Title:
METHOD FOR MANUFACTURING BLACK COTTON-LIKE FIBERS
Document Type and Number:
WIPO Patent Application WO/2023/116211
Kind Code:
A1
Abstract:
A method for manufacturing a black cotton-like fibers, which adopts a DTY elasticity enhancing process. Carbon black-containing polyester POY and FDY fibers (1) sequentially pass through a first filament guide (2), a godet roller (3), a tensioner (4), a first filament supply roller (5), a pre-interlacer (6), a second filament supply roller (7), a first deformation hot box (8), a cooling plate (9), a false twister (10), a third filament supply roller (11), a middle interlacer (12), a shaping hot box (13), a shaping filament supply roller (14) and an oiler (15), and are wound to obtain black cotton-like cotton fibers. The first filament guide (2) is a filament guide wheel. In the movement process, the tow contacts the groove bottom of the first filament guide (2) to drive the first filament guide (2) to rotate. The tensioner (4) is a magnetic tensioner. In the movement process, the tow contacts the groove bottom of the filament guide wheel provided with the tensioner (4), and the inferior angle formed before and after the tow contacts the groove bottom is between 140 and 160 degrees. The tensile force of the tensioner (4) is set to 7 to 10 cN. The linear speed ratio of the first filament supply roller (5) to the second first filament supply roller (7) is 1.03 to 1.04. The method can reduce the abrasion of the first filament guide (2), and improve the interlacing degree of the tow, and is free from loose filaments.
