The field of engineering

The technical solution concerns the smile with sorption properties with active carbon active.

The current state of the art »

Active carbon fibers have long been known for their sorption and desorption properties. These properties can be suitably regulated by means of motivation, warmth, length of action and activators. Ιή

You can compare activated carbon with suitably activated carbon:

Fibers have a much greater sorption capacity and

Achieve sorption and desorption speed. Active

Especially in the interface, the active carbon fibers thread, loosen, dust and contaminate the environment «

Somewhat better results are achieved with an active carbon textile, which is a woven, knitted fabric or also a weave made of non-woven textile). Flat structures made of active carbon fibers should have solidified all edges by? not to thread and not stretch, which in most cases is not feasible. A belt of an active carbon part with solidified edges is usually used for the production of the fabric, which is cut transversely onto individual pieces in the desired size, in which the cutting point is then disactivated carbon testile, stretches, separates and hurry up carbon fiber »crumble and dust. This means that the application is only limited to those purposes where the listed slopes are not an obstacle.

The essence of the quenching solution,

The task of the technical solution is to eliminate the mentioned slopes1 to the greatest extent and to make greater use of them in the area of filtration of hygiene and medical science. According to the technical solution, this is achieved by the fabric with scrambling capabilities, the essence of which is AT 000 048 Ul 3arin, that it consists of at least one surface image of afe "ii.v & n carbon fibers, which ??" is fixed on a 'tragedy pad', it is requested for the protection of the ~ 1 surface area of the distribution if the F5. see Gebi Ide made of active carbon fibers from the functional side with a protective layer fixed on the TV base. is provided, it is advantageous if the increased hicRe of the
