Description

一种染色布料及其染色方法 技术领域
本发明涉及印染领域，特别涉及一种染色布料及其染色方法。
背景技术
目前的布艺染整工艺只能将布样染成同一颜色，或者根据不同纤维的编织位置染成特定的颜色分布，并且这种颜色、图案是预先设定、统一、死板不可变的；如果需要更多或更复杂图案时，一般采用印花工艺，但是印花后的图案比较死板，无法实现自由、个性化的需求；同时图案会突出，难和布样形成平整一致的感觉，并且印花工艺需要复杂及耗时的工序。
发明内容
为此，需要提供一种可以满足自由、个性化需求的颜色、图案的布料及其相应的染色方法。
为实现上述目的，发明人提供了一种布料的染色方法，包括以下步骤：
进料：将布料放置于染槽内，所述布料沿染槽的水平方向层叠放置，
染色：将染液放入染槽，对布料进行静态染色，所述布料部分浸入染液中，布料位于染液上方的部分通过毛细作用吸收染液，呈现出渐进的花色效果。
进一步地，所述布料包括已染色布料和坯布。
进一步地，所述坯布在进料前进行热洗。
进一步地，所述染色过程使用静态染色法，在染色过程中，染液处于静止状态，使得印染过程中花型稳定。
进一步地，所述染色步骤中，染色的浴比为1:5-10。
进一步地，所述染色步骤中，染液进入染槽后升温至布料的染色固色温度；染液的升温速率为1.0-2.5℃/min。其中布料染色的染固色温度、时间 按布料的材质或染料的类型进行调整。
进一步地，还包括后处理步骤，所述后处理步骤中，染液放出染槽前进行降温，降温速率为1.0-2.0℃/min
进一步地，染色过程使用高温溢流染色机。
发明人还提供了一种染色布料，所述染色布料采用以上任一所述的方法进行染色。
区别于现有技术，上述技术方案提供了一种染色方法，该染色方法通过将布料沿染槽的水平方向层叠放置，槽内染液高度低于布料高度，使得布料部分浸入染液中，在染色过程中，染液上方的布料未被染液直接浸染到，该部分布料的布料纤维通过毛细作用吸收下部的染液，并呈现出渐进的、深浅不一的染色效果或一定的露白的效果，有朦胧的美感。该部分间接染色或未染色部分的布料最后呈现的颜色和图案都各不相同，具有独特、无可复制性，满足现代人自由、个性化的需求。同时该染色方法，具有良好染色稳定性，可应用于各种不同布料的染色。
