Apparatus and method for dyeing waterless precursor using vacuum transfer, and precursor manufactured according to dyeing method

Abstract

The present invention relates to an apparatus and a method for dyeing a waterless precursor using vacuum transfer, and a precursor manufactured according to the dyeing method, in which a precursor is wound around a tub in which a plurality of small holes are formed, and a transfer film coated with a dye of a color to be dyed is covered on the precursor, and then the precursor is subjected to high-temperature heating inside a vacuum chamber while the transfer film is coated with a dye of a color to be dyed. The present invention relates to an anhydrous precursor dyeing method using vacuum transfer, comprising the steps of: (S1) winding a precursor on the outside of a tub, and (S2) applying vacuum pressure to the inside of the tub so that the dye applied to a transfer film can be transferred to the precursor and dyed; (S2) covering a transfer film coated with dye on the outer surface of the precursor wound on the barrel; (S3) heating the precursor in a state in which the precursor and the transfer film are attached to the tub, thereby heating the precursor; and (S4) air is sucked in through the inner space of the barrel, and vacuum pressure is formed through the small holes of the barrel.

Description

technical field [0001] The present invention relates to a device and method for dyeing raw silk into a desired color, and more particularly to an anhydrous raw silk dyeing device and method utilizing vacuum transfer and the raw silk produced according to the dyeing method. It is wound around a barrel formed with a plurality of small holes, and a transfer film coated with a dye of the color to be dyed is covered thereon, and then a vacuum pressure is applied inside the barrel while the inside of the vacuum chamber is heated at a high temperature, Thus, the dye coated on the transfer film can be transferred to the raw yarn and dyed. Background technique [0002] Usually, in order to express various patterns or colors on the fabric, the method of using different colored threads for warp and weft is used, but the problem is that this method of fabric making is to set the pattern or color of the fabric, and it cannot be There are many variations, and in order to obtain an image ...

Problems solved by technology

[0005] However, conventional dyeing devices including the above-mentioned registered utility model use a method of spraying or immersing liquid mixed with dye, so a large amount of pollutants and a large amount of waste water are generated during the dyeing process, and therefore, it takes a lot of money to purify the pollutants. Not only is the economy reduced, but it is also difficult to completely purify, which has a bad impact on the environment.
