Definitions

  • the stufiing-box type crinkler or crimper is generally satisfactory for processing the heavy-denier tows which can either be cut to the desired staple length and then processed on one of the available staple textile systems (e.g., the cotton system) or utilized directly without prior cutting in one of the systems involving a tow breaker, such as the Turbo Stapler or the Pacific Converter.
  • Each of these orifices communicates with two adjacent, horizontally elongated reservoirs within the respective wall of the crimper, of which one is supplied with the desired finish and is positioned on one side of the horizontal orifice, while the other one supplies a second fluid under pressure and is positioned on the other side of the orifice, so that the aqueous suspension of the finish, which is metered into its reservoir at a constant rate, is delivered into the fiber mass in a uniform manner along the entire width of the crimping chamber and is propelled into the compact bundle of fibers by the second fluid.
  • the second fluid is steam or hot air as normally employed to heat-condition the fibers for crimping.
  • FIGURE 1 is a front elevation of a preferred embodiment
  • FIGURE 2 is a side elevation of the same
  • FIGURE 3 is an enlarged detail representing cross section 13-13 of FIGURE 2.
  • FIGURE 4 is a cross section of a modified form of appaartus, showing an adaptation of this invention to a horizontal type stuifing box.
  • each of said reservoirs communicating with orifice 6, and each of them, including said orifice, extending horizontally for the full width of the Wall in which they are lodged (see dotted lines in FlG. 2).
  • tow is forcibly packed into crimper chamber 2 by,
  • crimper rolls 1 which are driven by a mechanism not shown.
  • One of the crimper rolls 1 is flexibly mounted, as indicated in FIG. 1 of said US. Patent 2,747,233, to permit controlled loading of the tow at the nip of rolls 1.
  • an aqueous suspension of textile finish metered through lines Sby constant delivery pumps (not shown), is projected into the bundle of fiber by a gaseous fluid under pressure admitted through lines 4.
  • the bottom of crimping chamber 2 is closed by clapper 3 which pivots about shaft 8 and is under a controlled degree of loading schematically represented by cantilevered weight 7.
  • the crimping apparatus is disposed horizontally and the reservoirs,shown at 5B and 4B, respectively, run transversely of the horizontal walls (roof and floor) of the rectangular chamber and extend for the full width of said walls. Otherwise, the construction and operation are essentially the same as described with reference to the vertical modification shown in FIGS. 1,
  • a crimping device for synthetic fibers which comprises walls of substantial thickness defining an oblong, essentially rectangular crimping chamber through which the fiber to becrimped moves under compression, means for treating said fiber with a textile finish while it is contained in said chamber, said means comprising a horizontally disposed, elongated, straight edged orifice in the inner face of each of two oppositely facing walls of said chamber, the two orifices facing each other at the same distance from and relatively close to the point at which the fiber enters said crimping chamber, and two adjacent, horizontally elongated reservoir chambers communicating with said orifice within each of said two walls, each of said chambers and said orifice extending for the full width of the Wall in which they are lodged, one of said chambers being positioned on one side of said orifice and being provided with means for feeding textile finish thereinto, and the other of said chambers being positioned on the other side of the orifice and being adapted to receive and pass into the crimping chamber through said orific
  • a crimping device as in claim 1 the walls of said rectangular chamber being disposed in vertical planes, defining a vertical passage for said compressed fiber mass, and said orifices and reservoir chambers being located in each of the two wider walls of said rectangular chamber.
