The purpose of this study was to develop a new methodology of on-line optical spun yarn count analysis and control (OYCA) by use of on-line optical yarn diameter measurements and to carry out method comparison study against the ASTM D 1907 – 89. The result of the study showed sufficient agreement between OYCA and the ASTM D 1907 – 89. Inter-plant comparison of method difference was not significant, which is an indication of the robustness of OYCA across plants with similar technologies and process parameters. Significant predictive relationship between optical yarn volumes (OYV), twist and linear density was demonstrated by a factorial experiment where factors of twist and linear density were set at high and low levels of ±10 % augmented by center points from regular production set up. Optical fiber volumes in skeins were verified using gas pycnometer volume measurements. Significant correlation r (60) = 0.96, p / A Dissertation submitted to the Department of Retail Merchandising and Product Development in partial fulfillment of the requirements for the degree of Doctor of
