13. Aplicação de ciclodextrinas em processos têxteis
Cyclodextrins (CDs) are water soluble cyclic sugars with a hydrophobic nanometric cavity that permits the formation of host/guest inclusion complexes with a large variety of molecules, alternating their physical-chemical properties. In the present review CD research related to the processing of textiles is revised and discussed. CDs may function as encapsula

14. Electrospinning and characterization of polyamide 66 nanofibers with different molecular weights
Polyamide 66 (PA66) nanofibers of different molecular weights were obtained by electrospinning of formic acid solutions. An ionic salt, NaCl, was also added to the solutions to increase the conductivity. PA66 concentrations between 15-17 wt.(%)/v and electrical fields between 2.0 and 2.5 kV/cm were the best conditions to produce the smallest nanofibers; howe

15. Effect of textile waste on the mechanical properties of polymer concrete
The mechanical behavior of polymer concrete reinforced with textile trimming waste was investigated. Two series of polymer concrete formulations were studied, with different resin/sand (i.e. binder/fine aggregate) weight ratios. In each series, recycled textile chopped fibers at 1 and 2% of the total weight was used. Flexural and compressive tests were perfo

16. Avaliação da biodegradabilidade de efluentes têxteis do beneficiamento secundário de malhas de poliéster tratados com Reagente de Fenton
From the environmental point of view, the textile sector is outstanding for the generation of large amounts of biorecalcitrant effluents. In this paper the textile effluent biodegradability, both before and after its treatment with Fenton's Reagent, were compared by means of biologic tests. These tests showed that the Fenton treatment lowered the biodegradab

17. Reticulação de compostos poliméricos para recobrimento de superfícies
Coating of cotton fiber is employed in the textile industry in order to increase the mechanical resistance of the yarns, that is, resistance to vibration, friction, impact and elongation, which are some of the forces the yarn is subjected during the weaving process. The choice of the coating material is extremely important, since it can provide the best perf

19. Effects of the end of the Multifibre Agreement on production and employment in the textiles and clothing sectors in Brazil / Efeitos do fim do Acordo Multifibras sobre a produção e o emprego dos setores têxtil e de vestuário no Brasil
The importance of the textile and clothing industry is based on its high capacities to generate employment and income, provided its basic characteristic of reduced ability to automate the production processes. Besides that, these sectors are responsible for an important share of the low qualified jobs in the developed countries. Therefore, the industries ach

21. 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
