Definitions

  • the present invention relates to a process for obtaining special effects on vertical needle punched nonwoven fabric as well as the needled threads obtained.
  • the Applicant has set itself the goal of developing a process for obtaining special effects and in particular structured effects on this type of vertical needle punch, a process which it is possible to implement as late as possible in the production chain, in particular to allow product differentiation just before delivery to resellers.
  • the support to be embossed is an article with relatively large pile heights (about 3 mm), as is the case with vertical needles, it seems essential, to achieve interesting and permanent structural effects, to use embossing cylinders whose engraving depth essentially corresponds to the pile height.
  • the Applicant then surprisingly determined that it was possible to obtain very interesting structured effects on a vertical needle punch, without detriment to its appearance and its feel, by playing on two important factors: - the depth of the engraving, - the temperature of the embossing cylinder and the counterpart.
  • the process for obtaining special effects on a vertical needle punch according to the invention is characterized in that it consists in subjecting the looped face of the needle punch to the action of an embossing cylinder whose engraving depth is less than the height of the loops of the needle punch, the embossing cylinder being brought to a temperature much lower than the softening temperature of the thermoplastic fibers of the needle punch and the counterpart also being heated.
  • the vertical needle is generally designated by 2 , the cylinder engraved 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 on the reverse side of the needle punch 2 and an embossing cylinder 3- counterpart 4 assembly intended to communicate to the vertical needle needle 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 with loops or bristles 5a of about 3 mm in height.
  • This needled 2 is then passed continuously on 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 the drawing) is provided before arriving at the calender 9 .
  • the needled assembly 2 - paper 8 is then subjected to a hot embossing process by passage between the engraved cylinder 3 , acting on the bristles 5a and the counterpart 4 .
  • the etching 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 needle 2 .
  • the depth of this engraving is 1 to 2 mm depending on the effect which it is desired to obtain.
  • 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 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 bristles 5a are crushed over their entire height.
