| 摘要 |
The present invention consists of a thickener particularly useful for thickening print compositions containing inks, dyes and/or pigments for application to textile. In particular, the thickening composition is comprised of at least three components, namely, vegetable oil, polyacrylic acid polymer/copolymer, an alkali material, and optional components such as an antioxidant. The vegetable oil can contain up to 50% by weight mineral oil. The polyacrylic acid can be a polymer or copolymer. The optional antioxidant is typically an organic compound and is employed to retard or prevent deterioration of the vegetable oil. Lastly, the alkali material is employed to help gel the polyacrylic acid. The thickener composition contains about 25 to about 75% by weight vegetable oil with or without mineral oil, from about 20 to 70% by weight polyacrylic acid or acrylic copolymer, from about 3 to 25% by weight alkali material, and optionally from about 0.5 to 3% by weight antioxidant wherein the total comprises 100%. The composition of the present invention is particularly useful in compositions having printing inks, dyes or pigments used in textile applications. It is contemplated that approximately 1 to 7% by weight of the thickener composition is employed in the ink, dye or pigment composition.
