Abstract: | Abstract In this work the effect of cotton yarn properties on yarn end breakage was investigated. The yarn nominal linear densities were 20, 25 and 36 tex and each of them, had three levels of twists. Following yarn properties were investigated: linear density, twists, tensile strength, elongation at break and irregularity. Standard methods were applied to determine these yarn properties and hronometric method for yarn end breakage was used. It was only the yarn linear density, among all yarn properties, that showed significant correlation with yarn end breakage (-0,75 to -0,96). It was shown that about 80% of all yarn end breakage are occurred in places with fineness lower than average cross section of the yarn that point out that the thin places of the yarn are inclined to breaking. Also, the mutuality effect of geometrical characteristics and physical-mechanical properties of the yarn on end breakage was investigated. |
