Description

Detailed Description of the Invention TECHNICAL FIELD OF THE INVENTION

[0001] The present invention is an apparatus for evaluating yarns used in weaving. The yarn used in actual weaving, to which an oil agent or a sizing agent is applied, can be evaluated for abrasion resistance and durability depending on weaving conditions. It relates to a device to be evaluated.

[0002]

Fibers such as polyester and polyamide are used as woven fabrics for clothing and industrial materials.
An oil agent or a sizing agent is added to these fibers in order to prevent them from being damaged by friction with a metal such as a guide at the time of weaving and to impart a bundling property. Therefore, in weaving, it is important to understand the characteristics of the applied oil agent and sizing agent for the yarn to be used, and to understand the wear resistance and durability of the loom.

Conventionally, the characteristics of such a yarn have been evaluated using a tester such as a reed wing movable system or a rotary pin system, but when these testers are used, the yarn to be evaluated is evaluated. Since it is necessary to previously attach an oil agent, a sizing agent, etc., and to dry them, there is a problem that the work becomes complicated. Further, the evaluation contents by these testers are often different from the actual weaving conditions, and it was difficult to apply the obtained data as it is to the weaving.

[0004] In order to solve such problems,
JP-A-63-85159 discloses an evaluation test device having a mechanism similar to the operation of an actual loom. This yarn evaluation and testing device can easily change the operating conditions of the reed, tensor, and the winding device that winds the yarn from the yarn package, so that it can be performed under conditions similar to those of the actual loom. Is what you can do. However,
Since this device is not provided with a device for applying an oil agent or a sizing agent, there has been a problem that it is necessary to previously attach the oil agent or the sizing agent to the yarn to be evaluated and dry it.

That is, the present invention provides a sizing agent application device, an oil application device, and a heat treatment device along a traveling path in which a yarn unwound from a yarn package placed on a yarn supply stand is wound by a winding device via a feed roller. SUMMARY OF THE INVENTION The gist of the present invention is a yarn evaluation device provided with a detachable wear test device, a tension measuring device, and a controller for controlling the operating conditions of each of these devices, the feed roller, and the winding device. .

BEST MODE FOR CARRYING OUT THE INVENTION

The present invention will be described in detail below with reference to the drawings. FIG. 1 is a schematic explanatory view showing an embodiment of a yarn evaluation device of the present invention. The yarn evaluation device of the present invention is a condition for the yarn to be used for weaving along a traveling path in which the yarn unwound from the yarn package 2 placed on the yarn supplying stand 12 is wound by the winding device 11. Is provided with a sizing agent application device 6, an oil application device 7, heat treatment devices 8a and 8b, a detachable wear test device 9, and a tension measuring device 10, which are capable of various changes. A controller 1 for controlling operating conditions is provided.

Next, the yarn evaluation apparatus of the present invention will be described in the order of yarn running. The yarn unwound from the yarn package 2 placed on the yarn supplying stand 12 first passes through the guide 3 and the free roller 13a installed above the yarn package 2, and a constant tension is applied by the tension device 4. Is
The sizing agent is applied by the sizing agent applying device 6 through the feed roller 5a. Subsequently, the yarn is heat-treated by the heat-treatment device 8a, passes through the free roller 13b, and again the feed roller 5a.
Proceed to. Then, the oil agent is applied by the oil agent applying device 7,
After being heat-treated by the heat treatment device 8b via the feed roller 5b, the tension is measured by the free roller 13c and the tension measuring device 10a, and the process proceeds to the wear test device 9. After this, the tension of the yarn is measured again by the tension measuring device 10b, and the feed roller 5
It is wound by the winding device 11 via c.

By continuously performing such a treatment, the wear condition of the reeds and pins of the wear test apparatus 9, the change in tension before and after the yarn is introduced into the wear test apparatus 9, and the sizing agent and the oil agent are applied. By inspecting the condition of the yarn wound after being heat treated, the yarn under various conditions can be evaluated.

In the yarn evaluation device of the present invention, the controller 1 controls the feed rollers 5a to 5c, the winding device 11, and

First, the speeds of the feed rollers 5a to 5c and the winding device 11 can be arbitrarily set by the controller 1, and the feed rollers 5a to 5c and the winding device 11 can be set to 5 to 300 m / min. It is preferable that the speed can be controlled. Further, electric heaters are built in the feed rollers 5a to 5c, and the temperature can be controlled by the controller 1. Depending on the evaluation conditions, it is also possible to adjust the speed and temperature of the feed rollers 5a to 5c and draw the yarn while heat treating the yarn between the rollers.

The drive device of the oil agent applying device 7 and the glue applying device 6 are controlled by the controller 1, and the rotation speed of the oiling roller and the roller of the glue applying device is set arbitrarily by setting the frequency. Can be set to.

The wear test device 9 for checking the durability and wear resistance of a loom or an operating member of a loom needs to be detachable, and a rotating pin system and a reed wing movable system can be selected and used. The controller 1 can control the speed of the wear test device 9. The wear test device 9 of FIG.
