During the past few years there have been increasing concerns relating to the performance of bandages, especially their pressure distribution properties for the treatment of venous leg ulcers. This is because compression therapy is a complex system and requires two or multi-layer bandages, and the performance properties of each layer differs from other layers. The widely accepted sustained graduated compression mainly depends on the uniform pressure distribution of different layers of bandages, in which textile fibres and bandage structures play a major role. This article examines how the fibres, fibre blends and structures influence the absorption and pressure distribution properties of bandages. It is hoped that the research findings will help medical professionals, especially nurses, to gain an insight into the development of bandages. A total of 12 padding bandages have been produced using various fibres and fibre blends. A new technique that would facilitate good resilience and cushioning properties, higher and more uniform pressure distribution and enhanced water absorption and retention was adopted during the production. It has been found that the properties of developed padding bandages, which include uniform pressure distribution around the leg, are superior to existing commercial bandages and possess a number of additional properties required to meet the criteria stipulated for an ideal padding bandage. Results have indicated that none of the mostly used commercial padding bandages provide the required uniform pressure distribution around the limb.
在过去几年里，人们越来越关注绷带的性能，尤其是其在治疗下肢静脉溃疡时的压力分布特性。这是因为压迫疗法是一个复杂的系统，需要两层或多层绷带，而且每层的性能特性都与其他层不同。广泛接受的持续梯度压迫主要取决于绷带不同层的均匀压力分布，其中纺织纤维和绷带结构起着主要作用。本文研究了纤维、纤维混纺物和结构如何影响绷带的吸收和压力分布特性。希望这些研究结果能帮助医学专业人员，尤其是护士，深入了解绷带的发展。使用各种纤维和纤维混纺物制作了总共12种填充绷带。在生产过程中采用了一种新技术，该技术有助于实现良好的弹性和缓冲性能、更高且更均匀的压力分布以及增强的吸水性和保水性。已发现所开发的填充绷带的性能，包括腿部周围的均匀压力分布，优于现有的商业绷带，并具有满足理想填充绷带规定标准所需的许多其他特性。结果表明，大多数常用的商业填充绷带都不能在肢体周围提供所需的均匀压力分布。
