Abstract
The quality of woven terry fabrics is a phenomenon that requires successfully meeting several properties at the same time; among these properties are water absorbency, comfort, compressional resilience and performance and tailorability (FAST System) and handle and appearance properties (KES System). Very little study has been carried out on multiple properties and parameters at the same time. In this study, we used Response Surface Methodology (RSM) to optimize levels of pile height, picks density and weft yarn linear density using (Simplex Lattice Method) as a type of (Mixture Design). The results predicted by (the factorial design method) were found in a good agreement with the experimental results indicating the applicability of proposed model. A set of mathematical models expressed by contours plot was obtained for predicting water absorbency, comfort, compressional resilience and performance and tailorability properties, adding to this, handle and appearance properties of woven terry fabrics (KES System) as a function of pile height, picks density and weft yarn linear density. Those fabric, figures were optimized by first graphical approach based on overlaid contour plot and second by mathematical solution approach (3-Equation Solver System Software algorithm) which is applied to a number of constrained optimization and engineering design problems. The analysis of variance (ANOVA) is also applied to investigate the effect of significance of manufacturing parameters. Finally, the confirmation experiment was conducted for the optimal machining parameters, and the betterment has been proved. In this thesis, we used the Generalized Weighted Desirability Function method, Multi-criteria Decision Making method, Complex characteristics method and Polygon Area method to determine the best sample (Sample No.1) and worse one (Sample No.2). The predicted optimum conditions of the best sample No.(1) can be achieved at pile height code equals to (130), picks density per cm equals to (15) and weft yarn linear density equals to (16Ne). The KES (Kawabata Evaluation System for fabrics) is used for the measurements of low stress tensile, shear, bending, compression and surface properties. A new proposal for the objective evaluation of primary handle is presented by which the necessary and sufficient number of primary handle terms and the corresponding total primary handle values are obtained. The methods and results of determining and testing the physical meanings of these primary handle terms are also provided. Four primary hand equations and one total hand value equation (THV) have been developed using low-stress mechanical properties of terry fabric. It is observed that the objective hand values calculated by the newly developed hand equations correlate very well with the total appearance Value (TAV). Also, it is observed that fabric formability, elastic potential and drapeability can predict the appearance behaviour of terry fabric. The influence of constructional factors on the cotton woven terry fabrics hand is quantified by total hand value (THV) , total appearance values (TAV) and general quality factor (GQF). The principle measurements of the KES-FB and the FAST System are clearly explained, as well as the use of the interpreted data. An alternative approach which is more simple, inexpensive and reliable for objective hand evaluation has been suggested to replace all the previous equipment. Lastly, the applications of fabric objective measurements in the field of woven terry industries were highlighted.
