Investigation on the possibilities of enzymes usage in the pretreatment of cotton woven fabrics and combined process development [Pamuklu dokuma kuma{thorn}larin boyamaya hazirlik ý{thorn}lemlerýnde enzým kullanim olanaklarinin ýncelenmesý ve kombýne proses gelý{thorn}týrýlmesý]

In this study,usage of enzymes in the pretreatment of 100 % cotton woven fabrics was investigated. besides,possibilities of shortening the process with the usage of amylase and pectinase in the same bath and using laccase in the bleaching treatment were investigated. for this aim,after each treatment,desizing degree,hydrophilic characteristic and whiteness degree of samples were studied carefully. furthermore,the pretreated fabrics were dyed at three concentrations (owf%). after dyeing processes,the cielab values and the fastness properties were also researched. the results showed that application time,water,energy can be saved by using the amylase and pectinase in the same bath,the laccase enzyme is not sufficient for fabrics which are dyed at light shades.
