Principle Component Analysis map of products Plain weave waved twill crêpe and 12-satin have very distinguished tactile profiles as compared to the other fabrics. Knowing the correlations that may exist between fabric pattern and tactile properties manufacturers would be able to design specific touch by the weaving process instead of using finishing treatments. This may be interesting in order to develop an environmental friendly process and avoid the use of chemical products. Effect of the yarn count on the fabric hand of cotton woven fabrics All woven fabrics are made by yarns. It is therefore interesting to study the effect of yarn properties on fabric hand. In this paragraph on yarn property the yarn count is studied. The impact of this factor on fabric sensory properties is underlined. Materials The study is carried out on 4 fabrics having different weft counts 25 Tex 50 Tex 71 Tex and 100 Tex. The other parameters are unchanged 100 cotton Warp count 14 Tex and Index of saturation 52 . The experiment is applied on nine different patterns. Only the results of the plain weave are presented in this paragraph. Results and discussion The ANOVA 2-way test 5 revealed that 9 attributes are significantly affected. These attributes are thin-thick light-heavy supple-rigid soft granulous grooved falling responsive and elastic. The sensory profiles are presented in Figure 12. It can be noticed that some attributes are positively correlated to the yarn count. These attributes are thin-thick light-heavy supple-rigid granulous and responsive. On the map of products obtained by the Principle Component Analysis Figure 13 it can be noticed that fabrics are ranked on one .
