- Protein-containing natural fibers are the main source of the protein solution. Due to the unique properties of natural fibers, it has played an important role in textile materials since ancient times and is still widely used in the modern textile industry as a high-quality textile material.

Therefore, some natural fibers such as wool, silk, cotton or marijuana are sometimes wasted during processing. Due to the excellent properties of the fiber itself, the development of a new method for reusing those fibers has great market prospects. At the same time, not only the textile industry, but many other industries also require this technology in new materials or functional designs or applications.

纳米多功能蛋白银结构的原位合成方法 技术领域
本发明涉及一种纳米多功能蛋白银结构的原位合成方法,所述结 构至少具有抗菌、 紫外线遮蔽和红外线辐射的特殊功能。 背景技术
纳米多功能蛋白银结构可以在许多材料的固体表面上合成,如塑 料、 纺织品、 织物、 过滤料等等。 依次在这些材料的固体表面上加入 蛋白溶液、含银离子的溶液和还原剂溶液。接着会发生一系列的化学 反应和物理作用。例如, 当含银离子的溶液与还原剂溶液在固体表面 上接触时, 就会形成金属银粒子的纳米结构。 当蛋白溶液与固体表面 上的银离子或金属银粒子接触时, 就生成银 -蛋白的纳米结构。 最后, 在这些材料的固体表面上形成特殊的纳米结构。这样, 这些材料就同 时具有了有抗菌、 紫外线遮蔽和红外线辐射的功能。
含蛋白的天然纤维(如羊毛、 蚕蚕丝、 头发等)是所述蛋白溶液 的主要来源。 由于天然纤维独有的特性, 其从古代起就在纺织材料中 扮演着很重要的作用, 至今仍然被广泛地应用于现代纺织工业, 作为 高质量的纺织材料。 然而, 因为某些纤维长度短, 加上纺纱阶段的限 制 /要求, 并非所有的纤维都能用于纺纱。 因此, 一些天然纤维如羊 毛、 蚕丝、 棉花或大麻等有时在处理过程中会被浪费掉。 由于纤维本 身具有优异的性能, 因此, 研发一种重新利用那些纤维的新方法具有 很大的市场前景。 同时, 不仅仅是纺织工业, 而且许多其它的工业也 在新材料或功能设计或应用中需要这种技术。
近来涌现出对光的生物作用的研究,业已成为光学研究领域的重 要子域。大量的证据表明低能量的红和近红外线对组织具有生物刺激
作用, 其通过热调节下丘脑功能影响生物体的代谢状态。 一直以来, 人们都知道银具有抗菌活性。 银在高温下稳定, 不易挥发, 可以长时 间的用作杀菌剂,正因为银具有的这种新奇性,受到人们更多的关注。 最近对银纳米粒子进行了广泛的研究,。 许多研究者已经指出, 涂在 固体材料表面的纳米银材料具有额外的抗菌效果,但现今我们还不能 找到关于纳米银材料能够影响涂层的固体表面的红外线辐射特性的 报道。
基于对美国专利数据库的检索, 在许多的现有技术中, 都能用不 同的功能剂和 /或方法改善织物的功能特性。 例如, 增强纤维的紫外 线遮蔽性(如美国专利 US6607994、 US6565924和 US 6037280); 抗菌 性(如美国专利 US6596657和 US6541138 ); 湿度管理性能的增强(美 国专利 US6509285、 US6432504、 US6427493、 US6341505、 US6277469、 US5315717, US5735145, US4411660和 US 0064639A1 )。在申请号为 09/759241、 题为 "复合纺织材料 ( Composite Textile Material ) " 的 美国专利申请中, 发明人也发明了一种具有特别设计结构的纺织面 料,其中该织物结构的两个表面上的疏水或亲水 、面分布状态不同。
一些现有发明技术中, 发明人试着再次利用所述的短纤维, 例如 US6437050B1公开了一种聚合物纳米粒子组合物的制备方法,该组合 物是通过分散聚合的方法 (一种把聚合物物质转换成细粉末的方法) 制成, 其平均直径小于 100纳米。 CN94115873.X公开了一种由棉花或 大麻纤维制备平均尺寸为 2.5-lOnm的纳米级多细胞粉末的制备方法, 该方法采用了化学处理以及低温干燥、 粉碎和筛选步骤。 US5853764 公开了一种用碱性水溶液制备超细蚕丝粉的方法, 这是一种化学方 法。 US5718954要求保护一种超细粉末的制备方法, 其中的粒子的大 小在 ΙΟμηι级别上。 US5763538和 US5276138也公开了一种通过增溶作 用来处理动物毛发 /蛋白质的方法。 但是基于从专利数据库得到的检 索报告,还没有将纳米蛋白功能溶液原位应用于固体表面上以形成具
有其它性能的纳米结构。 发明内容
本发明的目的在于提供一种原位方法, 从环境保护、功能性增强 和那些短的 /使用过的蛋白材料的再次利用的角度, 用特别制备的功 能纳米角蛋白和银制剂处理固体表面, 从而为其提供其它的性能。
为实现上述目的, 本发明的方法包括:
1.纳米角蛋白 -银功能溶液的制备方法;
2.还原剂的制备;
3.用制备好的功能溶液通过传统的织物表面修整方法处理织物, 例如按既定的顺序进行的浸渍、 浸轧、 移印或喷雾、 涂覆方法。 附图说明

1.功能溶液的制备
- 参考在先的申请日为 2004 年 5 月 7 日、 申请号为 200410045621.8的待批中国专利申请 "纳米羊毛乳液和粉末、及其制
备方法以及用途"中的技术,其提出了如何制备功能纳米角蛋白材料, 纳米级角蛋白材料可以制成粉末或溶液的形式。
或者是按以下描述的另一方法来制备纳米角蛋白溶液。
- 在 300ml的圆颈烧瓶中, 把清洗过的羊毛 (10g) 与 7M尿素 ( 180ml), SDS十二垸基硫酸钠 (Sodium dodecyl sulfate, SDS)
(6g)和 2-巯基乙醇 (15ml)混合, 并在 50°C下摇动 12小时。 因为 角蛋白在 pH<5的酸性条件不会被萃取, 在 pH>9的碱性条件下会分 解, 在处理过程中, 水相在中性的 pH值范围内得到保持。 把得到的 混合物用不锈钢网过滤。 接着, 用含有 0.08 (重量百分比) Y0 2-巯 基乙醇的脱气水(3.5L, 二到三次)透析滤液, 得到还原的角蛋白的 无色透明溶液。
此外:
- 制备浓度为 0.1%-5%的角蛋白, 较佳的是 1%的角蛋白; - 把硝酸银(AgN03)溶解于去离子水中,得到浓度为 0.1%-10% (重量) 的硝酸银溶液, 较佳的是 4% (重量) 的硝酸银溶液;
- 把次磷酸钠 (NaH2P02 ) 溶解于去离子水中, 得到浓度为
0.1%- 10% (重量) 的次磷酸钠溶液, 较佳的是 4% (重量) 的次磷酸 钠溶液。
2.处理的顺序可以是下面三种顺序中的一种
使用已有的技术和顺序, 通过浸渍、 浸轧、 移印或喷雾的方式, 制备的溶液可广泛地用来调整固体材料的表面特性。
( 1 )按以下顺序处理材料: 角蛋白溶液- > AgN03 -> NaH2P02 -> 清洗并干燥。 以处理纺织品为例, 具体为:
用浸渍、 浸轧、 移印或喷雾的方式把角蛋白溶液置于纺织品上。 接着, 用浸渍、 浸轧、 移印或喷雾的方式把 AgNO^ 液置于纺织品 上。 接下来, 用浸渍、 浸轧、 移印或喷雾的方式把 NaH2P02溶液置
于纺织品上。把反应系统的 PH值调到 2-6, 较佳的是调到 4。反应温 度设在 40-60 °C, 较佳的是 50°C。 反应湿度设为 80%-100%。 反应时 间大约为 10-30分钟,较佳的是 20分钟。再把得到的纤维的 PH值合 适地调整到中性 PH范围。 然后在 100-120°C下把纺织品固化 2-10分 钟。 用干净的水清洗纺织品, 最后进行干燥。
( 2 )按照以下顺序处理材料: AgN03 ->角蛋白溶液- > NaH2P02 -> 清洗并干燥。 以处理纺织品为例, 具体为:
用浸渍、浸轧、移印或喷雾的方式把 AgN03溶液置于纺织品上。 接着,用浸渍、浸轧、移印或喷雾的方式把角蛋白溶液置于纺织品上。 接下来, 用浸渍、 浸轧、 移印或喷雾的方式把 NaH2P02溶液置于纺 织品上。把反应系统的 PH值调到 2-6, 较佳的是调到 4。反应温度设 在 40-60°C, 较佳的是 50°C。 反应湿度设为 80%-100%。 反应时间大 约为 2-30分钟, 较佳的是 20分钟。 再把得到的纤维的 PH值合适地 调整到中性 PH范围。然后在 100-120°C下,把纺织品固化 5-10分钟。 用干净的水清洗纺织品, 再进行干燥。
(3 ) 按照以下顺序处理材料: AgN03 -> Na¾P02 ->角蛋白溶液 ->清洗并干燥。 以处理纺织品为例, 具体为:
用浸渍、浸轧、移印或喷雾的方式把 AgN03溶液置于纺织品上。 接着, 用浸渍、 浸轧、 移印或喷雾的方式把 NaH2P02溶液置于纺织 品上。 接下来, 用浸渍、 浸轧、 移印或喷雾的方式把角蛋白溶液置于 纺织品上。把反应系统的 PH值调到 2-6, 较佳的是调到 4。反应温度 设在 40-60°C, 较佳的是 50°C。 反应湿度设为 80%-100%。 反应时间 大约为 10-30分钟。 再把得到的纤维的 PH值合适地调整到中性 PH 范围。 然后在 100-120°C下, 把纺织品固化 5-10分钟。 用干净的水清 洗纺织品, 再进行干燥。
作为例证, 根据以下的步骤采用特殊的技术处理纯棉纺织纤维:
- 由羊毛纤维制备角蛋白溶液;
- 制备 4%的 AgN03溶液;
- 制备 4%的 NaH2P02溶液;
- 把纯棉纺织纤维浸在制备的 AgNO^ 液中;
- 把处理过的棉纤维浸在制备的 NaH2PO^§液中;
- 把处理过的棉纤维浸在制备的角蛋白溶液中;
-将反应系统的 PH值调整到 3。 反应温度设定为 50°C。 反应湿 度设为 100%。 反应时间为 20分钟。 接着把得到的纤维的 PH值合适 地调整到中性 PH范围。然后在 100 °C下把织物固化 10分钟。用干净 的水清洗织物, 再进行干燥。
为表征处理的织物的特性, 进行了以下实验:
涂层的结构和形态用 JSM 6335F 场发射扫描电子显微镜在 3.0KV的电压下进行检测。 涂层的结晶度用 X射线衍射光谱来检测 (Philips Expert System XRD ) 参见图 1和图 2 ,得到的 SEM图片清 楚地表明纤维表面上有许多的纳米级粒子, 其尺寸小于 100nm。
XRD
对处理过的和未处理的样品进行 XRD分析, 结果显示与未处理 的样品比较, 用给定的处理技术处理后的纳米角蛋白-银组合物的结 晶度较低。
FTIR
参见图 4的 FTIR结果, 出现了多个吸收峰, 1653cm— 1吸收峰表 明多肽键合的 C=0键在伸缩波动; 1548cm- 1吸收峰表明肽链的反式 结构; 以及 1401cm— 1吸收峰表明肽链的顺式结构。
抗菌性
使用标准 AATCC147来评价处理的织物的抗菌效果。 与未处理 的对照物相比, 处理过的织物对 E.Coli (大肠埃希氏菌) 和 S.aureus
(金黄色葡萄球菌)有很好的抑制效果, 在处理过的样品周围分别具 有干净抗菌区。相关的测试结果示于表 1中, 而抗菌效果则分别示于
图 5和图 6中。
表 1 : 通过纸片扩散法 (定性分析) 进行抗菌测 1试的结果
E.coli (ATCC 25922) S.aureus(ATCC 25923) 样品 S (7mm) S ( 8.5mm) 对照品 R R
注释: S- 敏感的 (含有抗菌环) -表明有杀菌活性
R- 耐受的 (无抗菌环) -表明无杀菌活性
紫外线遮蔽
采用标准 AS/NZS 4399: 1996对织物的紫外线遮蔽效果进行了 测试, 其结果示于图 7中。 参考图 7, 可以看到, 未处理的对照样品 的 UPF值仅仅在 10左右,而处理过的样品则近乎为 1000。需要指出 的是, 几乎所有的紫外线都能被遮蔽, 具有极佳的保护性能。
红外辐射的增强
根据发明人的另一待批中国专利申请中的技术(用于测量织物的红外 辐射属性的装置和方法, 其申请日为 2004年 9月 7日, 申请号为: 200410068752.8 ), 对处理过的和未处理的织物表面的红外辐射特性 进行了评价, 红外线辐射强度分别示于图 8和图 9中。与对照样品的 测试结果比较,处理过的织物的两个表面所辐射的红外线强度有显着 的增加。 特别地, 透射面 (transmission surface ) 上的红外线强度大 于 1。 这表示在透射面上的红外辐射强度几乎与没有织物阻挡一样, 这显示经过本整理后,织物或降低了阻挡红外透射的能力或将部分其 它的能量转换成红外在透射面发射出来。透射而在穿着时是紧靠皮肤 的, 红外发射能力的增强使皮肤感到温暧。
