Document Type and Number:
WIPO Patent Application WO/2007/072703
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a ply cord for polyester tire caps which has a high modulus and is significantly improved in adhesiveness to rubbers and fatigue resistance; and a process for producing the cord. [MEANS FOR SOLVING PROBLEMS] The process for producing a ply cord for polyester tire caps is characterized in that adhesiveness to rubbers is imparted to a fibrous polyester material by treating the material with a first treating bath comprising (A) a polyepoxide compound, (B) a blocked polyisocyanate compound, and (C) a rubber latex, the proportions by weight on a solid basis of the ingredients satisfying (A)/[(A)+(B)] of 0.05-0.9 and (C)/[(A)+(B)] of 0.5-15, subsequently treating it with a second treating bath comprising a resorcinol-formalin-rubber latex, and then heating the resultant material under a normalizing tension regulated to 0.2 cN/dtex or higher.
