Description

一种木棉纤维纺织品的阳离子改性染色方法 Cationically modified method of dyeing textile fibers kapok

技术领域 FIELD

[0001] 本发明涉及一种改性染色方法,尤其是涉及一种木棉纤维纺织品的阳离子改性染色方法。 [0001] The present invention relates to a modified dyeing method, particularly to a cationically modified silk cotton dyeing textile fibers method.

背景技术 Background technique

[0002] 木棉纤维是木本植物木棉树的果实纤维,附着于木棉蒴果壳体内壁,由内壁细胞发育、生长而成。 [0002] kapok fiber is cotton tree fruit woody plant fibers, kapok capsule attached to the housing wall, the inner wall of cell development, has been grown. 木棉纤维与果实附着作用力小,因而一般不需专门的初加工设备,只需萝筐筛动,木棉种子便可自行沉底,即可获得木棉纤维。 Kapok fruit fiber and small adhesion force, and therefore generally do not need a special processing equipment early, simply moving the sieve basket dill, kapok seed itself can sink to the bottom, kapok fiber can be obtained. 木棉纤维具有绿色生态、中空超轻、保暖性好、天然抗菌、吸湿导湿等许多天然特性。 Kapok fibers having a green, hollow lightweight, good warm, natural antibacterial, moisture absorption and conductivity, and many other natural properties. 但是,木棉纤维因其长度短、强度低、抱合性差和缺乏弹性而难以单独纺纱,这些不足制约了其在纺织服装方面的应用和发展。 However, kapok fiber because of its short length, low intensity, poor cohesion and inflexible and difficult to separate spinning, these deficiencies restrict its application and development in the textile and clothing. 目前已有人利用木棉纤维与其他纤维混纺生产出具有极好保暖性能的保暖内衣,其成品具有超高保暖、强力快速导湿、贴身更薄软、更轻盈四大特色,并有一定数量上市,但仍存在着染色及后整理诸多问题。 Some people use kapok fiber has been blended with other fibers to produce thermal underwear has excellent thermal properties, the finished product has ultra-warm, strong fast turn wet, soft next to the skin is thinner, more lightweight four characteristics, and a certain number of listed, but there are still many problems in dyeing and finishing.

[0003] 与棉纤维相比,木棉纤维的纤维素含量明显较少,且木棉纤维具有特殊的中空形态结构和超分子结构,致使一般染料对木棉纤维的上染率很低,勻染性和上染深色效果差、 染色牢度难以得到有效提高;另外,对于木棉纤维与其他纤维的混纺、交织等产品,也容易产生染色不勻等问题。 [0003] Compared with the cotton fibers, the cellulose content is significantly less kapok fibers and kapok fibers having the special hollow morphology and supermolecular structure, resulting in low rates of dye is generally a dye kapok fiber, and uniform dyeability dark dye is poor, it is difficult to effectively improve the color fastness; Further, the kapok fiber blended with other fibers, interleaving, and other products, are also prone to problems such as uneven dyeing. 在当今人们越来越崇尚自然,追求绿色和生态纺织品的环境下,研究和开发具有独特性能的木棉纺织品就显得尤为必要。 In today's growing respect for nature, the pursuit of green and eco-textiles environment, research and development kapok textile with unique properties is particularly necessary. 但是,目前对于木棉纤维的染色性能及其染色工艺的研究报道很少,迫切需要提供一种提高木棉纤维染色性能的方法,以提高染料对木棉纤维的上染率、勻染性、染色深度和色牢度等。 However, the current study reports for dyeing properties and dyeing process of kapok fiber is small, urgent need to provide a method for improving the performance of kapok fiber dyeing, to improve dye uptake rate of kapok fiber levelness, dyeing and depth color fastness.

[0004] 纤维素纤维的阳离子改性技术能够在纤维中引入阳离子性基团或化合物,改善纤维的染色性能,大大提高各类阴离子染料的上染率,并能在染色过程中减少电解质的用量, 达到低盐或无盐染色,减少印染废水的排放量。 [0004] The cationically modified cellulose fibers technology can be introduced in a fiber compound or a cationic group, improve the dyeing properties of the fibers greatly improve the dyeing rate of various types of anionic dyes, and can reduce the amount of electrolyte in the dyeing process , to low-salt or salt-free dyeing, printing and dyeing wastewater to reduce emissions. 阳离子改性方法最早出现在棉纤维的染色研究中,主要是因为阳离子改性后纤维带正电荷,提高了阴离子染料与纤维的结合力,进而提高上染率、缩短染色时间。 Cationically modified method first appeared in the dyeing of the cotton fiber, mainly due to the positively charged cationic modified fibers improve the binding force of the fibers with the anionic dye, thereby improving the dyeing rate, shorten dyeing time. LDraper等的研究表明,阳离子改性后,可以实现直接染料、酸性染料在碱性和无盐条件下染色,且染色织物的水洗牢度、耐光牢度都有所提高。 LDraper other studies show that cationic modification, can be direct dyes, acid dyes under alkaline conditions and salt-free, and the dyed fabric washing fastness, light fastness are improved. 刘中君和郝龙云等人的研究表明,阳离子改性可用于棉织物的涂料染色,且工艺简单,粘合剂用量少,色牢度有所提高,一般在3〜4级。 Study Liuzhong Jun and Haolong Yun et al showed that the coating be used for dyeing cationic modified cotton fabric, and the process is simple, with less binder, improved color fastness, typically 3 to 4 stages. 沈勇、张惠芳等人采用自制的阳离子改性剂SA对苎麻纤维改性,研究表明阳离子改性后的苎麻纤维在溶液中负电性显著降低,提高了酸性染料对纤维的染色亲和力。 Shen Yong, Zhanghui Fang et al cationic modified self-made SA ramie fiber modification agents, studies have shown that the cationic modified ramie significantly lower negative charge in solution, to improve the acid dye affinity of the fibers. A N.Chaudhary等研究探讨了N-(3-氯-2-羟丙基)三甲胺氯化物在羊毛直接和活性染料染色中的应用,结果表明阳离子改性后羊毛的上染率和染色深度明显提高,摩擦牢度和撕裂强度没有明显变化。 A N.Chaudhary other studies have investigated the N- (3- chloro-2-hydroxypropyl) direct trimethylamine chloride and wool reactive dyeing application, results show that the dye uptake of wool dyeing depth and the cationically modified significantly increased, rubbing fastness and tear strength did not change significantly. 王潮霞等将阳离子改性技术应用于羊毛织物的超细涂料染色中,通过对改性条件的研究得出改性羊毛织物经涂料染色后,干湿摩擦牢度均有所提高,织物手感柔软,弹性良好。 Xia Chao Wang et cationic modified superfine coating technology used in the dyeing of wool fabrics, from a study of the modification conditions derived modified woolen fabrics after dyeing coating, wet and dry rubbing fastness was improved, and soft fabric, good elasticity. 王雪燕等用3-氯-2-羟丙基三甲基氯化铵对绢丝进行阳离子改性,使绢丝纤维引人更多的阳离子基团,增加了绢丝对阴离子染料染色的染座,提高了染料与纤维之间的亲和力,从而在中性浴条件下,可用活性染料、直接染料染色,不仅可缩短染色时间、减少染色酸用量,并且能够降低染色温度,实现绢丝节能、清洁化染色。 Wang Xueyan 2-hydroxypropyl trimethyl ammonium chloride and the like to silk cationic modified with 3-chloro-the silk fibers introduce additional cationic groups, increasing the anionic dye sites silk dyed improves the affinity between the dye and the fiber, so that in a neutral bath conditions, available reactive dyes, direct dyes, dyeing time can be shortened not only reduce the amount of acid dye, and the dyeing temperature can be reduced, to achieve energy saving silk, cleaning staining.

[0005] 随着阳离子改性方法的应用和发展,阳离子改性剂的种类也在不断增加。 [0005] With the application and development of cationic modified method, the kind of cation-modifier is also increasing. 阳离子改性剂按与纤维的结合方式分为反应型和吸附型。 Cationic modifying agent by binding to the fiber and reactive way into adsorption type. 反应型阳离子改性剂的分子结构中既包含可与纤维反应的活性基团,又含有可以促染的阳离子基团或氨基。 The molecular structure of the reactive cationic modifier contains both reactive groups can react with the fibers, and containing a cationic or amino groups can promote infection. 根据反应性基团的不同,可分为环氧类化合物、均三嗪基季铵盐化合物、阳离子丙烯基共聚物、氮杂环阳离子化合物。 Depending on the reactive groups can be divided into an epoxy-based compound, triazine-based quaternary ammonium compounds, cationic acrylamide-based copolymer, a cationic nitrogen heterocyclic compound. 环氧化合物在碱性条件下可与纤维素纤维反应形成醚键,使纤维阳离子化。 May form an epoxy compound is reacted with an ether-linked cellulosic fibers under alkaline conditions, cationized fibers. 均三嗪基季铵盐化合物是一类反应活性较高的阳离子改性剂,按活性基团的多少又可分为单活性单季铵盐、单活性双季铵盐和双活性多季铵盐。 Triazinyl quaternary ammonium compound is a cationic type of reaction higher activity modifier, according to the number of reactive groups can be divided into single-single quaternary, single-bis quaternary ammonium salts and bis-active polyquaternary salt. 由于此类化合物反应活性高,可以使纤维有效地阳离子化,其热稳定性好于环氧类化合物。 Due to the high reactivity of these compounds, the fibers can be efficiently cationized, good thermal stability in the epoxy compound. 双活性多季铵盐改性剂可提高其与纤维的结合力,大大减少改性剂用量。 Multi-bis-active quaternary ammonium modifier can improve the bond with the fibers, greatly reducing the amount of modifier. 阳离子丙烯基共聚物是一种反应性聚合物,可与纤维素纤维发生亲核反应,使聚合物固着在纤维上,染色过程中可发生纤维与聚合物、聚合物与染料以及染料与纤维之间的化学反应,在纤维内部形成交联,能有效地提高染料的上染率,减少染料废液的排放,也能够实现无盐染色。 Cationic acrylamide-based copolymer is a reactive polymer, the nucleophilic reaction may occur with the cellulose fibers, the polymer fixation on the fibers, polymer fibers and dyeing process may occur between the polymer and the dye, and the dye with the fiber chemical reaction, is formed in the inside of the fiber crosslinking, can effectively improve the dye uptake of the dye, the dye reduce waste discharge, it is possible to salt-free dyeing. N,N' -二甲基氮杂环丁烷氯化物(DMAC)是典型的氮杂环阳离子化合物,纤维素纤维先经碱处理,有助于形成纤维素亲核阴离子,再用DMAC 浸渍处理,增加DMAC与纤维的反应性,从而提高纤维的染色性能。 N, N '- dimethyl-azetidine chloride (DMAC) is a typical cationic nitrogen heterocyclic compound, the first base-treated cellulose fibers, contribute to the formation of cellulose nucleophilic anion, and then dipped DMAC increased reactivity with DMAC fibers, thereby improving the dyeing properties of the fibers. 吸附型阳离子改性剂是一类聚阳离子系化合物和聚胺系化合物,可直接吸附在纤维上,这类阳离子改性剂与织物的结合力弱,处理后牢度差,实际使用较少。 Cationic adsorption modifier is a class of polycationic compound and a polyamine compound, it may be directly adsorbed on the fiber, such cationic modifier to the fabric in conjunction with weak, poor fastness after treatment, use less practical.
