Definitions

  • This invention relates to a method and a device for degumming a silk fabric.
  • a method and device for degumming a fabric in a degumming kier as described in the first part of claims 1 and 3 is known from US-A-3753358 in which the silk fabric is hung in a spiral pattern as viewed from top so that its width extends vertically.
  • a device comprising a degumming kier, a supporting rod arranged vertically along the central axis of said degumming kier and a plurality of arms extending radially from said supporting rod at a predetermined height, each of said arms being provided with hooks arranged in a longitudinal direction.
  • GB-A-1081479 and FR-A-2228020 disclose similar fabric treatments.
  • Fig. 10 illustrates another conventional method of degumming silk in which silk fabrics a folded in a longitudinal direction are hung in a rectangular degumming kier 1.
  • a degumming solution b is fed into the degumming kier 1 from its top, discharged from its bottom and resupplied into the kier from its top, so that the solution is circulated through the degumming kier 1.
  • the degumming solution b flows downwards in the degumming kier, whereas the silk fabrics a are folded in a longitudinal direction.
  • the degumming solution does not flow uniformly into the inner layers of the folded silk fabrics, so that they cannot be degummed uniformly over the entire length thereof.
  • An object of the present invention is to provide a degumming method and device which permits a uniform circulation of the degumming solution throughout the degumming kier, while facilitating the work for fixing the fabric in the kier.
  • Another object is to provide a degumming method and device which improves the workability.
  • the top edge of the silk fabric are fixed at a plurality of points arranged in a spiral pattern as viewed from top so as to rise gradually outwardly from the center of the spiral pattern.
  • the spiral shape of the silk fabric should be such that the inclination of the plane extending from the center of spiral pattern to its outer periphery increases gradually.
  • the device for degumming a silk fabric may comprise a degumming kier, a supporting rod arranged vertically along the central axis of the degumming kier, and a plurality of arms extending radially from the supporting rod at a predetermined height, each of the arms being provided with hooks arranged in a row in its longitudinal direction.
  • the arms should be inclined upwardly outwards. Further, such a device should further comprise a vertically movable sleeve concentrically threaded around the supporting rod, the arms extending from the sleeve.
  • the arms should be designed so as to be pivotable up and down about their inner ends.
  • the device should be further provided with a sleeve vertically movably mounted on the upper part of the supporting rod so as to be driven from outside, and coupling levers connecting the sleeve to the arms so that the arms can be pivoted by the vertical movement of the sleeve through the coupling levers.
  • the degumming kier should preferably be shaped cylindrically.
  • Gaps between the adjacent layers of the spirally wound silk fabric extend through the entire height of the fabric.
  • the degumming solution can flow freely through these gaps. Since such gaps are present over the entire area in the degumming kier, the degumming solution is circulated uniformly over the entire area in the degumming kier.
  • the hooks for hanging the silk fabric are arranged so that outer ones are located higher than inner ones, an operator can hang the fabric on inner hooks without being hindered by outer ones. Even though the hooks are arranged upwardly outwards, the fabric can be fixed at the same level by gradually lowering the entire arms.
  • the silk fabric may shrink while degumming. But since it is fixed to the hooks along the top edge, only the portion near the bottom edge shrinks markedly while its top portion scarcely shrinks, so that the fabric might be distorted in the longitudinal direction.
  • the top edge of the fabric should be moved in such a way that the inclination of the plane defined by the top edge of the fabric increases gradually from its center to outer periphery. With this arrangement, the distances between the circumferentially adjacent fixing points can be reduced gradually. This can compensate for any shrinkage of the fabric. Thus, the fabric is kept free from distortion.
  • the spirally wound silk fabric has a cylindrical outer configuration.
  • the degumming kier should also have a cylindrical shape because by doing so, a degumming solution can be circulated smoothly while keeping its amount to a minimum.
  • the degumming solution can be distributed uniformly throughout the degumming kier, so that the silk fabric can be degummed uniformly. Also, the silk fabric can be hung easily.
  • a supporting rod 12 extends vertically along the axis of a cylindrical degumming kier 11.
  • the kier has a lid 13 driven by a cylinder 14 between open and closed positions and is filled with a degumming solution b .
  • the solution is discharged from the bottom of the kier 11 and sucked up by a pump P through a strainer 15, fed through a supply pipe 16 and sprayed back into the kier 11 through a perforated tray 17. The solution is thus circulated.
  • a rotary sleeve 18 is rotatably mounted on the supporting rod 12 through a thrust bearing 19 and metals 20 (Fig. 2).
  • a guide cylinder 21 is secured by screws to the top end of the rotary sleeve 18.
  • a square-threaded hollow shaft 22 is inserted in the top end of the supporting rod 12 and coupled thereto by a key 23 (Fig. 3).
  • a vertically movable hollow shaft (referred to as “sleeve” in the claims) 24 is coaxially threaded into the square-threaded shaft 22.
  • the hollow shaft 24 can be moved up and down along the square-threaded hollow shaft 22 (supporting rod 12) by rotating it about its own axis. Its movement is guided by a guide lever 25 provided at the bottom end of the hollow shaft 24 and slidably fitted in a vertical guide groove 21a formed in the guide cylinder 21 (Fig. 4).
  • the vertically movable hollow shaft 24 and the rotary sleeve 18 are not rotatable relative to each other.
  • Arms 26 extend radially outwardly from the mid-portion of the hollow shaft 24 so as to be arranged at equal intervals (Fig. 4).
  • the arms 26 are pivotable about their inner ends.
  • the number of arms 26 is determined according to how a silk fabric a is suspended.
  • Hooks 27 are provided on each arm 26 at equal intervals in its longitudinal direction.
  • a guide cylinder 28 is secured to the vertically movable hollow shaft 24 through a boss 28' (Fig. 2).
  • a sleeve 29 is vertically movably threaded on the hollow shaft 24 at its portion surrounded by the guide cylinder 28.
  • a ring 30 is rotatably fitted on the sleeve 29.
  • Support plates 31 protrude from the ring 30 outwardly through grooves 28a formed in the guide cylinder 28.
  • An annular frame 32 is secured to the free ends of the support plates 31 (Fig. 4).
  • the annular frame 32 carries rollers 33 on its underside at portions opposite the arms 26.
  • the rollers 33 are received in respective guide frames 34 of the arms 26 (Fig. 6).
  • the rollers move in the guide frames 34, so that the arms 26 pivot up and down.
  • the lid 13 has in the center an opening in which is fitted a packing 37 (see Fig. 1).
  • a handle shaft 35 By inserting a handle shaft 35, the opening can be liquid-tightly sealed.
  • the handle shaft 35 has a square tip which is inserted in a square hole formed in the top end face of the sleeve 29. By turning the handle shaft 35 in this state, the sleeve 29 can be moved up and down with respect to the vertically movable hollow shaft 24.
  • a suspension mechanism including the supporting rod 12 is taken out of the degumming kier 11 and placed on the ground by means of a crane.
  • the vertically movable hollow shaft 24 is raised until the arms 26 reach their highest position.
  • silk fabric a is hitched, from inside to outside, to the hooks 27 on the arms 26 so that it is hung from the hooks in a spiral pattern as shown in Fig. 9.
  • the silk fabric can be attached to the inner hooks of each arm without being hindered by the outer ones of the same arm.
  • the hollow shaft 24 can be rotated to lower it. By doing so, one can attach the fabric at the same height. Thus, the operator can do his work easily.
  • the suspension mechanism is brought back into the degumming kier 11 so that the supporting rod 12 is disposed on the center axis as shown in Fig. 1.
  • the lid 13 is then closed.
  • the handle shaft 35 is pulled out as shown by chain line in Fig. 1 to prevent its tip from abutting the sleeve 29.
  • the handle shaft 35 is pushed in until its tip is received in the square hole 29a formed in the sleeve 29.
  • degumming solution b is supplied into the degumming kier 11 and circulated through the kier to degum the silk fabric.
  • the handle shaft 35 is turned gradually to move the sleeve 29 upwards and thus to pivot the arms 26 upwards.
  • the plane containing the top edge of the silk fabric becomes gradually steep (Fig. 9).
  • the distances between the circumferentially adjacent hooks decrease gradually.
  • the ascending speed of the sleeve 29 varies according to the kind of silk fabric and may be determined through actual operations or experiments.
  • the handle shaft 35 may be driven by a motor. In this case, the arms 26 can be moved automatically by controlling the motor speed.
  • the suspension mechanism is taken out of the kier 11 together with the degummed silk fabric and the silk fabric is detached from the hooks 27.
  • the vertically movable hollow shaft 24 is turned in such a direction that it ascends. By doing so, the fabric can be detached from the hooks at the same height.
  • the arms 26 come to the position shown by chain lines in Fig. 2.
  • the mechanism for pivoting the arms 26 may comprise the sleeve 29 and coupling levers 36 coupled to the sleeve 29 and the respective arms 26 through pins.
  • a liquid-tight door may be provided on one side of the degumming kier 11. This door allows access to the interior of the kier, so that it is not necessary to take the suspension mechanism out of the kier in order to hang a silk fabric.
