Surface modification of superdrawn polyoxymethylene fibres - Part I Interfacial miscibility in the fibre/adhesive/rubber system

Abstract

A new surface modification of superdrawn polyoxymethylene (POM) fibres, curing with resorcinol at mild temperatures, was developed to apply to rubber composites and the adhesion to the rubber matrix behaviour of modified fibres is discussed in terms of the interfacial miscibility between the fibre and adhesive surface layers. The modified fibre reached the maximum pull-out adhesion level in which a cohesive failure of the fibre occurs, resulting from the fact that the modified POM layer is spectroscopically close to the standard resorcinol-formaldehyde (RF) resin, thoroughly miscible and thermodynamically compatible with the resorcinol-formaldehyde-latex (RFL) adhesive. © 1993 Chapman & Hall.
