“…The pre-oxidized fibres are fully released, and tangled large fibres are released in small pieces of fibres or bunches through tearing; even the single fibre state is shown. Given the poor electrical conductivity of PAN pre-oxidised fibres, which easily produce static in the process of friction with the parts, and in order to carry out the subsequent processing smoothly, pre-oxidised fibres after the opening are required to be evenly sprayed with an antistatic agent, then they are packaged for 24 hours in a plastic bag [20][21][22][23][24].…”

Many factors were needed to be considered to prepare pre-oxidised fibre felts with excellent heat insulation performance, and different production processes showed differences in the heat insulation performance of pre-oxidised fibre felts. In order to probe into the influence of the production process on the heat insulation performance of materials, a large number of experiments were needed to be carried out. For needle-punched nonwoven pre-oxidised fibre felts, web features, needle characteristics and the needle process will all affect the structure of pre-oxidised fibre felts, thus bringing a major influence on the heat insulation performance of pre-oxidised fibre felts. In this paper, the influence of the needle number on the heat insulation performance of pre-oxidised fibre felts was mainly studied. Results showed that an increase in the needle number will cause a decrease in the thickness and gram weight of pre-oxidised fibre felts, and a weakening trend in the heat insulation performance of pre-oxidiaed fibre felts with an increasing needle number at room temperature and at 100-200 °C was shown. Moreover when the needle number was 1 and 2, the pre-oxidised fibre needled felts had good heat insulation performance, and for pre-oxidized fibre felts at different needle numbers with increasing temperature, the temperature difference in a steady state increased linearly.
