    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.
