Abstract
The application relates to a textile composite article comprising at least one textile made of fibers/filaments, especially in the form of yarns, having a partially internal discontinuous pattern of an impregnating material which penetrates at least partially a cross section of said first textile leading to impregnated areas and non-impregnated areas in accordance with the discontinuous pattern. The non-impregnated areas are air permeable and may comprise a functional coating. Such a treated textile composite is air-permeable and water vapor permeable and has reduced water absorption and re-dry time. In one embodiment the textile composite article shows an additional enhanced flame protection.
Claims25
A textile composite article comprising:
- a first textile with an inner surface and an outer surface, said first textile comprising:
- yarns comprising multiple fibers having voids between the fibers and interstices between said yarns;
- and
- a discontinuous pattern of an impregnating material which penetrates at least partially a cross section of said first textile between the inner surface and the outer surface;
- wherein the discontinuous pattern comprises a plurality of impregnated areas separated by and completely surrounded by non-impregnated areas;
- wherein at least a portion of the voids and at least a portion of the interstices located in the impregnated areas are filled with said impregnating material;
- wherein said water absorption value of said textile composite is 70% or less according to DIN EN 29865 (1991);
- and
- wherein the non impregnated areas lead to an air permeability of the article of more than 20 l/m2/s.
A textile composite article comprising:
- a dense textile with an inner surface and an outer surface, said dense textile comprising:
- yarns comprising multiple fibers having voids between the fibers and interstices between said yarns;
- and
- a discontinuous pattern of an impregnating material which penetrates at least partially a cross section of said first textile between the inner surface and the outer surface;
- wherein the discontinuous pattern comprises a plurality of impregnated areas separated by and completely surrounded by non-impregnated areas;
- wherein at least a portion of the voids and at least a portion of the interstices located in the impregnated areas are filled with said impregnating material;
- wherein said water absorption value of said textile composite is 70% or less according to DIN EN 29865 (1991);
- wherein said interstices have an average size between and the yarns of less than 100 μm measured within 1 cm2;
- and
- wherein the non impregnated areas lead to an air permeability of the article of more than 20 l/m2/s.

- wherein at least a portion of the voids and at least a portion of the interstices located in the impregnated areas are filled with said impregnating material;
- wherein said water absorption value of said textile composite is 70% or less according to DIN EN 29865 (1991);
- wherein said impregnating material is substantially located only within said voids and said interstices;
- wherein the non impregnated areas lead to an air permeability of the article of more than 20 l/m2/s.
