  • Distribution profiles within a fabric It can be produced in different degrees of absorption and subtleties. Compared to conventional superabsorbent fibers of polyacrylates, SAF are less brittle and brittle, and are therefore ideal for forming fabrics and nonwovens.
  • the SAF are not present in a three-dimensional random array (as is generally the case with nonwovens), but aligned two-dimensionally are (ie only distributed in one plane) or completely one-dimensionally aligned (i.e., all fibers point in the same direction).
  • Wounds with said SAF preferably have an SAF content of about 25% by weight.

  • Luquafleece hides a superabsorbent fleece material consisting of a polyester nonwoven treated with superabsorbent polymers, which can be used for active moisture regulation. Above all, Luquafleece is characterized by an outstanding absorption capacity of aqueous solutions and water vapor.
  • Luquafleece consists of a polyester nonwoven treated with polyacrylic acid superabsorbents.
  • the Luquafleece technology is characterized by a strong immobilization of the superabsorbent on the fiber, whereby high loadings of superabsorbent polymers and good abrasion properties can be achieved.
  • Luquafleece is based on a reversible mechanism. Thus, the performance is also fully maintained over a longer period of use. Therefore, Luquafleece is also suitable for multiple use.

  • Aerogels are highly porous solids in which up to 95% of the volume consists of pores. There are several types of aerogels, with silicate-based ones being the most common. Other forms, such as plastic or carbon based, may be of importance for specialty applications. In principle, one can use any metal oxide, polymer and various other substances as a starting point for the airgel synthesis by means of a sol-gel process.

Also possible are perforation points (small openings whose edges are compressed by applying pressure and temperature). In addition, few bonding points and / or linear or wavy embossings can be arranged in the inner area of the wound dressing. Likewise, punching, ie material interruptions, are possible, preferably those whose edges are compacted.
