Claims20
A nonwoven substrate comprising:
- a layer of fibers, wherein the fibers comprise a polyolefin and an engineering thermoplastic polymer, wherein the engineering thermoplastic polymer is present in amount of about 20% or less by weight of the nonwoven substrate, and wherein the engineering thermoplastic polymer comprises polyethylene.
The nonwoven substrate wherein the layer of fibers is free of compatibilizer.
woven substrate of claim 5, wherein the plasticizer is selected from the group consisted of Citrates, Adipates, Esters, Glycerols, oils, phthalate free plasticizers, bio-based plasticizers, and mixtures thereof.
A nonwoven substrate comprising:
- a first layer of fibers, wherein the fibers comprise a polyolefin and an engineering thermoplastic polymer, wherein the engineering thermoplastic polymer is present in the range of from about 15% or less by weight of the nonwoven substrate, and a second layer of fibers free of the engineering thermoplastic polymer.
A nonwoven substrate comprising:
- a layer of fibers, wherein the fibers comprise a polyolefin, an engineering thermoplastic polymer, and a plasticizer, wherein the layer of fibers is free of compatibilizer and wherein the ratio of MD Tensile Modulus to basis weight of the nonwoven substrate is from about 0.10 to about 1.0.
