Description of the Related Art In general, as a continuous dyeing apparatus for fabrics, a padder type continuous dyeing apparatus using a so-called Pad-Squeeze-Steam Process has been widely used. This device has a high labor-saving effect in dyeing a normal planar knitted fabric, and has an effect of enabling high-productivity dyeing processing.However, if this device is applied to a tubular knitted fabric as it is, Unlike the case of flat fabric dyeing, when squeezed by a squeezing roller, the tubular knitted fabric is folded into a double flat folded state. The degree of squeezing is different from the other flat portions in the ear portions at both ends of the double flat folded state in the folded shape. As a result, if the pressing pressure is too small, as shown in FIG. 4, the squeezing is poor near the ears at both ends, the amount of dye solution held in this portion increases, and if the pressing pressure is too high, As shown in Fig. 5, the diaphragm is strong near the ears at both ends,
The amount of dye liquor retained in this part was reduced, often causing squeezing spots of the dye liquor.

It is virtually impossible, and there is no fundamental solution other than finding and eliminating other effective measures. The implementation of this measure is a basic problem to be solved in the dyeing of a tubular knitted fabric by a padder type continuous dyeing device, and the so-called frosting based on water droplets due to condensation on the surface of the tubular knitted fabric in the dyeing device. Due to the appearance of the so-called marbling-like dyeing state, the solution of the problem that deep and high-quality dyeing cannot be performed has also been strongly demanded.

ークが発現するのである。As described above, when this continuous dyeing apparatus is carried out with a conventional cylindrical body pressed into a double flat body, the drawing pressure of the pressing rollers 2a, 2a is small as shown in FIG. In the bent portions (edges) (shaded portions) at both ends of the double plane body pressed by the tubular knitted fabric, minute voids are formed inside, and a large amount of dyeing liquid is contained in this portion. When the dyeing fixation is carried out in the steamer 6 in this state, a dyeing concentration corresponding to the amount of the dyeing solution is developed. Are so-called edge marks, which are dyed in dark colors and stripes.

適用した際のエッジマーク出現の発生因と実態である。On the other hand, if the drawing pressure is too high, on the other hand, as shown in FIG. 5, the cylindrical knitted fabric is locally overpressed at both ends of the double flat body pressed by the pressing rollers 2a, 2a. , The bent part (edge) at both ends (shaded area)
When the dyeing liquid inclusion amount locally decreases and enters the steamer 6 in this state, and the dyeing and fixing is performed, the vicinity of the bent portion at both ends of the pressed double planar body becomes light-colored and streaked. A light-colored edge mark, which is the opposite of dyeing, appears. This is the cause and the actual state of appearance of edge marks when the conventional continuous dyeing system is applied to a tubular knitted fabric.

れない筒状編織布の連続染色装置を得ることができる。As described in detail above, in the conventional dyeing of tubular knitted fabric by the padder type continuous dyeing device, the endless tubular knitted fabric supplied from the fabric supply device is pressed and folded into a double plane. Introduced to the padder in the state, and applying the squeeze dyeing liquid in the pressed double planar folded state, based on the unevenness of the squeezing effect in the vicinity of the bent portions at both ends of the tubular woven fabric in the pressed double planar folded state Since a stain-containing spot occurs, which causes streaked spots, so-called edge marks, to appear in the dyed product as it is, it is impossible to apply such a high productivity padder type continuous dyeing process. According to the continuous dyeing apparatus of the above, even if the dyeing liquid is applied to the tubular knitted fabric in the state of being folded in a pressed double plane shape, it is spread by the spreading device, so that the tubular knitted fabric has streaky irregularities (edge marks).
C) is not likely to occur, and a continuous dyeing apparatus for tubular knitted fabric, which is not limited to the material and the hue, can be obtained.
