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.
Claims30
A master batch for use in preparing a non-woven fabric in order to increase the hydrophobicity of the non-woven fabric, the master batch comprising:
- a carrier polymer;
- and
- a lipid ester comprising 10-40 wt. % of the master batch, wherein the fabric has a contact angle ranging from 100° to 125° when measured according to test method ASTM D2578.
A master batch for use in preparing a non-woven fabric in order to increase the hydrophobicity of the non-woven fabric, the master batch comprising:
- a solid, hydrophobic polymer;
- and
- a polymerized, saturated glyceride ester having a number-averaged molecular weight ranging from 500-1200.
The method for preparing a master batch for use with a fiber, the method comprising:
- providing a first polymer;
- and
- compounding a triglyceride ester with the polymer to form the master batch, the triglyceride ester comprising 10-95 wt. % of the master batch, wherein the master batch, which when shaped as a film, has a contact angle ranging from 100° to 125° when measured according to test method ASTM D2578.
