Abstract:
A method to form yarn via film fiberizing spinning belongs to a textile technical field. A film cutting device is arranged behind each drafting system on a ring frame, whose cut resistance apron and cutting roller engage with each other to form a cutting zone to cut and fiberize the film to get belt-like multi-filaments. Then the multi-filament formed passes through the first, second and third drafting zones in sequence for drawing, in such a manner that the multi-filament molecular orientation and crystallization are improved. After being drafted, the multi-filaments are twisted into yarn by ring spinning, which provides a novel high-efficient and short-processing way of producing yarns of nano-micro fibers using films instead of conventional nano-spun fibers such as electro- and centrifugal spun fibers, thereby breaking restriction of “low bulk and low-speed production of nano-spun fibers” and integrating the film industry with the textile industry.

Claim (Index 1):
A method to form yarn via film fiberizing spinning, comprising steps of: arranging a film cutting device behind each drafting system on a ring frame, wherein the drafting system comprises a rear roller ( 8 ), a rear rubber roller ( 7 ), a middle roller ( 11 ), a middle rubber roller ( 10 ), a front roller ( 14 ), and a front rubber roller ( 13 ); the film cutting device comprises a bearing roller ( 16 ), an unwinding roller ( 4 ) and a cutting roller ( 5 ); a cut resistance apron ( 3 ) is wrapped onto the unwinding roller ( 4 ); loop blades, which are arranged in parallel, are located on the cutting roller ( 5 ) circumference; the cut resistance apron ( 3 ) corresponds to cutter edges of the loop blades located on the cutting roller ( 5 ); a cutting zone is formed between the cut resistance apron ( 3 ) and the cutting roller ( 5 ); centers of the cutting zone, the rear rubber roller ( 7 ), the middle rubber roller ( 10 ) and the front rubber roller ( 13 ) are in a same plane; the rear rubber roller ( 7 ) and the rear roller ( 8 ) of the drafting system engage with each other to form a rear roller nip; a first drafting zone is formed between the cutting zone and the rear roller nip; a filament guider ( 6 ) is provided in the first drafting zone; an extended line of an input end of a guiding tunnel of the filament guider ( 6 ) is tangent with the cutting zone; an extended line of an output end of the guiding tunnel of the filament guider ( 6 ) is tangent with the rear rubber roller ( 7 ) at the rear roller nip; the middle roller ( 11 ) and the middle rubber roller ( 10 ) of the drafting system engage with each other to form a middle roller nip; a second drafting zone is formed between the rear roller nip and the middle roller nip; a first heater ( 9 ) is provided in the second drafting zone; a heating groove of the first heater ( 9 ) is parallel to an axis of the rear roller nip and an axis of the middle roller nip; the front roller ( 14 ) and the front rubber roller ( 13 ) engage with each other to form a front roller nip; a third drafting zone is formed between the middle roller nip and the front roller nip; a second heater ( 12 ) is provided in the second drafting zone; a heating groove of the second heater ( 12 ) is parallel to the axis of the middle roller nip and an axis of the front roller nip;\n during spinning, placing a film roll ( 1 ) between the bearing roller ( 16 ) and the unwinding roller ( 4 ), wherein films unwound from the film roll ( 1 ) enter the cutting zone formed between the cut resistance apron ( 3 ) and the unwinding roller ( 4 ); the film cutting device cuts and fiberizes the films to form belt-like multi-filament which are evenly paved before entering the first drafting zone, wherein the multi-filaments get a primary drawing; after the primary drawing, the multi-filaments outputting from the rear roller nip via the filament guider ( 6 ) enter the second drafting zone, wherein the multi-filaments heated in the heating groove of the first heater ( 9 ) get a secondary drawing; after the secondary drawing the multi-filaments outputting from the middle roller nip enter the third drafting zone, wherein the multi-filaments heated in the heating groove of the second heater ( 12 ) get a main drawing; after the main drawing, the multi-filaments outputting from the front roller nip are converged and twisted to form a yarn, subsequently the yarn passes through a pig-tail guider ( 15 ) of yarn, a ring and a traveler successively, and is finally winding onto a yarn bobbin.
