Definitions

  • the present invention relates to nonwovens of synthetic continuous filaments, at least part of which have modified surface properties, their manufacturing process and their applications.
  • the present invention relates more particularly to nonwovens of continuous filaments used as backing for floor coverings or carpets with quilted or tufted pile, at least part of said filaments having a modified surface, thus facilitating the penetration of needles during the stitching of pile threads. in the background.
  • nonwovens of continuous filaments generally of polypropylene or polyester as funds or supports for stitching bristles is well known.
  • polyester supports are used in particular when one wishes to produce particularly stable carpets such as carpet tiles or carpets printed in strips with prints with patterns connectable from one strip to the other, again requiring supports high dimensional stability both during processing: stitching, dyeing, printing, reverse coatings ... and for their behavior after installation. They are also used for the manufacture of moldable tufted carpets for automobiles because of their good elongation at break, their resistance to tearing as well as for their good thermal resistance.
  • the solution most often proposed consists in spraying the nonwoven or the filaments during their manufacture with a lubricating product; the nonwoven as well lubricated thus being able to be penetrated by the needles without damage during the pricking of the hairs.
  • a lubricating product such processes are described, for example, in the French patent applications published under Nos. 2,174,290 and 2,245,807, in which a polysiloxane type product is used.
  • the object of the present invention is to propose a manufacturing process, presenting a simple, economical answer to the problem posed of maintaining the qualities of the nonwovens during their penetration by needles during the stitching of the hairs.
  • the subject of the present invention is nonwovens of synthetic continuous filaments obtained by melt extrusion, characterized in that at least 50% of the filaments contain from 0.1 to 3%, preferably from 0.5 to 1.5%, of a polyorganosiloxane introduced into said filaments during their manufacture.
  • the present invention also relates to a process for manufacturing the above nonwovens, characterized in that, before the extrusion of the polymer melt for the production of filaments by passing through the orifices of a die, a polyorganosiloxane type silicone oil in the proportion of 0.1 to 3%, preferably 0.5 to 1.5% relative to the polymer, in the molten mass thereof and for only at least 50% thereof .
  • the present invention also relates to the use of nonwovens thus obtained for the usual applications and more particularly as the background of floor coverings with pitted hairs.
  • the filaments can be of any polymer, copolymers or blends of synthetic polymers such as those based on polyester, polyolefin, polyamide. It is obvious that the polymers can be used alone or with others for the production of bimetallic filaments of the core-sheath or side / side type. It is also possible to use polymers of the same chemical nature but of different presentation: thus polyesters such as polyethylene terephthalate of butylene glycol, polyamides such as polyhexamethylene adipamide or polycaprolactam, polyolefins such as polyethylene or polypropylene; in the present invention it will be more particularly a question of the use of polymers based on polyester.
  • the polyorganosiloxane used is preferably chosen from oils such as polydiorganosiloxanes and, preferably, polydimethylsiloxanes with molecular weights from 1000 to 250,000 and preferably located between 7,500 and 70,000 corresponding to respective dynamic viscosities of 50 to 10,000 mPa.s. These oils are non-functionalized polydimethylsiloxanes. They are chemically and thermally stable at the melting / spinning temperatures of the polymer. The rate of introduction of silicone oil relative to the polymer can vary between 0.1 and 3%, preferably 0.5 to 1.5%.
  • the incorporation of the product into the polymer can be carried out before or during the polymer drying phase (discontinuous process in which one starts from polymers in the form of "granules" and which it is necessary to condition before use) by coating or by injection, or during or after the polymer melts in the body or the nose of the extruder, in general in any transfer zone of the molten polymer before its transformation into filaments.
  • the product can be introduced into the polymer stream feeding the extruder by means of a volumetric dosing pump.
  • a mass dosage is, of course, entirely applicable to the operation.
  • the product can be introduced into the whole of the polymer or polymers used or only in a part of the latter, the preservation of the desired properties as regards the stability of the nonwoven and its ease of penetration by needles being carried out with at least 50% of the filaments containing the product.
  • the product can be introduced into the whole of the polymer or polymers used or only in a part of the latter, the preservation of the desired properties as regards the stability of the nonwoven and its ease of penetration by needles being carried out with at least 50% of the filaments containing the product.
  • nonwovens described in the French patent published under No. 2,546,537 of the applicant in which two polymers based on polyester are used: polyethylene terephthalate polyterephthalate and polyterephthalate are preferably used butylene glycol.
  • the nonwovens of the present invention are used for all the usual textile or technical applications of nonwovens either alone or mainly as a support for nonwovens with stitched pile. They can be associated with other nonwovens and, possibly, reinforced with threads parallel to each other, preferably in the length direction; they can be subjected to any manipulation of embossing, forming, molding, impregnation, coating, etc ...
  • thermobinding The penetration force measurement of a row of tufting needles in the sheet consolidated by thermobinding is carried out as follows:
  • 3 strips of SINGER tufting needles serial number 82.753 each comprising 12 needles are welded side by side on the same line forming a row of needles 9 cm wide.
  • This assembly is fixed on the mobile jaw of a dynamometer and penetrates (at the speed of 1000 m / min) into the fixed nonwoven surface stretched on a suitable device perpendicular to the movement of the needles.
  • test is carried out on a SINGER-COBBLE machine with 1/10 "gauge needles, using a continuous multifilament crimped 1100 dtex / 88 twist strand Z 150 x 2S 150 45, 40 points tightening, as a pile thread.
  • the tablecloth is needled on a single impact needle-punching machine at the rate of 50 perforations / cm2 with SINGER needles of 40 Rb gauge 15 mm of penetration.
  • the sheet is then thermobonded by passing in "S" on a calender with two heating rollers at 230 ° C, the pressing force between the rolls is 12 daN / cm and the total contact time of the sheet on the hot rolls is 9 seconds, then cooled and rolled up.
  • the dosage of silicone oil which has exuded on the surface of the filaments gives a silicone content of 0.05% relative to the weight of the sheet.
  • the amount of silicone relative to the weight of the sheet being 1%.
  • the penetration force of the needles is, according to the laboratory test, 23.6 daN for the sheet without silicone and 15.7% daN for the sheet obtained as above indicating, without ambiguity, the difference in forces penetration and the advantage of using the silicone product.
  • the tufted carpet has mechanical properties and sufficient stability to be transformed, after coating bitumen on the back, into tiles for flooring.
