Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for directly producing a designed yarn in a roving process.

Conventionally, in order to manufacture designed twisted yarn, as shown in Figure 4,
Spun single yarn made through the spinning process, that is, opening/shrinking and batting process → streamline process → drawing process → roving process → silk spinning process,
The yarns constituting the designed twisted yarn are selected from filaments that are not subject to the spinning process, or their processed yarns, etc., according to the design items such as the number of yarns, count, hue, etc., and are combined. By changing the number of twists, the direction of twist, the relative paper output speed ratio between the yarns constituting the design twisted yarn during twisting, etc., the process goes from the first twisting design twisting process to the double twisting design twisting process using the machine, to create a special appearance. It was manufactured by creating a thread with a texture.

These designed twisted yarns include, for example, what is called a wavy yarn (spiral yarn) as shown in FIG. 3a, and what is called a corkscrew yarn as shown in FIG. 3b.

The wavy yarn (spiral, yarn) shown in Figure 3a is one in which a large-count yarn is wound in a spiral pattern around a core yarn located at the center of the designed twisted yarn. In addition, the corkscrew yarn shown in Figure 3b is heated while surrounding the net count yarn with thick yarn count, and then another pongee count yarn is added and burned in the opposite direction. It can be obtained by Designed twisted yarns made using these thick yarns have the following problems.

In other words, as these thick yarns, usually kasu spun single yarns are used, but when they are fed to the design twisting machine in the next process, they are further burned, so the finished design twist yarns are heated. The disadvantage was that the texture became hard due to repeated twisting.

Furthermore, since yarn that has undergone a spinning process is used, there is a problem in that the cost is high. On the other hand, it is possible to use the roving produced in the roving process as it is and burn it by combining it, but the roving is not strong enough to prevent it from being cut in the design twisting process, resulting in reduced productivity. Workability is significantly reduced and it cannot be used practically. The present invention aims to improve these conventional drawbacks, and furthermore, it is an object of the present invention to obtain a designed yarn with a new texture that has never existed before. That is, in the '1' phase spinning process, when a draft is applied to the fiber east and the fiber bundle is twisted and wound, the core yarn is spun at a speed slower than the traveling speed of the fiber bundle to which the draft has been applied at a position downstream from the draft roller. A method for producing a design yarn, which comprises: supplying a core yarn, merging the core yarn and a fiber east, and twisting and winding the fiber east while combining the core yarn in a spiral shape.

2) The driving shaft drives the draft roller through the top cone drum shaft, and the winding bobbin is driven from the top cone drum shaft through the pot cone drum shaft, winding change wheel, and differential motion device. In a roving frame configured to be driven, a device for supplying core yarn and a core yarn merging section are provided at a position downstream of the draft roller, and a device for supplying core yarn and a core yarn merging section are provided between the core yarn supply device and the draft roller and between the driving shaft and the draft roller. A device for manufacturing designed thread, characterized in that the two are connected at respective transmission sections.

The present invention relates to an apparatus for manufacturing a decorative yarn according to claim 2, characterized in that a variable speed member connects a rigid pot cone drum shaft and a winding change wheel. Next, details of the present invention will be explained with reference to the drawings.

FIGS. 1 and 2 show an embodiment of the present invention. In FIG. 1, a core thread supplying device 35 for supplying the core thread 26 is placed in front of a draft roller 15 of a roving frame. . Downstream of the draft roller 15, the fibers 23 spun from the draft roller 15 are passed through the guide bar 30.
The core yarn 26 is fed at a slower speed than the above speed.

The above-mentioned core yarn 26 and fiber east 23 are combined near the guide parr 30, are simulated by the flame propagated from the head of the flyer 13, are combined and combined, and become the yarn 31, which is attached to the bobbin 10 of the roving frame. It is rolled up.

The fiber 23 herein refers to a fiber obtained by drafting the sliver 21 made of short fibers housed in the can 201 by the draft loaf 15. (hereinafter referred to as sardine fiber)
The yarn 31 obtained in this step) corresponds to the yarn obtained in the conventional pre-twisted design yarn process using a dedicated design twisting machine.

(hereinafter referred to as ply-twisted design yarn). This depends on the application.
However, if necessary, multiple ply-twisted design yarns may be doubled in the plying/ply-twisted design yarn twisting process, or they may be combined with other component yarns to increase the count of each component yarn. By changing the hue, relative paper speed ratio, number of twists, direction of twist, etc., it is possible to obtain a desired design yarn. When manufacturing a first-twisted design yarn by the method and apparatus of the present invention, the count, hue, relative paper speed ratio, etc. of the core yarn 26 and drowned fibers 23 that make up the first-twisted design yarn are determined depending on the use of the design yarn. Although it can be changed depending on the situation, in order for the strength of the ply-twisted design yarn to be greater than the minimum strength required for work, the effect of the core yarn 26, which is one constituent yarn of the ply-twisted design yarn, is necessary. It is desirable that the core yarn 26 is located inside or inside the first twisted design yarn.

This is the drowned fiber 23 spun by the draft roller 15.
This can be achieved by doubling and twisting the yarns at a slower rate than the successive yarn speed of , thereby creating a structure in which the drowned fibers 23 face each other around the core yarn 26. The core yarn 26 referred to here may be one having sufficient strength to allow production and work such as a normal yarn retrieval process to be carried out without any problems, and may be a single weft yarn obtained through a normal spinning process. , commonly used filament yarns or processed yarns thereof, or two or more yarns of these yarns may be used. In the first twisted design yarn obtained with such a structure, force is applied mainly to the core yarn constituting it during operation, so that a strength greater than the required minimum strength can be easily obtained.

The pre-twisted design yarn is required to have various forms depending on its use, and various forms can be created by changing the state of the synthetic fibers 23 around the core yarn 26. is obtained. The state of imitation varies depending on the number of twists of the pre-twisted design yarn and the relative sprouting speed ratio of the core yarn 26 and the artificial fiber 23, in addition to the count of the constituent yarns, especially by changing the number of twists. Changing the state of imitation is simple and highly effective. It is also possible to produce twisted design yarn, but in this case, the range of twist numbers used in the normal spinning process is narrow. Therefore, in order to greatly expand this range, it is necessary to insert a transmission member. Normally, in a general roving frame, the number of twists is F. It is determined by the length of the feed from the controller 16 and the rotation speed of the flyer 13 fixed to the spindle.
In the roving frame in the method and apparatus of the present invention, the number of twists of the first twisted design yarn is determined by the length of the yarn delivered from the delivery roller 27 of the core yarn supplying device 35 and the length of the yarn delivered from the flyer 13.
It is determined by the rotation speed of FIG. 2 is a diagram showing the main parts of the gear connection system of the roving frame, and the number of twists is the twist change wheel A attached to one end of the driving shaft 12, and the gear B attached to the top cone drum shaft 19. The speed change member W interposed between the gear C attached to one end of the top cone drum shaft 19 and the gear D attached to one end of the front roller 16 can be changed depending on the date. I can do it. Also, at this time, the winding tension of the thread 31 being wound on the bobbin 1 is adjusted by using the speed change member J interposed between the pot cone drum shaft 36 and the winding change wheel N3 as necessary. You can. Next, another factor that suppresses the state of imitation of the first twisted design yarn is the relative twilling speed ratio of the core yarn 26 and the fiber east 23 that imitates it, and by changing this ratio, the It is possible to create various loops and change the simulated state. The relative spinning speed ratio of the core yarn 26 and the pseudo fiber 23 is determined by the pinion E attached to the front roller 16 shown in FIG.
Since this can be changed by the speed change member G interposed between the pinion 8 and the pinion 8 attached to one end of the delivery roller 27, a desired interlocking state of the core yarn 26 and the envy fibers 23 can be obtained. The transmission member referred to in (a) may be a combination of a plurality of gears, or may be a combination of other power transmission means such as a pulley.

In addition, since various forms are required depending on the purpose of the designed yarn, it is not necessary to always use all of these transmission members, but it is possible to use one or more in combination and vary the number of twists and the structure of the imitation. , threads of various shapes can be produced.

The bottom-burning design yarn produced by the method of the present invention can be used as is, and can be combined with other yarns etc. in the ply-twisting design twisting process to create a design yarn with further variation. However, as shown in Figure 5, in the tsuchigami process, the Shimomene design yarn is directly made, so the twisting process that was necessary to make the design twisted yarn, such as the kasugami process, is eliminated. This reduces the number of steps by at least two steps, and at the same time improves the conventional problem of a hard textured yarn due to too many twists.

In addition, since the designed yarn produced by the method of the present invention is made by directly drowning the almost untwisted pseudo fibers 23 into the core yarn 26, it is possible to create a new type of designed yarn. It is possible to utilize the texture and characteristics of the raw material without covering it up with strong twisting.

By omitting the above-mentioned process, the cost of manufacturing yarn with decorative design can be reduced, so it can be used not only in the field of high-end clothing, which conventional twisted yarn with design has, but also in the field of consumer clothing, interior products, and building materials. Its use can be expanded to a wide range of other fields.

Next, examples using the method of the present invention will be shown. Example '1}
Cotton thread 1 no 67. as core thread. Use four pieces of machine m (meter count, same hereinafter), and use one piece of 100% polyester, 1/1.3 skin m as the drowning fiber.

Using the variable speed member G, the spinning speed of the sardine fiber is adjusted to 1.
Set it to 5 times, use the speed change member, W, and set the number of twists to 265.
times/meter, the tension of the thread was adjusted using the variable speed member J, and the thread was wound onto a bobbin. The resulting yarn has a structure in which the core yarn is covered with pseudo fibers. (corresponds to ply-twisted design yarn) In addition, as a presser yarn, striped yarn 1/33.8 mm
One strand of the first-twisted design yarn is over-fed by 5%, and twisted in the opposite direction with a twist count of 15 sub/meter to give a twist of 1/0. I got a carp m design thread. This yarn has the appearance of a conventional wavy yarn (spiral, yarn). [2) Cotton thread 1/67. A 1/2. state m 1
Using this method, it is spun at a speed of 1.8 times that of the core yarn.
It was made into a pre-twisted design yarn with a twist count of 130 turns.

The resulting yarn has a structure in which the sardine fibers form loops around the core yarn, and the loops have a very loose form, creating a completely new form not found in conventional twisted yarns. A designed thread was obtained.
