An investigation has been made of the shine, produced in wear, of wool 100 % and wool 50%/polyester 50% blended fabrics. First, the shine, produced in wear has visually been observed by a micro-scope. An appearance retention tester, for abradant of which an upholstery fabrics and other materials for desk, chairs, etc. are used, has been used to artificially reproduce the shine.
(1) The cause of shine is not only the removal of scales of wool fibers but also abrasion damages (flat spots) of wool fibers.
(2) The abradant that can produce the shine more easily are upholstery fabrics, synthetic leather of polyvinylchloride and decorative laminates used for furnitures and walls. Among decorative laminates, the laminate made from diallylphthalate resins mostly tends to produce the shine.
(3) The degree of shine evaluated visually by the sensory test correlates well with the values of contrast gloss from a goniophotometric reflection light distribution curves.
