精练  用化学和物理方法去除棉、毛、麻、蚕丝织物中天然杂质、沾污物以及残存浆料的工艺过程。化学纤维织物的精练主要是去除纺织过程中的浆料和油污物。蚕丝织物的精练称为脱胶。棉、麻纺织物的精练俗称煮练。羊毛纺织物通过洗毛、洗呢去除杂质。    棉纺织物精练  主要是去除果胶质、含氮物质、油脂、棉蜡、棉籽壳等纤维素共生物,使纤维具有良好的吸水性和取得一定白度,以改善纺织物的染整性能。对纱线或织物均可进行精练。精练用剂早期使用的是含有碳酸钾(钠)的草木灰,以后改用石灰、碳酸钠(纯碱),现在常用的是氢氧化钠(烧碱),另加洗涤剂、硅酸钠(水玻璃)、亚硫酸氢钠和软水剂等助剂。棉纤维在较长时间的热碱溶液作用下,纤维上的油脂和游离脂肪酸会皂化成可溶性脂肪酸盐,将蜡质乳化,用水洗除。氢氧化钠能使含氮物质和果胶分别水解为可溶性的氨基酸盐和半乳糖醛酸等化合物,也可使多糖类物质水解,还能使棉籽壳溶胀体解。经过精练后棉纤维的失重一般在5~7%。棉纺织物精练的氢氧化钠用量,通常相当于织物重量的2.5~4%。精练方法有高压煮布锅精练、连续汽蒸常压精练和高温高压平幅连续汽蒸精练等(图1 、图2、图3)。       麻纺织物精练  亚麻的天然杂质在沤麻、脱胶过程中虽已大部分去除,但仍保留着一定量的非纤维素杂质,以避免?宋缮⒑褪е毓蟆Q锹橄宋弦资螅饭ひ展探匣汉汀>芳量捎锰妓崮疲锏拇硎奔湟话阍?6小时以上。苎麻织物精练与棉相似。    粘胶纤维织物精练  粘胶纤维织物不含天然杂质,精练目的是去除纺织过程中的浆料、润滑剂、着色剂以及尘土等外加杂质,可用碳酸钠或磷酸三钠再加洗涤剂,在80~90℃下进行处理。    合成纤维织物精练  合成纤维不含天然杂质,精练工艺条件缓和。锦纶织物可用碱剂和洗涤剂处理,洗涤剂应采用非离子表面活性剂。已定形织物,处理温度可在95~100℃;未定形织物宜在70~80℃,以免织物变形。腈纶织物遇热碱会泛黄,通常用非离子型洗涤剂处理。涤纶织物可用弱碱性溶液处理,温度不宜过高,时间也不宜过长。    蛋白质纤维纺织物精练  蚕丝纺织物是在碱性溶液中松式挂练,去除丝胶和杂质,取得一定的自然白度(见脱胶)。羊毛纺织物的精练,通过洗毛、洗呢工艺进行。
