Description
技术领域
本发明涉及纺织印染技术领域,具体涉及一种免浆处理的真丝织物数码印花方法。
背景技术
随着经济的快速发展,对服装的主流消费逐渐趋于个性化、时尚化,服装的花型新颖独特、变化丰富多样。印染加工厂印花产品种类更加多样,数码印花的出现和发展满足了小批量、多品种的生产方式。然而,数码印花又区别于筛网印花,织物在印花前必须经过预处理,既能防止墨水喷印在织物上的渗化,又能为墨水的发色固色提供应有的条件,改善织物对墨水的吸附性和固着性。
在真丝织物数码印花预处理的方法中,通常采用浆料如海藻酸钠、pink浆、CMC(羧甲基纤维素)等处理织物,以达到防止织物花形渗化的目的。而在真丝上浆处理过程中,易在织物上形成浆斑、纬斜等问题,造成生产质量下降。经上浆处理后的真丝织物手感***,即使经过皂洗阶段,依然会在织物上残留少量浆料,使真丝织物自身的柔软舒适性的特点大打折扣。并且,在皂洗废液中含有较多氨氮,造成污染,不利于环保。
发明内容
本发明的目的在于针对现有技术存在的缺陷和不足,提供了一种免浆处理的真丝织物数码印花方法。本发明方法新颖独特,操作工艺流程简单,经免浆处理的真丝织物喷印花形精细,织物手感柔软度高。相比于现有的上浆处理工艺,可以减少生产过程中的质量问题,减小污染,有利于绿色环保。
本发明的目的是通过以下技术方案来实现的:一种免浆处理的真丝织物数码印花方法,该方法包括以下步骤:
(1)制备印花前液,所述印花前液中,各组分的重量百分比含量如下:
(2)浸轧织物:将真丝织物浸渍在印花前液中,真丝织物与印花前液的重量配比为1:30,5分钟后,再对织物轧压脱液,轧余率100%;
(3)烘干:步骤1处理后的真丝织物在60℃下烘10分钟;
(4)数码喷印:在25℃,60%相对湿度的环境下,以720×720dpi分辨率、4pass通道打印图案;
(5)预烘:将经数码喷印后的真丝织物于60℃下预烘10分钟;
(6)汽蒸固色:将预烘后的真丝在100-120℃下汽蒸15-45分钟;
(7)皂煮后处理:80℃下皂煮5分钟,皂洗剂中含有2-5g/L的皂片和0-5g/L的碳酸钠,溶剂为水;
(8)烘干:将皂煮后的真丝织物在60℃烘干。
进一步地,所述有机氟类防水剂可以选用全氟烷烃类防水剂EPF、全氟C8防水剂5672等。
进一步地,所述有机硅类柔软剂可以选用二甲基硅油柔软剂PMX-200、三元共聚有机硅柔软剂MF-781等。
进一步地,所述步骤(6)中采用圆筒蒸化机汽蒸,所需蒸汽为过饱和蒸汽。
本发明的有益效果为:在真丝织物预处理中免去了上浆的过程,使后处理水洗工序的效率得到提高;配方中尿素用量的下降,也大大减少氨氮的排放量;整体的工艺流程因不需要糊料成糊搅拌,操作简单、方便;同时大大改善了上浆过程中出现的浆斑、纬斜、匹差等问题。经免浆处理的真丝织物手感柔软、滑爽,花纹精细度清晰。

对比例1:
真丝织物数码印花的上浆工艺方法,其工艺配方各组分按重量百分比含量如下:
真丝织物的数码印花上浆工艺的操作工艺流程如下:
(1)印花浆液的制备:按比例称取各成分,搅拌均匀后,放置第二天使用。

可见,本发明的方法大大改善了上浆过程中出现的浆斑、纬斜、匹差等问题;且经免浆处理的真丝织物手感柔软、滑爽,花纹精细度清晰。
以上所实施例是对本发明技术方案的具体说明,并非对本发明做任何形式上的限制。本领域内的技术人员对本发明技术方案做其他修改/替换,在未超出权利要求记载的技术方案的前提下,均应涵盖在本发明的权利要求范围当中。
