description Methods for improving the tear strength in non-woven chopped strand mats during the manufacturing process of the mats are provided. In particular, the tear strength of the mat can be improved as the mat is being formed in response to current manufacturing conditions by the addition of a water soluble polyol, such as polyvinyl alcohol, or a cationic dispersant to the binder seal pit. Alternatively, a cationic dispersant may be added to the white water chest to improve the tear strength of the chopped strand mat. The addition of polyvinyl alcohol or a cationic dispersant to the binder seal pit results in an immediate or nearly immediate improvement of the tear strength of the chopped strand mat. Both the polyvinyl alcohol and the cationic dispersant can be utilized to improve the tear strength of a chopped strand mat regardless of the type of binder or components in the white water.
