Description

含银纺织品的制备方法 发明领域
本发明涉及 H4Ag206溶液的用途， 具体地说， 涉及其在生产含银 抗菌纺织品中的应用。 本发明还涉及一种含银抗菌纺织品的简化的制 造方法。 背景技术
'具有抗菌性能的含银纺织品在现有技术中是一种公知的产品。在本 领域中， 有多种制备含银纺织品的方法， 但绝大多数是利用还原剂将 硝酸银还原成单质银， 然后再利用氧化剂将还原的单质银， 或进一步 氧化成氧化银。 例如， 蒋建华的中国专利 CN1034090C公开了一种长 效广谱抗菌织物的制造方法， 该方法包括将硝酸银溶于氨水中， 再加 入葡萄糖还原， 然后利用高温至织物出现褐黑色和黄褐色表面。 朱红 军等的国际申请 WO03/14627公开了一种防集聚纳米银抗菌纺织品及 其制备方法， 该方法是将硝酸银溶于氨水中得到 [Ag(NH3)2]+， 再用还 原剂将 [Ag(NH3)2]+还原成单质银固定在织物上， 然后用氧化剂进一步 将含银织物氧化以得到含银抗菌织物。
刘祥文的中国专利申请 CN1395828A公开了一种纳米银抗菌微粒 实地快速组装方法， 其是将硝酸银直接喷洒或涂刷于织物表面， 经还 原剂或光照处理得到抗菌含银织物。
美国专利 US6436420B1公开了一种制备含银织物的方法， 该方法 是将织物浸渍在含有溶解的硝酸银的水溶液中， 浸渍一段时间后， 取 出该织物， 并将其浸渍于热的含氢氧化钠和过硫酸钠的水溶液中， 再 将溶液加热到 95-100°C， 由此得到所需的含银织物。 该方法是通过两 次浸渍， 第一次浸渍是使一价银离子浸入织物的纤维之间或沉积中纤 维上， 第二次浸渍是通过将一价银离子氧化成过氧化银 (Ag404)， 以使 织物含有过氧化银而具有抗菌性。
已转让给本申请人的中国专利申请 CN1214867A公开了一种含银 杀菌剂的制备方法， 该方法包括以下步骤： 1 )取银的氧化物， 加入蒸 馏水； 2) 搅拌 15-60分钟后， 逐滴加入浓酸， 以使 pH值为 2-3.5; 3) 澄清至少 2小时， 倒出澄清液； 4) 向沉淀物中加入过氧化氢， 则得到 含 H4Ag206的杀菌剂。 该方法的特点是以银的氧化物， 例如氧化银或 过氧化银为原料， 而不是通常所使用的硝酸银， 这样就避免了将银离 子还原成单质银的步骤。 发明内容
本发明正是基于中国专利申请 CN1214867A所得的杀菌剂的用途。 本发明利用含 H4Ag206的杀菌剂制备含银的抗菌织物， 大大简化了工 艺流程， 从而节约了生产成本。 因此， 本¾明的一个目的是提供含 H4Ag206的杀菌剂的应用，更具体地说，本发明的目的是提供一种简化 的生产含银抗菌纺织品的方法。 本发明方法避免了高温氧化带来的一 系列的弊病， 大大节省了能源， 因此， 使生产成本降低。
因此，本发明提供了一种含银纺织品的制备方法，该方法包括以下 步骤：
1 ) 制备得到含 H4Ag206的溶液；
2) 用所得到的 H4Ag206溶液浸渍、 淋洗、 喷射或涂敷坊织品； 然 后
3 ) 干燥该湿纺织品。 具体实施方式
一方面，本发明涉及高价银离子溶液的应用。本发明的高价银离子 溶液是 H4Ag206溶液， 其中， 银离子是正四价氧化态。 该溶液的一种 制备方法已公开在中国专利申请 CN1214867A上。其是以银的氧化物， 例如氧化银或过氧化银作为原料， 在酸性介质中加入过氧化氢而得到 的， 所得溶液中银离子的总含量为 l-5000ppm。此外， 高价银离子溶液 还可以通过将氧化银溶解于过硫酸盐中而得到， 所得溶液中银离子的 总含量为 l-500ppm， 此方法公开在中国专利申请 CN1149389A中。 由 以上两种方法得到的高价银离子溶液都可以用于本发明中。
本发明涉及使用高价银溶液制备含银抗菌纺织品。本发明方法包括 以下步骤： 1 ) 制备得到含 H4Ag206的溶液；
2) 用所得到的 H4Ag206溶液浸渍、 淋洗、 喷射或涂敷纺织品； 和
3 ) 干燥该湿纺织品。
在本发明方法中，可以使用的紡织品包括天然纺织材料和合成纺织 材料。 可用于本发明的天然纺织材料可以是棉、 毛、 麻、 甲壳胺和丝， 优选为棉， 例如纱布、 纱线、 全棉无纺布等。 可用于本发明的合成纺 织材料是指合成纤维， 即一种人造纤维， 包括但并不局限于粘胶、 聚 酯、 尼龙、 人造丝以及醋酯纤维等， 可以单独使用其中的一种， 也可 以使用上述产品的混纺织品， 可以是织物形式， 也可以是纤维或纱线 形式。 本发明所用的纺织品可以是针织物、 机织物、 无纺织物或纱线。
在本发明方法中， 用 H4Ag206溶液浸渍、 淋洗、 喷射或涂敷纺织 品。 所用的方法是本领域常规的方法。 然后使润湿的纺织品干燥。 用 H4Ag206溶液浸渍、淋洗、喷射或涂敷纺织品的时间， 根据纺织品类型 的不同而不同。 例如， 如果是吸水性好的全棉纺织品， 其浸渍时间可 以很短， 仅 1 秒钟即可， 而对于粘胶等吸水性差的合成纤维， 浸渍时 间则要长些，可以是 30秒以上。干燥的方法可以采用本领域常的方法， 一般在 50-250°C下干燥， 也可以直接用日光照射或用紫外线辐照。
用本发明方法可以通过控制高价银离子溶液的银离子浓度来控制 纺织品的银含量。 由本发明方法所得纺织品的银含量可高达 120μ§/ πι2。 具体的银含量还取决于纺织品的类型， 例如取决于织物编 织的松紧度， 或是否是天然织物还是合成织物。 实施例
