Abstract

The structure of nonwoven fabrics could be assessed by making use of a photometric method . The anisotropy of tested fabrics has been studied in terms of optical density (D) ; percentage transmission (% T) ; and percentage absorption (%A) , we have constructed an experimental set-up that is versatile to test and assess several fabric parameters of practical importance , as uniformity and isotropicity .
It was found that for tested fabrics the packing density coefficient (Ǿ) and percentage transmission (%T) are well correlated. The percentage transmission decreases with the increase of mass per unit area (G) , and the ranking correlation coefficient R = -1 , and highly significant at the 5% level, while the percentage absorption (%A) tends to be high for high values of mass per unit area (G) and (R) REACHES TO UNITY.
Also it has been found that , photometric measurements could be used instead of mechanical measurements in studying the structure of tested fabrics, both gave results that are strongly correlated to each other. Also    it was found that the coefficient of variation (CV%- cut and weight method) and coefficient of variation (CV%-percentage transmission), has very high correlation (R = 0.96). The results stress the appropriateness of the suggested method for nondestructive assessment of nonwoven structure. Moreover this method is directly applicable in production lines. The novel method is easy and saves much time and effort.
