Abstract (en)
A degumming device in which a silk fabric can be suspended easily and can be degummed uniformly. Radial arms (26) are provided in a cylindrical degumming kier (11). A silk fabric is suspended spirally from the arms by attaching its top edge to hooks provided on the arms. In this state, a gap is present between the adjacent layers of the spirally suspended silk fabric. Since degumming solution can smoothly flow through the gap, the silk fabric can be degummed uniformly. While degumming, the arms are gradually swung upwards so that the distances between the adjacent arms narrow gradually. With this arrangement, the top edge of the silk fabric is allowed to shrink at the same rate as its bottom edge. <IMAGE>
