<p>A process for treating a yarn and/or a fabric to form fine inorganic particulate material in the intra-yarn pores and/or on the surface of the fibres constituting the yarn or fabric, which would substantially maintain fabric reflectance after repeated wash/wear cycles without affecting the desired characteristics of air permeability. The inorganic particles are preferably formed by reacting in an aqueous medium a first reagent selected from mineral and organic acids and a second reagent selected from alkali or alkaline earth metal salts with inorganic anions. The invention also relates to a treatment product composition directed to provide instant inorganic deposits in the yarn or fibre surface.</p> |
