The changes in the optical property of textile surfaces subjected to the repetitive extension, cause the angular distribution of reflected light to vary, influencing the appearances of textiles.
In correspondence with the variation in the distribution of the reflected light, the changes of optical property are roughly classified into the following three patterns:
Type 1: The surface conditions are hardly changed.
Type 2: The textile surfaces are flattened.
Type 3: The concavity and convexity of textile surfaces are intensified.
When the change is intensive, type 2 accompanies luster and type 3 sometimes reduces it greatly.
