A composite fiber web having superior heat resistance and sound absorption and including a center layer containing a carbon fiber and a heat-resistant layer, and to a method of manufacturing the same. The method of the present invention can exhibit a fast manufacturing speed through a melt-blowing process that will generate economic benefits. The composite fiber web includes a composite layer and individual layers with various fiber diameters resulting in a superior sound absorption rate. The PET fiber included in the heat-resistant layer of the composite layer is an environmentally friendly material with superior heat resistance due to the inclusion of ultrafine fiber. Also, the composite fiber web has superior strength, conductivity, and electromagnetic shielding and deodorization effects, which allows it to be widely utilized for sound absorption materials and in all application fields thereof.

Disclosed is a coating composition for preventing odor. The coating composition may include one or more types of odorless microorganisms selected from the group consisting ofandor a culture solution thereof. Further provided is a method for preventing odor, and the method may include applying the coating composition for preventing odor. When a biofilm is formed from the microorganisms in the coating composition by coating an object on which an odor-causing microorganism can live, the inflow and the inhabitation of external microorganisms generating odor may be significantly blocked, thereby enabling odor to be effectively prevented.

Composition for preventing odor, containing odorless microorganisms

The present invention relates to a composition for preventing odors containing odorless microorganisms or a culture thereof. The present invention also relates to a method for preventing odors including coating the composition for preventing odors. When a biofilm is formed by coating an object offensive odor-generating microorganisms can inhabit with the composition for preventing odors of the present invention, odors can be effectively prevented by significantly preventing the inflow and inhabitation of outside microorganisms that may generate offensive odors.

Composition for preventing odors containing odorless microorganism
