A thermobondable bicomponent synthetic fibre with a length of at least about 3 mm, adapted to use in the blending of fluff pulp for the production of hygiene absorbent products, the fibre comprising an inner core component and an outer sheath component, in which the core component comprises a polyolefin or a polyester, the sheath component comprises a polyolefin, and the core component has a higher melting point than the sheath component, and a process for producing said fibre. The sheath-and-core type fibre is preferably made permanently substantially hydrophilic by incorporating a surface active agent into the sheath component. The long bicomponent fibres form a strong supporting three-dimensional matrix structure in the absorbent product upon thermobonding.
