The Impregnation of Cotton Yarns with Latex

Abstract

Abstract 1. Thin sections of yarn impregnated with rubber can be made in a simple manner according to the modified Kronacher-Lodemann method here described; and fibers, rubber, and embedding material can be clearly distinguished. 2. Impregnation of a cord with latex in which a wetting agent is dissolved results in a far lower degree of penetration by rubber than impregnation with latex following treatment of cord with a solution of the wetting agent. 3. When the proper conditions and wetting agent are selected, bicycle tire cord previously treated with a wetting agent can be completely impregnated with latex. 4. There is a definite relation between the microscopic picture indicating the degree of penetration of rubber between fibers and the results of fatigue tests.
