Definitions
- the present invention relates to a method for modifying the odor properties textile materials and the textile materials obtainable by this process.
- Textiles tend due to their fiber structure and the associated large specific Surface for absorbing odor-causing substances.
- body sweat is adsorbed by the textile fibers and there under Training unpleasant smelling substances degraded. These are often so tight in They are also bound by washing or cleaning bad or impossible to remove.
- they are in low Amounts that are above the odor threshold, released to the environment, so that even washed or cleaned textiles have an unpleasant smell of sweat exhibit.
- Cyclodextrins are cyclic oligosaccharides, the be formed by enzymatic degradation of starch.
- the most common cyclodextrins are ⁇ -, ⁇ - and ⁇ -cyclodextrins consisting of six, seven and eight ⁇ -1,4-linked, respectively Glucose units exist.
