In addition, the production method of the heavy denier polyester fiber is simple, has strong operability and can also meet the requirement of further processing.
Description
Technical field:
The present invention relates to a kind of heavy denier polyester fiber and production method thereof.
Background technology:
Polyester fiber has the intensity height, good springiness, and wrinkle resistance is strong, and the good and cost of dyeing is lower and be widely used in synthetic fiber.But for some polyester fiber, we have the above-mentioned multinomial advantage except wanting it, also will allow the fabric that it was made into have gas permeability preferably, and the feel of refrigerant and imitative fiber crops also will make fabric have characteristics such as hale and hearty style simultaneously.In order to obtain above characteristics, can set about Here it is said coarse denier fiber or have the coarse denier fiber of odd-shaped cross section by the cross sectional shape aspect that increases filament number and change monofilament.
In technical literature and related data, dividing for the filament number of coarse denier fiber is not very clear and definite.The criteria for classification that is proposed according to AKZO company is when filament number is a coarse denier fiber during greater than 7.0dtex.Though the production of coarse denier fiber still is in the starting stage, along with the expansion gradually of the market demand, the potential of heavy denier yarn will be excavated more fully.In recent years, the kind of the heavy denier polyester fiber of domestic-developed is in the majority with circular cross-section, and odd-shaped cross section is less.
When utilizing conventional melt spinning method to produce heavy denier yarn, raw material and spinning technique must strictly be controlled, just can obtain the heavy denier yarn of excellent performance.
The object of the present invention is to provide a kind of monofilament is thick dawn, performance good heavy denier polyester fiber and production method thereof.
Technical solution of the present invention is:
A kind of heavy denier polyester fiber is characterized in that: filament number is 7～20dtex, and the monofilament sum of fiber is greater than 1.
When fiber cross section is a triangle during to the bihexagonal odd-shaped cross section, the gloss of fiber is better, and the refrigerant sense of fabric is better.The degree of profile scope of profiled filament is 1.25～3.5.Filament number is taken all factors into consideration from the style of fabric and the stability of spinning, and best filament number is 10～15dtex.
The raw material polyester slice comprises: ethylene glycol terephthalate, propylene glycol ester terephthalate, mutual-phenenyl two acid bromide two alcohol ester and above three kinds modified poly ester thereof.
The production method of heavy denier polyester fiber of the present invention, it is characterized in that: earlier with polyester slice drying, dried section process screw extruder melt extruded, extruder is provided with the multistage thermal treatment zone, the heating-up temperature in each district is located between 260～290 ℃, polymer after the fusion flows in the spinning manifold, and spinning body temperature is located at 260～290 ℃.Extrude setting, lateral blowing cooling curing by circle or profile spinneret then, give oil processing through oil nozzle or oiling roller again, the extension, the nozzle of interlace that reach between 1 roller and 2 rollers add interlacing, and reeling by coiler device at last formalizes, and gets heavy denier polyester fiber.Coarse denier fiber of the present invention is because monofilament is thicker, and three part particular importances of moulding are controlled and batched to lateral blowing cooling and shaping, oil supply in spinning process.The oil supply mode preferably adopts the oiling roller oil supply, and the oil supply position generally is not less than 5000mm.Preorientation fibre single thread fiber number is when 25dtex is following, also can take oil nozzle oil supply mode, this moment, the oil supply position should be not less than 1500mm, cooling uses wind-warm syndrome below 25 degree, best wind-warm syndrome scope is 15 degree～20 degree, wind speed is in 25m/min～60m/min, and best wind speed range is 30m/min～45m/min.
Heavy denier yarn of the present invention can utilize spinneretss such as circle or abnormity (as triangle～12 jiao etc.) to carry out spinning.
When producing preorientation polyester fiber (POY), the speed of 1 roller is 2500～3500m/min, and the speed of 2 rollers is 2500～3500m/min, and the coiling speed of spinning is 2500～3500m/min; When producing high oriented polyester fiber (FDY), the speed of 1 roller is 1500～3000m/min, and the speed of 2 rollers is 3500～5500m/min, and the heat roller temperature of 1 roller is 70 ℃～120 ℃, and the heat roller temperature of 2 rollers is 100 ℃～180 ℃.
The preorientation heavy denier polyester fiber is being carried out can get false-twist textured yarn or low-stretch yarn after processing is extended in false twisting, processing conditions is: the temperature range of 1 hot plate is 140 ℃～190 ℃, and the temperature range of 2 hot plates is normal temperature～180 ℃, and the scope of extension ratio is 1.4～2.5.
Coarse denier fiber of the present invention has better spinnability energy and processability; Heavy denier yarn function admirable of the present invention is stable, and imitative fiber crops are effective, and gas permeability is stronger, and feel is refrigerant, dry and comfortable, and reflecting feel is strong, and the bounce-back recovery is good, has good taking.In addition, production method technological process of the present invention is short, and manufacturing procedure is few, and production cost is low, easy operating.
The assay method of triangle～12 angular cross section shape degree of profiles is: the fibre section is amplified to suitable multiplying power at microscopically, print after taking photo, measure the circumscribed circle diameter R1 and the inscribed circle diameter R2 of fibre section, degree of profile M value is exactly R1/R2, usually measure 5 groups of monofilament, average then.
The invention will be further described below in conjunction with drawings and Examples.
