Description

  The present invention is a method of immersing a fabric using lame yarn in a dye solution dissolved with acetic acid and a cationic dye, and performing a dyeing process at the timing of overheating, and a method of dyeing a fabric knitted with lame yarn into a gap It is.

  Conventionally, uneven dyeing is non-uniform dyeing, and thus has received little attention as a product from the viewpoint of dyeing. In particular, there was no such thing as uneven dyeing of lame yarn to make a product, but a large pattern pattern in a knitting weave that does not use lame yarn although the fiber material is different, such as pattern dyeing, blur dyeing, basket dyeing, etc. Pre-existing.

  On the other hand, a method for dyeing a fabric knitted with lame yarn has not yet been proposed. That is, a fabric knitted with lame yarn cannot be dyed, and it cannot be dyed with a decorative appearance, and no dyeing method has been proposed. Therefore, in particular, the fabric knitted with silvery white lame yarn is treated so as to simply maintain the original white silver state.

  Therefore, in order to solve the above-mentioned problems, the present inventor has focused on the ionizing properties of the lame yarn fiber and the basic dye (cationic dye). That is, the molecule of the dye body in the cationic dye is a cation (cation), and the basic group on the surface of the lame yarn or the anion present on the surface of the lame yarn is caused by the electric attractive force (clone force). The present invention was completed by finding a chemical bond.

The present invention is a method for dyeing a fabric knitted with lame yarn into a gap, and is carried out by the following first to sixth steps. That is, the staining method of the present invention comprises:
Nylon that is used in twisted yarns to reinforce lame yarn as a colored finish at the same time that the cationic dye and acetic acid aqueous solution are well mixed in a volume ratio of about 1/3 to 1/4 of the cationic dye to acetic acid aqueous solution. Alternatively, a dye suitable for rayon, in this case a nylon glitter yarn, an acid dye or a cold dye hot dye is prepared. The first step and the second step in which the dye adjusted in the previous period is added when the dye bath reaches about 35 ° C., the mixture is stirred well, and the fabric knitted with lame yarn is added.
Care is taken to prevent the sudden rise in temperature at which the dyebath solution penetrates the fabric evenly by raising the temperature of the dyebath solution more slowly and moving the fabric in the dyebath solution so that it moves and reverses and swings. A third step;
The bath temperature is maintained at 90 ° C. to 95 ° C. for about 15 minutes, and then the heating is stopped, and the fabric is left as it is at a static temperature, or gradually cooled naturally. 4th step In the case of dark finish, 2 bath dyeing is good. In the above 1st step, only the dyeing solution dissolved with the cationic dye and aqueous acetic acid solution is added at about 35 ° C. When the temperature reaches, the temperature is stopped, the fabric is taken out, the bath solution is all discarded, the same amount of water is added, and the acid dye or cold dye hot dye is added as the coloring finish, and the third and fourth steps are performed. . Thereafter, the temperature is further raised and maintained at 85 ° C. to the boiling point for 15 minutes or more. The fifth step comprises the sixth step of stopping the heating of the colored finishing solution in the case of the above-mentioned one bath and of the two baths and allowing the fabric to stand at room temperature while standing in the colored finishing solution. A method of dyeing fabrics knitted with lame yarn into gaps.

  With the dyeing method of the present invention, it has become possible to dye a fabric knitted with lame yarn, which has been extremely difficult, so that it can be developed for the market as a product such as lace knitting or woven fabric. Can be expected, and it can be expected to develop the fashion field. In addition, a fabric knitted with lame yarn dyed in a gap shape is excellent in aesthetics since a plurality of kinds of primary colors can be used for dyeing. As described above, the present invention can provide a dyeing method that can be expected to develop the fashion field. Further, since the dyeing method of the present invention is an economically excellent dyeing method, it is possible to provide a fabric for fashion apparel that is relatively inexpensive and generally available.

  Hereinafter, the present invention will be described in detail. First, as the first step of the dyeing method of the present invention, a cationic dye and an aqueous acetic acid solution are mixed in a volume ratio of the cationic dye to the aqueous acetic acid solution in a range of about 1/3 to 1/4 to prepare a dye bath solution. To do. A predetermined amount of the prepared dyebath solution was used as a dyebath solution. The present invention is a dyeing method in which a fabric using lame yarn is immersed in a dye bath solution in which acetic acid and a cationic dye are dissolved, and the ion concentration varies depending on the temperature and the cationic dye depending on the heating timing.

  In the process of dyeing a fabric using lame yarn, the various ion concentrations of the dye bath change as the temperature rises. That is, anions are generated from the lame yarn, while the cationic dye contains cations. By heating the dye bath, the ion concentration changes based on the physicochemical properties of the lame yarn and the cationic dye. Then, a reaction occurs on the surface of the silver glitter, and the anion generated from the lame yarn side moves to cause a chemical reaction. Accordingly, the dye molecular ion of the cationic dye near the lame yarn is appropriately diffused by chemically reacting with the molecules and / or ions of the lame yarn while diffusing to the surface of the lame yarn or the intermediate layer of the film constituting the lame yarn. It is thought that it is dyed to the place.

  As described above, the fabric using lame yarn and the cationic dye are sensitive to the increase in temperature, and thus need to be prepared in advance. Therefore, after the dye is dissolved in an acetic acid aqueous solution in another small container, an aqueous acetic acid solution of a cationic dye is added. Subsequently, in the case of nylon lame used for twisting yarn to reinforce lame yarn, acid dye or coal dye hot dye is dissolved in warm water and added.

  Next, in the second step of the dyeing method of the present invention, the dye bath solution is heated while stirring the dye bath solution prepared as described above. However, since the dyeing of the fabric knitted with lame yarn starts from around 38 ° C, the fabric knitted with lame yarn must be put into the dyeing solution before the temperature of the dye bath reaches 38 ° C. There is. Therefore, in a state where the temperature of the dye bath is less than 38 ° C., a fabric knitted with lame yarn is put into the dyeing solution, but a fabric knitted with lame yarn is used in the dyeing solution at a temperature up to 35 ° C. It is preferable to input. In addition, when throwing in the cloth, deposits such as glue are removed by washing with water or the like, and the cloth is thrown in after it is completely wetted with water.

  In the third step of the dyeing method of the present invention, the fabric knitted with the lame yarn is moved, reversed, and amplitude in the dye bath solution, so that the dye bath solution penetrates the fabric uniformly, Gently warm the dye bath. When the dye bath reaches about 38 ° C., the fabric charged in the dye bath contains faint signs of coloring. The dyeing texture varies depending on the color and density of the dye. In the third step, the cloth is moved, reversed, and swung in the dyebath so as to allow the dyebath to penetrate into the cloth evenly. Undesirable uneven dyeing may occur, such as stripes that are not dyed in the warp direction of the fibers.

  In the fourth step of the dyeing method of the present invention, the dye bath is gradually heated to about 70 ° C. avoiding a rapid temperature rise and is heated from about 70 ° C. to about 85 ° C. at a stretch. Further, the temperature of the dye bath is increased, and when the temperature of the dye bath reaches the boiling point, the heating is stopped for 15 minutes, and then the fabric is taken out and allowed to stand for about several tens of minutes.

  In the fifth step of the dyeing method of the present invention, two-bath dyeing is good in the case of dark finish. In the first step of a), only the dye solution dissolved with the cationic dye and the acetic acid aqueous solution is about 35 ° C. When the temperature becomes 90 ° C. to 95 ° C., the temperature is stopped and the fabric is taken out and all the bath liquid is discarded. By adding the same amount of water as the discarded amount and adding acid dye or cold dye hot dye as a nylon finish used to reinforce the lame thread, leave it at 85 ° C for about 15 minutes to make two bath dyeing A gap with a slightly darker color is formed.

  In the dyeing method of the present invention, in the case of one bath or two baths, heating of the colored finish liquid may be stopped and the fabric may be left standing in the dye bath solution, or the temperature may be increased. You may take out from a dyebath liquid and process at arbitrary time after several ten minutes progress after stopping. The above is the usual method, but the sentence structure is described above.

[Example 1]
When the fabric knitted with lame yarn was dyed by the dyeing method of the present invention, a fabric dyed in a gap shape could be prepared. This dyed fabric was excellent in aesthetics.

[Comparative Example 1]
A dyebath solution was prepared, and the dyebath solution was heated to such an extent that it did not boil. The temperature was increased rapidly without any particular attention to the temperature control during the temperature increase. With the bath solution heated to some extent, the dye and fabric were added appropriately. As the heating was performed, vertical stripe-shaped color unevenness that was not partially dyed occurred, and peeling phenomenon occurred in some places in the lame yarn constituting the fabric.
