The invention relates to a polymer fibre with improved dispersibility, a method for producing said fibre and the use of said fibre. The polymer fibre according to the invention comprises at least one synthetic polymer and 0.1 and 20 wt. % of a silicone. The polymer forming the fibre forms a solid dispersion medium at room temperature (25&#xb0; C.) for the silicone present in solid form also at room temperature (25&#xb0; C.) which forms the more disperse phase. The polymer fibre according to the invention possesses an improved dispersibility and is therefore suitable for producing aqueous suspensions which are used, for example, in the formation of textile fabrics, e.g. nonwovens.

A process is described for producing thin crimped tows from LOY, POY, or FOY filaments in a total linear density from 2 ktex to 9 ktex by filament yarns being withdrawn from creeled bobbins, folded and provided with a processing finish, then drawn or tension-uniformized and thereafter heated and stufferbox crimped. The process can be carried out in-line with numerous further processing operations. The tows are particularly useful for producing textile hygiene articles such as diapers, sanitary napkins, inserts and incontinence guards and the like.

A method for producing a skin/core type eccentric biocomponent fiber which is soft to touch and has improved latent crimp. An eccentric skin/core fiber which has a skin portion in relation to the cross-section of the fiber of 35%-70% is produced by melt spinning polyester as a core component and polyethylene as a skin component at a spinning speed of between 600 m/min-2000 m/min. The thus-obtained fiber stretches at a temperature of between 40&#xb0; C.-70&#xb0; C. at a ratio W&#xb1;20% and is then compressed in a crimped manner. The fiber, which is produced in such a manner, is very soft to touch and has an additional latent crimp. The fibrer are particularly suitable for producing hygiene products such as hygienic non-woven fabrics, and all kinds of hygienic textile flat items for producing nappies, bandages, inserts, cotton buds, and the like.
