[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic view showing a method for producing a design twisted yarn a according to the present invention. The outline of the method for producing the design twisted yarn a according to the present invention will be described with reference to FIG.
Core yarn 1 made of FTY or polyurethane and having elasticity
And the slack yarn 2 made of polypropylene with the first twisted portion 3
By twisting in the S direction (clockwise) at, a loop yarn a ′ having a loop 2a formed by the slack yarn 2 is obtained. Next, the slack yarn 2 is fixed to the core yarn 1 by the presser yarn 4 made of the same polypropylene as the slack yarn 2 so that the design twist yarn a
Is formed (FIGS. 4 and 5). Finally, the design twisted yarn a is wound by the rotation of the spindle 7 via the slip stopper 11.

As the above-mentioned FTP, use is made of a polyurethane filament covered with nylon wound around, or a polyester filament covered with nylon wound around nylon. In the case of polyurethane, the filament used as FTY is 20 to 45 dT.
(Decitex), 30 to 160 dT for nylon
When set within the range, good results were obtained. In the present embodiment, the former is used. If the filament is less than the above range, the filament becomes too thin, the strength is reduced, and the filament is easily cut. Conversely, if it is above the above range, the return when extended will be strong, and you will feel the pressure. Also, the polypropylene filament constituting the slack yarn 2 in a bundle is 75 to
Those having a range of 1000 dT (decite) are preferable, and 120 to 680 dT is particularly preferable. If the polypropylene filament is 75 dT or less, it is soft and has a good feel, but the strength is reduced. When the filament is 1000 dT or more, the filament becomes hard and has a stiff feel.

Next, the characteristic portion of the method for producing a design twisted yarn according to the present invention will be described. FIG. 2 shows a state in which a thread-wound core thread 1a is set on a conventionally used core thread mounting member 8. The core yarn 1a is made of FT having elasticity.
Since Y or polyurethane is used, when the core yarn 1a is sent out and reaches one end 1b of the bobbin, the core yarn 1a is easily entangled with the core yarn mounting member 8, and the yarn breakage is liable to occur. In order to solve this problem, as shown in FIG. 3, the core thread mounting member 8 has a bag slightly larger than the diameter of the thread-wound core thread 1a, and one end close to the tension adjusting device 9 is opened. When the bag 10 is attached and the core yarn 1a is attached thereto, the core yarn 1a can be sent out to the tension adjusting device 9 at a constant speed without being entangled with the core yarn attachment member 8.

FIGS. 4 and 5 are explanatory diagrams showing a state in which the core yarn 1, the slack yarn 2 and the presser yarn 4 are being twisted. Twisted yarn a has the upper end fixed and the lower end twisted to the right.
Twist (right-handed), when the lower end is twisted to the left, Z
This is called twisting (left twisting). First, core yarn 1 and slack yarn 2
Is S-twisted by the S-twist portion 3 shown in FIG. At this time, by making the supply speed of the slack yarn 2 higher than the supply speed of the core yarn 1, a loop yarn a ′ is formed in which annular (loop-like) slack is continuously formed at regular intervals (FIG. 4). . When an example of actually twisting the loop yarn is shown, when the supply speed of the core yarn 1 is 10 m / min, the supply speed of the slack yarn 2 is 37 m / min.

Next, as described above, the core yarn 1 and the slack yarn 2
And the presser yarn 4 are Z-twisted by the Z twist portion 5 shown in FIG.
By the Z twist of the presser yarn 4, the core yarn 1 is fixed to the slack yarn 2, and the state in which the annular slack is formed at regular intervals can be maintained. The supply speed of the core yarn 1 and the supply speed of the slack yarn 2 may be arbitrarily changed. As the presser thread 4, polypropylene, nylon, polyester, or the like is used. As a result of trial production, polypropylene having a low water absorption rate, that is, polypropylene with good drainage, was suitable.

Here, in the S twist portion 3, S twist (right twist)
Is preferably twisted in the range of 800 to 1200 T (rotation) / m (meter), and in the Z twist portion 5, the Z twist (left twist) is preferably twisted in the range of 200 to 600 T / m. Although this is only an example, in order to correspond to the supply speed of the core yarn 1 and the slack yarn 2, the S twist (right twist) is 1030 T / m in the S twist portion 3 and the Z twist (left twist) is in the Z twist portion 5 (left). When the twist was set to 425 T / m, good results were obtained. The design twist yarn a is wound around the bobbin by the rotation of the spindle 7 after the slip is prevented by the slip stopper device 11 shown in FIG. 1 so as not to slip before winding the design twist yarn a around the bobbin.

Here, the rotating direction of the spindle 7 is such that the extra torque applied to the design twisted yarn a is reduced in the process of forming the design twisted yarn a by alternately twisting the loop yarn a ′ and the presser yarn 4. Rotate. As an example, in the case of the above setting, the spindle 7 is rotated so as to rotate counterclockwise when viewed from above, as indicated by the arrow in FIG. 1, so that the rotation speed is about 2400 T (rotation) / m (mail). Is set to This eliminates the necessity of performing the heat treatment that has been conventionally required in the finishing step of the design twisted yarn, thereby increasing the production efficiency.

Further, when a product is manufactured by using the design twisted yarn according to the present invention, it occurs when the product is manufactured by knitting from a state where the conventional design twisted yarn and a stretchable system are separated. Since skew can be prevented and the tension of the yarn having elasticity can be uniformly applied to the entire product,
Since the yarn is not knitted so that the tension of the yarn becomes uniform, the directionality generated in the product can be eliminated.

In the design twisted yarn a manufactured by the above-described method, the core yarn 1 is made of stretchable FTY or polyurethane, and the slack yarn 2 and the holding yarn 4 are made of polypropylene. Since it is a hydrophobic polymer, it has an antibacterial effect and is excellent in strength, abrasion resistance and chemical resistance. On the other hand, the polypropylene used for the slack yarn 2 is
Since there is no functional group capable of forming a hydrogen bond or an ionic bond, there is also a disadvantage that dyeability is poor. Therefore, if the core yarn 1 is preliminarily colored with FTY or polyurethane, it is possible to make it look as if it is colored as a whole in the state of the design twisted yarn a.

Products using the above-described design twisted yarn include glove-shaped rubbing for washing body with soap at the time of bathing, glove-shaped cleaning tool for washing dishes with detergent in a kitchen, towel, and towel And various products such as cosmetic tools such as puffs. This is because polypropylene is a hydrophobic polymer and therefore has an antibacterial effect because it is a hydrophobic polymer, and the twisted design yarn has elasticity. The effect is that the foaming of the soap is also good.

FIG. 6 shows a glove-shaped cleaning tool a0 formed by knitting the twisted yarn a configured as described above. The glove-shaped cleaning tool a0 is obtained by knitting the twisted yarn a configured as described above using a flat knitting machine or the like. 6 is a simplified representation of the knitting structure itself, omitting the twisted yarn a as a single yarn, and includes a loop 2a of the slack yarn 2 included in the twisted yarn a, a presser yarn 4, and the like. Is omitted. The glove-shaped cleaning tool a0 has moderate elasticity, and countless small loops 2a formed by the slack yarn 2 of the twisted yarn a appear on the surface thereof. The loop 2a is similar to a case where the yarn is knitted like a pile using ordinary yarn. Therefore, it has a good texture when it comes into contact with the skin, and it has good foaming, especially when used with a bath cleaning tool, and has a soft feel during cleaning, which is suitable for washing a body or face. The above-mentioned glove-shaped cleaning tool a0 was formed by knit knitting (knitting), but the method of knitting the glove-shaped cleaning tool is not limited to this, and for example, flat knitting, pile knitting, tack knitting, and jaguar knitting. -Any existing knitting method, such as knitting, may be used. The glove-shaped cleaning tool knitted using the twisted yarn a may be a five-finger type or a mitten.

As described above, in the twisted yarn a manufactured as described above, the loop 2a is formed in parallel with the yarn itself.
For example, it has a structure similar to a pile of ordinary yarn. That is, the conventional cleaning tool gives a good texture by devising the way of knitting the yarn.
Has a loop 2a formed by cross-twisting, so that a structure in which the loop 2a is formed with an appropriate density can be easily knitted by a usual knit knitting, and has a soft texture. .

Further, the glove-shaped cleaning tool of the present invention may brush the surface to raise the twisted yarn exposed on the surface, like the glove-shaped cleaning tool a1 shown in FIG. The glove-shaped cleaning tool having a twisted yarn raised as described above has fine fibers raised from an infinite number of loops and becomes as if it were a wool. The feel of the cleaning tool a0 is further softened.

FIG. 8 shows a towel a2 formed by plain weaving the twisted yarn a configured as described above. This towel a2, like the above-mentioned glove-shaped cleaning tool a0, has an infinite number of loops 2a exposed on the surface, so that it has a good feel when touching the skin. In particular, when used for washing the body during bathing, the foam is good. In addition, the feel received during washing is soft, and there is a good feeling of use that is not available with conventional towels. The above-mentioned towel a2 is formed by plain weave, but the weave of the towel may be other than plain weave, such as twill weave or satin weave. Further, the towel may be formed by knitting by knitting or the like. Further, the towel formed using the twisted yarn a may be buffed with its surface buffed like a towel a3 shown in FIG. Furthermore, towel a2
A cloth, a puff for makeup, or the like can be formed by the same manufacturing method as that for the towel a2 or the glove-shaped cleaning tool a0 described above.
