Abstract
A product includes a fabric made at least of yarns containing at least basalt fibers, the yarns or fibers being possibly at least partly provided with a sizing agent, said fabric having a weight of between about 100 g/m2 and 2000 g/m2. The product also includes at least a polyester polyurethane coating layer coating at least partly a face of the fabric, the coating having a polyester polyurethane weight of between about 5 and 100 g/m2, advantageously between 10 and 50 g/m2, preferably between 20 and 40 g/m2.
Claims40
Product comprising:
- a fabric made at least of yarns containing at least basalt fibers, said fabric having a weight comprised between 100 g/m2 and 2000 g/m2;
- at least a polyester polyurethane coating layer coating at least partly a face of the fabric, said coating layer having a polyester polyurethane weight comprised between 5 and 100 g/m2, when the coating is free or substantially free of solid particles, and a weight comprised between 35 and 65 g/m2 when the coating layer comprises more than 1% by weight solid particles.
An element comprising at least a product comprising:
- a fabric made at least of yarns containing at least basalt fibers, said fabric having a weight comprised between 100 g/m2 and 2000 g/m2;
- at least a polyester polyurethane coating layer coating at least partly a face of the fabric, said coating layer having a polyester polyurethane weight selected from the group consisting of a weight comprised between 5 g/m2 and 100 g/m2, when the coating is free or substantially free of solid particles, and a weight comprised between 35 g/m2 and 65 g/m2 when the coating layer comprises more than 1% by weight solid particles,
- in which at least a portion of the product is sewn with another portion selected from the group consisting of a portion of the product and a portion of another product of any one of the preceding claims or with another fabrics or layer or sheet.
A process for the preparation of a product comprising:
- a fabric made at least of yarns containing at least basalt fibers, said fabric having a weight comprised between 100 g/m2 and 2000 g/m2;
- at least a polyester polyurethane coating layer coating at least partly a face of the fabric, said coating layer having a polyester polyurethane weight selected from the group consisting of a weight comprises between 5 and 100 g/m2, when the coating is free or substantially free of solid particles, and a weight comprised between 35 and 65 g/m2 when the coating layer comprises more than 1% by weight solid particles,
- in which the basalt fiber containing fabric is coated at least partly with an aqueous dispersion of a polyester polyurethane, said aqueous dispersion containing at least 10% by weight polyester polyurethane.
The use of a product comprising:
- a fabric made at least of yarns containing at least basalt fibers, said fabric having a weight comprised between 100 g/m2 and 2000 g/m2;
- at least a polyester and polyurethane coating layer coating at least partly a face of the fabric, said coating layer having a polyester polyurethane weight selected from the group consisting of a weight comprised between 5 g/m2 and 100 g/m2, when the coating is free or substantially free of solid particles, and a weight comprised between 35 g/m2 and 65 g/m2 when the coating layer comprises more than 1% by weight solid particles,
- as fire protection layer.
Fire protection garment selected from the group consisting of clothes, finger, boots, mittens, gloves, cowls, helmets, said garment comprising at least a product comprising:
- a fabric made at least of yarns containing at least basalt fibers, said fabric having a weights comprised between 100 g/m2 and 2000 g/m2;
- at least a polyester polyurethane coating layer coating at least partly a face of the fabric, said coating layer having a polyester polyurethane weight selected from the group consisting of a weight comprised between 5 g/m2 and 100 g/m2, when the coating is free or substantially free of solid particles, and a weight comprised between 35 g/m2 and 65 g/m2 when the coating layer comprises more than 1% by weight solid particles.
