Water-repellent flocculus and preparation method thereof

The invention belongs to the technical field of warm flocculi, and particularly relates to a water-repellent flocculus and a preparation method thereof. The preparation method comprises the followingsteps that (1), a polyester fiber warm flocculus is conveyed into a super-hydrophobic nanometer new material for dipping; (2), the dipped polyester fiber warm flocculus is fed into a roller press forrolling; and (3), the rolled polyester fiber warm flocculus is dried and shaped to obtain the water-repellent flocculus. The water-repellent flocculus has the effects of keeping warm, ventilation andbulking of common polyester fiber warm flocculi, further has functions of superhydrophobicity and self cleaning, a contact angle of the surface and water is greater than 150 degrees, a rolling angle is smaller than 10 degrees, the water-repellent effect is quite good, and the good water repellency can further be maintained after multiple washing. 本发明属于保暖絮片制备的技术领域，具体地说，涉及一种拒水絮片及其制备方法。所述的制备方法包括如下步骤：1)将聚酯纤维保暖絮片输送入超疏水纳米新材料中浸渍；2
