The fifth plan was desirable one for the development of medical barrier fabrics with fine comprehensive properties. In this plan, one-layered texture with differential face, which made fibers disposed in three layers, was selected as texture of upper and inferior layers, therefore the difficulties of weaving were reduced. Moreover, because superfine fibers with better performance and higher price were disposed only in liquid-repellent layer and ordinary polyester filaments with smaller fineness and lower price were disposed in inferior layers, the thickness and cost were reduced based on fine liquidrepellency.

通过对比分析得出，第五方案是在开发具有优良综合性能的医用屏蔽织物时最可取的一种设计方案，它的上、下层均采用了单层的异面组织，在高密下使纤维在织物呈三层配置，大大地降低了织造的难度，并且此方案仅在拒液层的经、纬向配置了性能较好、价格较贵的超细涤纶长丝，而在织物的下层配置了纱支较细、价格较低的普通涤纶长丝，这样就在保证织物具有优良的拒液性能的基础上降低了织物的厚度和成本。
