Description
Technical field
The present invention relates to the phosphorus flame retardant is bamboo pulp flame-retardant fiber of Additive Production and preparation method thereof, more precisely, is that phosphorus flame retardant and bamboo pulp fiber raw material are obtained the suitability for industrialized production bamboo pulp flame-retardant fiber through certain production technology.
Background technology
Bamboo pulp fiber is to be raw material with the bamboo wood, through being processed into bamboo pulp, makes through cellulose viscose manufacturing technique processing more afterwards.Bamboo pulp fiber also has excellent antibacterial bacteriostatic function when having the viscose characteristic, make bamboo pulp fiber become a kind of textile material of function admirable.But along with the consumption figure of various textiless increases day by day, the fire that is caused by textiles also constantly increases.Developed countries such as America and Europe, Japan have proposed requirement to the anti-flammability of textiles, and have formulated each class standard, limit non-flame-retardant textile from the kind and the applicable situation of textiles, and the application of bamboo fibre and goods thereof and outlet are affected.
The manufacture method of fire resistance fibre mainly comprises two kinds, and a kind of is coating, and promptly the fire retardant among the post-processing stages of fiber production will be sneaked into crosslinking agent or adhesive anchors at fiber surface, makes fiber have anti-flammability.Another kind is a blending method, and fire retardant is added in the spinning solution, makes fire resistance fibre through spinning.The fire resistance fibre that coating is made because fire retardant is coated on fiber surface, make fiber surface harden, coarse, even some fire retardant also can send some nifves, uses anti-flammability to descend for a long time, and the fiber applications field is restricted; The fire resistance fibre that blending method is prepared, fiber has had the change of essence than coating fiber at aspects such as surface state, flexibilities, but shortcomings such as the made fire resistance fibre of this method also exists function singleness, and Application Areas is narrow make the marketing of fire resistance fibre be subjected to serious restriction.
Bamboo pulp is because defectives such as poor, the grey iron content height of reactivity worth if utilize bamboo pulp to produce bamboo pulp flame-retardant fiber, make the fiber production process than other slurry kind of fiber difficulty, and the every index of fiber also decreases than other slurry kind of fiber simultaneously.Utilize bamboo pulp to produce bamboo pulp flame-retardant fiber and yet there are no report in publication and the patent at home.
Summary of the invention
The object of the present invention is to provide a kind of phosphorus flame retardant that utilizes to be bamboo pulp flame-retardant fiber of Additive Production and preparation method thereof,, make viscose glue have strainability and spinning property preferably by to the optimizing and revising of each procedure technology in glue, the spinning.The fiber that spins has fire-retardant preferably, bacteria resistance function, and aspects such as intensity, color and luster have had preferably to be improved.Fiber stands repeatedly to wash, high temperature, chemicals still have after handling stronger functional.
The invention provides a kind of bamboo pulp flame-retardant fiber, its bone dry fiber content is 85-93% weight; Surplus is moisture content and trace impurity.Described impurity is the impurity that resides in the fiber production process in the final products, comprises finish or the like.
Dried fracture strength 〉=the 1.42CN/dtex of this fiber; Wet breaking strength 〉=0.64CN/dtex.
Preferably, fibrously be: bone dry fiber content is 84.7-92.85%; Water content is 7-15%; Oil content is 0.15-0.30%;
In addition, the limited oxygen index of fabric of the present invention 〉=26%; Antibacterial value 〉=2.0, sterilizing value 〉=0.3 (detection) according to JIS.
In addition, the present invention also provides a kind of preparation method of bamboo pulp flame-retardant fiber, comprising: feed intake, flood, squeezing, pulverizing, experienced, yellow, dissolving, mixing, filtration, deaeration, spinning, boundling, cut-out, washing, desulfurization, bleaching, acid activation, step oils, dewaters, dries and pack; Add in the operations such as the yellow of phosphorus flame retardant in the viscose production procedure, dissolving, mixing, spinning.
Wherein phosphorus flame retardant is inorganic or organic phosphorus compound, as one or more mixtures of red phosphorus, Quadrafos, polyphosphate pyrophosphate and melamine phosphate etc.Wherein the average grain diameter of phosphorus flame retardant is less than 5.0 microns.Addition is the 5-45% of the fine amount of relative first, is mixed with the aqueous dispersions of 3-50% in use, and wherein dispersant is anion or nonionic class surfactant, and addition is the 0.5-3.5% of flame retardant amount.
For improving the strainability and the spinning property of viscose glue, each operation in producing to be adjusted, the main technique index is as follows:
Spinning glue index: the fine content 7.5-10.5% of first; Total alkali 4.5-6.5%; Viscosity 20-55 second; Degree of ripeness 8-18ml (10% ammonium chloride value);
Acid bath index: sulfuric acid content 90-140g/l; Zinc sulfate content 5-30g/l; Sodium sulphate content 280-355g/l; Bathe warm 40-65 ℃.
Because the antibacterial substance behind the adding fire retardant in the viscose glue loses activity, and must increase the acid activation process in the post processing of fiber production, and antibacterial value activity is restored, this also is that the present invention is requisite.Acid activation liquid is prepared with organic acid or inorganic acid, and pH value is 2-6.5, and temperature is 20-80 ℃, and the processing time was greater than 10 seconds.
