Mothproof down feather composite fiber and preparation method thereof

Abstract

The invention discloses a mothproof down feather composite fiber. The mothproof down feather composite fiber is characterized by being prepared from the following raw materials in parts by weight: 16-18 parts of duck's down, 15-19 parts of chicken feather, 11-13 parts of mercerized wool fibers, 12-14 parts of mercerization cotton fibers, 4-7 parts of copper ammonia fibers, 15-19 parts of straw stalk, 4-6 parts of closed cell perlite powder, 1-3 parts of angelica sinensis, 2-4 parts of gastrodia elata, 2-3 parts of ligusticum wallichii, 0.2-0.4 part of zinc gluconate, 0.3-0.6 part of aluminium silicate, 100-105 parts of 1-butyl-3-methyl imidazole acetate, 110-115 parts of 1-butyl-3-methyl imidazole dibutyl phosphate, 2-4 parts of additives and a proper amount of water. The down feather composite fiber prepared by the invention has the advantages of sterilization, moth prevention, light weight, high intensity, thermal preservation, flame retardance and the like.

Description

technical field [0001] The invention relates to the technical field of non-woven materials, in particular to a mothproof 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 man...

AI Technical Summary

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 the prior art is often charged with static electricity, which brings inconvenience to people; 5. The existing down has no characteristics such as flame-retardant, antibacterial, and water-resistant, and there are hidden dangers such as safety. Therefore, a kind of thermal insulation, high strength, flame-retardant, antibacterial, The washable down composite fiber can successfully solve the deficiencies of the prior art
