advances in radio frequency garment drying

radio frequency and vacuum technologies have been used separately in the textile industry for many years. however, only in the last few years have they been used simultaneously during the drying cycle. the result is the cool dry principle which means that during the entire drying cycle, the fiber, whether natural or man-made, in loose sto..

improving carpet wastewater treatment

electrochemically generated ferrous hydroxide removes a broad spectrum of components in textile processing wastewater, including bod, cod, color, suspended solids, and heavy metals. depending upon the type of effluent the efficiency in pollutant removal is often greater than 90

what is different in leather dyeing today

customer requirements in shoe upper, garment and upholstery leather and leather goods have changed. different quality leathers and some new fastness properties are in demand and have to be met by leather dyeing. dye selection and dyeing methods are discussed to meet these requirements.

using milling to control the hygral expansion of piece-dyed worsted fabrics

it is shown that a light milling after dyeing will reduce the hygral expansion of piece-dyed fabric. this simple procedure provides the finisher with a corrective approach to controlling the hygral expansion of piece-dyed fabric. only a light milling is required on pure-wool fabrics, and the subjective changes in handle and surface appear..

recovery of direct dye and acid dye by adsorption on chitosan fiber - equilibria

the recovery of direct dye and acid dye from dilute aqueous solution by adsorption on chitosan fiber, which is cheaper than an activated carbon fiber, appeared technically and economically feasible. the amounts of adsorption of brilliant yellow (direct dye) and acid orange ii (acid dye) on the chitosan fiber were much larger than that for..

improving dye waste water treatment

a discussion is presented of the standards now being enforced which include: biochemical oxygen-bod demand, chemical oxygen demand-cod, total suspended solids-tss, total dissolved solids-tds, fats oils and greases-fog, and to a lesser extent color. the most toxic contaminant found in textile dyeing waste water are heavy metals which are t..

experience with two-stage activated sludge plants for industrial wastewaters in korea

the two-stage activated sludge process (ab-process, i.e adsorption activated sludge process) invented by boehnke was successfully applied to several municipal and industrial wastewaters in korea. the first large wastewater treatment plant for the combined effluents of 22 textile dyeing companies was constructed in taegu and started operat..

cultivation of phanerochaete chrysosporium and production of lignin peroxidase in novel biofilm reactor systems: hollow fiber reactor and silicone membrane reactor

the white rot fungus phanerochaete chrysosporium and its extracellular enzyme lignin peroxidase are both known to catalyze the transformation and, in many cases, the degradation of several hazardous compounds and are, therefore, promising candidates for application in hazardous waste treatment. the application of p chrysosporium in large-..

effects of sputtering and plasma etching on the surface reactivity of graphite

the surfaces of highly oriented pyrolytic graphite (hopg) samples were treated using two different methods, exposure to an energetic oxygen ion beam and immersion in an oxygen ion plasma, and the reactions which occur during treatment were characterized using high-resolution electron energy loss spectroscopy (hreels), temperature programm..

effect of surface treatment and moisture on carbon fibers strength in microplastics

the reason of imperfect realization of carbon fiber durability strength were analyzed. moistening with fillup of defects of transition and macroscopic size decreases the coefficient of adoption of the carbon fiber durability. chemical or thermal treatment of the carbon fiber does not assure high coefficient of realization of durability, i..
