2. Estudo comparativo do tingimento de malha PES/CO com água tratada com resíduo de clarificação de óleo vegetal, na forma natural e calcinada
RESUMO A indústria têxtil utiliza um grande volume de água, o que torna necessário encontrar opções mais sustentáveis para o seu uso, como a reutilização em novos tingimentos. O uso de um resíduo industrial sólido, como adsorvente, poderá ser uma alternativa para tratar o efluente têxtil. Este estudo teve como objetivo testar a viabilidade do re

3. The influence of heat treatment on the quality of screen printed textile substrates
ABSTRACT During exploitation, textile products printed with screen printing technique are quite often exposed to various influences, one of which is a heat treatment- firstly during the production process and later on when ironing. Heat is simultaneously affecting deposited colorants (ink) on the surface of the substrate material, as well as textile fibers i

4. Behavior in simulated soil of recycled expanded polystyrene/waste cotton composites
Composites consisting of waste cotton yarn (CF) from the textile industry and postconsumer expanded polystyrene (EPS) was followed during 90 days of exposure in simulated soil. The mechanical properties, morphologies and chemical natures of the composites were determined before and after exposure in simulated soil. The composites were made using a single-scr

5. A relação cidade-campo em Campina Grande a partir da produção do algodão colorido.
The ancient city-country dichotomy has been diluted with the news changes, making a dialectical unity between these two spatiality. The news relationships city-country is based in exchange of information and technology by the city. Its creates a new agricultural activities arrangement. With this changes arises the scientific agriculture, guide to market econ

7. Reuso do efluente do processo de mercerização no tingimento de malha de algodão
The water consumption tendency increase with the increasing industrial activity and in specific, the textile area has been worring about this natural resources, once the water is a finish resource in our planet and its consumption in the areas how finishing process represents approximately 90% of the general consumption on this industry. The creation of envi

8. Treatment corona on surfaces textiles / Tratamento corona sobre superficies texteis
Amongst the techniques of modification of surfaces applied in the industry to improve adhesion, the treatment for discharge corona widely is used. During the treatment for discharge corona, active species are generated, which can consequently react with the surface of polymer causing chain in addition and formation of radicals, thus creating polar groups in

9. Color s reduction of black liquor from cotton s cellulose production, using oxidation by ozone at basic environment / Redução de cor do licor negro da industria de celulose de algodão com a utilização de ozonio em meio basico
Através da utilização de ozonização em meio básico, foi desenvolvido um processo de oxidação para a redução de cor em licor negro gerado na obtenção de celulose de algodão, que demonstrou ser mais econômico por reduzir o consumo de ozônio comparativamente ao processo de ozonização simples. Usando o ozônio em meio básico, gerou-se radicais

11. Anthonomus grandis Boheman (Coleoptera: Curculionidae) en la zona central y sur oeste de misiones, Argentina: polen como fuente alimenticia y su relación con el estado fisiológico en insectos adultos
Host feeding plants of adult boll weevils (Anthonomus grandis Boheman) were determined within the period: January 1997 - December 1999. This took place through the identification of pollen grains, isolated from the digestive tracts of boll weevils captured in pheromone traps placed in a transect line which passes through the localities of Montecarlo, San Ign

12. Caracterização de Efluente Têxtil e Proposta de Tratamento
Textile industry deals with a high diversity of processes and generation of wastewaters with a high content of pollutant material. Before being disposed of in water bodies, a pre-treatment of the effluent is carried out, which is sometimes ineffective. In order to be properly treated, physical and chemical properties of the effluent must be known, as well as
