Description

Circular knitting machine for Eco-friendly shoes fabric with UV dyeing}

The present invention relates to an environment-friendly shoe fabric manufacturing apparatus applied UV dyeing for manufacturing a cylindrical shoe fabric that can be used in the upper of the shoe using a yarn dyed by the UV dyeing method.

In recent years, global shoe manufacturing companies including Nike, Adidas, New Balance, etc. have been making great efforts to develop and discover eco-friendly materials applicable to shoes in order to protect the natural environment and increase the eco-friendly value of the brand.

In order to cope with many efforts of such a shoe manufacturing company, UV dyeing may be considered to dye shoe fabrics used as shoe uppers using ultraviolet light, not general dyeing.

Here, the general dyeing method widely used in shoe fabrics is to impregnate the yarn by impregnating the dye in the dye solution mixed with the dye, and dyeing the dye by penetrating the yarn. When the dye color is maintained as it is, it is difficult to reproduce.

On the other hand, UV dyeing is a method of dyeing a colored dye resin on the surface of a yarn by curing it with UV rays. The dyeing process is relatively difficult, but there is no waste water generation, no dye leakage, and the resin is heated to a temperature higher than the standard during regeneration. Easily detached, there is an advantage that is not difficult to play.

Utilizing the advantages of the UV dyeing method as it is applied to the shoe fabric as it is expected to reduce the amount of waste water generated, to reduce the emission of toxic components due to the dye and to provide a shoe fabric of eco-friendly materials that can be recycled.

However, the yarn dyed by the UV dyeing method is a form of colored dye resin attached to the surface of the yarn and fixed, so it has a stronger strength and heavier weight than the yarn dyed by the normal dyeing method.

Thus, due to the characteristics of the yarn according to the UV dyeing method, there is a difficulty in manufacturing the shoe fabric using the shoe fabric manufacturing apparatus.

In particular, the bobbin base unit for unwinding and supplying the yarn wound on the bobbin in the shoe fabric manufacturing apparatus, the vertical guide unit for vertically guiding the yarn supplied from the bobbin unit, and the vertically guided yarn vertically Problems occur in the guiding horizontal guide.

In other words, the bobbin mounting part, the vertical guide part and the horizontal guide part do not loosen the yarn smoothly due to the strong strength and heavy weight of the yarn. There is also a problem of poor quality.

Therefore, in order to manufacture high-quality shoe fabrics with the shoe fabric manufacturing apparatus using the yarn dyed by UV dyeing method and apply eco-friendly materials to the shoe fabric without difficulty, the bobbin mounting part and the vertical guide part of the existing shoe fabric manufacturing apparatus having problems Efforts should be made to improve and complement the horizontal guide to have a structure suitable for yarn dyed with UV dyeing.

Republic of Korea Patent Publication No. 10-2011-0136176, published December 21, 2011.
