Cotton trash

Cotton Trash and Dust Contents and Airborne Dust Concentration... 

In studies on hamsters and guinea pigs exposed to aerosols of crude and refined extracts from cotton mill trash and CMD, Kilburn et al (59) has further demonstrated recruitment of PMN beneath the basement membrane and on luminal surfaces of intrapulmonary airways and tracheas. When administered as aerosols or dust, polyphenolic extracts from cotton trash and pure and oxidization-polymerization products of quercetin also recruit PMN from the trachea to terminal bronchioles in hamsters (60). 

Gram-Positive or Total Bacteria. Bacillus species are the commonest bacteria in lint, raw cottons, cotton trash, and cotton dust, and may contribute to airborne levels of proteolytic enzymes, but the counts (while high) did not correlate with dust levels, and culture filtrates do not cause histamine release. 

Most all of the organic compounds which have been reported from studies of cotton plant parts and cotton trash have been included in this review. Only those which seem most unlikely to be cotton-derived natural products have been excluded. For example, the phthallates reported as "air space volatiles of the cotton plant" are likely artifacts derived from cjommon plastics (.9) some hydrocarbons found to be in cotton lint and waste probably came from a source obtained from petrolexim W and aflatoxln is presumably a mold metabolite (36). A few other compounds have been excluded for similar reasons. 

Brown and Berni (26) developed a novel method to separate fine dusts (in the respirable range) from cotton trash material. The dust is separated on sieves by mechanical agitation. The trash typically consists of condenser filter cake material collected by an air filtration system attached to a processing unit such as a...

Morey, Sasser, Bethea, and Kopetzky ( ) examined and classified the plant parts in Shirley analyzer waste from six raw cottons that had been processed through the model card room at North Carolina State University. Bract, leaf, weeds, veins and endocarp were the major plant parts present. Bract and leaf constituted up to 52 percent of the foreign matter in the cottons they examined. There was evidence that using gin lint cleaners reduced the total trash content but Increased the proportion of bract relative to other foreign-matter particles remaining in the fiber. 

Cylinder cleaners are an Important type of seed-cotton cleaner. They remove small trash (16, 28) and operate by scrubbing seed-cotton against a grid-bar grate (inclined cleaner) or by the interaction of an upper and lower set of cylinders (Impact cleaner). Cylinder cleaners are well described in the Cotton Glnners Handbook (29).
