Process Technique and Property Evaluation of Bamboo Charcoal/Polyamide/Stainless Steel Elastic Warp-Knitted Fabrics

Abstract

As improvement of science and technology, the life quality was significantly promoted. And people are more aware of health care. It has been proved that bamboo charcoal owns special properties including air purification, water refining, deodorization, far-infrared radiation, and anion release, thus it is widely applied on textile industry in form of fiber and yarn after mixing with its power. This study aims to seek for the optimal twist number of bamboo charcoal (BC)/Nylon(NY)/ stainless steel(SS) wrap yarn. And then the one or two wrap yarns were fed into crocheting machine to weave BC/NY/SS elastic warp-knitted fabrics with different structures. Afterwards, the far-infrared radiation, anion amount, air permeability were discussed by changes of number of layers. The result shows that, as increasing layers of BC/NY/SS elastic warp-knitted fabrics, the far-infrared radiation and air permeability both decrease; but all the single-layer warp knitted fabric reaches above 0.8, corresponding with the functional standards.
