Abstract in Portuguese
O trabalho investiga a influencia dos parametros de processo: relacao D/Y e numero dos discos do agregado de texturizacao nas propriedades de frisagem dos filamentos de poliester texturizados por falsa torcao. Sao realizados ensaios numa texturizadeira industrial simulando diferentes niveis dos fatores D/Y e numero de discos.Analises estatisticas sao apresentadas e comprovam a influencia dos fatores nas caracteristicas de frisagem com nivel de confianca de 5%. Verifica-se que a combinacao de D/Y elevado com numero de discos elevado aumenta os valores dos parametros de frisagem do fio texturizado.

Abstract in English
The work investigates the influence of process parameters: the factor D / Y and the aggregate number of disks in the texturing properties crimping of textured polyester filaments for false twist. Tests were performed in an industrial texturing machine simulating different levels of factors D / Y and number of discs. Results of statical analyses are presented and show the influence of factors on the characteristics of crimping with a confidence level of 5%. It is found that the combination of D / Y with a high number of discs increases the high values of the parameters of the crimp textured yarn.
