Thermally-driven textured fabric based on super-spiral composite fibers and preparation method of thermally-driven textured fabric

Abstract

The invention discloses a thermally driven textured fabric based on superhelical composite fibers and a preparation method thereof. The preparation method comprises the following steps: providing conductive fibers; forming an organic polymer coating layer on the circumferential surface of the conductive fiber to obtain a composite fiber; twisting the composite fibers to obtain super-spiral composite fibers; and weaving the super-spiral composite fibers to obtain the thermally-driven textured fabric. The fabric can generate size shrinkage under a thermal driving condition, so that the fabric structure becomes more compact, and the air permeability, the moisture penetrability, the light transmittance and the perspectivity of the fabric are reduced; after the thermal driving is removed, the fabric returns to the original size, the fabric structure returns to the original loose state, the size is enlarged, and the air permeability, the moisture penetrability, the light transmittance and the perspectivity are improved. The thermally-driven textured fabric based on the super-spiral composite fiber prepared by the invention can actively deform under a thermally-driven condition, and the permeability of the fabric can be adjusted. 本发明公开一种基于超螺旋状复合纤维的热驱动变形织物及其制备方法，所述制备方法包括步骤：提供导电纤维；在导电纤维圆周表面形成有机聚合物包覆层，得到复合纤维；对复合纤维进行加捻，得到超螺旋状复合纤维；将超螺旋状复合纤维进行编织，得到热驱动变形织物。该织物在热驱动条件下，可以产生尺寸收缩，从而使得织物结构变得更加紧密，织物透气性降低、透湿性降低、透光性降低、透视性降低；去除热驱动之后，织物回到原来的尺寸，织物结构回到原来较为疏松的状态，尺寸变大，透气性、透湿性、透光性、透视性回升。本发明制备得到的基于超螺旋状复合纤维的热驱动变形织物在热驱动条件下，可以主动产生形变，可实现对织物通透性的调节。
