Abstract
The invention relates to bleached cotton fibers and to absorbing materials for disposable articles. Its object is a process for shortening bleached cotton fibers consisting in (a) moving a fiber pad (1) between a trough-plate (2) and a feed roller (5) exerting a pressure between 0.3 and 0.6 MPa on the fiber pad, (b) pulling the fiber pad (1) beyond the trough-plate (2) bevelled at (9) so as to cut the long fibers constituting the fiber pad, (c) reconstituting the sheet. This process makes it possible to obtain fibers which can be used directly in diaper-making machines. The disposable articles so produced offer remarkable absorbing properties.
Claims9
A process for shortening textile fibers comprising
- (a) continuously moving a pad of fibers between a trough-plate and a feed roller provided with a rounded roughness which rotates in the feed direction of the fiber pad and compresses said pad, the pressure exerted by said feed roller on said fiber pad being controlled so as to exceed 0.25 MPa;
- (b) pulling the fiber pad beyond said roughness plate by means of a drum provided with a cutting roughness rotating in the same direction as the feed roller but at a tangential speed at least 50 times that of the speed of the feed roller;
- and
- (c) tearing at least a part of the textile fibers having a length exceeding 10 mm of said fiber pad, said tearing being obtained by engaging said fibers with means located in a vertical space between the top of said trough-plate and the cutting roughness of said drum to cause said tearing of said textile fibers with a length in excess of 10 mm.
