Description

一种环保节能的数码印花工艺
技术领域
本发明涉及一种数码印花工艺，尤其涉及一种环保节能的涂料数码印花工艺。
背景技术
近年来，印染行业的环保节能要求越来越严格。虽然国内现在开始用数码印花替代一部分传统染色方式，也确实更环保化，也能符合现在越来越多小批量、多品种、定制化等需求。
一般的数码印花工艺比较传统大幅降低了染料墨水的使用和浪费，但是仍然会存在部分的浪费。本发明专利主要介绍了一种涂料数码印花工艺，简化生产工序、无水洗和污水排放，真正达到了环保节能的需求。而且通过此工艺，有效改善提高了涂料数码印花色彩不够鲜艳、干湿摩擦牢度不好的缺点。
发明内容
本发明要解决的技术问题是根据不同面料的数码印花，优化涂料数码印花工艺。为了能提高改善印花后色彩颜色、色牢度等问题，本发明对面料进行了预处理，根据不同面料采用合适的涂料墨水和优化工艺参数，还有后处理工艺。本发明工艺工序为：面料预处理—墨水选择—直喷印花—烘干—焙烘—后处理—烘干—成品，具体步骤如下：
(1)面料预处理：面料未经柔软整理，通过等离子体处理，功率50～100W，压强40～80Pa,时间5～15min。
(2)墨水选择：由OCS墨水智能选择控制***，根据面料成分进行选配。
(3)直喷印花：直接对预处理后的面料进行喷墨打印。
(4)烘干：经过印花后的面料放在烘定机上烘干，烘箱温度为100～120℃，超喂10％～30％，拉幅5％～15％，车速10～20m/min。
(5)焙烘：温度为150～180℃，超喂10％～30％，拉幅5％～15％，车速10～ 20m/min。
(6)后处理：根据需要进行后处理工艺，通过二浸二轧，将助剂作用于布面，达到处理效果，包括固色整理、柔软整理、三防整理、抗菌整理等。
(7)烘干：经过后处理的面料放在烘定机上烘干，烘箱温度为100～120℃，超喂10％～30％，拉幅5％～15％，车速10～20m/min。
进一步地，当所述面料为聚酯纤维纯纺或混纺的织物时，所述步骤(1) 和(2)之间还包括湿喷处理，采用聚乙二醇溶液对所述聚酯纤维织物进行湿喷处理，所述聚乙二醇溶液的浓度为80～120g/L。
进一步地，所述步骤(2)中，不同面料成分的不同智能匹配墨水；除锦纶和腈纶外的化纤面料，采用分散墨水，除丝绸外的蛋白质纤维、锦纶、腈纶面料采用酸性墨水，棉、麻及粘胶类的再生纤维素纤维、丝绸采用活性墨水。
进一步地，所述步骤(6)中的具体后处理方式包含但不限如下：
(1)固色整理：无醛固色剂WPB,1-5％；浴比1:10-20；温度40-50℃；车速5-8米/分钟；
(2)柔软整理：生物酶配方柔软剂5-8g/L；浴比1:8-15；温度55-60℃；车速15-20米/分钟；
(3)三防整理：特氟龙三防助剂5-6％，50g/L；冰醋酸0.5-1.5g/L；渗透剂WDN 0-5g/L；浴比1:8-15；温度55-60℃；车速15-20米/分钟；
(4)抗菌整理：TN30抗菌助剂，用量为布重2％-4％；车速15-20米/分钟。
本发明的有益技术效果在于：
对常规涂料数码印花前进行预处理，根据面料成分选择对应的墨水；后处理中进一步对印花后的面料进行固色整理，保证颜色牢度得以提高改善。同时，该印花工艺采用YH8585型大圆机数码印花设备，不仅限于裁片类的涂料印花，而且适用于匹装成卷面料的印花。
(1)预处理采用等离子体方式对面料表面进行改性处理，来提高面料印花后的墨水色泽度以及牢度。该工艺代替了常规增稠剂的湿法处理，减少了化学品的使用，避免废水污染，也降低了能耗浪费。
(2)对于聚酯纤维面料的预处理，额外采用聚乙二醇对面料进行直喷处理，提高面料亲水性和有效上染率。同时，代替常规浸压方式，直接采用直喷处理，避免湿态浪费和污染，减少预处理周期的等待时长。
(3)预处理后直接喷墨打印，避免再次烘干，减少工序降低能耗，也能提高预处理对于打印上色效果的有效性。
(4)通过预处理和固色后处理的涂料数码印花面料，色泽鲜艳度更好，干湿摩擦牢度也得到了明显的提高。由于涂料印花工艺可以适用于各类面料，经过工艺改善，有利于涂料数码印花的广泛应用。
