▎ 摘　　要

NOVELTY - Silica aerogel complex insulating fabric comprises complex fiber containing modified long fiber and a shell material, where the shell material is wrapped around the modified long fiber, and the mass ratio of the modified long fiber to the shell material is 1 -3: 5. USE - An INDEPENDENT CLAIM is also included for silica aerogel complex insulating fabric. ADVANTAGE - The complex fiber has good thermal insulation effect, high antibacterial rate, and excellent mechanical properties. The thermal insulation fabric has good washing resistance, long service life, and strong practical value. The method reduces heat preservation and antibacterial properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of silicon dioxide aerogel complex insulating fabric.
