Stickiness of cotton fiber is usually caused by honeydew deposits from phloem- feeding insects, including whiteflies and aphids. This work was conducted to determine if the specific sugars commonly found in insect honeydews have different stickiness

The OSHA cotton dust standard issued in 1985 exempted cottons washed on either a rayon rinse system or a continuous batt system except for medical surveillance every two years. Human challenge studies with these cottons demonstrated that the acute pu

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 additiv

Trimethylsilyl derivatives of the water-surfactant-soluble components of cotton fibers were analyzed by gas chromatog raphy. Substantial quantities of sucrose and turanose were found on localized areas of some very sticky cottons from the San Joaquin

The gas-liquid chromatographic analysis of the water-surfactant soluble components and or natural contaminants on cotton fibers was refined and made quantitative by use of an internal standard. The effects of fiber maturity and growing and harvesting

Late season rains on the 1984 crop in the Mississippi Delta cotton-growing areas prompted increased research of this weathered cotton. Cotton Incorporated and USDA quickly noted the detrimental effects on quality caused by the heavy rains after boll

Oil contamination of cotton is a recurring problem that adversely affects cotton quality. Processing problems occur in carding through spinning, and both yarn strength and appearance are lowered. Problem severity increases as the level of contaminati

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

The extreme stickiness of some 1977 Acala SJ California cottons was caused by localized areas of high sugar contamination tentatively identified as honeydew se cretions from whiteflies. Processing of these cottons under normal conditions was virtuall
