Research On Properties And Development Of The Fabrics Made Of Bamboo-charcoal Modified Polyester

Bamboo-charcoal modified polyester, a brand-new fabric material, is becoming more and more popular with the consumers because of its environment friendly and special functional properties. So a systematic study of bamboo-charcoal polyester, its products performance and the development of bamboo-charcoal polyester fiber products will be of great significance.In this paper, digital image processing principle combined with MATLAB image processing toolbox are used to determine charcoal polyester's porosity. The result proves that rich pore exist in it and it has good properties of moisture absorbing and releasing. This paper drawn some conclusions about mechanical properties by testing some bamboo-charcoal modified yarns, bamboo-charcoal polyester/cotton blended yarns and some pure cotton yarns. The conclusions show that bamboo-charcoal modified polyester yarns have excellent tensile property and low first module. It means that bamboo-charcoal modified polyester has high flexibility. We design experiment scheme and product process rationally and make eight kinds of fabrics with the ASL2000 automatically rapier loom. The fabrics are made of different fiber fineness and different weft density. Through testing these fabrics, we come to the conclusions that bamboo-charcoal modified polyester fabrics have good absorbability and drapability. However, the gas permeability of the bamboo-charcoal modified polyester fabrics is inferior to that of the cotton ones. In the view of product development, suitable bamboo-charcoal modified polyester content is 30%～35% in the fabric.On the basis of the above research and analysis, we choose better techniques in areas of raw materials, fabrics structure, dyeing and finishing processes to make new antibacterial products. By this way, the fabrics'permeability and drapability improve apparently and it achieves to designed purpose.
