This research aimed to weave the warp indigo-dyed cotton yarn with un-dyed or dyed silk yarn and analyze the impact of different weft yarn structures on the properties of denim fabrics. The dyed silk yarn was performed by a selection of different anionic indigo and non-indigo blue dyestuffs. The dyeing shades of the anionic Indigo Carmine dye on silk exhibited high build-up at the acidic pH range 2-2.5 with poor washing fastness and even so, the cationic aftertreatment of the dyed silk samples showed un-matched color with indigo-dyed cotton yarns. The dyeing properties of two commercial non-indigo reactive and acid dyes on silk add other advantages. To ascertain the dyeing shades evaluation of the non-indigo dyes on silk, two sets of blended denim fabrics were investigated. The first set included a weft-wise silk yarn dyed with reactive dye RB 5, and the second set included silk yarns dyed with acid dye AB 193. Weaving of the blended fabrics was carried out in Twill 3/1, 3/2 Z,and Satin 5 patterns and exhibited significant color effects of the dyed silk yarns to those of the un-dyed control samples. The dyeing shades of the non-indigo RB 5 and AB 193 dyed weft-wise silk yarns were found to be matched in color performance with the conventionally indigo- dyed cotton yarns. Ultraviolet resistance of the blend denim fabrics was evaluated, showing significant improvement in UPF of the weft-wise dyed silk. The study claimed that the dyed silk yarns a good candidate for newly developed blend denim fabrics.
本研究旨在将经靛蓝染色的棉经线与未染色或已染色的丝线交织，并分析不同纬纱结构对牛仔布性能的影响。染色丝线采用了多种不同的阴离子靛蓝和非靛蓝蓝色染料。阴离子靛蓝胭脂红染料在丝线上的染色深度在酸性pH值范围2 - 2.5时表现出较高的上染率，但水洗牢度较差，即便如此，对染色丝线样品进行阳离子后处理后，其颜色与靛蓝染色的棉纱不匹配。两种市售的非靛蓝活性染料和酸性染料在丝线上的染色性能具有其他优势。为确定非靛蓝染料在丝线上的染色深度评价，对两组混纺牛仔布进行了研究。第一组包括用活性染料RB 5染色的纬向丝线，第二组包括用酸性染料AB 193染色的丝线。混纺织物以斜纹3/1、3/2 Z和缎纹5组织进行织造，与未染色的对照样品相比，染色丝线呈现出显著的颜色效果。发现非靛蓝RB 5和AB 193染色的纬向丝线的染色深度在颜色性能上与传统靛蓝染色的棉纱相匹配。对混纺牛仔布的抗紫外线性能进行了评估，结果表明纬向染色丝线的UPF有显著提高。该研究称，染色丝线是新开发的混纺牛仔布的良好候选材料。
