The flux of Bolivian migrants to the city of São Paulo had its beginning in the 1950 decade, following bilateral agreements between Brazil and Bolivia, and was intensified since the beginning of 1980 decade, when existed a necessity of manpower in the textile sector of the city. The migratory fluxes previously stemmed of the North and Northeast regions of the country become less intense, having then the entrance of migrants coming from neighboring countries, the so called South Cone. The Bolivians leave their country in the search for better life conditions and find in São Paulo the possibility to insert them in the biggest concentration of financial capital in the Latin America. The objective of this research is to analyze the arrival of the Bolivian migrants to the city, having its locus of analysis the Brás region and the reflection about the foreigners that influenced the modification of the structure, both territorial and cultural, of the district and how is the relation between the Bolivians and the habitants previously established there

In this work polymeric composites reinforced with cotton fibers, from the textile industry, were developed in order to manufacture printed circuit boards. It was used expanded polystyrene (EPS) as a thermoplastic matrix by melting it. For the obtention of 10% and 15% of fiber volume fraction in cotton fibers composites, it was used wasted cotton fibers as an incentive of recycling and reusing of the domestic and industrial wastes as well as for Expanded Polystyrene(EPS). The mechanical properties of the composites were evaluated by tensile and flexural strength from standardized test methods. Composites were characterized by a Scanning Electron Microscopy (SEM), Thermogravimetry (TG/DTG), Differential Scanning Calorimetry (DSC) and dielectric analysis. The analysis of the results showed that fiber in the composite directly influenced in the thermal and mechanical properties

Due to an intense process of population growth and urban density in Americana (SP), mainly due to the development of the local textile industry after 1970, there was, concomitant to the occupation of the margin of rivers and streams, soil sealing that increased the level of superficial runoff, triggering frequent floods. Based on the analysis of these processes we investigate the conditions of one densely urbanized area of the county, the Córrego do Parque, in three time series, 1977, 1996 and 2008. Taking as the starting the characterization and spatial distribution of landscape physiography, we prepared thematic letters and synthetic maps digital scale 1:10,000 from photointerpretation of aeroframes. The thematic maps were produced by scanning with subsequent edition using the software Auto-Cad Map. Checking the data and of geographic coordinates with GPS (Global Positioning System). Regarding land use classes, we used the description of the Soil Conservation Service (1975) which allowed us to get the Curve Number parameter, which will be used in hydrologic modeling for verification of flooding (Tucci, 1989). For the process of hydrologic modeling, we used models based on Methodology Object Oriented Modeling Applied to Water Resource Systems, Viegas Filho (1999), using the computer program called IPHS1, which uses models of the Soil Conservation Service (SCS , 2004), for conversion of rainfall-runoff and the spread of excessive rain. The results indicate that increased waterproofing generated by the change in use and occupation over the past decades promoted the increased surface runoff and drainage system overload, increasing the intensity of floods

Founded in 1921, the company currently known as Lupo S/A is one of the most ancient textile and clothing industries in Brazil. In this article we aim to describe the general lines of the trajectory of this family company, currently producing socks, nightwear and sports articles. The focus of this paper is on the analysis of some strategies used by the company along its formation and development process, and, particularly, the way these strategies made possible the productive restructuring associated to the overcoming of the strong crisis which began in the end of the 80's and early 90's, contributing to its recent consolidation in the clothing industry. The leading hypothesis of the study is that pioneering connected to a strong organizational culture that has been formed and constructed since its foundation and that was reestablished in a more recent management were the factors which were responsible for the advances able to generate an innovation environment in products as well as in processes and management. The theoretical reflection selected to subsidize the cognitive construction of the study of the company is based on the historical approach of the development of the textile industry in Brazil and in studies about the importance of the action of the entrepreneur, in the role of the organizational culture and of innovation to choose strategies in companies. The research involved the analysis of documents and data of the company, as well as interviews with directors and employees. The results show a traditional company model, but also show the presence of a very advanced entrepreneurial dynamic. Modern world – known as a fordist industrial model – could already be noticed in the company when this production pattern was not clearly defined yet in the Brazilian industry. Nowadays, the company faces the challenge of globalization and the open competition in the international market which brings the rivalry of the greatest and best globalized companies.

This article investigates the productivity and production function of thirteen large Brazilian textile and clothing companies before and after the end of the Agreement on Textiles and Clothing (AVT) that abolished import quotas in 2005. For this purpose, we estimate the stochastic production frontier in panel data between 1997 and 2008 and simultaneously an explanatory equation for the (in)efficiency of firms, as proposed by Battese and Coelli (1995). The results indicated that more efficient firms are the oldest. The total factor productivity of firms tended to fall, even after the end of quotas, increasing productivity only from 2007. Overall, firms from Santa Catarina were more efficient than those of other states.

One of the most primal ways of human work already known is the tessellation and ginning for the production of fabric and clothing - what used to be, back in those days, statement of power and status. The arrival of the Industrial Revolution - in the middle of the XVIII century at Britain - increased the textile industry production, and what used to be manufactured and hard to obtain, starts then to be produced in mechanical ways and large-scale. Despite all the boost given to the economy of an expanding capitalist market, it should be pointed out the consequences of this major industrialization, especially the environmental ones, more and more concerning nowadays. The emissions of waste - that sometimes could be toxic - in effluents can possibly contaminate the aquatic ecosystems, causing a huge damage to its fauna and flora, affecting therefore all the biodiversity, reaching inclusively the humans. To avoid these problems, a few strategies have been taking place in the attempt to eliminate - or at least reduce - the amount of dye found in the effluents, and as the textile industry constantly leaves waste, efficient methods - that present good results in a short period of time - with a low cost are needed. The present study will test the bioremoval capacity of yeast (Saccharomyces cerevisiae) in contact with dyes in a fix concentration, diluted in water with three different pH values. The tests will be done duplicate, and after the concentration analyses - made by spectrophotometry - it will be analyzed which pH shows major efficiency in the dye removal and what is the influence of the biomass in this process
