Down composite fiber composited with waste down fiber/acrylic staple fiber and its production method

Abstract

The invention discloses a down feather composite fiber compounded by waste down feather fiber and acrylic staple fiber. The down feather composite fiber compounded by the waste down feather fiber and the acrylic staple fiber is prepared from the following raw materials in parts by weight: 10-15 parts of superfine goose down powder, 20-25 parts of waste down feather fiber, 25-30 parts of nano goose feather powder, 18-20 parts of acrylic staple fiber, 14-17 parts of collagen fiber, 7-9 parts of nano bamboo charcoal powder, 17-21 parts of coconut shell, 0.3-0.6 part of magnesium oxide, 1-3 parts of perilla frutescens bark, 2-4 parts of rhizoma smilacis glabrae, 13-15 parts of rice straw pulp fiber, 100-120 parts of 1-butyl-3-methyl imidazole dibutyl phosphate, 120-140 parts of 1,3-dimethyl imidazole dimethyl phosphate, 2-4 parts of additives and a proper amount of water. According to the down feather composite fiber compounded by the waste down feather fiber and the acrylic staple fiber, the waste down feather fiber is effectively used; the cost is reduced; meanwhile, perilla frutescens bark and rhizoma smilacis glabrae are added in the down feather composite fiber, so that the mildew and moth of the down feather composite fiber during the storage, transportation and utilization of the down feather composite fiber can be effectively avoided; especially, after the down feather composite fiber is used as a filler and made into articles of daily use, due to the bacteria resistance and bacteriostasis of the down feather composite fiber, the corresponding products have the obvious antibacterial, anti-inflammatory, deodorant, mildew-proof, anit-pruritic and astringent functions, have no stimulation to the skin and are well received by consumers.

Description

Technical field [0001] The invention relates to the technical field of non-woven materials, in particular to a down composite fiber composed of waste down fiber / acrylic short fiber and a manufacturing method thereof. Background technique [0002] Down is a flower-like fluff that grows on the abdomen of geese and ducks, and the flakes are called feathers. Because down is an animal protein fiber, it has higher thermal insulation properties than cotton (vegetable cellulose), and the down ball-shaped fiber is densely covered with thousands of small triangular pores, which can shrink and expand with changes in temperature, resulting in a thermoregulation function. It absorbs the flowing heat from the human body and isolates the intrusion of cold air from the outside. Due to the unique soft warmth and moisture absorption and dissipation of the down, it determines the good health function of the down. The down quilt is widely used in clothing, quilt, and textile filler. And other field...

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
