Method to produce a pile textile product and a textile product resulting from the same
View Patent ↗A method for manufacturing a textile product includes the steps of providing an intermediate product formed by a backing having a front surface and a back surface, and yarns applied into the backing, the yarns extending from the front surface of the backing material, feeding the intermediate product along a body having a heated surface, the back surface being pressed against the heated surface, to at least partly melt the yarns present in the intermediate product to form the textile product, wherein the part of the back surface that is pressed against the heated surface has a relative speed with respect to the heated surface, and a device enabling applications of this method and to a floor covering incorporating such a textile product connected to a dimensionally stable carrier sheet using thermo reversible covalent interactions.
1. A method for manufacturing a carpet comprising the steps of:
providing an intermediate product comprising a backing including a thermoplastic material and having a front surface and a back surface, and yarns applied into the backing, the yarns extending from the front surface of the backing material,
feeding the intermediate product along a body having a heated surface, the back surface being pressed against the heated surface, to at least partly melt the yarns present in the intermediate product to form the carpet such that the thermoplastic material of the backing co-melts with the yarns,
providing a relative speed of the part of the back surface that is pressed against the heated surface with respect to the heated surface.
2. A method according to claim 1 , wherein the heated surface is an edge of a blade.
3. A method according to claim 2 , wherein the step of feeding includes a step of feeding the intermediate product between the blade and a rotating drum facing the blade.
4. A method according to claim 2 , further including a step of vibrating the blade when pressed against the back surface.
5. A method according to claim 2 , further comprising a step of thermally connecting the blade to a non-flat carrying element.
6. A method according to claim 1 , further comprising a step of preheating the back surface before being pressed against the heated surface of the body.
7. A method according to claim 6 , wherein the step of preheating includes a step of preheating the back surface by pressing a heated preheat surface against the back surface, the preheat surface being one of:
a preheat drum and
a preheat blade.
8. A method according to claim 1 , wherein the yarns extend through the backing, and further comprising a step of melting at least a part of the yarns that extends out of the back surface.
9. A method according to claim 8 , further comprising a step of at least partially melting a part of the yarns applied into the backing.
10. A method according to claim 1 , Wherein the backing is a non woven fibrous material.
