Why Do Some Fabrics Absorb Odors?

Ever notice that some clothes seem to trap odors no matter how often you wash them? The fabric itself plays a big role in odor absorption and retention. Natural fibers like cotton and wool are breathable and tend to release smells when washed properly, while synthetic fabrics like polyester trap sweat and bacteria, leading to lingering odors. Beyond just the smell factor, synthetic fabrics can also expose you to harmful chemicals and even contribute to microplastic pollution. Choosing natural, breathable fabrics can help you stay fresh and reduce health risks—because what you wear matters just as much as what you eat!
