Definitions

  • the fabric After the fabric has been reinforced as described it is placed on a tentering machine for stretching in the direction that the fibers run, whereby to greatly improve the surface characteristics of the reinforced nonwoven fabric.
  • the fabric thereafter is coated with a polymeric coating.
  • FIG. I is a plan view of a portion of a fiber web or batting useful in the present invention.
  • FIG. 2 is a view similar to FIG. I with the batting reinforced by stitching perpendicular to the direction of the fibers;
  • FIG. 3 is a view similar to FIG. 2 showing the opposite surface of the fabric
  • FIG. 5 is a view similar to FIG. 4 showing the reinforced web or batting after tentering.
  • FIG. 6 is a view similar to FIGS. 4 and 5 showing the fabric after coating with a polymer.
  • nonwoven fabrics from webs or battings of fibers has been known for many years.
  • Such webs or batting may be in the form of random unspun fibers or, as shown in FIG. I, in the form of substantially parallel unspun fibers.
  • the batting 110 of FIG. I with substantially parallel fibers is preferred in the present process, although the fiber parallelism is not essential thereto.
  • the fibers from which the batting I0 is made may be natural fibers or synthetic fibers of any type, although long fibers are preferable in that they yield a stronger end product. In fact, a most desirablefiber is a monofilament fiber ofsub-.
  • stantially infinite length as, for example, tow made of nylon, polyester, rayon or acetate, or any othersynthetic fiber that is extruded from a spinerette. While from a cost factor spun yarns are not desirable to the present invention, from a viewpoint of operability spun yarns can be substituted for the unspun fibers in the web I0.
  • the stitching is of the type done by knitting machines, sewing machines, tufting machines, quilting machines or the like.
  • the term stitching as used herein is in tended to cover all such and similar forms of yarn implantation.
  • the stitching in addition to having a main component running transversely of the fibers, has a component extending in a direction parallel to (or at an acute angle to) the fibers, whereby to provide for reinforcement in the direction of the fibers as well as in the direction transverse thereto.
  • a most desirable stitch for reinforcing the web or batting i0 is a tricot stitch whichaigzags on one surface of the batting and appears as a straight chain stitch on the opposite surface thereof.
  • the surface showing the zigzag stitch may be seen and in FIG. 22 the opposite surface showing the chain stitch may be seen.
  • the stitching on the web or batting ill be performed on the Elitex-Arachne knitting machine which is described and claimed in a number of patents such as, for example, US. Pat. Nos. 3,079,778; 3,310,964; and 3,309,901. These patents and others are embodied in the Elitek-firrachne machine as described in the present Elites brochure on the machine. Machines manufactured by other manufacturers and having similar characteristics are the Maliwatt and ACl-lll l Mark IV machines which may be employed in performing the present method. The particular machinery used does not form a part of the present invention and various modifications of equipment will readily suggest themselves to persons skilled in the art. Even a conventional sewing machine can be employed as could quilting machines and the like to stitch in the reinforcement yarn as already described.
  • the type of fiber to be employed in the web or batting It is a matter of choice and depends upon the proposed end use of the material being made.
  • natural such as cotton, flax, wool and silk
  • synthetic fibers such as nylon, rayon, acetate, polyester, acrylic, polyolefrn, etc.
  • inorganic fibers such as fiberglass and asbestos may be also be used.
  • the fiber density is a matter of choice well within the skill of the art.
  • the number of stitches per inch and the number of stitch rows per inch are parameters which the skilled art worker may select in accordance with the particular application.
  • the type of fiber from which the stitch yarn is made is a matter of choice, well within the ability of the skilled art worker and may be any of the fibers previously mentioned with respect to the unspun fibrous content of the batting 110.
  • Not only the composition of the stitch yarn but its physical properties are a matter of design selection and choice. Suffice it to say'the same considerations as the skilled art worker brings to bear in selecting the components and parameters for standard stitch reinforced nonwoven fabrics as illustrated in FIGS. 2, 3 and l, are brought to bear when deciding upon the components and parameters of such fabrics for use in practicing the present method.
  • the reinforced web or batting is designated by the reference numeral 16 and is shown in cross section in FIG. 4. It will be seen that such a product, which is well known, has an uneven or ribbed surface characteristic due to the fact that the batting is compressed at the points where the reinforcement stitching 12 passes therethrough. This gives a ridged or ribbed effect and it is this effect that has caused significant problems in utilizing the product 16 in the manufacture of polymericcoated fabrics. Thus, when such a fabric is coated with any suitable polymeric coating, there is a tendency, due to the unevenness of the surface 18, for the fabric surface to show through the polymeric coating and yield a clothy appearance which is undesirable and unwanted in many applications. It is this clothy surface quality which the present method is designed to reduce or eliminate.
  • the fabric is stretched in the direction transverse to the stitching 12.
  • the stretching is done in a direction parallel to the fibers.
  • the stretching can be performed on any suitable apparatus.
  • tentering machines as exemplified by the Famatex high-production, single-layer tenter, Type PRH 30, manufactured by the Famatex Company of West Germany and sold in the United States by the David Gessner Company of Worcester, Mass. may be and has been employed.
  • Other suitable tentering machines are the Krantz DZ tentering machine manufactured by H.
  • the nature of the fiber and the nature of the stitch yarn has a significant bearing on the amount of stretch that can be tolerated.
  • the type of stitch and the number of stitches per inch and the number of stitch rows per inch afi'ects the stretchability of the material.
  • the density of the nonwoven web also has a significant bearing on the stretchability.
  • the amount of stretch which can be imparted to any particular stitch-reinforced web 16 is something that can be worked out by the skilled art worker with relative ease and rapidity and is dependent mainly upon the particular reinforced web that he iys rhsrtsescisssf thsrs ar iasna sa k,
