Cotton Testing

Effect of alkali treatment of lower concentrations on the structure and tensile properties of Pakistan’s coarse cotton fibre

“…In order to spin cotton fibres into reasonable quality ring-spun yarn, in general the least number of fibres are required in the yarn cross section is 90 fibres for carded yarns and 70 for combed yarns (Steadman, 1997). For open-end yarns and air-jet spun yarns this requirement is at least 110 fibres (Steadman, 1997) and 75 fibres (Bange et al, 2009) respectively. The number of fibres (n) in the yarn cross section can be estimated from the relation: fibr e ya r n tex tex n  Where texyarn and texfibre are the linear densities of yarn and fibre respectively (Klein, 1998).…”

Endotoxin Eradication Techniques and Their Effect on Lint Chemical Constituents

“…Therefore, continuous inhaling in that toxin contaminated environment, the textile workers become victim of the respiratory disfunctioning, particularly. Research tends towards the conclusion that microdust, mostly In the range of 1 to 5 μm, carried endotoxin that emommuletively impair lung's capacity and lead to Byssinosis (Steadman, 1997). Different techniques were adopted in the pot to reduce the Byssinogenic potential of raw cotton and it ie generally agreed that the causatives are water soluble materials.…”

Single Cotton Fiber Properties of Low, Ideal, and High Micronaire Values

“…The seven length groups from these cottons indicate that longer cotton fibers appear to contain more crimps per cm. The results suggest that the Favimat is satisfactory for measuring current and future cotton properties.Once-over cotton harvesting removes all cotton bolls from the plant [25), with mature cotton bolls found near the base and stem of the plant and natural variations of immature cotton bolls throughout the plant [38]. Cottonseed hairs (fibers) are removed, separated, and cleaned from cotton bolls by ginning to form cotton bales containing fibers from the entire plant.…”
