Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a composite bulking device that simultaneously fluidly treats core yarn and effect yarn and then performs false twisting. As shown in Figure 1, the publication No. A composite bulking device has been proposed in which a core yarn supply roller (3), an effect yarn supply roller (II), and a fluid treatment nozzle (/) are provided. Even if the supply solar (3) in the twisting machine is used in conjunction with fluid processing, it is unavoidable to install both the core yarn supply roller (3) and the effect light supply roller (lI), which requires large equipment. There were drawbacks that required investment.

The present invention provides an inexpensive compound bulking device that eliminates the drawbacks of the conventional devices, and the gist of the invention is to provide a core yarn supply roller, an effect light supply roller, and a compound bulking device. Between the yarn take-up roller, there is a fluid treatment nozzle, a twisting guide, a heater, a balloon prevention guide,
and a false twist spindle are provided in the above order.

The present invention will be described in detail below with reference to the drawings. Figure 2 is a side view of the device according to the present invention.
is from its supply roller (&), and the effect yarn (co) is from its supply roller (III) with the same fluid treatment/, (le Cl0)
The effect yarn (, 2) is overfed from the core yarn (1) for fluid treatment, and then the twist prevention guide (//), the heater upper guide (6), the heater (7), and the balloon prevention guide (
/C), the false-twisting spindle (J) is sequentially passed through the false-twisting process, and finally the material is taken off by the take-off roller (9).

In this case, unless the twist guide (//) is used, the nozzle (1
0) and the core yarn (in the nozzle (IO1)).
Not only will this cause poor entanglement between the 1) and the effect yarn (a), but also the
The yarn running between the and nozzle (/) causes yarn pretension, resulting in an unstable processing state.
//) pulls out the yarn in a direction perpendicular to the nozzle (io) and connects the yarn pulled out from the nozzle (10) with the guide (j
It is necessary that the angles of the thread running between 1) and 6) are acute angles, but the angles may be changed depending on the material of the guide (//), etc.

The overfeed rate of the core yarn (1) and the effect yarn (K) during fluid treatment is regulated by the speed of the roller (S) and roller (4t), respectively, centering on the roller (9). Therefore, roller C3) (4'
) (3) and fluid treatment by nozzle (/) and roller (
j) Although the subsequent false twisting process is said to be continuous, it is not a separate mechanism from the machine surface.

The role of the roller (3) during fluid processing in Figure 1 and the four rollers (9) during false twisting in Figure 1 is extremely rational because the roller (9) is used in combination in the device shown in Figure 2. It becomes.

Further, the fluid-treated yarn is heat-fixed and heated by the heater (7) and spindle (g), but the fluid-treated yarn has a loop structure even in the heating area. As a result, ballooning on the heating side is likely to occur due to large frictional resistance during heating and untwisting of the spinner in the spindle. If this ballooning is too large, processing becomes unstable, but this can be solved by using a balloon prevention guide.

As mentioned above, the device of the present invention can use the i-rake in FIG. 1 as it is as a supply roller for the core yarn by simply providing the twist stopper guide and the balloon prevention guide, thereby greatly reducing the equipment cost. It has the remarkable effect of vines.

Example Zaryester filament yarn was processed using the apparatus shown in FIG. 2 under the following conditions, and a wool-like processed yarn with a loop structure and a crimped structure could be easily obtained.
