| titleOfInvention | Twisted polyester multifilaments and their use as part of a power transmission element |
| abstract | The twisted polyester multifilaments are used in a drive belt, which is placed under tension between two disks. After 48 hrs., the belt tension has dropped by not more than 35% from the start value, and does not drop further after this time The polyester multifilaments are not of high module filaments, twisted in a single- or multistage. The twisted material (1) has a thickness of 800-1700 dtex, with twisting stages of 0-250 twists/m, 0-10 twists/m and 50-250 twists/m. The filaments are coated with an adhesive bonding agent of resorcinol-formaldehyde-latex. In the belt structure, the twisted cords (1) are flanked by layers of mixed polymer and/or glass fibers. The belt tension does not drop below 25%. The hysteresis in the load extension diagram is <= 3.5% after 30 cycles. An Independent claim is included for a mfg. process, where the twisted and coated cord is drawn and heated simultaneously in at least three temp. and drawing zones. The temp. in the first zone is sufficiently high to evaporate the solvent from the adhesive coating, and form a film on the filaments. The second zone has a higher temp. to form an interlinking mesh structure through the reaction between the coating and the mols. at the filament surfaces. The third zone has a lower constant temp. in a range of -20 deg C to +140 deg C. Preferred Features: The first zone has a constant temp. of 60-160 deg C, the constant temp. in the second zone is 160-260 deg C and, in the third zone, there is a constant temp. of -20 deg C to +140 deg C. When using four stages, the filament tension between the first two zones is 100-800 N/tex, 400-1400 N/tex between the second and third zones, 400-1500 N/tex between the third and fourth zones and after the fourth zone. The first temp. zone is at 60-160 deg C and pref. 100-120 deg C, 160-260 deg C and pref. 190-230 deg C in the second zone, at -20 deg C to +140 deg C in the third zone and pref. 10-90 deg C with -20 deg C to +140 deg C in the fourth zone and pref. 10-90 deg C. |
