Tacky Finish and Textile Materials and Articles Treated Therewith

摘要

This invention relates to tacky finishes and to the textile materials and articles treated with the tacky finishes. The tacky finishes provide improved processing features for end-use articles that contain such finishes. The tacky finish may be combined with other adhesion promotion finishes in the treatment of textile materials. The textile materials and articles may be used as rubber reinforcing materials, such as automotive tire cap ply, single end tire cord, carcass reinforcement and side wall reinforcement. End-use articles that contain the treated textile materials include rubber-containing materials such as automobile tires, belts, and hoses. This invention also relates to the methods for manufacturing the treated textile materials and articles.

1. A coated textile material comprising:
(1) a textile substrate; (2) disposed on at least one surface of the textile substrate, at first layer of a composition (a) comprising a resorcinol-formaldehyde-latex; and (3) disposed on the first layer, a second layer of a tacky finish (b) comprised of
(i) at least one tacky resin selected from phenol-containing resins, aromatic resins, hydrocarbon resins, terpene resins, indene resins, coumarone resins, rosin-based resins, and mixtures thereof;(ii) at least one unvulcanized rubber selected from polybutadiene, polyisoprene, synthetic trans-rich polyisoprene or cis-rich polyisoprene, natural rubber, poly(styrene-co-butadiene), poly(acrylonitrile-cobutadiene), chloroprene, hydrogenated styrene-butadiene rubber, hydrogenated nitrile-butadiene rubber, butyl rubber, polyisobutylene copolymer rubber, halo-butyl rubber, and mixtures thereof, and(iii) at least one adhesion promoter selected from formaldehyde-resorcinol condensate and/or resin, formaldehyde-phenol condensate, novolac resins, resole resins, multifunctional epoxy resin, novolac modified epoxy resin, isocyanate compounds, blocked isocyanate resin or compounds, halogenated resorcinol-formaldehyde resin, phenolic resins, halogenated phenolic resins, melamine-formaldehyde resins, vinyl pyridine rubber latex, methylene donors, organofunctional silanes, and mixtures thereof.
