In view of different deodorization fabrics and source gases,the detector tube method and gas chromatography-flame ionization detector ( GC-FID ) method were chosen to test the deodorizing rates of fabric and the influencing factors on deodorization test were discussed. Through the two methods,the residual concentration of odorous substance after adsorption can be measured,and the deodorizing rates of deodorization fabric can be got by calculation. The results show that the two test methods are both appropriate for deodorization test of fabric.展开更多
