ベンゾ１１アゾールとの組合せが、上記目的にかなった
代表的な組合せとして挙げられる。The above ultraviolet absorbers may be used alone, or two or more of these ultraviolet absorbers may be used in combination. At this time, in order to further improve the light fastness, it is necessary to combine ultraviolet absorbers with different maximum absorption wavelengths (λmax) in the ultraviolet region so that they can absorb ultraviolet light over the entire wavelength range.2For example, The combination of 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid with a λmax of 285 nm and 2-(3',5°-di-t-butyl-2''~hydroxyphenyl)5-10lobenzo-11azole with a λmax of 352 nm is These are listed as typical combinations that meet the above objectives.
紫外線吸収剤を繊維に付与するに際しては、紫外線吸収
剤を溶解または乳化した状態で繊維内部に均一に付与す
るようにする。紫外線吸収剤は。When applying the ultraviolet absorber to the fibers, the ultraviolet absorber is dissolved or emulsified and applied uniformly inside the fibers. UV absorbers.

ればよい。In general, many of them are water-insoluble, and even if a UV absorber is dispersed in water and applied to fibers, it cannot be uniformly applied to the inside of the fibers, and the effect of improving light fastness is poor. Therefore, it is necessary to apply the UV absorber to the fibers in a dissolved or emulsified state.1For example, in the case of UV absorbers that are soluble in water-soluble organic solvents such as alcohols, ketones, and polar amides, , it may be applied to the fibers using a water-soluble organic solvent alone or a mixed system of a water-soluble organic solvent and water. In addition, in the case of UV absorbers that are soluble in water-insoluble organic solvents such as aromatic hydrocarbons and ethers, they can be applied to fibers after emulsifying the water-insoluble organic solvent and water using an emulsifier. .

ー法等が挙げられる。さらに、耐光堅牢度を向上させる
ためには、上記方法にて紫外線吸収剤を付与した繊維に
ヒートセットを行うと、より一層好ましい結果が得られ
る。Methods for applying the ultraviolet absorber in a dissolved or emulsified state to the fibers include known exhaust methods, padding methods, spray methods, and the like. Furthermore, in order to improve the light fastness, even more favorable results can be obtained by heat-setting the fibers to which the ultraviolet absorber has been applied by the above method.
紫外線吸収剤の使用量は、繊維重量に対し０．０１〜１
０重量％の範囲が好ましい。使用量が０．０１重量％未
滴の場合、耐光堅牢度の向上効果が乏しく。The amount of ultraviolet absorber used is 0.01 to 1 per fiber weight.
A range of 0% by weight is preferred. When the amount used is 0.01% by weight, the effect of improving light fastness is poor.
また、１０重量％を超える場合、耐光堅牢度の向上効果
が飽和状態に達するばかりでなく、淡黄色を呈した紫外
線吸収剤を用いた場合等には、繊維が淡黄色を呈してし
まい、染色後の色相に悪影響を与えるので注意を要する
。In addition, if the amount exceeds 10% by weight, not only will the effect of improving light fastness reach a saturated state, but also, if a pale yellow ultraviolet absorber is used, the fiber will become pale yellow, resulting in dyeing. Care must be taken as this will have a negative effect on the subsequent hue.

造するものである。It has a configuration in which dyeing is performed after pretreatment of applying an ultraviolet absorber consisting of at least one of a benzotriazole compound and a salicylic acid ester compound,
With this configuration, fibers with excellent light fastness can be produced.
なぜ本発明方法の繊維が高度の耐光堅牢度を有するのか
１本発明者らはその理由について次のように推測してい
る。The reason why the fiber produced by the method of the present invention has a high degree of light fastness is as follows.The present inventors speculate as follows.

寄与している。従来より。The effects of UV absorbers on improving light fastness include ultraviolet shielding, quenching, and radical scavenging, and all of these effects contribute to stabilizing the dye against light. than before.

外線吸収剤を付与し、これを繊維内部に固定しであるの
で、後工程の染色に際して紫外線吸収剤と染料との交換
作用が生じることはなく。A method has been proposed in which an ultraviolet absorber and a dye having such effects are absorbed into the interior of the fiber in the same bath, but the effect of improving light fastness is poor. This is because the molecular weight of UV absorber molecules is smaller than that of dye molecules, and the affinity of UV absorbers for fibers is small. This is thought to be because the UV absorber is replaced with a larger dye, and as a result, a smaller amount of the ultraviolet absorber is incorporated into the fiber. In contrast, in the method of the present invention, an ultraviolet absorber is applied to the fibers before dyeing and is fixed inside the fibers, so that an exchange effect between the ultraviolet absorber and the dye occurs during the subsequent dyeing process. Not.
紫外線吸収剤が繊維内部に均一に取込まれた状態で存在
する結果、優れた耐光堅牢度を発揮するようになるもの
と考えられる。It is thought that as a result of the ultraviolet absorber being uniformly incorporated into the fiber, it exhibits excellent light fastness.
