Waterproof down feather composite fiber and preparation method thereof

Abstract

The invention discloses a waterproof down feather composite fiber. The waterproof down feather composite fiber is characterized by being prepared from the following raw materials in parts by weight: 10-15 parts of duck's down, 16-21 parts of rabbit hair, 15-17 parts of merino super fine wool, 8-10 parts of gabardine fibers, 3-5 parts of acetate fibers, 0.1-0.3 part of zinc oxide, 0.4-0.8 part of methyl sodium silicate, 2-4 parts of kieselguhr, 1.2-2.3 parts of polystyrene foam particles, 1-3 parts of gastrodia elata, 0.6-0.9 part of prunella vulgaris, 0.8-1.3 parts of mint, 3-5 parts of melon vine, 4-7 parts of epoxy butyl oleate, 100-115 parts of 1-butyl-3-methyl imidazole acetate, 105-115 parts of 1-butyl-3-methyl imidazole dibutyl phosphate, 2-4 parts of additives and a proper amount of water. Polystyrene foam particles, methyl sodium, gastrodia elata, prunella vulgaris, mint and other ingredients are added; the technology is simple, convenient and feasible, and is low in production cost; the prepared down feather composite fiber has the advantages of water prevention, bacteria resistance, bacteriostasis, mildew and moth prevention and the like, so that the down feather composite fiber has no odor in using, and is clean and sanitary.

Description

technical field [0001] The invention relates to the technical field of non-woven materials, in particular to a waterproof down composite fiber and a manufacturing method thereof. Background technique [0002] Down is the fluff that grows on the abdomen of geese and ducks, and is called feathers in flakes. Because down is a kind of animal protein fiber, it has higher thermal insulation than cotton (vegetable cellulose), and the down ball-shaped fiber is densely covered with tens of thousands of small triangular pores, which can shrink and expand with temperature changes, resulting in a temperature-regulating function. It absorbs the flowing heat from the human body and isolates the invasion of cold air from the outside. Because down has this unique performance of soft warmth and moisture absorption and divergence, it determines the good health care function of down. Down quilts are widely used in clothing, quilts, and textile fillers. and other fields. [0003] There are ma...

Problems solved by technology

[0003] There are many defects in the use of natural down in the prior art: one, because the content of down in feathers is very small, usually only accounting for 20-25%, so that the use cost of down is too high; Improper easy to mildew and grow mites; 3, the strength is poor, too much washing will make the eiderdown pulverized, agglomerated, reduce the warmth retention, and affect the appearance; 4, the eiderdown in t
