A Study on the Development, Properties, and Sustainable Potential of Kapok–Silk Blended Fabrics for Babywear and Thermal Wear

Kapok fiber, derived from the seed hairs of Ceiba pentandra, is an ultra-light, hollow, and biodegradable natural fiber recognized for its thermal insulation, water resistance, and sustainability. When combined with silk—an animal protein-based fiber known for its strength, sheen, and comfort—a novel textile blend can be developed that caters to both fashion and technical textile applications. This study investigates the potential of kapok–silk blended textiles by focusing on their structural compatibility, performance characteristics, and environmental benefits. The research explores the blending process, addresses processing limitations, and evaluates fabric properties such as thermal insulation, breathability, softness, and biodegradability. Special attention is given to the blend’s applicability in babywear and thermal wear, aiming to offer an innovative and eco-conscious alternative to conventional textiles. This study contributes to the growing demand for sustainable fabrics in both high-performance and sensitive-skin
