Study on the Characteristics of Kapok Yarn and Its Antibacterial and Constant-temperature Properties

Abstract

This study aims to explore the physical, chemical, and thermal properties of kapok fiber, as well as its antibacterial and constant-temperature properties via experiments. The cross-sectional structure of kapok fiber was observed using a microscope, and its thermal property was determined using thermogravimetric analysis (TG) and differential scanning calorimetry (DSC). Additionally, antibacterial tests were conducted using Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), while changes in the physical properties of kapok fiber after blending were analyzed. It was found that kapok fiber possesses a unique hollow structure and excellent warmth retention property, with an initial decomposition temperature of 296℃, indicating good thermal stability. Kapok fiber exhibited significant antibacterial effects against both E. coli and S. aureus. Blending kapok fiber with cotton fiber significantly enhanced the moisture absorption and conduction, and warmth retention properties of the fabric. In conclusion, kapok fiber is a natural and eco-friendly fiber with excellent antibacterial and warmth retention properties. When blending with cotton fiber, it improves the physical and hygienic properties of textiles.
