  • This invention relates to textile treating apparatus and more particularly to an apparatus for conditioning a tow of filamentary material lformed from a synthetic composition such as acrylic polymers or the like with a pressurized fiuid such as steam.
  • the polymer is spun by a wet spinning process into a plurality of continuous filaments which form what is generally termed a filamentary tow.
  • this continuous filamentary tow it is subjected to various conditioning operations, one of which involves attenuating or stretching the heated tow filaments so as to orient the molecules of the filaments and align them in the direction of the filament axis.
  • This stretching of the heated tow filament imparts certain highly desirable physical characteristics to the filaments, among which are high tensile strength and low denier.
  • these stretched filaments possess lexcellent physical properties when formed into yarn and lfabric, they are prone to fibrillate or split off into fibrils when subjected to abrasion or other forms of strain. This fibrillation causes abraded portions of the fabric formed from these filaments to appear lighter in color than the remaining parts, thus giving the illusion of wear. It is thought that the fibrillation results from the internally strained condition of the molecular structure of the filament created during the stretching operation.
  • the stretched filaments In addition to this proneness to fibrillation inherent in the internally strained filaments, the stretched filaments also have a high residual shrinkage capacity and tend to shrink on subsequent -heating at elevated temperatures. Furthermore, as a result of the stretching operation, the filament extensibility is decreased, thus limiting the use of such filaments in textile operations such as knitting and weaving where a high extensibility is desired.
  • annealing has been found to reduce or substantially eliminate fibrillation while increasing extensibility and generally improving the quality of the filament.
  • the tow is processed in a batch-type operation which involves loading large quantities of tow material into autoclaves or similar pressure vessels wherein it is subjected to steam under pressure for an extended period of time while in a relaxed condition. While this method of annealing lamentary material gives generally satisfactory results, it suffers several significant drawbacks. In the first place, it is well known that filaments formed from acrylic material such as acrylonitrile polymer tend to take on a yellow hue when subjected to elevated temperatures over an extended period of time.
  • this batch-type of annealing process is quite time consuming, since it requires the interruption of the substantially continuous operation involved in the manufacture of synthetic filamentary material while the large batches of vfilament are placed in the autoclave, brought up to proper pressure and temperature, cooled and then removed by hand for subsequent processing.
  • batch-type proces-s is generally expensive from the standpoint of both time and labor expended, and particularly with regard to the initial investment and maintenance of large and bulky apparatus which requires considerable floor space.
  • a primary object of this invention is to provide a novel apparatus -for the treatment of textile material.
  • Another object of this invention is to provide an apparatus for annealing internally strained filamentary material in an intermittent manner which is both rapid and efficient.
  • a further object of this invention is to provide such an apparatus for semi-continuously annealing a row of filamentary material formed from a synthetic composition such as acrylonitrile polymers and the like.
  • Another object of this invention is to provide a new and novel apparatus for annealing lamentary material formed from acrylonitrile polymers and the like which substantially eliminates the tendency of the filament to discolor, and consequently produces a relatively White annealed textile product.
  • a further object of this invention is to provide an apparatus for annealing filamentary material which subjects successive portions of the material to a pressurized fluid, maintaining a seal about the material and preventing the discharge of the pressurized fiuid from the apparatus into the surrounding atmosphere.
  • Still another object of this invention is to provide an apparatus for annealing tow by means of pressurized steam wherein said apparatus is simple in construction move the tow along the conditioning path in intermittent v steps.
  • the present invention provides an apparatus for annealing tow of filamentary material in an intermittent manner which generally includes a conditioning chamber having extensible ingress and egress ends on either side thereof. tensible ends and are adjustable from a normal tow release position to a gripping position. Means are provided to reciprocate these feeding means and to actuate them to gripping position in timed steps so that the tow is gripped and pulled through the chamber in the first stage of the moving cycle, whereupon the feeding means are released to allow movement of the feeding means in the opposite direction of reciprocation. The feeding means are then again actuated to gripping position and a new portion of tow moves with them in the first mentioned direction.
