摘要: 测试了不同锗元素含量面料的释放负离子、远红外及抗菌性能,研究了不同锗元素含量面料与其功能性性能关系。结果表明,含锗面料具有释放负离子、远红外及抗菌性能,性能指标符合国家标准要求。负离子性能上,随着锗元素含量的增加,含锗面料的负离子发生量依旧维持在中等水平;远红外性能上,随着锗元素含量的增加,含锗面料的远红外发射率略有增加,增幅不显著,温升基本维持在1.5℃;抗菌性能上,即使锗元素含量低至0.53mg/kg时,其大肠杆菌和金黄色葡萄球菌的抑菌率基本在99%及以上,白色念珠菌的抑菌率随着锗元素含量的增加从85%增至96%。

Abstract: Negative ions, far-infrared and antibacterial properties of germanium fabric were tested and the relationship between the content of germanium and its functional properties was studied. The result shows the germanium-containing fabric has the characteristics of releasing negative ion, far-infrared and antibacterial property and the property indexes meet the requirements of national standards. About the negative ion property, the negative ion content of germanium-containing fabric is maintained at the medium level with the increase of Ge content. For the far infrared property, the infrared emission emissivity of the germanium-containing fabric can be improved slightly with the increase of Ge content, and the temperature rise is maintained at 1.5℃ . with regard to the antibacterial property, the inhibitory rates of Escherichia coli and Staphylococcus aureus are 99% and above even when the Ge content is as low as 0.53 mg/kg and the inhibitory rate of Candida albicans increases from 85% to 96% with the increase of Ge content.

鍺,符号Ge,位于元素周期表第32位,是碳族元素中的一员,被广泛用于电子、航空、医疗等行业[1]。已有研究证明,锗元素具有抗病毒、抗氧化,产生负离子,促进血液循环,改善身体体质等功效[2-3]。为了开发满足市场需求的新产品,众多厂家对锗元素产品进行了研发。如日本清川株式会社在制丝阶段把0.4μm的天然锗矿石研磨成纳米级粉体后,结合无机载体制作成母粒得到锗纤维长丝[4];国内也有研究人员采用有机锗整理的方法使织物富有保健性[5]。在市场上锗纤维产品众多,大多为文胸、内衣裤、护膝、腰带等产品,产品宣传上大多为锗纤维面料可以促进血液循环、改善新陈代谢、释放负离子、抗菌抑菌,以及远红外等功能。……
