In this research, 4 types cotton fabrics(20's, 40's, 60's, 80's), NaOH, Yellow86, Yellow11, Blue15, Black19 of 4 direct dyes, high temperature type of 1 reactive dye and lower temperature type(BF, VS) of 2 reactive dye. were used. Also, NaOH as reagent for mercerization, Na2CO3 and Na2SO4O for dyeing were used. The results of this research are as follows.
The optimum temperature was 20℃, optimum concentration was 20-30g/100cc, and optimum treatment time was 2-3 min.
The contractility of 40's cotton fabric that is mecerized had large scale rather than non-mecerized fabric.
The tensile strength of mercerized fabric was improved about 12-25%. and the absorbency of mercerized fabric was improved 17%-35%.
The ripples of fabric was most effective on 80's and then the order was 60's, 40's and 20's. But the easy and beautiful ripple was created on 60's.
The dyeability of mercerized fabric was improved over about 20-30% rather than non-mercerized fabric. In dyed fabric of before and after mercerization, change of the color was not produced. After mecerization color fastness of dyed fabric to washing, solvent and day light was improved about 1 grade.
The part of crystallization of mercerized fabric was decreased about 30% as compared with non-mercerized fabric and the more the treatment concentration was high, the more the cracks were produced on surface of fabric.
The maypro-gum was most effective as binder for mercer-printing, the optimum concentration was 4-5%.
