Application No. 09/513,089
INTRODUCTION
Claims 5 and 6 are directed to a process of flame laminating a textile strip to a
hydrophilic polyester-polyurethane foam. The claims read as follows:
5. A continuous process for the production of a flame-laminated textile foamed material
composite comprising
(1) melting the surface of a foamed material by flaming with a gas flame burner bar,
(2) applying a textile strip material onto the melted surface of the foamed material,
and
(3) pressing the combined textile strip material and foamed material together to form a
continuous bond between the melt formed on the surface of the foamed material and the
textile strip material,
wherein the foamed material comprises a hydrophilic polyester-polyurethane foam consisting of
the reaction product of:
(a) at least one polyisocyanate,
with
(b) at least one polyester polyol containing at least two hydroxyl groups and
having an average molecular weight in the range of from more than 700 to
10,000,
(c) at least one ethoxylated polyether polyol which contains at least two
hydroxyl groups, has a molecular weight of more than 700, a functionality
of from 2 to 6, and which has a degree of ethoxylation greater than 30%
by weight, and
(d) optionally, at least one compound containing at least two active hydrogen
atoms and having an average molecular weight within the range from 32
to 700,
and
(e) catalysts, water and/or foaming agents,
and
(f) optionally, adjuvant substances and additives.
6. The process of Claim 6, wherein (3) the pressing is achieved via a pair of rotating
rollers.
