A kind of mothproof eider down composite fibre and preparation method thereofTechnical field
The present invention relates to nonwoven material technical field, be specifically related to a kind of mothproof eider down composite fibre and preparation method thereof.
Background technology
Eider down is the long belly goose, duck, becomes the fine hair of a reed catkins shape, slabbing be feather.Because eider down is a kind of animal protein fiber, higher than cotton (vegetative fiber element) heat insulating ability, and ten million leg-of-mutton tiny pore that eider down nodular fibrous gathers, can the convergent-divergent with temperature Change, produce temperature adjustment function, Absorbable rod human body distributes the hot gas of flowing, the invasion of isolated cool ambient air, because eider down has the superperformance that the softly warming of this uniqueness and moisture absorption disperse, determine the health care that eider down is good, eiderdown quilt be widely used in clothes, wadded a quilt with cotton, the fields such as filler of weaving.
Natural down is used to there is many defects in prior art: one, because eider down content in feather is little, usually only to account for 20-25%, thus make the use cost of eider down too high; Two, eider down makes moist because of the humidity of environment, preserves the improper raw mite that easily goes mouldy; Three, intensity is poor, can make eider down pulverizing, conglomeration, reduce warmth retention property, affect attractive in appearance more than washed; Four, the frequent static electrification of eider down in prior art, brings inconvenience; Five, existing eider down does not have the characteristics such as fire-retardant, antibacterial, water-fastness, there is the hidden danger such as safety, so develop a kind of existing environmental protection, health care, the warmth retention property being conducive to again the health of people is strong, high strength, fire-retardant, antibacterial, laundry-resistant eider down composite fibre can solve the deficiencies in the prior art smoothly.
Summary of the invention
Object of the present invention is just to provide a kind of mothproof eider down composite fibre and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
A kind of mothproof eider down composite fibre, it is characterized in that, be made up of the raw material of following weight portion: duck's down 16-18, chicken feather 15-19, mercerized wool fiber 11-13, mercerized cotton fiber 12-14, copper ammonia fibre 4-7, rice straw 15-19, closed perlite powder 4-6, Radix Angelicae Sinensis 1-3, rhizoma Gastrodiae 2-4, Ligusticum wallichii 2-3, zinc gluconate 0.2-0.4, alumina silicate 0.3-0.6,1-butyl-3-N-Methylimidazoleacetic salt 100-105,1-butyl-3-methylimidazole dibutylphosphoric acid ester 110-115, auxiliary agent 2-4, suitable quantity of water.
Described auxiliary agent is made up of following raw materials in part by weight: polymer dispersion powder 1-2, even bubble silicone oil 3-4, Benzotriazole Ultraviolet Stabilizer 0.03-0.05, polyvinylpyrrolidone 0.2-0.4, trihydroxy ethylamine oleate soap 1.2-3.4, kuh-seng 1-3, erythrina bark 2-4, camphor 0.1-0.3, water 100, its preparation method is by kuh-seng, erythrina bark, camphor boiling 3-5 hour obtained the concentrated liquid of tradition Chinese medicine, filter, in filtrate, add other residual componentss be heated to 45-55 DEG C of agitation grinding 20-30 minute, to obtain final product.
The preparation method of described a kind of mothproof eider down composite fibre, is characterized in that comprising the following steps:
(1) by Radix Angelicae Sinensis, rhizoma Gastrodiae, Ligusticum wallichii, rice straw boiling 4-6 hour, filter, get filter residue and dry pulverizing, add 10% sulfuric acid heating stirring reaction 1-2 hour of filter residue powder 20 times of quality in mass ratio, add the NaOH heating stirring reaction 1-2 hour of filter residue powder 2 times of quality again, cooling, filters, with clear water washing to totally also, add zinc gluconate grinding 20-40 minute;
(2) duck's down, chicken feather, mercerized wool fiber are dropped in above-mentioned filtrate and soak 10-13 hour, after pulling oven dry, degreasing, ultra-fine grinding out, add the grinding of the closed perlite powder after high-temperature calcination process 40-50 minute;
(3) take 1-butyl-3-N-Methylimidazoleacetic salt, 1-butyl-3-methylimidazole dibutylphosphoric acid ester drops in reactor and stirs and evenly mixs, add mercerized cotton fiber, copper ammonia fibre, step (1), (2) product grinding 20-40 minute, be heated to 100-120 DEG C, add other residual components stirring reaction 50-70 minute, obtained spinning solution;
(4) finally obtained spinning solution carried out spinning, winding, boundling, stretching and get final product.
The present invention has following beneficial effect: the eider down composite fibre that the present invention obtains has the advantages such as sterilization is mothproof, light weight intensity is high, heat-insulating and fire-proof.
Detailed description of the invention
The mothproof eider down composite fibre of described one, it is characterized in that, be made up of the raw material of following weight portion: duck's down 17, chicken feather 18, mercerized wool fiber 11, mercerized cotton fiber 13, copper ammonia fibre 4, rice straw 15, closed perlite powder 4, Radix Angelicae Sinensis 3, rhizoma Gastrodiae 2, Ligusticum wallichii 3, zinc gluconate 0.2, alumina silicate 0.3,1-butyl-3-N-Methylimidazoleacetic salt 100,1-butyl-3-methylimidazole dibutylphosphoric acid ester 115, auxiliary agent 2, suitable quantity of water.
Described auxiliary agent is made up of following raw materials in part by weight: polymer dispersion powder 1, even bubble silicone oil 3, Benzotriazole Ultraviolet Stabilizer 0.04, polyvinylpyrrolidone 0.2, trihydroxy ethylamine oleate soap 1.7, kuh-seng 1, erythrina bark 2, camphor 0.1, water 100, its preparation method is by kuh-seng, erythrina bark, camphor boiling 3-5 hour obtained the concentrated liquid of tradition Chinese medicine, filter, in filtrate, add other residual componentss be heated to 45-55 DEG C of agitation grinding 20-30 minute, to obtain final product.
Preparation method comprises the following steps:
(1) by Radix Angelicae Sinensis, rhizoma Gastrodiae, Ligusticum wallichii, rice straw boiling 4-6 hour, filter, get filter residue and dry pulverizing, add 10% sulfuric acid heating stirring reaction 1-2 hour of filter residue powder 20 times of quality in mass ratio, add the NaOH heating stirring reaction 1-2 hour of filter residue powder 2 times of quality again, cooling, filters, with clear water washing to totally also, add zinc gluconate grinding 20-40 minute;
