And its production method, the intensity of Fypro seam envelope curve is promoted, avoids occurring pulling apart phenomenon in seam packet procedures, guarantees seam packet
Process is gone on smoothly.
To realize above-mentioned technical purpose and the technique effect, the present invention is achieved through the following technical solutions:
A kind of Fypro seam envelope curve, including nylon 6, plasticiser, fire retardant and mica master batch, 6 percentage of nylon
Score is 80% ~ 90%, and the plasticiser fractions are 6% ~ 8%, and the fire retardant fractions are 2% ~ 14%, remaining is
Mica master batch.
Preferably, in above-mentioned Fypro seam envelope curve, the plasticiser includes caprolactam monomer, halogenation iodine and road
Lewis acid.
Preferably, it in above-mentioned Fypro seam envelope curve, the caprolactam monomer, halogenation iodine and lewis acidic accounts for
Than for 8:1:2.
Preferably, in above-mentioned Fypro seam envelope curve, the plasticiser further includes potassium halide, and the potassium halide percentage
Number accounting is equal with the halogenation iodine percentage accounting.
Preferably, in above-mentioned Fypro seam envelope curve, the fire retardant uses halogen compounds.
Preferably, in above-mentioned Fypro seam envelope curve, the halogen compounds is bromine based compound.
A kind of Fypro seam envelope curve production method, includes the following steps:
S100, master batch are blended: mica master batch be dried in vacuo, drying temperature is 105 ~ 125 DEG C, and drying time is 2 hours,
And it is proportionally blended with nylon 6 slice；
S200, extrusion molten: plasticiser and fire retardant ratio are added in the melt of nylon 6, and squeeze molten
Melt；
S300, filtering residue: the blend after melting is filtered, the non-fusant matter in blend is removed；
S400, metering spinning: the spinning of blend is carried out according to the specification of production requirement, and is blowed under oxygen-free environment cold
But；
S500, drawing-off winding: hot gas spring is carried out to spinning after molding and is wound collection, obtains target spinning.
The beneficial effects of the present invention are:
The present invention has rational design, is modified by the adjustment to plasticiser ingredient to Fypro, by changing polyamides
In amine fiber the quantity of hydrogen bond come promoted Fypro seam envelope curve degree of drawing and intensity, substantially increase Fypro
The quality of production for stitching envelope curve, efficiently solving seam envelope curve, there is a phenomenon where pull apart in use.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
Detailed description of the invention
In order to illustrate the technical solution of the embodiments of the present invention more clearly, will be described below to embodiment required
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for ability
For the those of ordinary skill of domain, without creative efforts, it can also be obtained according to these attached drawings other attached
Figure.
Fig. 1 is the production method flow chart that Fypro of the present invention stitches envelope curve.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all other
Embodiment shall fall within the protection scope of the present invention.
Refering to Figure 1, the present embodiment is that a kind of Fypro stitches envelope curve, including nylon 6, plasticiser, fire retardant
And mica master batch, 6 fractions of nylon are 80% ~ 90%, plasticiser fractions are 6% ~ 8%, fire retardant percentage score
Number is 2% ~ 14%, remaining is mica master batch, and plasticiser includes caprolactam monomer, halogenation iodine and lewis acid, caprolactam
Monomer, halogenation iodine and lewis acidic accounting are 8:1:2, and plasticiser main function is to weaken polyamide molecule interchain hydrogen bond to make
With maintaining a certain distance molecule interchain, to reduce the formation of hydrogen bond, so that the relative motion between polymer molecule be made to become
It is easy, polymer melt fusing point reduces, and becomes easy to the stretching of as-spun fibre, and can produce super drawing, so that height be made
Strong fiber.Plasticiser further includes potassium halide, and potassium halide percentage accounting is equal with halogenation iodine percentage accounting, due to metal from
Son has higher charge and coordination ability, and after metal salt is added in polyamide, fusing point is reduced, and machine-shaping becomes different, and dissolves
Performance also makes moderate progress, during stretching, the declines of molecule interchain hydrogen bond, cohesive energy reduce, by super drawing with
Expected orientation is obtained, the formation for restoring its hydrogen bond then is complexed to solve, and then improve fusing point and tensile strength, obtains high power drawing
The high-strength Fypro of multiple is stretched, fire retardant uses halogen compounds, and halogen compounds is bromine based compound, halogen compounds
The heated reaction of decomposing of fire is met, the halide ion decomposited is reacted with high-molecular compound generates hydrogen halides.The latter and high score
The active hydroxyl groups radical reaction being largely proliferated in sub- compound combustion process makes the reduction of its concentration, and burning velocity slows down, until
Fray-out of flame.In halogen, the fire retardation of bromine is bigger than chlorine.
The present invention also provides a kind of Fypros to stitch envelope curve production method, includes the following steps:
S100, master batch are blended: mica master batch be dried in vacuo, drying temperature is 105 ~ 125 DEG C, and drying time is 2 hours,
And it is proportionally blended with nylon 6 slice；
S200, extrusion molten: plasticiser and fire retardant ratio are added in the melt of nylon 6, and squeeze molten
Melt；
S300, filtering residue: the blend after melting is filtered, the non-fusant matter in blend is removed；
S400, metering spinning: the spinning of blend is carried out according to the specification of production requirement, and is blowed under oxygen-free environment cold
But；
S500, drawing-off winding: hot gas spring is carried out to spinning after molding and is wound collection, obtains target spinning.
The present invention has rational design, is modified by the adjustment to plasticiser ingredient to Fypro, passes through change
In Fypro the quantity of hydrogen bond come promoted Fypro seam envelope curve degree of drawing and intensity, substantially increase polyamide
Fiber stitches the quality of production of envelope curve, and efficiently solving seam envelope curve, there is a phenomenon where pull apart in use.
