Kind Code:
B2
Abstract:
A method of activating down and fiber materials where there are disposed a plurality of nozzles for ionized air and nozzles for normal air alternately at proper intervals in the passage of the materials to be treated. The materials are subjected to ionization by ionized air ejected from the nozzles for ionized air produced by an ozonizer connected to the ionized air nozzles. Then the materials are subjected to normalization by normal air ejected from the normal air nozzles. This process is repeated several times while the materials are passing through the passage. The repeated processes of such alternate ionization and normalization allow the materials to be gradually and intensively ionized, resulting in producing finally activated materials which are characteristic of restored bulkiness and elasticity. An enclosure can also be adopted instead of the passage. In the enclosure the stationary materials are subjected to ionization by ionized air injected and after evacuation of the ionized air from the enclosure normal air is injected which will be evacuated afterward. One of the uses of this method is activation of down to be filled in quilts. But this method is also utilized for activation of other materials such as cotton, silk, chemical fibers, wool, paper, wood etc.
