Abstract
The present study was conducted to study the enzymatic scouring of cotton yarn. Scouring was
done with palkoscour APCL bioscouring enzyme. To achieve better result for enzymatic scouring
standard conditions was determined i.e. 0.5% dosage at 550C temperature with 7 pH for 40 minutes.
After scouring physical properties of unscoured and scoured yarn regarding linear density, lea strength,
count strength product, yarn tensile strength, yarn elongation, yarn evenness, twist per inch, crimp
rigidity and yarn hairiness were also studied. Next step was done to treated unscoured and scoured
cotton yarn with four dyes viz. direct dye, reactive dye, basic dye and azoic dye. After the process of
dyeing again physical properties of unscoured dyed and scoured dyed yarn were measured. Effect of
dye color strength on unscoured and scoured yarn was studied through CIE LAB values. It is thus
summarized that with the help of determined conditions enzymatic scouring was done. After enzymatic
scouring physical property of grey yarn changed as compared to scoured yarn. Linear density of treated
yarn and yarn tensile strength decreased after scouring. Yarn evenness and yarn hairiness was
improved. after process of dyeing hairiness and evenness of dyed yarn improved but strength decreased
more. CIE LAB values indicated that direct and reactive dye scoured yarn was darker, redder and
brighter. Basic dye scoured yarn was darker duller than unscoured yarn azoic dye scoured yarn was
lighter, redder, yellowier and brighter. Color strength of azoic dye was higher than direct reactive and
basic dye.
