抓毛绒（Polar fleece，简称fleece），又称双面刷毛布或摇粒绒，是一种柔软、表面带有绒毛的合成纤维布料，由聚对苯二甲酸乙二酯（英文：Polyethylene terephthalate，缩写PET）所制成。第一种抓毛绒于1979年由Malden Mills发明。抓毛绒有部份羊毛的优点，但重量比羊毛轻得多。

抓毛绒常被用作制成风褛、帽、毛衣、运动裤、帽衫、运动服装等。其生产原料有中有部份是使用回收塑胶樽，质地非常柔软、轻，而且容易清洗。

Aaron Feuerstein故意放弃对抓毛绒的专利权，使得此布料得以由多间厂家生产，增加了产量，从而使价值下降并被广泛使用。

Polar fleece is a soft napped insulating fabric made from a type of polyester called polyethylene terephthalate (PET) or other synthetic fibers. Other names for this fabric are "Polar Wool," "Vega Wool," or "Velo Wools." Despite names suggesting the product is made of natural material, polar fleece is 100% polyethylene terephthalate.
