D02G1/00 - CPC Classification

Classification description:

Producing crimped or curled fibres, filaments, yarns, or threads, giving them latent characteristics

Sub-classes:

D02G1/002 » {by knitting, weaving or tufting, fixing and then unravelling} 8
D02G1/004 » {by heating fibres, filaments, yarns or threads so as to create a temperature gradient across their diameter, thereby imparting them latent asymmetrical shrinkage properties} 22
D02G1/006 » {by impinging the yarn against an uneven surface and thereby deforming it} 4
D02G1/008 » {with provision for imparting irregular effects to the yarn} 7
D02G1/02 » by twisting, fixing the twist and backtwisting, i.e. by imparting false twist 34
D02G1/10 » using knife edges, e.g. heated knife edges, for edge crimping 3
D02G1/12 » using stuffer boxes 80
D02G1/14 » using grooved rollers or gear-wheel-type members 14
D02G1/16 » using jets or streams of turbulent gases, e.g. air, steam 27
D02G1/18 » by combining fibres, filaments, or yarns, having different shrinkage characteristics 29
D02G1/20 » Combinations of two or more of the above-mentioned operations or devices; After-treatments for fixing crimp or curl 38
