Embodiment Construction
[0014] Non-limiting examples of the present invention are as follows:
[0015] A down composite thermal insulation material containing pineapple leaf fiber is prepared from the following components and raw materials by weight (kg):
[0016] Duck down 35, pineapple leaf fiber 12, polylactic acid composite fiber 15, polyvinyl alcohol fiber 8, konjac glucoside 0.3, sodium lauroyl sarcosinate 0.15, nano-silica 0.15, peanut oil 1.5, water 12;
[0017] The polylactic acid composite fiber is prepared from the following raw materials in parts by weight: polylactic acid 45, shell powder 5, glycerin 6, silane coupling agent KH-550 0.4; the preparation method of the polylactic acid composite fiber is to mix the shell powder. After mixing with silane coupling agent KH-550, it is treated at 100 °C for 1 hour. After cooling, it is mixed with the rest of the raw materials evenly. Spinning, that is.
[0018] The preparation method of the down composite thermal insulation material containing...
