Description
技术领域
本发明涉及服装面料加工领域,特别是涉及一种薄型羊毛针织面料的生产工艺。
背景技术
羊毛为天然环保纤维,具有弹性好、染色牢度佳等特点,以其为原料制成的面料是高档服装的首选面料。但是目前市场上的羊毛面料绝大部分是用梭织生产的,如制成各种大衣、西装、西裤的呢绒面料,在针织上多是在横机上生产的羊毛衫及围巾帽子等,坯布染色过程中需承受更大的张力、更高的温度、更长的湿态时间,所以很难批量生产。
发明内容
为克服现有技术上的不足,本发明目的是提供一种薄型羊毛针织面料的生产工艺。
为实现本发明的目的,本发明的技术方案如下:
一种薄型羊毛针织面料的生产工艺,包括以下步骤:
a.织造:选用16.7tex单纱防缩羊毛作为原材料,将单纱防缩羊毛在圆纬机上进行编制,得到质量良好的毛胚织物;
b.配缸:将毛胚织物放入染缸中;
c.预处理:在染缸中加入预处理剂进行处理;
d.染色:在染缸中加入染色剂进行染色,染色剂的组成成分为:染料8~10%,螯合剂YH-56 0.3%,冰醋0.2%~0.6%,阿白格B 2%,元明粉5%,浴中宝C 2%,其余成分为水;
e.防蛀整理:在染缸中加入柔软防蛀剂JFF;
f.柔软定型:在染缸中加入定型液进行定型,定型液的组成成分为:柔软剂321430%,酸性调节剂ACR 1.2%,其余成分为水。
上述一种薄型羊毛针织面料的生产工艺,其中,所述预处理剂的组成成分为去油剂2%,浴中宝C 2%,纯碱1.2%,其余成分为水。
上述一种薄型羊毛针织面料的生产工艺,其中,所述染缸内温度为50~60℃。本发明的有益效果:在染色过程中加入浴中宝C,可以防止织物在染色时产生擦伤,减少毛羽产生,提高了织物的抗起毛起球性能,染色完成后对织物进行防蛀整理,可有效预防蛀虫对羊毛织物的损伤,对织物进行呢毯定形整理,织物手感柔软、布面平整,尺寸稳定性好,且能够批量生产。
具体实施方式
为使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解,下面结合具体实施方式,进一步阐述本发明。
实施例1:一种薄型羊毛针织面料的生产工艺,包括以下步骤:
a.织造:选用16.7tex单纱防缩羊毛作为原材料,将单纱防缩羊毛在圆纬机上进行编制,得到质量良好的毛胚织物;
b.配缸:将毛胚织物放入染缸中;
c.预处理:在染缸中加入预处理剂进行处理;
d.染色:在染缸中加入染色剂进行染色,染色剂的组成成分为:染料8~10%,螯合剂YH-56 0.3%,冰醋0.2%~0.6%,阿白格B 2%,元明粉5%,浴中宝C 2%,其余成分为水;
e.防蛀整理:在染缸中加入柔软防蛀剂JFF;
f.柔软定型:在染缸中加入定型液进行定型,定型液的组成成分为:柔软剂321430%,酸性调节剂ACR 1.2%,其余成分为水。
上述一种薄型羊毛针织面料的生产工艺,其中,所述预处理剂的组成成分为去油剂2%,浴中宝C 2%,纯碱1.2%,其余成分为水。
上述一种薄型羊毛针织面料的生产工艺,其中,所述染缸内温度为50~60℃。
本发明在染色过程中加入浴中宝C,可以防止织物在染色时产生擦伤,减少毛羽产生,提高了织物的抗起毛起球性能,染色完成后对织物进行防蛀整理,可有效预防蛀虫对羊毛织物的损伤,对织物进行呢毯定形整理,织物手感柔软、布面平整,尺寸稳定性好,且能够批量生产。
以上所述仅为本发明的实施例,并非因此限制本发明的专利范围,凡是利用本发明说明书所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。
