Abstract
The present invention relates to a hydrophobic additive for use with fabric, fiber, and film. One aspect of the present invention comprises a master batch composition for use in preparing a non-woven fabric in order to increase the hydrophobicity of the non-woven fabric. In one embodiment, the master batch composition includes a polymer and a lipid ester. The lipid ester comprises from 10 wt. % to 40 wt. % of the master batch. The fabric, when including the master batch composition, has a contact angle ranging from 100° to 125° when measured according to test method ASTM D2578.
