Abstract

1,255,185. Coated sheet material. DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT. 19 Dec., 1968 [19 Dec., 1967]; No. 60350/68. Heading B2E. [Also in Divisions H3 and H5] In a process for the production of artificial leather, which includes the H.F. gelation of polyvinylchloride (P.V.C.) coated on a fabric, the dielectric heating electrode 1 is coated with a polytetrafluoroethylene. layer 2 to prevent high voltage breakdowns and scorching in the gelled material and to reduce the loss of heat therefrom to the electrode 1, which comprises a metal roller. The co-operating electrode 10 is arc-shaped. Current is fed to the roller electrode 1 through a carbon brush 11 sliding on a brass ring 12 on the roller. Alternatively, the electrode 10 is in two parts fed on the pushpull principle. Polyvinychloride (P.V.C.) to be gelled is applied as a paste from a vessel 5 to the roller 1 in front of a cooled coating knife 4. Behind the knife 4 is a guide roller 7 for the fabric to be coated, which is delivered from a roller 8. The pressure of roller 7 is varied through a weight 9. Any heat given off to roller 1 during cooling of the gelled material is used to preheat the new paste, the cooled coated fabric being taken off via rollers 13, 14. Tempering brine fills roller 1 and is kept at about 90‹C. Gelation of the P.V.C. between electrodes 1, 10 takes place at about 180‹C. The artificial leather may be given a smooth, embossed or perforated coating.
