25. Reuso de soluções de corantes básicos, pós-tratamento fotoeletroquímico, para tingimentos de fibras acrílicas
The increasing contamination of natural water resources is gaining public attention and has roused environmental concern in the society. As the second richest country in water resources, Brazil has an abundant supply of water, but it lacks a good management plan for these resources. It is estimated that by 2025, the industry will be responsible for 24% of th

26. Fatigue damage mechanism and failure prevention in fiberglass reinforced plastic
Damaging of composite laminates was monitored during fatigue tests, revealing the formation and propagation stages for compressive, tensile, or alternate cyclic loading. Two different laminate stacking sequences, with different number of layers, were tested. The laminates consisted of E-glass fibers reinforced orthoftalic polyester resin (FGRP) shaped as mat

27. "Compósitos de fibras de sisal para uso em reforço de estruturas de madeira" / Sisal composites to reinforcement of timber structures.
Many buildings of cultural and historical interest require reinforcement of their timber structures. This research focuses on fiber-reinforced composites to repair and reinforce such structural elements of wood as an alternative for carbon and glass fibers, which are the materials most commonly used for purposes of reinforcement. Natural fibers are an import

28. O fio sintetico e um show! : moda, politica e publicidade; Rhodia S. A., 1960-1970
This study aims to analyze the politics of advertising used by the Textiles Division of Rhodia S.A in Brazil, between 1960-1970. The advertising campaings were elaborated for Lívio Rangan (then managing of advertising of the company), and were executed by a team of professionals at Standard Propaganda, in order to create taste and to popularize the use of s

30. PHOTOREACTORS EVALUATION BY THE DEGRADATION OF REACTIVE DYES AND TEXTILE EFFLUENT / AVALIAÇÃO DE FOTORREATORES NA DEGRADAÇÃO DE CORANTES REATIVOS E EFLUENTE TÊXTIL
The continuous search for better quality of life, nowadays, implies in industrial growth e, consequently, in greater or minor degree of environmental pollution. The textile industry is responsible for part of this pollution; among the several environmental problems generated by the textile industry, two are distinguished: the not setting of dyes on the fiber

31. Preparação, caracterização e aplicação de membranas de poli (fluoreto de vinilideno) para a redução de cor de efluente textil modelo
The textile industry processes deal with many different materiais being responsible for a large volume of potential pollutant streams, mainly due to losses of dyes occurring during the dyeing process of the fibers, which are discarded in the effluent. Membrane separation processes are considered potential good new alternatives for the treatment of textile ef

32. Corantes têxteis
A dye is a colored substance used to impart permanent color to other substances. Its most important use is in coloring textile fibers and fabrics. The removal of colour from dyehouse waste waters is currently a major problem in the textile sector. This paper provides an overview of the treatment technologies that can currently be used by the textile processo

33. Metabolic pathway engineering in cotton: Biosynthesis of polyhydroxybutyrate in fiber cells
Alcaligenes eutrophus genes encoding the enzymes, β-ketothiolase (phaA), acetoacetyl-CoA reductase (phaB), and polyhydroxyalkanoate synthase (phaC) catalyze the production of aliphatic polyester poly-d-(−)-3-hydroxybutyrate (PHB) from acetyl-CoA. PHB is a thermoplastic polymer that may modify fiber properties when synthesized in cotton. Endogenous �

34. Suppression of Sucrose Synthase Gene Expression Represses Cotton Fiber Cell Initiation, Elongation, and Seed Development
Cotton is the most important textile crop as a result of its long cellulose-enriched mature fibers. These single-celled hairs initiate at anthesis from the ovule epidermis. To date, genes proven to be critical for fiber development have not been identified. Here, we examined the role of the sucrose synthase gene (Sus) in cotton fiber and seed by transforming

35. Quantitative Studies on Fabrics as Disseminators of Viruses: I. Persistence of Vaccinia Virus on Cotton and Wool Fabrics
The persistence of vaccinia virus on wool (blanket and gabardine) and cotton (sheeting, terry cloth, and knit jersey) fabrics was studied. The fabrics were exposed to the virus by three methods: direct contact, aerosol, and virus-containing dust having a high content of textile fibers. Fabrics exposed to virus by each method were held in 35 and 78% relative

36. Factors Affecting the Persistence of Staphylococcus aureus on Fabrics
The persistence of Staphylococcus aureus (Smith) on wool blanket, wool gabardine, cotton sheeting, cotton knit jersey, cotton terry cloth, and cotton wash-and-wear fabrics was studied. The fabrics were exposed to bacterial populations by three methods: direct contact, aerosol, and a lyophilized mixture of bacteria and dust having a high content of textile fi
