The present invention relates to a method for improving the color fastness of dyed products dyed with reactive dyes. The dyed products dyed using reactive dyes have vivid colors and excellent wet fastness, so in recent years reactive dyes have been increasingly used for dyeing cellulose fibers instead of direct dyes. It's here. However, regarding the color fastness of dyed products using reactive dyes, acid hydrolysis resistance (change over time)
There is a problem. During dyeing, reactive dyes form covalent bonds with fibers to form strong bonds, but over time after dyeing, these bonds are broken due to the influence of acidic substances, resulting in the dye falling off, etc. This appears as contamination on clothing. As a countermeasure to this problem, the dyed product is treated with a dilute aqueous solution of a specific polyamine after dyeing, and this method has been shown to be quite effective. However, with such polyamine treatment,
Even if so-called changes over time can be prevented, the following new problems often arise. (b) The hue of the dyed material changes depending on the treatment. (b) The light fastness of the dyed product decreases due to the treatment. (c) The treatment reduces the chlorine fastness of the dyed product. It is desirable that the dye fixing agent used for the purpose of preventing deterioration over time has the minimum of these adverse effects. The dye fixatives developed to date have any of the above-mentioned drawbacks, in particular, their chlorine fastness is greatly reduced. This problem appears as a phenomenon in which when washing dyed products, the dye is oxidized by the action of chlorine contained in tap water, causing the dyed material to change color or fade. In view of the current situation, the present inventors have conducted intensive research with the aim of developing a dye fixing method that minimizes the above-mentioned disadvantages while maintaining acid hydrolysis resistance. 〓〓〓〓〓
As a result, the expression (wherein R is selected from the group consisting of H and alkyl groups having 1 to 6 carbon atoms, and X is
Cl, Br, NO 3 , 1/2H 2 SO 4 and 1/3H 3 PO 4 , where n is 10 to 10,000) was discovered to have the ability to achieve the above objectives. did. That is, the present invention relates to a method for improving the color fastness of a dyed product dyed using a reactive dye, which comprises treating the dyed product with the polyamine described above. The desired effect can be obtained by using a polyamine having a degree of polymerization (n) within the above range. The acid hydrolysis resistance of dyed products treated using the polyamine of the present invention is excellent, and the original purpose of the dye fixing agent can be fully achieved. Furthermore, there was almost no discoloration, no decrease in light fastness, and almost no decrease in chlorine fastness due to the treatment, and it can be said that the performance was greatly improved compared to conventional polyamine treatment. It also has good performance in terms of fastness to water, fastness to washing, and fastness to perspiration. The polyamine used in the present invention has the formula (In the formula, R is selected from the group consisting of H, an alkyl group having 1 to 6 carbon atoms, and a benzyl group.) It is obtained by polymerizing a salt of a monoallylamine derivative represented by the following and is easily soluble in water. do. For information on the synthesis of these polymers, please refer to BblCOKOMO〓EKY〓〓PHblE COE〓〓HEH
〓〓) Volume 18, page 1957. This method is a method in which monoallylamine is subjected to radiation polymerization by irradiating it with gamma rays in the presence of phosphoric acid. There is no particular limitation on the method of treating dyed products using the polyamine according to the present invention, and conventionally known methods can be used as appropriate. For example, the amount of the polyamine to the fiber is 0.2 to 2.0.
The dyed article to be treated may be immersed in an aqueous solution containing % by weight of the dye for a predetermined period of time, then washed with water and dried.
The bath ratio is usually 1:10 to 20, and the treatment temperature is usually
The temperature is room temperature to 80°C, and the treatment time is usually 5 to 20 minutes. In order to clarify the invention, examples are given of the treatment of dyeings with the polyamines of the invention and the results thereof. Example 1 The polyamine used in this example is as follows. Allylamine phosphate polymer [abbreviated as P (AA)]

The dye used here was Remazol Black B.
[Remazol Black B (product name)], Remazol Golden Yellow G
G (product name)], Leverfits Blue E-3R
[Levafix Blue E-3R (product name)]. Next, the chlorine fastness of this treated dyed fabric was examined using the following two methods. Method 1: PH8.0 containing 100ppm as available chlorine
The test piece was immersed in a buffer solution of ±0.2 (bath ratio 1:
100) and was subjected to a JIS-L-0821 washing tester at 25°C for 2 hours. Thereafter, it was washed under running water for 5 minutes and dehydrated and dried. Method 2: Place the test piece in a household washing machine, and set the inflow rate of tap water (Tokyo) to 6/min at room temperature.
Continuously washed with water for several minutes. The results are shown in Table 3. According to method 1, a remarkable increase in chlorine fastness is observed compared to the untreated dyed fabric. A tendency for the chlorine fastness to increase is also observed in Method 2. This can be treated with a commercially available dye fixative.
This is in contrast to the case where the chlorine fastness is much lower than that of the untreated material.
