The material processed comprises 20 per cent thermoplastic fibres, 74 per cent cellulose fibres, and 6 per cent water, and with a gram wt. of 300 g/m2. The air used to heat the material is heated to a temp. of 180 deg. C., and the heat energy required to heat a square metre of material from room temp. to 100 deg. C. is approximately 30 kW. The energy to evaporate the water is approximately 40 kW, ...

A method and an apparatus for controlling bed mites. Dry air is blown through the lying surfaces of a bed so as to dry the surfaces to an extent at which mite survival conditions no longer exist. The apparatus includes means (1-4, G1, G2) for ensuring that the bed lying surface will be dried preferably while the bed is not used as a bed.
