Abstract

The present invention relates to a rectangular monofilament yarn and a method of manufacturing the same.

In general, a method of producing monofilament yarn is to make the cross section of the yarn into a circular shape through one drawing and drying process, or to produce a film shape of a large area according to the use, and then cut to a predetermined width to produce a monofilament yarn. Was formed.

However, the conventional monofilament yarn is not smooth surface and bubbles are formed around the yarn, so the strength is easy to be cut off, and the circular monofilament yarn can only be used as a general fabric, so its use is limited. However, since the monofilament yarn produced in the form of film through the general production process requires cutting work made of square fabric after being produced in a wide fabric, the work process is cumbersome and takes a long time, which leads to an increase in production cost. .

In addition, since the monofilament yarn when used outdoors does not withstand UV rays for a long period of time, it is necessary to replace it, and thus, the expense of frequent replacement costs and a large amount of waste generated by the replacement are different.

Description

Rectangular Monofilament Yarn and Manufacturing Method therefor {Production Method And Of A Quadrangle Of Monofilament}

The present invention relates to a rectangular monofilament yarn and a method of manufacturing the same, more specifically, monopropylene based on polypropylene (PP), polyethylene terephthalate (PET), polybutyrene terephthalate (PBT), nylon and the like. The filament yarn is formed to form a square cross section having UV protection and antibacterial function, and the square yarn is wound on each bobbin without twisting or twisting so that the monofilament yarn can be woven into the fabric by a simple weaving process. And it relates to a rectangular monofilament yarn capable of extending the life that can be added by adjusting the content of the sunscreen, if necessary, and a method for manufacturing the same.

In general, a method of producing monofilament yarn is to make a yarn in a circular cross section, or in the case of a yarn used in a sunshade or a rice bag, a yarn in a wide area, and then a sunshade or a rice bag.

On the other hand, when used as a sunshade or rice bag, it is manufactured in a film-like form and cut into a predetermined width to form a yarn and weaving it into a fabric. Therefore, the work takes a long time due to the cumbersome work of cutting and forming a yarn. In addition to the cost increase, there is no wet drawing process in the process, the raw materials are not evenly distributed, so the thickness of the yarn is uneven and bubbles are generated in many parts, which shortens the life span.

In addition, the sunshade used for cultivation of ginseng should be able to withstand strong ultraviolet rays for a long time, but it is weak to the outside and is usually replaced every three years, so replacement cost must be regularly paid. Of course, when used in food bags, such as rice bags, unsanitary discomfort is accompanied by contamination due to bacterial propagation.

Accordingly, the present invention is to solve the above-mentioned problems, the polypropylene (PP), polyethylene terephthalate (polyethylene terephthalate; PET), polybutylene terephthalate (polybuthylene terephthalate (PBT), nylon, etc. as a raw material The monofilament yarn is spun through a rectangular confinement hole formed in a straight nozzle, and then subjected to one wet drawing, two dry drawing, and two drying processes to form a monofilament yarn having a rectangular cross section. It can prevent the cutting, and weaving the yarn as it is without additional cutting work, which can greatly reduce the production cost by simplifying the work process and shortening the working time.

In addition, depending on the use of monofilament yarns such as shoes and industrial materials, UV protection and antimicrobial function can be added to extend the lifespan more than twice, thus reducing the replacement of shading wastes, low manufacturing cost and simplified It is an object of the present invention to provide a rectangular monofilament yarn which can be easily manufactured by a process and a method of manufacturing the same.
