Description
Technical field
The present invention relates to a kind of production technologies of fiber, more particularly, to a kind of production work of ultra-fine soft suede fluffy fiber
Skill.
Background technology
Social economy of the country grows rapidly at present, and science and technology is advanced by leaps and bounds, and fiber product type is maked rapid progress, to chemical fibre
The Functional Requirement of the fabric of product is also higher and higher, and industry competition is more and more fierce, and exploitation adapts to the high new varieties of new era,
Enterprise product it is differential, be the maximum task that current company faces.It develops with high added value, mark is new in the industry
Start something different, the fibre in differentiation Cai Nengshi enterprises taken the course of its own are based on market.Heng Teng companies are with advanced production equipment and maturation
Production technology be item base, by unremitting effort, developed on veneer list cake ultra-fine soft suede fluffy fiber have it is only
The brand product of characteristic energy,
Ultra-fine soft suede fluffy fiber is mainly used for high-grade sanding cloth fabric, knitting fabric and high-density fabric etc. fields.With it is similar
Product is compared, and the product filament number is superfine, and monfil hole count is more, and the stability requirement of product interior quality is high.
Relative to the product of other productions of company, the porous fine denier fiber product, filament number is thin, and contact surface area is big,
Therefore institute's woven fabric has good flexibility and hydroscopic fast-drying effect.The done soft velvet of fabric is strong, lofting effect is prominent, color and luster temperature
Profit, sense of touch are careful, and moisture absorption is ventilative, is mainly used in high-grade women's dress, easy dress, jacket housing etc..
But produce in the technique of the production of ultra-fine soft suede fluffy fiber that often there is due to spinneret face temperature at present
Degree not enough causes cold plate phenomenon, leads to production broken end rouleau drop etc. and also has tow to jump out oil nozzle or a phenomenon of floaing, cause
Tow oils irregular problem.
Invention content
The present invention be in order to overcome in the prior art spinneret face temperature not enough cause cold plate phenomenon, tow to oil not
Even, product item is done and the unstable problem of intensity, and providing one kind can prevent spinneret face temperature inadequate, and tow oils
It is even, the dry production technology with a kind of ultra-fine soft suede fluffy fiber of intensity stabilization of product item.
To achieve the goals above, the present invention uses following technical scheme：
A kind of production technology of ultra-fine soft suede fluffy fiber, the production technology includes following steps：Polyester fondant →
Pipeline → booster pump → melt cooler → static mixer → melt distributing valve → spinning manifold → metering pump → spinning
Component → spinneret → ring Blowing drum cooling → oil nozzle oils → and path → pre- network → GR1GR2 godets → coiling and molding → fall
Barrier packaging；Wherein ranging from 283~287 DEG C of melt pipe heat medium temperature；290-300 DEG C of the spinning body temperature；Institute
The size for the ring Blowing drum middle ring blowing air pressure stated is 20-30 Pa, and wind-warm syndrome is 18.5-21.5 DEG C, and wind moisture is 80-88 %；Institute
The pre- network pressure stated is 0.05 Mpa；Oil nozzle oiling method is that four layers of oil groove oil nozzle oil；Spinning speed is 2600-2680
M/min, GR1/GR2 speed are respectively 2620-2680 m/min and 2640-2680 m/min.
Melt conveying temperature there is large effect can make to melt if melt conveying temperature is too low the production of fiber
Liquid flowability is deteriorated, and can influence the uniformity of polyester quality, and the abnormalities such as broken end are caused in spinning, and works as melt
Thermal degradation, which can occur, for melt when the temperature is excessively high causes polyester viscosity to decline, and content of carboxyl end group increases, and gel particles is generated, when serious
Polyester color and luster turns to be yellow, and seriously affects normal spinning production.Thus, when selecting melt conveying temperature, to ensure having good stream
Viscosity drop is as minimum as possible while denaturation.With reference to having fine-denier variety production process conditions and knowhow, by melt conveying
Line temperature range is scheduled on 283~287 DEG C.
The ultra-fine soft suede fluffy fiber kind monofilament linear densities of 278dtex/350F POY are small, large specific surface area, tow radical
It is more, cooling such as is blown using side-blown, it is difficult to tow cooling is uniform, and strand shake is big, and tow yarn unevenness can be caused to rise,
Broken end increases, therefore the method that the present invention uses ring wind quenching, and when wind pressure is smaller, cooling air quantity is inadequate, can not uniformly fully
Cooling tow so that the yarn unevenness and broken end number of tow increase；When wind pressure control is excessive, tow cooling is very fast, coagulates
Solid point moves up, and tow concussion aggravation, the air-flow of turbulence, which travels to stretcher strain area, to cause spinneret face to cool down, and broken end increases
Add, yarn unevenness rises, and considers, and wind pressure control is in 20-30 Pa, and wind-warm syndrome is 18.5-21.5 DEG C, wind moisture 80-88
% or so is advisable.
Since this product hole count is more, by the traditional U-shaped or V-type oil nozzle of test of many times in the case where oil pump capacity is certain,
Lamination is easy when oiling, it is difficult to ensure that the uniformity that tow oils, and when wide oil nozzle of traditional flat mouth oils is easy oil spout.It is existing
Company is oiled using four layers of oil groove oil nozzle, unique spin finishing system design, in the case where oil pump capacity is certain, it is ensured that on
The uniformity of oil, solves oil nozzle oil spout, oil irregular phenomenon, improves the inherent quality of product.
Preferably, the specification of the ultra-fine soft suede fluffy fiber is the ultra-fine soft fluffy fibres of suede of 278dtex/350F POY
Dimension.
Preferably, the polyester fondant be polyethylene terephthalate melt, inherent viscosity be 0.633 ~
0.657 dl/g, content of carboxyl end group are 27 ~ 33 mol/t, and diethylene glycol content is less than or equal to 1.20 %, and content of titanium dioxide is
0.27~0.33 %。
Preferably, the finish that the oil nozzle uses when oiling is SS companies of Germany L-165POY finishes, effective concentration
More than 90%.This finish can increase the cohesive force of tow, reduce the electrostatic that friction generates, in pervious Fine-denier flat yarn
Application effect is preferable in production.
Preferably, gather position is 1000mm when the boundling oils.
Preferably, the spinneret is equipped with the spinneret orifice being arranged in a manner of concentric arrays on spinneret, spray
The quantity of wire hole is 350.Spinneret spinneret orifice again R ＆ D design is arranged, goes out wire hole range shorter by original, and
Corresponding component sand cup cavity filter area reduces, and efficiently solves the plate face heat of the spinneret when producing fine denier polyester POY
Off-capacity, it is ensured that in the case where melt discharge is few, ensure spinneret face temperature.
Therefore, the present invention has the advantages that：（1）It can effectively prevent preventing spinneret face temperature inadequate；（2）
Tow oils uniformly；（3）Product item is done and intensity stabilization.
Specific implementation mode
Below by specific implementation mode, the present invention will be further described.
