Definitions

  • the present invention relates to a process for the production of multifilament yarns from predominantly polyvinyl chloride. More particularly, the invention relates to such a process comprising the steps of feeding a melt of predominantly polyvinyl chloride to a spinner, extruding the melt through a spinneret by means of extrusion orifices to form the multifilament yarns, then cooling and then winding the continuous filaments.
  • this is done using a solution of mostly post-chlorinated polyvinyl chloride in a volatile solvent, such as acetone, so that it is easy to prepare a spinning solution which can be spun either by the wet-spinning process or by the more frequently used dry-spinning process.
  • a volatile solvent such as acetone
  • the dope dissolved in the volatile solvent is forced through a spinneret into a spin shaft heated gently with warm air.
  • the solidification of the filaments is done by evaporation of the solvent, which can then be recovered by condensation and filtering to almost 100%.
  • the melt spinning process is usually reserved for monofilament yarns which find use, for example, as bristles or the like.
  • a melt spinning process in which monofilaments of polyvinyl chloride or post-chlorinated PVC or vinyl chloride copolymers are obtained is described, for example, in US Pat. No. 6,312,804.
  • a monofilament of a mixture of vinyl chloride and vinyl acetate and a thermal stabilizer is spun, which is particularly suitable for applications as artificial hair or doll hair.
  • the monofilament of US 6,312,804 is obtained according to Example 1 to 5, by first the molten vinyl chloride mixture is melted and then pressed through a spinneret. In this case, a strand is obtained, which is guided into a heated cylinder and is then spun out into a monofilament. The monofilaments thus obtained can finally be drawn. Monofilaments with finenesses between about 50 and 100 denier (56 to 110 dtex) are obtained in this way.
  • melt-spinning of relatively coarse-denier monofilaments of polyvinyl chloride generally proceeds unproblematically, multifilaments can only be obtained with difficulty by means of melt-spinning processes or with uneven properties. The reason for this is probably the too low melt viscosity of the polyvinyl chloride, which leads to the fact that the relatively thin single filaments of a multifilament yarn tear easily during the spinning process and thus do not allow a satisfactory melt spinning process.
  • JP 2001-200424 attempts to solve the problem described by proposing a method for spinning a filament yarn based on polyvinyl chloride, which is characterized in that the outlet of the melt spinning unit is divided into three paths, through which the melt with a specific shear rate is pressed. It will be in a stable, largely spinnbruch sheer process "multifilament" obtained consisting of three individual filaments, with a titer - after winding and stretching - each about 67 dtex.
  • multifilament obtained consisting of three individual filaments, with a titer - after winding and stretching - each about 67 dtex.
  • the method described in JP 2001-200424 is in principle also a method for melt-spinning multifilaments, the number of individual filaments is structurally limited.
  • the outlet of the melt spinning unit is divided into three paths, resulting in three individual filaments, and certainly a further division into perhaps four or five paths would still be possible, but certainly costly and expensive.
  • the determination of the values for the spinning delay is carried out as follows.
  • the spinning distortion SV itself is defined as the ratio of Winding speed Vwic k i e r and the discharge speed (or ejection speed) of the melt from the spinneret VAustri t t-
  • the winding speed Vwickier is the peripheral speed of the bobbin on the take-up unit.
  • the exit speed V Aust ri t t is se about the throughput of the melt through the nozzle mou and their geometry (surface) expressed by the total area of the individual holes A B ⁇ h approximations of the nozzle, and the density of the PVC melt at the melt temperature as follows determined:

  • ⁇ pvc density of the PVC in g / cm 3
  • Duse mass flow of the melt through the nozzle or delivery in g / min
  • a tion SSoH e n total area of the bores of the nozzle in cm 2
  • the spinning delay is at least 40: 1, more preferably at least 50: 1.
  • a ratio of about 150: 1 has proved favorable.
  • predominantly polyvinyl chloride are meant those melts which consist of at least 90% by weight of PVC, optionally chlorinated PVC, but preferably more than 95% by weight.
  • the polyvinyl chloride usually contains a heat stabilizer, generally in proportions of about 0.2 to 5% by weight.
  • this heat stabilizer preferably consists of tin compounds, e.g. Tin mercapto compounds. Particularly preferred is butyltin mercaptide.
  • the tin compounds do not lead to charring at the temperatures necessary for a good spinning process.
  • the spinning process can be carried out particularly advantageously if the polyvinyl chloride to be spun has a Shore hardness of at least 50.

Abstract

L'invention concerne un procédé de production de fils multifilaments principalement constitués de chlorure de polyvinyle, lequel procédé consiste à introduire une masse fondue, principalement constituée de chlorure de polyvinyle, dans un dispositif de filage, à extruder cette masse fondue à travers une filière au moyen d'orifices d'extrusion de manière à former les fils multifilaments puis à refroidir les fils continus et à enrouler ces derniers. Ce procédé se caractérise en ce qu'un étirage de filage, représenté comme le rapport de la vitesse d'enroulement des fils multifilaments sur la vitesse de sortie de la masse fondue au niveau de la filière, est réglé pendant le filage, lequel étirage est d'au moins 25 : 1.
