Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The disclosed technology belongs to the technical field of manufacturing glass nozzles for spinning, in which viscose or the like is extruded to form chemical fibers.

[0002]

2. Description of the Related Art As is well known, the improvement of civic life depends largely on the development of various industries. However, even in the textile industry which greatly supports the civic life, due to various reasons, chemicals are added to natural fibers. Fibers have been replaced, and in the chemical fiber industry, nozzles for extruding high-concentration highly viscous raw materials such as viscose are extremely important. Most of the pores of glass nozzles for glass are circular holes, and spinning is carried out by pressurizing through the circular holes under high pressure. Therefore, the fiber obtained is monotonous with a circular cross section, As a result, the yarn does not have the swelling property and elasticity like that of the conventional one, and as a result, there is a drawback that there is a limit in breathability, water absorption, and lightness.

Therefore, in order to improve the characteristics of the chemical fiber which is caused by the circular cross section, the present applicants have proposed a deformed hole glass nozzle for spinning, which is used to manufacture and use a deformed metal wire (Japanese Patent Publication No. 47-9522). However, as for the nozzle hole for spinning, a very fine hole is formed in one nozzle from several hundred holes to several thousand holes, and in order to form the minute hole into the irregular shape hole, A metal profile wire is indispensable, and in order to produce a fine metal profile wire in order to avoid variations in the diameter of the spun fiber and make it uniform, it is necessary to prepare a die for high-precision profile wire and a high degree of kneading. Manufacturing technology is required, and there is a problem that it takes a lot of time and labor, and as a result, it takes a long time and a high cost to manufacture the deformed hole glass nozzle for spinning, and the number of the manufactured nozzles cannot be increased. was there.

Further, the deformed holes of the glass nozzle for spinning with a single metal deformed wire produced by a die use only a metal deformed wire having a simple shape because an extra fine wire is used for a fine hole, Therefore, the shape of the irregular shaped hole for spinning is limited to a simple shape, and there is a negative point that it cannot respond to the addition of new functions and high functions.

[0005]

In response to this, as shown in FIG. 17, for example, as shown in FIG. 17, metal wires 3'and 3'are spliced in a mutually parallel state to form a hole, and a deformed hole is formed. Although a technique for forming the holes has been devised, the holes are divided from each other by the pressure of the viscose undiluted solution passing through the holes formed by the metal wires 3'and 3 ', so that the nozzle hole bodies are individually separated. However, there is a problem in that the intervals formed in the circular cross section are irregularly close to each other, and as a result, the raw material such as viscose or the like has a circular cross section and is monotonous.

The background of the invention of this application is that the nozzle hole of the glass nozzle is made of a fine diameter to improve the trait of the chemical fiber derived from the nozzle hole main body having a circular cross section based on the above-mentioned prior art. In consideration of the fact that the spun fiber is formed in 1,000 holes, the spun fiber formed has excellent heat retention, breathability, swellability, and weight reduction. By using a deformed wire made of twisted strands, variations in the diameter of the spun fiber can be prevented,
It has been found that it is made uniform.

[0007]

The object of the invention of this application is to solve the problems of the glass nozzle for spinning based on the above-mentioned prior art, and to solve the problem of the irregular nozzle hole for spinning produced by using the twisted metal profile wire. Nozzle holes with excellent various hole cross-sections and hole structures are formed in the glass nozzle to eliminate variations in the diameter of the spun fiber and make it possible to form a set number of nozzle holes with a uniform diameter and a designed interval. It has excellent heat retention and breathability, excellent water absorption, weight reduction, and can be made into spun fibers that have the same texture as natural fibers. It is intended to provide a method of manufacturing a deformed hole glass nozzle for spinning in the textile industry so as to be created.

It is a built-in glass body that is wound and attached.

Thereafter, the glass body is gradually cooled to a predetermined temperature, taken out of the heating furnace, and the twisted metal wire provided on each tension frame 7 is cut off to obtain a rectangular parallelepiped block shape as shown in FIG. Glass body 15 is formed, and both side surfaces of the glass body where the twisted metal wires 31 and 31 are exposed are cut off by a diamond cutter, and the ridge portion of the glass body 15 is appropriately cut. A glass body 16 having a columnar shape with a circular cross section is formed.

As described above, according to the invention of this application, basically, in a method for manufacturing a deformed hole glass nozzle for spinning, which expresses a highly viscous stock solution for spinning, such as viscose, it has a predetermined cross-sectional shape. A predetermined number of thin metal wires are twisted together to form a stranded wire, and the stranded metal wire is tensioned and wound around a tension frame made of metal in a square shape in plan view. Twisted metal wire plate and special hard glass on the whole surface are installed in a splicing state, and heat-treated under pressure in a furnace, and the twisted metal wire and special hard glass plate are integrated. By welding to form a glass body, a twisted metal wire formed inside the glass body is used to form a nozzle hole with an irregular cross section having a center line in the thickness direction of the nozzle tip and along the center line. By virtue of this, the glass nozzle has a monotonous cross-section nose like the conventional mode. It cannot be a nozzle with holes, so it has a similar function to natural fibers, or has heat retention, water absorption, and weight reduction, and functions such as swelling and elasticity that cannot be obtained with natural fibers. The excellent effect of being able to obtain a chemical fiber having

In this way, the nozzle hole can be modified, and an artificial chemical fiber having a function similar to that of natural fiber, which cannot be obtained by the conventional nozzle hole having a circular cross section, can be obtained. Excellent effect is achieved.

Since the block-shaped glass body thus obtained is cut into slices and molded into nozzle tips, the inside of the nozzle holes and the edge of the outlet in the sliced nozzle tips are processed. Is formed as designed, and since the nozzle hole having the center line in the thickness direction of the nozzle tip can be made sufficiently long, spinning of the raw material liquid such as viscose to be extruded can be obtained, therefore,
Even if hundreds to thousands of nozzle holes are formed in one nozzle chip at a predetermined pitch interval, the spun yarns that are extruded are in contact with each other immediately after extruding from the nozzle holes, and the spun yarns have the designed small diameter. This has the effect of preventing the failure.

Further, when the heat treatment in the furnace is carried out in a non-oxidizing atmosphere under reduced pressure, the stranded metal wire may be wound around the winding groove of the tension frame in winding. Removes air bubbles with bubbles, removes oxygen gas etc. adhering to thin metal wires, and ensures reliable fusion of stranded metal wires and special hard glass, forming irregular nozzle holes as designed That is an excellent effect.

Thus, in the optimum method for producing a deformed hole glass nozzle for spinning, a predetermined number of metal wires having a predetermined small diameter are twisted together to form one twisted metal wire, and the twisted metal The twisted wire is wound around a wire frame and wound around the wire frame, and the twisted metal wire is wrapped with special hard glass, and is heat-treated in a furnace. By fusing a metal wire and a special hard glass plate to obtain a block-shaped glass body, a twisted metal wire is built in the block-shaped glass body and cut into slices at the next stage. When the nozzle tip is obtained by immersing the twisted metal wire contained in the nozzle tip in aqua regia or the like to dissolve and remove the trace, the trace of the twisted metal wire becomes a nozzle hole having a cross-section irregular shape. , It does not have a monotonous circular nozzle hole in the conventional manner, Excellent insulation properties and water absorption, no variation, excellent effect that lightweight chemical fibers can be obtained is exhibited.

Further, by twisting the ultrafine metal wires, the nozzle hole, which is a trace of the twisted metal wire, can be surely obtained in the irregular cross section inside the block-shaped glass body in the heat treatment process in the furnace. The excellent effect that it is possible to ensure that a good quality spinning as described above can be obtained is exhibited.
