Abstract
A household appliance liner includes a first polymeric capping layer and a polymeric base layer. The first polymeric capping layer includes a first pigment additive. The polymeric base layer is coupled to the first polymeric capping layer. The polymeric base layer includes one or more polymers, a second pigment additive, and a natural fiber. The natural fiber can be present at a concentration of at least 50% by weight of the polymeric base layer. Methods of producing the household appliance liner are also disclosed.
Claims18
A household appliance liner, comprising:
- a first polymeric capping layer comprising a first pigment additive;
- and
- a polymeric base layer coupled to the first polymeric capping layer, the polymeric base layer comprising:
- one or more polymers;
- a second pigment additive;
- and
- a natural cellulose-like fiber, the natural cellulose-like fiber being present at a concentration of at least 50% by weight of the polymeric base layer, wherein the natural cellulose-like fiber is at least one of, a wood pulp, and a cotton-lint fiber, and wherein the natural cellulose-like fiber is bleached and pre-colored with the second pigment additive prior to mixing the natural cellulose-like fiber with the one or more polymers.
A household appliance liner, comprising:
- a first polymeric capping layer formed from:
- a first pigment additive, wherein the first pigment additive is present at a concentration of about 5% to about 30% by weight of the first polymeric capping layer;
- and
- a first polymeric capping layer precursor at a concentration of about 70% to about 95% by weight of the first polymeric capping layer;
- and
- a polymeric base layer coupled to the first polymeric capping layer, the polymeric base layer comprising:
- one or more polymers;
- a second pigment additive, wherein the second pigment additive is present in the polymeric base layer at a concentration of about 1% to about 30% by weight of the polymeric base layer;
- and
- a natural cellulose-like fiber, the natural cellulose-like fiber being present at a concentration of at least 50% by weight of the polymeric base layer, wherein the natural cellulose-like fiber is a cotton-lint fiber.
