SOLUTION: The objective finishing oil application unit comprises a roller and a finishing oil pan in which the roller is partially dipped in the finishing oil and the direction of the finishing oil flow in the pan is allowed to coincide with that of the roller rotation.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for applying oil to elastic fiber yarns.

More specifically, the present invention relates to an elastic fiber yarn applying device which can uniformly apply an oil to the elastic fiber yarn when winding the spun elastic fiber yarn at a high speed.

[0003]

2. Description of the Related Art Conventionally, oil agents have been applied to elastic fiber yarns from the viewpoint of improving quality characteristics such as smoothness, convergence, antistatic properties, and processability and operability.

As a method of applying an oil agent, a method using a roller or a method of spraying an oil agent has been adopted.

[0005]

However, many oils are emulsions containing a surface active agent, an antistatic agent and various other compositions in silicone oil and mineral oil. When performed by a roller, when the oil agent stays in the oil agent pan, the composition in the oil agent is separated or deteriorates, the amount applied to the elastic fiber yarn is not uniform, and the quality variation increases, When high-order processing is performed using such elastic fibers, there is a problem that a high-order defect occurs due to a difference in the amount of oil agent attached.

An object of the present invention is to provide an apparatus for applying an oil agent to an elastic fiber yarn which can uniformly apply an oil agent to the elastic fiber yarn.

[0007]

Means for Solving the Problems The oil applying device for an elastic fiber yarn according to the present invention has the following arrangement to solve the above-mentioned problems.

That is, an oil agent applying device comprising a roller and an oil agent pan in which a part of the roller is immersed in an oil agent,
An oil agent applying device for elastic fiber yarns, wherein a flow direction of an oil agent in an oil agent pan is made to coincide with a rotation direction of the roller.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic perspective view showing an example of the oil applying device of the present invention.

The roller 1 is immersed in the oil agent 3 of the oil agent pan 2 and applies the oil agent adhering to the surface of the roller 1 to the elastic fiber yarn F.

In FIG. 1, reference numeral 4 denotes an oil supply section, and reference numeral 5 denotes an oil discharge section.

In the present invention, the flow direction of the oil agent in the oil agent pan coincides with the rotation direction of the roller.

To match the flow direction of the oil agent means to make the direction of the oil agent flow in the oil agent pan substantially parallel to the rotation direction of the roller.

That is, the flow direction is made to coincide with the direction perpendicular to the rotation center of the roller.

If the flow direction of the oil agent does not coincide with the rotation direction of the rollers in the oil agent pan, the oil agent will accumulate in the oil agent pan, and quality deterioration such as separation of the accumulated oil agent over time cannot be avoided. There is.

In the production of elastic fibers, usually, a spinning machine having a plurality of weights is used, and it is preferable that an oiling device is provided for each weight.

The weight in the present invention means that the polymer discharged from one spinneret is heated and / or
After cooling to form a single yarn, it is preferable to collectively refer to a plurality of yarns formed from a composite yarn or a twisted yarn formed by twisting one or more single yarns. Alternatively, a composite yarn or a single twisted yarn formed by twisting a plurality of single yarns may be collectively referred to as a weight.

The supply of the oil agent to the plurality of weights is performed, for example, as shown in FIG.
As shown in (1), a circuit is formed so that oil can be circulated from the oil storage tank 6 by using the pump 7, and a number of supply paths corresponding to the weight are branched from the circuit, and each supply path is provided with the oil agent of the present invention. This can be performed by connecting the device to the device and transferring the oil in the oil storage tank to the oil applying device.

For the purpose of adjusting the amount of oil supply to each oil supply device, it is preferable to use a flow control device such as a valve at least upstream or downstream of the oil supply.

The oil agent provided in the present invention may be any oil agent such as a silicone oil agent or mineral oil, as long as it can be used for an elastic yarn. What mixed the composition according to is preferable.

Further, as the elastic yarn in the present invention, a polyurethane-based elastic fiber, a polyether / ester-based elastic fiber or the like is preferable.

Such an elastic yarn can be manufactured by dry spinning, melt spinning, or the like. The polymer discharged from the die is cooled to form a yarn, and can be applied with an oil agent and wound around a bobbin or the like. .

[0024]

According to the present invention, the amount of the oil agent applied to the elastic fiber yarn can be made uniform, and the quality variation can be reduced.
When high-order processing is performed using such elastic fibers, high-order defects due to differences in the amount of oil agent attached can be significantly reduced.
