1：Experimental Design and Method Selection:

The study used interfacial polymerization to synthesize AZO-embedded lemon microcapsules and a padding process to coat cotton fabrics, followed by modification with silica sol for superhydrophobicity.

2：Sample Selection and Data Sources:

Scoured and bleached plain weave cotton fabric with a grammage of 117 g/m2 was used.

3：List of Experimental Equipment and Materials:

Chemicals included zinc acetate dehydrate, aluminum nitrate nonahydrate, polyethylene glycol, polyvinyl alcohol, dispersant 5040, hexamethylene diisocyanate, tetraethoxysilane, citral, guanidine carbonate, hexadecyltrimethoxysilane, and surfactant JFC. Equipment included X-ray powder diffractometer, ICP-AES, SEM, laser light particle size analyzer, TGA analyzer, gas chromatography, contact angle measurement system, UV protection factor evaluator, and UV-Vis-NIR spectrophotometer.

4：Experimental Procedures and Operational Workflow:

Synthesis of AZO nanopigments via co-precipitation, preparation of microcapsules via interfacial polymerization, treatment of cotton fabrics with microcapsules and silica sol, padding, drying, and curing.

5：Data Analysis Methods:

Characterization techniques included XRD, ICP-AES, SEM, particle size analysis, TGA, gas chromatography, contact angle measurements, UPF evaluation, and transmittance spectra analysis.
