prediction of cotton quality as a function of lint cleaner operating parameters

literature was examined and the data was utilized to develop prediction equations for cotton fiber quality as a function of input lint moisture, foreign matter content, fiber length and strength, batt weight, saw cylinder diameter and speed, feed rate, saw loading and combing ratio. fiber properties investigated include length, strength, ..

cotton dust control additives - effects on dust measurements and particle size characteristics

an additive applied to cotton in the textile opening line lowered the levels of card generated airborne dusts and associated microorganisms. dust from cotton containing additive had fewer smaller particles than dust from untreated cotton. the additive altered the nominal 1:1 relationship between airborne dust levels measured by vertical e..

performance of oil milling technologies in india

the existing oil milling plants were visited to collect information on plant performance. in addition to direct measurements, plant records were consulted and discussions held with the managerial and technical staff to obtain the required information on oil recovery and energy requirements. the average recovery of oil in mechanical extrac..

influence of the spinning process, yarn linear density, and fibre properties on the hairiness of ring-spun and rotor-spun cotton yarns

cotton-spun yarns from 34 staple stocks were manufactured by means of the ring-spinning process (34 yarns) and a rotor-spinning process (29 yarns) and tested for hairiness with the shirley hairiness meter. for each spinning system, yarns were spun at two values of yarn linear density (15 and 30 tex for ring-spinning and 30 and 50 tex for ..

effect of processing parameters on the properties of double-rove spun yarn produced on a short staple spinning system

this paper is concerned with the optimization of a double-rove spinning process in the short staple spinning system, using box and hunter's technique of a central compound rotatable design. the influences of strand spacing, twist, and spindle speed on yarn tensile and regularity properties are discussed.

maintaining cotton quality

nine bales of midsouth cotton were subjected to three harvesting treatments, three levels of lint cleaning, three levels of mill opening line cleaning, and two levels of mill carding. fiber properties after ginning were best for the normal-harvested cotton without lint cleaning, but producer returns were best for normal-harvested cotton c..

computer model for simulating the semi-worsted processing of wool

a model for the computer simulation of the processing of scoured wool through to singles yarn via the semi-worsted system is described on the basis of published empirical and theoretical literature. the model accounts for changes in the properties of scoured wood and processing variables over a range of values common in the commercial sem..

cotton-wrapped yarns $em dash$ a process to eliminate sizing and desizing

wrapping cotton yarn with a filament yarn may preclude the necessity for sizing prior to weaving and eliminate desizing and associated size-recovery systems. a study was made to define the properties of cotton/nylon and cotton/polyester spin-wrapped yarn of various filament sizes, weaving efficiencies, and fabric applications. core-wrappi..

characterization of fiber length in slivers

an index is proposed for characterizing the length of fibers in slivers based on the lindsley technique. this index is simple, time-saving, and inexpensive to run and it possesses high sensitivity. results obtained with cotton slivers are described and compared with other methods. 7 refs

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..
