Continuous Process for Alkali Treatment of Polyester/Cotton Fabric
Treating in alkali condition is one of the methods used for improving the polyester fabric properties.Several researchers have studied on batch processes for alkali treatment of polyester and polyester/cotton fabric and no research have been reported about any continuous process for this treatment.In this study a padsteam process for alkali treatment of polyester/cotton fabric has been developed and the effect of alkali on polyester/cotton fabric has been investigated.Furthermore the traditional batch process and the new continuous one have been compared.The pad-steam process has the advantage of less treatment time,low treatment costs due to less water and chemicals needed and thus is safer to the environment.In order to reach the utilized weight reduction without damaging the fiber structure and optimizing the chemicals and treatment time,certain auxiliary product such as quaternary ammonium salt which can be considered as a hydrolysis accelerating agent,besides caustic has been used.Some characteristics of alkali-treated fabric such as tenacity,crease recovery angle,bending length and water absorbency have been measured.Finally the best process,giving the best result as far as water absorbency,handle with the lowest damaging to the physicochemical properties of the fabric has been evaluated and indicated.
