Definitions

  • This invention relates to a new process for manufac- -turing a fibrous sheet material simulating felt, and more particularly to a novel needled fabric and to the method of making same from normally unfeltable fibers.
  • feltable fibers Such fibers, including wool, goat hair and other animal fibers, have a substantial curl and even more important a rough surface which allows the fibers to interlock or interfelt into a felt havi-ng substantial strength. Except in admixture with feltable fibers, the vegetable fibers like cotton, the synthetic fibers like rayon, nylon, etc., and even some animal fibers cannot be felted satisfactorily because the characteristically smooth surfaces of these fibers slide upon one another too readily for interfelting. Non-woven fabrics resembling felt can be made from non-felting fibers by needling.
  • Needled fabrics suffer from a most serious disadvantage of low strength especially when the fiber bat is not very thick and heavily needled. To avoid this disadvantage many strengthening expedients have been suggested. According to one such method a fibrous fleece is placed fabric.
  • Still another method Vinvolves employment of a poten- 'tiallyfadhesiveresin inhfiber formv as part of the fiber mix, needling, and subsequently heating the rneedled fabric toj atemperature whereat the resinous fibers become ⁇ sufliciently tacky Ato adhere tof the V,other bers in the needled fabric.' Y Y.
  • Still -a further object of the instant invention 1s Vto provide a process for producing a needled fabric of predetermined thickness, strength and dimensional stability.
  • the process of the instant invention con ⁇ templates: forming a fleece of fibers, coating the surface with an adhesive binder to form a thin surface layer of bonded fibers, drying said surface and then needling the unbonded fiber fleece through the layer of dried adhesive to form a needled fabric.
  • a single needling operation on each side is suflicient to achieve good felting or interlocking of the fibers, and to create a needled fabric of great softness and drape, yet having considerabl strength and dimensional stability.
  • the needling makes multitudinous perforations in the adhesively bonded layer of fibers and actually masks this bonded layer from visual discernment thereof, the integrity of the bonds appears in the final needled As compared to the same fabric made without a surface layer bonded by adhesive, there is substantially increased strength and dimensional ⁇ stability depending largely upon the amount and character of the adhesive bond.
  • the strength land dimensional stability of the ultimate needled fabric can be predetermined within wide limits according to which of the several preferred modes of the instant invention is employed, and the. amount o-f adhesive employed. By and large, at least 30% of the strength and dimensional stability of the needled fabric is derived from theadhesive, and the balance from the needling action.
  • Figure 1 is a diagrammatic view of a fiber fleece with one surface sprayed with a liquid binder.
  • Figure 2 is a vertical view of the sprayed fiber lfleecev of Figure 1 after needling.
  • Figure 3 is a vertical view of two lleeces, each sprayed on one side and plied together with the sprayed surfaces placed facerto face.
  • Figure 4 shows the two plied fleeces of Figure 3 after needling.
  • Figure 5 is a vertical view of two plied ileeces both sprayed on each side.
  • FIG. 6 is a diagrammatic View of the two plied lleeces of Figure 5 Vduring needling.
  • y f 4 Referring now to Figure 1 of the drawing, there is shown a fiber fleece 7 such as produced by air'deposition or by cards or garnettes. One side or surface of the fleece is shown spray coated with a liquid binder and thereafter dried.
  • Figure 2 shows the same coated fleece 7 after needling. The needling operation has forced individual fibers 3 through the bonded surface layer 6, causing fibers 8 to protrude to the reverse side of layer 6, and in effect form a new outermost surface layer 9, hiding the existence of adhesive bonded layer 6 from visual discernment.
  • v v
  • both surfaces of the initial fleece may be coated with a binder prior to needling.
  • a particularly desirable variation is illustrated in Figures 3 and 4 where two layers of fleece 17, 17, each having an adhesive coated outer Ybels 8 vfrom the upper vlayer H17 into lower layer 17', and a second needling in the opposite direction forces fibers from layer 17 into layer 17 thereby thoroughly interlocking 17, 17' into an integral needled fabric with an adhesively bonded ⁇ layer embedded at the center of the needled fabric.
  • a thinner spray of binder liquid may advantageously be applied to one or both outer surfaces prior or after needling in order to prevent loose, easily removed fibers from ybeing present on the surface of the ultimate needled fabric.
  • a pair of needles 11, i2 are diagrammatically illustrated.
  • the eece employed for the practice of the instant invention should range in weight between about 0.50 to 7.0 oz. per square yard of single layer. Heavier fabrics than 7 oz. can be built up by employment .of multiple layers in the manner illustrated by Figures 3 4. In contrast, a light but strong needled fabric can be made by needling a single layer of ileece adhesiveily bonded initially on both surfaces.
  • the eece itself can be composed of any ber: animal, like cattle hair, horse hair, wool, etc.; vegetable, like cotton, linen, plaina, cocoa, etc.; mineral, like asbestos, ⁇ glass, metal, etc.; or synthetic, like rayon, acetate, nylon, etc.; or any desired fiber mixture. Although nornfelting bers are most generally contemplated, wool and other felting fibers can be employed.
  • the binder liquid is also capable of wide variations.
  • ,It may be an aqueous or non-aqueous solution emulsion tor dispersion of adhesive or of latently adhesive material which upon drying or heating forms an adhesive bond.
  • known adhesives include: rubber (natural and synthetic), vinyl resins, isocyanate resins, ipolyamides, polyacrylates, and others.
  • suitable solvents lfor the binder liquid include water or organic volatile solvents such as lower alkanols, hydrocarbons, ketones and the like, or mixtures thereof. ⁇ iikltern'atively, no ⁇ extraneous solvent need by employed when the binder substance is a normally liquid monomer ⁇ or polymer which forms a solid adhesive in the course of drying or curing. If desired, a curing agent can be incorporated into the binder liquid to speed up setting of the adhesive during the drying or heating, In ad dition, the binder liquid can incorporate up to 35% by Weight of thermosetting resins such as melamine formaldehyde precondensates for imparting other properties - ⁇ as desired.
  • the liquid binder is preferably applied to the eece by spraying through conventional spray nozzles.
  • the binder liquid should not excessively penetrate the liber lieece since the object is to form a thin lsurface layer of bonded bers.
  • the eece should be sprayed with that amount of binder liquid which will deposit non-volatile binder solids 'ranging from about 0.05 to 1 times the weight of the jeece.
  • the drying and setting of the adhesive binder can 'be accomplished by carrying the sprayed fleece over or between heated rolls with or without the application of pressure, or by carrying the lieece through a drying oven supported otherwise unpress-ured. After drying is com pleted, only the thin layer of fibers affected by the binder are chemically bonded into a thin core or stable 'layer through which free bers from the remainder of the eece are forced by subsequent needling. As has been indicated, one needling operation on each side is suiiicient to achieve a good "felting or interlocking of the tibers, and to create a strong, stable felt with great softness and drape.
  • the product can be subjected as desired to other treatments such an printing, dyeing, calendering, etc., or the like.
  • the liquid binder applied is of a thermoplastic nature
  • the needled yfabric can be subjected to heat, making the ⁇ adhesive ⁇ tacky.
  • This ⁇ subsequent .treatment will add rmness to 4 .the needled ⁇ fabric by bonding the transversely extending bers 8 to layer 6 at the needle perforations of layer 6 where fibers 8 contact the adhesive bonding the original surface layer 6.
  • the novel process of the present invention is considerably less expensive than felting.
  • a variety of fibers can be used which have no .telting properties, yet the results achieved will be very similar to those of genuine felt, especially as far aS dimensional stability kand strength are concerned.
  • the density of the Vproduct made by practice of this invention can be controlled to a greater degree than in .conventional felting or need-ling processes. The same applies to the softness and hand of the fabric as well as air permeability, all of which can be controlled to any desired degree.
