SU424366A3 - METHOD OF OPTICAL BLEACHING OF ORGANIC FIBER MATERIALS - Google Patents

Description

one

This invention relates to the theory of bleaching organic fibrous materials, for example textiles, bugs, and cartoons.

A known method of optical bleaching of organic fibrous materials by treating them with an aqueous composition on a basis of arylbiisimide dozole bleaching agent.

However, the effect of bleaching material according to a known method and is sufficiently high.

The purpose of the invention is to increase the effect of bleaching.

This goal is achieved due to the fact that they use bleach of the general formula

Bleaching of the fibrous material is carried out at 30–150 ° C or the material is first plus an aqueous 0.2 --- 0.5% dispersion onTi-iMeiCKoro bleached and heat-treated in a dry, moist atmosphere, and for example steamed at a pressure of 2 atm. heated at 180--220 ° for 30 seconds, washed and dried, according to the proposed method, the material has a high degree of whiteness with a fluorescent fluorescent filter.

 v / v. Example 6. 80 g of cleaved starch are dissolved in 1000 l of hot water (90 °) in 15 minutes. The resulting colony solution is mixed with the elevated temperature obtained with a solution of 5 g of optically bleach 3 in 50 ml of distilled water. The composition, containing starch and optical bleach, has a pH value of 5.5-6.0. This solution covers the surface of the sized paper for printing in the size press; then the treated paper is dried at 50-120 ° in the drying section of the paper machine. Get a paper significantly high whiteness. Instead of glued papers {it is possible to apply lrokleep cardboard with the same result.
