本发明涉及用于橡胶加固的钢帘线。钢帘线包括芯股和绞捻在芯股周围的至少三个外股,芯股包括至少一根第一芯单丝和绞捻在第一芯单丝周围的多根第一外单丝,每个外股包括多根第二钢单丝,多根第一外单丝中的至少一根第一外单丝在被绞捻到芯股中之前被预成型,并且第二钢单丝中的至少一根第二钢单丝在被绞捻以形成每个外股之前是直的。钢帘线在芯单丝迁移方面具有改善的性能。

    The invention provides a steel cord for rubber reinforcement. The steel cord comprises a core strand and at least three outer strands twisted around the core strand, the core strand comprises at least one first core filament and multiple first outer filaments twisted around the first core filament, each outer strand comprises a number of second filaments, at least one of multiple first outer filaments is preformed prior to being twisted into the core strand, and at least one of second steel filaments is straight prior to being twisted to form each outer strand. The steel cord has improved performance on core filament migration.
