To solve the deficiencies in the prior art, the purpose of the present invention is to provide a kind of fire-retardant down fiber and its preparation sides
Method.Fire-retardant down fiber flame retardant property that the preparation method obtains is high, it is permanent to have, and be able to maintain the original structure of natural feather and
The characteristic of itself.Preparation method process conditions, the operating method are very simple, it is easy to accomplish produce in enormous quantities.
The technical solution that the present invention solves the technical problem is to design a kind of fire-retardant down fiber and preparation method thereof,
It is characterized in that operating procedure is as follows: (1) weighing a certain amount of down fiber and a certain amount of distillation water logging is added at room temperature
Profit；(2) weigh reaction reagent: the concentration of zirconium salt solution is 0.4-5g/L；The concentration of organic acid is 0.1-10g/L；(3) then handle
Reaction reagent is added in the natural feather of infiltration, adjusts bath raio 1: 100-200；(4) above-mentioned reactant is placed in three-necked flask, in perseverance
Stirring 1-7h, temperature are set as 30-100 DEG C in warm water bath；(5) modified natural feather is taken out, is distilled water washing 3-5 times；
(6) modified natural feather is dried in an oven, 40-100 DEG C of temperature, until obtained by drying arrive the fire-retardant down fiber.
The technical solution that the present invention solves the preparation method is to design a kind of fire-retardant down fiber, it is characterised in that is adopted
It is prepared with above-mentioned preparation method, limit oxygen index (LOI) is 28-38, and has certain far-infrared functional.
Compared with prior art, the beneficial effects of the invention are that: the present invention designs the preparation method work of the right fiber of fire-retardant plumage
Skill condition and easy to operate, and the structure of natural feather and the characteristic of itself can be kept, cost is relatively low, used reagent environmental protection,
It is nontoxic, pollution-free；Fire retardant is grafted on natural feather as crosslinking agent by organic acid and achievees the purpose that permanent fire retardant, is expanded
The use scope of down fiber.
Specific embodiment
Explanation is described in detail to the present invention below with reference to specific implementation case.
A kind of fire-retardant down fiber and preparation method thereof that the present invention designs, it is characterised in that operating procedure is as follows: (1) claim
A certain amount of down fiber is measured, at room temperature, a certain amount of distillation water infiltration is added；(2) reaction reagent is weighed: zirconium salt solution
Concentration is 0.4-5g/L；The concentration of organic acid is 0.1-10g/L；(3) then reaction reagent is added in the natural feather of infiltration, is adjusted
Bath raio 1: 100-200；(4) above-mentioned reactant is placed in three-necked flask, the Stirring 1-7h in thermostat water bath, temperature is set
