Description
Technical field
The invention belongs to the fiber production technical field, the full drawing-off of the gorgeous ribbon special polyester of particularly a kind of PET superbright mixes the preparation method of fine long filament.
Background technology
It is last word in the market that the full drawing-off of the gorgeous ribbon special polyester of PET superbright mixes fine long filament, on ribbon silk market, belong to high-end product, but there is following defective in it: 1) its brightness and pliability are difficult to take into account simultaneously, high its pliability of long filament of brightness is not enough, and its brightness of long filament that pliability is good is darker; 2) elongation at break is low, and feel is not good.
Summary of the invention
The object of the present invention is to provide the full drawing-off of the gorgeous ribbon special polyester of a kind of PET superbright to mix the preparation method of fine long filament.
Realize that the technology of the present invention solution is: the full drawing-off of the gorgeous ribbon special polyester of a kind of PET superbright mixes the preparation method of fine long filament, may further comprise the steps:
Step 1, material is carried out pre-crystallization, described material PET section; The concrete heated drying air that adopts is carried out pre-crystallization;
Step 2, the feeding of material screw; The PET section that drying is good is sent in the screw extruder with electric and magnetic oscillation;
Step 3, filtration are filtered the fused mass after the extruder extruding, guarantee the constant of continuous production spinning and screw extruder pressure when filtering;
Step 4, spinning, fused mass after coming out from filter enters spinning manifold, spray from mixing spinneret hole by spinning manifold, carry out drawing-off, typing, coiling and molding afterwards, wherein said spinnerets is provided with the spinneret orifice that is shaped as triangle, circle, and the preceding strand of reeling is introduced into the dual network nozzle and adds network.
The quantitative proportion of described triangle spinneret orifice and circular spinneret orifice is 8-30: 1.
When step 1 was carried out pre-crystallization with material, the temperature of pre-crystallization was 168～178 ℃, and the temperature of heated drying air is 170～178 ℃, and air dew point is smaller or equal to-60 ℃, and material moisture is 30ppm, and be 5～8 hours drying time.
The screen pack that filters filter device therefor when step 3 is filtered is 25 microns.
The spinneret orifice that step 4 is sprayed silk is special-shaped spinneret orifice of three unique leaves and round spinneret orifice mixed type spinnerets, described filament spinning component is 30/120/150/400/250/400 purpose screen pack, temperature during spinning is 288～298 ℃, spinning speed is 4300～4500 meters/minute, the wind speed of cooling quench is 0.4～0.6m/s, wind-warm syndrome is 23～25 ℃, and relative humidity is 70～80%.
Spinning manifold in the step 4 adopts the slow cooling heater.
According to technique scheme, product of the present invention has the following advantages:
1) color and luster brilliance is gorgeous: this project adopts the spinning manifold that has the slow cooling heating, special-shaped spinneret orifice shape spinnerets of three unique leaves and circular hole production, and finished product strand cross sectional shape major part is an equilateral triangle, and brightness is higher, and dyeing back bright in color is gorgeous.
2) soft exquisiteness: most of fibre section is an equilateral triangle in this combined yarn, and the sub-fraction fibre section is circular, soft, fine and smooth, smooth.
3) elongation at break is higher: when we develop this product, adopted comparatively advanced equipment having the spinning manifold production of slow cooling heater, take unique process for high speed spin-drawing one-step method to finish, has higher elongation at break, its elongation at break reaches 36% ± 2, and common long filament only is 26% ± 4
Exempt from starching when 4) weaving: adopt during production to add pre-network and then drawing-off and HEAT SETTING earlier, strand enters the dual network nozzle and adds network before coiling, and the network degree is more, reaches 16-20/m, conventional long filament only be 8-12 individual/m.
The present invention compared with prior art, the mixed fine long filament of being made by PET of the full drawing-off of the gorgeous ribbon special polyester of superbright has some total character of polyester fiber, but the excellent ribbon silk of making at PET is simpler than the production of polyamide fibre ribbon silk, cost of material is lower, the finished silk price is low, performance is similar to polyamide fibre, after spinning through drawing-off, HEAT SETTING, add network one step and finish, make the fiber made not only have bright color but also have the feel of soft and smooth property.Concrete advantage is as follows: the silk brightness of 1) spinning is higher, and dyeing back bright in color is gorgeous, plays fabulous decoration function when making gift wrap; 2) fiber and goods thereof is soft, because elongation is bigger, soft comfortable when making product; 3) have good dyeability, can be used for common DISPERSE DYES and carry out boiling dyeing at normal pressure and need not carrier, dye to such an extent that fiber COLOR FASTNESS and oxygen resistence are strong; 4) have good chemical proofing, light resistance and heat resistance; 5) fiber never fades.
