Definitions

  • the invention relates to a carrier sleeve for cross-wound bobbins and cross-wound packages for bleaching and dyeing shrinking yarns, consisting of a self-contained strip made of a porous, elastic nonwoven fabric made of synthetic fibers and / or continuous fibers which are connected to one another.
  • a carrier sleeve of the type mentioned above is known from DE-OS 22 47 751. It consists of a thick-walled hollow cylinder or hollow cone made of an elastic nonwoven fabric, the wall thickness of which is dimensioned such that the recorded yarn package is not impaired its reduction in diameter resulting from the munition is safely maintained from the start.
  • the material cost share of such a carrier sleeve is relatively high because of the large fiber volume, which is perceived as unsatisfactory.
  • the shrinkage-related compression of the wall thickness can result in a reduction in the pore volume and in particular the pore radii, which has a disadvantageous effect on the flowability and thus on the uniformity with which the individual layers of the yarn package applied are acted upon by the treatment liquor.
  • the invention has for its object to develop a carrier sleeve of the type mentioned in such a way that the disadvantages mentioned no longer occur with a reduced material cost share in the manufacture.
  • the nonwoven fabric of the proposed carrier sleeve is constructed in two layers and consists of an upper and a lower layer, the lower layer having a pleating oriented parallel to the longitudinal direction and the upper layer covering the folds formed by the pleating on the outside and in the area of the largest diameter the folds are firmly connected to the lower layer.
  • the gauze wrap rests on the continuous, self-contained outer surface of the top layer, which consists of a soft, lightweight nonwoven with a particularly high permeability to liquids.
  • the flexibility is determined so that there is a good adaptation to the innermost layers of yarn of the wound package. This is determined in an excellent manner, and slipping in the axial direction at the undesired point in time can be largely ruled out.
  • the pleating of the lower layer which is firmly connected to the upper layer, achieves a pressure which is exerted on the innermost layers of yarn and which is largely constant over the entire path of shrinkage of the yarn package which occurs during the treatment.
  • undesirable signs of defonning for example flattening of the innermost layers of yarn, are thereby reliably avoided.
  • the treatment liquor can simultaneously apply all layers of the wound yarn with the same intensity, which is of great practical importance in terms of ensuring uniform treatment. In this way, for example, uneven staining of certain yarns is reliably avoided.
  • the ability to flow through the nonwovens used is favored by the small thickness of the top and bottom layers. It should not exceed a range from 0.2 to 2 mm and should preferably be 0.2 to 0.8 mm.
  • the bending stiffness of the lower layer should exceed that of the upper layer, preferably three to six times.
  • a corresponding design ensures, on the one hand, a particularly good conformability of the top layer to the innermost layers of yarn and, on the other hand, a particularly balanced contact force over the area of shrinkage which occurs with common yarns.
  • the top layer has a roughened outside.
  • the roughening can consist of fibers protruding from the surface, as can be achieved, for example, by a needling process carried out from the inside, and / or from the sintered-on particles of a scattered or printed powder.
  • This is preferably a polyamide powder with a diameter of 100 to 400 ⁇ m, based on the largest cross section.
  • the pleating of the lower layer can be designed differently and, for example, can be both sharp-edged and rounded in the area of the inner and / or outer circumference.
  • the sharp-edged design ensures a more precise definition of the yarn package picked up, while the rounded design ensures even contact forces with larger shrinkage paths.
  • a combination in which, for example, the inner folded edges are sharp-edged and the outer folded edges are rounded, allows both advantages to be combined in a favorable manner.
  • a reverse design, in which the inner folded edges are rounded and the outer folded edges are sharp-edged, is also expedient, depending on the circumstances of the individual case.
  • the upper and lower layers are preferably connected to one another by welding or adhesive zones.
  • Mutual sewing has proven to be technically more complex and has the further disadvantage that the ends of the fibers of the upper and / or the lower layer, which preferably extend in the circumferential direction, are insufficiently rigidly integrated.
  • the Sdz guest- or adhesive zones can be designed continuously.
  • the ratio of the mutual distance between the welding or adhesive zones and the depth of the pleating, measured in the radial direction, should preferably be 0.2 to 4.0, preferably 1.5 to 2.5.
  • the ratio determines the effective in the triangle of forces Seed forces, which is formed from each of the folds open to the outside and the section of the upper layer bridging them.
  • the folding surfaces are subjected to a pressure load which extends parallel to their direction and which, depending on the configuration of the folding edges, can be superimposed by a bending load. Good stability is achieved within the specified range with low material consumption.
  • FIG. 2 The starting material for producing a carrier sleeve according to FIG. 1 is shown in FIG. 2.
  • This consists of the pleated lower layer 1, which is connected to the upper layer 2 in the region of the welding zones extending parallel to the folded edges.
  • the material is rolled up in such a way that the pleating 1 forms the inside and is welded, glued or sewn to form a cylindrical carrier sleeve in the region of the outer circumference.
  • a tapered design with a corresponding design of the folded edges is easily possible.
  • the carrier sleeve consists of a pleated underlayer made of a rigid first nonwoven and an associated upper layer made of a second nonwoven, which has a soft, flexible handle in addition to a high surface roughness.
  • the first nonwoven is a polyester spunbond with a basis weight of 200 g / m 2 and a titer between 10 and 12 dtex.
  • the individual filaments are endless and tangled, which results in equivalent physical properties in every direction, in particular a balanced tensile strength and elasticity.
  • the thickness is 0.5 mm.
  • the second nonwoven is a soft, flexible crepe fleece with a good surface roughness, which guarantees optimal yarn adhesion when winding the yarn.
  • the second nonwoven fabric consists of 30% viscose fibers with a titer of 1.3 and a length of 40 mm, 10% of polyester fibers which have a length of 60 mm for a titer 3.3 dtex and 60% of nylon fibers, which have a length of 51 mm with a titer of 3.3 dtex.
  • the pure fiber content is 35.8 g / m 2 .
  • the fibers are predominantly oriented in the circumferential direction and bonded to one another by 19.2 g / m 2 of a binder applied in foam form.
  • the thickness is 0.4 mm.
  • the nonwoven fabric was needled from below and sprinkled on the outside with 24 g / m 2 of a polyamide powder, which was sintered through a thermal aftertreatment.
  • the first nonwoven fabric is passed through a pair of toothed pressure rollers at a temperature of 120 ° C. and is thereby pleated, which results in a mutual spacing of the individual folds of 8 mm at a pleating depth of 4.2 mm.
  • the profile of the folded edges is restricted on both sides.
  • the flat, second nonwoven fabric is applied to the corrugated material thus obtained.
  • the thermal welding along the folded edges is carried out in the manner shown in Figure 2, i.e. made without significant change in shape of both nonwovens.
  • the material obtained is cut to a specific format depending on the abrasion of the desired sleeve, rolled up into a hollow cylinder with folds pointing inwards and extending parallel to the axis in accordance with FIG. 1, and welded in the area of the outer circumference in the axial direction.
  • the sleeve obtained can be used immediately.
