Abstract:
A hydroentangled nonwoven sheet material produced by a process including: 0) optionally providing a polymer web on a carrier; a) providing an aqueous suspension containing short fibres and a surfactant; h) depositing the aqueous suspension on the carrier; c) removing aqueous residue of the aqueous suspension deposited in step h) to form a fibrous web; b′) depositing aqueous suspension on a surface of the fibrous web formed in step c); c′) removing aqueous residue of the aqueous suspension deposited in step b′) to form a combined fibrous web; d) hydroentangling the combined fibrous web; and optionally e) drying the hydroentangled web, and/or f) further processing and finalising the dried, hydroentangled web the web to produce the nonwoven end material. The hydroentangled non-woven sheet material obtainable by this process has a low degree of surface irregularity and contains low residues of surfactants.

Claim (Index 1):
A process of producing a hydroentangled nonwoven sheet material of at least one of natural and/or manmade fibres, comprising:\n a) providing an aqueous suspension containing short fibres and a surfactant; b) depositing the aqueous suspension on a carrier; c) removing aqueous residue of the aqueous suspension deposited in step b) to form a fibrous web; b\u2032) depositing aqueous suspension containing short fibres and surfactant on the surface of the fibrous web formed in step c) and at the side not facing the carrier; c\u2032) removing aqueous residue of the aqueous suspension deposited in step b\u2032) to form a combined fibrous web; and subsequently d) hydroentangling the combined fibrous web.
