With this purpose, concentrated solutions are diluted with water so that the resulting solutions for processing, which may be added the usual excipients, have the target concentrations of the fluorescent optical Brightener.

Textile fibers suitable for bleaching, are textile fibres of synthetic materials, for example polyamide, semi-synthetic materials such as regenerated cellulose, as well as from natural Mat is rials, for example wool or cotton, as well as the blend of fibers, for example of the complex polyester/cotton, and method conventional in the textile industry, natural fibers can also be provided with apertures.

Textile materials, which were designed for whitening may be in various States of processing (raw materials, semi-finished products or finished products). Fibrous material can be, for example, in the form of staple fibers, wool waste when cutting or varovanie fabric, skeins of textile fibers, yarns, twisted yarns, non-woven fibrous materials, felts, procesov, teasing products, textile composites or jerseys, but preferably in the form of woven textile materials.

Their treatment is carried out using dilute solutions in accordance with the invention, optionally after the addition of dispersing agents, stabilizers, wetting agents and auxiliary substances. Depending on the dissolved fluorescent optical Brightener may be advantageous to conduct the process in an acid, alkaline or preferably neutral bath. The treatment is usually carried out at temperatures of from about 20 to 140°C., in particular at the boiling point of the bath or so (about 90°C).

In the bath you can add the following excipients:

Dilution of concentrated solutions of fluorescent optical brighteners in accordance with the invention for the preparation of the respective finishing baths carried out in such a way that, when considering the material to be impregnated, it absorbs fluorescent optical Brightener in an amount of at least of 0.0001 wt.%, but at most 2 wt.%, preferably from 0.0005 to 0.5 wt.%. The necessary concentration set in a simple way by the values of the dependent module is provided for use finishing baths, the nature of the processed material and the dissolved fluorescent optical Brightener.

actuary in accordance with the invention can also be added to baths for washing or detergent compositions. While in the bath for washing simply add the solution in an amount which contains the target number of fluorescent optical Brightener. Solutions in accordance with the invention can be added to the detergent composition at any stage of the cooking process, for example in the slurry before spray washing powder or during the cooking liquid detergent compositions.
