摘要:	由於纖維狀材料具有高粉塵微粒過濾效率及低壓損的特性，而被廣泛地用在過濾基材上。顆粒狀或纖維狀的活性碳也常被複合於過濾基材內，為了增加化學分子及臭氣等吸附性能，然而活性碳複合技術同時影響到活性碳被握持之固著能力及吸附效能。用樹脂混合活性碳顆粒，然後將過濾基材含浸，是一般將活性碳顆粒複合於過濾基材的技術，但由於活性碳表面孔隙被樹脂覆蓋大部份，進而大幅降低吸附效能。本文係將熔噴不織布與纖維狀活性碳混合的新製程。以纖維狀活性碳之混合比率（15%, 30%及45%）為此製程之變數。此製程中，係使用自行設計、連續式之設備而且以物理性質、氣體吸附量及過濾效率做不同比率纖維狀活性碳及含浸活性碳濾布之比較。 Fibrous materials are widely used for filter media because of their high particle filtration efficiency (FE) and low-pressure drop. Activated carbon particles or fibers are frequently inserted into the filter media for adding the adsorption ability to odours and chemical vapors. However, the insertion techniques affect the holding capability of the activated carbon materials in the substrate fibers and therefore the application of the composite, as well as the adsorption ability. Mixing of latex with the carbon particles and then dipping of the mixture with the filter media is a very common technique to insert the carbon particles into the filter media. However, the adsorption strength of the carbon particles is reduced by the coverage of latex on the meso-pores of the carbon particles. This project uses three different weight ratios, viz., 15%, 30% and 45%, of activated carbon fibers (ACF) embedded into the meltblowing PP fiber stream to make the filter composite on the meltblowing line. The FE and the chemical vapor adsorption ability in terms of break-through and saturation times of these composites of activated carbon fibers as well as the latex-dipped composite of carbon particles will be presented. The carbon fiber insertion processes and the experimental results will be discussed.
