The present invention relates to a method for treating a fiber sheet containing an elastomer, and more particularly, to a method for improving the color fastness of a fibrous sheet comprising polyamide fibers and an elastomer. Conventionally, the treatment method after dyeing polyamide fibers with acid dyes is to treat them with a tannic acid bath.
Subsequently, a method of treatment with tartarite or a method of treatment in a bath containing a synthetic tannic acid compound is adopted. However, even if a fiber sheet made of polyamide synthetic fiber and polymeric elastomer is dyed with an acid dye and then subjected to a dye fixation treatment using conventional methods, a satisfactory dye fixation effect cannot be obtained. Washing fastness is extremely poor. Furthermore, when conventional polyamide synthetic fibers are dyed with metal complex dyes, they have satisfactory color fastness, so dye fixing treatment is not generally carried out after dyeing. However, in the case of fiber sheets made of polyamide synthetic fibers and polymeric elastomers, satisfactory color fastness cannot be obtained even when dyed with such metal complex dyes. When dyeing such a fiber sheet with an acid dye or a metal complex dye, the adsorption rate of the acid dye or the metal complex dye to the polymeric elastomer is faster than that to the polyamide fiber component in the low temperature region of the dyeing process, and Once the dye has been adsorbed to the polymeric elastomer component, it does not easily transfer to the polyamide fiber component even if the dye reaches a high temperature range necessary for dyeing the polyamide fiber component. Thus,
When the predetermined dyeing process is completed, the amount of acid dye or metal complex dye dyed on the polymeric elastomer component is equal to or larger than that on the polyamide fiber component. Even if such a dyed sheet is subjected to a dye fixation treatment using a synthetic tannic acid compound or the like, fixation between the polyamide fiber component and the dye is achieved, but the fixation effect between the polymer elastomer component and the dye is extremely weak.
Each time the sheet is washed with water or washed repeatedly, the dye adsorbed to the polymeric elastomer component falls off without limit, resulting in a deterioration in the color fastness of the dyed sheet. The inventors of the present invention conducted extensive research to solve these problems, and as a result, they discovered an effective means for improving color fastness. That is, after dyeing a polyamide fiber sheet containing a polymeric elastomer with an acid dye or a metal complex dye, the dye dyed on the polyamide fiber component is fixed under specific conditions, and then an anionic surfactant and a nonionic dye are dyed. Colorfastness is improved by removing most of the dye adsorbed to the polymer elastomer component by treatment with a bath containing at least one surfactant selected from surfactants and amphoteric surfactants. Obtain a dyed sheet with good quality. The gist of the present invention is to dye a fiber sheet made of polyamide fibers and a polymeric elastomer with an acid dye or a metal complex dye, and then fix the dye to the polyamide fiber component using a synthetic tannin dye fixing agent. This is a dyeing treatment method for a fiber sheet containing a polymeric elastomer, which is characterized in that most of the dye adsorbed to the polymeric elastomer component is subsequently removed using a surfactant. The effects of the present invention can only be obtained by performing treatment with a surfactant after treatment with a synthetic tannin-based dye fixing agent after dyeing. Good effects cannot be obtained by reversing the order of both treatments or by performing only one treatment. Next, the content of the present invention will be explained in detail. The fiber sheet to be dyed in the present invention is made of polyamide fibers and polymeric elastic material. Here, the polyamide fibers include nylon 6, nylon 66, nylon 11, nylon 610, aromatic polyamide, and modified fibers thereof. Examples of the polymeric elastomer include urethane-based, acrylic-based, silicone-based, and fluorine-based resins. In particular, polyurethane-based resins include various polyether-based, polyester-based, and polyetherester-based resins. long chain diols (polyester or polyether), diisoacetate,
and those obtained by reaction with low molecular weight chain extenders (glycols, diamines, etc.). The polymer elastomer content of the polymer elastomer-containing sheet is in the range of 3 to 90 wt%, but the effect of the present invention is more pronounced as the polymer elastomer content increases. Examples of acidic dyes according to the present invention include leveling acid dyes, half-leveling acid dyes, milling acid dyes, and examples of metal complex dyes include 1:1 type and 1:2 type metal complex dyes. For example, milling acid dyes and 1:2 type metal complex dyes are particularly effective. Dye fixation treatments for polyamide fiber components include a two-bath process in which the dye is treated with tannic acid and then treated with tartar stone, and a one-bath process in which synthetic tannic acid is used as a fixing agent. A fixing method using a one-bath process is preferable because of the problems of labor and time caused by the two-bath process and problems with texture hardening. Examples of synthetic tannic acids include polyhydric phenolsulfonic acid derivatives, aromatic polymer derivatives, polyhydric phenol derivatives, and oxyfuric acid salt condensates. The dye fixation treatment on the polyamide fiber component of the polymer elastomer-containing fiber sheet is preferably carried out under the following conditions regardless of the dyeing density. That is, the concentration of the dye fixing agent is 3 to 10% based on the weight of the polymeric elastomer-containing fiber sheet, the treatment temperature is 70° C. or higher, and the treatment time is 20 to 60 minutes. As the surfactant, it is preferable to use one or more selected from among anionic, nonionic, and amphoteric surfactants. In particular, nonionic and amphoteric surfactants exhibit excellent effects. The concentration of the surfactant used is 2 to 3% based on the weight of the polymer elastomer-containing fiber sheet, and the processing temperature is 50 to 80℃.
°C and treatment time of 20-60 minutes is recommended. After treatment with such a surfactant, washing with water is performed. According to the present invention, a fiber sheet containing a polymeric elastomer with extremely excellent fastness and a high commercial price can be obtained. The present invention will be specifically explained below with reference to Examples, but is not limited to these in any way. Example 1 A suede-like artificial leather gray fabric made of 75% nylon fiber with a single yarn fineness of 0.05 denier and 25% polyurethane was placed in a jet dyeing machine at a water temperature of 30°C and dyed using the following dyeing methods. , and treatment (bath ratio 1:20). Method (method of the present invention) The following dyeing aids and dyes (1) to (3) were added in order. (1) Albegal A [Level dyeing agent manufactured by Ciba-Geigy]

After that, it was washed with hot water and water, taken out from the dyeing machine, and dried. Method (Comparative Example 1) In the method, treatment with a surfactant was not performed after the dye fixing treatment. Method (Comparative Example 2) After dyeing with a metal complex dye, the material is first treated with a surfactant and then subjected to a dye fixing treatment. Table 1 shows the K/S and washing fastness results of the dyed products dyed by the above method.

かつた。[Table] K/S is a value indicating the color density determined from the reflectance (R) by the Kubelka-Munk function, and is determined from the following general formula. K/S=[1-R] 2 /2R (R: reflectance taking a value of 0 to 1) The higher this value is, the darker the color is, and the lower this value is, the lighter the color is. Fastness determination is based on 61− specified in the AATCC Law.
Started in 1965. From this result, the method of the present invention has a dye concentration of 10
Despite the deep color of %owf, the washing fastness was very good, and compared to the method of Comparative Example 1 in which no surfactant treatment was performed, the fastness was significantly improved. In addition, in Comparative Example 2, since the dye was treated with a surfactant before fixation, the dye fell off both from the polymer elastic body and from the fiber side, and the dyed fabric became extremely light in color with K/S of 14.8, and the color fastness was also low. No improvement was observed.
