Definitions

  • the overall fabric structure and, hence, the performance characteristics are substantially affected by the use of a high percentage of continuous filament fibers in the reinforcing layer, and the initial formation using, but subsequent meeting of a relatively high amount of fusible fibers.
  • reinforcement and abrasion resistance in terms of minutes to hole formation are shown, there is no recitation of surface tie-down of the fibers and no apparent effort to achieve surface tie-down with a minimum of effect on the overall fabric structure and performance characteristics.
  • the conjugate or fusible fibers are introduced before the base fiber web is entangled.
  • the fusible fibers are not entangled into the base layer, it is essential that the fusible fibers and base fibers be selected so as to effect specific adhesion of the fusible fibers to the base fibers following heat treatment.
  • the essence of the invention in its broadest aspect, is the provision of thermobonded entangled network of fusible fibers and base fibers, on one or both surfaces of the fabric to achieve good surface abrasion and low linting or fraying of surface fibers without substantially effecting the fabric characteristics of the base layer in forming the final fabric.
  • a dual rotor mechanism 32 of the type disclosed in Ruffo et al patent 3,768,118 is used to provide a web 12 in which the majority thereof consists of base fibers 14 disposed atop a layer of fusible conjugate fibers 16.
  • the dual rotor mechanism is schematically illustrated, and as will be apparent from a review of the 'l18 patent, it can readily be adjusted to provide the desired web composition.
  • the dual rotor apparatus is fed by cards 34,36 containing fusible conjugate and base fibers 16,14, respectively.
  • the card 35 is used to provide the fusible conjugate fibers 16.
  • the card 36 is used to provide the base fibers 14 such as suitable natural or synthetic fibers.
  • the conjugate fibers employ high density polyethylene that has a density of at least about 0.94 and a melt index .("M.I.") by ASTMD-1238(E) (190°C, 2160 gms.) of greater than 1, preferably greater than about 10 and preferably about 20 to about 50.
  • the fibers will be composed of about 40 to 60 weight percent, and preferably 45 to 55 weight percent, polyester, the remainder being polyethylene.
  • the important factor in selecting the heating conditions for optimum bonding when using conjugate fibers is to heat only the low melting point component to at least its melting point, but not to such a temperature that the high melting point component of the conjugate fibers or the base fibers could melt.
  • the conjugate fibers retain their integrity, whereby the fibrous characteristics of the surface of the fabric is retained.
  • the stiffness and loss of absorbency that can result from the total melting of fusible fibers, whereby the fibrous structure is destroyed and the remaining interfiber spaces or capillarity of the fabric is filled with the melted thermoplastic material, is avoided.
  • the thermal bonding step can be performed by passing the web between heated restraining belts, which apply moderate pressure, or between heated embossing or calendering rolls, which apply heavier pressure. With these latter methods, some compaction and densification of the web takes place. However, application of pressure increase the number of fiber contact points and thermal bonds.
  • a card 46 is disposed downstream of the dual rotor mechanism to provide the web of fusible fibers 44 on the web 12.
  • Such a fabric is disclosed and described in Figure 5, herein below.
