Abstract
A method for making a disposable absorbent article is provided. The method comprises the steps of providing a first nonwoven comprising synthetic fibers comprising a 14C/C ratio of about 1.0×10−14 or greater, providing a second nonwoven comprising synthetic fibers comprising a comprising a 14C/C ratio of about 1.0×10−14 or greater, converting the second nonwoven into a topsheet so that the topsheet comprises a Liquid Strike Through value of less than 4 seconds, and combining the first nonwoven and the topsheet with other absorbent article components to form a disposable absorbent article.
Claims26
A method for making a polyolefin for use in a disposable absorbent article, the method comprising the steps of:
- (a) providing a first monomer derived from a renewable resource;
- (b) providing a second monomer derived from petrochemicals;
- (c) polymerizing the first monomer and the second monomer to form a polyolefin comprising the first monomer and the second monomer;
- and
- (d) extruding the polyolefin to form a film, fibers, or filaments for use in one of more components of a disposable absorbent article.
A method for making a polyolefin for use in a disposable absorbent article, the method comprising the steps of:
- (a) providing a first monomer derived from a renewable resource, wherein the first monomer derived from the renewable resource is at least partially derived from sugar cane, sugar beets, starch, cellulose, sugars, glycerol, biomass, or combinations thereof;
- (b) providing a second monomer derived from petrochemicals;
- (c) polymerizing the first monomer and the second monomer to form a polyolefin comprising the first monomer and the second monomer;
- and
- (d) extruding the polyolefin to form a film, fibers, or filaments for use in one of more components of a disposable absorbent article.
A method for making a polyolefin for use in a disposable absorbent article, the method comprising the steps of:
- (a) providing a mixture of a first monomer derived from a renewable resource and a second monomer derived from petrochemicals;
- (b) polymerizing the mixture to form a polyolefin comprising the first monomer and the second monomer;
- and
- (c) extruding the polyolefin to form a film, fibers, or filaments for use in one of more components of a disposable absorbent article.
