Spacer fabric is a typical three-dimensional fabric,including upper layer,lower layer,and spacer layer.It is widely applied in protecting cushion products for unique space structure,which attributes good comfortability to infants and the disabled elderly in reducing diseases resulting from hot and humidity under long-time sitting and lying period.It necessitates studying the microenvironment change between body and clothes and corresponding performance.Compressibility,air permeability,heat and moisture permeability, and bending and humiture in microenvironment of spacer fabric are analyzed and compared with foam cushion and nonwoven cushion.Experimental results show that corresponding performance of spacer fabric is better in protecting cushion than those of foam and nonwoven.Compared with traditional foam cushion and non-woven cushion,spacer fabric is more suitable for protecting cushion,and provides an alternative and optimal cushion material in medical products to protect infants and the disabled elderly from bedsores resulted from long-time sitting and lying.
