Abstract
A high tenacity fiber for reinforcing plastic composites, the fiber being selected from the group consisting of polyester, aliphatic polyamide, and combinations thereof. The fiber is treated with a composition comprising an aqueous solution of carboxyl-terminated, oil-free alkyd resins based on an aliphatic glycol or glycols or a glycol ether or ethers containing 2 to 12 carbon or carbon plus ether oxygens with a combination of aromatic di-or trifunctional carboxylic acids, said resins having a degree of esterification below the gel point of the resins to enhance stiffness of the fiber for cutting.
