一种新型的无甲醛免烫整理技术——离子交联法

Ionic crosslinking method: a novel formaldehyde-free durable-press finishing technique

用离子交联赋予纤维素纤维织物耐久压烫性能,此法不含游离甲醛.纤维素纤维织物可与阴离子物质如氯乙酸(或其他活性阴离子物质)和阳离子物质如3-氯-2-羟丙基三甲基氯化铵(或阳离子化壳聚糖等)反应,在纤维之间形成交联,整理后织物的折皱回复角得到明显提高,而强度基本不变.

Ionic crosslinking was used to endow the cellulosic fabrics with durable press performance. This method used no formaldehyde. The fabrics of cellulosic fibers may react with anionic substances, e.g., chloroacetic acid （or other active anionic ones）, and cationic ones, e.g., 3-chloro-2-hydroxypropyltrimethylammonium chloride （or cationized chitosan） to form crosslinking between the fibers. The finished fabrics showed obviously increa- sed wrinkle recovery angles, and the strength was substantially retained.
