无纺布又称不织布，是由定向的或随机的纤维而构成，是新一代环保材料，具有防潮、透气、质轻、不助燃、容易分解、无毒无刺激性、色彩丰富、价格低廉、可循环再用等特点，因具有布的外观和某些性能而称其为布。
无纺布广泛的应用于高档的一次性吸收物品的表层材料等卫生领域或其他相关领域。但其功能的体现主要是用化学药剂，来获得诸如消毒，抗菌等功能，或者添加相关物理材料，获得某种单一功能；另外现有的无纺布具有良好的吸湿功能，但当其受到压力后，其吸收的水分等还会从吸收的一方渗透出来。
本发明的特点是不采用化学药剂或添加剂，用不同的物理材料糅合，从而获得一种多功能的无纺布。本发明无纺布具有良好吸湿功能、抗菌功能、反渗透功能、抗紫外线功能、远红外线发射功能，无化学药剂的刺激性，可应用于高档的卫生领域。
