Water Electret Melt-blown Cloth Production Line

Water Electret Melt-blown Cloth Production Line

This equipment is used for the production of melt blown nonwoven fabric.Different colors and functions of melt blown nonwovens are produced with polypropylene fiber as the main raw material, supplemented by Color Masterbatch, antioxidant, electrostatic electret, flame retardant and other additives. The products are widely used in industrial felt, industrial oil absorbent cloth, industrial sound insulation cotton, industrial high efficiency filter material, etc. at the same time, the production line can also produce disposable ordinary melt blown cloth for mask and melt blown cloth for mask which can achieve N95 or above high efficiency by adding water electret treatment.

Advantages of water electret meltblown fabrics

The technology of water electret melt blown fabrics originated from the United States, which is different from the traditional process in that the traditional melt blown fabrics uses corona electret, which shows obvious stability and comprehensive benefits, but the filtration efficiency storage will be reduced with time, and the static potential of material surface will be attenuated; and the water electret melt blown fabrics is to transport the prepared pure water through high-pressure water pump To the nozzle, the fan-shaped nozzle is used to spray the melt blown cloth, which makes the water molecules and cloth produce friction and generate static electricity; the advantages of this process are high filtration efficiency, strong static persistence and low ventilation resistance.

High filtration efficiency

The performance of water electret melt blown fabrics is saturated with static electricity. The charging method of water electrostatic electret can pass the oil and salt test of 8130 model. According to the quality of grey cloth, it can easily reach P2 (filtration efficiency 95% +) or P3 (filtration efficiency 99% +);

Electrostatic persistence

After aging resistance and loading test, the water electret melt blown fabrics can still achieve high filtration efficiency, which can be maintained for more than 2 years. Therefore, the water standing technology effectively solves the problem that the electric electret of the mask melt blown cloth is not durable.

Ventilation resistance is small

When the high pressure water molecules penetrate the meltblown cloth, the internal texture of the cloth is combed again, which reduces the ventilation resistance of the cloth by 5% - 30%. That is to say, while reducing the resistance, the filtration efficiency is improved.

Production process

1. Constant tension unwinding

Double position placement,

Constant tension system,

Speed synchronization control

 

2. Spunlace

Pure water preparation: select tap water as the source of water, and complete the preparation of pure water through industrial pure water equipment, with high requirements for conductivity, less than 0.5 μ s.

Water electret process: the prepared pure water is transported to the fan-shaped nozzle through the high-pressure water pump. The fan-shaped nozzle spurs the melt blown cloth, and generates electric charge through friction between the two to complete the spunlace electret.

 

3. Drying

The energy consumption of the oven is about 80 kW, and the drying efficiency is 50% higher than that of the traditional oven, and the output is 50% higher than that of the traditional oven.

 

4. Automatic rewinding / slitting

The machine can automatically record rice and turn over the transfer shaft, cut cloth automatically, integrated PLC control, constant tension control, one key speed regulation of the whole line, and synchronous control of the running speed of unwinding, spunlace and oven.

 

Main equipment parameters

Industrial pure water machine 4T

Actual water consumption: 2-3 tons / hour

Tap water is selected as the water source. The water source is filtered by sand and gravel tank and activated carbon. Reverse osmosis agent and hydrochloric acid are added to the filtered water source. The water source is filtered by reverse osmosis membrane and basic industrial reagent is added to the filtered water source to complete the preparation of pure water

5 μ s.

 

High pressure spunlace (inlet nozzle)

Two or one spunlace can be customized

Water electret process: the prepared pure water is delivered to the fan-shaped nozzle with specific pressure through the high-pressure water pump. The fan-shaped nozzle spurs the melt blown cloth and generates electric charge through friction between the two to complete the spunlace electret.

The advantages of this process are high filtration efficiency, strong electrostatic persistence and low ventilation resistance.

 

Horizontal oven

It has a single node of 6m, a width of 2.2m and a height of 2.5m

Power: 180kW,

Upper and lower circulation air duct, heat energy recycling use.  Compared with the traditional horizontal oven, the drying effect and energy consumption are greatly improved, and the output is more than 50% higher than that of the traditional oven.

 

Vertical oven

It is 3M long, 3M wide and 3.5m high

Power: 120kw,

Vertical roller structure, drying effect is good, and the equipment occupies a small space, thermal energy recycling, energy consumption is small, energy saving about 50%.
