Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a braiding machine for braiding elastic string manufactured with 32 fibers,

More particularly, the present invention relates to a twisted yarn manufacturing apparatus for manufacturing a twenty-four yarn elastic string, and more particularly, to a twisted yarn manufacturing apparatus for producing a yarn having elasticity string, Of course, the present invention relates to a fabricating device for fabricating elastic yarns of 32 yarns, which can prevent the tensile strength from being reduced due to a yarn load even when the yarn is 32 yarns.

In general, a braiding device is a device for producing a knitted fabric (braid: a product made by stringing a yarn using a yarn as a yarn, or having a narrow shape such as a round or a bag-like shape) Also known as a braiding machine.

Such a braid device can be produced for various products such as daily products, decorative articles, industrial articles, fishery articles, medical articles and sports articles, and as a conventional braid device, a decoration line of Korean Patent No. 10-0814007 is formed So-called braided knitted fabric and its braid.

In the conventional knit fabric 3, which is formed by weaving a plurality of knit yarns 2 and 2 'outside the core 1 1' of the inner center, the knit yarn 2 The decorative lines 5 and 5 'formed along the longitudinal direction are formed in the knitted fabric 3 formed of the decorative lines 5 and 5' The present invention has been made in order to improve the decorative property of the knitted fabric and improve the visual aesthetics as well as to improve the binding force of the knitted fabric.

However, the conventional braiding device can be expected to improve the binding force and esthetics when it is in a non-stretchable state such as a normal knitted fabric (for example, a shoelace). However, it is not easy to produce a knitted fabric having stretchability.

This is because, when a check with elasticity is knitted, the tension of the examination must be secured. However, since the conventional braiding device has no means for securing tension, it is impossible to manufacture the knitted fabric with elasticity, .

[0002] Elastic knitted fabrics are mainly used in laports or outdoor clothes and articles (e.g., backpacks and shoes), and particularly in the outdoor market, they are widely applied to outdoor clothes and articles.

Therefore, it is urgent to investigate a braid capable of producing a stretchable knitted fabric, and further development of a braid capable of producing a knitted fabric capable of enhancing aesthetics by ensuring diversity of colors as well as manufacture of stretchable knitted fabrics Is desperately required.

In particular, the manufacture of stretch knitted fabrics with more precise patterns and textures than ever before is becoming increasingly demanded along with the development of the garment industry, which can be implemented based on the advancement of the braiding device.
