washed cotton $em dash$ manufacture, properties, and processing $em dash$ 1. experimental program

in the reported experiments, investigations dealing with the washing of cotton of sample sizes ranging from 1 to 10,000 pounds ( 45 to 4,536 kg) have been carried out. processes have included both batch-washing of loose fiber and continuous washing of fiber in lap form. results of the washing experiments have shown that approximately the ..

simplified asme acceptance test procedure for steam turbines

a simplified procedure is proposed, which reduces the cost of steam turbine acceptance testing without significantly affecting testing accuracy. this simplified acceptance test procedure is applicable to both fossil and nuclear power plants. it involves only the measurements required to calculate heat rate and to compare the test value to..

carbohydrazide found to be an effective scavenger for reducing free formaldehyde

twelve compounds reported to have the ability to combine with formaldehyde and to retard or inhibit its release from resin-treated fabric were evaluated. one of these, carbohydrazide, demonstrated superior performance in lowering formaldehyde while minimizing effects on durable press performance. full-scale plant trails on both cotton and..

toxicity of off-gases from furnishing materials: a review

relative toxicity data are presented for the off-gases from various materials used in furnishings. 9 refs

closed-boll cotton $em dash$ 3. effect of treatment with propylene oxide on sorptive and mechanical properties of fibers and yarns

cotton bolls were harvested at three stages before boll opening (closed bolls), and after opening on the plant (field-opened bolls) half of the closed bolls were maintained in the never-dried state; the remaining closed bolls were allowed to air-dry and open off the plant. never-dried closed-boll fibers, rewet dried closed-boll fibers, an..

optimize oxygen control in your boiler-feed system

corrosion protection during operation and shutdown constitutes a major objective of any feedwater-conditioning program. physical and chemical methods combine to minimize the effect of dissolved oxygen on preboiler components, but deaerators must be operated efficiently and scavengers should match system conditions closely

protection from flame and heat

protection from fire and heat, of varying kinds and degrees, usually is met by the use of ordinary work clothing that has been made flame-resistant. that is, it is slow burning and self-extinguishing, once the flame, or source of combustion, has been removed. the article discusses several types of flame-resistant materials, including ammo..

solar gasification of coal, activated carbon, coke and coal and biomass mixture

subbituminous coal, activated carbon, coke and a mixture of coal and biomass were gasified using direct solar irradiation in a 23-kw solar furnace located at the u. s. army white sands missile range, white sands, new mexico. the sunlight was focused directly on the coal (or alternate fuel) bed being gasified through a window in the reacto..

investigation of a practical method for reducing free formaldehyde on n-methylol sensitized fabrics using a formaldehyde scavenger

in view of the uncertainties associated with the continued use of formaldehyde based resins by the american textile industry, practical methods of minimizing formaldehyde release from textile materials are of extreme importance. one such method of reducing formaldehyde release could be the incorporation of a chemical in the resin bath to ..
