技术领域 technical field
本发明涉及纺织技术领域，具体涉及一种无甲醛的亚麻织物抗皱整理液。 The invention relates to the technical field of textiles, in particular to a formaldehyde-free linen fabric anti-wrinkle finishing solution.
背景技术 Background technique
亚麻布因布面细洁平整、手感柔软有弹性，穿着凉爽舒适、出汗不贴身等优点而成为各式夏令服装之面料，如外衣、衬衣、窗帘、沙发布等。但亚麻布料与纯棉布料类似，即穿着过程中及洗涤后易起皱，因此对亚麻布料进行抗皱处理非常重要。现有技术中的麻织物抗皱整理，很多是仿照棉织物抗皱整理的工艺方法，但因为麻纤维不同于棉纤维的特殊结构，整理后，纤维与整理剂交联的共价键的分布不均匀，受外力作用时应力集中现象明显，造成麻织物弹性虽然提高，但麻织物的强力损失严重，在麻织物弹性回复性能和强力之间很难达到一个好的平衡点。 Linen has become the fabric of all kinds of summer clothing, such as coats, shirts, curtains, sofas, etc., because of its fine and smooth surface, soft and elastic feel, cool and comfortable wearing, and not close to the body when sweating. However, linen fabric is similar to pure cotton fabric, that is, it is easy to wrinkle during wearing and after washing, so it is very important to perform anti-wrinkle treatment on linen fabric. The anti-wrinkle finishing of hemp fabrics in the prior art is mostly based on the anti-wrinkle finishing process of cotton fabrics, but because the special structure of hemp fibers is different from that of cotton fibers, after finishing, the distribution of covalent bonds crosslinked between fibers and finishing agents is not uniform , the phenomenon of stress concentration is obvious when subjected to external force, resulting in that although the elasticity of the hemp fabric is improved, the strength of the hemp fabric is seriously lost, and it is difficult to achieve a good balance between the elastic recovery performance and the strength of the hemp fabric.
我国专利CN101565898B中提出了一种防缩抗皱低强力损失的亚麻织物染整工艺，通过该方法处理的亚麻织物防缩抗皱性能佳、强力损伤小。但该方法中采用的抗皱整理液含有树脂交联剂，经这种抗皱整理液处理的织物在穿着和使用过程中容易释放出甲醛。甲醛是一种有毒的化学品、一种皮肤刺激剂和过敏剂，可剧烈刺激眼睛、皮肤和黏膜，更是一种致癌性物质。因此，应该开发一种无甲醛的亚麻织物抗皱整理液。 Chinese patent CN101565898B proposes a shrink-resistant, anti-wrinkle and low-strength loss flax fabric dyeing and finishing process. The linen fabric treated by this method has good anti-shrinkage and anti-wrinkle performance and less damage to strength. But the anti-wrinkle finishing liquid that adopts in this method contains resin cross-linking agent, and the fabric that this anti-wrinkle finishing liquid handles releases formaldehyde easily during wearing and using. Formaldehyde is a toxic chemical, a skin irritant and sensitizer, can severely irritate the eyes, skin and mucous membranes, and is a carcinogen. Therefore, a kind of formaldehyde-free linen anti-wrinkle finishing liquid should be developed.
发明内容 Contents of the invention
本发明提供一种无甲醛的亚麻织物抗皱整理液，应用于亚麻织物可以取得良好的抗皱效果，且强力损失小，保持纯棉织物的手感良好、穿着舒适的优点；此外，该抗皱整理液还安全环保，不会释放甲醛。 The invention provides a formaldehyde-free linen fabric anti-wrinkle finishing liquid, which can obtain a good anti-wrinkle effect when applied to linen fabrics, has small strength loss, and maintains the advantages of good hand feeling and comfortable wearing of pure cotton fabrics; in addition, the anti-wrinkle finishing liquid also has the advantages of Safe and environmentally friendly, will not release formaldehyde.

优选地，一种无甲醛的亚麻织物抗皱整理液，所述抗皱整理液成分如下：每1L抗皱整理液中包含丝素整理液35g，磺羧酸型水溶性聚氨酯20g，丙烯酸羟乙酯2.5g，其余为去离子水。 Preferably, a formaldehyde-free linen fabric anti-wrinkle finishing solution, the composition of the anti-wrinkle finishing solution is as follows: every 1L of anti-wrinkle finishing solution contains 35g of silk fibroin finishing solution, 20g of sulfocarboxylic acid type water-soluble polyurethane, and 2.5g of hydroxyethyl acrylate , and the rest is deionized water.
本发明的一种无甲醛的亚麻织物抗皱整理液的制备方法包括如下步骤： The preparation method of a kind of formaldehyde-free linen anti-wrinkle finishing liquid of the present invention comprises the steps:
(1)将蚕丝浸轧在2g/L的碳酸钠溶液中进行脱胶处理，然后冷水洗涤后烘干； (1) silk padding is carried out degumming treatment in the sodium carbonate solution of 2g/L, then dry after cold water washing;
(2)将氯化钙溶液、去离子水和无水乙醇以1:7:2的比例配制成混合溶液，将经步骤1处理脱胶后的蚕丝浸泡在混合溶液中，70℃下放置3h； (2) Calcium chloride solution, deionized water and absolute ethanol are formulated into a mixed solution at a ratio of 1:7:2, and the silk degummed after step 1 is soaked in the mixed solution, and placed at 70° C. for 3 hours;
(3)将步骤2得到的物质转移到纳滤膜中，经去离子水透析，去除Ca2+、Cl-离子，再经活性炭吸附、过滤，得到丝素整理液； (3) Transfer the substance obtained in step 2 to a nanofiltration membrane, dialyze through deionized water to remove Ca 2+ , Cl − ions, and then adsorb and filter through activated carbon to obtain silk fibroin finishing solution;
(4)将步骤3得到的丝素整理液与磺羧酸型水溶性聚氨酯、丙烯酸羟乙酯以及去离子水混合，超声搅拌90min，得到无甲醛的亚麻织物抗皱整理液。 (4) Mix the silk fibroin finishing solution obtained in step 3 with sulfocarboxylic acid-type water-soluble polyurethane, hydroxyethyl acrylate and deionized water, and ultrasonically stir for 90 minutes to obtain a formaldehyde-free linen fabric anti-wrinkle finishing solution.
本发明具有以下技术效果： The present invention has the following technical effects:
本发明中的丝素整理液是一种生物环保的抗皱整理液，安全、无毒并且具有良好的生物相容性。但丝素分子结构中缺乏能与亚麻纤维发生共价交联的基团，因此若单独应用于亚麻织物的抗皱处理中效果不佳。为了解决这一问题，在本发明的抗皱整理液中引入了磺羧酸型水溶性聚氨酯，该物质在高温作用下发生解封反应，得到端基为-NCO的预聚体，在亚麻纤维上形成具有交联网状结构的薄膜；另一方面，-NCO具有很高的反应活性，可以与亚麻纤维上的羟基、丝素整理剂上的氨基等基团发生反应，提高整理剂与亚麻纤维的结合力。本发明中还加入了丙烯酸羟乙酯作为交联剂，可以在线型分子间起架桥作用，从而使亚麻纤维、丝素整理剂和聚氨酯中的相关基团相互键合交联成网状结构的物质，进一步强化了整理液与亚麻纤维间的交联作用。 The silk fibroin finishing solution in the present invention is a bio-environmental anti-wrinkle finishing solution, which is safe, non-toxic and has good biocompatibility. However, the molecular structure of silk fibroin lacks groups that can covalently cross-link with flax fibers, so if it is used alone in the anti-wrinkle treatment of flax fabrics, the effect is not good. In order to solve this problem, a sulfocarboxylic acid type water-soluble polyurethane is introduced into the anti-wrinkle finishing solution of the present invention, and the substance undergoes a deblocking reaction under the action of high temperature to obtain a prepolymer whose end group is -NCO. Form a film with a cross-linked network structure; on the other hand, -NCO has high reactivity and can react with hydroxyl groups on flax fibers and amino groups on silk fibroin finishing agents to improve the interaction between the finishing agent and flax fibers. Binding force. In the present invention, hydroxyethyl acrylate is also added as a cross-linking agent, which can act as a bridge between linear molecules, so that the related groups in flax fiber, silk fibroin finishing agent and polyurethane are bonded and cross-linked to form a network structure The substance further strengthens the cross-linking effect between the finishing liquid and the flax fiber.
经本发明中的抗皱整理液处理的织物防缩抗皱性能佳、强力损伤小，满足抗皱整理液的使用需求；此外，本发明的抗皱整理液在使用和存放过程中完全不会释放甲醛，安全无毒环保，在一些对衣物安全性要求极高的领域，尤其是婴幼儿服装领域具有极高的推广价值。 The fabric treated with the anti-wrinkle finishing solution of the present invention has good anti-shrinkage and anti-wrinkle performance, less damage to the strength, and meets the use requirements of the anti-wrinkle finishing solution; in addition, the anti-wrinkle finishing solution of the present invention will not release formaldehyde at all during use and storage, and is safe. Non-toxic and environmentally friendly, it has a very high promotion value in some fields that require extremely high clothing safety, especially in the field of infant clothing.
