Deodorizing for fiber and fabric: Adsorption, catalysis, source control and masking

Textile with deodorizing properties not only keeps the clothing smell fresh, but also is beneficial toward improving the level of indoor air quality, especially when the fibrous materials are used for buildings and furniture. This review summarizes and discusses the recent progress in developing smart textile with deodorizing property. In particular, the key deodorizing methods including enhanced adsorption, catalytic decomposition, source control and masking are brought to light. The theoretical concepts, mechanisms and the latest fabrication methods along with the deodorizing efficiency are discussed. Moreover, the current limitations of these methods are underlined and some recommendations for future research strategies in terms of deodorizing performance, textile engineering, fiber types and treatment impact on fiber mechanical properties are proposed. This review provides the latest state-of-the-art achievements in the field of deodorizing methods of textile, which will be a valuable platform for researchers and decision makers to design and develop novel functional textile products.
