Definitions

  • the object of the present invention is a process for the manufacture of potentially crimped filament yarns of synthetic linear high polymers such as, for example, polyethylene terephthalate, poly-e-caprolactam, polyhexamethylene-diamine adipate.
  • synthetic linear high polymers such as, for example, polyethylene terephthalate, poly-e-caprolactam, polyhexamethylene-diamine adipate.
  • crimped filament yarns of linear polymers are obtained by heating a stretched filament yarn to a temperature of 30 to C. below the melting point, stretching the filament yarn beyond its yield point, cooling the filament yarn and deviating it at a sharp edge in such a manner that the threadine of the filament yarn forms an acute angle at the deviating edge, and then allowing the filament yarn to shrink.
  • This process is carried out with the stretched filament yarn and constitutes, therefore, an aftertreatment .or a finishing operation.
  • the filament yarn touches the small, highly heated surface over a distance of at least 0.3 mm. and at most 5 mm.
  • the heated surface can, for example, be an electrically heated resistance wire having a diameter of, for example, 2 mm.
  • the time of contact is very short, and it has proved to be useful when said time of contact is within the range of 0.00008 to 0.01 second.
  • the yarn is not heated thoroughly but only on one side due to the fact that its filaments are only heated on that side on which they have touched the heated surface for a short period of time.
  • snubbing pin or a snub'bing roller which may be heated or not heated, with the purpose of localizing the stretch point in the filament yam during the stretching process.
  • the small, highly heated surface which the filament yam touches Whhe being deviated shall then, according to the invention, be arranged between the snu bing device and the drawing roller.
  • the process of the invention constitutes a considerable advance in the art inasmuch as it can be applied with little expenditure to the stretching machines customarily used for the manufacture of filament yarns which are mers exhibiting a good crimp effect in a simple and,
  • the filament yarns After having undergone the treatment according to the invention, the filament yarns first have a smooth appearance. Crimping only appears when the filament yarns are shrunk, for example, by heating them by air from 100 to 240 C., by water from to C., but also when brought into contact with a plate or roller having a temperature ranging from 100 to 240 C.
  • woven or knitted goods from the-still smooth filament yarns treated according to the invention, said woven or knitted goods being allowed to shrink by subjecting them to a treatment with hot air, hot Water, as mentioned above, or with a suitable solvent such as, for example, ethylene chloride or acetone, in the course of which treatment the filament yarns shrink and crimp thus imparting to the woven or knitted fabric a high degree of elasticity.
  • a suitable solvent such as, for example, ethylene chloride or acetone
  • FIGURE illustrates a form of apparatus for carrying out the process of the invention.
  • Example 1 A meltspun undrawn multifilarnent yarn 1 consisting of 25 single filaments of polyethylene terephthalate was taken off the spinning bobbin by a feed roller 2 and a separating roller 3 at a speed of m./minute. In order to localize the stretch point, the yarn l was passed once around a stationary snubbing rod 4 heated at 90 C. and having a diameter of 60 mm. The yarn was heated on one side by passing it over a resistance wire 5 electrically heated at 500 C.
  • Example 2 A spun yarn of polyethylene terephthalate of 660 deniers having 50 individual filaments was taken off the spinning bobbin by an unheated feed roller, around which the yarn was passed in several wraps, and conducted, also in several wraps, over a s-nubbing roller heated at 105 C. The yarn was then passed over a roller, installed in a water bath and driven by the friction of the yarn, and subsequently at an angle of 155 over a metal wire heated at about 840 C. to the drawing roller driven at a speed 4.4 times higher than that of the feed roller. In the course of this operation, the yarn was stretched down to deniers. When the yarn was then- Patented Dec.
  • a meltspun yarn of poly-e-caprolactam of 180 deniers having 9 individual filaments was taken off the spinning bobbin by an unheated roller around which the yarn was passed in several wraps, and was stretched between an unheated snubbing pin, around which the yarn Was passed at an angle of about 180, and a dnawing roller driven at a peripheral speed being four times as high as that of the feed roller at a draw-cit speed of 400- rnJrninute into a yarn of 45 deniers.
  • the yarn is then passed at an angle of 140 over a Wire installed before the drawing roller and heated at 570 C.
  • the yarn was then wound on a bobbin and processed into warp-knitted goods which were allowed to shrink in the relaxed condition at 180 C. Due to the yarn getting crimped, the goods had an especially soft and full handle.
  • a continuous process for making intently crimped filament yarn of synthetic, thermoplastic, linear high polymers, said yarns being adaptable to crimping by subsequent shrinking which process comprises drawing unstretched filament yarn by stretching said yarn to two to eight times its original length While heating one side thereof for 0.00003 to 0.01 second by passing said yarn at a speed of more than 100 meters/minute over a small surface heated at a temperature between 300 C. and
  • the yarn touching said heated surface only over a distance of 0 .3 millimeter to 5 millimeters and being changed in direction at the heated surface such that the yarn approaching the heated surface forms an obtuse angle of between and with the yarn leaving the heated surface.
