Problems solved by technology

[0004] However, due to the limited production of natural dyes, unsatisfactory fastness of dyed products and easy staining, the use of natural dyes has gradually decreased with the development of synthetic dyes, until now there are almost no other uses except special uses
The content of pigment components in natural dyes changes according to various environmental changes such as the place of origin, growth environment, nutritional status, and harvest time, and the color of the dyed product also changes according to the extraction method of the pigment, dyeing method, etc., so there are many aspects that are not suitable. The mass production required by modern industry, which is one of the causes of sluggish industrialization
In particular, in natural dyeing, low fastness of dyed matter is the most difficult problem to overcome, which has become a major obstacle in the modernization of dyeing technology with natural dyes

Embodiment 1

[0109] Example 1: Preparation of Naturally Dyed Fabric Using Dioscorea

[0110] (1) The basis weight was 52g / m2 prepared as a fabric 2 silk fabric.

[0111] (2) A dyeing process in which the prepared fabric was immersed in the Dioscorea japonica extract prepared in Preparation Example 1 for 1 hour, the immersed fabric was taken out, and then the fabric was completely dried in a natural state was performed, and the dyeing process was repeated 30 times.

[0112] (3) A color development process of immersing the dyed fabric in the mixed solution at 28° C. for 10 minutes, taking out the immersed fabric, and then completely drying the fabric in a natural state, and repeating the first color development process 6 times . At this time, the mixed solution was prepared by mixing the Dioscorea japonica extract prepared in Preparation Example 1 and water at a weight ratio of 1:1.2.

[0113] (4) The sludge is evenly coated on one side of the fabric that has undergone a color development...

Embodiment 2

[0116] Example 2: Preparation of Naturally Dyed Fabric Using Dioscorea

[0117] Naturally dyed fabrics were prepared in the same manner as in Example 1. However, the difference from Example 1 is that when the dyeing process is performed, the dyeing process is not repeated 30 times, but the dyeing process is repeated 10 times.

Embodiment 3

[0118] Example 3: Preparation of Naturally Dyed Fabric Using Dioscorea

[0119] Naturally dyed fabrics were prepared in the same manner as in Example 1. However, the difference from Example 1 is that when the dyeing process is performed, instead of repeating the dyeing process 30 times, the dyeing process is repeated 50 times.

Abstract

The present invention relates to a natural dyeing method using Dioscorea cirrhosa, and more particularly, to a natural dyeing method using Dioscorea cirrhosa, in which a naturally dyed fabric does not discolor, is harmless to a human body, has excellent color rendering properties, antibacterial properties and deodorization rates, and has excellent color fastness such as crockfastness and light fastness.

Description

technical field [0001] The present invention relates to a natural dyeing method using yam, and more particularly, to a natural dyed fabric that does not change color, is harmless to human body, and has excellent color rendering, antibacterial and deodorizing rates, and is fast to rubbing. Natural dyeing method using diosca Background technique [0002] Generally, natural dyeing refers to the working process of coloring fabrics using plant, animal or mineral dyes. Compared with chemical dyes, this natural dyeing is characterized by low color chroma, environmental protection, and many human-friendly elements. [0003] Compared with synthetic dyeing, such natural dyeing has the advantages of natural color, excellent aesthetics, and functions such as antibacterial, deodorizing, and antiallergic properties due to natural dyeing by processing natural materials into dyes. In addition, natural dyes are advantageous in that they do not cause waste water and odor problems that occur...
