真丝织物的汽蒸法纳米银抗菌整理 总被引:2,自引:0,他引:2
为了实现真丝织物的抗菌性能,以一种含有多胺基化合物(RSD)和硝酸银的混合整理液对真丝织物进行处理,并采用汽蒸法在位还原得到纳米银抗菌真丝织物.对纳米银抗菌真丝织物表面纳米银的形成、纳米银的形态、纳米银的含量、纳米银抗菌真丝织物的白度、抗菌性能和耐久性能等进行了测试与分析.结果表明,当纳米银含量为81.65 mg/kg时,对金黄色葡萄球菌和大肠杆菌的抗菌率分别达99.49%和99.98%,洗涤50次后,对金黄色葡萄球菌和大肠杆菌的抗菌率仍保持在97.43%以上;纳米银抗菌真丝织物的白度影响较小. 相似文献

以商用氯菊酯除螨剂为保护剂,硼氢化钠为还原剂,常温下还原硝酸银制备得到纳米银溶液。最优的纳米银制备工艺为:纳米银溶液质量浓度800 mg/L,保护剂质量浓度36 g/L,反应温度30℃。所制备的纳米银为球形,平均粒径约为27 nm。将制得的纳米银溶液利用浸轧烘工艺对真丝织物进行抗菌处理。整理后的真丝织物负载量为1 356 mg/kg时,对大肠埃希菌和金黄葡萄球菌的抑菌圈分别达到10.6 mm和10.4 mm,抑菌率均达到99.99%,显示出优异的抑菌性能。扫描电镜观察发现纳米银均匀分布在蚕丝纤维表面,无团聚现象。 相似文献

为了制备抗菌桑蚕丝制品,利用端氨基超支化合物季铵盐(HBP-HTC)对桑蚕丝织物进行抗菌整理,研究HBP-HTC水溶液及其整理后的桑蚕丝织物的抗菌性能。牛津杯扩散法实验表明,HBP-HTC水溶液对金黄色葡萄球菌和大肠杆菌具有良好的抗菌性能,随着HBP-HTC接枝的季铵基团数量的增加以及浓度的提高,其抗菌性增加。抗菌动力学亦表明,HBP-HTC具有优异的抗菌性能,当质量浓度为20mg/L时即表现出良好的抗菌性。当HBP-HTC质量浓度为5g /L时,经HBP-HTC整理后的桑蚕丝织物抑菌率达99%以上,HBP-HTC整理的抗菌桑蚕丝织物具有良好的耐洗牢度,且染色加工对其抗菌性能影响很小。 相似文献

In this paper, silk fabrics were modified with flame retardant dimethyl-2-(methacryloyloxyethyl) phosphate using radiation of UV light with band 254?nm initiated by a photo catalyst methyl 2-benzoylbenzoate. Attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), energy dispersive X-ray spectroscopy, and scanning electron microscope (SEM) analysis were used to investigate the surface grafting evidence of flame retardant. Wide angle X-ray diffraction analysis showed the crystalline structure of grafted silk fiber and showed that graft treatment did not change the crystalline structure of silk fiber. Thermal gravimetric analysis explored the thermal decomposition mode of control and grafted silk fibers. The initial decomposition temperature decreased and produced more residues during main decomposition stage. SEM analysis of char residue showed that the grafted silk will produce solid and rigid char after combustion. Heat release rate and CO yield of modified silk fabrics both decreased. From above, it can get the flame retardancy mechanism that treated silk fiber promoted to form more nonflammable char during combustion so as to improve fire safety in real fire. 相似文献

People’s inclination toward medical textiles for healthy life style has created a rapidly increasing market for antimicrobial textiles, which, in turn, has stimulated intensive research and development. The aim of our study was to prepare cellulose fabrics finished by allicin-conjugated nanocellulose, whose properties were investigated by scanning electron microscopy, X-ray diffraction, and Fourier transforms infrared spectroscopy. The antibacterial ability of the treated fabrics was determined by AATCC test method 100–1993. The durability of antimicrobial activity to washing process was also evaluated. The results showed significant antibacterial activity against Staphylococcus aurous, statistically different from negative control fabric (finished by nanocellulose without allicin) (p < 0.05). The antibacterial activity after two home laundering cycles of all finished fabrics was only slightly reduced. It can be concluded that allicin-conjugated nanocellulose can be attached to cellulose textiles by a simple conjugation method to create durable antibacterial properties. 相似文献

为获得耐水洗和高导电的纺织材料,采用原位还原法将氧化石墨烯(GO)用于蚕丝织物的导电整理。探究了GO 质量浓度、GO 溶液pH 值、还原剂用量、超声时间和十二烷基苯磺酸钠质量浓度等对蚕丝织物导电性能的影响,分析了还原氧化石墨烯(rGO)导电蚕丝织物的导电耐久性,并借助扫描电子显微镜对织物形貌进行表征。结果表明:在GO 质量浓度为15 g/ L,GO 溶液pH 值为5,还原剂质量浓度为5 g/ L,超声时间为30 ~ 60 min 时,采用原位还原法还原吸附GO 并烘干的蚕丝,其表面电阻值降低至1. 372 kΩ/ cm,导电性优良;蚕丝表面被GO 完全覆盖,经20 次水洗或机械摩擦后蚕丝织物依然保持较好的导电性能。 相似文献
