Abstract: A method of arriving at the square setting of woven fabrics is reported. An attempt has been made to relate cloth setting limits with the rate of production (the rate of production decreases as weft density in the fabric increases) as controlled in the case of negative let-off motion during weaving. Taking the existing cloth setting theory to be applicable in mill practice, a criterion for comparing setts is evolved and a possible practical relationship for obtaining the maximum practical loom sett in the case of corkscrew woven fabrics is deduced. Samples have been woven using 72S, 80S and 88S reeds, in each case running a series of different weft setts, reaching up to the maximum possible sett. Three weft cotton counts, 2/20S, 2/40S and 2/60S, with 2/40S warp count (polyester-viscose blend for each, 48:52) were used. Weft corkscrews (2/2,4/4,3/4,4/5 and 5/6) and warp corkscrews (4/3, 5/4 and 6/5) were woven. In each case, the cloth fell distance was measured on the loom during weaving. In all the cases, limits for maximum setts have been determined and the values compared with those obtained by Law [Wool Rec Text Wid, 21 (1922) 968] and Brierley [Text Mfr, 57 (1931) 3; 50(1932) 178,342; 78(1952) 349, 431, 437, 449,595; 79(1953) 71, 189, 283].
