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

filtration of cotton dust by lint filter media

the performance of the media used in cotton-mill filters has been examined. efficiencies were found to be only of the order of fifty percent for the test aerosols used, and this mainly reflects the high proportion of fibrous material, or lint, which is stopped at the surface of the filter. the finer dust component of the aerosol is captur..

application of ultrasonic forces to remove dust from cotton

previous studies have led to the determination of the forces of attachment of dust to cotton and of the forces required to remove such dust from cotton. building on the results of the previous research, a theoretical model has been developed for predicting the intensity of a sonic or ultrasonic field that would be required to remove dust ..

irrigation for crops in a sub-humid environment - vii evaluation of irrigation strategies for cotton

empirical functions to predict the nitrogen uptake, increase in lai and minimum leaf water potential (lwp) of cotton were incorporated into a water balance model for the namoi valley, n. s w. a function was then developed to describe the lint yield of irrigated cotton as a function of water stress days at 4 stages of development, total ni..

spatial variability of nitrate in irrigated cotton: i petioles

geostatistics, specifically the use of variograms and kriging, was used to determine the spatial variability of nitrates in cotton (gossypium hirsutum l. ) petioles. petiole nitrates were shown to be spatially dependent in seven commercial fields. this spatial dependence can range from insignificant, where the inherent variability of samp..

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, ..

economic-engineering assessment of a hypothetical tuft-to-yarn textile mill

an economic-engineering simulation model has been developed for a hypothetical textile mill operating an integrated, continuous-flow, tuft-to-yarn (ty) system. the model was used to calculate costs of producing cotton denim yarns with two different ty configuration mills. these were compared with a similar model for a conventional open-en..

look good, are good

this paper reviews the status of textile machinery in italy it is pointed out that, the contrasts in the textile and textile machinery industries of italy, from the myriad small specialist firms to the giant operations, are not reflected in the products themselves, where high quality, enhanced by design flair, is almost universal. activit..

anaerobic digestion of cotton dust from textile mills

cotton dust contains a large organic fraction which can be digested anaerobically to obtain a stable product which can be used as a manure in addition to the biogas produced, which can be used as fuel. laboratory studies on anaerobic digestion of cotton dust were carried out for one year. the volatile solids destruction ranged between 30...

measurement of electric charge on airborne dusts in textile industry workplaces

airborne dusts become electrified during mechanical dispersal, and this may have a significant influence on their subsequent behavior. this paper presents an extensive series of measurements on the states of charge of airborne dusts at a range of jute, flax, cotton, glass, and asbestos textile industry workplaces distributions and magnitu..
