双组份熔喷纤维可以补充单一聚合物性能的不足，如聚丙烯比较便宜，但如用于医卫材料，它却不耐射线照射，这样可以聚丙烯为芯，在其外层选择适当的耐辐射聚合物包裹在外面就可以解决耐辐射的问题。从而可以使产品价格便宜，又能完成功能要求，如在医疗领域可用于呼吸系统的热和湿的交换器，可提供合适的类似天然的热和湿度。它具有质轻、用可弃或便于消毒、价格便宜，还可起到除去污染物过滤器的附加作用。它可由两种均匀混合的双组份熔喷纤维网组成。采用皮芯型双组份纤维，芯子为聚丙烯，皮层为尼龙。双组份纤维亦可采用异形截面，如三叶形、多叶形，使其表面积更大，同时还可以在其表层或叶尖部分采用能提高过滤性能的聚合物。烯烃类或聚酯类熔喷法双组份纤维网可以做成柱形液体和气体过滤器。熔喷双组份纤维网还可用于香烟过滤咀；利用芯吸效应做高档吸墨水芯子；保液和输液的芯吸棒等。
Two-component melt-blown fibers can supplement the shortcomings of single polymer performance, such as polypropylene is cheaper, but it is not resistant to radiation when used in medical and health materials, so that polypropylene can be used as core, and the problem of radiation resistance can be solved by choosing appropriate radiation-resistant polymer wrapped in its outer layer. Thus, the product can be cheaper and meet the functional requirements. For example, in the medical field, the heat and humidity exchanger which can be used in the respiratory system can provide suitable natural heat and humidity. It is light in weight, disposable or easy to disinfect, cheap in price, and can also play an additional role in removing pollutant filters. It can be made up of two uniformly mixed two-component melt-blown fibre nets. The core is polypropylene and the skin is nylon. Two-component fibers can also adopt special cross-section, such as trefoil and polyfoil, to make their surface area larger, and can also use polymer which can improve the filtration performance on the surface or tip of the blade. Olefin or polyester melt blown two-component fiber mesh can be made into cylindrical liquid and gas filters. Melt-blown two-component fiber mesh can also be used for cigarette filter tip, high-grade ink wick made by wicking effect, wicking wick wick for liquid retention and infusion, etc.
