Compression Properties of Two Novel Natural Luffa Mattress Filling Materials

ABSTRACT

Luffa is expected to become a substitute for mattress filling materials due to its natural biodegradability, light texture, good air permeability, higher water absorption, and desorption. In this paper, two-variety luffa cylinders (LCs) as mattress filling materials were investigated. The results showed that the compressive strength and plateau stress of both the high-density and low-density LCs significantly related to their density. However, the compressive strength and plateau stress of the high-density LCs were about 3 times that of the low-density LCs, while the firmness of the high-density luffa mattresses was no more than 3 times that of the low-density luffa mattresses. Furthermore, the compression treatment of the LCs has a great effect on the firmness of the luffa mattresses. The compressive treatment of the LCs to the densification stage increased the D_core of the low-density luffa mattresses but decreased the D_core of the high-density luffa mattress. The firmness of the low-density luffa mattress was lower than that of 3D jute, carvel jute, and palm mattresses.

摘要

Luffa由于丝瓜络具有天然可降解性、质轻、透气性好、吸湿散湿性好的优点，有望成为床垫的填充材料。本文研究了作为床垫填充材料的两种不同品种的柱状丝瓜络。结果表明，高密度和低密度柱状丝瓜络的抗压强度和平台应力与其密度显着相关。虽然高密度柱状丝瓜络的抗压强度和平台应力大约是低密度的3倍，但是高密度丝瓜络床垫的硬度不超过低密度丝瓜络床垫的3倍。另外，柱状丝瓜络的压缩处理对丝瓜床垫的坚固性有很大影响。低密度柱状丝瓜络经过压缩至密实化阶段处理后，低密度丝瓜络床垫的硬度增加，但高密度柱状丝瓜络压缩至密实化阶段后，由其制备的丝瓜络床垫的硬度却降低了。低密度丝瓜络床垫的硬度小于3D黄麻垫、平铺黄麻垫和棕垫的硬度。
