Team's discovery of the present invention, in order to further increase the comprehensive performance of yarn, it is also necessary to the spinning in same combination
Line optimizes matched combined, may after the individual performance and combination for needing to comprehensively consider each spinning threadling with clock synchronization
The effect that can be showed.After team of the present invention attempts on the basis of theory using a large number of experiments, above-mentioned three kinds of cooperations are found
Spinning threadling it is compound after yarn resultant effect it is best.Obtaining said combination needs this foundation in team of the present invention experience abundant
On, not simple assembled arrangement can obtain.
A kind of preparation method of terylene Multi-functional fancy yarn line, comprising the following steps:
1) cation MOY are fed by zero roller, intermittent to heat by hot-rolling under the reciprocally swinging effect of swing rod, so
Enter a roller afterwards.
In step 1), cationic MOY under the action of swing rod, it is intermittent by hot-rolling heat, in this section master
If drafting forming, wherein be by the effect of swing rod effect: 1, cationic MOY can be made to have part after finally compound
Strand is wound on outside tow；2, the heating of strand intermittence (is heated, when strand is detached from hot-rolling when strand touches hot-rolling
It does not heat, while swing rod, during swinging back and forth, tension also can be different, therefore are equivalent to and carry out space drawing to strand,
Strand internal crystallization orientation generates variation), the strand obtained using this processing method can be by one since drawing-off degree is different
Kind strand takes on the double-colored special decorative pattern of the depth, while in final gained yarn, winding effect of the MOY on FDY is presented
For a Duan Miyi sections of thin compartment distribution).
2) while two kinds fine-denier porous fire-retardant POY first carries out pre- network, enters sieve after the feeding of another zero roller of road
It draws.
3) cation MOY, fine-denier porous fire-retardant POY and full-dull FDY converge at a roller；Then it successively passes through
Drawing-off, deformation, cooling, false twisting, network is compound, is formed, obtains terylene Multi-functional fancy yarn line after winding.
In step 3), three kinds of spinning threadlings realizations are compound, obtain finished product.
Preferably, deformation temperature is 200-220 DEG C.
Preferably, setting temperature is 180-200 DEG C.
Preferably, draw ratio DR of cation MOY between zero roller and a roller01For 1.55-1.65；Fine-denier is more
Draw ratio DR of fire-retardant POY of the hole between zero roller and a roller02It is 1.05-1.1 for 0.98-1.0, dominant draft DR.
In order to make yarn that better effect be presented, considered critical draw ratio is needed, under above-mentioned draw ratio, POY are in
Overfeeding relaxed state, therefore in final gained yarn, POY are to float on yam surface, and the POY due to using is porous knot
Structure, therefore lofting effect is played, there is the feel similar to villus.Simultaneously as POY of the present invention or fire-retardant silk, therefore rise
To flame retardant effect.As common knowledge, burning is all from outward appearance to inner essence that POY when of the invention with flame retardant effect floats on yarn
Best flame retardant effect is played on surface, hence for the then outstanding flame retardant property of need not have of the FDY as trunk.
Preferably, process velocity is 300-400m/min.
Preferably, in order to further increase the quality of yarn, present invention defines the original of each raw material thread, the fine-denier
It is that raw material is spun after twin-screw extrusion that porous fire-retardant POY, cation MOY and full-dull FDY, which are all made of polyester slice,
Silk is made, and the preparation method of the polyester slice has following two:
The first: carrying out esterification for terephthalic acid (TPA), ethylene glycol, pressure is no more than 0.3MPa, instead at 230~260 DEG C
1~3h is answered, prepolymer is obtained；Then polycondensation reaction is carried out under vacuum conditions, and reaction temperature is 270~290 DEG C, and pressure is lower than
100Pa reacts 1~4h, and modified poly ester is made；Polyester slice is made after dry, slice；Catalyst is urged using silicon titanium composite homogeneous
Agent, catalyst are added before or after esterification, and dosage is calculated as 0.5~10ppm with polyester；
Second: being beaten, be successively esterified, precondensation and final polycondensation reaction using terephthalic acid (TPA), ethylene glycol as raw material；
Wherein, at 220 ~ 270 DEG C, pressure is normal pressure ~ 0.5MPa, 1.5 ~ 5.5h of time for esterification reaction temperature control；Prepolymerization reaction temperature
At 240 ~ 270 DEG C, pressure is 1 ~ 101KPa, 0.5 ~ 2.5h of time for degree control；Final polycondensation reaction temperature is controlled at 270 ~ 300 DEG C,
Pressure is 30 ~ 300Pa, 1 ~ 3.5h of time, and polyester is made；Polyester slice is made after dry, slice；Catalyst is poly- using environment-friendly type
Ester titanium complex catalyst, catalyst are added before esterification or after esterification；Yield based on polyester, is calculated with titanium elements, is urged
The addition quality of agent is 2 ~ 50ppm.
Application of the above-mentioned terylene Multi-functional fancy yarn line on carpet, curtain and decorative textile product.
It is compared with the prior art, the beneficial effects of the present invention are:
Of the present invention is a kind of preparation method of terylene Multi-functional fancy yarn line, and the product of this method preparation has good
Flame retardant property, comfortable feel, well arranged, three-dimensional sense is strong, style varied, and compared with prior art, this method solve biographies
System product comfort is poor, style color, has a single function, and is post-processed by dyeing and finishing, fabric color multiplicity, and product shading performance is excellent
Different, stereovision is strong, is primarily adapted for use in the fields such as carpet, curtain, bunting, especially rather well received in window screening field, has good
Good anti-perspective and flame retardant effect.

The preparation of environment-friendly type polyester titanium complex catalyst: cetane trimethyl ammonium bromide and neopelex are pressed
It is dissolved in the deionized water of 1000ml according to molar ratio 4:1, is configured to the solution that total concentration is 0.03mol/L, ultrasonic 0.5h
After stand for 24 hours.Then ammonium hydroxide 10ml, ethyl alcohol 250ml, ether 250ml is added, the positive silicic acid second of 30g is added after being vigorously stirred 0.5h
Ester continues to stir 4h completion reaction.Reaction solution is filtered, and filter cake washs 5 bakings for being placed on 60 DEG C with second alcohol and water repeatedly
12h is dried in case, then place the product in 550 DEG C of Muffle kiln roasting 3h, and it is micro- that mesoporous silicon dioxide nano is made after crushing
Ball.Then ethylene glycol, magnesium acetate, titanium tetrachloride are added sequentially in three-necked flask, addition molar ratio be 20:4:1, then plus
Entering mesoporous silicon dioxide nano microballoon, the mass ratio with titanium tetrachloride is 5:1, under the protective effect of nitrogen, ultrasonic reaction 4h,
Reaction temperature controls 160 DEG C, speed of agitator 120r/min.Reaction terminates to stand is obtained by filtration solid afterwards for 24 hours, with ethyl alcohol and goes
Ionized water 3 environment-friendly type polyester titanium complex catalysts obtained by drying of a washing repeatedly.
The preparation of polyester slice: by 1.86kg ethylene glycol, 16.6kg p-phthalic acid and environment-friendly type polyester titanium system
Composite catalyst (quality of titanium atom is 5ppm, is calculated with the theoretical yield of polyester), which is added in the reaction kettle of 2L, to be beaten
Slurry.Esterification temperature is controlled at 240 DEG C, pressure 0.3MPa, time 2.5h, esterification yield 93%；Esterification terminates that delustering agent titanium dioxide is added
Titanium, additive amount are that 0.25%(is calculated with the theoretical yield of polyester)；Precondensation controls 260 DEG C of temperature, reaction pressure 50KPa；Final minification
Gather controlled at 280 DEG C, pressure 50Pa, the polycondensation time, 2.5h obtained polyester.Obtained polyester slice after dry sliced.
