一种持续冷感调温纱及其制造方法
技术领域
本发明属于纺织技术领域，涉及一种持续冷感调温纱及其制造方法。
背景技术
相变材料(PCM)是指温度不变的情况下，改变物质状态，并能提供潜热的物质。目前，在冷感调温纱同类产品中，PCM在纱线当中的应用，仅有融入在纱线中的技术，没有芯鞘构造。而现有技术的冷感调温纱，仅有很少部分的PCM可以融入纱线中，例如5％以内的PCM可以融入纱线中，其主要存在如下两点缺陷：1、很难实现长丝构造；二、即便PCM可以融入纱线中，融入量也很少，仅有5％以内，效果体感无法满足要求。
发明内容
本发明提供一种持续冷感调温纱及其制造方法，能够克服现有技术所存在的上述缺陷，实现将更多的PCM注入纱线中，能够使得冷感更强，使得产品使用效果更好。
为实现上述目的，本发明采用如下所述的技术方案：
本发明的一种持续冷感调温纱，所述持续冷感调温纱的纤维包括外皮部分和内芯部分，所述外皮部分包裹在所述内芯部分外部，所述内芯部分为PCM原料制得，所述PCM的横截断面面积百分比占所述纤维横截断面面积的5～70％。
优选的，外皮部分为PE原料(聚乙烯)制得。
优选的，PCM原料为熔点范围是20-39℃的相变材料。
本发明的一种持续冷感调温纱的制造方法，包括以下步骤：
分别将所述PE原料组份和所述PCM原料组份送入加热熔融装置；
其中将所述PE原料组份送进加热螺杆，通过电加热均匀熔融，并在所述加热螺杆的作用下挤进计量泵；
将所述PCM原料组分通过带搅拌装置的加热容器熔透；
根据所需产品的纱支粗细程度，计算所述PE原料组份和所述PCM原料组分的挤出量，通过调整所述PE原料组份和所述PCM原料组分的所述计量泵的转速得到所述PE原料组份和所述PCM原料组分的准确份量；
所述PE原料组份和所述PCM原料组分在所述计量泵作用下进入组件，通过熔体流向分别进入喷丝板，在所述喷丝板中形成所述PE原料组份的所述外皮部分、所述PCM原料组分的所述内芯部分，所述外皮部分和所述内芯部分合二为一共同挤出所述喷丝板，再经过冷却、上油集束来进入卷绕部分；
在所述卷绕部分，将从所述喷丝板挤出的丝缠绕在第一热辊上加热，再将加热后的所述丝进入第二热辊定型；通过所述第二热辊与所述第一热辊的速度差对所述丝拉伸；将从所述第二热辊出来的所述丝进入网络装置增加抱合性，然后将所述丝缠绕在卷绕头上的纸管，形成成品丝饼。
优选地，将所述PE原料组份送进加热螺杆，通过电加热均匀熔融，并在所述加热螺杆的作用下，通过10MPa的压力挤进计量泵。
优选地，将所述成品丝饼检验分级，然后包装出厂。
本发明的有益效果是：
本发明的持续冷感调温纱及其制造方法，能够实现将更多相变材料pcm直接注入纤维芯部，从而实现了纺织产品更高的冷感值，大大提高了产品持续冷感性，更好地满足了用户冷感体验，填补了市场空白。
