About the Book

O autor deste livro investigou e documentou as propriedades de revestimentos de rolos de descaroçamento de algodão e os antecedentes do processo de descaroçamento com rolos. A maior parte das operações de descaroçamento do algodão são realizadas utilizando máquinas de descaroçamento com rolos duplos (DR) que desempenham um papel importante nas fábricas de descaroçamento. Os rolos utilizados nestas indústrias são geralmente feitos de revestimentos de Couro Composto de Couro Cromado (CCLC) fixos a um eixo. As coberturas CCLC contêm cerca de 18 000 a 36 000 mg/kg (ppm) de crómio. Quando o algodão de linho é processado em gins DR, o algodão de linho é contaminado com crómio de cerca de 140 a 1990 ppm como substância total de crómio, que é cancerígena em relação aos limites seguros de 0,1 ppm. Além disso, os trabalhadores das fábricas de gin e têxteis estão directamente expostos a esta substância carcinogénica e são vulneráveis aos riscos para a saúde. Para compensar este problema, foram fabricadas e experimentadas lavadoras/ rolos de tecido de algodão sem poluição (RCF), tanto para estudos laboratoriais como comerciais, que poderiam ser utilizadas comercialmente como alternativa nas indústrias de descaroçamento de rolos em benefício do ambiente, da sociedade, dos proprietários das fábricas, dos comerciantes, dos trabalhadores, dos empregados e do governo.
