(57) A padding material of synthetic fibres having a high degree of thermal insulation
and usable advantageously in the field of clothing and furnishing comprises a base
layer (1) obtained by carding a mixture of polyester fibres which have been treated
with a mixture of adhesive resins of plastic consistency which, when polymerised,
create a very soft and elastic film and then subsequently, calendering the layer in
such a way as to reduce its initial thickness, the base layer (1) having on one or
both sides thereof a cladding layer (2) constituted by a resin, preferably polyurethane,
based on aromatic polyaters dissolved in solvent.
The cladding layer (2) itself may further have a very light finishing layer (3) applied
thereto, this finishing layer (3) being based on acrylic polymers or copolymers dissolved
in organic solvents modified with cellulosic resins such as cellulose acetyl butyrate
and may have slip agents and anti blocking substances added thereto.
