Abstract
The invention discloses a production method of flame retardant fibers, which comprises the following steps: A. preparing flame retardant master batch comprising, by mass, 100 parts of carrier resin, 65-75 parts of main flame retardants, 20-40 parts of auxiliary flame retardants, and 3-5 parts of other auxiliary agents; B. performing melt blending and granulation of the raw materials in step A by a double screw extruder at 200-240 DEG C to obtain flame retardant master batch; C. mixing the flame retardant master batch obtained in step B with a fiber raw material according to a mass percent of the master batch of 2-10%, mixing by a high speed feed mixer, performing extrusion and wire drawing to obtain the flame retardant fibers. The production method of the colorful flame retardant fibers of the invention is energy-saving, reduces the discharge of waste water, and reaches the effect of energy saving and environmental protection.
Description
Technical field
The present invention relates to a kind of production method of fire resistance fibre.
Background technology
Along with improving constantly with socioeconomic of people's living standard develops rapidly, also more and more higher to the requirement of fiber textile both at home and abroad, for example, to reach certain fire-retardant requirement to requirements such as some carpet fabrics and ornaments.
External from having started very early the flame treatment research of polyster fibre, ripe method mainly comprises three kinds now: the firstth, and fire-retardant slice method, the modification of first PET being cut into slices, produces the PET section with flame retardant effect, and then produce fire resistance fibre, arrange out colorful flame-retardant fiber after dyed; The secondth, finishing method, directly uses common PET fiber, obtains fire resistance fibre by dyeing and increasing flame retardant arrangement; The 3rd is additive process, adds fire retardant by common section, is spun into begin-color flame-proof fiber, and the arrangement of then dyeing obtains having the fiber of flame retardant effect.
Above-mentioned three kinds of methods respectively have pluses and minuses, fire-retardant slice method is applicable to the production in enormous quantities of single variety, finishing method and additive process, though flexible and changeable, but three kinds of methods, all need printing and dyeing to arrange an operation, consume mass energy, and can produce a large amount of waste water, and through dyeing and after arrange after flame retardant effect can be uncontrollable.
Therefore, according to potential market demand, study for many years through inventor, developed a kind of new method, can save dyeing and the finishing process of fiber, save mass energy.
Summary of the invention
For solving the problems of the technologies described above, the present invention proposes a kind of production method of colorful flame-retardant fiber, save the energy, reduce wastewater displacement, reach the effect of energy-conserving and environment-protective.
For achieving the above object, technical scheme of the present invention is as follows:
A production method for fire resistance fibre, it comprises the steps:
A, self-control fire-retardant master granule, fire-retardant master granule by mass fraction proportioning is:
100 parts of vector resins;
Main flame retardant 65-75 part;
Auxiliary fire retardant 20-40 part;
Other auxiliary agent 3-5 part;
B, by steps A raw material double screw extruder, under 200-240 ℃ of condition, melting mixing granulation obtains fire-retardant master granule;
C, the fire-retardant master granule that step B is made mix with fibrous raw material mutually by 2-10%, mix by high speed mixer, extrude wire drawing, obtain fire resistance fibre.
According to the present invention, preferred described main flame retardant is TDE.
According to the present invention, preferably described auxiliary fire retardant is antimonous oxide.
According to the present invention, preferably described other auxiliary agent is calcium stearate.
According to the present invention, preferred described vector resin be propylene fine-butylene-styrene resin, chlorinated polyethylene resin or ethene-vinyl acetate copolymer resins.
According to the present invention, in preferred described step C extruded velocity be 55 points/turn, extruder temperature is 230-240 ℃, spin manifold temperature is 200-225 degree Celsius, lateral blowing wind speed 0.4m/s, draw ratio is 2.8-3.6, spinning speed is 400-1000m/min.
By technique scheme, the present invention first prepares fire-retardant master granule, successively mixes mutually with fibrous raw material to be made by fire-retardant master granule, prepare fire resistance fibre, the method has been saved dyeing and the finishing process of fiber, saves mass energy, reduce wastewater displacement, reach the effect of energy-conserving and environment-protective.
The specific embodiment
The production method that the invention provides a kind of fire resistance fibre, it comprises the steps:
A, self-control fire-retardant master granule, fire-retardant master granule by mass fraction proportioning is:
100 parts of vector resins;
Main flame retardant 65-75 part;
Auxiliary fire retardant 20-40 part;
Other auxiliary agent 3-5 part;
B, by steps A raw material double screw extruder, under 200-240 ℃ of condition, melting mixing granulation obtains fire-retardant master granule;
C, the fire-retardant master granule that step B is made mix with fibrous raw material mutually by 2-10%, mix by high speed mixer, extrude wire drawing, obtain fire resistance fibre.
Below by a specific embodiment, the production method of a kind of fire resistance fibre provided by the invention is described:
A, self-control fire-retardant master granule, in the present invention vector resin adopt propylene fine-butylene-styrene resin, get 100 parts, main flame retardant selects TDE to get 60 parts, and auxiliary fire retardant selects antimonous oxide to get 35 parts, and selection of auxiliary calcium stearate is got, its proportioning be propylene fine-100 parts, butylene-styrene tree, 60 parts of TDEs, antimonous oxide is got 35 parts, and calcium stearate is got 5 parts;
B, by the batch mixing double screw extruder in steps A, extruding pelletization goes out fire-retardant master granule.Wherein, the each processing temperature in screw rod district is set to respectively: a district temperature 200-210 ℃, two district temperature 220-240 ℃, three district temperature 220-240 ℃, four district temperature 220-240 ℃, five district temperature 220-240 ℃, six district temperature 220-240 ℃, seven district temperature 220-240 ℃, eight district temperature 220-240 ℃, die head temperature 200-22-℃, time of staying 1-2min, pressure position 10-16Mpa;
