Flexible material, its production method and uses

A composition for a coating of a textile substrate selected from the group consisting of knitted, woven, nonwoven fabrics, paper, and combinations thereof, the composition comprising:

• 50% to 90% (pbinder/ppaste) of a suitable polymer binder of synthetic or natural origin or a combination thereof;
• 5% to 50% (presidue/ppaste) of residue particles with a particle size of less than 1 mm,
• wherein the residue is of vegetable origin selected from the group consisting of:
• forest residues, cereal residues, agricultural residues, horticultural residues, silvicultural residues, paper residues, vegetable by-products excluding cork, and mixtures thereof;
• and
• wherein the composition comprises a viscosity between 20-100 dPa·s at 20° C.

A method for obtaining a flexible material, the method comprising:

• selecting residue particles with a particle size of less than 1 mm, wherein the residue particles are of vegetable origin selected from the group consisting of forest residues, cereal residues, agricultural residues, horticultural residues, silvicultural residues, paper residues, vegetable by-products excluding cork, and mixtures thereof;
• mixing at least 5% of the residue particles (presidue/pcoating) with a polymer binder in order to obtain a paste having a viscosity between 20-100 dPa·s at 20° C.;
• optionally, incorporating air into the paste, this including a foamer, so as to obtain a coating foam;
• applying, by knife coating or rotary screen, at least one layer of the paste or the coating foam obtained onto a textile substrate or a cellulose-based substrate selected from the group consisting of:
• knitted, woven, nonwoven fabrics, paper and combinations thereof;
• and
• optionally drying, thermosetting and/or calendering the coating foam or paste, the thermosetting and calendering being carried out in different orders.
