Definitions

  • the present invention relates to absorbent, bonded nonwoven fabrics and to methods of making the same. More particularly, the present invention is concerned with absorbent, bonded nonwoven fabrics suitable for cleaning and wiping purposes and to methods of bonding the same whereby their absorbent properties are improved over prior art bonded nonwoven fabrics.
  • the physical or geometric relationship of the two opposed binder print patterns applied to the opposite sides of the fibrous layer is such that the respective binder materials, as they penetrate inwardly from the surface of the fibrous layer either do not meet at all in the center of the fibrous layer or, if they happen to meet, do not have a common binder contact area of more than about 5 percent of the total surface area of the fibrous layer.
  • the fibrous webs which will be used to illustrate the present invention are card webs and the resulting bonded nonwoven fabrics are in the general type of Masslinn nonwoven fabrics described in patents referred to hereinafter.
  • Other types of nonwoven fabrics are, of course, applicable to the principles of the present invention.
  • Such other types of nonwoven fabrics include, for example, cross-laid card Webs; the isotropic nonwoven fabrics, as described in U.S. Patents 2,676,363 and 2,676,364; as well as the Keybak rearranged nonwoven fabrics, as described in US. Patent 2,862,251.
  • Such other fibers which may be used include natural fibers such as flax, wool, etc.; synthetic or man-made fibers including the polyamide fibers such as nylon 6/6, nylon 6/ 10, nylon 6; polyethylene tereph-thalate polyester fibers such as Dacron" and Kodel; acrylic fibers such as Orlon, Acrilan and Dyne; cellulose ester fibers such as Celanese and Arnel, vinyl fibers such as Vinyon and saran; polyolefins such as polyethylene and polypropylene; etc.
  • Such fibers are cardable and vary in length from about /2 inch up to about 2 /2 inches or more in length.
  • the weight of the fibrous web which is bonded by the techniques of the present invention will vary widely, depending primarily upon its intended use. Web weights of as low as about 200 grains per square yard may be employed, although such weights are sometimes more difficult to handle. Web weights up to about 4000 grains per square yard or even heavier may be used. Within the more commercial aspects of the present invention, however, we'b Weights of from about 500 to about 2000 grains per square yard are contemplated.
  • a durable, non-migratory binder such as viscose or regenerated cellulose
  • a durable, non-migratory binder such as viscose or regenerated cellulose
  • binders such as other cellulosic binders including hydroxyethyl cellulose, carboxymethyl cellulose, etc.
  • the emulsion type synthetic binders including acrylic binders, such as ethyl acrylate, or vinyl binders, such as polyvinyl chloride and polyvinyl acetate
  • solvent system binders such as polyvinyl chloride in toluene or xylene; etc.
  • a durable binder is selected.
  • the surface coverage of the particular print pattern selected may be varied within wide limits, depending upon many factors notably the strength, softness, durability, flexibility, or other properties desired or required in the bonded nonwoven fabric.
  • the surface coverage is also dependent upon the type of printing used to apply the binder. For example, when double opposed printing rolls are used and the nonwoven fabric is printed substantially simultaneously on both sides in a single pass, the control over the registry of the printing on both sides is accurately maintained and higher surface coverages can be tolerated. However, when the nonwoven fabric is bonded in two successive stages, one for each side of the nonwoven fabric, the control over the registry of the printing is less and consequently lower surface coverages are normally used.
  • the most important factor to be considered in the selection of a particular binder print pattern or in the use of a particular printing technique is the precentage of common binder contact which is defined herein as the percentage of the area in which the binders on each side of the nonwoven fabric are in common contact in the middle of the nonwoven fabric.
  • the common binder contact can be effectively maintained at percent of the total surface of the nonwoven fabric. Such a low percentage is highly desirable.
  • the control over the registry is reduced and consequently binder patterns and surface coverages must be so selected that the average common binder contact be maintained at less than about percent of the total surface of the bonded nonwoven fabric.
  • the average common binder contact is preferably less than about 3 percent of the total surface of the bonded nonwoven fabric.
  • the total weight of the binder which is applied to the fibrous web will vary widely, depending upon many factors such as the nature, weight and intended use of the bonded nonwoven fabric. Normally, from 2 percent to about 25 percent by weight of binder, based on the weight of the fibrous web has been found sufficient. However, for lighter fabrics, down to about 1 percent by weight is often found sufficient, whereas for heavier fabrics intended for more rugged use, up to 35 percent by weight or even more is required.

  • FIGURE 7 is a diagrammatic, fragmentary cross-section of the bonded nonwoven fabric of FIGURE 5, taken at a different portion thereof, showing the relationship and physical, geometric registry of the applied binder areas thereat.
  • FIGURES 1 through 7 are diagrammatic and that many of the lesser important details such as doctor blades, bearings, drives, belts, pulleys, fluid level controls, etc., have been omitted for the purposes of clarity.
  • FIG. 1 there is shown a fibrous web F which is being advanced between the nip of a rotatable print roll or cylinder 10 and a rotatable back-up roll 12.
  • the print cylinder 10 and the back-up roll are relatively adjustable so as to control the pressure exerted on the web passing therebetween.
  • the print cylinder 10 is partially immersed in a bath 14 of binder 16 and rotation of the print cylinder in the binder bath fills the recesses 18 therein (see FIG- URE 2) whereby the binder is printed on one side of the fibrous web as it passes through the nip of the print cylinder and the back-up roll.
  • the amount of binder printed on the fibrous web and the depth to which it penetrates depends upon many factors, such as, for example, the nature and condition of the fibrous web being bonded, the nature and condition of the binder being applied, the size and shape of the recesses in the print cylinder, etc. In the application of the present invention, these factors are so adjusted by techniques well known in the art that the binder penetrates generally about half way through the fibrous web.
  • the fibrous web After the fibrous web has passed through the nip of the print cylinder 10 and the back-up roll 12, it is guided over rotatable guide rollers 20 and 22 and is then passed through the nip of a second rotatable print roll or cylinder 22 and a second rotatable back-up roll 24.
  • the print cylinder 22 is partially immersed in a bath 26 of binder 28 and rotation of the print cylinder 22 therein results in printing of the binder on the fibrous web, although this time on the opposite side thereof, due to the reversal of the fibrous web over the guide rollers 20 and 22.
  • the application of the binder is such that it penetrates generally about half way through.
  • the recesses on the second print cylinder 22 are positioned one-half a print-unit out of registry with the recesses on the first print cylinder 10 whereby, if ideal or at least fair operating conditions prevail, the binders will be printed out of registry, such as shown in the bonded nonwoven fabric illustrated in FIGURES 5 and 6.
  • Loss of control over desired registry normally occurs when the fibrous web stretches or shrinks during its travel from the first binder printing to the second binder printing, and occurs also when the fibrous web shifts laterally during such travel.
  • Out-of-registry may, therefore, be either in the lengthwise direction, or the crosswise direction, or both.
  • the print pattern comprises spaced columns of circular binder areas, with the circular binder areas 30 being printed on the top surface of the fibrous web and the circular binder areas 32 being printed on the bottom surface of the fibrous web.
  • the binder areas penetrate generally about half way through the fibrous web but do not meet each other because they are completely out of registry and consequently there is no common binder contact area.
  • the print patterns are so selected, particularly with reference to their form and type as well as their surface coverages, that the average common binder contact area is less than about 5 percent, and preferably less than about 3 percent of the total surface of the bonded nonwoven fabric. If this principle is followed, then the outer surfaces of the fibrous web will be well bonded, lint free, and durable, Whereas the central portion will remain soft and relatively unbonded. Such creates good liquid absorbency, good liquid capacity, and low liquid strike-through properties.
  • the print cylinder 42 and the print cylinder 44 are driven in positive fashion by means of gearing (not shown) whereby the recesses 62 and 64 therein are completely out of registry, as shown more particularly in FIGURE 4.
  • gearing not shown
  • Reference to this figure will reveal that the fibrous web F is printed substantially simultaneously by the print cylinders 42 and 44 and that such printing is accurately controlled by the geared driving of the print cylinders.
  • Example I The starting fibrous mateiial is a 40-inch card web weighing about 1600 grains per square yard and comprising 50% by weight of bleached cotton and 50% by weight of viscose rayon staple fibers having a denier of about 1 /2 inches and a staple length of about 1 inches.
  • This fibrous web is bonded by being passed successively through two pairs of binder-applying rolls, as illustrated in FIGURE 1. Both pairs of rolls apply viscose to the fibrous card web; one applying the viscose to one side and the other pair of rolls applying the viscose to the other side of the fibrous card web.
  • the viscose binder is coagulated and regenerated by conventional techniques and the resulting bonded nonwoven fabric is washed and dried in standard apparatus.
  • Both surfaces of the bonded nonwoven fabric are wellbonded, lint-free, and durable; the central portion of the bonded nonwoven fabric is soft and relatively unbonded.

  • the surface coverage on each side is 12% of the surface area of the fibrous Web; the common binder contact area is 0.5% of the surface area of the bonded nonwoven web.
  • Both surfaces of the bonded nonwoven fabric are wellbonded, lint-free and durable; the central portion of the bonded nonwoven fabric is soft and relatively unbonded.
  • the bonded nonwoven fabric possesses good liquid ab sorbency, good liquid capacity, and low liquid strikethrough properties. It is useful as a lithographic wiping fabric, a cosmetic wiping fabric, and as a general wiping and cleaning cloth.
  • Example III The starting fibrous material is a 40-inch card web weighing about 600 grains per square yard and comprislng viscose rayon staple fibers having a denier of about 1 /2 and a staple length of about 1%; inches.
  • This fibrous web is bonded by being passed through the vertical-nip printing apparatus of FIGURES 3 and 4. Both rolls apply viscose substantially simultaneously to the fibrous cagd web; one roll to one side and one roll to the other si e.
  • the print patterns are wavydine print patterns which extend across the width of the fibrous web generally at about to the fiber orientation.
  • the two print patterns are similar but are staggered or spaced so that they are completely out of registry. Their geometric proportions are similar, however, and are: the width of each line is 0.025 inch and there are 4 lines per inch. The surface coverage on each side is 10%.
  • the common binder contact area is 0%.
  • the viscose binder is coagulated and regenerated by conventional techniques known to the art and the resulting bonded nonwoven fabric is washed and dried in standard apparatus.
  • Both surfaces of the bonded nonwoven fabric are wellbonded, lint-free and durable; the central portion of the bonded nonwoven fabric is soft and relatively unbonded.
  • the bonded nonwoven fabric possesses good liquid absorbency, good liquid capacity, and low liquid strikethrough properties. It is useful as a lithographic wiping fabric, a cosmetic wiping fabric, and as. a general wiping and cleaning cloth.
  • Example IV The procedures of Example HI are followed substantially as set forth therein with the exception that a different print pattern is employed.
  • the print pattern is a wavy line having a width of 0.035 inch and there are six such lines per inch.
  • the surface coverage of the binder on each side is 21%.
