Unverified压缩袋压缩率越高越省空间，但衣物长期高度压缩会破坏纤维弹性（尤其羽绒、羊毛），羽绒制品建议压缩不超过原体积的50%且每季松开一次91% similarUnverified压缩袋越省空间越易导致衣物压皱、纤维回弹变差，对易皱的西装、精纺羊毛衫应选'弱压缩'或改用防尘袋，纯棉/化纤厚衣物才适合深度压缩89% similarUnverified压缩比越高（越薄）单位空间越省，但物品受压越紧、纤维恢复越差；棉被追求省空间可压缩，衣物长期存放建议留20-30%余量保护面料87% similarUnverified压缩比越高（真空度越大）越省空间，但衣物纤维受挤压越严重，棉麻针织类易产生难以恢复的深折痕，建议压缩到七八成即可而非完全抽真空87% similarUnverified压缩比越高衣物纤维压缩越狠，羽绒/羊毛等靠蓬松度保暖的衣物长期高压缩会永久性损伤纤维，这类衣物只做50%左右轻度压缩或改用真空防潮盒86% similar
