Definitions

  • This invention relates to a fleece fabric material which has improved flexibility, feel and stretchability.
  • the present invention is based on the problem of effecting a substantial improvement in the feel and draping capacity of the fleece material.
  • This problem is solved, according to the invention, by the provision of a plurality of slits having substantially closed contours disposed in patterns, the length of the said slits being not more than 6.5 mm.
  • slit is to be construed in this specification and appended claims as relating to an elongate cut in which the dimension in the transverse direction thereof is infinitely small and approximates zero.
  • the present invention provides a fleece material which bears favourable comparison with conventional textile fabrics.
  • the slits as they have been applied in the fleece material in accordance with the proposal of the present invention, not only is its feel (draping possibility) substantially improved, but so too is its stretchability to the extent that the fleece material approximates the characteristics of textile fabric.
  • a similarity exists in the actual fleece structure in that, as in a fabrice.g. in linen weave-alternately a thread is bound and floated, so in the slitted fleece one part of the fibers is cut and another part of the fibers is uncut or bound.
  • FIG. 1 shows the scheme of a row of pattern of slits with the important references
  • FIGS. 2 to 5 show cross-sections through fleece materials with differently formed slits
  • FIG. 6 shows a special form and arrangement of the slits
  • FIGS. 7 and 8 show, in plan view or in cross-section, further slitted fleece materials.
  • the fiber fleece material designated hereinafter for the sake of brevity as materials, with so-called minislits which have such a. favourable ratio between material thickness on the one hand and length of slit, separation of slits and of rows on the other hand that the disadvantageous phenomenon aforesaid does not occur, the slits no longer being conspicuous or being almost invisible.
  • a mixture of cellulose and polyamide fibers of approximately six den. thickness and 40 mm.
  • Such fleece materials may also be provided with elastic coatings of such character as will readily allow an expansion of, for example, 3%, due to the aforedescribed slitting.
  • the slits do not gape open, and hence practically no adhesive material penetrates the slits to stick the side faces of the slits together.
  • the slits extend completely through the whole product, whilst in another embodiment the slits penetrate only partially through the thickness of the material. This latter form of slit, on lateral stretching, gives rise to the arrangement shown in FIG. 2, which latter is to be compared with FIGS.
  • FIG. 3 and 4 which show an arrangement wherein the slits are stamped or cut through the material.
  • 'FIG. 5 shows a material structure slitted from both faces, this form of slitting being favoured for thicker articles.
  • FIG. 6 shows the diagram of a material provided on one side With slits D and on the other side with slits F arranged perpendicularly thereto, the slits extending only partially through the material and imparting a two-direction expansion characteristic without continuous slit marking.
  • slits in fleece materials has the particular advantage that, because of the generally random fiber orientation, a further tearing of the slits is not to be feared as would be the case, for example, with materials not containing fibers, such as, for example, regenerated cellulose. If a certain direction of fiber orientation dominates, then it is generally advisable to form the slits perpendicularly to this direction hence to cut through as large a number of fibers as possible.
  • the slits have the generally desirable advantage of increasing the air permeability of the product. In consequence of the expansion and permeability characteristics of the material it is now possible, for the first time, to employ such fleece materials also directly in the clothing sector where formerly only fabrics, woven materials and knitted materials were usable.
  • the material is of use in the manufacture of clothing, as well as being suitable for use as a lining material for textiles, as a corset material, and also in the hitherto actual main field of fleece materials such as material inserts, shoulder pads, and the like particularly when there is a requirement of better expansion behaviour, as for example, in the inner lining of clothing made from knitted materials.
  • fleece material products made of synthetic fibers or with fibers having heat sealing properties applied thereto, as by coating or spraying with thermoplastic materials, or by insertion of a binding mass on the forming of the slits, to effect at the same time as the slits are formed a hardening of the fibers among themselves.
  • FIG. 7 shows such a fleece structure. An additional strong binding by means of the cut welding is obtained at the points M. The fiber binding is hereby considerably increased and, in addition, satisfactory additional elasticity and expansion are attained.
  • Such fleece materials may also consist of fibers having different melting points and partly of non-melting fibers. Coarser fiber fleece materials may be used with advantage for cleaning purposes, the slits carrying the cleaning mass and entrained dirt therein and permitting of a satisfactory expansion of the material so that one can draw such materials around surface edges.
  • the fleece material according to the invention is suitable not only for the described purposes but also for insulating, sound-damping, decoration and building purposes; it may also be made in the form of corrugated paper in which the slits are made preferably in the direction of the corrugations and, in fact, in the troughs of the corrugations and/or through the corrugation crest and base simultaneously crosswise to the direction of the corrugatlons.
  • fleece fabric material employed in the foregoing description and appended claims includes non-woven fabrics consisting of a continuous fleece of vegetable and/ or animals and/or synthetic fibers bonded by adhesives or by needling.
  • a non-woven fabric comprising:
  • Sheet 1 In the drawing, Sheet 1, FIG. 1, dimension "B” should be corrected to lit to the other end thereof as follows:
