Abstract
A nonwoven web material of polymeric fibers having at least one internal surfactant and at least one topical surfactant. The internal surfactant is an organosilicon compound. The topical surfactant is at least one of an ethoxylated hydrogenated fatty oil, a monosaccharide, a monosaccharide derivative, a polysaccharide, and a polysaccharide derivative. The nonwoven web material treated with internal and external surfactants has improved durability and processability over conventional materials treated with only internal or topical surfactants.
Claims39
A nonwoven web material comprising:
- polymeric fibers comprising at least one internal surfactant and at least one topical surfactant, said at least one internal surfactant comprising an organosilicon compound and said at least one topical surfactant comprising a mixture including an ethoxylated hydrogenated fatty oil and a compound selected from the group consisting of a monosaccharide, a monosaccharide derivative, a polysaccharide and a polysaccharide derivative.
A method for producing a nonwoven web material comprising the steps of:
- adding an internal surfactant comprising an organosilicon compound to a polyolefin resin, forming an organosilicon/polyolefin resin;
- processing said organosilicon/polyolefin resin to form a nonwoven web material;
- and
- applying at least one topical surfactant to said nonwoven web material said at least one topical surfactant comprising a mixture including an ethoxylated hydrogenated fatty oil and a compound selected from the group consisting of a monosaccharide, a monosaccharide derivative, a polysaccharide and a polysaccharide derivative.
A dual treatment method for improving durability and processability of nonwoven materials comprising:
- adding an internal additive comprising at least one organosilicon compound surfactant to a polyolefin resin prior to formation of said nonwoven material;
- and
- adding a topical surfactant comprising a mixture including an ethoxylated hydrogenated fatty oil and a compound selected from the group consisting of a monosaccharide, a monosaccharide derivative, a polysaccharide and a polysaccharide derivative, to a fluid intake side of said nonwoven materials.
A limited use or disposable article comprising:
- a nonwoven material comprising polymeric fibers comprising at least one internal surfactant and at least one topical surfactant, said at least one internal surfactant comprising an organosilicon polymer and said at least one topical surfactant comprising a mixture including an ethoxylated hydrogenated fatty oil and a compound selected from the group consisting of a monosaccharide, a monosaccharide derivative, a polysaccharide and a polysaccharide derivative.
A nonwoven web material comprising:
- polymeric fibers formed from a mixture of a polyolefin resin and at least one internal surfactant and having at least one topical surfactant comprising a mixture including an ethoxylated hydrogenated fatty oil and a compound selected from the group consisting of a monosaccharide, a monosaccharide derivative, a polysaccharide and a polysaccharide derivative, said at least one internal surfactant having a capability to bloom without heating of said polymeric fibers and provide said polymeric fibers with instantaneous wettability.
A method for producing a nonwoven web material comprising the steps of:
- adding an internal surfactant to a polyolefin resin, forming a surfactant/polyolefin resin mixture;
- processing said surfactant/polyolefin resin mixture to form a nonwoven web material, said internal surfactant blooming within said nonwoven web material without application of additional heat to said nonwoven web material, thereby providing said nonwoven web material with substantially instantaneous wettability;
- and
- applying at least one topical surfactant to said nonwoven web material, said at least one topical surfactant comprising a mixture including an ethoxylated hydrogenated fatty oil and a compound selected from the group consisting of a monosaccharide, a monosaccharide derivative, a polysaccharide and a polysaccharide derivative.
