Polyester fibers tend to generate static electricity during the weaving and application processes, posing a threat to their production. Enhancing the water absorbency and electrical conductivity of polyester fibers themselves is an effective approach to improving their antistatic properties. In this study, multifunctional chitosan (CS), sodium phytate (SP), and Cu²⁺ were loaded on polyester fibers through layer-by-layer (LBL) self-assembly. The antistatic and water absorption capability of the modified polyester fibers was investigated by designing different process parameters combined with a surface resistance test and water contact angle tests. The antistatic property test results confirmed the positive effect of CS and Cu²⁺ on discharging electrostatic charge. Within a definite scope, with the increase in the number of assembly layers, assembly duration, and the concentration of the assembly substances, the wettability of the modified polyester fibers became more favorable and the antistatic effect became more remarkable.

This study investigates the effect of incorporating lavender microcapsules into flooring coatings on the surface properties of the flooring. The experimental results indicate that after adding lavender microcapsules, the flooring’s color, gloss, wear resistance, and hydrophobicity experienced slight changes, with a color difference (ΔE) below 2 units, gloss decreasing by 8%, and wear resistance reducing by approximately 5%. However, these changes were within an acceptable range. Chemical composition analysis confirmed the fragrance-releasing effect of the lavender microcapsules. Furthermore, scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) verified the structural integrity of the microcapsules and their effective fragrance release. This study demonstrates that the introduction of lavender microcapsules not only enhances the scent perception of the flooring but also achieves long-term fragrance release while maintaining its fundamental physical properties, highlighting its potential for practical applications.
