Description

一种锦棉一浴法染色方法
技术领域
本发明涉及纺织品染色领域,尤其涉及锦棉一浴法染色方法。
背景技术
锦棉是锦纶和棉的混合织物,锦纶含量50％以上,汇聚两种纤维的优点,既具有锦纶的耐疲劳性而表现出坚挺的身骨等特点,又保持了棉的透气性、吸湿性和穿着舒适性的优点,又深受消费者的青睐,成为一种国际流行的时尚面料,市场前景良好。但由于锦纶纤维与棉纤维物理结构和化学性能相差较大,其染整工艺较为复杂,染色难度大,技术要求高。一直以来,锦棉染色均采用先染棉再套染锦纶的活性/酸性、活性/中性等二浴法染色工艺,但该类染色工艺存在流程长、耗时多、耗能高、染料易沾色、织物易受损伤、弹性差、成本高、产能低等,大大降低了锦/棉织物的市场竞争力。因此,锦棉一浴法染色工艺一直是染整技术人员关注探讨的问题之一。
中国专利申请号201711307790.8的发明公开了一种锦棉梭织物活性酰胺染料一浴法染色方法,按以下步骤进行：坯布准备→冷堆前处理→平洗→染色配方设计→溢流染色→开幅→烘干→定型→成品检验,根据其实施例中的数据,使用活性酰胺枚红CRN-4B0.4％,活性酰胺大红CRN-4G 4.5％,元明粉：75g/L,染料和元明粉的用量较高,污水处理的压力很大,而且所述锦棉梭织物活性酰胺染料一浴法染色方法比较适合锦纶含量在20～50％范围内的织物,而对锦纶含量50％以上的锦棉效果不佳,色差较明显。
发明内容
因此,针对以上内容,本发明提供一种锦棉一浴法染色方法,解决了现有技术染料、元明粉用料较高,污水处理难度较大,且对锦纶含量50％以上的锦棉染色效果不佳的缺点。
为达到上述目的,本发明是通过以下技术方案实现的：
一种锦棉一浴法染色方法,其步骤为：
(1)坯布准备
准备机织胚布,其中锦纶含量60-80％,棉的含量20-40％；
(2)前处理
水浴比1:10,依次加入30％双氧水5-10g/L,过氧化氢稳定剂0.5-1.5g/L,所述过氧化氢稳定剂由硅酸钠:硫酸镁:EDTA＝1:1:1复合而成,净棉酶1-2g/L,控制水浴温度90-98℃,搅拌均匀后进行漂洗,时间20-30min,然后排掉漂洗液,重新注入水,水浴比1:10,加入醋酸,调节pH值至6.5-7,加入脱氧酶,用量
0.05—0.1g/L,温度30℃-50℃,处理时间10-20分钟,排掉废液,得到中性胚布；所述净棉酶加入水浴前先用70-80℃的热水化开,10min后加入冷水调至温度30-35℃备用；
(3)染色
采用东成染色机械有限公司生产的常压振荡染色机进行染色,染色处方为渗透剂H-95 0.5-1g/L,阻染剂ERIONAL RF 1.0-2.0g/L,磷酸二氢钠1.0-2.0g/L,食盐20-35g/L,匀染剂LD-VRD 0.2-1％,优丽素染料1-2％,Novacron LS型染料1-2％,纯碱5g/L,浴比1∶10,过程如下：注水,达到所述液比,水温60℃,送入所述中性胚布,加入所述染色处方中的渗透剂、阻染剂、磷酸二氢钠、食盐量的一半、染料,以磷酸二氢钠和纯碱调节pH值为5.5-6.5,染色事件持续30分钟后,加入剩余食盐,再染色10-20分钟,然后提高水温至90-100℃,加入纯碱进行固色,检测pH值10-10.5,再保温染色30-40分钟,剪样对色合格后,排掉染液,进入下一步；
(4)皂洗
加水至水浴比1:6,加入中性皂洗剂1.5g/L,在70-80℃处理30-50min,出布；
(5)开幅烘干
采用绍兴恒元机械制造有限公司生产的HYTM-8000滚筒式自动连续烘干设备进行烘干处理；处理速度：50-60m/min,处理温度为150-170℃；
(6)定型
采用德国门富士纺织机械有限公司生产的MONFONGS328-8F型定型机进行定型；定型过程中加入高浓起毛剂HLD-S7725 10-20g/L,棉锦柔软剂HLD-S772210-20g/L,硅树脂RX-852N 10-20g/L,车速：35m/min-40m/min,温度为170℃-180℃,落布门幅为149cm-150cm。
(7)成品检验
对织物的外观质量和内在质量指标进行检验,测试色牢度、锦纶和棉的色差值,所测试色牢度包括：(1)耐汗渍色牢度,按GB/T 3922—1997《纺织品色牢度试验耐汗渍色牢度》测试；(2)耐摩擦色牢度,按GB/T 3920—1997《纺织品色牢度试验耐摩擦色牢度》测试；(3)皂洗牢度,按GB/T 3921—1995《纺织品色牢度试验耐皂洗牢度》测试；4)日晒牢度,按AATCC16—2004《耐光色牢度》在耐光牢度仪上晒20h。
进一步的改进是：所述染色处方为渗透剂H-95 0.5g/L,阻染剂ERIONAL RF 2.0g/L,磷酸二氢钠2.0g/L,食盐35g/L,匀染剂LD-VRD 0.5％,优丽素蓝2R染料1.5％,NovacronLS型染料1.5％,纯碱5g/L。
进一步的改进是：定型过程中加入高浓起毛剂HLD-S7725 10g/L,柔软剂HLD-S7722 10g/L,硅树脂RX-852N 10/L。
通过采用前述技术方案,本发明的有益效果是：
1.本发明通过双氧水漂洗后使用脱氧酶去除多余的过氧化氢,使织物表面没有氧化、还原物质,保持织物表面呈中性,不会影响后续活性染料的有效作用,选用的活性染料既含有双活性基团的活性染料的成分,又含有金属络合离子的中性染料的成分,活性染料与纤维素纤维以共价键结合上染,中性染料中带负电荷的金属络合离子能与锦纶纤维上的氨基(—NH+)以离子键结合上染,具有同时上染两种纤维的特点,保证了一浴即可完成染色；本发明的前处理过程不需要多次洗涤,节省水资源,染色过程中食盐份两次加入,对棉纤维起到促然的作用,比现有工艺中一次加入促染更能减少对锦纶的影响,保障锦纶和棉纤维染色的一致性,而且食盐和染料的用料较少,节省资源,有益于环保。
2.复配的过氧化氢稳定剂,无论在室温和高温水浴中,都能达到良好的稳定效果,EDTA起到去除重金属离子的作用,硅酸钠和硫酸镁起到吸附水浴中的金属离子的作用,三者共同起作用避免过氧化氢过快分解,不会影响纤维的强度。
具体实施方式
以下将结合具体实施例来详细说明本发明的实施方式,借此对本发明如何应用技术手段来解决技术问题,并达成技术效果的实现过程能充分理解并据以实施。
