Mathematical Modeling of Yarn Dynamics in a Generalized Twisting System
Twisting is an important process to form a continuous yarn from short fibres and to determine the structure and properties of the resultant yarn. This paper proposes a new theoretical model of yarn dynamics in a generalized twisting system, which deals with two important phenomena simultaneously, that is, twist generation and twist propagation. Equations of yarn motion are established and the b...
متن کاملImpact of Carding Parameters and Draw Frame Doubling on the Properties of Ring Spun Yarn
The impact of card cylinder speed, card production rate and draw frame doubling on cotton yarn quality parameters was investigated by using the BoxBehnken experimental design. It was found that yarn tenacity, elongation and hairiness increase by increasing the number of draw frame doubling up to a certain level and then decrease by further increase in doubling. Yarn unevenness increased by incr...
متن کاملEffect of Fibre Blend Ratios on Yarn Properties
Yarn properties can be altered through blending fibres. According to the requirement different properties can be achieved by different blending ratios. Among the different blends cotton and polyester, cotton and wool, wool and acrylic, cotton and nylon, jute and acrylic, cotton and rayon etc are common. Flax and polyester has been a popular blend now-adays and depicts excellent properties than ...
متن کاملPERFORMANCE OF IRANIAN CHILDREN ON THE DRAW-A-MAN TEST
In this study, the Draw-A-Man Test was administered to 183 Iranian children, 96 boys and 87 girls from age of 36 to 119.5 months. The subjects were selected randomly from middle-class families in Tehran. The results show that younger Iranian children scored higher than the older ones. In addition to the age differential on performance, sex differences on drawing a man were tested by means ...
