Abstract in Portuguese
Este projeto, "Influência do fator de cobertura nas propriedades de permeabilidade de tecidos planos", descreve um breve histórico sobre a Tecelagem e seu crescimento na indústria Têxtil mundial, sendo muito importante o seu desenvolvimento para a indústria. Será apresentado também o conceito sobre Fator de cobertura de tecidos planos. Com o objetivo de avaliar a correlação entre o fator de cobertura e a permeabilidade dos tecidos planos, foram desenvolvidas 18 amostras de tecido com fio 60/2 Ne 100% agodão no urdume e na trama, em ligamento tela, sarja e cetim com densidades de trama 16tramas/cm, 24tramas/cm e 32tramas/cm, e com densidade de urdume 16fios/cm e 32fios/cm . Foi calculado o fator de cobertura para todas as amostras e foram realisados ensaios de gramatura, permeabilidade ao ar, permeabilidade ao vapor de água e permeabilidade a água, com a observação do indice OMMC (Capacidade de gestão global de umidade) do aparelho MMT (Moisture Management Tester). Este estudo se mostra como um caminho na Utilização do fator de cobertura, como item a ser considerado no desenvolvimento de novos artigos. Os resultados mostram para cada ligamento e fator de cobertura o comportamento com relação à permeabilidade dos Tecidos

Abstract in English
This project, "Influence of the coverage factor on the properties of permeability of woven", describes a brief history on Weaving and its growth in the world textile industry, being very important its development for the industry. The concept of woven coverage factor, will also be presented. In order to evaluate the co-relation between the coverage factor and the permeability of woven, 18 wovens samples were developed with 60/2 Ne 100% cotton thread in the warp and the weft, inwoven twill and satin weave with warp weights 16 yarn/cm, 24 yarn/cm and 32 yarn/cm and with warp density 16 yarn/cm and 32yarn/cm. The coverage factor was calculated for all samples and weight, air permeability, water vapor permeability and water permeability tests were performed with the observation of the OMMC (Global Moisture ManagementCapacity) index of the MMT (Moisture Management Tester).This study shows as a path in the use of the coverage factor, as an item to be considered in the development of new articles. The results show for each ligament and cover factor the behavior regarding the permeability of the wovens
