami..
