Specific embodiment
<The manufacture method of nylon66 fiber doughnut>
Refer to Fig. 1, it is the manufacture method of the nylon66 fiber doughnut according to an embodiment of the present invention
Flow chart of steps.In Fig. 1, the manufacture method of nylon66 fiber doughnut comprise step 110, step 120,
Step 130, step 140, step 150, step 160, step 170 and step 180.
Step 110 is to provide a plurality of nylon 66 resin granules.The weight average of nylon 66 resin granule divides
Son amount can be 30000 to 50000, molecular weight distributing index (polydispersity index；PDI) can be
1.5～2.5.The sulphuric acid relative viscosity of nylon 66 resin granule can be 3.2 to 3.4, when nylon 66 resin
The sulphuric acid relative viscosity of grain is less than 3.2, and made nylon66 fiber doughnut intensity may be led to too low, when
The sulphuric acid relative viscosity of nylon 66 resin granule is more than 3.4, and spinning liquid may be led to stagnant in spinning liquid pipeline
Stay overlong time and unfavorable spinning.The water content of nylon 66 resin granule can be 500ppm to 2000ppm,
Whereby, the water content of nylon 66 resin granule is moderate, can obtain preferably spinning physical property, and can reduce disconnected
Silk and the probability of nylon66 fiber degraded.
Step 120 is by a melting step, makes nylon 66 resin particle fusion to form a spinning liquid,
Melting step can be carried out with 290 DEG C to 295 DEG C of temperature in extruder.When temperature is less than 290 DEG C,
Extruder electric current becomes big, nylon 66 resin particle fusion effect on driving birds is not good, when temperature is more than 295 DEG C, nylon
66 resin particles are also easy to produce cracking cannot spinning.
Step 130 is by one and tells yarn step, makes spinning liquid spin mouth plate by hollow, to form plural hollow
Spin mouth silk.
Step 140 is by a pump step, is to take away, with air suction mode, the heat energy that hollow spins mouth silk, in making
Empty spinning mouth silk primary solidification, to form plural hollow semi-solid preparation silk.Whereby, hollow can be avoided to spin mouth silk excessive
Swelling, and lead to final finished nylon66 fiber doughnut hollow aperture too small, and can avoid hollow spin mouth
Silk rapidly cools down, and leads to the intensity of final finished nylon66 fiber doughnut to decline to a great extent.
Step 150 is by a cooling step, is the cooling wind providing temperature to be 16 DEG C～22 DEG C, makes hollow
Semi-solid preparation silk cools and solidifies, to form plural number solidification silk.Whereby, cool down the moderate temperature of wind, when temperature is low
In 18 DEG C, be easily caused cooling too soon impact molecule forward arrange, when temperature be higher than 22 DEG C, easily because cooling not
It is difficult drawing-off enough.The wind speed of cooling wind can be 0.55m/s～0.75m/s.
Step 160 is by a boundling and oils step, is that solidification silk boundling is oiled, to form collection synnema,
With regard to oiling as located by prior art for solidification silk, will not be described here.
Step 170 is by a drafting step, is collection synnema to be extended, to form an extension silk.
2 figures that refer to, it is the flow chart of steps of step 170 in Fig. 1, in Fig. 2, step 170
Comprise step 171, step 172, step 173, step 174, step 175 and step 176.
Step 171 is the first drawing-off sub-step, can be with the rotating speed of 580m/min～780m/min in room temperature
Under to collection synnema extended.Step 172 is the second drawing-off sub-step, can be with 615m/min～815
The rotating speed of m/min, 55 DEG C～65 DEG C of temperature are extended to collection synnema.Step 173 is the 3rd drawing-off
Step, can be given to collection synnema with the temperature of the rotating speed of 1700m/min～2300m/min, 130 DEG C～150 DEG C
To extend.Step 174 be the 4th drawing-off sub-step, can with the rotating speed of 2600m/min～3200m/min,
200 DEG C～220 DEG C of temperature is extended to collection synnema.Step 175 is the 5th drawing-off sub-step, can be with 2950
The rotating speed of m/min～3350m/min, 210 DEG C～230 DEG C of temperature are extended to collection synnema.Step 176
For the 6th drawing-off sub-step, can be with the temperature of the rotating speed of 2780m/min～3180m/min, 170 DEG C～190 DEG C
Degree is extended to collection synnema.Extended by the multistage of step 171 to step 176 and can be lifted further finally
The intensity of finished product nylon66 fiber doughnut, and the internal stress of collection synnema can be slowed down by thermal finalization, help
In the hollow rate stablizing final finished nylon66 fiber doughnut.
Refer to Fig. 3, it is the flow chart of steps of the step 170 according to another embodiment of the present invention.Figure
In 3, step 170 comprise step 171a, step 172a, step 173a, step 174a, step 175a,
Step 176a and step 177a.Step 171a is the first drawing-off sub-step, step 173a is led for second
Stretch sub-step, step 174a be the 3rd drawing-off sub-step, step 175a be the 4th drawing-off sub-step, step
176a is the 5th drawing-off sub-step, step 177a is the 6th drawing-off sub-step, with regard to the first drawing-off sub-step
Refer to above to the 6th drawing-off sub-step, will not be described here.The embodiment of Fig. 3 and the enforcement of Fig. 2
Mode is compared, how step 172a, and step 172a oils sub-step for oil tanker, is to collection with an oil tanker group
Synnema oils.Carry out (being in the present embodiment between drawing-off sub-step by the oil tanker sub-step that oils
First, carry out between the second drawing-off sub-step, in other embodiment, can change into and carry out between other drawing-off sub-steps),
The homogeneity oiling can be strengthened, contribute to collecting synnema carrying out the not fragile silk of follow-up drawing-off sub-step, and can
Improve yield.
Please answer with reference to Fig. 1, step 180 is by a crimping procedure, be to be wound in a column by extending silk,
To obtain nylon66 fiber doughnut, crimping procedure can be with the rotating speed of 2800m/min～3200m/min normal
Carry out under temperature.Whereby, nylon66 fiber doughnut can be made to form a spinning cake, be conducive to follow-up packaging, fortune
Send.Additionally, by the cooperation of step 170 and step 180, final finished nylon66 fiber hollow can be given
Physical property needed for fiber, such as intensity or stretch rate etc..
Refer to the manufacture method of the nylon66 fiber doughnut that Fig. 4 is according to a further embodiment of the present invention
Flow chart of steps, is compared with the manufacture method of Fig. 1, Fig. 4 many step 100 and step 105.
Step 100 is by a viscosity set-up procedure, and the sulphuric acid relative viscosity making nylon 66 resin granule is
3.2 to 3.4.When the sulfuric acid phase of the nylon 66 resin granule bought or produce falls in aforementioned model to k value
When enclosing outer, before carrying out step 110, can first carry out step 100, to be lifted in final finished nylon66 fiber
The yield of hollow fiber is with transitivity.
Step 105 is by a moisture set-up procedure, and the water content making nylon 66 resin granule is 500ppm
To 2000ppm.When the nylon 66 resin granule water content bought or produce falls outside aforementioned range,
Step 105 can first be carried out, to lift the yield of final finished nylon66 fiber doughnut with transitivity.
Refer to above with regard to step 110 to step 180, no longer repeated.
