Unverified免烫衬衫分'纯棉免烫'和'混纺免烫'两类：纯棉免烫通过液氨或树脂整理实现，透气好但抗皱等级通常DP3-3.5级；聚酯混纺（棉≤60%）抗皱可达DP4级以上但透气差、易闷汗90% similarUnverified免烫衬衫的免烫工艺分为树脂免烫和后整理免烫，树脂免烫（含DP等级标注，DP≥3.5为高档免烫）耐久性强但可能残留甲醛，敏感肌应选购后水洗3次以上87% similarUnverified追求真正免烫零打理选涤棉混纺（涤纶≥35%）或含氨纶弹力款，DP等级达4.0以上；重视舒适透气则选纯棉DP免烫（DP3.2-3.5），但脱水后需抖平晾挂，仍会有轻微褶皱85% similarUnverified免烫抗皱多依赖树脂整理或高支纯棉+特殊工艺，免烫等级达3.5级以上（AATCC标准）洗后基本免熨；但树脂免烫会牺牲透气性并可能残留甲醛，敏感肌选『物理免烫』或天丝混纺84% similarUnverified免烫衬衫按防皱工艺分三类：纯棉液氨免烫（DP等级3.2-3.5）手感最好但透气一般，棉+聚酯混纺（涤棉65/35）抗皱最强适合出差频繁者，纯棉+树脂免烫（甲醛残留风险）建议避开。DP等级≥3.5才算真正免烫、洗后可直接穿83% similar
