A study on the dyeing of sodium hydroxide treated polyester / cotton blend fabrics
نویسنده
چکیده
The polyester (100%), cotton (100%) and Polyester / Cotton blend fabrics (65 / 35; 50 / 50 & 35 / 65) were treated with sodium hydroxide followed by hydrophilic finishing and dyeing to impart hygroscopic and dyeing characteristics. Then the finished fabric was tested for k/s value, fastness properties, wetting behaviour, water retention, wicking behaviour and static charge respectively. The sodium hydroxide treated and hydrophilic finished fabrics show improved k/s value with good fastness properties (wash, light and rubbing), wetting, water retention and wicking behaviour that consequently leads for the reduction of static charge. The Polyester / Cotton blend fabrics after sodium hydroxide treatment and hydrophilic finishing showed very good improvement in these characteristics.

Combinative Scouring, Bleaching, and Cationization Pretreatment of Greige Knitted Cotton Fabrics for Facilely Achieving Salt-Free Reactive Dyeing.
In order to facilely achieve pretreatment and salt-free dyeing of greige knitted cotton fabrics, a combinative scouring, bleaching, and cationization pretreatment of the fabrics is designed in this study. The fabrics are first treated in a bath containing commercial scouring and bleaching agents, and then glycidyltrimethylammonium chloride (GTA) is directly added into the bath to achieve cation...
متن کاملHot Mercerizing of Cotton/Polyester Blend Fabric Effect of Alkali Treatment Temperature on Ttensile Properties , Weight Loss and Shrinkage of Fabric
The presence of defects in cold mercerizing of cotton goods led to the creation of a new method, called hot mercerizing in which caustic soda solution is used at a high temperature. Hot mercerizing is successfully used in cotton blended with some other fibers. In cotton/polyester blend fabrics, this treatment serves a dual purpose: subjectively, it imparts a silklike

Three sulfatoethylsulfone reactive dyes have been synthesized and were applied to mill desized, bleached and mercerized cotton fabric. Effect of different dyeing parameters i.e. salt concentration, dyeing time, dyeing temperature and pH of dye solution were being optimized by exhaust dyeing method. The fixation (%F) of the synthesized dye molecules with the cotton fabrics was also studied. Cott...
