Description

  The present invention uses onions, ancient species of ancient cocoons, etc., which have unevenness in thickness, and cocoon yarns drawn from a plurality of cocoons are entangled with each other, causing knotting due to swelling, collapse of the cocoon layer, etc. The present invention relates to a reeling method that can be obtained by using a mass-produced cocoon without performing.

Since ancient times, yarns such as ancient varieties have been reeled out and wound, but these have many thin cocoon layers and small sized unsatisfactory cocoons, resulting in thick and non-uniform thickness yarns, Its use has been declining due to the passage of verses. However, the user has now reviewed it due to its unique feel, and its production has come to be desired.
However, there is a limit to collecting raw material cocoons, and using mass-produced cocoons is equivalent to conventional products using ancient cocoons, but it was difficult to make such yarns.

  In addition, the yarn produced by mass production has been improved as a varieties with uniform thickness and less occurrence of knots at the time of reeling. In order to prevent the wrinkled wrinkles during spinning from coming into strong contact with each other or to remove wrinkles unrelated to the wrinkled wrinkles during spinning as appropriate, such as by falling or peeling. For example, a conical cap having an outlet for reeling hot water located at the center of the graining in the spinning tank is provided, and the spinning concentrate is allowed to flow out of the cap into the tank yarn tank, thereby concentrating on the lifting part. A device is known in which a sprinkle is diffused to increase the diameter of the circle, and the fallen or skin is poured into a wrinkle collecting tank outside the yarn spinning tank by the flow of the spinning water discharged from the discharge port (Patent Document). 1). In the above apparatus, the reeling hot water flowing out from the cap is only for the purpose of diffusing the grained ridges, and is not intended to strongly contact the grained ridges and damage the ridge layer. It is not intended to move the kite in a strong flow because it is flowed to the kite collection tank.

  In addition, when spinning from ancient cypress, onion, etc., the cord surface is lightly boiled with a cord with a cord, etc. Making raw silk has been done by skilled workers. In addition, the cords made by Kosuge were inefficient and difficult to make knots using Kamisu.

As mentioned above, it is necessary to prepare a mass-produced cocoon that is similar to a knotted and thick thread made from ancient buds, onions, etc. There are various obstacles such as occurrence problems.
Japanese Utility Model Publication No. 63-9687

In view of the above points, an object of the present invention is to obtain raw silk having thick spots and knots that are produced from onions and ancient seed pods using mass production cocoons.
Also. An object of the present invention is to obtain a spinning method that does not require equipment members for the cording / scoring process by simultaneously performing the spinning process and the cording / scoring process in a spinning tank.

The method of claim 1 is a reeling method of a kite yarn, wherein the reeling tank having means for stirring the spinning hot water in the spinning tank that collects and lifts up the arranged cords, Unsorted cocoons such as cords are introduced, and the stirring of the spinning yarn causes impact of the spinning yarn on the cocoon layer, contact between the cocoon layers, and collision. A cord formed by winding the cord together with the choreograph that has generated knots due to the collapse of the coffin layer caused by the stirring. It is characterized by simultaneously performing cord / joint / winding.
In the method of claim 2, in the spinning method according to claim 1, the cord is agitated with hot water in the aquarium so that the dredging layer collapses due to water pressure on the dredging layer, contact collision between the dredging layers, and the like. In other words, it is characterized in that it is carried out by separating the string end from the string layer and starting a cord.
According to the method of claim 3, in the spinning method according to claim 1, the hot or cold of the hot water is added to the finely tuned yarn that is raised in the stirred hot water. It is characterized by clumping by stirring and generating knots.
In the method of claim 4, in the spinning method according to claim 1, the roughness or the knitting is intricately entangled with the knitting knitting yarn that is being lifted in the agitated reeling hot water. It is characterized in that enormous parts are produced in the raw silk yarn that has been brought together.
The method according to claim 5 is characterized in that, in the spinning method according to claim 4, when the enormous part is made large, the spinning speed is made small, and when the enormous part is made small, the spinning speed is made large. And

In the method of the present invention, since the scissors are made to flow on the agitated spinning hot water in the spinning tank, the generation of knots may be caused by contact with each other or various members in the spinning tank. Due to this agitation state and the reeling speed, the warp yarns entangled in the tank are closely aligned in a certain position and entangled in a swollen state in a certain position, and partly The other thread is wrapped around the center of the thread, and the number of threads, Young's modulus, thread unevenness, etc. can be changed appropriately depending on the speed of the vortex. A variety of yarns close to the yarn can be made.
Further, in the reeling method of the present invention, when the cocoon is put into the reeling tank, the cord cord is not preliminarily performed, so that no means for cord cord cording is necessary at all. You can omit the mechanism.

As an apparatus for carrying out the method of the present invention, it is necessary to create a turbulent flow and / or vortex flow in the spinning layer. An example of creating the flow is given below.
As a first example, in a case where a partial rotor blade is provided in the center of the tank bottom, if the rotation direction is constant, a vortex extending in the direction of the rotation center axis of the rotor blade is created, and the wall surface of the vortex becomes a hyperboloid A close shape. Free vortex in fluid mechanics.
As a second example, when the diameter of the rotor blade provided in the center of the tank bottom is close to the diameter of the tank and the water depth is shallower than the diameter, it becomes a vortex that is close to the forced vortex in fluid mechanics, and the shape of the water surface in the tank Becomes a paraboloid. The use of the rotary blades of the first and second examples changes the state of the vortex generated in the tank.
As a third example, when the rotational direction of the rotor blade is repeated forward and backward in the above, turbulent flow is generated in the spinning tank.
As a fourth example, turbulence is generated by vibrating the entire tank.
As a fifth example, it may be generated by flowing a water flow or air flow from the outside of the tank with a pump or the like.
As an example of an apparatus for carrying out the method of the present invention, FIG. 1 shows a schematic cross section of an apparatus for generating a free vortex in a tank and spinning the yarn.
Reference numeral 1 denotes a reeling tank, which is a tank having a rectangular cross section that also serves as a rope tank and is open at the top. A stirring impeller 2 is provided at the center of the bottom, and its shaft 3 is connected to a motor 5 via a power transmission mechanism 4. 6 is a collector, and 7 is a frame. Although not shown, there are provided a collecting means such as a kite, a fresh rice cake feeding means, a reeling-up hot water injection means and the like.

The collecting means such as a kite is provided with a return line that receives the spinning water overflowed from the spinning tank 1 and returns it to the spinning tank again.
A cocoon 9 having the number of grains corresponding to the target fineness of the yarn 8 to be advanced is put into the reel 1, the cocoon 10 is passed through the collector 6, and the reel 7 is rotated to rotate the cocoon 9 in the reel 1. The silk thread 10 is gathered by the gathering device 6 and wound around the reel 7. During this time, the spinning hot water 11 in the spinning tank 1 is stirred by the stirring rotary blade 2. With this rotation of the rotary blade 2, the reeling hot water 11 above the rotary blade 2 starts to rotate in the same direction as the rotary blade 2 rotates, and draws a hyperboloid 12 centering on the axis 3 of the rotary blade 2, The scissors 9 in the reel 11 are swirling and stirring in the vicinity of the hyperboloid 2.

As a result of the above stirring, the cocoon 9 in the reeling hot water 11 is produced by generating coarse or ordered due to the collapse of the cocoon-layer yarn cocoon due to contact with adjacent cocoons or the rotor blades and the tank wall surface. Coarse or aligned is joined by adding bulges to the yarn by entanglement with the silk thread being lifted by stirring, and the silk thread 10 is wound up while generating knots, and further gathered by the collector 6 It is wound up on the reel 7.
New cocoons are introduced when the cocoons in the reeling tank are lifted and the available cocoons are reduced. As soon as the cords are gone, it becomes habitual and can be spun. Therefore, there is no need to provide a cord / text abstracting means.
Table 1 shows the characteristics of the yarn when the reeling speed is changed in the above-described manner.

Next, the results of each item in Table 1 will be described.
1. Average number of soot grains Decreases at higher speeds.
2. Search effect The search effect by this method is remarkably increased in the case of Table 2 below.
3. Fineness (see Fig. 2)
At low speed, the increase in the fineness due to the entanglement of the yarn is large, and the fineness decreases as the speed increases.
4). Fineness increase index (see Fig. 3)
The definition of the fineness increase index is as follows.
Fineness increase index = measured fineness / theoretical fineness (number of fine grains x single fineness (2.6))
5. Spinning tension (see Fig. 4)
It gets bigger at higher speeds.
6). Young's modulus (see Fig. 5)
It is low at low speed, and the Young's modulus increases greatly at high speed.
In general, a yarn having a low Young's modulus is easy to stretch and bend. In other words, it can be said to be soft. As a factor for lowering the Young's modulus, when the spinning speed is low, the stress applied to the yarn is reduced and the Young's modulus is reduced. On the other hand, when the spinning speed is increased, the spinning tension is increased, and in an extreme case, the thread becomes stiff and the Young's modulus is increased so as to be called a wire thread.
From the viewpoint of the shape of the yarn, when the kite crimp remains in the yarn or when the yarn is entangled and the yarn is not aligned, the slack can occur at the initial stage of measurement, resulting in a lower Young's modulus. That is, the arrangement shape of the yarn is also a factor that lowers the Young's modulus.
In the case of the yarn made by the method of the present invention, the Young's modulus becomes low when the spinning speed is low. The lower the spinning speed, the smaller the spinning tension, the more the shape of the kite crimp remains, and the more the yarn becomes entangled. The shape is one of the causes. When high speed reeling is performed, the yarns are aligned, and the yarn tension increases, so the Young's modulus increases.

Thread unevenness and nodes (see Figs. 6-9)
Overall, the yarn is twisted (twisted) due to rotation as compared with the raw silk in the control group (FIG. 8). This can be said to be effective in preventing fluffing due to loosening of threads and threading in subsequent processes such as scouring, dyeing and weaving.
At low speeds (FIG. 6), many yarns are thick and the nodes are long. It is greatly influenced by the vortex and has a great deal of entanglement. At high speed (Fig. 7), the thread becomes thinner and there are fewer nodes. In other words, the way in which the knots are put out is affected more and more often when the speed is slow. Therefore, if the winding of the small frame is stopped for a certain time during the reeling, a more active enormous amount of knots can be made.
The raw silk in the control group shown in FIG. 8 is a raw silk that is wound with 150 regular grains with a target automatic reeling machine at 350 deniers. It is a thread. The Young's modulus is also a standard value for raw silk.
The ball yarn shown in FIG. 9 is a countersink thread, and as can be seen from the figure, there are uneven yarns and many long knots. In the case of countersink, the Young's modulus is spun at a high speed, but since the temperature of the reeling hot water is as high as about 90 ° C., the Young's modulus is lower than that of normal raw yarn.

Next, FIGS. 10A and 11A show the relationship between the reeling speed and the establishment of knots. The shapes of the nodes formed at the positions indicated by alphabets in each of the above figures are shown in the following figures B, C,..., And show the correspondence between the winding speed and the state of the yarn formed at that speed.
FIG. 1O is a graph showing the relationship between the winding speed and the spinning time in which the spinning speed is instantaneously and randomly changed to a high and low appropriate speed. A clause has been made. The winding speed is increased from a predetermined low speed to a high speed in a very short time, and after performing a constant speed reeling for a predetermined time, the speed is decreased in a very short time to maintain a low speed state. Then, when the speed is decreased from the high speed to the low speed, the reeling tension that has been applied so far decreases, so that the kite thread pulled up near the center of the reeling tank loosens momentarily, and those threads are wound, and the knots are formed as shown in FIG. 10C. It becomes. When the spinning speed is changed from low speed to high speed, such a knot cannot be made, and there is no particular change in the yarn as shown in FIG. 10F. It is clarified that even if the rising speed is made constant in the middle as in E, no particularly noticeable node is produced as shown in FIG. 10E. As shown in FIG. 10A, when the spinning speed is instantaneously below 0, that is, when the winding is stopped and reversed, the section shown in FIG. 10D is formed, and the winding is limited to a very small range. It has become a shape.
By using the above method, it is possible to see the occurrence of knots at the location by giving the change point of the reeling speed. Therefore, in the sense of controlling the occurrence of uneven thickness and knots on the thread, However, if the reeling speed is switched between two stages, high speed and low speed, at predetermined intervals as shown in FIG. 11A, yarns having knots at regular intervals can be obtained. I can do it. The node at the position shown in FIG. 11B is made in the same manner as the node at the position shown in FIG. 10C, and FIG. 11C is the same as FIG. 10F. If the motor control is performed using random numbers when changing the winding speed, the occurrence intervals are scattered, and natural unevenness and nodes can be generated. It is also possible to derive from this, for example, to change the frequency of classic, waltz, and healing music, and to control the motor and control the occurrence of knots based on that.

In the method of the present invention, the cocoons that are being lifted are brought into contact with each other in the reeling hot water and the occurrence of coarseness or knots is observed. However, it is also possible to open the way to the use of defective bags that are difficult to get out of production.
In addition, each function of the cord and abstract of the present invention can be used independently as a cord portion and a joint portion of another reeling machine.
