    • The present invention is a method for coloring knit, woven, or non-woven protective textiles made from yarns containing at least 20% synthetic high tenacity fibers, such as para-aramid or liquid crystal polyester (“LCP”), and for package-dyeing and skein-dyeing of such yarns. In embodiments, the textile is scoured to remove any impurities. A base coating of an adhesion promoting primer is then applied, which is typically a polymer or elastomer. The textile is typically immersed at zero tension in the primer liquor for an extended period. Afterward, the primer is dried and then cured at an elevated temperature to cross-link the primer and provide wash-fastness. A dye or printing ink of substantially any desired color and intensity is then applied. The protective yarns can include staple fibers and/or continuous filament fibers. The invention is further applicable to drum coating, jig processing, dye beck and other dying and coating processes.
    • 本发明是对由含有至少20%的合成高强度纤维(例如对位芳族聚酰胺或液晶聚酯(“LCP”))的纱线制成的编织,编织或非织造保护性纺织品着色的方法, 这种纱线的染色和绞纱染色。 在实施方案中,洗涤织物以除去任何杂质。 然后施加粘合促进底漆的基底涂层,其通常是聚合物或弹性体。 纺织品通常在引导液中的零张力下长时间浸没。 之后,将底漆干燥,然后在高温下固化以交联底漆并提供耐洗涤性。 然后施加基本上任何期望的颜色和强度的染料或印刷油墨。 保护纱线可以包括短纤维和/或连续长丝纤维。 本发明还可应用于滚筒涂布,夹具加工,染料染色和其他染色和涂布工艺。
