The invention relates to a method for producing a skin/core type eccentric bicomponent fibre which is soft to touch and has improved latent crimp. An eccentric skin/core fibre which has a skin portion in relation to the cross-section of the fibre 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 - 2000 m/min. The thus obtained fibre stretches at a temperature of between 40 - 70 °C at a ratio VVmax ± 20 % and is then compressed in a crimped manner. The fibre, which is produced in such a manner, is very soft to touch and has an additional latent crimp. The fibres 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 similar.
