Definitions

  • the invention relates to a nonwoven fabric having a valuable combination of properties that makes the fabric particularly useful as a wiping cloth.
  • Wiping surfaces of aqueous liquids is an activity practiced by virtually everyone, whether at home, at play; or at work.
  • properties desired of a cloth used for wiping aqueous liquids are the following:
  • This invention is directed to a nonwoven fabric that has these properties.
  • the fabric of the invention comprises a substantially isotropic web of lightly entangled rayon staple fibers containing a small amount of adhesive binder substantially uniformly distributed throughout said web, the amount of said binder being sufficient to resist wet collapse of said web, wherein the fabric has an excellent balance of wiping properties, abrasion resistance, resistance to staining, and softness or handle characteristics.
  • a random laid web 10 of rayon staple fibers is passed onto a liquid pervious support member, such as an endless woven belt 12.
  • the belt 12 carries the web of fibers 10 under a series of high pressure, fine, essentially columnar jets of water 14.
  • the high pressure water is supplied from a manifold 16.
  • the jets 14 are arranged in rows disposed transversely across the path of travel of the belt 12.
  • there is a vacuum means 15 pulling a vacuum of e.g., up to 5 to 10 inches of mercury (16.93 to 33.86 kPa), beneath the belt 12, with a vacuum slot positioned directly under each row of jets 14.
  • the fibers in the web 10 are rearranged and entangled by the jets 14 as the liquid from the jets 14 passes through the fibrous web 10 and then through the belt 12.
  • the fabric 18 is carried by the belt 12 over a vacuum dewatering station 20, and then proceeds to a series of drying cans 22.
  • Evans in U.S. Patent No. 3,485,706, describes a process and apparatus for rearranging/entangling fibrous webs by carrying such webs on a woven belt under a series of high pressure, fine, columnar jets of liquid. Apparatus of the general type disclosed by Evans can be used in the process of this invention, although typically the degree of entanglement contemplated by this invention is much less than that generally preferred by Evans.
  • the degree of fiber entanglement contemplated by this invention is preferably that obtained by the use of jet pressures of from about 200 to about 700 psi (1.38 to 4.83 MPa), and up to about 20 to 25 rows of orifices, with the orifices being spaced such that there are about 30 to 50 per liner inch (2.54 cm).
  • the orifices are usually about 0.005 to 0.007 inch (0.13 to 0.18 mm) in diameter.
  • the web is usually positioned about 1/2 to 1-1/2 inches (1.27 to 3.81 cm) below the orifices. With web speeds of from about 8 to about 100 yards (7.32 to 91.44 m) per minute, fibrous webs of from about 1/2 to about 5 ounces per square yards (152.6 to 1526 g/m 2 ) are conveniently processed.
  • the dried web 23 proceeds to a bonding station 25 wherein an aqueous resin binder composition is applied uniformly to the dried web 23, as by a padder (shown schematically in Fig. 1).
  • the padder includes an adjustable upper rotatable top roll 24 mounted on a rotatable shaft 26, in light pressure contact, or stopped to provide a 1 or 2 mil (25.4 to 50.8 um) gap between the rolls, with a lower pick-up roll 28 mounted on a rotatable shaft 30.
  • the lower pick-up roll 28 is partially immersed in a bath 36 of aqueous resin binder composition 38.
  • the pick-up roll 28 has a smooth rubber surface and the top roll 24 has a steel surface, which may be smooth or engraved.
  • the pick-up roll 28 picks up resin binder composition 38 and transfers it to the web 23 at the nip between the two rolls 24, 28.
  • the binder-containing web 39 is then subjected to elevated temperature, as by passing around a set of drying cans 40, to dry and/or cure the resin binder, and the web 41 containing the dried and/or cured binder is then collected, as on a conventional wind-up 42.
  • the fibers used in the invention are rayon staple fibers, i.e., rayon fibers having lengths of at least one-half inch up to about three inches (1.27 to 7.62 cm). Some of the rayon fibers can be replaced with other fibers such as polyester staple fibers. However, the fibers used are predominantly rayon, e.g., at least about 70 weight per cent rayon and preferably at least 80 weight per cent rayon.
  • the resin binder composition can be the conventional aqueous latex compositions, such as acrylic latexes, polyvinyl acetate latexes, ethylene-vinyl acetate latexes, carboxylated styrene-butadiene rubber latexes, or the like.
  • Acrylic latex binders are preferred for maximum resistance to staining.
  • One important difference compared with conventional procedures is that the resin binder composition will usually be quite dilute, e.g., from about 1/2 to about 5 weight per cent solids, when applied by padding or dipping onto a dry web. Slightly higher solids may be needed when applying to a wet web.
  • the amount of resin binder employed is a small amount, e.g., up to about 10 weight per cent, based on weight of fibers plus binder.
  • the minimum amount is that amount that is sufficient to impart wet collapse resistance to the fabric.
  • the exact amount used will depend, to a degree, on factors such as weight of fabric, presence or absence of polyester, polypropylene, or other water-resistant fibers (when polyester fibers are used, the amount of binder can be slightly less), exact end use intended, and the like.
  • the amount of binder used will usually be within the range of from about 0.8 to about 10 weight per cent, based on fibers plus binder.
  • the fabrics of the invention are relatively isotropic, that is, their tensile strengths are not more than about three, and preferably about two, times their tensile strengths in the cross direction.
  • Such isotropicity is obtained by employing a random laid web as the starting web 10.
  • the starting web can be produced by air laying by known procedures, as by using a "Rando Webber" or a dual rotor as disclosed in U.S. Patent Nos. 3,963,392; 3,768,118; 3,740,797; 3,772,730; and 3,895,089.
  • the fabrics of the invention are relatively bulky, which enhances their absorbent capacities. Their bulk densities are usually within the range of from about 0.07 to about 0.13 grams/cc.
  • Avtex SN1913, 1.5 denier, 1-1/8 inch (2.86 cm) staple rayon was processed through an opener/blender and fed to a random air laying unit, which deposited a 800 ⁇ 15% grains per square yard (62 g/m z ⁇ 15%) web onto a forming belt woven of 0.0157 inch (0.4 mm) diameter polyester monofilaments. It is a dual layer fabric having two superimposed layers each having 42 warp monofilaments per inch (2.54 cm), and 32 shute monofilaments per inch (2.54 cm) woven through the warp monofilaments in the following repeating pattern: under two, between the two, over two, between the two, etc. It is available commercially from Appleton Wire Division of Albany International as Type 5710 Duotex polyester belt.
  • the web was passed under a water weir to wet the fiber, and was then carried at a speed of 23 yards (21 m) per minute under 12 orifice strips, each of which contained a row of holes, 50 holes per inch (127 per cm), of 0.005 inch (0.13 mm) diameter.
  • Water, at 120°F (50°C) was jetted through the holes in the orifice strips at 100 psi (0.689 MPa) for the first three strips and 600 psi (4.14 MPa) for the remainder.
  • the web was dewatered by passing over a vacuum slot, and then passed over two stacks of steam cans to dry it.
  • the stacks of steam cans were operated at 90 psi and 85 psi (621 and 586 kPa) steam pressure, respectively.
  • the dried web was then run through a padder similar to the one shown in the Fig. 1, and the following binder formulation was impregnated in the web:
  • the finished fabric had a binder content of about 7.5 weight per cent, based on weight of fibers plus binder, and a grain weight of about 875 grains per square yards (67.8 g/m 2 ).
  • Example 2 The processing conditions under the water jets were the same as in Example 1. After dewatering, the entangled web was passed over two stacks of steam cans operated at 40 psi (274 kPa).
  • the wet pick-up of the binder composition is 200 weight per cent, based on weight of fibers.
  • the web containing the binder composition was then passed over two stacks of drying cans, the first stack of which was operated at increasing pressures of 20 to 60 psi (138 to 414 kPa), and the second at 90 psi (621 kPa).
  • the finished fabric had a binder content of about 1 weight per cent, based on weight of fibers plus binder, and a grain weight of about 875 grains per square yard (67.8 g/m 2 ).
  • This Example 2 illustrates one preferred fabric of the invention.
  • This fabric is shown in Figs. 2 and 3. It is characterized by two series of bands 50 and 52 that are substantially perpendicular to each other. As seen most clearly in Fig. 3, each band in both series contains segments in which the individual fibers are all substantially parallel to each other, which segments alternate with regions 54 in which the fibers are randomly entangled. These regions 54 occur where an individual band of one series 50 intersects an individual band of the other series 52. Also, at regularly spaced intervals between the individual bands of both of said series of bands 50 and 52, there are openings or holes 56 in the fabric.
  • This preferred fabric of the invention is produced by a procedure analogous to that described in Example 1 the significant feature being the forming belt.
  • the forming belt is a single layer, plain weave belt woven of monofilaments.
  • Table III below displays representative physical properties of the fabrics of Examples 1 and 2.
  • the fabrics of this invention have an excellent combination of properties that make them useful as wiping cloths.
  • Table III illustrate the excellent combination of softness, absorbent capacity, abrasion resistance, and durability (launderability) exhibited by these fabrics.
  • Simulated use testing has demonstrated that the fabrics resist staining by foods such as catsup, mustard, coffee, and greasy materials, so that when the fabrics are used to wipe up such materials, the fabrics rinse clean with little or no residual discoloration. This makes the fabrics excellent for use as wipes in places such as kitchens, restaurants, fast food establishments, and ice cream counters, wherein it is advantageous for the fabrics to remain unstained after repeated uses and rinses.
  • the absorbent capacity, take-up rate, and the amount of residue left after wiping (or, more precisely, blotting), of the fabrics of Examples 1 and 2 were determined using a gravimetric absorbency tester ("GAT").
  • GAT gravimetric absorbency tester
  • the GAT is an apparatus for determining the weight and rate of liquid flowing to or from a test site.
  • the apparatus comprises, in combination:
  • the liquid used was water, and the test surface used for determining absorbent capacity and take-up or absorbency rate was a flat plate with a point source of liquid connected to the vessel.
  • the test surface used was a flat glass plate having a 6 centimeter in diameter circular test area circumscribed by a groove in the surface of the glass.
  • a quantity of water equal to 50 per cent of the calculated absorbent capacity of the specimen to be tested was placed in the test area.
  • the specimen (10 centimeters in diameter), mounted on a flat, circular specimen holder 8 centimeters in diameter was brought into contact with the test area containing the water.
  • a contact pressure of about 3.5 grams/cm 2 was used, and the contact time was about 30 seconds.
  • the test specimen was then removed, and the weight of the residue was determined.
  • Example 2 The conditions under the water jets were similar to that of Example 1, except that only 6 instead of 9 strips at 600 psi (4.14 MPa) were used.
  • the web was passed over two stacks of steam cans operated at 20 and 40 psi (138 and 274 kPa), respectively.
  • the dried web was then run through a bonding station that differed from the padder shown in Fig. 1 in the following respects:
  • the fabric was then dried by passing over two stacks of steam cans operated at 40 psi (274 kPa).
  • the finished fabric had a binder content of about 1.5 weight per cent, based on weight of fibers plus binder, with the binder being distributed substantially uniformly throughout the webs.
  • the two fabrics had very similar physical properties. Representative physical properties are shown below in Table VIII:
  • Figs. 4 and 5 show the fabric of Example 3 and Figs. 6 and 7 show the fabric of Example 4. As can best be seen in Figs. 5 and 7, which were taken with transmitted light, the fabrics have the same basic morphology as the fabric of Example 2, differing only in scale.
