Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an untwisting and embossment processing device in a liquid flow processing device for textile products such as fabrics.

Conventional technology In general, when untwisting and embossing highly twisted yarn fabrics, etc., unlike in the case of relaxing treatment of textured yarn knitted fabrics, etc., the workpiece is placed in an appropriate tension or no tension state and in an appropriate warm water. It is necessary to process while applying strong forced vibration or shock.

Conventional untwisting and graining processing equipment for highly twisted textiles, etc., involves placing the fabric to be processed into a rotating drum,
There is a rotary drum washer that performs processing by rotating this drum forward and backward in high-temperature liquid. This type of washer can apply a strong impact or counter-beating action to the fabric, so it has a good untwisting effect, and although various improvements have been made, its basic structure has remained unchanged for several decades. It is still widely used today.

Furthermore, some recent liquid flow processing apparatuses include a collision plate or a baffle plate attached to the exit side of a transfer passage or the inlet side of a retention tank. Examples include Utility Model Publication No. 44-29741 and Japanese Patent Application Laid-open No. 58-60056,
Further examples include JP-A No. 62-243863.

Problems to be Solved by the Invention However, when performing the untwisting and graining process using a washer as described above, the long fabric is fed in a spiral shape, so it is necessary to prevent the rolled fabric from unraveling and tangling during the process. In order to do this, many workers have to perform a selvage stitching operation called "andon stitching" by hand.

In addition, in a device equipped with a collision plate or a baffle plate, the fabric being circulated and transported collides with the collision plate together with the processing liquid, but this collision occurs while changing direction from the narrow transfer passage to the wide retention tank. This is to organize the fabrics so that they can be transferred smoothly, and although it may give a relaxing effect to ordinary fabrics,
It was not possible to perform untwisting and graining treatment on highly twisted yarn fabrics.

In other words, even if the fabric hits the collision plate after coming out of the treatment liquid spraying section through a long transfer path, the fabric speed will be significantly reduced and the necessary hanging or impact action will be applied to the fabric. This is because it is not possible.

On the other hand, in Japanese Patent Application Laid-Open No. 62-243863, a collision part is provided at a position close to the outlet side of the treatment liquid injection part, where the textile product collides with the liquid flow. However, even with this device, there are cases where sufficient untwisting and embossment effects cannot be exerted on textile products such as dioset using polyester as the dyed material due to insufficient striking or impact force.

The object of the present invention is to overcome the above-mentioned difficulties and to provide an apparatus that can be expected to be sufficiently effective in terms of texture and appearance when untwisting and embossing highly twisted yarn fabrics.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention has a method in which textile products connected in a loop are loaded into an annular processing passage in which a retention tank and a transfer passage are connected at both ends, and a textile product is ejected from a processing liquid injection part. In a liquid flow processing apparatus that performs dyeing or other processing while being circulated by a liquid flow, a preparation having an inclination angle with respect to the flow path axis in a transfer passage close to the outlet side of the treatment liquid injection part. By providing at least one path bent at a substantially right angle through the bending path, the textile product that is continuous with the liquid flow is delivered along the flow path after colliding with the curved wall surface. This device is used for untwisting and embossing in a jet dyeing machine for textile products.

Function: In the present invention, at least one passage is provided at a position close to the processing liquid injection part in the transfer passage connected to the processing liquid injection part, which is bent approximately at right angles to the flow path through a preparatory bending passage. Therefore, immediately after exiting the treatment liquid spraying section along with the jet flow, the textile product directly hits the curved wall surface, which is a passage perpendicular to the flow path, at the stage where the cloth velocity is the highest.

Therefore, it is possible to apply a strong beating action at a position where the cloth speed is not reduced due to piping resistance in the transfer passage, and it has become possible to perform untwisting and embossment processing that is equal to or better than that of conventional washers. Moreover, since the processing mechanism is a circulation transfer using a liquid flow, there is no need for ear-stitching work, making it possible to significantly streamline the work.

Embodiment The drawings show one embodiment of the device of the present invention, and the main parts are shown enlarged. 1 is a retention tank,
The treatment liquid is retained, and the long fiber products such as fabrics connected in a loop shape are moved in a meandering manner, and are temporarily retained therein. Reference numeral 2 denotes a transfer passage, which is connected to the retention tank 1 at both ends to form an annular processing passage. Reference numeral 3 denotes a processing liquid injection section, which is connected to the outlet section of the retention tank 1. 4 represents a treatment liquid, and 5 represents a fabric. 6 is a reel. The fabric 5 is sent from the retention tank 1 via the reel 6 into the transfer passage 2 by the jet flow of the treatment liquid spraying section 3, and is circulated so that it is sent back into the retention tank 1 from the other end of the retention tank 1. During this time, the fabric etc. is subjected to dyeing and other treatments using the treatment liquid. Reference numeral 7 designates a processing liquid circulation path in which processing liquid is sucked from the retention tank 1 through at least one regulating port through a suction pipe, passes through a pump 8 and a heat exchanger 9, and is injected from the processing liquid injection unit 3 into the transfer passage 2. It's getting old.

In the enlarged cross-sectional view of FIG. 2, reference numeral 10 denotes a curved wall surface, which forms a passage bent approximately at right angles to the flow path. This bent wall surface 10 is inclined at an inclination angle θA with respect to the jet flow axis Y from the processing liquid injection part 3, and is also perpendicular to the transfer passage axis A with an inclination angle θB.
A transport passage axis B is formed which is bent in the direction of the arrow. As the curved wall surface 10, a flat plate is mainly used, but a plate with holes like a nest or a corrugated plate may also be used. Inclination angle θA is inclination angle θB
It is a preparatory bending road to make it right-angled.
Since θB is bent at a right angle, the fabric etc. transported with the jet flow hits this wall surface with a strong force, giving a driving action to the fabric etc.

By bending the transfer passage 2 and providing the bent wall surface 10 as in this embodiment, a strong impact effect was generated, and the following effects were obtained.

The untwisting effect (referred to as relaxation) is expressed as the sum of the number of warp yarns and the number of horizontal yarns in a certain range. If this value is between 80 and 90, it means that the relaxation effect has increased.

In this example, the relaxing effect obtained a value of 84 to 86 under the following conditions.

Effects of the invention Since the invention has the above-mentioned configuration, immediately after the fabric, etc. is introduced into the transfer passage along with the jet flow from the treatment liquid jetting part, it passes through the preparatory bending path and hits the curved wall surface which is formed at an approximately right angle. As a result, the striking action of the collision part is applied at the earliest stage of the fabric speed, realizing a longitudinal shrinkage effect and eliminating rope wrinkles near the edges. The untwisted texture is reliably applied to the fabric, giving it a soft texture.
The eyes improved, and the effects of dyeing and other textile processing became even better.
