Patent ID: 7927530

Claim:
Method for manufacturing an eccentric bicomponent fibre composite of the core/skin type with a soft feel and having improved latent crimping, comprising: manufacturing an eccentric core/skin fibre composite, with a skin portion comprising 35% to 70% of the cross section of the fibre composite, by melt spinning polyethylene terephthalate as the core component and polyethylene as the skin component, at a spinning speed of 600 m/min to 2,000 m/min, drawing the fibre thus obtained at a temperature of 40° C. to 70° C. and at a total drawing ratio VV max in a range of 1.4 to 2.4 in a single drawing stage, then stuff-crimping the drawn fibre, VV max being the drawing ratio at which the number of arcs per cm reaches a maximum.
