Description
Technical field
The present invention relates to a kind of melt spinning method, more specifically, it relates to a kind of color composite polyester yarn that produces
Method.
Background technique
White mixed fiber composite dacron thread technology comparative maturity, but two-step process is mostly used to produce, process flow
It is long, production efficiency is low, energy consumption and loss are big, and to make colored fabric, it is also necessary to process textile dyeing after weaving, after this
Continuous deep processing link is seriously polluted, and pole is not environmentally.
Currently, the Chinese patent that notification number is CN102995151A discloses a kind of One-step production color composite polyester yarn
Method, it includes that the polyester chip transportation in chip bunker is dried into chip dryer, is then sent to screw rod
Heating melting is at melt in extruder；Masterbatch in Masterbatch feed bin is sufficiently dry in masterbatch drying machine, passes through small screw
The polyester fondant output channel for entering slice screw extruder after implanter heating melting by metering pump accurate measurement, with polyester
Melt is stirred the evenly dispersed dyeing realized to polyester fondant together, through dynamic mixer；Melt after dyeing enters spinning
Silk cabinet, the spinning manifold are divided into two parts, and a portion spinning station uses the process route of Direct Spinning preoriented yarn, separately
A part of spinning station is equipped with hot-rolling drafting system, using full-drawn yarn process route；Preoriented yarn and full-drawn yarn are by side-blown
Air-cooling device and through finish pump-metered spray oil after, from spinning shaft output be divided into two-way, all the way in preoriented yarn warp
It crosses spinning shaft and godet enters in composite network device, another way full-drawn yarn is after spinning shaft, through pre- network nozzle
Preliminary network enters composite network device and preoriented yarn after being sufficiently tensile under the action of the first draw roll and the second draw roll
Shu Binghe；Preoriented yarn and full-drawn yarn carry out network combined sizing by networking nozzle in composite network device, are formed mixed
Fine composite coloured dacron thread；Mixed fiber composite dacron thread, which enters, to carry out batching molding in up- coiler.
The method of this One-step production color composite polyester yarn is easy to operate, but in actual use, and slice raw material exists
During storage, in air a large amount of dust can be deposited in slice raw material in, and by containing more dust slice raw material into
Row processing will cause the second-rate of the silk thread to be formed.
Summary of the invention
In view of the deficienciess of the prior art, leading to the invention reside in a kind of method for producing color composite polyester yarn is provided
Setting vibrating screen is crossed, dust is sifted out, achievees the purpose that promote silk thread quality.
To achieve the above object, the present invention provides the following technical scheme that a kind of method for producing color composite polyester yarn,
Include the following steps:
Step 1: by slice raw material through traveling crane into stock chest, being fallen in vibrating screen by gravity will be most of
Dust sifts out；
Step 2: starting roots blower, by slice feedstock transportation into storage tank；
Step 3: the valve of storage tank is opened, raw material will be sliced by gravity and fall into drying in drying machine, it is described dry
The operating temperature of dry machine is 170 DEG C；
Step 4: the slice raw material in drying machine being delivered in holding vessel by gravity, drying is set in holding vessel
Device；
Step 5: the slice raw material in holding vessel is delivered in screw extruder by gravity, meanwhile, it will dry
Masterbatch afterwards is delivered in screw extruder, is formed the melt of molten after being sufficiently mixed slice raw material and Masterbatch and is squeezed
Out；
Step 6: melt being delivered in spinning manifold by gravity, is filled by setting in the intracorporal extrusion of manifold
It sets and squeezes out melt from spinneret, form filamentous；
Step 7: filamentous is pooled by boundling circle to after filamentous cooling by tow by air cooling equipment；
Step 8: tow being wound on paper tube by up- coiler.
By using above-mentioned technical proposal, dust is fallen in slice raw material by the effect of gravity, and slice raw material is passed through
The effect of gravity is fallen in vibrating screen, starts vibrating screen, and the dust being largely mixed in slice raw material is sifted out, slice is improved
The degree of purity of raw material, when then being processed slice raw material, that is, the quality for the silk thread that may make is promoted.
The present invention is further arranged to: the storage tank includes tank body, feed pipe and discharge nozzle, the feed pipe position
In the upper end of tank body, discharge nozzle is located at the lower end of tank body, and the tank body is provided with the first dust cleaning machine close to one end of feed pipe
Structure.
By using above-mentioned technical proposal, roots blower will pass through the garbled slice feedstock transportation of vibrating screen to storing pipe
In, the dust being mixed in slice raw material is removed, further by the first dust discharge mechanism so as to further promote slice raw material
Degree of purity.
The present invention is further arranged to: first dust discharge mechanism includes dust flue, drives blower and protective net, described
Dust flue be opened on tank body, the protective net is fixed on the one end of dust flue close to tank body, and the driving blower is solid
Due to the one end of dust flue far from protective net.
By using above-mentioned technical proposal, tank body is injected by the slice raw material that feed pipe is blended with part dust
In, slice raw material is mobile toward the direction close to discharge nozzle by the effect of gravity, during the falling process, a part of dust with cut
It is suspended in tank body after tablet raw material separation, starting driving blower a part of dust is discharged from dust flue, so as to further
The degree of purity for promoting slice raw material, so that the quality of the silk thread manufactured is further promoted.
The present invention is further arranged to: the second dust discharge mechanism is provided in the middle part of the tank body.
By using above-mentioned technical proposal, the dust in tank body is further removed by the second dust discharge mechanism, is further mentioned
The degree of purity for rising slice raw material, keeps the silk thread quality manufactured higher.
