Abstract
The invention pertains to the field of technical textiles, and more particularly to the field of textiles used as a carrier, in particular as a carrier for active compounds or compounds to be activated. The invention thus relates to a glass, quartz, or metal pile fabric, as well as to a catalytic fabric. The invention also relates to a method for manufacturing said fabric.
Claims12
A photocatalytic fabric forming a contact surface for treatment of a surrounding medium, wherein the medium is air, said photocatalytic fabric comprising a pile fabric consisting of:
- a weft and at least one ground warp of twisted glass yarns, of size ranging from 5 to 2000 tex;
- and
- a pile warp of pile height between 2 and 8 mm, the yarns of which are twisted yarns made of glass, of size ranging from 5 to 2000 tex;
- wherein the photocatalytic pile fabric comprises at least one photocatalyst,
- wherein the pile fabric is a carrier for the photocatalyst and wherein the photocatalyst is deposited on the pile fabric;
- wherein the photocatalyst is deposited by spraying the photocatalyst onto the pile fabric, or by dipping the pile fabric into a solution of photocatalyst;
- and
- wherein the pile density of the pile fabric is between 60 and 120 pile yarns per cm2.
A method for manufacturing a photocatalytic pile fabric, said photocatalytic pile fabric forming a contact surface for treatment of a surrounding medium, wherein the medium is air, said method comprising manufacturing a pile fabric comprising the following:
- at least one warping to prepare at least one ground warp of twisted glass yarns, of size ranging from 5 to 2000 tex;
- warping to prepare a pile warp having a pile height between 2 and 8 mm in glass and a size ranging from 5 to 2000 tex;
- weaving the ground and pile warps with a weft of twisted glass yarns of size ranging from 5 to 2000 tex;
- and
- cutting the pile warp yarns;
- so that the manufactured pile fabric consists of a weft and at least one ground warp of twisted glass yarns, of size ranging from 5 to 2000 tex;
- and of a pile warp of pile height between 2 and 8 mm, the yarns of which are twisted yarns made of glass, of size ranging from 5 to 2000 tex;
- and
- said method further comprising a step of depositing a photocatalyst on the pile fabric for forming the photocatalytic pile fabric for treatment of a surrounding medium, wherein the medium is air,
- wherein the photocatalyst is deposited by spraying the photocatalyst onto the pile fabric, or by dipping the pile fabric into a solution of photocatalyst, and
- wherein the pile density of the pile fabric is between 60 and 120 pile yarns per cm2.
