  • Patent number: 12291611
    Abstract: Solid-state branching and/or crosslinking of aliphatic polyamide or polyester articles is achieved using a topical approach. A surface of the article is coated with a composition that includes a polyene and a free radical initiator. The article and applied coating are then heated to induce branching and/or crosslinking in the polyamide or polyester. This is performed below the crystalline melting temperature of the polyamide or polyester, or in the case of a fabric, below the melting temperature of the fibers in the fabric. Fabrics treated in this manner exhibit reduced or even no dripping in vertical flame tests.

  • Patent number: 11377789
    Abstract: A non-aqueous fabric dyeing method using a non-aqueous dyeing composition is described. The dyeing composition is a fluid at room temperature; contains no more than 5% water, no more than 5% VOCs and no more than 2.5% by weight vinyl monomers. The dye composition includes an organic dye that is solid at temperatures up to 130° C. and which sublimes or boils at 130 to 220° C., and further includes a carrier that is a liquid in the temperature range of 130 to 220° C.

  • Patent number: 10919647
    Abstract: Fabrics are treated with a hydrophobic treatment that includes at least one hydrophobic monomer and a crosslinker. The treatment is low in volatile organic compounds and water. It is a liquid at 22° C. or a suspension having a phase that is liquid at 22° C. The monomer and crosslinker are cured in a free radical polymerization to form a hydrophobic coating on a fibrous substrate. The curing is performed by removing interstitial air from the fabric and then curing the fabric in a low oxygen environment without allowing it contact with oxygen or air from the time the interstitial air is removed until conversion of monomers reaches at least 50%.
