摘　　要：针对单面纬平针织织物平幅轧蒸染色中容易卷边的问题,采用浆边的方法来控制卷边,并对防卷边涂层胶所用浆料及施加方式进行选择和优化。通过对比浆边织物平幅轧蒸染色各工况下的卷边率及其耐洗性,筛选出聚丙烯酸酯-聚氨酯浆料用于针织物平幅轧蒸染色中的防卷边整理,并通过工艺优化,获得了适合中、厚型单面纬平针织物的防卷边施胶方式:于单面纬平针织物的反面,沿织物纹路方向进行锯齿状刮涂,浆膜厚度达到0.2 mm,浆边宽度不低于2 cm。结果表明,这种防卷边施胶方式在平幅轧蒸染色的各工况下都可有效地控制织物的卷边,且不会影响后续的染色效果。The edges of single-weft knitted fabric was treated with paste to prevent the edges from curling during the open width pad-steam dyeing process. The sizing agents and their coating applied ways were optimized by comparing the curling rates and washing durability during open-width wet processing. As a result, the polyacrylate-polyurethane was used as a sizing agent. The suitable processes for medium weight and thick knitted fabric are as follows: the serrated coating is applied along the grain direction on the reverse side of fabrics, and the thickness of the coating reaches 0. 2 mm. The width of the coating is no less than 2 cm. The results show that the method can effectively control the curling of the knitted fabric in the open width pad-steam dyeing process and has no effect on the dyeing performance.
