Preferably, upper oil nozzle is the spray oil feeding system with measuring pump.
Compared with prior art, the present invention has the following advantages: divide different positions by spinning silk position, the mixed fine networking of the synchronous spinning of pre-oriented yarn (POY) and full-drawn yarn (FDY) and tow is compound, realized that original liquid coloring, spinning, drawing-off, four processing link one-step method of networking finish, the technological process of production is short, and production efficiency is high, and the energy consumption loss is little, pollutant emission reduces, ecological, environmental protective; Because the heat-shrinkable of pre-oriented yarn (POY) and full-drawn yarn (FDY) terylene thread fiber, physical difference such as stretching property, stiffness and flexibility by force, behind networked compound before reeling, formation has the special construction of two heterogeneous " core-skin " that triangle, the profiled-cross-section POY fibre bundle cortex such as multi-leaf-shaped and conventional circular cross-section FDY fibre bundle sandwich layer distribute, whole colored tow not only had the POY silk soft feel, but also have body bone and the intensity of FDY silk, be the desirable ecological, environmental protective new material that color polyester silk simulate wool fashion clothing fabric is produced.
Description of drawings
Fig. 1 is the production technological process of the colored composite terylene silk of One-step production in the embodiment of the invention.
The specific embodiment
The present invention will be described in detail below in conjunction with accompanying drawing.
The production technological process of the colored composite terylene silk of One-step production as shown in Figure 1, concrete said method comprising the steps of:
A. the polyester slice in the chip bunker 1 is delivered to and carries out drying in the chip dryer 2, be delivered to then that heating and melting becomes melt in the screw extruder 3.
The used polyester of the present invention is polyethylene terephthalate (being called for short PET), the PET raw material is through vibration screening, screened out the particle that powder and particle diameter are not inconsistent, obtaining satisfactory section raw material is delivered in the chip bunker 1 for subsequent use, before melting, also section to be delivered to and carry out drying in the drying machine 2, remove the moisture in the section.Dried section enters carries out heating and melting in the screw extruder 3.Adopted single screw extrusion machine 3 in the embodiments of the invention, be compared with existing technology, equipment and process is more succinct, is easy to control.
B. the Masterbatch in the Masterbatch feed bin 12 is fully dry in master batch drying machine 13, by behind small screw implanter 14 heating and meltings through measuring pump 14 accurate measurements enter the section screw extruder 3 PET melt output channel, with the PET melt, mix the Uniform Dispersion dyeing that realizes the PET melt through dynamic mixer 16.
Colored composite terylene silk of the prior art generally is after having weaved composite fibre, again row dyeing, and this follow-up dyeing process is seriously polluted.And in the present embodiment, adopt Masterbatch to dye to entering spinning manifold 4 melt before, environmentally safe, and uniform coloring is stable.In the preferred embodiment, can according to actual needs antiultraviolet age resister, antistatic additive etc. be integrated in one with color master-batch, namely multifunctional mother granules conveniently uses, can be in order to weave the fabric of functional diversities.
Can on the production line of former polyester colored fiber long filament, transform this equipment according to the technical scheme among the present invention in the actual production, realize original liquid coloring, spin, drawing-off and four processing link one-step method of networking finish.
