近年来，由于人们对改善卫生和欧洲杯足球竞彩人身保护的潜力以及减少现代社会中疾病传播的潜力，抗菌材料引起了人们的兴趣。聚合物技术领导者上升性能材料欧洲杯足球竞彩已经引入了其开创性聚合物的抗菌技术Acteev Protect™，该技术使用活性锌离子防止服装，防护设备和过滤器件中的真菌和微生物生长。2020欧洲杯下注官网
The vast majority of modern consumer fabric products contain natural or synthetic fiber blends, such as cotton, wool, polyester, nylon, or elastane, which are naturally susceptible to bacterial and fungal growth.
Clothing, upholstery, and textiles affected by microorganisms can deteriorate and discolor, or develop a bad smell. This limits the product’s durability, aesthetics, and lifetime value. Washing alone is not always effective at eliminating the microorganisms and removing odor build-up.
更重要的是，抗菌特性非常需要保护性服装，面罩，空气过滤设备和其他用于抵抗医疗保健和制药行业中致病生物的产品。2020欧洲杯下注官网
结果，制造商现在专注于开发具有内置抗菌保护的面料产品。
Metal-Based Antimicrobial Agents Suitable for Industrial Processing
即使在非常低的浓度下，铜，银和锌等金属也可能对微生物具有极高的毒性。由于其杀菌活性，金属被用作与医疗保健，农业和制药行业有关的多种应用中的抗菌剂。
与其他抗微生物剂不同，金属在各种环境和加工条件下都是稳定的，使其适合在大多数工业制造工艺中使用。
通常将基于抗菌金属的剂作为固体颗粒形状的添加剂或涂料应用于不同载体中的吸收金属离子（例如盐）。欧洲杯猜球平台
高级聚合物技术用于抗菌保护
由Ascend Performance材料开发的创新ACTEEV Protect™聚合物抗微生物技术依赖于一种新型方法，该方法可以通过将锌离子直接掺入聚合物矩阵中，从而在聚合过程中创建聚合物/金属纳米复合材欧洲杯足球竞彩料。
上升性能材料欧洲杯足球竞彩is a global supplier of high-quality plastics, fibers, and specialty chemicals for a wide range of consumer and industrial applications, including textile and packaging products, components for the automotive, electrical and electronics industries, and chemical compounds for the agrochemical and petrochemical industries.
Central to Ascend's product portfolio is a wide range of polyamide 66 (also known as Nylon 66) resins, fibers and fabrics. With five fully integrated manufacturing facilities in the USA and 2,500 employed staff globally, the company is the world's largest integrated producer of polyamide 66 products.
Calling on the company's proprietary polymer technologies and expertise in the production of polyamide 66, Ascend's team of scientists and engineers started the development of the Acteev Protect™ technology in 2016, by combining the antimicrobial properties of active zinc ions with the softness, versatility, and durability of Ascend's polyamide fabrics and fibers. This helped to deliver unparalleled performance and antimicrobial efficacy.

Zinc Ions Can Stop Bacterial and Fungal Growth and Deactivate Viruses
Previous research has shown that divalent zinc ions can disrupt bacterial metabolic pathways and can cause damage to the bacterial membrane, hindering bacterial growth.
A research team at Leiden University in the Netherlands has recently established that divalent zinc ions can also inhibit the replication of several types of viruses, including SARS-coronavirus (SARS-CoV).

具有无与伦比的抗菌特性的多功能和耐用织物
Ascend’s senior vice president of technology, Dr. Vikram Gopal, explains that by embedding active zinc ions into the polymer matrix, his R&D team was able to create polymer-based antimicrobial material with long-lasting microbial inhibition that does not wash away, unlike other silver-based antimicrobial agents. Silver is typically used as a topical finish or a coating applied to the final product, which is a water-intensive process where the excess silver is washed off and eventually disposed into the aquatic environment.
Due to the hydrophilic properties of the polyamide fibers, they can retain some moisture in their microenvironment, allowing embedded zinc ions to be activated and diffuse out of the polymer matrix to attack any bacterial or fungal growth in the fabric.
同时，用ACTEEV Protect™制成的服装，运动服和保护服装在50次或更多的洗涤后保留其抗菌特性，同时在整个服装的一生中保持无味和舒适。
Acteev Protect™ antimicrobial materials feature all the benefits of premium polyamide 66 fabrics, which are softer and offer more comfort than other types of nylon or polypropylene fabrics. Polyamide textile products better resist abrasion, do not shed microfibers, and can be dyed or printed on in bright colors.
除了适合服装和内饰应用的机织和编织Acteev Protect™织物外，Ascend Performance材料还提供各种纳米和微纤维非织造（熔体吹制）织物，纤维直径为0.4-0.6微米和2-8微米欧洲杯足球竞彩， 分别。这些织物适用于内置抗菌保护的空气过滤应用。与传统的聚丙烯融化非织造材料相比，它们提供的过滤效率更好，压降低。欧洲杯足球竞彩

Responding to a Global Crisis
15多个专利系列涵盖的Ascend基于聚合物的抗微生物技术的独特功能使其特别适合单使用和可重复使用的面罩，过滤器和保护服装，如果暴露于水或酒精中，则保留其功效。
为了满足全球对抗菌保护的高效和耐用个人防护设备的需求，与独立的测试实验室合作以获得其产品的认证。2020欧洲杯下注官网欧洲杯足球竞彩同时，该公司优化了供应链和重新分配的资源，以扩大ACTEEV保护生产。
根据Gopal博士的说法，严格的独立测试方案符合ISO和ASTM标准，表明ACTEEV™技术停用了SARS-COV-2，导致COVID-19疾病的冠状病毒和其他病原体，包括H1N1，Betacoronavirus OC43，Human Coronavirus 229e，。它还抑制了一系列革兰氏阳性和革兰氏阴性细菌的生长，例如金黄色葡萄球菌，克雷伯氏菌肺炎和大肠杆菌的生长。
基于聚合物的医疗应用抗菌技术
The test results allowed上升性能材料欧洲杯足球竞彩to submit a premarket notification to the US Food and Drug Administration (FDA) for clearance to market the Acteev™ antimicrobial technology in the United States in a medical device - a surgical mask branded Acteev Biodefend™.
除了开发用于医疗应用的聚酰胺66织物外，该公司还打算通过引入工程化的塑料来扩展其抗菌聚合物技术，用于具有抗菌保护的高接触表面和生物医学产品。
DISCLAIMER: Acteev™ technology has been shown in laboratory tests to destroy SARS-CoV-2, the coronavirus that causes COVID-19, and other pathogens, including H1N1, coronavirus 229E and Gram-positive and Gram-negative bacteria such as staphylococcus and E. coli.
