Coated fibrous based substrates

摘要

A method of treating a fibrous substrate comprising introducing inorganic receptor sites within the fibrous substrate and coating the treated substrate with a coating formulation comprising a compound containing epoxy and alkoxysilane groups. Preferred inorganic receptor sites are metallic salt compounds, especially aluminium sulfate, aluminium chloride, aluminium triformate, or potassium aluminium sulfate (alum). The coating formulation may comprise polyurethane, acrylic, epoxy, or silicone based dispersions. The compound containing epoxy and alkoxysilane groups is preferably a glycidoxy alkoxy silane, especially 3-glycidoxypropyltriethoxysilane. A natural or synthetic fibrous substrate may be treated wholly or partially according to the treatment method. A wholly or partially treated natural or synthetic fibrous substrate may wholly or partially make a glove, an article of footwear, an article of clothing, leathergoods, or an article of seating may be upholstered wholly or partially of natural or synthetic fibrous substrate treated wholly or partially by the treatment method.
