Warm down feather composite fiber and producing method thereof

Abstract

The invention discloses a warm down feather composite fiber which is characterized by comprising the following raw materials by weight: 12-14 parts of goose down, 19-24 parts of goose feather, 13-16 parts of dog hairs, 10-13 parts of cypress fiber, 12-14 parts of bamboo pulp fiber, 7-9 parts of short acrylic fiber, 0.4-0.8 parts of butyl acrylate, 0.2-0.4 parts of butyl acrylate, 2.1-3.4 parts of expanded and vitrified small ball, 2-3 parts of peanut shell, 3-5 parts of bamboo leaf, 1-2 parts of lobelia, 2-4 parts of wild chrysanthemum, 0.4-0.8 parts of rhizoma anemarrhenae, 3-6 parts of fungacetin, 100-110 parts of 1-butyl-3-methyl imidazole dimethyl phosphate, 105-115 parts of 1-butyl 3-methyl imidazole acetate, 3-5 parts of an auxiliary, and proper amount of water; the prepared warm down feather composite fiber has good heat preservation effect, does not stimulate the skin, and is safe, environmentally-friendly, excellent in antibacterial properties and washable.

Description

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

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
