Description: BACKGROUND OF THE INVENTION [0002] Fiber dyeing can be said to be simple draw dyeing, which is strongly related to traditional drawing techniques. The first point of non-uniform dyeing is that "parts to be dyed" and "parts not to be dyed" are separately dyed by physical prevention. For the method, various anti-staining methods have been devised. The second point is the staining method.
After being physically dyed, it is colored by dip dyeing or pouring. In the dip dyeing method, a single dyeing process results in a single color, and it is necessary to repeat the process when dyeing in multiple colors. The method of dyeing by pouring can be dyed separately, and can be dyed in shades and in multiple colors. Shading with indigo dyeing has been practiced since ancient times. [0004] The "deep color dyeing using reactive dyes" injection method can be dyed simply by pouring a dyeing solution, so that the process is short. Dyes applied to this dyeing are vat dyes, reactive dyes, naphthol dyes, and sulfur dyes. At present, most cellulosic dyeings use reactive dyes. The reason is excellent dyeing fastness and abundance of hues, and it is necessary to dye with a reactive dye even in uneven dyeing. In the case of spot dyeing using reactive dyes, medium and light colors are possible, but dark colors are difficult. [0005] When the conventional method of "sharp uneven dyeing" is applied to cotton knit, coarse cloth, etc., "bleeding" is not sharp and sharp lines are not formed. "Bleed" of knit and coarse fabric
In order to prevent blemishes and to achieve shaved uneven dyeing, it is possible to solve the problem by pasting the fabric in advance. However, when the cloth is pasted and pasted, the dyeing concentration is greatly reduced. [Problems of the printing method] To prevent the density reduction and the "bleeding", the printing process of "color gluing" → "steam fixing" can be solved. If dyeing is carried out by this method, the image can be achieved although the image of uneven dyeing is different. But,
In factories that do not have a steaming device and mainly use dyeing, new capital investment is required, and it is difficult to manufacture because of a heavy burden. The challenge here is the development of the "uneven dyeing method using reactive dyes" that does not require steaming heat treatment. [0007] It is a well-known fact that "uneven dyeing of reactive dyes with alkali glue" adheres the dyes to the fabric even at normal temperature, and after drying, the dyes adhere to the alkaline solution and are fixed. It is. Conversely, the dye adheres to the fabric to which the alkali has been adhered even when the dye solution is left standing. This property was applied to uneven dyeing to provide a fixing means without performing steaming heat treatment. As a concrete means, (1) glue is added to an alkaline solution to prepare an alkali glue for uneven dyeing. (2) An alkaline paste is applied to the cloth for the purpose of preventing "bleeding" and fixing. (3) Excess glue is removed with a dehydrator or the like, and "wrinkles" are applied to partially prevent dyeing. (4) Adhere the reactive dye solution to the fabric. (5) Leave for the time required for fixing. (6) After fixing the dye, the paste is removed by water washing, neutralized, and soaping is performed to remove the unfixed dye. By the “method for dyeing unevenness of reactive dye with alkaline paste” performed in the above steps, uneven dyeing with sharp reactive dye without performing steaming treatment was obtained. The present invention is carried out in the following steps. (1) An alkali-containing paste is adhered to a cloth. (2) Create wrinkles. (3) Deposit the reactive dye. (4) Leave for the time required for fixing. (5) Perform soaping. [0009] The alkaline composition of the alkaline paste was combined from sodium hydroxide, sodium carbonate, potassium carbonate and sodium silicate. The printing paste was used as the paste. A sizing agent that does not react with the reactive dye and is stable against alkali is desirable. For example, highly etherified cellulose derivatives are alkali-stable without reacting with reactive dyes. Many of the processed starch-based sizing agents have good alkali stability, and some sizing agents are not easily reacted with the reactive dye. Sodium alginate used for the reactive dye is not stable to alkali, but can be used by adjusting it at the time of use. Other,
There are many sizing agents that can be used because the dye and glue are not in the same liquid but come into contact on the fiber for the first time. The following is a prescription example. Here, the amount of the paste is adjusted according to the sharpness of the target uneven dyeing and the density of the cloth. The more glue, the sharper the image. The fixing time of the alkali varies depending on the combination. When the alkali is relatively weakened, the fixing time is prolonged, and when it is strong, it is shortened. After the alkaline glue is adhered to the fabric, the excess glue is removed by a dehydrator or mangle and "wrinkles" are formed. Depending on the purpose, the way of "wrinkling" is changed depending on the direction, density, strength and strength, and the degree of anti-staining is adjusted. Before the alkali paste is dried, coloring is performed with a reactive dye. There are many types of reactive dyes,
Each has a different reactive group. At the standard alkali strength (fixing time: 1 to 2 hours, pH 12 to 14) shown in the examples, the relatively low-reactivity (dyeing: high temperature type) reactive dye was not dyed at a high concentration. . In addition, many of the dyes obtained at a high concentration were of a medium temperature type, and particularly a high concentration of a polyfunctional type was observed. The coloring method is free, such as applying with a brush, a brush or an air spray, drawing a pattern by pouring a dye solution with a raindrop, a ladle or a beaker, and the number of colors is not limited. After coloring, it is left as it is to fix it. The fixing time depends on the type of dye attached to the fabric and the alkali. However, if the time is long, the production efficiency decreases, and if the time is short, a hue difference or a density difference occurs in the first half and the second half of coloring. Time is suitable. In the post-treatment, the paste is sufficiently removed by washing with water, neutralized with an acid such as acetic acid, and then heated with hot water (70%) containing a surfactant.
(95 ° C. to 95 ° C.). The target fibers are cellulosic fibers such as cotton, hemp, rayon and silk, which can be dyed with a reactive dye by alkali fixation. Example 1 (1) The following alkali-containing glue is adhered to a cotton knit fabric and a T-shirt, and excess glue is removed by a dewatering machine. (2) Cause wrinkles (3) Adhere multifunctional reactive dye (4) Leave for 1 hour (fixing time) (5) Wash, neutralize and soap Example 2 (1) The following alkali-containing glue is adhered to rayon ground, and excess glue is removed by a dehydrator. (2) Cause wrinkles (3) A vinyl sulfone-type reactive dye is attached (4) Leave for 2 hours (fixing time) (5) Wash, neutralize and soap Example 3 (1) The following alkali-containing paste is adhered to silk cloth, and excess paste is removed by a dehydrator. (2) Causes wrinkles (3) Adheres a reactive dye having a dichloroquinoxaline group (4) Leave for 4 hours (fixing time) (5) Wash, neutralize and soap According to the present invention, it is possible to perform sharp uneven dyeing on a knitted fabric or the like by using a reactive dye, and at the same time, to shorten the process without capital investment and improve the productivity. is there. The present invention is characterized in that bleeding prevention and fixation are performed in one step, and after applying the reactive dye solution, it is only necessary to take an appropriate leaving time, and it is possible to produce it at the current dyeing factory mainly for dyeing. Highly efficient "uneven dyeing method"
It is. In addition, according to this uneven dyeing method, since the image of the original fabric can be reduced in size as a whole, multicolor coloring can be performed at an approximate position, and the coloring method can be reflected.
