The present invention relates to a method for improving the color fastness of a dyed product obtained by dyeing cellulose fibers or fiber materials made of cellulose fibers and other fibers using reactive dyes or vat dyes. Reactive dyes have shown remarkable growth in usage in recent years due to their excellent color clarity and wet fastness. However, there are two problems regarding the color fastness of dyeings made with reactive dyes. One is acid hydrolysis resistance. During dyeing, reactive dyes form covalent bonds with fibers and form strong bonds; however, over time after dyeing, these bonds undergo hydrolysis and break due to the influence of acids, etc., resulting in moisture loss. This causes the dye to fall off and contaminate other 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. The second problem is the fastness to chlorine. This is a phenomenon in which dyes are oxidized by the action of chlorine contained in the tap water used when washing dyed products, causing fading or discoloration of dyed products. Although treatment with the polyamines developed to date can achieve the purpose of preventing aging,
In many cases, the dye becomes more susceptible to the action of chlorine in tap water, which actually promotes discoloration and fading. Therefore, countermeasures against this problem are required. Regarding the color fastness of dyed products using vat dyes, there is relatively no problem with other fastness properties, but as with reactive dyes, chlorine fastness is low and easily altered by tap water. Causes discoloration. In view of this current situation, the present inventor has developed a method for improving the chlorine fastness of reactive dyes while maintaining various fastness properties such as acid hydrolysis resistance, washing resistance, water resistance, and sweat resistance. In particular, in the case of vat dyes, various studies have been conducted with the aim of improving their chlorine fastness. As a result, it is produced by the condensation of polyethylene polyamine () represented by the general formula NH2- ( CH2CH2NH ) -oH (wherein n is 1 to 5 ) and epihalohydrin ().
It has been found that a polymer having a molar ratio of () to () of 0.5 to 2 has the ability to achieve the above object, and has thereby completed the present invention. That is, the present invention relates to improving the color fastness of a dyed product dyed using a reactive dye or a vat dye, which is characterized by treating the dyed product using the above-mentioned polymer. Regarding improvement methods. The acid hydrolysis resistance of dyed products treated with the polymer of the present invention is excellent, and because the polymer has a high charge density, it is about 1/2 that of conventional processing agents.
It has the advantage of being effective in small amounts. Furthermore, it has extremely good performance in terms of chlorine fastness, and by treatment according to the method of the present invention, it can be improved to such an extent that discoloration and fading due to chlorine is hardly observed. This is in sharp contrast to conventional polyamines, which actually promote discoloration and fading due to chlorine. It also has good performance in terms of fastness to water, fastness to washing, and fastness to sweat. However, in the case of treatment with the polymer of the present invention, discoloration due to treatment may be observed exceptionally with a few dyes such as Leverfix Navy Blue E-RA, but in such cases, the treatment solution PH of 4
This can be prevented by maintaining the following. The method for producing the polymer used in the present invention will be specifically shown in the following reference examples, and it can be obtained by heating the above-mentioned mixture of polyethylene polyamine and epihalohydrin in water or an organic solvent at a temperature in the range of 30 to 100°C. These polymers are easily soluble in water and have a pH of
It is stable as an aqueous solution in all regions of 1 to 14. There are no particular limitations on the method for treating dyed articles using the polymer according to the present invention, and conventionally known methods can be used as appropriate. For example, if the polymer is
The dyed article to be treated may be immersed in an aqueous solution of 0.1 to 2 g for a predetermined period of time, then washed with water and dried. The bath ratio is usually 1:10 to 20, the treatment temperature is usually room temperature to 80°C, and the treatment time is usually 5 to 20 minutes. In order to further clarify the present invention, synthesis examples of polymers used in the present invention are shown below as reference examples, and then examples are shown. Reference Example 1 361 g of ethylenediamine was placed in a reaction vessel equipped with a stirrer, reflux condenser, dropping funnel, and thermometer.
Add 392g of water and stir to dissolve uniformly, then heat to raise the temperature to 50℃. Add 555 g of epichlorohydrin from the dropping funnel to this mixture.
was added dropwise over 2 hours. 30 minutes after finishing dropping, lower the temperature to 80
℃ and react for 3 hours under stirring. It can be seen that the viscosity of the reaction solution gradually increases, and condensation progresses. After the reaction was completed, 10 g of the reaction solution was taken and poured into 500 ml of acetone to produce a white precipitate. The precipitate was filtered through a glass filter and dried under reduced pressure at 60° C. for 24 hours to obtain 6.8 g of a white solid polymer. Yield is 97
It was %. Reference Example 2 In the same manner as Reference Example 1, ethylenediamine 60
g, 139 g of epichlorohydrin was reacted in 200 g of water. After the reaction is complete, take 10g of the reaction solution and use it as reference example 1.
The same treatment as above was carried out to obtain 4.8 g of a white solid polymer. The yield was 98%. Reference Examples 3 to 6 In place of ethylenediamine in Reference Example 1, diethylenetriamine, triethylenetetramine,
In the same manner as in Reference Example 1 using tetraethylenepentamine and pentaethylenehexamine, respectively,
A white solid polymer was obtained by reaction with epichlorohydrin in water. The results are shown in Table 1.

In the case of untreated dyed cotton fabrics, all dyes exhibited discoloration accompanied by significant discoloration, but in the case of dyed cotton fabrics treated with the polymer shown in the reference example, no discoloration or fading was observed, and in the case of vat dyes. It can be seen that it also has good chlorine fastness.
