本发明属于织物染色方法技术领域,具体涉及一种采用阔叶十大功劳染料对竹纤维面料进行染色的方法。The invention belongs to the technical field of fabric dyeing methods, and in particular relates to a method for dyeing bamboo fiber fabrics by using broad-leaf ten mahjong dyes.
背景技术Background technique
公开该背景技术部分的信息仅仅旨在增加对本发明的总体背景的理解,而不必然被视为承认或以任何形式暗示该信息构成已经成为本领域一般技术人员所公知的现有技术。Disclosure of the background information is only intended to increase the understanding of the overall background of the present invention, and is not necessarily regarded as an acknowledgement or any form of suggestion that the information constitutes the prior art known to those of ordinary skill in the art.
自上世纪90年代起,我国纺织服装生产及出口数量已位居世界之首,在带来经济与民生发展的同时,纺织行业的污染问题也不容小觑。全球范围内,仅次于石油行业,纺织服装行业已经成为全球第二大污染行业。传统的纺织行业耗水量巨大,且生产过程伴随大量废水,印染企业排放的生产废水中夹带大量纤维、浆料、油剂、染料和化学助剂等,危害性强,处理难度高。另外,生产过程中的有毒染料或加工助剂也会附着在织物上,对人体的健康造成直接的影响,如偶氮染料、甲醛、荧光增白剂和柔软剂具致敏性;聚乙烯醇和聚丙烯类浆料不易生物降解;含氯漂白剂污染严重;一些芳香胺染料具有致癌性;染料中具有害重金属;含甲醛的各类整理剂和印染助剂对人体具有毒害作用等。Since the 1990s, my country's textile and garment production and export volume has ranked first in the world. While bringing economic and people's livelihood development, the pollution problem of the textile industry cannot be underestimated. Globally, second only to the petroleum industry, the textile and apparel industry has become the world's second most polluting industry. The traditional textile industry consumes huge amounts of water, and the production process is accompanied by a large amount of waste water. The production waste water discharged by printing and dyeing enterprises contains a large number of fibers, sizing agents, oils, dyes and chemical auxiliaries, which are harmful and difficult to treat. In addition, toxic dyes or processing aids in the production process will also adhere to the fabric, causing a direct impact on human health. For example, azo dyes, formaldehyde, fluorescent brighteners and softeners are allergenic; polyvinyl alcohol and Polypropylene slurry is not easily biodegradable; chlorine-containing bleaching agents are seriously polluted; some aromatic amine dyes are carcinogenic; dyes contain harmful heavy metals; various finishing agents and printing and dyeing auxiliaries containing formaldehyde have toxic effects on the human body.
另外,传统的印染技术中多采用碱性试剂对面料进行预处理,这些处理过程对于面料本身的外观和使用感受也会造成不良影响。为了实现环保生产,提高面料的舒适程度,将生物酶应用于纺织印染具有显著的优势,包括清洁织物表面、减少表面绒毛,改善织物的手感性能、悬垂度、吸水性等。同时生物酶处理工艺还兼具环保性的特点,可以有效地降低污水处理的需氧量,与强碱和强化剂相比,生物酶无疑是一种无污染的环保性较高的工具,可以有效处理染色前处理煮漂废液,而且不会造成二次污染。In addition, in traditional printing and dyeing techniques, alkaline reagents are often used to pre-treat fabrics, and these treatment processes will also have a negative impact on the appearance and use experience of the fabric itself. In order to achieve environmentally friendly production and improve the comfort of fabrics, the application of biological enzymes to textile printing and dyeing has significant advantages, including cleaning the surface of the fabric, reducing surface fluff, and improving the feel, drape, and water absorption of the fabric. At the same time, the biological enzyme treatment process also has the characteristics of environmental protection, which can effectively reduce the oxygen demand of sewage treatment. Compared with strong alkalis and enhancers, biological enzymes are undoubtedly a pollution-free and environmentally friendly tool. Effectively treat the pre-dyeing bleaching waste liquid without causing secondary pollution.
阔叶十大功劳(Mahonia bealei(Fort.)Carr.)为双子叶植物纲、小檗科、十大功劳属植物,具有广泛的药用功效。其主要成分包括小檗碱,作为广谱抗菌药物之外,还是具有阳离子化学结构的植物染料,专利CN102604423B中提供了一种以小檗碱类植物作为原料的染料提取方法,应用于腈纶纤维的染色,在获取色 彩的同时,还能够具有一定的抗菌性能。Mahonia bealei (Fort.)

The colors dyed by the mordant are yellow-white and green. The light-colored colors can better meet the needs of home wear design and bring great freedom to the design of home wear.
(2)在工艺上,大部分植物染色工艺简单,使用粉碎后的干染材和简单的媒染技术进行调色和固色,主要的几种染料材料由于是中药,可以使用干燥保存,便于运输与使用,这些均为植物染色的规模化生产提供了很好的基础,更加提高生产效率。(2) In terms of technology, most plant dyeing processes are simple, using crushed dry dyeing materials and simple mordant technology for toning and fixing. Since the main dye materials are traditional Chinese medicines, they can be dried and stored for easy transportation. And use, these all provide a good foundation for the large-scale production of plant dyeing, and further improve the production efficiency.

Although there are technologies such as crushing and ultrasonic extraction to improve efficiency, they are still not as economical as chemical dyeing. However, because plant dyeing is a high value-added process, the market value is high.
(4)从染料来源来看,阔叶十大功劳是属中药材,现在中药材产业前景良好,中药种植兴盛,让植物染料的种植走在了一个很好的发展平台上。(4) From the point of view of the source of dyes, the top ten maisons of broadleaf belong to Chinese medicinal materials. The Chinese medicinal materials industry has good prospects and the prosperous cultivation of Chinese medicines has allowed the planting of plant dyes to be on a good development platform.
(5)从环保角度上看,植物染色是染色这个污染最严重的纺织工业环节中减少污染的有效手段,且植物染色的绿色性更容易被消费者认可和接受。(5) From the perspective of environmental protection, plant dyeing is an effective means to reduce pollution in the most polluted textile industry, and the greenness of plant dyeing is more easily recognized and accepted by consumers.

从以上表格分析得出:From the analysis of the above table:
①使用盐做助染剂,染色竹纤维面料的耐摩擦色牢度较直接染色有所改善,且分别在酸碱汗液的浸渍下,沾色程度有所改善,K/S值和面料抗菌性均高于直接染色。①Using salt as a dyeing aid, the color fastness to rubbing of the dyed bamboo fiber fabric is improved compared with direct dyeing, and the staining degree is improved under the immersion of acid and alkali sweat respectively, the K/S value and the antibacterial property of the fabric Both are higher than direct dyeing.
②使用明矾、硫酸亚铁做媒染剂对竹纤维面料进行染色后,虽然面料的K/S值高于直接染色,但面料抗菌性略低于直接染色,染色后的色牢度不太理想。②After dyeing bamboo fiber fabric with alum and ferrous sulfate as mordant, although the K/S value of the fabric is higher than that of direct dyeing, the antibacterial property of the fabric is slightly lower than that of direct dyeing, and the color fastness after dyeing is not ideal.
③媒染后的竹纤维织物色牢度不太理想,所以最终染色实验不选用明矾、硫酸亚铁媒染。③The color fastness of the bamboo fiber fabric after mordant dyeing is not ideal, so alum and ferrous sulfate mordant dyeing are not used in the final dyeing experiment.
④盐做助染剂,不仅提高面料的色牢度,且面料抗菌性较其他染色方法也有所提高,K/S值较直接染色也有所提高。④Salt is used as a dyeing aid, which not only improves the color fastness of the fabric, but also improves the antibacterial property of the fabric compared with other dyeing methods, and the K/S value is also improved compared with direct dyeing.
最终选用盐作助染剂对竹纤维面料进行染色。Finally, salt is used as a dyeing aid to dye bamboo fiber fabrics.
