Synopsis

The adhesion characteristics of Nylon-6 cords to rubber matrix, using Resorcinol Formaldehyde Latex (RFL) solution, were evaluated at various conditions. The heat-setting studies of RFLdipped cords in the temperature range of 180-21OoC showed a loss in tensile properties. However, a minimum in the lass was obsenred when a pretension load was given to the cords. Percent shrinkage of RFGdipped cords increased with the increase in temperature of heat setting. Adhesion behavior of Nylon-6 cords to rubber matrix showed some improvement under relaxed conditions in the entire temperature range studied. With the application of suitable tension to cord, adhesion behavior can be made constant. This has been attributed to the higher extent of shrinkage of cords under relaxed conditions providing greater cord surface area. This in turn, leads to increased cord to rubber matrix.
