Abstract (en)
[origin: EP0238422A1] 1. A non-woven material, formed by the association of leather fibres with fibres capable of ensuring chemical bonding at the commencement of drying, and fibres capable of ensuring thermal bonding at the end of drying, the fibres of the said material being finally bonded at points by the intermediary of the fibres that ensure chemical bonding and those ensuring thermal bonding, characterized in that the chemical bonding is ensured by polyvinyl alcohol fibres, and the thermal bonding is ensured by two-constituent fibres comprising a reinforcing core and an envelope, the melting temperature of which core is greater than the softening temperature of the said envelope.
