Unverified真正抗皱免烫的多为涤纶/尼龙+氨纶混纺或T400弹力面料，纯棉/亚麻标注'免烫'多依赖化学定型整理，洗涤10次以上抗皱性会明显衰减87% similarUnverified免烫抗皱的关键看混纺配比，涤纶（聚酯纤维）占比60%以上抗皱最佳但透气差，全棉需看是否做过液氨免烫整理，标注'防皱'的纯棉实际水洗几次后效果会衰减87% similarUnverified免烫效果主要靠面料结构与树脂整理，聚酯纤维（涤纶）含量≥65%才能保证水洗后基本不用熨烫；含量低于50%的棉混纺免烫标称多为营销话术，实际下水后仍会皱86% similarUnverified可复用布选涤锦混纺（涤纶80%+锦纶20%）比例，锦纶提供吸水与耐用性，此配比可机洗100次以上不显著掉毛；纯涤纶布洗几次后易变硬86% similarUnverified抗皱免烫处理越强，面料越硬挺、透气性越差、贴身舒适度越低；纯棉免烫多用树脂整理，可能残留微量甲醛需买后过水86% similar
