    The adsorption of particles on cotton affects its performance. Investigating the factors that affect particle adsorption on cotton can provide valuable insights into the adsorption process. By characterizing morphology, composition, structure, surface energy, and specific surface area, this study explores the adsorption of poly (butyl methacrylate) (PBMA) nanocapsules (NCs) on cotton via impregnation, including a preliminary study on the effect of concentration on adsorption. The results yield the following conclusions: (i) the viscosity of the PBMA emulsion increases with concentration, resulting in heightened particle adsorption on cotton and a thicker film after drying; (ii) the acidity and heat resistance of the cotton increase, owing to the formation of hydrogen bonds between the hydroxyl groups in PBMA and cotton and the increased hydrogen bonding interactions with adsorption; (iii) although the adsorption of PBMA NCs on cotton fibers causes a slight decrease in crystallinity and crystal plane spacing, the cotton retains impressive hydrophilicity, wettability, air permeability, and a porous structure. Based on these results, the study proposes a novel approach for the development of functional textiles.
