About tweenty years ago, the hybrid effects in blended yarns were investigated, and this was followed by a fewpublications on the hybrid effects in polyester cotton blended yarns. The results obtained from the work done showed thatsome of the analysis done was found to be imprecise and were not found to be correct. This paper reports an investigation ofthe prediction of blended yarn properties from the constituents by a hybrid model which has been formulated. Previousresearch workers used different methodologies which were fraught with many imprecisions. The methodology followed in thepresent investigation gives precisely the parameters, their interactions together with their significance levels. The interactionvalue can be simply obtained from quadratic regression model avoiding the use of equations given by various authors. Noproper linear regression analysis was done on the data by the previous research workers and thus there were manyimprecisions which were noticed. Five blends of yarns comprising of bamboo and cotton namely, 100% bamboo, 75%bamboo and 25% cotton, 50% bamboo and 50% cotton, 25% bamboo and 75% cotton and 100% cotton were produced andthey were tested for tenacity, elongation, evenness, imperfections and friction. Both quadratic and linear regression analyseswere performed. The linear regression analysis which was conducted meticulously unlike the previous authors showed thatthe values were significant. Interaction values were found to be significant for elongation, thin and thick places. It was foundthat tenacity of bamboo cotton/ blended yarns fell upto 75% bamboo and rose thereafter. Elongation of bamboo/cottonblended yarns was found to increase with increase in bamboo content. An improvement in U% and imperfections and frictionwas noticed with increase in bamboo content.
