    摘要: A dryer fabric has a weft of cross machine direction yarns (6) and a first warp of first machine direction yarns (5) and a second warp of second machine direction yarns (9). The yarns of the first warp are arranged above the yarns of the second warp on a first surface (FS) side. The first warp has primary yarns (51) of PPS or PK yarns whose breaking load remains substantially stable within 15 days in conditions where RH=100%, T=125° C. and p=2.3 bar; and secondary yarns (52) of PET with breaking loads which substantially decrease under the same conditions. At least every second yarn of the first warp is a secondary yarn (52). The secondary yarns (52) may be two out of three or three out of four of the first machine direction yarns (5). PET reduces cost and adds elasticity to the dryer fabric.

    摘要: A slide fastener tape is provided. The slide fastener tape extends in a longitudinal direction. The slide fastener includes a weave structure formed with warp threads arranged in the longitudinal direction, and weft threads arranged along a transversal direction perpendicular to the longitudinal direction. The slide fastener tape includes a cord arranged along one side edge portion of the fastener tape. The weft threads are made from filament yarns and the warp threads comprise a plurality of threads made from spun yarn.
