Description
技术领域Technical field
本发明涉及纺织品加工领域，特别涉及一种染整工艺。 The invention relates to the field of textile processing, in particular to a dyeing and finishing process.
背景技术Background technique
由于竹纤维的特殊性，如果沿用棉纺织品的染整工艺，就会使得竹纤维的天然抗菌性能急剧下降。竹棉混纺织物染色后，需要对竹棉混纺织物进行染色后的处理，染色后处理的工序对竹棉混纺织物的品质影响非常大。目前现有的染色方法处理后竹棉混纺织物的色牢度并不是很高，并且现有的染色后处理方法也比较耗能。因此，需要提供一种新的技术方案来解决上述问题。Due to the particularity of bamboo fiber, if the dyeing and finishing process of cotton textiles is followed, the natural antibacterial property of bamboo fiber will be drastically reduced. After dyeing the bamboo-cotton blend fabric, it is necessary to dye the bamboo-cotton blend fabric after dyeing, and the post-dye treatment process has a great influence on the quality of the bamboo-cotton blend fabric. At present, the color fastness of the bamboo-cotton blended fabric after the existing dyeing method is not very high, and the existing post-dyeing treatment method is also relatively energy-intensive. Therefore, it is necessary to provide a new technical solution to solve the above problems.
发明内容Summary of the invention
本发明要解决的技术问题是提供一种染整工艺。The technical problem to be solved by the present invention is to provide a dyeing and finishing process.
为解决上述技术问题，本发明的技术方案为：一种染整工艺，其创新点在于：包括下述步骤：In order to solve the above technical problem, the technical solution of the present invention is: a dyeing and finishing process, which is innovative in that it comprises the following steps:
煮漂：配置煮漂液，将低温练漂助剂组合物、双氧水、烧碱、稳定剂及抗皱剂加入水中制成煮漂液；染色：调节煮漂液至pH为7，取出竹棉混纺织物并同染液一起置于染色机中，每升染液16g的量加入纯碱，染液温度先加热到97℃并保持25min，染液温度再加热到130℃并保持45min，然后冷却至71℃，进行缓慢固色；清洗还原：将清洗液加入染色机中，在7℃的温度下洗涤35min；Boil and rinse: configure the boiling and bleaching liquid, add the low temperature bleaching aid composition, hydrogen peroxide, caustic soda, stabilizer and anti-wrinkle agent to the water to make the boiling liquid; dyeing: adjust the boiling liquid to pH 7, remove the bamboo and cotton blend fabric And put it together with the dyeing solution in the dyeing machine, add soda ash per liter of dyeing solution 16g, the temperature of the dyeing liquid is first heated to 97 ° C and kept for 25min, the temperature of the dyeing liquid is heated to 130 ° C and kept for 45min, then cooled to 71 ° C , to carry out slow fixation; cleaning and reduction: the cleaning solution is added to the dyeing machine, and washed at a temperature of 7 ° C for 35 minutes;
d）后处理：清洗还原后的竹棉混纺织物置于冰醋酸浴中，升温到65℃保温15分钟，常温水洗。。 d) Post-treatment: The washed bamboo-cotton blended fabric is placed in a glacial acetic acid bath, heated to 65 ° C for 15 minutes, and washed at room temperature. .
本发明的优点在于：利用纯碱进行染色，碱耗用成本低，用量少，浴液中化合低聚物就少，可节省整个工艺的染色时间，有利于节水环保，染色过程温度分段上升，再保持一定的时间，然后71℃的还原清洗温度，提高了竹棉混纺织物的色牢度，冰醋酸浴后整理工艺保证了织物的强力，最终生产的织物表面平整，色泽均匀，染料色牢度高。The invention has the advantages that: the dyeing by the soda ash, the alkali consumption cost is low, the dosage is small, and the oligomer in the bath liquid is less, the dyeing time of the whole process can be saved, the water saving environment is favorable, and the temperature of the dyeing process is segmented. Rise, and then maintain a certain period of time, then the reduction cleaning temperature of 71 ° C, improve the color fastness of the bamboo and cotton blend fabric, the glacial acetic acid bath finishing process to ensure the strength of the fabric, the final production of the fabric surface is flat, uniform color, dye High color fastness.
针对纺织品染色后处理，不同于常规皂洗处理方法，而是通过一种生物酶作用于水中和纤维表面未固着染料结构中的发色基团，从而加速分解反应，使后处理残液脱色，达到消色目的，对已经与纤维织物通过共价键结合的染料无任何影响，不影响色光，各项牢度指标均可达到国家对纺织品质量要求标准，让染色后处理工艺变得简单，缩短处理时间，减少水洗次数从而降低废水排放量，达到了节水、节能、省时、高效的目的。For the textile dyeing post-treatment, unlike the conventional soaping treatment method, the chromogenic group in the dye structure in the water and the fiber surface is not fixed by a biological enzyme, thereby accelerating the decomposition reaction and decolorizing the post-treatment residual liquid. To achieve the purpose of decolorization, it has no effect on the dyes that have been covalently bonded with the fiber fabric, and does not affect the color light. The fastness indicators can meet the national quality requirements for textiles, making the post-dye treatment process simple and shortened. Processing time, reducing the number of washings to reduce the amount of wastewater discharge, achieving the goal of saving water, saving energy, saving time and high efficiency.
