摘　　要：为了改善海藻纤维敷料性能，降低新型敷料成本，以海藻酸钙纤维、聚乙烯醇纤维为原料，制备了一种层合结构的海藻酸钙纤维／聚乙烯醇纤维复合医用敷料，并研究了中间层面密度不同的敷料的吸湿性能、水蒸汽透过性能和舒适性能变化。结果表明：当中间层面密度在40～80g/m^2时，敷料每100cm^2吸收的液体质量均大于16g，并随中间层面密度增加而增大；敷料的水蒸汽透过性能则呈降低趋势，但水蒸汽透过率均在2．1kg·m^2／24h以上；敷料沿各层梳理方向的可伸展性和永久变形要大于垂直于各层梳理方向，敷料的可伸展性小于2．3N／cm，永久变形小于13％，因此具有良好的舒适性能。To improve the alginate fiber dressing performances and reduce the cost, a new calcium alginate fiber/PVA fiber composite dressings developed with calcium alginate fibers and polyvinyl alcohol fibers as material. The effect of the dressings of different intermediate layer weight on hygroscopic, water vapor permeability and comfort was studied. It shows that when the weight of intermediate layer changes from 40g/m^2 to 80g/m^2 , the absorbing capacity of 100cm^2 dressings is more than 16g liquid, and following the increase of the density of the intermediate layer, the water vapor permeability of the dressings tends to decrease, but the water vapor transmission rate of m2/24h is over 2. I kg. The extensibility and permanent deformation of the dressings, being parallel to the layer carding direction are greater than that is perpendicular to the layer carding direction. The extensibility of the dressings is less than 2.3N/cm and the permanent deformation is less than 13% , the dressinghas are of good comfort property.
