Patent ID: 7051572

Claim:
A process for determining the odor-inhibiting properties of textile auxiliaries, where the following process steps a) to e) are carried out with a fabric to which the textile auxiliary to be investigated has been applied beforehand, and additionally with a fabric of the same provenance to which this textile auxiliary has not been applied: a) application of a gaseous or volatile substance (substance A) to a fabric, b) either b1) extraction of a sample of the resulting fabric with a solvent in which substance A is readily soluble or b2) heating a sample of the fabric obtained after carrying out step a) in a closed apparatus under conditions under which essentially complete desorption of substance A into the gas phase takes place, but no chemical decomposition of substance A, c) determination of the amount of substance A extracted when carrying out step b1), or determination of the amount of substance A present in the gas phase after carrying out step b2), d) storage of another sample of the fabric obtained after step a) at room temperature in a closed apparatus, e) determination of the amount of substance A present after step d) in the gas phase in the closed apparatus, where substance A is either itself odor-active or a component of an odor-active mixture of substances, where steps d) and e) can be carried out from the point of view of time before or after steps b) and c).
