Description
技术领域technical field
本发明涉及织物领域,具体涉及一种包含银改性纳米碳纤维的防水防油织物及其制备方法。The invention relates to the field of fabrics, in particular to a water- and oil-repellent fabric comprising silver-modified carbon nanofibers and a preparation method thereof.
背景技术Background technique
随着生活水平的提高,人们对纺织品、服装提出了各种功能性的要求,对于衣物的防水性、防油性和抗菌性要求越来越高。通常的做法是将织物整理剂采用浸轧、浸渍、喷涂等方式形成于衣物表面,起到防水、防油和/或抗菌的目的。一方面,以防水为例,通常采用涂层使得织物表面的间隙被封闭或减小,从而具有防水性,但是会影响织物的透气性和舒适性;另一方面,现有技术并未过多关注处理后的织物,其防水性、防油性和抗菌性的持久能力。With the improvement of living standards, people have put forward various functional requirements for textiles and clothing, and the requirements for the waterproofness, oil resistance and antibacterial properties of clothing are getting higher and higher. The usual practice is to form the fabric finishing agent on the surface of the clothing by padding, dipping, spraying, etc., for the purpose of waterproofing, oil-proofing and/or antibacterial. On the one hand, taking waterproofing as an example, coatings are usually used to close or reduce the gaps on the surface of the fabric, so as to have waterproofness, but it will affect the breathability and comfort of the fabric; on the other hand, there are not too many existing technologies. Focus on the treated fabric's long-lasting ability to water, oil, and antimicrobial properties.
现有技术CN110924147A公开了一种织物的后处理方法,将织物的纤维浸没于织物整理剂中处理,干燥后纺织成织物;使织物具有芳香气味,容易被人接受,还含有杀螨剂达到抗菌除螨的作用。该申请的织物纤维的处理方法仅为在8-12℃浸泡0.5-1h,也未对抗菌能力和持久力进行测试。The prior art CN110924147A discloses a post-treatment method for fabrics. The fibers of the fabric are immersed in a fabric finishing agent for treatment, and then woven into fabrics after drying; the fabrics have a fragrant odor, which is easy to be accepted by people, and also contains acaricides to achieve antibacterial effects. The effect of removing mites. The treatment method of the fabric fiber of the application is only soaking at 8-12° C. for 0.5-1 h, and the antibacterial ability and stamina are not tested.
另外,处理剂是否使用方便,也是未考虑的问题。例如CN101161916A公开了一种纺织用纳米防护液,对织物进行表面处理,实现防水防油等功能;但是使用时需要先对织物进行洗净油污、灰尘等处理,然后将该纳米防护液喷涂在织物表面,再在80-100℃进行熨烫;织物脏了清洗之后,还需再次熨烫才能具被防护功能。In addition, whether the treatment agent is easy to use is also an unconsidered issue. For example, CN101161916A discloses a nano-protective liquid for textiles, which is used for surface treatment of fabrics to achieve functions such as waterproofing and oil-proofing; however, the fabric needs to be cleaned of oil stains, dust, etc. before use, and then the nano-protective liquid is sprayed on the fabric. The surface is ironed at 80-100°C; after the fabric is dirty and cleaned, it needs to be ironed again to have the protection function.
因此,需要一种使用方便及防水性、防油性和抗菌性能力持久的织物。Therefore, there is a need for a fabric that is easy to use and has long-lasting water, oil and antimicrobial properties.
