BRIEF NOTE ABOUT FABRIC MERCERIZATION MACHINE: Mercerization and it importance: Impregnation of Cotton, in the form of yarn or fabric, with sodium hydroxide solution (caustic soda) at a concentration in the range 200-220 gpl (grams per litre) at 20°C or 60°C under certain tension is called mercerisation.
Mercerizing with. Ammonia. Even if the textile world remains hesitating because it is not really familiar- ized with the problems of the use of ammonia, these are now mastered thanks to the collaboration between ammonia producer and textile finishers. It may be seen further in this paper why the use of ammonia in textile.
Extensive research work has been carried out on yarn and fabrics. It is reported in various journals by research workers [149 - 124]. However, very less research work is available on mercerization of compact yarn fabric. It has been found recently that hot mercerization by Caustic Soda gives better Comfort properties to the

Typical pretreatment of cotton involves. 1. Singeing. 2. Desizing by conventional /enzymatic process. 3. Scouring by conventional /enzymatic process. 4. Bleaching. 5. Neutralization. 6. Peroxide removal. 7. Bio-polishing. 8. Mercerizing. 9. Optical Brightening
18 Mar 2010 In this study, mercerization processes were performed on cotton fabrics with three different weaving patterns in chain mercerizer at 60°C by applying three different time periods and three different processes under factory conditions. The fabrics, which were weaved from 20/1 open-end and 100%.
The Mercerizing Process it 'a chemical-physical treatment applied to the polymer chain of cellulose fibers, such as cotton, linen, hemp and all their compositions where the cellulosic fibers are prevalent in the formation of the yarn. - Chemical, exothermic chemical per serving in the cellulose chain through a caustic fluid.
BACKGROUND. Mercerization is a process in which textiles (typical- ly cotton) are treated with a caustic (NaOH) solution to improve properties such as fiber strength, shrink- age resistance, luster, and dye affinity. The caustic actually rearranges the cellulose molecules in the fiber to produce these changes. Higher-end
20 Feb 2012 Mercerizing is done after bleaching operation. Bleaching is enough for prepared the fabrics for dyeing and printing but mercerizing is done for adding some advantage to the fabric. Luster and strength of the fabric increases for mercerizing process. Cotton mercerizing is the most popular operation.
