Moisture-absorbing thermal-insulation down composite fiber and manufacturing method thereof

Abstract

The invention discloses a moisture-absorbing thermal-insulation down composite fiber which is prepared from the following raw materials in parts by weight: 10-15 parts of goose down, 20-24 parts of wool, 16-18 parts of cowhair, 10-12 parts of French cotton, 6-9 parts of mulberry fiber, 8-10 parts of kendir fiber, 11-14 parts of plush fiber, 12-15 parts of lotus leaf, 2-4 parts of radix polygonati officinalis, 1-3 parts of rhizoma polygonati, 3-5 parts of medical stone, 4-6 parts of Shea Butter extracting solution, 0.03-0.06 part of sodium dodecyl benzene sulfonate, 0.4-0.8 part of polyethylene terephthalate, 0.7-1.2 parts of glycerol, 120-130 parts of 1-butyl-3-methylimidazole acetate, 110-120 parts of dibutyl 1-butyl-3-methylimidazole phosphate, 3-5 parts of assistant and a right amount of water. The down composite fiber has the characteristics of high flexibility, light weight, favorable elasticity, favorable moisture-absorbing and thermal-insulation properties, uniform and fine structure, favorable appearance quality and the like, and can be popularized and applied in the field of textiles or non-textiles.

Description

technical field [0001] The invention relates to the technical field of non-woven materials, in particular to a moisture-absorbing and heat-retaining 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 fie...

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
