Description

[Detailed Description of the Invention] This invention relates to a method for batchwise liquid flow treatment of various types of fabrics for dyeing, scouring, etc. The purpose of this invention is to ensure that the fabrics are in a relaxed state so that they can be processed effectively. It is an object of the present invention to provide a method capable of liquid flow processing.

Next, an example of the apparatus used to carry out the method of the present invention and the method of liquid jet treatment of fabric using this apparatus will be explained according to the drawings. A storage tank 2 is formed to store the dye liquid at the lower right side of the figure, and 2 is a reel that is removably hung horizontally close to the dye liquid surface above the storage tank 1, and is driven by a motor (not shown). The fabric C, which is rotated counterclockwise and joined in an endless manner and floats near the dye surface in the storage tank 1, is pulled up by the reel 2.

Reference numeral 3 denotes a distribution duct which is inclined downwardly at a gentle slope toward the passing direction of the fabric C with respect to the left side of the reel 2 in the figure, and the inlet portion 3a at the upper end thereof faces the upper end of the reel 2. At the same time, the bottom surface thereof has convex portions 4 to 4 having a substantially convex arc shape in longitudinal section and recesses 5 to 5 having a substantially concave arc shape in longitudinal section.
A gentle wave-shaped guide cloth surface 3d is formed in which the guide cloth surfaces 3d and 3c are alternately connected along the bottom 3C of the circulation duct 3.

Reference numeral 6.6 denotes injection pipes installed horizontally near the upper and lower ends of the entrance section 3a of the distribution duct 30 in order to flow the dye liquor into the distribution duct 3 from the upper and lower parts of the entrance section 3a of the distribution duct 30, respectively. Outflow holes 6a, 6a are provided opposite to each other on the upper and lower surfaces, and the dye liquor that has flowed into the inlet portion 3a is rectified by the convex portion 4 and the concave portion 5 of the guiding cloth surface 3d while flowing inside the distribution duct 3 to the outlet portion 3b. It naturally flows down at a gentle slope along the guiding surface 3dK toward
The fabric C passes along the liquid flow on the guiding fabric surface 3d in a wave-like manner.

Reference numeral 7 denotes a folded duct that communicates with the outlet 3b of the distribution duct 3, and is formed into a substantially horizontal U-shape with approximately the same cross-sectional area. It is immersed in liquid and passes through it in a U-turn in a folded state.

Reference numeral 15 denotes a guide duct provided to communicate the folded duct 7 and the storage tank 1. The guide duct 15 is formed so that its cross-sectional area gradually increases toward the storage tank 1 side. A guide surface 15a is formed with a gentle upward slope toward the direction, and the fabric C sent out from inside the folded duct γ gradually recovers from the folded state in the guide duct 15 and expands in volume before being transferred to the storage tank 1. At the same time, it floats toward the dye liquor level in the storage tank 1 while maintaining an aligned state while rubbing against the guide surface 15a, and is fed into the storage tank 1 and floats inside the machine. The circulation of the fabric C is repeated.

8 is a pump, and a drainage tank 9 is provided below the storage tank 1.
The dye liquor sucked into the interior through the filter 10 is transferred to the pipe 1.
1 and the heat exchanger 12 to the injection pipes 6, and a folded duct 7 is provided in the guide duct 15.
A liquid flow is generated that flows from the side to the storage tank 1 side.

Note that when a plurality of fabrics C are processed at the same time, similar devices are arranged in parallel in the width direction.

Next, the operation and effects of the embodiment having the above configuration will be explained.

First, when the fabric C pulled up from the storage tank 1 passes through the distribution duct 3, it is rectified by the gently wave-shaped guiding cloth surface 3d, and overflows onto the guiding cloth surface 3d along with a liquid flow that naturally flows down on a gentle slope. Because the fabric C moves in a wave-like manner, the convex portions 4 and concave portions 5 give the fabric C a kneading effect and a relaxing effect. As a result of effective contact with the material, the level dyeing property is significantly improved, the bath ratio is reduced and the dyeing time is shortened, and the occurrence of fuzzing, deterioration of hand, tangles, creases, etc. of the fabric C is suppressed. can improve the finishing quality.

In addition, the fabric C smoothly passes through the folded duct γ while immersed in the dye liquid and folded, and the fabric C passes through the guide duct 15 and enters the storage tank 1 from the folded duct 7. During the transition, the folded state of the fabric C gradually recovers due to the shape of the guide duct 15 that widens at the end, the gentle slope of the guide surface 15a, the liquid flow from the folded duct 7 side toward the storage tank 1 side, etc., and the folded state of the fabric C gradually recovers. To inflate the fabric C to ensure a relaxed state and an aligned state to float the fabric C, and to reliably suppress the occurrence of creases and tangles during circulation to prevent poor dyed finish. Can be done.

That is, in the present invention, an endlessly joined fabric C is pulled up from the liquid in a storage tank 1 below the reel 2 by a reel 2 that is reversibly hung horizontally in the machine, and then is pulled up to the upper end of the reel 2. The cloth C is fed into a distribution duct 3 which is inclined downward at a gentle slope in the direction of passage of the cloth C with the inlet portion 3a opened facing each other as the upper end. , along the guiding cloth surface 3d formed in a gentle wave shape by alternately connecting convex portions 4 and concave portions 5, each of which has a substantially arc-shaped longitudinal section, with respect to the bottom surface of the circulation duct 3, and the inlet portion 3a. The flow flows from the guiding cloth surface 3d and is rectified by the guiding cloth surface 3d.
The fabric C is passed in a wave pattern along with the liquid flow flowing down at a gentle slope over d, and then the fabric C is immersed in the liquid in a folded state through a folded duct γ having a substantially horizontal U-shape connected to the outlet 3b of the distribution duct 3. The fabric C is passed through in a U-turn while being immersed, and the fabric C is formed so that its cross-sectional area gradually increases toward the storage tank 1 side in order to connect the folded duct 7 and the storage tank 1. The guide surface 15a is made to rub against the inside of the guide duct 15, which has a guide surface 15a on the upper wall surface that slopes upward at a gentle slope toward the storage tank 1 so as to float upward toward the liquid level in the tank 1. By feeding the fabric into the storage tank 1 and circulating it inside the machine, it is possible to impart a relaxing effect and a kneading effect to the fabric, thereby increasing the effect of contact with the liquid flow, and also to ensure a relaxed state and circulate it inside the machine. This invention is extremely excellent as a liquid flow treatment method for fabrics, as it allows various treatments to be carried out uniformly and in a short time on fabrics, and improves the finished feel.

Note that the liquid flow treatment of the present invention can be applied to washing, scouring, bleaching, resin processing, etc. in addition to the dyeing processing shown in the above embodiments.
