Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

(A) Spinning machine

The spinning machine can manufacture a composite yarn from two coarse yarns, and for example, pull the coarse yarns 311 and 312 from the towing unit 1 as shown in FIG. 1 and simultaneously apply the coarse yarns 311 to the front rollers 131 and 132, respectively. The fiber bundle 321 and the fiber bundle 322 of the coarse thread 312 are supplied, and the twisted yarn 33 is twisted by the spindle part 4 and wound around the failure 34. The pulling section 1 includes a rear roller 11, a rear upper roller 11T, an intermediate roller 12, an apron 12T, front rollers 131, 132 and front upper rollers 131T, 132T.

(B) rough thread

Fiber of coarse thread is synthetic of natural fiber such as cotton, hemp, silk, wool, regenerated fiber such as rayon, cuprammonium rayon, high strength regenerated cellulose fiber (e.g., dencel), nylon, polyester, etc. Short fibers such as fibers and combinations thereof can be used. The fibers of the two coarse yarns may be fibers of different colors or fibers of different dyeability. The different color may be a fiber original color or a dyed color.

(C) Driving the front roller

The front rollers 131, 132 are independently driven controlled to pull the fiber bundles. The front rollers 131, 132 have corresponding front upper rollers 131T, 132T, for example, as shown in FIG. 1, and are driven by respective motors M231, 232, the motors M231, 232 being controllers, respectively. (221, 222). These controllers 221 and 222 switch the driving by the 1 / f wave signal 21 and the driving of the normal constant speed.

The control of the controllers 221, 222 is for example, when one coarse thread is supplied with a 1 / f wave signal, the other coarse yarn is supplied at a normal constant speed (reference speed), and has a complex having 1 / f wave. Yarn can be manufactured.

(D) 1 / f wave signal

When a 1 / f wave signal is analyzed in the power spectrum of a time series signal, the intensity of the frequency f is almost inversely proportional to the frequency (proportional to 1 / f), which is related to the basic rhythm fluctuations of the human body, and is a natural sense Or hand-made irregular feelings. Looking at it differently, humans get tired of receiving the same stimulus over and over, and this is counterproductive when the change is quite severe. For example, see Korean Patent Application No. 96-18096).

The 1 / f wave signal can be obtained from a mathematical example produced by calculating a predetermined coefficient with a random number sequence, and can be prepared by a known method using a computer or the like (for example, Korean Patent Application No. 96-18096). Reference).

In addition, since the 1 / f signal has a power spectrum having a frequency component f is proportional to 1 / f ^k , it means that k has a value around 1 and has a spectrum similar thereto.

Hereinafter, embodiments of the present invention will be described.

(A) Changing the feed rate of the bundle of fibers to 1 / f wave

When the two rough yarns 311 and 312 are supplied as shown in FIG. 1, both of them pass through the normal rear roller 11 and the intermediate roller 12, and then independently drive left and right front rollers 131 and 132. Two fiber bundles 321 and 322 are fed to the front upper rollers 131T and 132T which are driven accordingly.

The fiber bundle on one side is towed at a feed rate that changes with a 1 / f wave, and the fiber bundle on the other side is towed at a constant feed rate without change. As an example of the change of the 1 / f wave, the surface speed of the front roller 132 is changed to 1 / f wave with respect to the surface speed 1 (constant feed speed Vo) of the front roller 131 as shown in FIG. 2A. . The 1 / f wave signal is, for example, defined to change within a set variation range (between 1.00 and 1.25) of the supply speed.

When the surface speed of the front roller 132 for pulling the fiber bundle 322 is 1.00 with respect to the front roller 131 (in the L portion of FIG. 2A), since the fiber bundles 321 and 322 are supplied at the same speed, Appear on the surface at substantially equal intervals, for example, as shown in FIG. 2B.

In contrast, when the surface speed of the front roller 132 that pulls the fiber bundle 322 is 1.25 with respect to the front roller 131 (in M portion of FIG. 2A), the fiber bundle 322 is the fiber bundle 321. The fiber bundle 322 is wound around the outer circumference of the manufactured composite yarn 33 and exposed, for example, as shown in FIG. 2C.

Therefore, the speed difference between the front roller 131 and the front roller 132 is 0 in the L part, and the speed difference is the maximum in the M part. At this time, the controller 221 of the front roller 131 is controlled without changing.

By controlling in this way, the pattern of the two fiber bundles, for example, a 1 / f wave change occurs in the pattern between the L and M patterns of FIG. 2, and the fiber bundle 321 and the fiber bundle 322 are generated. If fibers of different colors are used, a thread having a natural wooden feel can be obtained. In addition, by using such a composite yarn, a knitted fabric having a natural wooden feel can be obtained.

(B) changing the feed rate of the fiber bundle to a time pitch of 1 / f wave.

In addition, a fiber having a natural wood texture can be obtained by using a different type of fiber having different dyeing properties from the fiber bundle 321 and the fiber bundle 322 to form a composite yarn, and then dyeing the composite yarn. In such a case, a knitted fabric using a dyed composite yarn or a composite yarn before dyeing is used as a knitted fabric, and then dyed thereafter, a knitted fabric having a natural wood feel can be obtained.

The feed rates of at least one bundle of fibers are varied in two stages. At this time, the pitch of the supply time of one step is changed according to the 1 / f wave. The feeding speed of the other fiber bundle may be constant or the pitch of the feeding time may be changed in a 1 / f wave opposite to that of one fiber bundle.

For two fiber bundles, when the pitch of the feed time is changed according to the 1 / f wave, for example, as shown in FIG. 3, the front roller with respect to the surface velocity 1 of the front roller 131 in one step. The surface speed of 132 is 1.25, the surface speed of the front roller 132 is 1 with respect to the surface speed of 1.25 of the front roller 131 in the other step, and the supply time of at least one step is 1 / f wave. Change to pitch

When the surface speed of the front roller 131 is 1.25, the fiber bundle 321 is thin and long with respect to the fiber bundle 322 of the front roller 132 (surface speed 1.0), as shown in part J of FIG. The fiber bundle 321 is wound around the outer circumference of the yarn 33 to be exposed. On the contrary, when the surface speed of the front roller 131 is 1.0 and the surface speed of the front roller 132 is 1.25, the fiber bundle 322 is thin with respect to the fiber bundle 321 as shown in the portion K of FIG. 3. It becomes long and the fiber bundle 322 is wound around the outer circumference of the manufactured composite yarn 33.

The pattern of the composite yarn 33 thus produced is shown in FIG. 3. The pattern of FIG. 3 is a case in which the rotation of the front rollers 131 and 132 is controlled such that the length of the portion 311 where one bundle of fibers is exposed to the outer circumference is about 20 mm. Furthermore, the surface speed of the front roller 132 is 1.25 steps The supply time in is changed to the pitch of 1 / f waves (t1, t2, t3 ...).

As such, the pattern of the two bundles of fibers 321 and 322 causes a 1 / f wave change, and when the bundles of fibers 321 and the bundles of fibers 322 use different colored fibers or different types of fibers with different dyeability, Like (a), yarns or knitted fabrics with a natural wooden texture that are neither regular nor irregular can be obtained.
