Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention injects a pressurized fluid toward a yarn traveling axially at a high speed in a tubular yarn treatment region and utilizes the turbulent flow of the fluid to entangle the yarn. The present invention relates to a yarn entanglement processing apparatus (also referred to as an entanglement processing nozzle) for imparting a stable focusing property or bulkiness to a yarn and a manufacturing method thereof.

2. Description of the Related Art In a yarn entanglement processing apparatus, in order to impart a stable entanglement to the yarn, the portion in contact with the yarn running at high speed is made of a material having high abrasion resistance. There is a need. For this reason, the tubular yarn treatment region and the yarn treatment region portion having an injection nozzle for injecting a pressurized fluid to the yarn treatment region have been made of a material having high abrasion resistance such as ceramics. However, because of the difficulty of processing this material and the economical reason, the other portion, that is, the fluid supply portion for supplying the pressurized fluid to the injection nozzle is made of a separate material such as metal, and the two are joined together. Often used. JP-A-58-65028, JP-A-58-65029
The entanglement processing apparatus of this type is shown in Japanese Patent Publication No. 52-128751 and the drawings.

[0003]

In the entanglement processing apparatus, the state of the flow of the fluid to be injected has a great influence on the entanglement effect. To give the yarn an excellent and uniform entanglement effect,
The object is to reproduce the same flow of the fluid ejected in the yarn processing region between different devices without disturbing the flow of the fluid in the ejection nozzle, and maintain an excellent confounding effect. for that purpose,
It is conventionally known that the axis of the injection nozzle of the processing region member and the axis of the fluid pipe of the fluid supply member must be aligned. However, as described above, the processing region member is made of ceramic or the like, whereas the fluid supply member is made of metal or the like and can be manufactured more accurately than ceramic or the like. Therefore, even if the axial center of the injection nozzle and the axial center of the fluid pipe are made to coincide with each other in design, the actual apparatus does not necessarily have the same axial center due to differences in accuracy and materials. Usually, a pipe expansion portion is provided at the joint end portion of the fluid pipe of the fluid supply member so that the flow is not blocked due to the positional deviation from the injection nozzle. However, although there is no clogging, there is a problem in that the flow in the nozzle differs from device to device due to the disagreement of the axes, and the confounding effect becomes uneven, resulting in poor reproducibility. For this reason, conventionally, when joining the processing region member and the fluid supply member to all the devices, centering of both axes and inspection thereof have been required. This work was necessary not only when assembling the newly created entanglement processing apparatus, but also after disassembly and cleaning. The present invention solves this problem, and provides an entanglement processing apparatus that has an excellent entanglement effect and can be easily produced and assembled with good reproducibility, and a method for producing the same.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The yarn entanglement processing apparatus and the manufacturing method thereof according to the present invention will be specifically described with reference to the drawings. FIG. 1 is a schematic cross-sectional view showing an example of the yarn entanglement processing apparatus of the present invention, FIG. 2 is a vertical cross-sectional view taken along the line AA ′ of FIG. 1, and FIGS. 3 and 4 show the yarn of the present invention. It is an outline sectional view showing an example of a processing field member of a confounding processing device, and an outline sectional view showing an example of a processing device.

The yarn entanglement processing apparatus according to the present invention comprises two members, namely, a cylindrical yarn processing region 3 for axially traveling the yarn to perform entanglement processing and a pressurized fluid in the yarn processing region. The processing area member 1 (1a and 1b) having at least one jet nozzle 4 for jetting the liquid and the fluid supply member 2 having a flow path for supplying the pressurized fluid to the jet nozzle 4 are joined together. It is configured. The yarn processing area 3 is
The axis is formed in a tubular shape orthogonal to the drawing, and the entangled yarn runs in the axial direction at high speed. The pressurized fluid for entanglement of the yarns is jetted into the yarn processing region 3 from the flow path 5 through the jet nozzle 4. The cross-sectional shape of the yarn processing region 3 is usually circular, but it may be, for example, a missing circle as shown in FIG. 3 or another shape.

To insert the yarn into the yarn treatment area 3,
A slit-shaped yarn insertion port 7 is provided on the peripheral wall in parallel with the generatrix of the yarn processing region and the center line passes through the center of the opening of any one injection nozzle 4. Further, a yarn introduction path 6 having a slit-shaped cross section parallel to the generatrix is provided between the outer peripheral surface 8 of the processing region member facing the outside of the entanglement processing device and the yarn insertion port 7. The yarn introducing passage 6 is first guided from the outer peripheral surface 8 to an intermediate portion of the jet nozzle 4, and then the yarn introducing passage 6
Is connected to the yarn introducing port 7 with its center plane aligned with the axis of the jet nozzle 4. The reason why both are matched is that the running yarns do not fly out of the yarn processing area 3. The outer peripheral surface 8 and the injection nozzle 4 are easy to manufacture.
In many cases, the yarn introduction path 6 is placed on a plane orthogonal to the axis of the yarn and the axis of the yarn. The number and position of the injection nozzles are not particularly limited, and only one 4a may be provided, or 4a and 4b may be provided so as to face each other.

Further, an important feature of the entanglement processing apparatus of the present invention is that the processing area member 1 is composed of two members 1a and 1b.
It is divided into two parts, manufactured separately and accurately, and then joined together to form one processing region member 1 integrally. The integral construction means that after the members 1a and 1b are manufactured separately, they are joined together, and thereafter, unless otherwise specified, they are treated as one member without being divided. The dividing surface 9 includes the outer peripheral surface 8 and the injection nozzle 4
This is a plane that intersects the axis of (1) and is parallel to the axis of the yarn processing region 3, that is, a plane perpendicular to the drawing. The dividing surface 9 is preferably orthogonal to the axis of the jet nozzle 4a and passes through the yarn introducing passage 6 between the outer peripheral surface 8 and the axis of the jet nozzle 4a. Preferably. There is an advantage that the members 1a and 1b can be manufactured easily and accurately. In this case, the split surface 9 passes through the yarn introducing path 6 and intersects the axis of the injection nozzle 4a. The members 1a and 1b need to be joined so that the axis of the injection nozzle 4a does not shift. For this positioning, a positioning pin or fitting may be used. The diameters of the injection nozzles 4a and 4b provided on the members 1a and 1b do not necessarily have to match, but the axes must match. Usually, an adhesive is used for the joining, but other known fixing methods may be adopted. The reason why the processing area member 1 is divided in this manner is to efficiently manufacture an entanglement processing apparatus that forms a stable fluid flow without requiring centering work.

EXAMPLE In order to clarify the effect of the yarn entanglement processing apparatus of the present invention, an example will be described. The yarn entanglement processing apparatus of the present invention of the same type as that shown in FIG.
0 pieces were manufactured and the product was inspected. The divided surfaces of the processing area member were fixed with an adhesive. On the other hand, although the dimensions are the same as those shown in FIG. 5, they are different from each other in that they are manufactured without dividing the processing region member and the yarn introducing passage is provided on the surface where the processing region member and the fluid supply member are joined. Twenty conventional confounding processing devices similar to the above were manufactured and their products were inspected. Both of the treatment areas had a cylindrical shape with a cross-sectional diameter of 2 mm and a length of 10 mm, and the injection nozzle had a hole diameter of 1 mm. In the inspection, the degree of entanglement was determined by the chemical fiber filament yarn test method (JIS L1031), and 20 or less was rejected. Using 36 filaments and polyester yarn with total fineness of 75 denier, 1
Entanglement processing was performed at a speed of 000 m / min. As a result, in the entanglement processing apparatus of the present invention, all 20 pieces passed the inspection, but in the conventional one, in two of them, the yarn is caught in the yarn insertion port and the yarn breaks, and the entanglement degree of 6 Was 20 or less, and in the end, 12 were acceptable products.

[0011]

By using the yarn entanglement processing apparatus and the manufacturing method thereof according to the present invention, when the processing area member and the fluid supply member are joined by dividing the processing area member into two members. Moreover, it is not necessary to center the injection nozzle and the flow path of the pressurized fluid. The two members forming the processing region member require centering of the injection nozzle, but they are both manufactured with high accuracy, and can be easily and efficiently joined by providing a pin for positioning in advance. The flow of the fluid in the injection nozzle provided in the processing region member is stable and free of turbulence, and there is no unevenness between the confounding processing devices. Even when the processing area member and the fluid supply member are joined after disassembly and cleaning, they can be easily joined without centering work and the entanglement process can be reproduced without change.
