标题: ［建议］国产也有好染料
一.可用于羊毛.丝绸.锦纶染色用的新一代S-系列金属络合染料品种.该系列染料填补了国内高档毛纺染料的空白.打破了毛纺行业高档染料一直由国外公司垄断的局面.为国内外追求高质量的毛纺企业提供了广泛的选择.该染料以其特有的高上色率.优异的匀染性.较高的染色重现形及及高的染色坚牢度可以与国外高档的同类染料相媲美.<br />二.特点:<br />&nbsp; &nbsp; 1.羊毛染色系统化,建议染厂采用该染料染色系统组合(S-系列染料;染色PH=4.5~5.5;匀染剂OV)<br />&nbsp; &nbsp; 2.注重羊毛保护,在羊毛等电点染色,保证羊毛损伤最低.<br />&nbsp; &nbsp; 3.关注环保,满足OEKO-STANDARD 100环保标准要求.<br />&nbsp; &nbsp; 4.重视染色产品全面的高染色坚牢度.<br />&nbsp; &nbsp; 5.保证染料的配伍性,提高染色重现性,减少匹差和缸差,提高染色质量.<br />&nbsp; &nbsp; 6.相同的染色工艺,操作方便简单.<br />三.适用范围<br />&nbsp; &nbsp; 1.常规羊毛的散毛.毛条及纱线的染色.<br />&nbsp; &nbsp; 2.用于防缩羊毛.丝光羊毛及羊绒的染色.<br />&nbsp; &nbsp; 3.可与阳离子染料同浴用于羊毛/晴论混纺染色;与直接染料同浴用于羊毛/纤维素纤维的染色;可与活性染料配套,采用两浴工艺对锦纶(尼龙)/棉染色.羊毛/纤维素纤维混纺的染色,可达到较高染色牢度.<br />四.染料品种<br />&nbsp; &nbsp; 黄S-GG.橙S-R.红S-GN. 红S-2B. 酱红S-BR.棕S-3R. 棕S-GR. 藏青S-R. 灰S-BG. 黑S-2B.<br />五.染色<br />&nbsp; &nbsp; 1.染料:采用S系列染料.<br />&nbsp; &nbsp; 2.PH值:<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; (1).不同的色泽,染料用量及染色织物的状态,均采用同一的染色PH值(PH=4.5~5.5)<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; (2).采用醋酸和醋酸钠组成的缓冲溶液系统,确保在羊毛等电点染色,保证羊毛纤维损伤最低.<br />&nbsp; &nbsp; 3.配套的匀染剂和渗透剂,它们都是两性的液体助剂,对羊毛及染料都有亲合力.<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; (1)匀染剂:提高染料相容性和配伍性,同时可以有效防止染料凝聚,确保染色重现性和匀染性;改善染料对毛尖和毛根的遮盖力.<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; (2).渗透剂:是具有润湿,渗透和消泡作用的多功能复合助剂.<br />六.染色方法<br />&nbsp; &nbsp; 1.染料溶解:先用冷水将染料打成均匀的浆状,然后加入沸水或用直接蒸汽沸煮至染料完全溶解,降温,最好经过过滤加入到染缸中.<br />&nbsp; &nbsp; 2.羊毛染色工艺<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; (1).散毛及毛条染色<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;前处理:加入0.5克/升渗透剂,于70度保温30分钟,排液2/3,然后加水到规定浴比.<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;染色处方:&nbsp; &nbsp;A&nbsp; &nbsp;渗透剂&nbsp;&nbsp;0.5克/升<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;匀染剂&nbsp;&nbsp;1.0%<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;元明分&nbsp;&nbsp;5~10%(浅色:10%,中色:5%,深色不加)<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;醋酸钠&nbsp;&nbsp;2克/升<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;醋酸&nbsp; &nbsp;&nbsp;&nbsp;X%<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;PH=4.5~5.0<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;B&nbsp; &nbsp; 染料&nbsp; &nbsp;X%<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; (2).纱线及匹布染色工艺<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; 羊毛织物前处理:加入0.5克/升渗透剂,以碳酸钠或氨水调PH=8.0,于70度保温30分钟,排水.清洗,以醋酸中和至PH=5.5~6.<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;染色处方:&nbsp;&nbsp;渗透剂&nbsp;&nbsp;0.8克/升<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;匀染剂&nbsp;&nbsp;1.0%<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;元明粉&nbsp;&nbsp;5~10%(浅色.中色:10%,深色5%)<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;醋酸钠&nbsp;&nbsp;2克/升<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;醋酸&nbsp; &nbsp;&nbsp;&nbsp;X% <br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;PH=4.5~5.5&nbsp;&nbsp;(染色深度高于2.5%时,调PH=4.5~5)<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; 染料&nbsp;&nbsp;X%<br />七.其它注意事项<br />&nbsp; &nbsp; 1.调色:该系列染料可以用于调色,但必须注意,在添加调色染料前,首先要将染浴冷却至70~75度,然后加入溶解好的调色染料<br />&nbsp; &nbsp; 2.修色:若发现染色过深或稍有染色不均匀现象时,可以用以下方法改浅15~20%,方法如下:<br />&nbsp; &nbsp;&nbsp;&nbsp;在新鲜染浴中加入:&nbsp; &nbsp;2~3%匀染剂<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;10~15%无水元明粉<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;以醋酸调节PH=6~6.5<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;在80度处理30~40分钟<br />&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;或在103度处理15分钟即可
