防SARS医用防护过滤材料结构与性能

介绍了所研制的非织造滤料具有复杂通道和纤维随机分布形成优良的过滤结构，滤料中纤维直径直接影响微粒扩散和惯性作用。采用驻极电介质技术，可有效地捕获和吸附空气中粒子，有效防止感染SARS病毒。通过实验说明了超细合成纤维滤料具有极佳的过滤效率和低阻力，是生产防SARS医用防护口罩、防护服及正压过滤器的理想滤材。

Structure and Properties of Medial Filter Materials in Preventing SARS

Nonwovensfilter materials have complex passage and excellent filter structure because of fiber random arrangement. Fiber diameter in filter materials influence the diffusion of particle and its inertness directly. Particle in the air may be captured and absorbed using electric technology, so preventing the SARS virus effectively. Super fine fiber have excellent filter efficiency and low resistance, it is ideal filter materials in producing medical protective mask, protective clothes and positive pressure filter.
