色织纬纱上浆的工艺方法
摘要：
本发明提供一种色织纬纱上浆的工艺方法，其特征在于工序依次为：正常的筒纱染色→液体上浆→烘干，其中筒纱染色的柔软过程为加入平滑剂循环上染5-10分钟，液体上浆工序为加入液体浆料循环上染5-10分钟；液体浆料采用含固率为25％的丙烯酸酯液体浆料或浓度为100g/L的PVA液体浆料，当液体浆料采用丙稀酸类浆料时，液体浆料与色织纬纱的质量之比为20～50:1000；当液体浆料采用PVA液体浆料时，液体浆料与色织纬纱的质量之比为10～20:1000。经过本发明处理的纱线，强力提高10％左右，毛羽减少30％左右，大大提高了织造效率和织造后的色纺布的布面效果。
摘要（英）：

The invention provides a technological method for sizing dyed weft yarns. The technological method is characterized by sequentially comprising working procedures of normally dyeing yarns; sizing the yarns by the aid of liquid; drying the yarns. A softening procedure for dyeing the yarns includes circularly dyeing the yarns by the aid of smoothing agents for 5-10 minutes, and the working procedure for sizing the yarns by the aid of the liquid includes circularly dyeing the yarns by the aid of liquid sizing agents for 5-10 minutes; the liquid sizing agents are acrylic ester liquid sizing agents with solid contents of 25% or PVA (polyvinyl alcohol) liquid sizing agents with the concentration of 100 g/L, and a mass ratio of the liquid sizing agents to the dyed weft yarns is 20-50:1000 when the liquid sizing agents are acrylic acid sizing agents; a mass ratio of the liquid sizing agents to the dyed weft yarns is 10-20:1000 when the liquid sizing agents are the PVA sizing agents. The technological method has the advantages that the strength of the yarns treated by the aid of the technological method can be improved by approximately 10%, the hairiness of the yarns can be reduced by approximately 30%, and the weaving efficiency and fabric surface effects of woven color-spun fabrics can be greatly improved.
