Abstract
A soil repellency aqueous dispersion for treating various fibers, yarns, and textiles is disclosed. The dispersion provides superior soil resistance when compared to known fluorochemical and silicone fiber treatments. The dispersion comprises clay nanoparticle components and fluorochemicals that can be applied to the fibers, yarns, and textiles using known methods.
Claims20
A fiber comprising a surface treatment comprising at least one clay nanoparticle component and a fluorochemical, wherein said fluorochemical is selected from the group consisting of fluorochemical allophanates, fluorochemical polyacrylates, fluorochemical urethanes, fluorochemical carbodiimides, and fluorochemical quanidines and wherein said fluorochemical has less than or equal to six fluorinated carbons per fluorinated side-chain, and wherein said at least one clay nanoparticle component is selected from the group consisting of montmorillonite, hectorite, saponite, nontronite, beidellite and combinations thereof.
The fiber of claim& 1, wherein said at least one clay nanoparticle component is synthetic.
An article comprising:
- a fiber comprising at least one clay nanoparticle component, a fluorochemical and a component selected from the group consisting of silicones, optical brighteners, antibacterial components, anti-oxidant stabilizers, coloring agents, light stabilizers, UV absorbers, base dyes, and acid dyes, and wherein said at least one clay nanoparticle component is selected from the group consisting of montmorillonite, hectorite, saponite, nontronite, beidellite and combinations thereof.
