Description
技术领域
本发明属于纱线生产技术领域，具体涉及一种膨体混纺纱的制备方法。
背景技术
现有技术中的蓬松型纱线通常称为花式线，是利用超喂原理得到的具有各种外观特征的纱线，如圈圈线、竹节线、螺旋线、结子线等。此类纱线织成的织物手感蓬松、柔软、保暖性好，且外观风格别致，立体感强，既可用于轻薄的夏季织物，又可用于厚重的冬季织物，既可做衣着面料，又可做装饰材料，上述花式线的蓬松状态成非均一状态，即蓬松状态呈截断状出现，或者纱线外缘为扁平状。
改进的技术采用涤纶腈纶为收缩纤维，通过混纺加入普通纤维，利用纤维经过处理后收缩率差异，得到膨胀状态的混纺纱。但是，涤纶和腈纶均为合成纤维，亲肤性和服用性能相对与天然纤维较差；其次，涤纶腈纶纤维的受热收缩范围最大可达45%左右，加热处理收缩率不易控制；另外，上述两种材料在后期受热例如沸水条件下还会发生进一步收缩，影响织物尺寸稳定性。
发明内容
本发明的目的之一在于克服现有技术中存在的缺陷，提供一种膨体混纺纱的制备方法，在混纺纤维中添加水溶性维纶和Optim Max纤维，利用水溶性维纶可退维溶解和Optim Max纤维水热处理后收缩的特性，所得纱线呈蓬松状态，适用于轻薄贴身面料的织造。
为实现上述目的，本发明的技术方案为：一种膨体混纺纱的制备方法，其特征在于，所述膨体混纺纱的原料纤维包括维纶纤维、Optim Max纤维和普通纤维，维纶纤维的混纺比为10~30%，Optim Max纤维的混纺比为8~15%；制备方法包括混纺合股成纱、退维、混纺纱含水静置、清洗烘干步骤，
其中，混纺纱含水静置的工艺过程为：将退维处理的包芯纱带液静置处理，静置温度为35~45℃，静置环境相对湿度为60~70%，时长为36~72h。
普通纤维为丝光羊毛纤维、棉纤维、粘胶纤维和竹纤维中的至少一种。
膨体混纺纱有高支单纱和低支单纱合股而成，高支单纱捻系数为300~450，低支单纱的捻系数为200~300，合股的捻系数为低支单纱捻系数的0.67~0.7倍，高支单纱由OptimMax纤维和普通纤维混纺而成，低支单纱由维纶纤维和普通纤维混纺而成。
膨体混纺纱的原料纤维组成为维纶纤维20~30%、Optim Max纤维10~15%、丝光羊毛纤维30~45%和棉纤维15~25%，Optim Max纤维与棉纤维混纺，丝光羊毛纤维与维纶纤维混纺。
退维处理液为pH值为5-6的乙酸溶液，退维温度为93~95℃，退维处理时间为40~60min。
本发明的优点和有益效果在于：
本发明蓬松型羊毛纱线的制备方法步骤简单，通过在混纺纤维中引入水溶性维纶和Optim Max纤维，退维后水溶性维纶溶解，在Optim Max纤维和普通纤维之间留下形变间隙，同时利用Optim Max纤维水热处理后收缩的特性，Optim Max纤维收缩缠绕在普通纤维外或者夹杂在普通纤维之间，使得与Optim Max纤维相邻的其他纤维呈蓬松状态；
处理后的Optim Max纤维在制造或者后期穿着过程中收缩量低，面料的尺寸稳定。
具体实施方式
下面结合实施例，对本发明的具体实施方式作进一步描述。以下实施例仅用于更加清楚地说明本发明的技术方案，而不能以此来限制本发明的保护范围。
