In preceding papers[1, 2] the distribution curves for the specular reflection light, i.e., goniophotometric curves, were computed to simulate fabrics by using the following two fabric models. (1) The first fabric model
(1) consists of fine elliptic cylinders arranged side by side on the surface of an elliptic column. A parallel luminous flux perpendicular to the axes of the above elliptic cylinders is assumed to project to the surface of the fabric model.
(2) The second model[2] is assumed to consist of a number of very short elliptic columns stacked side by side with all the columns sharing a common major axis length of 2 but columns varying in short axis length. Incident light flux is assumed to be parallel to the major axes of the columns.
In the preceding papers[1, 2], the goniophotometric curves for the two fabric models were computed assuming a refractive index of 1.5. However, the refractive index of actual filaments range from 1.3 to 1.8. In the present paper in view of above calculations were made of the goniophotometric curves of above fabric models considering a range of refractive index from 1.3 to 1.8.
The present computer simulation yielded the following results.
(1) Fabrics made from filaments having smaller refractive index look deeper in color than fabric from filaments having comparatively larger refractive index when a parallel luminous flux is projected to the fabrics. The reason for this is because a small refractive index tends to make a larger percentage of incident light enter the fiber to make the observed color deep.
(2) Fabrics more rugged in surface look deeper in color than fabrics of less rugged surface because rugged surface lets more light into the individual filaments.

The data obtained from a survey of the fabric handle preferences of panels of judges drawn from the textile and clothing industries of Japan, Australia, India, New Zealand and the United States of America are compared with data provided from objective mechanical measurements.
The model used takes into account the fact that judges may differ in their assessment in non-random ways, for example, some judges may prefer thicker fabrics, and gives a picture of how objective measurements may perform not only to explain, but also to predict how individual judges perform.
Although it is demonstrated that a substantial amount of individual sudjective handle assessment can be explained by mechanical test parameters, predictions of handle assessment by Australian judges compared with their actual assessments were generally poorer when based on objective data, rather than subjective data. The implication of this is that the set of mechanical measurements used in the analysis did not contain all the necessary information to predict fabric handle preference.

In the prvious report, [1] the fiber content has been enhanced by the effective use of fiber forming characters and by applying not only the centrifugal force but also roll pressure and balloon pressure.
This report analyzes the formation of high fiber content. The analysis has been made on the basis of an anisotropic model[2] with several assumptions. Influences on the fiber content have been studied of the centrifugal force, roll pressure and balloon pressure force[3]-[8] caused by the fiber lamination. In addition, the results of an experiment in the previous report is compared with this analysis.
