This study focuses on the performance optimization of honeycomb structure insulation layer. Laser cutting technology was used to prepare insulation layers of different profiles on non-woven fabric, and it was found that the honeycomb fabric system has better thermal protection compared to the conventional solid fabric system. A-type structure showed superior thermal protective performance compared to I-type structure.
The insulating layer of the hollow structure of thermal protective clothing plays a positive role in weight and thermal protection. The relationship between the hole shape and the performance of the hollow structure is of great importance to optimization. This paper focuses on the performance optimization of the honeycomb structure insulation layer. Laser cutting technology was used to cut the hole in the non-woven fabric. The thermal insulation layers of five common three-dimensional sections were prepared by the multi-layer composite method. Compared with the conventional solid fabric system, the honeycomb fabric system has better thermal protection. At the same time, the section structure also affects the thermal protection performance. The developed A-type structure possesses a superior Thermal Protective Performance value in comparison to I-type straight structure. It has lower moisture resistance and higher total heat loss. The thermal protection of A-type section structure, together with excellent thermal and moisture comfort, make it put forward the improvement direction for the structural optimization of commercial nonwovens where the balance between thermal protection and thermal and moisture comfort is the key requirement.
