Definitions

  • the present invention relates to a method for treating textile articles or articles, produced from woven or knitted fabrics, the treatment being of the mechanical finishing type and intended to modify their structure, for example by increasing the volume, by improving the flexibility, by modifying their surface appearance.
  • Yarn producers have proposed yarns made up of continuous filaments with adherent microfilaments, obtained by star or lamellar spinning. The pieces obtained by weaving or knitting such threads are then subjected to a treatment intended to individualize the microfilaments, so that said piece has the flexibility, the feel, the voluminosity corresponding to the unitary microfilaments.
  • This individualization of the microfilaments is carried out using suitable chemical treatments in which the matrix ensuring the bonding of the unitary microfilaments, or superficially the interlamellar surface is attacked. It is in particular a treatment with soda when the microfilaments are made of polyester.
  • piece will designate all the presentations of woven or knitted fabrics: fabric or knitted fabric which has fallen out of the trade and which is in the form of a strip of very long length, part cut from such a strip or made-up item.
  • the aim set by the applicant is to propose a simplified treatment of textile pieces which not only modifies their structure without causing breakages of continuous filaments in the constituent threads of the piece or of the treated article, but also constituent yarns being continuous filaments with adherent microfilaments, realizes the individualization of the microfilaments.
  • Said method consists in treating a textile piece, resting on a support grid, said piece being made up in whole or in part of continuous filament yarns with adherent microfilaments by the action of water jets at a pressure of at least 4.10.6Pa, provided what the action of the water jets dissociates the microfilaments.
  • the method of the invention makes it possible to obtain a completely reproducible effect, in the case of simple adjustments of the physical conditions: speed of the grid, pressure of the water jets, in particular.
  • the support grid moves continuously under several ramps, each comprising a set of high-pressure water jet injection nozzles, the water pressure being identical or different from one ramp to another.
  • the part is subjected to the action of jets at increasingly higher pressures.
  • the running speed of the part being between 20 and 100 m / min, it is successively subjected to the action of four ramps of water jets at stepped pressures respectively of 4.106 to 20.106Pa.
  • Some constituent threads of the part are for example threads composed of filaments with adherent microfilaments obtained by star spinning, each filament having a titer of approximately 2dtex and comprising from 6 to 8 polyester microfilaments from 0.2 to 0.4dtex, assembled using a polyamide matrix.
  • the treatment installation 1 which will be described is suitable in particular for textile pieces, fabrics or knits, wound in the form of coils 2 of continuous strips.
  • This installation 1 comprises a set of means carrying out the positioning and the transport of the part 3, namely from upstream to downstream a shaft 4, driven by a motor not shown, on which is fitted the coil 2, rollers 5 of tension, a support grid 6 consisting of an endless belt wound and stretched between two cylinders 7,8 driven at the same linear speed as the shaft 4, the part 3 resting on the upper part 6 a of the grid 6, and finally a detour roller 9 cooperating with a shaft 10 for winding the coil 11 consisting of the part 3 treated.
  • FIG. 1 shows only two ramps 12, 13 for injecting high pressure water.
  • Each ramp is supplied by a pump 14.15 capable of working at adjustable pressures ranging from 4.106Pa (40 bars) to more than 20.106 Pa (200 bars).
  • Each ramp 12, 13 comprises a plate pierced with a set of orifices serving as injection nozzles 16 distributed on the one hand over the entire useful width of the grid 6 at the rate of an orifice every 2 mm and of somewhere else on several rows, for example three rows have been shown in FIG. 1.
  • the high pressure water leaving the injection nozzles 16 is in the form of extremely fine jets, having a diameter of the order of 100 to 150 micrometers.
  • Suction boxes 17,18 are placed opposite the injection ramps 12,13 under the upper part 6 a of the grid 6 while the ramps are located above this upper part 6 a , the nozzles 16 being directed perpendicular to the plane of said upper part 6 a and therefore to part 3.
  • the support grid 6 is a metallic grid of 100 mesh (that is to say of 100 meshes per inch) produced with wires of 200 micrometers in diameter.
  • a drying tunnel 19 is placed on the passage of the part 3 treated after the outlet cylinder 8 and before the detour roller 9.
  • a polyester fabric of about 130 g / m2 has been treated having as warp yarn a conventional yarn making 90 dtex, and comprising 136 continuous filaments, and as weft yarn a continuous filament yarn with adherent microfilaments obtained by star spinning.
  • Such a wire is shown in Figure 2A. It comprises six unitary polyester microfilaments; each microfilament 20 has in cross section the shape of an orange quarter; the six microfilaments 20 are separated by a polyamide matrix 21 having six radial branches 22 symmetrically distributed around the longitudinal axis 23.
  • Each unitary microfilament 20 of polyester has a titration of between 0.2 and 0.4dtex.
  • the treatment of the above fabric was carried out at 20m / min, by passing under four injection ramps, the water being respectively at 6.106Pa, 8.106Pa, 20.106Pa and 20.106Pa.
  • the enclosure corresponds to the distribution of the filaments and microfilaments in relation to the volume of the tissue.
  • FIGS. 3 and 4 There are other types of son with adherent microfilaments, in particular those shown in FIGS. 3 and 4.
  • a coreless wire is shown, that is to say that the bonding matrix of the four microfilaments 24 in polyester is made up of four polyamide 25 microfilaments joined to two successive polyester microfilaments 24.
  • FIG. 4 shows a thread of the lamellar type in which the polyester microfilaments 26 correspond to longitudinal sections of a filament of substantially circular section. Self-adhesion between the four microfilaments 26 is obtained due to the fact that when spinning the four strips are joined only after the polyester has cooled down for a certain time.
  • the invention is based on the use of water jets at pressures of at least 4.106 Pa (40 bars) to modify the structure of textile pieces, fabrics or knits, whose constituent yarns are already assembled between them.
  • This structural modification consists in the mechanical separation and the relative displacement of microfilaments which had, in the thread before treatment and during weaving or knitting, a certain adhesion.
