Description

    The present invention relates to a staining method for staining a chromosome using a pear tree extract.

    Conventionally, various dyes have been used for dyeing a cloth representative as a chromosome, and among them, there is a so-called dyeing of plants which dyes textiles using an extract of plants. The reason for using the plant extract is, for example, to bring out the original scent, color and texture of the plant.

   Among the plant dyeings, for example, a dyeing method using an apple tree is 80 ° to 120 ° C. using an extract obtained by hot water extraction of the xylem, bark, leaves and pulp of a red apple tree. It is dyed to natural fibers and synthetic fibers while being heated frequently.

   This dyeing method focuses on the fact that a certain kind of red apple xylem, bark, leaves and pulp contain a large amount of red pigment, and dyes the fiber with this pigment to achieve robust dyeing. The thing is said to be obtained. (Refer to the abstract of Patent Document 1)

    However, the above-mentioned prior art selects a red apple tree for the purpose of obtaining a robust dyed product, and can only dye colors based on the material of the apple tree. In other words, only limited colors can be obtained from apples.

    In the present invention, a desired dyeing is performed using a pear dye stock solution based on a pear tree material.

    The present invention filters the pear dye stock solution boiled in the first step in which the chip material obtained by crushing the wood part, branches and leaves of the pear tree having a weight of 100 to 400% with respect to the weight of the chromosome is heated and heated in the first step. A second step, a third step of primary staining of the chromosome in the pear dye stock solution taken out in the second step, and a mordant that promotes the fixation of the chromosome in a predetermined amount of water in the chromosome stained in the third step. It consists of a fourth step of immersing in the dye fixing solution formed by addition and a fifth step of drying the chromosome to be dyed in the fourth step.

    The mordant dyes a desired color by combining one or more kinds.

    Bamboo charcoal is poured into the pear dye stock solution taken out in the second step and immersed in for a predetermined time for purification.

    In the third step, the chromosome is preliminarily immersed in an alkaline solution and then stained in a state neutralized with acetic acid.

    The present invention filters the pear dye stock solution boiled in the first step in which the chip material obtained by crushing the wood part, branches and leaves of the pear tree having a weight of 100 to 400% with respect to the weight of the chromosome is heated and heated in the first step. A second step, a third step of primary staining of the chromosome in the pear dye stock solution taken out in the second step, and a mordant that promotes the fixation of the chromosome in a predetermined amount of water in the chromosome stained in the third step. Since it is composed of the fourth step of immersing in the dye fixing solution formed by addition and the fifth step of drying the chromosome dyed in the fourth step, the fabric or paper as the chromosome is dyed in a desired color. Can be applied.

    In particular, due to the effect of the dye fixing liquid, the mordant of the mordant acts on the fluffy fiber such as cotton, and the dye is fixed to the fiber, so that a desired color can be obtained more faithfully.

    And since the said mordant dye | stains to a desired color combining 1 type or multiple types, after determining the dyeing | staining color calculated | required beforehand, the mordant which draws out the desired color is selected. If the desired color is a color that does not exist more naturally, it can be selected from many colors by dyeing a combination of two or three types.

    In addition, since bamboo charcoal is added to the pear dye stock solution taken out in the second step and immersed for a certain period of time for purification, fine solids mixed with the pear dye stock solution and peculiar smell inherent in pear can be removed. . This is effective when the smell of pear does not adhere to the chromosome after staining, and the pear's unique odor is unpleasant.

    In the third step, the chromosome is preliminarily immersed in an alkaline solution and then dyed in a state neutralized with acetic acid. Therefore, after desizing, scouring, and bleaching attached to the chromosome, neutralization is performed. Thus, alkali and acid can be eliminated, and the cause of poor reproducibility and dyeing property of dyeing can be removed.

FIG. 1 is a process showing the work procedure of the dyeing method using the pear tree extract of the present invention.

    An embodiment of the present invention will be described based on the process of FIG. Basically, the first to third steps mainly consisting of the dye solution from the extraction of the pear dye stock solution of the chip material that crushed the wood part, branches and leaves of the pear tree to the primary dyeing, and the addition of the mordant 4th to 5th steps in which dyeing of a desired color is carried out by immersing in the produced dye fixing solution, and a dyed fabric that is neutralized by desizing, scouring, and bleaching the fabric such as fiber or paper to be the chromosome ( Hereinafter, it is comprised of each process of the neutralization process mainly composed of fabric represented by fibers).

    First, the first to third steps will be described.

    In the first step (1), pear dye stock solution is boiled in 2.5 liters of hot water for 30 to 60 minutes with crushing wood parts, branches and leaves of pear trees weighing 100 to 400% of the weight of the cloth. make. The relationship between the weight of the chip material and the weight of the cloth used here is set in order to obtain the base color of the pear material which is the basis for obtaining a desired color at the time of secondary dyeing described later. Therefore, the amount of water of 2.5 liters used here may be about 2.0 liters. In this case, adjustment is performed such as slightly shortening the boiling time because the amount of water is small.

    Next, in the second step (2) following the first step (1), the pear dye stock solution obtained in the first step described above is filtered and filtered with a cloth to remove solid matter such as bark and impurities, and is suitable for dyeing. Use as a stock solution.

    After the second step, 5 ml of a PH stabilizer is added to 1 liter of pear dye stock solution filtered in the second step to adjust and stabilize the pH of the pear dye stock solution (3).

    Thereafter, in the third step (4), the dough is put in a pear dye stock solution having a stable pH and heated at a temperature of 80 to 90 degrees for about 30 minutes to primarily dye the dough. The color dyed in this process becomes a muddy brown color due to the unique color of the pear tree material, making it unsuitable for normal use. However, this color serves as an important stock solution for drawing out a desired color in the process described later.

    Next, before the description of the fourth to fifth steps, the neutralization step (5) of the dough to be prepared at the time of primary dyeing in the third step (4) will be described. In the neutralization process, once the fabric is made alkaline and then acidified and neutralized, the paste is removed from the fabric, scoured, and bleached to improve the reproducibility of dyeing and eliminate the cause of poor dyeing properties. By doing this, the pear dye undiluted solution is permeated into the fabric more deeply.

    The specific explanation is as follows. First, 25 ml of an alkaline agent is added to 1 liter of 80-90 ° C. hot water to make an alkaline solution (6), (7), and the dough is immersed in this alkaline solution for 30-60 minutes while being pulled up. Rinse with hot water. Thereafter, 1 ml of acetic acid is added to 1 liter of hot water heated to 50 ° C. to make an acetic acid solution, and the cloth is dipped therein to be neutralized (8). This process is particularly effective when dyeing cotton fabric, and is performed so that the alkali content of the pear dye stock solution can easily penetrate into the cloth.

    The dough obtained through this neutralization step is primarily dyed in the third step (4) as described above.

    Next, the fourth and fifth steps will be described for secondary dyeing to obtain a desired color by mordanting the fabric. This series of steps begins with the production of a dye fixing solution that becomes the mordant necessary to obtain the desired color, and from among the multiple types of mordants selected to obtain the desired color per liter of water. One or a plurality of these are combined and about 20 ml of mordant solution is mixed to produce a dye fixing solution (10).

    Thereafter, the fabric dyed in the third step (4) in the dye fixing solution is immersed in the fourth step (11) for about 30 minutes to complete the secondary dyeing (12). As shown in FIG. 1, the mordant is dyed in a light brown color of A if the a-type is made of an aluminum liquid, or B-color if the b-type is made of a tin liquid. Dyed in a whitish brown color, if the c-type is due to lime liquid, dyed in a C-reddish brown color, if the d-type is due to titanium liquid, dyed in a D-colored Yamabuki color, e-type If it is based on a copper solution, it is dyed in an E-colored bluish brown color, and if type f is based on an iron solution, it is dyed in an F-colored gray color.

    This is a color that can be dyed experimentally based on the pear dye stock solution obtained in the second step, and a mordant necessary for obtaining a desired color to be dyed is selected in advance. Made possible.

    In the above description, the case where a desired color to be dyed is obtained by selecting one kind of mordant has been described. However, by selecting and mixing two or more kinds of mordants, it does not exist in the natural world other than a to f above. Can be dyed in various colors. After the secondary dyeing, the dyed fabric is washed with water (13), and the dyed fabric is dried in the fifth step (14) to complete all steps.

    Also, after adjusting and stabilizing the PH after the second step (2), about 50 grams of bamboo charcoal (15) is added and immersed for 10 minutes, so that the smell of pear adheres to the dyed fabric. The pear's unique odor will not remain.

    In the present invention, after dyeing on the basis of an undiluted solution of a material of pear, the chromosome is stained as an extract with a dye fixing solution that stains a desired color.
