摘要： An air gun apparatus which permits stable, fine spinning and is capable of discharging fine filaments at a certain degree of dispersion and affording a non-woven fabric of uniform shape is provided. The air gun includes an air nozzle and an accelerator tube. The air nozzle has a filament inlet and outlet. The filaments are discharged from the filament outlet while being pulled by compressed air. The accelerator tube is formed at a specific diameter to length ratio and is connected to the air nozzle in the filament discharging direction. The non-woven fabric producing apparatus is provided with a guide tube and a separator nozzle, with an air flow rate regulator being disposed between the guide tube and the separator nozzle. The air flow rate regulator has an exhaust port for exhausting to the exterior a portion of the compressed air which is used for carrying the filaments.

摘要： Nonwoven fabrics formed, in spun-bonding process, of crimped bi-component composite filaments composed of (A) a first component composed of (a) 3 to 40% by weight of a propylene/ethylene random copolymer having a melting point, determined from DSC main peaks of 110.degree. to 150.degree. C. and a melt flow rate [ASTM D-1238 (L)] of not more than 15 g/10 minutes and (b) 97 to 60% by weight of polyethylene having a melt flow rate [ASTM-D-1238 (E)] of at least 15 g/10 minutes, and (B) a second component comprising crystalline polypropylene having a melt flow rate [ASTM D-1238 (L)] of at least 10 g/10 min. as a main component, have a soft feel and are suitable for use as, e.g., disposable bed sheets and liners for diapers.

摘要： An object of the present invention is to provide a dispersing device which can disperse filaments uniformly and widely on a moving collector surface by suppressing the turbulence of an air flow as a carrier medium for the filaments to thereby reduce the disturbance of the filaments.The dispersing device (1) of the present invention is formed as a dispersing pipe consisting of a pair of dispersing plates (2) vertically extending so as to be opposed to each other and a pair of side plates (3) connecting the dispersing plates. The dispersing pipe has an upper end formed with a filaments inlet and a lower end formed with an oblong filaments outlet (5) surrounded by the dispersing plates and the side plates. The dispersing pipe has a shape such that a space t between the dispersing plates is decreased with an increase in distance z from the filaments inlet toward the filaments outlet (5), and that a space w between the side plates is increased with the increase in the distance z. According to the dispersing device of the present invention, the turbulence of the carrier air flow is reduced to thereby uniformly and widely disperse the filaments on the moving collector surface (14). Accordingly, a web having a good appearance with less nonuniformity and less yarn bundles can be obtained.
