The present invention relates to a device and to a method for producing a texturized filament or yarn, wherein at least one filament is guided into a draw device, is guided there by a pair of intake rollers towards at least two pairs of drafting system rollers and drawn by the same, downstream of which is disposed a texturizing device with a cooling drum. Downstream the texturizing device with the cooling drum is disposed at least one cooled drafting system roller, by which the filament, respectively the yarn is cooled to a temperature of 0° C. to 50° C.

A method and a device for opening a fiber bundle, capable of performing a fluctuating operation, at a high speed, of pushing a part of a conveyed fiber bundle by a contact member into a stress state and then separating the contact member from the fiber bundle so as to temporarily relax the fiber bundle, and also capable of reducing damage to the fiber bundle. The device for opening a fiber bundle includes a conveying portion 5 for pulling out a fiber bundle Tm from a yarn feeding body 11 and conveying it in a fiber length direction, a fiber-opening processing portion 3 for opening the fiber bundle by moving a fiber in a width direction while bending the fiber by letting a fluid pass through the conveyed fiber bundle Tm, and a fluctuation imparting portion 4 for rotating a contact member 42 in a direction inclined with respect to a conveyance direction while bringing it into contact with the conveyed fiber bundle Tm and pushing a part of the fiber bundle Tm into a stress state, and then separating the contact member 42 from the fiber bundle Tm in the stress state so as to temporarily bring the fiber bundle Tm into a relaxed state.

A method of spreading fibres, the method comprises providing a continuous fibre bundle having an initial width W.sub.a and causing the fibre bundle to run, in a running direction, through tensioning means and past or through fluid flow means, the tensioning means intermittently varying the tension in the fibre bundle and the fluid flow means producing a fluid flow through the fibre bundle as the tension varies in the fibre bundle, whereby the width of the fibre bundle increases to a spread width W.sub.b. Apparatus (1) is also disclosed, which apparatus (1) comprises a tensioning means (3) to intermittently vary the tension in the fibre bundle (2) and a fluid flow means (4) for producing a flow of fluid through the bundle (2).

A polymeric material fiber includes a polymeric material which is a homopolymer of caprolactone or a copolymer of at least 90% by weight of caprolactone and one or more additional monomers. An implantable mesh includes this fiber alone or combined with one or more additional fiber materials. Methods for treating patients involve implanting the fiber material, for example incorporated in a mesh.

A method for spreading a tow of textile non-braided filaments, preferably chemical or inorganic fibres comprises providing a tow of textile non-braided filaments extending along its own main direction and having a section transverse to the main direction with a predetermined thickness and a predetermined width, feeding the tow along a travel path and spreading the tow in order to increase its width and reduce its thickness, defining a spread tow. The step of spreading the tow includes immersing the tow in a bath and generating in the bath a sequence of transverse waves crossing the tow transversely to the main direction in order to separate and place the individual filaments side by side, thereby spreading the tow, wherein the tow entering the bath and/or the spread tow extracted from the bath is/are unsized.
