So in this paper, thedaily lifte. In view of diterent deodorization fabrics and sourcetypical gases were used for testing by detector tube method andgases, tbe detector tube method and gas chromatography-MameGC-FID method 11-3]. Although GC-FID method is widelydendorsineratesorfabriememoowerecoosentotestmneused in the qualitative and quantitative testing of organicdeodorization test were discussed. Through the two methods, thesubstance, the parameter of GC-FID should be optimized in theresidual concentration of odorous substance after adsorption can betest, because of the lower relative molecular mass of ammoniameasured，and the deodorizing rates of deodorization fabric can beand fommaldehyde. Meanwhile, the low solubility of hydrogengot by calculation. The results show that the two test methods aresuifide in kinds of solvents makes it be tested only by detectorboth appropriate for deodorization test of fabric.tube method.Key words: deodorization fabric; deodorizing rate; detector tube; gaschromatography-flame ionization detector ( GC-FID)1.1 MaterialsCLC number: TS107.3Document code: AThe blank sample， cotton interfacing， bamboo-carbonArticle D: 1672 5220(2012 )03 026804fabric with silver ions， bamboo-carbon fabric， and hempstocking were chosen to study the test method of the fabricdeodorization，and were indicted by 1, 2, 3, 4，and 5Introductionrespectively: l -blank sample, 2 -cotton interfacing ( ShanghaiTextile Industry of Technical Supervision, China), 3 -bamboo-There are a lot of microorganisms around people and theycarbon fabric with silver ions ( Wuxi Paiho Textile Ltd,act frequently in a certain temperature and humidity ,China), 4- bamboo-carbon fabric ( Wuxi Paiho Textile Ltd. ,decomposing the protein, carbohydrate, higher fatty acid, andChina), 5-hemp stocking ( Donghua University, China) .something else from human body. While the odor 0Ammonia/ nitrogen standard substance: the concenrationdecomposition spreads in the air and goes into the nasal cavity ofof ammonia for 75. 9 mg/m3 under 9.5 MPa，produced byhuman body, it is adsorbed by smell cells of the upper nasalShanghai Weichuang Standard Gas Co， Ltd.， China;cavity causing membrane potential which is sent into the brain asformaldehyde/ nitrogen standard substance: the concentration ofpulse signal along the nerves. Therefore, people can feel theformaldehyde for 133. 9 mg/ m3 under 9. 5 MPa, produced bydirty smell[1]. The dirty smell refers to the unpleasant odor forShanghai Weichuang Standard Gas Co, Ltd, China; hydrogenmost people. And the root of the dirty smell is mostly from thesulfide/ nitrogen standard substance: the concentration ofdecomposition of microorganisms. Faced with the dirty smell,hydrogen sulfide for 151. 8 mg/m3 under 9.5 MPa, producedwe use variety of methods to eliminate stink for comfort [2-4]by Shanghai Weichuang Standard Gas Co.， Ltd， China;including developing antibiosis deodorization fabric Is, 6]physical coating [7,8] , and photo catalyst [9, 10] and so on. Soethanol alcohol: analytically pure, produced by SinopharmChemical Reagent Co.， Ltd.， China; ammonia solution:far, more and more deodorization fabric products enter theanalytically pure, 28% by weight, produced by Shanghai Anpumarket as the demands of people. But it's hard for consumers toScientific Instrument Co, Ltd, China; formaldehyde solution :distinguish them.
