APPLICATION:
Metal Hollow Fiber Double Wet Spinning Machine Leather-core composite Wet Spinning Machine
DW7091A is suitable for preparation of Metal Hollow Fiber and Leather-core composite fiber ;
The heating ovens should be designed in layer with cover and 1.5kw heating power ,The system should
include spinning device for spandex production.The heating ovens should be designed in layer with cover
and 1.5kw heating power ,The system should include spinning device for spandex production
Features:
1. Metering pump:
Real-time collection of melt pressure and temperature data, panel display;
Pressure sensor and temperature sensor are installed inside the metering pump.
2. Metering pump drive:
Drive by variable frequency gear motor;
Real-time display of motor speed, variable frequency adjustment
3. Spinning system:
Adopting circulating hot water heating, fast and accurate, high thermal efficiency, good insulation effect;
Solid relay control heating element achieves accurate temperature control, durable and noiseless;
Thick 316 stainless steel cylinder to heat material more uniformly.
4. Security of equipment:
Conspicuous warning messages are set for high temperature and dangerous areas.
5. Data monitoring control:
The material temperature is monitored in real time, the wall temperature is controlled and the material temperature is controlled more accurately;
All stainless steel pipe, valve and pressure gauge are used to control air flow;
The temperature control adopts the temperature control meter, PID automatic temperature control, and three-phase program temperature control;
PC remote control, interface display: extrusion speed, hot roller speed, winding speed, metering pump speed, temperature display all necessary alarms and signals.
6. Over-limit alarm:
Over-load alarm: The system will automatically shut down after overloaded;
Over-temperature alarm: if the temperature exceeds the alarm temperature, the heating shall be stopped immediately;
Over-pressure alarm, if over-pressure, the drive motor will shut down;
Abnormal metering pump speed alarm: Automatic alarm display if not the speed consistent with the set
speed.

Material procedure for your reference
Commercially available copper powder (Skyspring nanomaterial, 99%) with a particle size of 1-2 mm
was used as catalyst precursor. N-methylpyrrolidone (NMP, 99.5 wt%, Sigma Aldrich) and polyether imide
(PEI, Ultem 1000, General Electric) were used as solvents and polymers, respectively.
Copper powder (71.09wt %) was added to NMP (22.14wt %), then stirred and ultrasonic treated for 30 min. After adding PEI (6.76wt %), the mixture was heated at 50℃ for 30 min and 60℃ for 2 h. Next, the solution is allowed to cool by stirring overnight and then degassed. Vacuum treatment for 90 minutes and leave overnight.
Spinning: Performed at room temperature (21±3℃) in stainless steel containers, pressurized to 1bar using nitrogen. The mixture is pressed into a condensate bath containing tap water through a spinneret with an inner diameter of 0.8 and an outer diameter of 2.0 mm. The deionized water is pumped through the spinneret hole at a rate of 30 ml min-1 with an air gap set to 1 cm.
After spinning, the fibers are placed in a coagulation bath for 1 day to remove NMP and then dried for 1 day. Green copper hollow fibers were heat treated in air at 600℃(heating and cooling rate 60℃/h-1) for 3 hours to remove PEI and induce sintering of copper particles.
This method ejected fibers: Cross-sectional images show finger-like cavities perpendicular to the surface, consisting of a spongy porous outer layer 10-15 microns thick (FIG. 1c,d). The outer diameter and inner diameter ranges of copper hollow fibers were 1.55±0.1 and 1.3±0.05 mm, respectively (FIG. 1e).
