EVALUATION OF THE WEAVABILITY OF SIZED COTTON WARPS

Abstract

In weaving, a warp must withstand repeated stretching, caused by shedding and beat-up. It is also subjected to abrasion, which is mainly due to shedding and reed motion. The yarns are therefore sized. Two important reasons for applying sizes to spun warp yarns are to protect them breaking during weaving and to decrease their hairyness so that the tendency for adjacent warp yarns to entangle will be reduced. In this work, we investigated the weaving performance and physical properties of cotton yarn sized at high pressure squeezing. We studied the size penetration, film properties, and the yarn packing density in order to explain the performance of sized yarn.
