Abstract: 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° C.-70° C. at a ratio Wmax±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.

Abstract: 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crimped tows from LOY, POY, or FOY filaments in a total linear density from 2 ktex to 9 ktex by filament yarns being withdrawn from creeled bobbins, folded and provided with a processing finish, then drawn or tension-uniformized and thereafter heated and stufferbox crimped.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.
