Description

一种具有同色深浅效应的色纱生产方法 技术领域
本发明涉及色织布生产技术领域,具体涉及具有同色深浅效应的色纱的生产技术。
背景技术
花灰纱特有的梦幻般的朦胧效果使其附加值较高,一般多用于制作高档面料。其生产方法有多种,但是大多数是采用混纺得到。例如:采用有色纤维与本色纤维进行混纺,得到如“派力司”形式的花灰效果;也可以采用捻线机将一根本色纱和一根色纱合股成线,用该线织成的织物也可得到花灰效果。但是由于染色纱/纤维与本色纱/纤维可纺性质差别很大,而且灰色的深浅较难控制,使得该纱线试纺难度较大,对工艺、设备、操作等管理和质量要求都非常严格。
近年来,为了解决这一问题,有部分厂家利用纤维染色性能的差异,在纺纱时将两种染色性能各异的纤维进行混纺,织成织物后只对其中一种纤维进行染色,也得到了一定的“花灰”效果,但是此类面料存在纤维两种组分间沾色严重,染色时稍有控制不当便会导致纤维对比不突出,最终导致“花灰”效果很差。
发明内容
本发明目的是为了克服以上现有技术缺陷,提出一种具有同色深浅效应的色纱生产方法。
本发明技术方案包括以下步骤:
1)前处理:对以纤维素为主要材质的原纱经过煮练、漂白或丝光处 理;
2)浆纱:将高糊化淀粉与分色剂混合进行调浆,取得浆料后对经过前处理的原纱进行上浆,最终得到上浆率为4~18%的上浆经纱;
3)染色:分别采用活性染料、靛蓝染料或者还原染料中的任意一种对上浆经纱进行染色;
4)后处理:采用淀粉酶退浆或者碱退浆中任意一种方法对纱线进行退浆。
本发明利用分色剂对染料的阻染性能,利用以高糊化淀粉将分色剂均匀分散到高糊化淀粉浆料中,通过上浆工艺施加到纱线表面。这样它们就可以均匀散布在纱线表面,进行染色时,其覆盖的区域就会因为阻染而形成白斑或者染色较浅的过渡区域,染色后再经过退浆流程去除分色剂,从而就在纱线上制造出深浅不一的“花灰”效果。
本发明的优点和效果:为了降低传统花灰纱纺制时存在颜色深浅难控制,试纺难度大,对工艺、设备、操作等管理和质量要求都非常严的问题,本发明通过在纱线上浆工艺中施加具有阻染能力的分色剂来实现纤维素类纱线的花灰效果。所采用的分色剂是一种含氮化合物,具有施加方便,遮盖力强,而且容易去除的优点。上浆时,分色剂可以通过高糊化淀粉与经纱紧密结合,均匀地散布在经纱表面,这些散布的分色剂在纱线染色时便可以阻止染料对其所覆盖区域的上染,在一根纱线上形成深浅不一的染色效果。染色后的纱线,可以直接退浆得到花灰纱,也可以直接利用织造,织造完成后再退浆即可显现花灰效果。
本发明原纱材料选材范围广,所述原纱为棉、粘胶、天丝或麻中的任意一种。采用这些材料都能取得良好效果。
所述步骤2)中,所述浆料中分色剂占浆料总质量的1~30%。在这个比例区间内,因其阻染得到的深浅不一的“花灰”效果比较明显。
所述步骤2)中,所述分色剂为十八胺聚氧乙烯醚AC-1860或德司达Sera Fast XP903。这些材料都是已商业化应用的产品,性能稳定,方便生产,利于降低生产成本。
所述步骤2)中,调浆时的温度为90~130℃。该温度下,可使淀粉与分色剂更均匀地分散、糊化,生产的混合浆料流动性较好,粘附力较高,可以将分色剂足量均匀的分布在纱线表面,有助于获得深浅不一的均匀“花灰”效果。
所述步骤2)中,上浆温度为50~90℃。该上浆温度下,混合浆料流动性较好,粘附力较高,可以将分色剂足量均匀的分布在纱线表面,有助于获得深浅不一的均匀“花灰”效果。
所述步骤3)中,所述染色采用的染料种类为活性染料、靛蓝染料或者还原染料中的任意一种。活性染料以及还原染料的采用可以极大丰富花灰纱的色彩范围,而且使其拼色难度大大降低。
具体实施方式

然后采用还原金黄GK对其进行染色,完成后采用碱退浆进行处理即可得到深浅不一具有金黄色花灰效果的色纱。
实施例3:
纯棉原纱经过煮练、漂白以及丝光等前处理后,整经后进行浆纱,其工艺如下:按照浆料总量10%的质量比例添加分色剂(主要成分德司达Sera Fast XP903),并在100℃下调浆10秒,混匀后于80℃上浆,最终获得上浆率11%的经纱。
然后采用靛蓝对其进行染色,完成后采用碱退浆进行处理即可得到深浅不一具有靛蓝色花灰效果的色纱。
实施例4:
纯棉原纱经过煮练、漂白以及丝光等前处理后,整经后进行浆纱,其工艺如下:按照浆料总量1%的质量比例添加分色剂(主要成分十八胺聚氧乙烯醚AC-1860)),并在100℃下调浆10秒,混匀后于80℃上浆,最终获得上浆率11%的经纱。
然后采用靛蓝对其进行染色,完成后采用淀粉酶退浆即可得到深浅不一具有靛蓝色花灰效果的色纱。
