Definitions

  • the present invention relates to a process for obtaining patterns by embossing on a vertical needle punched with thermoplastic fibers, the method consisting, in known manner, in subjecting the looped face of the needle punch to the action of an embossing cylinder whose depth of etching is less than the height of the needled loops, the embossing cylinder being brought to a given temperature and the counterpart also being heated.
  • a method is already described in document US-A-3,997,946.
  • the Applicant has set itself the goal of developing a process for obtaining special effects and in particular structured effects or "patterns" on this type of vertical needle punch, a process which it is possible to implement as late as possible in the manufacturing chain, in particular to allow product differentiation just before delivery to resellers.
  • the support which one wishes to emboss is an article having relatively large pile heights (about 3 mm), as is the case with vertical needles, it seems essential, in order to achieve interesting and permanent structural effects, using embossing cylinders whose engraving depth corresponds essentially to the height of the bristles.
  • the engraving depth of the embossing cylinder may be less than the height of the bristles, but it does not provide any precision on the temperature to which the embossing cylinder is brought.
  • the Applicant has surprisingly determined that it is possible to obtain very interesting structured effects on a vertical needle punch, without harming its appearance and feel, playing not only on the depth of the engraving, but also on the temperature of the embossing cylinder and its counterpart.
  • the heating temperature of the embossing cylinder is significantly lower than the temperature of softening of the needled thermoplastic fibers.
  • the vertical needle punch is generally designated by 2, the embossing cylinder by 3 and the counterpart by 4.
  • the installation used for implementing the method according to the invention and shown very diagrammatically in FIG. 2 essentially comprises a storage and unrolling station 6 for the vertical needlework 2, a storage and unrolling station 7 of the sheet of paper 8 intended to be applied by gluing to the reverse side of the needle 2, means 9 making it possible to secure this sheet 8 to the underside of the needled 2 and an embossing cylinder 3-against-part 4 assembly intended to communicate to the vertical needled 2 the desired structural effect, according to the invention.
  • a sheet of fine denier polypropylene fibers (from 3 to 6 decitex) is prepared, which is subjected, in a conventional manner and on an apparatus not shown in the drawing, to successive carding, consolidation operations. by flat needling and looping by special needles. This produces the vertical needle 2 having loops or bristles 5a of about 3 mm in height.
  • This needled 2 is then passed continuously over a smooth calender 9 which provides the laminating on the reverse side 4 of the needled 2 of the backing paper 8 coming from the roll 7.
  • a means of applying glue (not shown in drawing) is planned before arrival at the grille 9.
  • the needled assembly 2 - paper 8 is then subjected to a hot embossing process by passage between the embossing cylinder 3, acting by its etching on the bristles 5a and the counterpart 4.
  • the engraving of the embossing cylinder 3 is chosen so that its depth is in all cases less than the height of the bristles 5a of the vertical needlework 2. In the present case, the depth of this engraving is from 1 to 2 mm according to the effect you want to achieve.
  • the embossing cylinder 3 is brought to a temperature between 120 and 140 ° C, a temperature much lower than the softening temperature (170 ° C) of the polypropylene fibers; the counterpart 4 is brought to a temperature of approximately 160 ° C. and the embossing action is exerted at a pressure of approximately 40 bars.
  • the vertical needle 2 After passing through the embossing device, the vertical needle 2 has the appearance shown diagrammatically in FIG. 1 where it can be seen that the part of the bristles 5b subjected to the embossing action is not completely crushed; the article therefore retains its appearance and its textile feel without observing plasticization as could be the case if the softening temperature of the thermoplastic fiber were reached, or if one worked with etching depths such as the hair 5a is crushed over their entire height.
