A size composition is described which is capable of increasing the adherence, and particularly the adherence to rubber, of multifilament yarns having a base of polyester, a base of polymers of high modulus of elasticity, or a base of thermostable polymers, wherein said size composition contains tris(epoxypropoxy 2,3)3-propionyl 1,3,5-hexahydro-s-triazine as preadhering agent, preferably present in an amount between 1 and 30% based on the weight of the size composition. The treated yarn is thereafter bonded to a desired substrate, such as rubber. |
