Claim 6
Independent Claim
97 words
A method of treating polyolefin fibers comprising the steps of introducing within the fibers (1) a polyamino compound containing at least one dye-receptive site selected from the class of compounds having the formulas: H2NC3H6(OC3H6)nNH2 and H2NC2H4(OC2H4)nNH2 where n has a value of 2 to 20, and (2) a polyepoxy compound capable of polymerizing to form a copolymer with said polyamino compound selected from the group consisting of polyglycidyl ethers of glycols and polyols, bisglycidyl ethers of polyhydric phenols, vinyl cyclohexene dioxide, and butadiene diepoxide; and heating the fibers to copoLymerize and insolubilize the monomers within the fibers.
