Abstract: The present study was conducted to determine the
impact of cotton / polyester blending ratio, cotton type, yarn twist and yarn
count on yarn breaks on warping machine. Two-way ANOVA technique was used to
detect the significant effects of these variables on yarn breaks. Regression
analysis was used to predict the number of yarn breaks at different levels of
each independent variable. The findings of this study revealed that Blending ratio
of polyester in cotton:polyester blended yarns has a significant effect on yarn
breaks and the breaks associated with carded yarns were more than that
accompanied the combed ones. The number of yarn breaks varies directly with
single and plied yarn counts. Whereas twist multipliers inversely affect the
number of yarn breaks. For warp yarns of count 20 Ne, Yarns spun from Giza 70
exhibited higher breaks number, while for yarns of count 40 Ne, Giza 83 showed
higher yarn breaks. Singeing process enhanced warp yarn breaks on warping
machine by approximately 25%.
