The invention relates to the technical field of application of silk resources, in particular to a silk composite flocculus for
processing of light, thin and highly heat-insulating clothes. The production process of the silk composite flocculus includes: (1), pretreating silk fibers; (2), weighing and opening the silk fibers and novel highly heat-insulating fibers, and then evenly mixing the both; (3),
carding the mixture into a net; (4), drafting
clutter; (5), fixing the flocculus; (6), finishing; (7), slitting and packaging. The silks are composited with the novel light, highly elastic and highly heat-insulating fibers to develop the silk composite flocculus which is light, highly heat-insulating and easy to maintain, and the advantages of the natural silks and the high-performance heat-insulating fibers are combined, so that the requirements of people on comfortableness, health care function, light weight, thinness and heat insulation of winter clothes can be met, and the defects of low fluffiness, softness and
compression ratio and hard hand feel of flocculi in the prior art can be overcome.
