  • ABSTRACT A strong, absorbent, abrasion-resistant, bonded nonwoven fabric comprising a fibrous layer of: (1) from 0% by weight to about 75% by weight of textile length staple fibers; and (2) from 100% by weight to about 25% by weight of short fibers having a length less than the textile length staple fibers, the fibrous layer being bonded by: (1); primary, intermittently-spaced print pattern binder sites extending substantially from one surface of the fibrous layer to the other surface of the fibrous layer; and (2) secondary, intermittentlyspaced, print pattern binder sites positioned predominantly on the surface of the fibrous layer and located thereon between the intermittently-spaced binder sites of the primary print pattern binder.
  • the present invention relates to strong, absorbent, abrasion-resistant, bonded nonwoven fabrics and to methods 'of making the same. More particularly, the present invention is concerned with strong, absorbent, abrasion-resistant, bonded nonwoven fabrics suitable for cleaning and wiping purposes and to methods of bonding the same whereby the strength, absorbency, and abrasion-resistant properties are improved over those of prior art bonded nonwoven fabrics. Even more particularly, the present invention is concerned with improved, strong, absorbent, and abrasion-resistant wiping materials for absorbing and holding oleaginous substances such as greases, oils and fats, and to novel methods of making the same.
  • Bonded nonwoven fabrics have been used hitherto in many uses, such as, for example, wiping and cleaning cloths, and have been found to be generally satisfactory and commercially acceptable in industry.
  • a strong, absorbent, abrasionresistant, bonded nonwoven fabric comprising a fibrous layer of: l from by weight to about 75% by weight of textile length staple fibers; and (2) from 100% by weight to about 25% by weight of short fibers having a length less than the textile length staple fibers, the fibrous layer being bonded by: (1) primary, inerrnittently-spaced print pattern binder sites extending substantially from one surface of the fibrous layer to the other surface of the fibrous layer and; (2) secondary intermittently-spaced print pattern binder sites positioned predominantly on the surface of the fibrous layer and located thereon between the intermittently-spaced binder sites of the primary print pattern binder.
  • FIG. 1 is a simplified, diagrammatic, schematic flow chart illustrating one method embodiment of the present invention
  • FIG. 2 is a simplified, diagrammatic, schematic flow chart illustrating another method embodiment of the present invention.
  • FIG. 3 is an idealized, fragmentary cross-section of a bonded nonwoven fabric as made by either of the methods illustrated in FIGS. 1 and 2, with the crosssection being taken along the long or machine direction of the bonded nonwoven fabric.
  • fiberhandling apparatus 10 for forming a fibrous web of overlapping, intersecting fibers.
  • the particular type of such apparatus does not specifically relate to the essence of the present invention and may comprise carding machines, air-laying or wet-laying equipment such as garnetts, double lickerins, rando-feeders and randowebbers, paper making machines, etc.
  • the fibers used may comprise from O by weight to about by weight of textile length staple fibers having an average length of at least about /a inch up to about 1 /2 inches or even longer, say, up to 3 inches, as desired.
  • Such fibers include natural fibers, notably cotton, and synthetic or man-made fibers such as rayon, polyamide nylon 6 and 66, polyester, polyolefinic, polyacrylic modacrylic, cellulosic derivatives, polyvinyl alcohol, and like fibers.
  • the synthetic or man-made fibers have a denier of from about I to about 5, although higher deniers up to 10 or 15 are of use in special circumstances.
  • Short fibers such as wood pulp, cotton linters, and the like, or synthetic or man-made fibers in short lengths less than about /2 inch, or 4 inch, may also be included in amounts of from about 25 by weight to by weight. Such fibers have average lengths of less than about /2 of an inch and normally less than about A. of an inch, and may average as low as about l/64 of an inch, or even less.
  • a fiber is used in its normal technical or dictionary sense, such as is defined in ASTM Designation D 123-72.
  • a fiber is a generic term for the various types of matter (natural or man-made) which form the basic elements of textile fabrics and other textile structures. More specifically, a fiber is a unit of matter characterized by having a length at least about 100 times its diameter or width, and quite often greater than about times its diameter or width.

  • the primary binder B is so applied under controlled nip pressure and other print roll conditions as well as from relatively deep engraved recesses on the print roll whereby relatively larger amounts of binder are picked up for application to the fibrous web that it ideally penetrates directly and completely through the fibrous web W from one surface to the other surface and bonds the longer textile length staple fibers together to provide coherency and strength to the finished nonwoven fabric without undesirably affecting the softness, hand or drape thereof.
  • the surface coverage of such primary binders, as initially applied, is in the range of from about 5 to about 50% of the total surface of the fibrous web with from about to about 35% being preferred.
  • the binder resins used for the primary binder and other binders to be disclosed hereinafter may be selected from a relatively large group of resins, particularly of synthetic origin and are usually in the form of aqueous dispersions, and may be polymers and copolymers of polyvinyl ethers, polyvinyl halides such as plasticized and unplasticized polyvinyl chloride, polyvinyl chloride and other plastisols, polyvinyl esters such as plasticized and unplasticized polyvinyl acetate, polyacrylic resins such as polyethyl acrylate and polybutyl :acrylate, polymethacrylic resins, polyolefinic resins,

  • a secondary intermittently-closely-spaced print pattern binder area are diamond patterns (FIG. 3, US. Pat. No. 2,705,498) and diagonal and wavy line patterns (FIGS. l-4, US. Pat. No. 3,009,822). Fine or miniature dot patterns as applied by gravure shape cells are also of use.
  • the secondary binder B is so applied under controlled nip pressure and other print roll conditions as well as from shallow engraved recesses on the print roll whereby relatively smaller amounts of binder are picked up for application to the fibrous web that it does not penetrate materially into the fibrous web but basically lies primarily and predominanti; or. the surface thereof. In this way, it ties down the surface fibers, and particularly the short fibers in the areas 18 which have not been contacted by the primary binder.
  • Such tying-down of the surface fibers by the secondary binder prevents sloughing off and loss of the surface fibers and increases the resistance to rubbing and abrasion.
  • the secondary binder does not add materially to the strength of the finished nonwoven fabric or detract materially from the softness, hand or drape thereof.
  • the total surface coverage of such secondary binders as initially applied is the range of from about 40 to about of the total surface of the fibrous web.
  • the add-on of the secondary binder considering one side only, is in the very low range of from about 0.2% but normally about 2 to about 10% by weight on a dry weight basis, as determined in the finished dry nonwoven fabric. It is to be noted in passing that the secondary binder is applied not only to the areas between the primary binder sites, but also to the primary binder sites themselves.
  • the fibrous web with the primary binder and secondary binder on one side only may then be forwarded to moisture control apparatus 22 such as a heated oven or heated drying cans and brought to a desired moisture content, if desired or required.
  • moisture control apparatus 22 such as a heated oven or heated drying cans and brought to a desired moisture content, if desired or required.

  • the binder patterns, surface coverage, dry add-0n of binder, etc., are of the shape and form and in the range described previously with respect to the secondary binder B.

  • This single printing operation is to be compared to the two separate printing operations 14 and 20 of FIG. 1 and it is to be appreciated that the binder applying apparatus 14a, 20a of FIG. 2 substantially simultaneously performs the two functions carried out by the two individual binder applying devices 14 and 20 of FIG. 1.
