  • Nonwoven webs and processes for making them are known in the art.
  • Processes for making nonwoven webs may comprise three steps: fiber laying, precursor web formation, and fiber bonding.
  • the fiber laying step may be comprised of the spunlaying, meltblowing, carding, airlaying, wetlaying and combinations thereof, of the fibers comprising the web onto a forming surface.
  • the step of precursor web formation may prevent the fibers comprising the web from coming apart during the bonding step.

  • the bonding step may then impart strength to the finished web.
  • the bonding step may be comprised of subjecting the fibers comprising the web to hydroentanglement (HET), cold calendering, hot calendering, air thru bonding, chemical bonding, needle punching, and combinations thereof.
  • HET hydroentanglement
  • precursor web formation may add to the cost of making nonwoven webs by requiring the separate step of pre-bonding the fibers comprising the web.
  • the pre- bonding steps may affect the properties of the nonwoven web. For example, while pre-bonding may increase the durability of a nonwoven web, it may also increase its stiffness and, in turn, decrease its softness to the touch. Examples of processes requiring precursor web formation and the nonwoven materials made thereby may be found in: U.S. Patents 5,023,130, 5,573,841,
  • Processes known in the art for making nonwoven webs may produce nonwoven webs having sufficient strength in the machine direction; however, they may not produce nonwoven webs that also have sufficient strength in the cross-direction. When such nonwoven webs are pulled in the cross-direction, they may stretch and ultimately tear.

Additionally, the liquid composition used to premoisten the nonwoven webs of the present invention exhibit the property of surface tension. I. Absorptive capacity
  • the following method is suitable to measure the absorptive capacity of any nonwoven web (when dry or wet) or finished wipe (when dry or wet).

  • Cylinder/Piston Apparatus A suitable piston apparatus is manufactured by Machinetek Corporation of Fairfield, Ohio U.S.A.
  • the apparatus consists of a piston/cylinder apparatus and a sorption apparatus.
  • the piston/cylinder apparatus used for this measurement has three parts.
  • the bottom of the cylinder is faced with a No. 400 mesh stainless-steel screen cloth that is biaxially stretched to tautness prior to attachment.
  • the piston consists of a Teflon ® or Kel-F ® "cup" and a stainless steel weight.
  • the cup is machined to fit into the cylinder within tight tolerances.
  • the cylindrical stainless steel weight is machined to fit snugly within the cup and is fitted with a handle on the top.

  • a second stainless steel weight with the combined weight of the cup and weight being 596 g (0.30 psi) is also provided.
  • the samples can be tested without use of the piston/cup/cylinder assembly and new disk weights may be machined to obtain desired confining pressures.
  • an in use pressure range of 0.07 to 0.10 psi is acceptable.
  • representative confining pressures should be determined on a case by case basis.
  • the components of the apparatus are sized such that the flow rate of the solution through the apparatus under a 10 cm hydrostatic head is at least 0.01 (g/cm ⁇ ) per sec, where the flow rate is normalized by the area of the fritted disc in the apparatus.
  • Factors particularly impacting system permeability may include the permeability of the fritted disc and the inner diameters of glass tubing and stopcocks.
  • the apparatus' reservoir is positioned on an analytical balance that is at least accurate to ⁇ 0.01 g with a drift of less than 0.1 g/hr.
  • the balance is preferably interfaced to a computer with software that can: (i) monitor balance weight change at pre-set time intervals from the initiation of the absorptive capacity test and (ii) be set to auto-initiate on a weight change of 0.01 - 0.05 g, depending on balance sensitivity.
  • the tube entering the reservoir should not contact either the bottom of the reservoir or its cover.
  • the volume of fluid in the reservoir should be sufficient (e.g. at least 40 mL) such that, during the procedure, air is not drawn into the tube.
  • the fluid level in the reservoir should be about 2 mm below the top surface of the fritted disc. This can be confirmed by placing a small drop of fluid on the disc and gravimetrically monitoring its slow flow back into the reservoir. This level should not change significantly when the piston/cylinder apparatus is positioned on the frit.
  • the reservoir should have a sufficiently large diameter (e.g., about 15 cm) so that withdrawal of fluid during the procedure (e.g., about 40 mL) results in only a small change in the fluid height (e.g., less than 3 mm).
  • the quantity of fluid that drains from the frit in this procedure (called the frit correction weight) is measured by conducting the procedure (see below) for a time period of 15 minutes without the piston/cylinder apparatus. Essentially all of the fluid drained from the frit via this procedure is very quickly reabsorbed by the frit when the procedure is initiated. Thus, it is necessary to subtract this frit-correction weight from weights of fluid removed from the reservoir during the procedure. The frit correction is stable so this procedure may only be performed every 10 - 15 measurements. Procedure Before weighing the substrate, wipe the inner surface of the cylinder and outer surface of the cup with isopropanol (if using the cylinder assembly). Allow to air dry. If using the cylinder assembly, now insert the substrate into the piston cup and add to the cylinder.

  • Absorptive Capacity (t) IW f ftFffl - W r (f) - Wf c l

  • Wf c is the frit correction weight in grams (measured separately)
  • W ⁇ g ⁇ g. dry basis ⁇ s me dry weight in grams of the substrate Absorptive Capacity is typically reported for times of 3 minutes after initiation. Additionally, if an electronic data collection system is being used, a maximum absorptive capacity can be obtained by substituting the maximum weight in grams from the reservoir, W r (max) for W r (t). This resolves the maximum absorptive capacity of the material:

  • the wipes of the present invention may also have an absorptive capacity of greater than about 6 grams of liquid per wipe.
