An investigation into the factors involved in preparation and weaving affecting the length and width of woven cloth : effect of warping and weaving tensions, warp control devices, and relaxation processes on warp and weft modular length and thread spacings : the influence of beat-up force and cloth-fell distanceBasu, Asok Kumar January 1980 (has links)
So far the theoretical approach to weaving resistance and fabric geometry and the factors affecting it have been made for such weaves as plain, hop-sack and warp and weft faced ribs. In this work theoretical models were adopted to determine the fabric geometry and weaving resistance. Experimental and theoretical findings are in agreement. The trends of the effects on values of weaving resistance of such factors as warp elastic constant, weft tension, warp tension, the coefficient of friction of yarn against. yarn agree with the trends obtained by other workers by showing that weaving resistance increases with these factors. The results-also show that-the fabric geometry depends on warp and weft tension at-the moment of beat-up. Additionally, the change of fabric geometry across the fabric, the effect of two different let-off mechanisms,, Hattersley and WIRA/Poole, and the beaming CO processes on weaving resistance and fabric geometry were investigated. It was found that the fabric width-depends on the dynamics of fabric formation before and at the moment of beat-up.
