Description
Technical field
The present invention relates to sewing thread production technical field, more particularly to a kind of production technology of the black sewing thread of high intensity.
Background technology
Sewing thread is to be knitted the line needed for clothes product, and sewing thread can be divided into natural fiber sewing thread, synthesis by raw material
Fiber sewing thread and mixing sewing thread three major types.Natural fiber sewing thread is the sewing thread prepared using natural fiber as raw material, its
Water suction, air permeable effect are good, the abundance of raw material, but sewing thread made of natural fiber easily deforms in use,
The trend and tensile strength of sewing thread are influenceed, and the raw material that natural fiber uses extracts, increase spinning cumbersome with processing procedure
The difficulty of technique;The tensile strength of synthetic fibers sewing thread is significantly stronger than natural fiber, and in the production process of sewing thread
It is simple to operate also more traditional natural fiber sewing thread, but the resistance to elevated temperatures of existing synthetic fibers sewing thread is poor, temperature
More than 250 DEG C sewing threads easily break, and difficulty is brought to production;Mixing sewing thread solves lacking for synthetic line non-refractory
Point, but need to carry out the concerned process steps of cored in production process, it is necessary to increase special equipment, increase production cost, and increase
Sewing thread production difficulty, extend the sewing thread production cycle.And the dark sewing thread produced at present, especially black are sewed
The fast colours degree of line is poor, fades in use more serious.Based on this, the present invention proposes a kind of black sewing thread of high intensity
Production technology.
The content of the invention
The invention aims to solve shortcoming present in prior art, and the black sewing thread of a kind of high intensity proposed
Production technology.
A kind of production technology of the black sewing thread of high intensity, comprises the following steps:
S1, coloring polyester fiber solution preparation:Using antimony acetate as catalyst, passed through using terephthalic acid (TPA) and ethylene glycol as raw material
The five direct synthetic polyester fibers of kettle working system, then colouring agent and silicone oil are added into polyester fiber, heating fusing, and mix equal
It is even, coloring polyester fiber solution is produced, it is standby;
S2, auxiliary fiber solution preparation:Polyamide and epoxy resin are respectively placed in dryer and dry water removal, then is turned
Move in slicer and cut into slices, be subsequently placed in melting machine and heat fusing, then keeping temperature adds melt index conditioning agent, chlorination stone
Wax, ultra-violet absorber, colouring agent and silicone oil, it is well mixed to produce auxiliary fiber solution, it is standby;
S3, composite fibre preparation:The S1 coloring polyester fiber solution prepared and S2 the auxiliary fiber solution prepared are placed in mixed
In the different barrels for closing spinning-drawing machine, and it is 2~4 according to coloring polyester fiber solution and auxiliary fiber solution:1~3 ratio is entered
Row blend spinning, then cured, vacuum cooled, produce composite fibre;
It is prepared by S4, finished product:Composite fibre prepared by S3 steps is subjected to dewing and hair shredding, cotton carding and mixing in doubling step produce again
Condensating fiber ripe bar, then fiber ripe bar is immersed in into 30~60min in enhancing liquid, then takes out, drains, then through rove, drawing-off, thin
Yarn and double twisting process, produce the black sewing thread of high intensity.
Preferably, polyamide in the auxiliary fiber solution, epoxy resin, melt index conditioning agent, chlorinated paraffin,
The mass ratio of ultra-violet absorber, colouring agent and silicone oil is 60~86:20~43:0.5~1.5:1~3:0.05~0.15:1~
3:12~18.
Preferably, the enhancing liquid is with 1%~3% molybdenum disulfide, 2%~6% nano silicon, 10%~16% liquid
Body paraffin, the mineral oil of surplus mix.
Preferably, five kettle is one kettle of esterification, is esterified two kettles, the kettle of polycondensation one, the kettle of polycondensation two and the kettle of polycondensation three, esterification one
Kettle, two kettles of esterification, the kettle of polycondensation one, the kettle of polycondensation two and the kettle of polycondensation three are sequentially connected.
Preferably, the colouring agent is high-carbon black pigment.
Preferably, the addition of colouring agent is the 1%~3% of polyester fiber quality in the coloring polyester fiber solution, institute
The addition for stating silicone oil in coloring polyester fiber solution is the 3%~6% of polyester fiber quality.
Preferably, the density of the black sewing thread of the production is 1.13~1.53dtex, and length is 35~41mm.
Production technology proposed by the present invention, it is simple to operate, production cost is low, production process is pollution-free, the black sewing of production
Line mass is stable, and colouring agent is mixed into the initial fiber solution of black sewing thread by the way of original liquid coloring, to improve coloring
The color firmness of agent, and silicone oil is added to improve dispersed homogeneous degree of the colouring agent in fiber solution, and also fiber is with polyester
Fiber and the auxiliary fiber of special preparation are combined, and improve fiber overall tensile strength and resistance to elevated temperatures, make system
Standby black sewing thread can add ultra-violet absorber with resistance to more than 300 DEG C of high temperature in the auxiliary fiber of special preparation, to improve
The anti-uv-ray of black sewing thread, influence of the ultraviolet to black sewing thread color and luster is reduced, and then extend black sewing thread and use the longevity
Life;Blend spinning is carried out again using separately preparing fiber solution in production, can improve spinning efficiency, and it is compound after spinning
Fibre property uniformity, stability is good, is selected when composite fibre post-processes with molybdenum disulfide, nano silicon, liquid
The enhancing liquid of paraffin and mineral oil composition carries out performance enhancement, can significantly improve the fast colours degree and tension of black sewing thread
Intensity is stretched, and the knotting frequency of black sewing thread can be reduced, improves the service life of black sewing thread.
