Description
本发明涉及纺织领域,特别是涉及一种新的生产具有保健功能纯天然染色纤维的方法。
纤维传统的常用染色方法包括原液染色和散纤维染色。原液染色是指在聚合加工过程中或过程后,在纺丝前加入着色剂制成有色纤维。散纤维染色是利用散纤维染色机对棉花或其他纤维直接进行染色,纤维在染缸内静止不动,染液凭借主泵的输送,不断从染缸内层向外层在纤维间穿透循环,使染料均匀上染散纤维。无论原液染色、还是散纤维染色,目前两类染色工艺使用的染料大多数是化学染料,染料和纤维的染色本质,都需在温度、pH值、时间和助剂等特定介质环境下的相互作用下,完成纤维染色的上染和固色,生产过程中必须使用化工染料和酸、碱、还原剂、氧化剂、电解质或表面活性剂等化工助剂,这些化学染色方法根本谈不上纯天然染色。即使近期散纤维染色中开始部分使用天然染料进行染色、但染色过程中仍然需要使用化工助剂配合才能生产出质量达标的染色产品,因为染色后纤维的色牢度指标很多仍达不到国家相关质量标准的要求,便采用对上染物进行改性后染色、媒染法染色、合成固色剂等方法来提高天然染料的染色牢度,但加入化工助剂后、失去真正意义上的天然染料的“绿色 性”及其染色加工过程中的“环保性”;原液染色至今也依然没能实现纯天然染色,更不具有天然保健功能了。
对纤维而言,目前还没有一种方法使用的染料全部是纯天然染料,而且能够以工业化的方式进行纤维的纯天然染色的同时染色后纤维还具有保健功能。为满足高端消费者对保健功能纯天然染色产品的需求,而且生态纺织品的设计必须使用到高品质的天然功能性的有色纤维,才能以更多不同比例和工艺混合制得更丰富、更健康的纱线和服装产品,因此提供一种新的生产具有保健功能纯天然染色纤维的方法很有必要。
发明内容

本发明的技术方案:
一种新的生产具有保健功能纯天然染色纤维的方法,对纤维进行原液染色生产,包括以下步骤:S1.染色染料的选择;S2.染色染料的配置;S3.纺丝前准备,制备成粘稠的纺丝溶液、纺丝;S4.纺丝后处理;S5.天然染色;S6.染色后处理;
步骤S1中选择的染色染料中至少有一种高粘度天然染色染料,其他的染色染料为普通天然染色染料,其中高粘度天然染色染料占染色染料总量的5~100%;

步骤S4中的纺丝后处理包括但不限于如下步骤:水洗、脱硫、水洗、酸洗、水洗以及烘干;
步骤S5中的天然染色包括但不限于如下步骤:将S2中的纯天然染色液加入染色槽内,以轧染的方式对水洗并烘干后的纤维丝束进行染色;
步骤S6中的染色后处理包括但不限于如下步骤:预烘干已经染好色的纤维丝束、水洗、烘干、上油、烘干以及打包。
所述高粘度天然染色染料包括但不限于野山果薯莨浓缩液、凤眼果浓缩液和菠萝蜜浓缩液。
步骤S5后不能马上进行水洗,而是进行步骤S6。
一种新的生产具有保健功能纯天然染色纤维的方法,对纤维进行散纤维染色生产,包括以下步骤:S1.染色染料的选择;S2.染色染料的配置;S3.配棉;S4.散纤维入缸;S5.精练前处理;S6.染色前的脱水、烘干;S7.天然染色;S8.脱水、预烘干;S9.水洗;S10.烘干;S11.打包;
步骤S1中选择的染色染料中至少有一种高粘度天然染色染料,其他的染色染料为普通天然染色染料,其中高粘度天然染色染料占染色染料总量的5~100%;
步骤S2在制成的纯天然染色液中茶多酚的含量检测指标至少30%,并进行染色液萃取,得到纯天然染色液;

经过步骤S7中所述的天然染色后,散纤维不能马上进行水洗,而是进行步骤S8所述的脱水、预烘干,先预烘干已经染好色的散纤维,利用高粘度天然染色染料自身的粘性将纯天然染色液中的有效成分与纤维粘着固牢,并将茶多酚固着在纤维上,然后进入步骤S9中所述的水洗、将染色的浮色清洗干净,再进入步骤S10中所述的烘干,将纯天然染色液中的茶多酚和其他有效成分与纤维再次粘牢,最后进行步骤S11,完成整个染色过程。
其中:高粘度天然染色染料的粘度为10-2000(单位:CP厘泊)。
