Definitions

  • the invention relates to a fixing insert coated with hot-melt adhesive on the basis of a knitted fabric in which only weft threads and no upright threads are embedded.
  • Fixable active inserts with weft insertion are known. For more than a decade, roughened knitted fabrics in non-offset or offset fringe laying with integrated weft threads and a hot-melt adhesive coating have been used as fixing inserts.
  • the knitting threads consist almost exclusively of fine polyester or polyamide filaments, and the weft threads are made of rayon, cotton, polyacrylic (bulked or non-bulked) or textured polyester.
  • the inserts in the direction of the wales are quite rigid.
  • the inserts can also be made elastically to a considerable extent in the direction of the rods. The highest elasticity in the direction of the rods can be achieved with a jersey binding.
  • This type of insert is usually roughened with a large number of rough passages, in order not to get any setback of the adhesive and to improve the volume of the insert.
  • Roughening is costly and, in addition, uneven rough nests and gathers often occur during roughening, the more elastic the goods are in the longitudinal direction.
  • the fixation pattern can also become wavy and uneven when the composite of outer fabric and insert is pulled at an angle.
  • inserts with weft insertion often also have excessive thermal shrinkage in the longitudinal direction, which can lead to shortening when passing through the fixing press or to undulating detachments when the plate press is opened.
  • a certain improvement of the insert has been achieved through the use of polyacrylic or polyester in the weft, if careful attention is paid to low tension when coating.
  • the object on which the invention is based is to create a particularly light-weight fixing insert of the type mentioned at the outset, with which the above disadvantages can be avoided.
  • a fixation insert coated with hot-melt adhesive on the basis of a knitted fabric with embedded weft threads made of textured synthetic yarn, preferably polyester or polyamide yarn, which are embedded in each course of the knitted fabric, which is characterized in that the yarns of the knitted stitch are textured synthetic yarn, preferably are textured polyester or polyamide yarn.
  • a preferred embodiment of the fixing insert has an elasticity at a load of 200 g / 5 cm on a 5 cm wide and 100 cm long strip of 8 to 30% in the weft direction and from 5 to 10% in the warp thread direction. This can be achieved in the shrinkage treatment following the knitting process by compressing the textured weft and warp threads to a high elasticity and during the subsequent coating, make sure that no or only a slight tensile stress is applied in the longitudinal direction.
  • This low tensile stress can be achieved, for example, by loosely placing the weft-elastic and warp-elastic insert paste-coated in screen printing on a dryer belt before drying and sintering the paste print and, after drying and sintering in a hot air dryer, loosely fed to a cooling unit and then wound up.
  • Known equipment methods are used to adjust the high elasticity in the weft and warp (longitudinal) thread direction, in which a stress-free shrinking treatment is carried out under the action of dry heat, superheated steam or hot water.
  • the raw insert is fed stress-free through a hanging loop dryer at temperatures of 150 to 180 o C, in which both the weft and the warp threads shrink to the required elasticity.
  • the coating can follow directly.
  • the shrinking treatment can also be carried out with superheated steam, which expediently also takes place in the inclined stack on a conveyor belt.
  • the drying can then either in the hanging loop dryer, be carried out on a stenter with a conveyor belt or a belt dryer. This is followed by the coating.
  • the hot melt adhesive is coated in a grid-like manner on the knitted fabric.
  • the coating is preferably carried out by means of a dot coating applied by screen printing with hot-melt adhesive pastes, with a two-layer coating consisting of a screen printing base layer and a powder scattering layer placed thereon being particularly preferably used.
  • the hot melt adhesive used for the coating is preferably copolyamide, copolyester or low-pressure polyethylene.
  • the applicable screens advantageously have a point density of 40 to 180 / cm2. In the best case, the application quantity is 8 to 15 g / m2.
  • fixation inserts according to the invention can also be used, for example, as fixable blouse or shirt inserts.
  • either low-pressure polyethylene or at least up to 60 o C wash-resistant copolyesters are used as hot melt adhesives, since blouse or shirt inserts are washed at an elevated temperature.
  • the point density of the hot-melt adhesive grid is advantageously in the range from 120 to 180 / cm 2 for this purpose.
  • the fixing insert according to the invention is predestined for moirefree coating, with a very uniform adhesion in the fixing image with outer materials and a completely homogeneous, smooth surface image also in the diagonal pull in the fixing compound with outer materials.
  • a respective selection of the grid pattern is thus superfluous, especially since the fixing insert according to the invention enables the coating points to be formed very uniformly.
  • the high abundance of the insert also makes an additional rough construction unnecessary in most cases. If it should be useful in individual cases, it is preferably carried out on the raw material. Instead of being roughened, the goods can also be sanded.
  • fixation insert can also be used with raincoats.
  • the fixing insert is explained below with reference to the single figure.
  • the construction of a bi-elastic fixing insert from a knitted fabric with weft insertion is shown.
  • the stitching is not offset.
  • Weft threads (1) made of textured synthetic yarn, e.g. Polyester or polyamide yarn are in each stitch row of the knitted fabric (2) made of textured synthetic yarn, e.g. Polyester or polyamide yarn, embedded.
  • the insert is coated with coating points (3).
