Removal of dark green PLS dye from textile industrial waste through low cost carbons.

Low cost carbons were prepared from Palm nut shells, Cashew nut shells and Broom sticks by Sulphuric acid process and characterised. The activities of these carbons (PNSC, CNSC and BSC) were compared with that of high cost Commercial activated carbon (CAC). The effect of pH, time, carbon dose were examined along with isotherm studies. The application of these carbons were examined on colour removal of Dark green PLS from both effluent samples and synthetic samples. Comparison is made among the carbons for adsorption of the dye. Desorption studies were also carried out along with BDST studies. Mathematical equations have been designed for the wide range of applications.

[Improving textile sun protection by regular washing of clothing].

The highest priority in the prevention of malignant tumors of the skin is given to the avoidance of sun-induced reddening of the skin and sunburn at any age. The usual recommendation is to keep out of the sun between 11 am and 3 pm, wear a sun-hat and appropriate clothing, and use a sun screen (UV-A and UV-B) that doesn't wash off on exposed skin and when in the water. With regard to the wearing of clothing protecting against UV radiation, compliance must be expected to be low, since just such protective clothing (in particularthick, densely-woven materials) is unsuitable for the summer. Using detergents containing a UV absorber in the home wash, even light summer wear can be made to offer good UV protection.

Wearable textile biofeedback systems: are they too intelligent for the wearer?

The Intelligent Knee Sleeve is a device capable of providing immediate audible feedback to the wearer pertaining to knee flexion angle during human movement. The Intelligent Knee Sleeve was used in a landing training program to determine whether providing subjects with this form of feedback was able to effect a change in knee flexion angle during dynamic landing tasks. Preliminary results suggest that the feedback modality is effective in correcting landing technique. However, advancements in the Intelligent Knee Sleeve design would produce a more robust system leading to more effective biofeedback for the athlete.

[Usefulness of questionnaires in detection of early symptoms of sciatica and related pain syndromes of the lumbosacral region and determination of their incidence among workers of textile industry].

The study was aimed at the determination of sciatica case rate among cotton industry workers based on inquiry. Two questionnaires for detecting complaints typical of sciatica were developed. 2463 weavers and 3083 spinners were examined. A comparative group involved 978 shop attendants and 593 office workers. It was found out that pains characteristic of sciatica were experienced by 45% weavers, 43% shop attendants, 29.2% spinners, and 16% office workers. Results of physical examinations in randomly selected cases corresponded in 97% with the questionnaire data. In most cases pains resulted from overloading of the lower section of the vertebral column.

Electron beam treatment of textile dyeing wastewater: operation of pilot plant and industrial plant construction.

A pilot plant for treating 1000 m3/day of dyeing wastewater with e-beam has been constructed and operated since 1998 in Daegu, Korea together with the biological treatment facility. The wastewater from various stages of the existing purification process has been treated with an electron beam in this plant, and it gave rise to elaborating the optimal technology of the electron beam treatment of wastewater with increased reliability for instant changes in the composition of wastewater. Installation of the e-beam pilot plant resulted in decolorizing and destructive oxidation of organic impurities in wastewater, appreciable reduction of chemical reagent consumption, in reduction of the treatment time, and in increase in the flow rate limit of existing facilities by 30-40%. Industrial plant for treating 10,000 m3/day each, based upon the pilot experimental result, is under construction and will be finished by 2005. This project is supported by the International Atomic Energy Agency (IAEA) and Korean Government.
