Definitions

  • the oldest method consists in subjecting such filaments to an overtwist, which is set, generally by a thermal treatment, and then to an untwisting, these successive operations being carried out continuously if the falsetwist process is employed.
  • a heated yarn is passed over a knife-edge along an acute-angled path, of which the apex is situated at the knife-edge.
  • stufier crimping consists in stufiing the yarns under pressure in a confining crimping chamber provided at its outlet with a tiltable or hinged flap or other counterpressure device, the deformations obtained being set by thermal treatment, usually within the crimping chamber.
  • the stufier crimping process has the advantage that it gives a high-bulk yarn having no loops (which often give the made-up articles a rough feel) and of which the elasticity, which is appreciably lower than that of yarns treated by the first two processes above referred to, is very suitable for the production of many articles of clothing, notably sweaters.
  • the present industrial application has the disadvantage that it gives a yarn whose filaments have an inphase crimp and which in addition possesses irregularities in dyeing aflinity.
  • the yarn is introduced with the aid of a pair of rollers into a crimping chamber in which it becomes accumulated until its pressure is sufiicient to overcome the pressure of the counter-pressure device preventing it from leaving the chamber.
  • the apparatus employed comprises a number of moving mechanical parts, which is always a disadvantage when it is desired to operate at high speed.
  • thermoplastic filaments in which the filaments are introduced into an enclosed space with the aid of a current of fluid under pressure and at a temperature suflicient to set the filaments and in which the filaments are, under the action of the fluid, packed 3,373,470 Patented Mar. 19, 1968 under pressure into said enclosed space and forced therethrough, a part of the fluid being allowed to escape laterally in a controlled fashion through orifices in the wall of the enclosed space.
  • the process of this invention may be carried out by a very simple apparatus comprising no moving mechanical parts and enables thermoplastic filaments to be crimped at a high speed, which may reach or even exceed 1000 m./min.
  • stufi'er crimping apparatus comprising an injector having therethrough a passage for filaments, means for supplying heated fluid under pressure to said injector and in a direction to carry filaments through said injector passage, and a tubular crimping chamber communicating with said injector and having orifices at least in a central portion of the chamber wall.
  • the invention further concerns the crimped filaments obtained by means of the process and apparatus of the invention.
  • Such filaments have more especially the advantage of a high-bulk crimp free from in-phase waves between the various filaments, and a much more regular dyeing afiinity than yarns produced by the usual methods of stuffer crimping.
  • filaments are understood both single continuous filaments and groups of continuous filaments or short fibres, for example tows, yarns and groups of yarns, composed of filaments having the same or difierent count, cross-section or composition.
  • These filaments may come directly from the spinning machine or they may have undergone any preliminaryv treatment which does not interfere with the present process. They may have been, for example, crimped by another method, dyed, assembled by a slight twist not exceeding 50 turns per meter and preferably less than 20 turns per meter or twisted with higher twists, of the order of turns per meter for a yarn of, for example 500 deniers.
  • thermoplastic filaments having sufiicient strength to withstand without breaking the action of the current of fluid.
  • Such filaments are, more especially, artificial and synthetic filaments based upon cellulose acetate and triacetate, polyamides, polyesters, polyolefins, polyacrylonitrile, polyvinyl derivatives, etc.
  • the operating conditions, the temperature and the pressure of the heating fluid depend upon the nature of the filaments, their count and also their speed of travel, it being understood that the temperature applied must be such as to set the filaments under the operating conditions employed. If the speed of travel of the filaments is sufficiently high, temperatures higher than the melting point of the filaments may be employed.
  • the yarns to be crimped may be of identical or different natures.
  • a polyamide yarn may be employed to form the core and an acetate yarn to form the effect yarn.
  • thermoplastic filaments consisting of thermoplastic filaments of any nature, whether artificial or synthetic, and such in particular as those based upon cellulose acetate or triacetate, polyamides, polyesters, polyolefines or polyacryl or polyvinyl derivatives.
  • These tows may optionally comprise a proportion of non-thermoplastic filaments.
  • the total count of these tows may vary between wide limits and may reach 200,000 deniers. It will generally be between 20,000 and 100,000 deniers.
  • the count of the filaments constituting the tow may be small, of the order of 1.5 denier or less, or much higher, for example, 40 deniers.
  • the crimping treatment according to the invention may be applied to a tow already cn'mped by a conventional method; the bulk is thereby further increased.
  • the fluid employed may be, for example, hot air or, preferably, steam, under pressure.
  • the filaments wound on a support may be discontinuously impregnated with a dyeing bath and, after squeezing to the desired extent, the filaments may be driven by the current of fluid through the enclosed space in which the crimping is carried out.
  • the filaments may be brought, before being subjected to the action of the fluid, into contact with a device which deposits the said bath point by point over the entire length of the filaments. This method of operation is suitable especially when the crimping takes place continuously after the stretching in the case of synthetic filaments.
  • the filaments may be, for example, brought into contact with a roller rotating in a vat containing the dyeing bath.
  • the action of the hot fluid ensures, simultaneously with the crimping and the setting of the filaments, a rapid penetration of the dye into the interior of the latter.
  • a gaseous fluid such as hot air or steam under pressure
  • a liquid which may, for example, be water at a temperature of 80-160 C. under a pressure of about 0.5 to 7 kg./cm. or if a particular additional effect is required, a liquid exerting on the filaments a swelling, setting, dyeing or other action.
  • the injector which is a simple device for the introduction of the filaments, may be of any type and does not require any particularly accurate adjustment.
  • the tubular chamber through which the filaments thereafter passes may comprise, first a simple tubu lar passage having imperforate walls, to which is connected a coil spring, of which the controlled extenison makes it possible to adjust the dimensions of the orifices through which the heated fluid laterally escapes. By application of a lateral force to the outlet end, the latter can be readily curved to the desired extent for obtaining optimum pack-

  • Some of the fluid e.g., steam escapes from the spring, for the greater part through gaps 6 between the convolutions.
  • the permeable wall 7 canalises the steam escaping through the convolutions of the inlet end of the spring thus contributing to an increase in their temperature.
