More specifically, it relates to a bleaching property improver for cellulosic fibers that can impart whiter skin, texture, and stitchability that are better than conventional ones even when bleaching baths for cellulosic fibers contain bleaching inhibiting factors such as hardness components. It is.

。This peroxide bleaching is performed by oxidatively decomposing the pigments in cellulose fibers using the nascent acid accumulation generated by the decomposition of hydrogen peroxide, but this oxidative decomposition is
Since it is more efficient to carry out the process in an alkaline environment, an alkaline agent such as caustic soda is used in combination, and sodium silicate is also used as a stabilizer for hydrogen peroxide decomposition under an alkaline environment. Therefore, the bleach solution composition is hydrogen peroxide, alkali (such as caustic soda), and sodium silicate (molar ratio: 5 in2: Na2O = 2.5:
I, etc.). If the water used to bleach cellulose fibers with this product has high hardness, the sodium silicate will combine with the hardness components of the water, resulting in water-insoluble silicate such as calcium silicate and magnesium silicate. Problems arise in that salt is produced and deposited on the fibers, which does not improve the whiteness of the fabric, roughens the texture, and also increases the coefficient of friction with the sewing machine needle, impeding sewing performance. Therefore, a solution to this point was desired. In order to improve this problem, there are cases where ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, hydroxylethylenediaminetriacetic acid, nitrilotriacetic acid, sodium tripolyphosphate, etc. are used in combination. , the effect is not necessarily sufficient,
At present, no fundamental solution to the problem has been reached.

果的でなかった。Further, as a problem in hydrogen peroxide bleaching, there is the problem of embrittlement of cellulose fibers due to contact with metal ions, particularly iron, copper, manganese, etc. During the bleaching process, the decomposition of hydrogen peroxide is accelerated by metal ions (mainly iron ions) and iron rust brought in from the water used or from the equipment, causing hydrogen peroxide to decompose on the cellulose fiber fabric. It has problems such as razor cut marks (scratches that look like they were cut with a razor) or pinholes. In order to improve this problem, attempts have been made to add aminocarboxylate-based organic chelating agents, especially diethylenetriamine pentaacetic acid, but these chelating agents have a negative effect on iron ions in the high vocal range (alkaline side). Since it does not exhibit chelating power, it was not effective in ordinary hydrogen peroxide bleaching carried out in alkaline areas.

との接触を防止しているためであると考えられる。By bleaching cellulose fibers in the coexistence of hydrogen peroxide, alkali, sodium silicate, and the bleaching improver of the present invention, even when the water is highly hard, it is possible to bleach cellulose fibers. Even when metal ions such as iron ions that promote layer separation are included, bleaching of cellulose fibers can impart superior whitening, texture, and stitchability compared to conventional bleaching methods. Although the mechanism by which the problem of poor bleaching is solved by coexisting the bleaching improver of the present invention with hydrogen peroxide, alkali, or sodium silicate is not necessarily clear, the This is thought to be due to its excellent metal ion sequestering ability and dispersion power. That is, when water hardness is high, the bleaching property improver of the present invention chelates hardness components to prevent the formation of water-insoluble substances, and also disperses water-insoluble substances brought in from water and fibers. In addition, when the system contains substances that promote hydrogen peroxide decomposition such as iron ions, the metal ions are chelated and dispersed to prevent contact with the fibers. It is believed that there is.

のレベルには至っていない。As is clear from the results in Table 2, the product containing only hydrogen peroxide, caustic soda, and sodium silicate (A1) has a hard texture and turns white, has poor sewing properties, and has only a small amount of ethylenediaminetetraacetic acid. Even when the comparative formulations (42, 4) were used in combination, there was no significant improvement in bleaching properties.On the other hand, when the bleaching property improver of the present invention was used in combination (5 to 12). So the texture is soft,
It has excellent whitening and sewing properties, and shows good bleaching properties. In addition, the product in which sodium polyacrylate, which is one of the raw materials for the compounded product of the present invention, is used in combination (Ban 3) has a soft texture, whitening, and good sewing properties, but the bleaching tendency f of the present invention is It has not reached the level of a drug.
