  Abstract

This research aims at developing novel thermal protective fabrics with three-dimensional spacer woven structure, using basalt fibers and polyimide fibers. Different properties of three-dimensional spacer woven fabrics were discussed, such as flame retardant, thermal insulation, thermal protection performance and thermal stability. In addition, the effects of spacing heights on different thermal protection properties were also explored. The limiting oxygen index and vertical burning tests were used to evaluate flame retardant performance. Results demonstrated that the LOI value of the outer basalt fabric is greater than 69% and that of the inner polyimide fabric is greater than 35%, indicating an excellent flame retardant property. The thermal insulation performance of fabrics was characterized by the thermal resistance and insulation rate. Results confirmed that the insulation rate and thermal resistance of fabric spaced at a height of 0 mm are much lower than other fabrics with spacer yarn height, which means that the thermal insulation performance of three-dimensional fabrics has been greatly improved compared with two-dimensional fabrics. In terms of thermal protection performance, the fabric with a spacing height of 8 mm has the highest TPP value and consequently shows the best thermal protection performance. Furthermore, the shape and quality of the sample are stable after heat treatment, suggesting that the designed fabric has good thermal stability. Finally, the heat transfer process of the fabric was observed by performing numerical simulations at high temperature on fabrics with a spacing height of 8 mm. The simulation results showed that the air layer in the middle of the fabric acted as a heat insulation barrier, which makes the heat transfer slower and thus effectively improves the thermal protection performance of the fabric.
