一种用于中高支纯棉织物经纱无PVA上浆的纺织浆料
摘要：
本发明公开了一种用于中高支纯棉织物经纱无PVA上浆的纺织浆料，属于纺织领域。本发明的浆料组成按重量分数计：淀粉30-50wt％，助剂50-70wt％，所述助剂包括30-60wt％的阿拉伯胶、20-40wt％的果胶、10-20wt％聚丙烯酸-丙烯酰胺和4-10wt％的植物性油脂。该浆料对棉、粘胶等纤维素纤维纱线粘附力强，纱柔韧光滑，再生毛羽少，落浆落物少，退浆性能好，在30支-60支中高支纯棉织物经纱上浆中可完全取代PVA上浆，浆纱柔韧光滑，再生毛羽少，落浆落物少，可织性好，布机效率高，可达92％以上。
摘要（英）：

The invention discloses a textile size for PVA-free sizing of medium-and-high-count pure cotton fabric warps, and belongs to the field of textiles. The size comprises 30-50 wt% of starch and 50-70 wt%of assistants, and the assistants comprise 30-60 wt% of Arabic gum, 20-40 wt% of pectin, 10-20 wt% of polyacrylic acid-acrylamide and 4-10 wt% of botanical oil. The size has strong adhesion to cottonfiber, viscose glue and other cellulose fiber yarns, makes yarns be soft and smooth and have few reborn fluffs, less size falling and good desizing performance, can completely replace PVA sizing in sizing of 30 to 60 medium-and-high-count pure cotton fabric warps, and obtained sized yarns are soft and smooth, and have few reborn fluffs, less size falling, good weavability and a high blooming efficiency reaching 92% or above.
