Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a multi-

The present invention relates to a multipurpose composite cord and a manufacturing method thereof. More specifically, it can be used for various purposes such as bracelets, necklaces, bag straps, shoelaces, ribbons, belts, and sandal bands according to the user's preferences. In addition, it has high tensile strength, elasticity, The present invention relates to a composite cord and a manufacturing method thereof.

Generally, a string used for a bracelet, a necklace, a bag strap, a shoestring, a ribbon, a belt, and a sandal band has various uses as its own. In addition, a strap having two or more strands is twisted, Or the band is formed by weaving the string in various forms with other linear materials, or they are woven in the form of a woven fabric to form a cloth.

In recent years, a composite cord capable of exhibiting the advantages of a leather strap at an inexpensive value has been developed and partially used. This is a synthetic resin sheet having a high tensile strength (very low elasticity) coated with a narrow synthetic resin sheet , It can be manufactured in various forms because of its excellent shape and color feel, but it can not have the same texture as leather strap (moderate volume and cushioning property). Therefore, the article manufactured using such a composite strap is rigid, There is a problem that the contact property with the skin and the skin affinity are poor.

Accordingly, Korean Patent Registration No. 20-0395696 has registered a patent concerning the 'synthetic leather composite cord'. Specifically,

(a) two synthetic leather materials having one or more circular cross-section linear cores having low elongation and high toughness, and (b) long strip shapes capable of wrapping the core, And the above-mentioned objects are respectively folded inwardly at both ends thereof, and the core material is positioned between the above-mentioned objects, and these materials are mutually adhered to each other. There is a bar.

However, in the case of a synthetic leather having poor flexibility such as natural leather, both ends of the object are not smoothly folded, and when used on a shoelace, if friction continues due to frequent movement, the outer surface of the string is loosened, There is a problem that foreign matter such as dust or the like is interposed between the joining end faces to give an aversion to the appearance.
