Definitions

  • the present invention relates to a needled non-woven fabric and the method of producing such a fabric. It relates more particularly, to a lubricated non-woven fabric of the needled type which is suitable for use as the backing fabric for tufted carpet or the like and to the method of producing such a fabric.
  • the lubricant also reduces pounding and noise due to tufting operations and it prevents the tufting needles from reaching a temperature where damage to the tufting yarns may result.
  • a non-woven fabric embodying the present invention comprises a needled sheet-like web of lubricated fibers of a high strength synthetic thermoplastic material including polyolefins, polypropylenes, polyesters and the like.
  • the fibers are intermixed and entangled by the needling with portions thereof being displaced vertically relative to the thickness of the web.
  • warp threads of cotton or a similar material extend in spaced parallel relation to each other in a lengthwise or 'warpwise direction of the web adjacent one surface thereof.
  • thermoplastic fibers on one or both exterior surfaces of the web are bonded or fused into engagement with each other with the fibers on the surface adjacent the warp threads being fused or bonded to said threads.
  • the remaining fibers of the fabric are not fused or bonded together and remain mobile relative to each other.
  • a lubricant applied to the web and the fibers thereof permits a large percentage of the unfused or unbonded fibers to be deflected or pushed aside without being severed or broken in the passage of tufting needles through the fabric. As a result, there is little change in the strength of the fabric due to tufting.
  • the needled web is formed from crimped fibers of a high strength synthetic thermoplastic material including polyolefins, particularly polypropylene in staple or fibrillated (split film) form. Fibers of other synthetic thermoplastic materials such as polyesters and mixtures may be employed. Where fibers of polypropylene are mixed with other fibers, the percentage of polypropylene fibers in the mixture is preferably not less than 80%, but this will depend on the strength requirements.
  • the fibers may be in the form of a 4 /2 in. staple and may vary in size up to about 15 denier with different sizes being mixed. For example, a mixture containing six denier and 25% three denier fibers of polypropylene may be employed.
  • the fibers are deposited by a cross-lapping operation by which a large number of the fibers extend in a widthwise direction relative to the fabric and when the fibers are not damaged or broken by the tufting needles, the tensile strength in the width of the fabric can be maintained with acceptable limits.
  • FIG. 3 is a section view taken along line 33 of FIG. 1 and is also drawn to a larger scale than FIG. 1;
  • FIG. 7 is a side elevation of the machinery of FIG. '6.
  • Each of the cross-lappers 24 is supplied with fibers from a garnet or carding machine 25 and each of the garnets is in turn supplied with fibers from a secondary pair of cross-lappers 26 to which fibers are supplied from another set of garnets 27.
  • Feed boxes 28 supply fibers to the second set of garnets. Fibers are delivered to the feed boxes from the usual blenders and pickers (not shown).
  • the needled and fused web then passes around guide rolls 38, 39 and 40 and is guided in a path which brings the lower surface of the web into contact with the surface of a padding or lick roll 41 which is rotatably mounted in a receptacle 42 containing an aqueous solution of a lubricant.
  • a method of producing a needled non-woven fabric which comprises the steps of depositing fibers at least some of which are of a thermoplastic material, in a loose condition on a band of parallel, unconnected spaced warp threads;
  • the method of claim 1 comprising the step of applying an aqueous solution containing a lubricant to at least one surface of the needled web of fibers and warp threads.
