Abstract
Reinforcing fabrics or cords, particularly those made from adhesive activated (AA) polyester yarn, or non-adhesive activated (non-AA) polyester yarn, or aramid yarn, maybe coated in a first of two dips in a two-step (double-dip) process, or more preferably in a single-step (single-dip) process, with an adhesive dispersion comprising a solid finely divided reversibly blocked polyisocyanate (RBP), having a majority of its primary particles smaller than 1 micron in average diameter, when the RBP is held in suspension as a substantially homogeneous dispersion with the aid of a hydrocarbyl disperser. The RBP is so held with less agitation than is required to produce a vortex in the dispersion. There is no 'flaking' on the fabric after it is dried at a temperature higher than 250.degree. F. for less than about 3 minutes, and heat-set at a temperature above that at which the RBP is unblocked. Vulcanized rubber goods reinforced with the coated and cured fabric or cord, characteristically fail in cohesive rubber failure.
