MIXED LINE-CONTAINING SINGLE SPUN YARN (VERSIONS) Russian patent published in 1997 - IPC

FIELD: textile industry. SUBSTANCE: invention relates to yarn with structural and natural color shape effect which meets modern design requirements for articles based on such yarn. One of yarn components (25-70%) constitutes cleaned short-fiber low-grade line with cross-section diameter 20-28 mcm and arithmetic-mean length 56-60 mm, whereas other components (10-70%) may be both short staple fibers with linear density as high as 0.2 tex and arithmetic-mean length 28-42 mm, e.g. cotton, and long staple fibers with linear density as high as 0.88 tex and arithmetic-mean length 45-90 mm, e. g. wool. Structural shape effect of such yarn is caused by presence of core and shell with different component ratios. EFFECT: reduced cost due to inexpensive raw material utilization. 6 cl, 2 dwg, 6 tbl
