| 摘要 |
A gel profile article comprising a multi-filament yarn carrier carrying an elongate body of gel which encloses more than 50 %, preferably more than 75 %, more preferably substantially all, of the perimeter of the carrier as viewed in transverse cross section, wherein the carrier is at least partly composed of synthetic polymeric material, preferably polyester filaments (e.g. polyethylene terephthalate) or spun yarns of a co-mingled blend of polyacrylonitrile staple fibres and polyamide staple fibres ("baby wool"), the proportion of polyamide preferably being at least 30 %, more preferably 40-60 %, by weight of the said spun yarn(s). The gel is preferably melt-coated, especially pressure-extruded, around the carrier at a gel temperature less than the softening temperature of at least a component of the carrier, and the selected class of carrier materials enhances the processability, cohesion, and appearance of the resulting profile. |
