Abstract

The invention discloses an aerogel composite fiber and a manufacturing process thereof. The manufacturing process comprises the following steps: mixing an aerogel PET (Polyethylene Terephthalate) master batch and a PET chip according to a ratio of 1:(5-10), and melting to form a spinning melt under the melt temperature of 285-290 DEG C and the melt pressure of 1-2MPa; drawing the spinning melt to form nascent fibers, and finally stretching the nascent fibers, thereby obtaining the aerogel composite fiber. The aerogel PET master batch and the PET chip are taken as production materials, and the characteristics of good heat-insulating property of aerogel and high toughness and high wear resistance of the PET material are combined, so that the produced aerogel composite fiber is high in toughness. Meanwhile, the heat conductivity coefficient of the aerogel composite fiber is 0.032W / (m*K) and is much lower than the heat conductivity coefficient 0.092W / (m*K) of pure wool. Therefore, ready-to-wear made from the aerogel composite fiber has excellent heat retaining property.
