Abstract
A furred thread is produced by a sequence of steps, which include impregnating a fur material with moisture. The material is stretched in a stream direction of hairs of the material and dried. The material is cut in the stream direction of the hair to produce a fur strip, which is impregnated with moisture, twisted in a manner such that its hair side appears outwardly while the strip is stretched in its longitudinal direction, and dried to produce the furred thread.
Claims2
A method for producing a furred thread, comprising the steps of:
- (a) widening a rectangular-shaped fur material in width by stretching said fur material in a direction perpendicular to a stream direction of hairs of said fur material, said fur material having been impregnated with moisture before said stretching and being dried after said stretching;
- (b) joining a plurality of said widened fur materials together by sewing them together so as to have them aligned with each other in series in said stream direction of said hairs to produce an elongated fur material;
- (c) cutting said elongated fur material in said stream direction at predetermined width intervals except at opposite upper and lower end portions thereof each of which has a predetermined length to form a plurality of longitudinal parallel cuts,
- (i) producing an annular fur material by sewing said upper and lower end portions together such that said upper and lower end portions are longitudinally offset from each other by a length equal to said width interval, and
- (ii) cutting said upper and lower end portions to produce an elongated fur strip by longitudinally extending said longitudinal parallel cuts;
- and
- (d) twisting said fur strip in a manner such that a hair side of said fur strip appears outward while said fur strip is longitudinally stretched after said fur strip has been impregnated with moisture, said twisted fur strip being then dried to produce said furred thread.
