提高交联棉织物染色性能的乙二醇类添加剂

从事研究,以便向工业界提供一种可染性的具有耐久定形整理性质的棉织物的生产方法,这就是说,其目的是要得到一种经过化学处理的耐久定形性质的织物,在整理后,可再被染色。在通常的耐久定形整理液中加入适当添加剂就能产生可染性的交联织物,这些能起到提高染色性能的添加剂中有氯化胆碱和三乙醇胺。可与交联剂反应。

交联棉织物染色性能的研究

通常，经Ｎ－羟甲基试剂交联的棉织物是拒染的。用８％Ｎ－羟甲基交联剂ＨＭＭ和１０％胆碱季铵盐制备的阳离子化棉织物，由于季铵盐基团的存在，对活性、酸性、直接等阴离子染料有较大的亲和力，大大地提高了交联免烫棉织物的染色性能。

潮交联整理棉织物性能与衬衫门襟缝线平整度关系

为提高潮交联整理棉织物制作衬衫时的缝线平整度,通过大量试验分析潮交联整理棉织物性能与门襟缝线平整度之间的关系,明显看出潮交联整理棉织物外观平整度、缩水、纬向弹性与门襟缝线平整度弱相关,经向弹性与门襟缝线平整度之间存在很强的正相关性,因此可通过改善潮交联整理棉织物的经向弹性,提高门襟缝线平整度。

Study on Different Modification Methods of Collagen for Tissue Engineering

Because of the excellent biocompatibility and its specific amino sequences,collagen is an ideal biomedical material for tissue engineering applications. But collagen is usually lack of mechanical strength to form a rigid 3-D matrix and lack of ability to resist collagenase. In order to be a tissue engineering scaffold,collagen must strengthen its structures by modifying with chemical crosslinkers. Chemical crosslinkers used for modifying collagen fibers include glutaraldehyde(GA),epoxy compounds(PC) and carbodiimides (EDC). The aim of this study is to choose the best chemical crosslinker from the three reagents. In terms of the resistance to collagenase degradation,chemical cross-linking with PC provided the best protection; in terms of the mechanical characterization,chemical cross-linking with GA provided the best;and in terms of the biocompatibility,chemical cross-linking with EDC provided the best.There is not a reagent which has all merits for collagen crosslinking,so we should select the crosslinking reagent as the demands of use ask.
