effect of modular storage of arizona seed cotton on levels of aflatoxins in seed

samples were drawn from 40 free-standing modules of commercially grown arizona seed cotton and analyzed for aflatoxin at the time of moduling and after 27 days of field storage. thirty modules derived from spindle harvested cotton showed no significant increase in aflatoxins following modular storage, while all 10 modules packed with seed..

radiation-induced grafting of acrylic acid onto polyester fiber

radiation-induced grafting of acrylic acid (aa) onto drawn polyester fiber was carried out with the mutual irradiation method to impart hydrophilic properties. it was found that grafting occurred smoothly without homopolymerization outside the fiber when a small amount of ferrous, cuprous, or curpic salt was added to the monomer solution...

removal of phenthiuram from wastewater

to eliminate phenthiuram, a broad-spectrum disinfectant used to treat cotton seeds, in the wastewater of seed plants a reagent method is recommended involving the addition of bleaching powder and calcium oxide in combination with treatment with type kad-iodine activated charcoal. the optimum treatment conditions are: ph 11-12, specific co..

cotton's role in the new technologies

the author discusses cotton fiber properties important to new spinning technologies, such as rotor, air-jet and friction spinning it is shown that these fiber properties affect both the spinning performance and the end-product quite differently from the conventional ring spinning method. the article shows the number of rotor spinning posi..

effect of donor-acceptor substances on the heterogeneity of cellulose acetate spinning solutions

microgel particles (mgp) of secondary cellulose acetate (ca) spinning solutions can affect the properties of the solution and of the fiber spun from it, by forming heterogeneous inclusions in the solution. controlled regulation of the microgel structure of spinning solutions can be used to optimize the properties of acetate fiber and inte..

quick, room temperature method for polyester-cellulosic blend analysis

the composition of polyester-cellulosic blends is usually chemically analyzed using the standard sulfuric acid methods involving the dissolution of the cellulosic component. these methods are not only time consuming but also need care in adapting the proper procedure because the reagent concentrations and the treatment conditions (time, t..

danger: dust

dust arising during the processing of cotton, flax or hemp has been recognized as a health hazard for over 250 years; the term 'byssinosis' was used by a. proust as long ago as 1877. cotton dust has an insidious effect, and the appearance of symptoms of byssinosis often takes about 10 years. the clinical symptoms are very similar to those..

conformational anisotropy of liquid crystalline side chain polymers: a small angle neutron scattering study

the anistropy of the conformation of two kinds of comblike liquid crystal polymers, a polymethacrylate and a polymethyl siloxane has been measured in the nematic and smectic phases by small angle neutron scattering (sans). the global sizes (parallel and perpendicular to the director) of one labelled chain and their temperature dependence ..

thermal decomposition of humic acids of high-moor and low-moor peats

the thermal decomposition of the humic acids of reed and cottongrass-sphagnum peats has been studied. the humic acids of high-moor peat are characterized by a lower thermal stability, which is shown in the formation of a larger amount of volatile products on dry distillation and a shift in the intervals of their evolution to the region of..
