Abstract

"SISTEMA DE LIMPEZA QUE UTILIZA UM SOLVENTE DE LIMPEZA ORGáNICO E UM SOLVENTE FLUIDO PRESSURIZADO". é revelado um sistema de limpeza que utiliza um solvente de limpeza orgânico e solvente fluido pressurizado. O sistema não possui ciclo de secagem com ar quente evaporativo, convencional. Em vez disso, o sistema utiliza a solubilidade do solvente orgânico em solvente fluido pressurizado bem como as propriedades físicas de solvente fluido pressurizado. Após um ciclo de limpeza com solvente orgânico, o solvente é extraído dos artigos têxteis em alta velocidade em um tambor giratório (112, 122) da mesma forma em que os solventes convencionais são extraídos dos artigos têxteis em máquinas de limpeza seca com ar quente evaporativo, convencionais. Em vez de prosseguir para um ciclo de secagem convencional, os artigos têxteis extraídos são então imersos em solvente fluido pressurizado a fim de extrair o solvente orgânico residual dos artigos têxteis. Isto é possível porque o solvente orgânico e solúvel em solvente fluido pressurizado. Após imersão dos artigos têxteis em solvente fluido pressurizado, solvente fluido pressurizado é bombeado do tambor (112, 122) . Finalmente, o tambor é despressurizado até a pressão atmosférica para evaporar qualquer solvente fluido pressurizado restante, fornecendo artigos têxteis isentos de solvente, limpos. O solvente orgânico é selecionado de preferência de terpenos, haloidrocarbonetos, certos éteres de glicol, polióis, éteres, ésteres de éteres de glicol, ésteres de ácidos graxos e outros ácidos carboxílicos de cadeia longa, álcoois de cadeia longa, álcoois graxos e outros álcoois de cadeia longa, álcoois de cadeia curta, solventes apróticos polares, siloxanos, hidrofluoroéteres, ésteres dibásicos e solventes de hidrocarbonetos alifáticos ou solventes similares ou misturas desses solventes e o solvente fluido pressurizado é de preferência dióxido de carbono adensado.
