A growing body of evidence suggests that osteoarthritis (OA) is not simply a disease related to aging or mechanical stress of joints but rather a"metabolic disorder"in which various interrelated lipid and metabolic mediators contribute to the initiation and progression of the disease process. One such metabolic risk factor could be high cholesterol

1　引　言　　纤维素纺织品含有一些杂质如脂肪、蜡、果胶和天然色素等。为了去除这些杂质 ,坯布必须进行预处理 ,以保证染色、印花和整理的质量。常规的预处理工艺将棉坯布分别通过以下三个步骤转变为完全漂白织物 :退浆去除浆料 ;煮练去除脂肪、蜡和果胶 ;漂白去除色素。考虑到以上三个步骤中总能量消耗很大 ,近年来着重开发了降低能耗的各种其他方法。这些步骤合并起来能减少处理的步骤 ,这已成为一种趋势。本文反映了这些领域的最新情况。2　丝光和煮练一步法　　Duckworth和 Wrennall在 1 977年报导了热丝光的优点和经济效果 ,在此丝光步骤中包含汽蒸室 ,可同时进行煮练。3　退浆、煮练和漂白一步法　　由于能耗持续不断上升 ,有的文献报道了有工业化价值的退浆、煮练和漂白一步法预处理工艺的发展情况。对这一方法的研究还指出 ,采用自身可乳化的溶剂助染系统 ,并加入过氧化氢 ,有可能将退浆、煮练和漂白这三个预处理步骤结合成一步预处理工艺。这项研究还发现经丙烯上浆的织物漂白比较容易 ,成本也较低。有些文献已报道 ,联合工艺在大多数情况下都使用过氧化氢 ,它能降低水和蒸气的消耗。用一步法处理后的织物具有良好的预处理张力强度、极好的白度和很高的润湿性。一步法工艺也可去除诸如外来颗

关键词：浴法中不包括丝光的原因主要是因为退浆、煮练和漂白三个过程都是在高温下进行的而在这样的条件下丝光反应不好因为氢氧化钠和纤维素的反应是高度放热的。有人已对退浆、煮练、漂白和丝光一浴法工艺的可能性作了研究。1997年发表的方法是将这四种处理结合起来在各种温度

1 引言水相加工耗能大,同时也产生了大量的废水。二三十年前,人们致力于用有机溶剂取代水作为溶剂的研究。大部分有机溶剂具有挥发性,有毒的溶剂蒸气破坏了生态稳定,所以这种方法同样也存在不足之处,因为它仅仅将水污染问题转变成了空气污染。我们知道工业上将二氧化碳用作萃取溶剂已有很多年的历史。在现已建立的咖啡和茶叶脱除咖啡因和可可脱除植物油的工艺中,有很多是用
