Abstract

820,279. Artificial fur. RONA, L. May 16, 1956, No. 15186/56. Class 42 (2). Animal hairs are formed into a layer upon a flat surface, the hairs being at right angles to the surface, and the ends of the hairs adjacent the surface are formed into a felted layer so as to form an artificial fur. Wool clipped from the sheep, wherein the outer parts of the hair are entangled, may be placed on an endless belt provided with convergent side guides which pack the hairs more closely together, the hairs being maintained in a position at right angles to the belt with the assistance of a vacuum below the belt and/or compressed air above. The lower ends of the hairs may be treated with a hot alkaline detergent solution, heated, and acted upon with a reciprocating brush in a series of steps, whch may be repeated, causing felting. The free ends may be carbonized by treatment with sulphuric acid and heat and then washed, and the felted ends may be treated with formaldehyde and coated with rubber latex or a synthetic resin. The finished artificial fur may be passed through a carding machine and cutter. A layer of horizontally disposed fibres may be incorporated in the felted layer or a similar layer of fibres may be incorporated between two plastic coatings applied to the felt. As an alternative method, both ends of the hairs may be felted and the product cut along the centre to provide two artificial furs. Wool which has been cleaned may be treated, the outer ends of the hairs being held by adhesive bands of textile material, by a fine metal screen provided with carding hooks or by a sprayed-on adhesive. Pieces of otherwise useless skins may be matched and placed upon a perforated stainless steel plate and the skins removed by chemical or bacteriological methods to produce an artificial fur.
