本発明は、過酸化水素系の繊維用漂白剤および漂白方法
に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a hydrogen peroxide-based bleaching agent for textiles and a bleaching method.

いことが多い。洗濯に用いた洗剤のうち繊維に沈着して
残ったものが変色して、着色原因となることもある。Almost all natural and synthetic fibers contain some degree of impurity and color even after scouring. Coloring can also occur due to the adhesion of dirt or the decomposition of the fiber itself as a result of use of the textile product. In particular, in the case of worn clothing, sweat stains on the collar, armpits, etc. tend to turn yellow over time. Additionally, yellow stains caused by food deposits often cannot be removed with regular dry cleaning. Detergents used for washing may be deposited on the fibers and remain behind, causing discoloration.

維製品を得るための漂白剤としては、周知のように酸化
漂白剤と還元漂白剤とがあるが、漂白後の復色が少ない
点で、前者の方が有利である。Bleaching agents for eliminating coloration caused by these impurities and decomposition products and obtaining pure white textile products include oxidizing bleaches and reducing bleaches, as is well known, but they are less likely to restore color after bleaching. The former is more advantageous.

うという、極めて繁雑な作業となっている。Hydrogen peroxide, which is one of the oxidative bleaching agents, has become widely used in recent years because it has strong oxidizing power and is easy to treat wastewater. However, the concentration was 35% (wt%
, hereinafter the same) is acidic because phosphoric acid, uric acid, barbituric acid, etc. are added as decomposition inhibitors. Furthermore, when used for bleaching, an alkali such as aqueous ammonia or aqueous sodium hydroxide solution is often added to neutralize the added acid and promote decomposition. Therefore, if residual hydrogen peroxide is left as it is after bleaching, it may damage the fibers, so it is necessary to remove it by rinsing. For this reason, hydrogen peroxide bleaching in the cleaning industry, etc. is done by immersing in hydrogen peroxide water at 60-70'O to which alkali has been added for 5-10 minutes, then rinsing at 60-8000 for 3-5 minutes, then 40- 60°
Do this 3 times: 3 to 5 minutes at C, 3 to 5 minutes at room temperature, and then
The process is extremely complicated, requiring sour (neutralization in an acid bath), gluing, dehydration, drying, and finishing.

いる。On the other hand, low-concentration hydrogen peroxide with a concentration of 10% or less activated with ammonia does not require rinsing after being used for bleaching, but it can be easily exposed to heat, sunlight, or other light containing ultraviolet rays.
Unless an alkali treatment is applied, the oxidation action will not proceed rapidly, and therefore there will be little chance of bad results such as damage to the fibers. Used for bleaching.
本発明の目的は、上述のような現状に鑑み、使用容易な
低濃度過酸化水素水を基剤としながら漂白作用にも優れ
た漂白剤を提供することにある。In view of the above-mentioned current situation, an object of the present invention is to provide a bleaching agent that is easy to use and has an excellent bleaching action, and is based on a low concentration hydrogen peroxide solution.

を加える。The bleaching agent of the present invention can be produced by diluting a commercially available 35% hydrogen peroxide solution with alcohol or alcohol and water. When adding ethylene glycol ethers and/or silicone oil emulsion,
These additional ingredients are added at the same time as or after the dilution.
