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

a detailed study of the quality and quantity of fine dust and trash removed from cotton fibers by the srrc tuft-to-yarn system in its various stages of processing is presented. collection of fine dust and trash was accomplished by isokinetic sampling from the respective pneumatic systems of the mini-condensers and oe spinners an impaction..

review of processing technology for the utilization of agro-waste fibres

the processing of agricultural wastes such as banana plant fiber and pineapple leaf fiber which might partially substitute for jute or mesta and cotton, respectively, in certain areas is discussed. 26 refs

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..

benefit-cost analysis of the cotton dust regulation

this study applied economic analysis to an evaluation of the occupational safety and health administration's standard. the costs and benefits attributable to the standard were identified, measured, and compared. a period of twenty years was used to estimate the costs of the standard to allow for the cumulative effect of cotton dust contro..
