Description

TECHNICAL FIELD [0001] The present invention relates to a method for dyeing natural dyes using a multicolor dye,

The present invention relates to a method for dyeing natural dyes using multicolor dye, and more particularly, to a dyeing method for dyes of natural dyes using a natural dye harmless to the human body, The present invention relates to a dyeing method of natural dyes using dyes.

Natural dyes are broadly classified into vegetable dyes, animal dyes and mineral dyes, which have been widely used as dyestuffs from ancient times as those which can be obtained naturally. Although natural dyes have many advantages such as a natural color of the dyed material, less adverse effect of the dyed material on the human body as compared with the synthetic dyes, less environmental pollution, and a high cost for wastewater treatment, Due to the limited production of dyes, poor fastness of dyeing, and the possibility of uneven dyeing, the use of synthetic dyes has gradually decreased due to the development of synthetic dyes, which makes it hard to find anything other than a special purpose at present. Furthermore, the dyeing by natural dyes varies depending on various environmental changes such as the origin of the dye, the growth environment, the nutritional status, and the harvesting time, and the color of the dye varies depending on the method of extracting the dye, And industrialization has been sluggish due to many unsuitable aspects in the mass production demanded by modern industries such as.

In particular, the low fastness of dyeing is the most difficult problem to overcome, and it is the biggest obstacle to the modernization of dyeing by natural dyes.

However, recently, due to the development of science and technology and the increase in productivity, the demand for functional products, hygienic products and health-oriented products has increased recently as the textile products are enriched. As a result, it was found that dyes having functional properties among various natural dyes exist.

For example, fabrics dyed with cloves, jojoba, pomegranate, wolfram, and wool were found to be excellent in antibacterial and deodorizing properties (Textile Technology and Industry, Vol. 2, No. 2, 1998).

However, as pointed out above, it is difficult to dye natural dyes simply by impregnating salt solution once with salt solution or by repeatedly impregnating salt solution repeatedly, and it is difficult to dye with natural dyestuff, There was a problem.

In recent years, interest in natural dyes has increased, and a lot of research has been conducted to dye more beautiful colors.

Hereinafter, a method for dyeing natural dyes using polychromatic dye according to preferred embodiments of the present invention (hereinafter, referred to as 'natural dye dyeing method') will be described in detail with reference to the accompanying drawings.

The natural dye dyeing method according to the present invention includes a refining step (S100) for refining a yarn, a natural dye dyeing step (S300) for dyeing the yarn in multicolor, and a dyeing step (S400) for drying the yarn .

Hereinafter, each step will be described in more detail with reference to the drawings.

1 is a flow chart for explaining a natural dye dyeing method according to the present invention. Referring to FIG. 1, the natural dye dyeing method according to the present invention includes a refining step (S100).

The refining step (S100) is performed to remove impurities contained in the yarn and to improve the permeability and dyeability of the yarn, and the yarn is refined at a temperature of 30 DEG C to 40 DEG C using a scouring agent.

As the scouring agent, any one or more of an alkaline activator, an organic solvent, an enzyme, and an oxidizing agent may be used. At this time, the degree of refining can be analyzed by confirming the degree of detection of starch, PVA, acrylic base, wax, and the like.

 2 is a flow chart for explaining an embodiment of a natural dye dyeing method according to the present invention.

Referring to FIG. 2, the natural dye dyeing method according to the present invention may further include a natural dye preparation step (S50).

The natural dye preparation step (S50) is a step of preparing a gardenia extract, a joinery extract, and a fermentation manganese to be used in the natural dye dyeing step before the refining step (S100).

The preparation of the gardenia extract is prepared by mixing 10 to 20 parts by weight of a gardenia powder with 100 parts by weight of water, heating the mixture at 100 ° C for 30 to 50 minutes to produce a gardenia extract, and cooling the gardenia extract to 60 to 70 ° C .

The preparation of the callus extract comprises the steps of mixing 10 to 20 parts by weight of copper with 100 parts by weight of water, heating the mixture at 100 DEG C for 30 to 50 minutes to produce a callus extract, and extracting the callus extract from 60 DEG C to 70 DEG C Cooling process.

The fermentation gums are prepared by preparing conventional fermentation gums, preferably traditional ginseng fermentation gums. The production of such fermentation indices is a technique known in the art, so that a more detailed description is omitted.

Referring to FIG. 2, the natural dye dyeing method according to the present invention may further include a pre-dyeing step (S200).

The mordanting step S200 is a step of previously adsorbing the mordant to the yarn that has passed through the refining step S100. As the mordanting agent, a metallic mordant or an alkaline mordant having an excellent fastness to the dyeing of a multicolor natural dye may be used.

More specifically, as the mordanting agent according to the present invention, an alum (aluminum sulfate potassium) aqueous solution or a soda ash aqueous solution can be used. Here, soda ash is a mordant that is suitable for giving a bright coloring effect suitable for casual wear and children's main colors.

At this time, the alum solution is formed by mixing 0.3 to 0.5 parts by weight of alum based on 100 parts by weight of water. The soda ash solution is formed by mixing 0.3 to 0.5 parts by weight of soda ash on the basis of 100 parts by weight of water.

If alum and soda ash are used in an amount less than 0.3 part by weight, the coloring effect becomes difficult to manifest. If alum and soda ash are used in an amount of more than 0.5 part by weight, a dark coloring effect may be exhibited.

Generally, natural dyes have low fastness, so if they are not mushy, they will not only be lighter in color, but will also gradually change or fall out when exposed to sunlight or washed. However, treating the yarn with a mordant can achieve a deep and deep color and improve the fastness to dyeing. In other words, the mordant agent acts as a link between the low-salt yarn and the natural dye.

On the other hand, the mordanting temperature of this step can be in the range of 60 to 70 캜.

Referring to FIG. 1, a natural dye dyeing method according to the present invention includes a natural dye dyeing step (S300).

The natural dye dyeing step (S300) is a step of dyeing the yarn which has passed through the refining step (S100) or the pre-salt dyeing step (S200) with a gardenia extract, a fermentation gum and a joinery extract, A fermentation section dyeing process for the first portion of the yarn, and a joining extract dyeing process for the second portion of the yarn.

Here, the first portion and the second portion mean a portion existing at another position of the yarn. The first portion and the second portion may be disposed at a distance from each other or may be adjacent to each other.

In this step (S300), each dyeing process is carried out in the order of the step of dyeing the gardenia extract, the step of dyeing the fermented parasite, and the step of dyeing the apical extract. This is because the gardenia extract exhibits yellow color and is used as the background color of the yarn. In addition, when the extract of the present invention is stained on a yarn before the fermentation thereof, the inherent color of the extract of the present invention may be deteriorated due to oxidation of the extract of the present invention.

In the step (S300), the process for dyeing the gardenia extract, the process for dyeing the fermentation gum, and the process for dyeing the gum extract can be carried out by immersing the yarn in the gum extract, the fermentation gum, and the gum extract for about 15 to 25 minutes, respectively.

On the other hand, if the yarn that has passed through the refining step (S100) is directly used without the pre-firing treatment, in this step (S300), a mordant agent is added to each of the groom extract, fermentation goby, , It is preferable to carry out the step of dyeing the callus extract. In other words, raw yarn free yarn proceeds simultaneous mordanting in the natural dye dyeing step (S300).

Referring to FIG. 1, the natural dye dyeing method according to the present invention includes a dyeing step (S400).

The dyeing step (S400) is a step for activating the dye (color spread) of the fermentation goblet and the ginseng extract dyed in the yarn through the natural dye dyeing step (S300). The first part The yarn is dewatered to about 50% so as to cause mildew at the boundary of the second part, and then left at room temperature for 30 minutes or more, preferably 30 minutes to 60 minutes.

At this time, it is preferable that the transferring step (S400) is carried out at a temperature of 30 ° C to 70 ° C. Here, when the temperature of the dyeing step is out of the range of 30 to 70 캜, the development of the color spreading phenomenon is inhibited.

As described above, the present invention includes a dyeing step in order to utilize the dye as a composite advantage in the color composition, but a general dyeing process for dyeing monochromatic dyeing is a method of rapidly diffusing and drying after dyeing in order to prevent dye Lt; / RTI >

In addition, unlike the conventional method of dyeing natural dyes, the present invention provides a sufficient time for dyeing through the dyeing step, thereby giving a high fastness to the multicolored colored dye.

Referring to FIG. 2, the method for dyeing natural dyes according to the present invention includes washing (S500).

The washing step (S500) is a step of removing the dyed dye and the remaining mordant in the dyeing and the dyeing. The yarn passed through the dyeing step (S400) is washed with water or the like.

If the washing is insufficient, the color sharpness of the yarn is lowered after the drying step, and the fastness such as washing fastness and light fastness may be lowered.

Referring to FIG. 2, the natural dye dyeing method according to the present invention includes a drying step (S600).

The drying step S600 is a step of drying the yarn that has passed through the cleaning step S500. The drying temperature is set in consideration of the discoloration of the natural dye, It is preferable to dry for a short time at a temperature range of 180 ° C.

If necessary, this step may be carried out in the shade in order to inhibit the generation of shrinkage and fluff, and to enhance the feel of the dyeing yarn.

FIGS. 3 to 6 are photographs showing the dyeing yarns produced by the natural dye dyeing method according to the present invention.

Referring to FIGS. 3 to 6, the yarn itself has various colors and patterns rather than a fabric made of partially dyed yarn, and the boundaries between the portion where the fermentation indicator is stained through the dye transfer and the portion where the extract of the root extract is dyed are clearly distinguished A gradation effect can be obtained.

In particular, the dyeing yarn of FIG. 3 clearly shows that red and blue colors are formed in each part of the dyeing yarn in a light yellowish background color, and that a transition occurs in the boundary between red and indigo.

These dyed yarns can be used in casual wear and children 's wears where multicolour is mainly used, and can be used as a design advantage of multicolor to help create various designs.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. It can be understood that it is possible.
