Description

Coating Apparatus for Functional Yarn Using Atomization Substance}

The present invention relates to an apparatus for coating to manufacture a functional yarn, and more particularly, to modify the surface of the yarn by plasma treatment in order to impart specific functions such as antibacterial, deodorant, antifouling, flame retardant, and coloring to the yarn, It relates to a yarn coating device for adsorbing a predetermined functional material to the surface of the yarn by microparticles.

As textile products are widely used around daily life, products that exhibit special functions are being released to make them more useful to consumers.By giving the yarn functions such as antibacterial, deodorant, antifouling, and flame retardant, health, safety and hygiene are required. Are used in the field.

The method of imparting functionality to the yarn is largely divided into a method of mixing a composition expressing a specific function in a melted yarn and spinning it through a spinneret (spinning method), and a method of coating a functional composition on the surface of the yarn (coating method). . The spinning method has the advantage of not being easily detached from the yarn because the functional composition is contained inside the yarn, but the coating method is mainly used because the function is not excellent in physical properties as it is mainly expressed on the surface of the yarn in contact with the outside.

As a device for coating the yarn, the Korean Utility Model Registration No. 20-0383281 and Patent Registration No. 10-0752272 have proposed a “coating device for yarn”. The coating device applies a coating solution to the outer peripheral surface of the yarn continuously supplied in one direction. It is provided with an extrusion mechanism such as a die for extruding and applied to the outer peripheral surface of the yarn, and a cooling mechanism for solidifying the coating liquid applied to the yarn by the extrusion mechanism.

However, such a conventional coating apparatus has a complicated structure as a separate die must be provided for each supplied yarn, and a flow path through which the coating liquid flows must be formed in the die. In addition, there is a problem that a lot of time is consumed in drying the applied coating liquid as the coating liquid is applied entirely to the outer peripheral surface of the yarn.

It is preferable that, in the case of the coating chamber 40, it is preferable to install a plurality of zigzag shapes at different heights in the vertical direction. Therefore, the yarn Y transferred into the coating chamber 40 has a long transfer path, so that a sufficient coating time can be secured even if the chamber 40 is formed in a small volume.

The discharge chamber 20 is a space in which a plurality of yarns (Y) supplied from the supply roller 11 to the inside are modified in a sealed state, made of a tunnel-shaped frame, and a plurality of yarns (Y) in a predetermined gas atmosphere. ) By plasma treatment to modify the surface of the yarn (Y). 2 is a detailed configuration diagram of the discharge chamber 20.
