1. A method of forming a tack cloth comprising a nonwoven web material, the method comprising:
compounding a first polymer with a second polymer and a tackifier, wherein the first polymer comprises an olefin homopolymer and the second polymer comprises an olefin-based plastomer, to form a first polymer blend, wherein the second polymer is an olefin-based plastomer having a glass transition temperature of less than about 25° C., and the tackifier comprises a hydrocarbon resin, a polyterpene resin, a terpene-phenol resin, or a combination thereof;
forming fibers from the first polymer blend, wherein the fibers comprise the first polymer present in an amount of 45 wt % based on the total weight of the nonwoven web material, the second polymer present in an amount of 45 wt % based on the total weight of the nonwoven web material, and a tackifier present in an amount of 5-10 wt % based on the total weight of the nonwoven web material, wherein the second polymer is present in an amount equal to or greater than the amount of the first polymer based on the total weight of the nonwoven web material, wherein the difference between the amount of the second polymer and the amount of the first polymer is in a range from 0 wt % to 5 wt %;
collecting the fibers onto a foraminous surface to form the nonwoven web material; and
imparting a texture onto the nonwoven web material with a textured forming wire, wherein the nonwoven web material comprises a meltblown or spunbond nonwoven web material, wherein the nonwoven web material is textured to form a three-dimensional topography, wherein the nonwoven web material has a dust holding capacity of from about 10 grams/m2 to about 130 grams/m2, and wherein the amount of residue present on a surface wiped with the nonwoven web material ranges from about 0 grams/m2 to about 0.02 grams/m2, wherein the tack cloth is a wipe or a glove.
