protective suits for chemical spill response

in their role of responding to potential or actual hazardous chemical discharges, u. s. coast guard response personnel and marine inspectors need adequate protection equipment and procedures to ensure their safety. the hazards associated with chemicals require a wide range of personnel protection gear from gloves and overalls to totally-e..

evaluation of a radiofrequency protective suit and electrically conductive fabrics

a protective suit consisting of an overall with an integral hood, gloves, and oversocks, constructed of an electrically conductive fabric, has been examined theoretically and experimentally for electromagnetic shielding effectiveness (se) at radio frequencies (rf) in the range from 200 khz to 4 ghz. the suit, although originally developed..

high-tech textiles: contribution made by finishing, in an example of functional sports and leisure wear

besides the specific fibre usage and the textile construction, greater importance is currently being placed on the finishing process in the production of functionally destined textiles. various methods have been suggested for the functional sports and leisurewear textiles in order, on the one hand, to achieve waterproof properties, while ..

avoiding the ten most common mistakes in garment drying

if we were to identify the ten most common mistakes in drying, plus ideas for solutions, the first would be allowing goods to dry too long. besides wasting energy and production time, overdrying creates excess friction which wears out fibers and can create pilling. it is necessary to fine-tune dry cycle times and then stick to them. preci..

new detergent mechanism with use of novel alkaline cellulase

microscopic studies of naturally soiled cotton undershirts showed that there was sebum in the microscopic spaces in the interior of the cotton fibers. ordinary detergents did not remove this soil satisfactorily, although they readily removed sebum on the exterior of the fibers. alkaline cellulase, which was compatible with the alkaline in..

vacuum packaging of home furnishings. case study on blankets

the vacuum packaging of blankets has been studied to reduce the bulk of a blanket. the applicability to practical use is also discussed. among results obtained are the following: to reduce the bulk of blankets by vacuum packaging, it is necessary to regulate pre-conditioning by heat drying (without an increase in the level of segmental mo..

product engineering of safety apparel fabrics: insulation characteristics of fire-retardant cottons

the heat-insulation characteristics of eighteen fire-retardant-treated fabrics, two nomex fabrics, and a kynol fabric are examined. exposure both to flame and to radiation sources is employed. for a low level of radiation exposure, fabric thickness correlates well with protection time. as incident heat flux is increased, other less obviou..

study of the friction characteristics of some porous bearing cage materials

a series of friction and wear experiments have been carried out on materials and lubricants used in miniature inertial-grade ball bearings. the materials studied, all used in porous bearing cages, include three types of porous polyimide and three types of cotton-reinforced phenolic. the lubricants used were super-refined mineral oils havi..

hong kong mass transit railway design for performance

the paper describes the history of the system and gives the basic parameters and the philosophies on which the engineering concepts were based. it covers the mechanical and electrical equipment, including choice of train dimensions and composition, method of power supply, train control system, environmental control and revenue collection
