SYNTHETIC LEATHER AND METHOD FOR MANUFACTURING SYNTHETIC LEATHER

1 . A multilayer synthetic leather, at least comprising

a textile arrangement; and

a polyurethane based foam;

wherein

the polyurethane-based foam is partially fixed to the textile arrangement using a first fixing layer such that the first fixing layer has fixing areas formed by a fixing agent and free areas free from the fixing agent in the same plane.

2 . The synthetic leather according to claim 1 , wherein the first fixing layer is applied in a punctiform manner, in the form of rhombusses or in the form of bars.

3 . The synthetic leather according to claim 1 , wherein the first fixing layer is applied in an amount of ≥2 to ≤50 g/m 2 , in particular ≥10 g/m 2 to ≤20 g/m.

4 . The synthetic leather according to claim 1 , wherein the textile arrangement consists of a textile layer.

5 . The synthetic leather according to claim 1 , wherein the textile arrangement comprises a textile layer and a water-impermeable membrane, the water-impermeable membrane being partially fixed to the textile layer using a second fixing layer in such a way that the second fixing layer comprises fixing areas formed by a fixing agent and free areas free from the fixing agent in the same plane.

6 . The synthetic leather according to claim 1 , wherein further a top layer is provided on the polyurethane-based foam.

7 . The synthetic leather according to claim 6 , wherein the top layer is at least in part formed from a particularly aliphatic polyester-polyurethane dispersion.

8 . The synthetic leather according to claim 1 , wherein at least one of the first fixing layer and the second fixing layer is formed at least partially from a hot-melt adhesive or from a particularly aliphatic polyester-polyurethane dispersion.

9 . The synthetic leather according to claim 1 , wherein the polyurethane based foam comprises a silicone.

10 . The synthetic leather according to claim 1 , wherein the polyurethane-based foam has a solid content of ≥40% by volume, preferably in a range from ≥40% by volume to ≤70% by volume.

11 . A method of manufacturing a multi-layer synthetic leather according to claim 1 , comprising the steps of:

a) Providing a support;

b) Optionally, applying a top layer to the support;

c) Applying a polyurethane-based foam to the support or, if a top layer is present on the support, to the top layer;

d) Partially applying a first fixing layer to the polyurethane-based foam or to a textile arrangement to form fixing areas formed by a fixing agent and free areas free from the fixing agent in the same plane;

e) Applying the textile arrangement to the polyurethane-based foam; and

f) Removing the support.

12 . A method of manufacturing a multi-layer synthetic leather according to claim 1 , comprising the steps of:

g) Providing a textile arrangement;

h) Providing a polyurethane based foam;

i) Partially applying a first fixing layer to the polyurethane-based foam or to the textile arrangement to form fixing areas formed by a fixing agent and free areas free from the fixing agent in the same plane;

j) Assembling the polyurethane-based foam and the textile arrangement; and

k) Optionally, applying a top layer to the polyurethane-based foam.

13 . The method according to claim 11 , wherein the first fixing layer is applied in process step d) or in process step i) by using a screen printing process.

14 . The method according to claim 11 , wherein the support is a grained backing paper.

15 . The method according to claim 11 , wherein the method comprises the further step of: I) hydrophobizing at least one of the top layer and the foam.

16 . The method according to claim 12 , wherein the first fixing layer is applied in process step d) or in process step i) by using a screen printing process.

17 . The method according to claim 12 , wherein the method comprises the further step of: I) hydrophobizing at least one of the top layer and the foam.
