性糸とから成る繊維製品を実現できる。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a dyed product of a fiber product containing a polyamide fiber, and further relates to a polyamide fiber containing a polyamide fiber and a polyurethane elastic yarn and / or a polyester elastic yarn. The present invention relates to a method for producing a uniform dyed product of a fiber product. 2. Description of the Related Art Polyamide fibers have various excellent properties and are therefore widely used as polyamide fiber-containing fiber products such as fabrics such as knitted fabrics. In particular, it has considerable utility as a foundation / watering fabric. There are various methods for dyeing these cloths. [0003] In the case of polyamide fiber-containing fiber products, in order to stabilize the form of the fabric before dyeing, the temperature must be from 130 ° C to 210 ° C.
At a temperature of 30 seconds to 3 minutes. However, this heat treatment causes a problem that stained spots and stained streaks occur. In other words, there is a defect that the staining property is reduced and stained spots and stained streaks are generated due to variations in heat treatment. [0004] The above drawback is that the heat treatment for stabilizing the fabric form of the polyamide fiber-containing fiber product reduces the amino terminal groups of the polyamide fiber and makes it difficult for the acid dye to be dyed. It seems to be good. [0005] In other words, a report by Ties Karstens et al. Makromo
l. As described in Chem. No. 191 (1990), amino terminal groups in polyamide molecules are reduced by high-temperature heating, and amide bonds in the polymer main chain are cleaved to form aldehyde and ketone carbonyl groups. However, it is known that this reacts with an amino group to form a yellow chromogen. Both the heat-induced reduction of the amino end groups and the hot yellowing result in the consumption of amino end groups, thus resulting in a reduction of the dyeing sites of the acid dyes and consequently of the dyeability. A method for preventing such a decrease in amino terminal group and yellowing by using a semicarbazide compound is disclosed in JP-A-1-229876. Although this method is effective in suppressing the reduction of amino terminal groups and preventing yellowing and consequently maintaining dyeability, some semicarbazide compounds include polyurethane elastic fibers and / or Alternatively, when dyeing a polyamide fiber-containing fiber product containing polyester elastic fiber, some polyurethane elastic fiber and / or polyester elastic fiber may be dissolved or deteriorated. The elastic function to be provided may be impaired. An object of the present invention is to provide not only a fiber product consisting of polyamide fiber alone but also a polyamide fiber-containing fiber product containing a polyurethane elastic fiber and / or a polyester elastic fiber in addition to the polyamide fiber with good levelness and physical properties after dyeing. It is an object of the present invention to provide a method for producing a dyed material capable of keeping the color well. [0010] The present invention relates to a fiber product containing polyamide fiber, which has a formula of 0.05 to 5% owf of the following formula:
A method for producing a dyed product of a fiber product containing a polyamide fiber, comprising applying a polymer of the hindered amine compound monomer represented by (I), performing a dry heat treatment, and then dyeing. [0011] Such a polymer of the hindered amine compound monomer is, for example, a trade name CH from GEBA GEIGY.
Commercially available as IMASSORB 944FL. The polyamide fiber-containing fiber product used in the present invention is not only a knitted and woven fabric made of only polyamide fiber but also a knitted and woven fabric containing polyurethane elastic fiber and / or polyester elastic fiber in addition to polyamide fiber. The polyamide fibers that can be used in the present invention include any well-known polyamide fibers such as nylon 6, nylon 66, and nylon 46, and also include modified cationic dyeable products. [0015] Polyurethane elastic fibers which may be used with the polyamide fibers in the present invention include those known to those skilled in the art, for example, segmented polyurethane having at least 8 fibers of fiber.
It is an elastic yarn occupying 5%, and is a usual ether type or ester type polyurethane elastic yarn. The polyester elastic fiber that can be used together with the polyamide fiber in the present invention can be a polyester elastic fiber known to those skilled in the art, for example, one represented by the following formula (II). Embedded image The polyamide fiber-containing fiber product used according to the present invention may be a fiber product made of a polyamide fiber alone or a polyurethane fiber and / or polyester elastic fiber and formed by a usual cross-knitting method as described above. There can be. The concentration of the polymer of the hindered amine compound monomer represented by the general formula (I) is selected from the range of 0.05 to 5% owf based on the polyamide fiber-containing fiber product. If the concentration used exceeds the above range, the effect may be reduced, which is not economical. On the other hand, when the amount is small, the leveling property is lacking. Specific examples of the method for applying the polymer of the hindered amine compound monomer represented by the general formula (I) include the following: when applying an oil agent during production of a fiber product containing polyamide fibers; when applying an oil agent during false twisting; Can be applied at any time, such as in the pretreatment step of heat setting. Generally, it is preferable to apply the aqueous solution or the aqueous dispersion of the polymer immediately before the step of presetting the polyamide fiber-containing fiber product. Further, as the applying method, an arbitrary method such as an immersion treatment in a liquid, a padding method, a coating method, a printing method, and the like, which are employed in ordinary dyeing, can be used. The dry heat treatment in the present invention is aimed at stabilizing the dimensions of a polyamide fiber-containing fiber product, for example, a fabric, and is carried out at a temperature of 130 ° C. to 210 ° C. as conventionally performed.
The processing is performed for a time of 0 second to 3 minutes, and is usually performed by a setter. The dyeing operation in the present invention can be carried out by using a device such as a winch, a jigger, a beam, a liquid jet dyeing machine, and any of a batch system and a continuous system.
The dyeing temperature at the time of dyeing may be any temperature at which the polyamide fiber is usually dyed, but is generally preferably 80 ° C. or higher. In the dyeing operation of the present invention, the type of dye, dyeing auxiliary, their concentration used, dyeing pH, dyeing bath ratio,
The dyeing time, post-treatment after dyeing, and the like may be any conditions as long as the conditions are the same as those applied to ordinary polyamide fibers, and are appropriately set depending on the type of the object to be dyed and the type of the processing apparatus. In the case where the fiber product comprising the polyamide multifilament and the polyurethane elastic yarn and / or the polyester elastic yarn is a cross-knitted fabric, each of the polyamide multifilament and the polyurethane elastic yarn and / or the polyester elastic yarn is knitted by a knitting machine and a loom. Any of knitted and woven fabrics obtained by supplying to the fabric may be used. The present invention will be described below with reference to examples. However, the present invention is not limited by these examples. The evaluation method used in the present invention is described below. 1. Retention of amino terminal group content of polyamide fiber: After dissolving a polyamide fiber sample in a phenol solution, pH titration was performed with hydrochloric acid, and the amino terminal group amount (m
eq / g) and the retention of the amount of amino terminal groups was determined by the following equation. [Retention of amino terminal group amount (%)] = [amino terminal group amount after dry heat treatment] / [amino terminal group amount before dry heat treatment] × 1
2. Strength retention of fabric: 10 cm × 5 cm of fabric was measured by using Tensilon (manufactured by Toyo BOLDWIN).
The stress at the time of 00% elongation was measured, and the strength retention of the fabric was determined by the following equation. [Strength retention of fabric (%)] = [Strength after dyeing finish]
/ [Stress of greige] × 100 Example 1 40d / 12f nylon filament and 40d / 4f
