A granular material for use in the treating of textile materials, comprising (i) a silicone material having at least one nitrogen containing substituent, (ii) an aluminosilicate carrier and (iii) a binder, preferably in conjunction with a surface active material. Also described is a process for preparing such granular materials, which comprises forming a water-in-oil emulsion of component (i) in conjunction with component (iii) by dispersing and agitating said components in water, followed by depositing said emulsion onto a free flowing powder form of component (ii), for example by spraying, and removing sufficient water from the product to obtain a free flowing granular material. The granules are useful in a process of treating textile materials in an aqueous medium, particularly where the textile material is denim. Preferably the granular material is added into the finishing steps of denim such as the desizing, the fading or the softening steps and helps with avoiding backstaining.
A process for finishing denim materials comprising preparing granular material comprising (i) a silicone material having at least one nitrogen containing substituent, (ii) at least 40% by weight of an aluminosilicate carrier, and (iii) a binder which is a film forming polymer and is a polyacrylic acid,
A process of finishing denim materials which comprises the use of a granular material by adding the granular material to an aqueous medium in which the denim materials are being finished, wherein the granular material comprises (i) a silicone material having at least one nitrogen containing substituent, (ii) at least 40% by weight of an aluminosilicate carrier, and (iii) a binder which is a film forming polymer and is a polyacrylic acid.
A process of minimising the backstaining of denim during a fading process by using in the fading process a granular material comprising (i) a silicone material having at least one nitrogen containing substituent, (ii) at least 40% by weight of an aluminosilicate carrier, and (iii) a binder which is a film forming polymer and is a polyacrylic acid.
