The invention relates to a manufacture process for a composite heat insulation material, which has the steps that: 1,
feather is firstly washed by water, sterilized, dried and loosened, and then,
feather stems and
feather silks are separated; 2, meldable fibers and
polyester staple fibers are loosened and are mixed according to a weight ratio of 16 to 19 / 10 to 15; 3, the processed feather silks and the fibers mixed in the second step are mixed and are uniformly mixed through a stirring
machine, and in addition, some impurities are removed; 4, the feather silk mixed fibers are sewed into blocky materials by duck down threads via a patterning
machine; 5, then, the sewed feather silk mixed fibers are processed into thin sheets with the thickness being 0.3mm to 0.5mm through a
carding machine, and the impurities are removed for a second time; 6, the feather silk mixed fibers are overlapped and paved layer by layer by a net paving machine; and 7, the feather silk mixed fibers are baked by an
infrared baking oven, the baking temperature is set to 100 DEG C to 140 DEG C, and in addition, the
cutting treatment is carried out, so the initial product breadth maintains the constant value. The composite heat insulation material has good heat insulation performance, the environment is protected, the spinnability and the shearing performance are realized, the price is relatively low, the
raw material resources are rich, and the market demand potential is huge.
