spin finishes for cotton

cotton has an exceptional natural finish, but under adverse conditions of weathering, this finish may deteriorate to the extent that processing quality is altered. changing technologies involving higher processing speeds and new spinning systems have placed increased demands on the fiber properties of all cottons. spin finishes could reas..

update on new spinning technologies and their impact on cotton production and marketing

the authors explain the reasons behind the growing need for finer, stronger and cleaner cotton qualities. they put in perspective the various spinning technologies employed in united states textile mills in 1988. they also address some of the critical opinions that changes are not necessary. a proposed valuation system of cotton propertie..

cotton dust and its impact on the respiratory system of those working at a cotton spinning mill in vietnam

in workers at a cotton spinning mill in vietnam who were exposed to the action of cotton dust first-stage byssinosis was detected in 34. 1 of those examined, while second-stage byssinosis was detected in 8. initial manifestations of byssinosis (coughing, a sensation of pressure behind the sternum, a vaguely expressed 'monday morning syndr..

machine linking-up in the spinning area

integrated systems in the cotton spinning area have attracted a great deal of attention. the integration of the various processes from bale breaking right up to and including the card has already been accepted by many companies as the state of the art. in the present bullentin, attention is focussed on the link-up of ring-spinning machine..

properties of fabrics woven from twistless cotton yarns produced by wrap spinning

we have determined the effects of structure on the strength properties of fabrics woven from twistless cotton yarns. the twistless yarns were prepared on a wrap spinning machine, which produces twistless staple fiber yarns held together by a fine multifilament wrap. the experimental yarns were spun with a water soluble polyvinyl alcohol w..

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 ..

comparative spinnability of ring-and rotor-spun cotton yarns

the relationship existing between the fibre properties and yarn parameters of a set of 72 cotton-spun yarns (36 ring-spun yarns and 36 rotor-spun yarns) has been reported. in a second set of experiments, lots of cotton from 34 varieties were investigated, and 68 cotton ring-spun yarns involving two linear-density levels (15 tex and 30 tex..

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.

kanebo links machines in modern u.s. operation

using what it calls kanebo continuous spinning system (kcs), a new japanese plant in tifton, ga., is producing 50-50 combed cotton-polyester (du pont) yarn by linking seven processes into four the plant's operations consist of: opening and blending followed by chutes feeding cards; lap winding automatically feeding ribbon winding which au..

effect of lubrication on spinning properties of dyed cotton fibers

in order to improve cotton spinnability after wet processing, it is necessary to treat the fibers with lubricants. this study reports the influence of four commercial lubricant formulations on cotton sliver cohesion as measured by sliver tenacity. sliver cohesion passes through two maxima as a function of lubricant concentration in the ra..
