The polyester fibre of resisting bacterium is one without which people can t live in modern times , but how to restrain the bacterium propagating excessively and keep people in health is a most important goal that fabrics and clothing industry are striving for . fibre of resisting bacterium can kill the bacterium effectively with the ratio of more than 99 % and it can restrain microbes . the polyester fibre of resisting ultraviolet radiation is also widely used . with the decreasing of ozonospheres in the atmosphere , there are more ultraviolet radiation in the sunlight which do harm to our skin , especially for those men working outdoors , it is more important to think about the way to lessen the harm . the polyester of burning - resisting has attracted more attention at home and abroad and burning - resisting textiles has been advanced definitely by law in many countries . our nation has also made strict claims in some special areas , such as fabrics in vehiciles and vessels , decorative fabrics in hotels . the everlasting burning - resisting fibres and textiles are badly needed . infrared ray fibre is also a new functional one that can absorb and reflect infrared ray after being processed physically . it s functions include physical therapy wet - ejecting and bacterium - restraining . this warm - preserving material can absorb the emitting heat from our bodies , at the same time it can also absorb and reflect the needed 4 - 14 urn wavelength ultraviolet radiation and accelerate netaboiism . fibre of resisting infrared ray is important in military areas 抗菌纤维具有永久的抗菌性，对金黄色葡萄球菌、大肠杆菌杀菌率大于99 ，能有效抑制细菌繁殖，起到抗菌防臭作用；抗紫外线聚酯纤维的用途也是异常广泛的，随着大气层中臭氧层的日渐稀薄，日光中的紫外线日益增加，对人体皮肤形成极大危害，尤其对于长期从事野外工作的人，因此设法减少紫外线对人体的伤害显得尤为重要；阻燃聚酯纤维则是一种倍受国内外人士密切关注的纤维，纺织品阻燃在许多国家已有明确法令规定，我国也逐渐在某些特殊使用范围做严格要求，如车船内用纺织品，高级宾馆的内装饰织物等，而且具持久性阻燃性的纤维和织物是现在更为需要的，真可谓用途非常广泛；远红外纤维也是一种经过物理改性后具有吸收并反射远红外线的新型功能性纤维，是一种具有优良理疗功能、热效应功能和排湿透气抑菌功能的新型纺织材料及保温材料，能吸收人体自身向外散发的热量，吸收并反射回人体最需要的4 14 m波长的远红外线，促进人体的新陈代谢；抗红外线纤维，则在军事上有着重要的作用。
