Melt-blown fabric extrusion line‘s melt-blown non-woven fabric is a fast-growing non-woven fabric. Known as the shortest one-step polymer production process abroad. As a plastic extruder supplier in China, GWELL’s products have many obvious advantages such as high filtration efficiency, low resistance, soft mesh, and self-adhesion. Therefore, it is widely used in various countries. Its main uses are medium-efficiency and sub-high-efficiency filtration, including air filtration, acid breaking filtration, food hygiene filtration, and industrial dust mask production. In addition, it can also be used as medical and health care products, industrial precision wet wipes, thermal insulation materials, oil-absorbing materials, battery separators, imitation leather base fabrics, etc., which is superior to traditional textile counterparts in many aspects. With the continuous development of post-processing technology, the application fields of meltblown non-woven fabrics will be more extensive.

 Melt-blown fabric mask extrusion line production principle

 

The melt-blown fabric mask extrusion line unit uses polypropylene PP and the material to enter the flow channel of the melt-blown die head after plasticization, and then enters the spinneret after uniform distribution. Cloth, which is the most critical layer of filter material in the middle layer of the mask.

 

Using hot air jet, hot polypropylene is extruded from the pores of the nozzle of the spinneret, extended in the form of fibers, and then collected on a conveyor belt to form a fiber web based on its self-weldability. Many tiny nozzles are arranged on the spinneret, and the molten polypropylene stream ejected from the nozzles is extended by a high-speed air flow and concentrated on the moving conveyor belt to obtain a melt-blown cloth.

melt-blown fabric mask extrusion line process

 

The melt-blown fabric mask extrusion line uses PP materials to extrude spinning masks and melt-blown cloth products. The process flow of the equipment is as follows: PP raw material feeding—melt extrusion—filtration—metering— – Air heating and compression—melt blowing—forming—electrostatic—winding

 

Melt-blown fabric mask extrusion line equipment mainly includes: screw extruder, melt pump, screen changer, melt-blown device, winding device, air system (hot air blower and heater), etc.

  1. The function of the screw extruder is to melt the sliced ​​material.
  2. The function of the melt pump is to measure, control the output and the fineness of the fiber, and transport the melt to the spinneret continuously and evenly.
  3. The function of the screen changer is to filter out the impurities in the melt, so as not to block the spinneret holes.
  4. The function of the winding device is to pack the melt-blown cloth into rolls.
  5. The function of the air system (hot air blower and heater) is to provide the temperature and pressure of the hot air used in the spinning airflow stretching.

Application

  1. Application in the field of air purification: used for air purifiers, as sub high efficiency and high efficiency air filter elements, and for coarse and medium efficiency air filtration with large flow rate. It has the advantages of low resistance, high strength, excellent acid and alkali resistance, corrosion resistance, stable efficiency, long service life, low price and so on. There is no lint phenomenon of filter material falling off in the purified gas.
  2. Application in the field of medical and health care: the dust-proof mouth made of melt blown cloth has small respiratory resistance and is not stuffy. The dust-proof efficiency is as high as 99%. It is widely used in hospitals, food processing, mines and other workplaces that need dust and bacteria prevention. The anti-inflammatory and analgesic film made of products after special treatment has good air permeability, non-toxic and side effects and is easy to use, SMS products compounded with spunbonded cloth are widely used in the production of sanitary products such as surgical clothes and hats.
  3. Liquid filter material and battery diaphragm: polypropylene melt blown cloth is used to filter acidic and alkaline liquids, oil and oil. It has very excellent performance. It has been regarded as a good diaphragm material by the battery industry at home and abroad and has been widely used. It not only reduces the battery cost, simplifies the process, but also greatly reduces the weight and volume of the battery.
  4. Oil absorbing materials and industrial wiping cloth: various oil absorbing materials made of polypropylene melt blown cloth can absorb 14-15 times of their own weight. They are widely used in environmental protection projects and oil-water separation projects. In addition, they can be used as clean materials for oil and dust in industrial production. These applications give full play to the characteristics of polypropylene and the adsorption of superfine fibers prepared by melt blown.
  5. Thermal insulation material: the average diameter of melt blown microfiber is between 0.5 ~ 5m, the specific surface area is large, a large number of micro pores are formed in the cloth, and the porosity is high. This structure stores a large amount of air, which can effectively prevent heat loss and has excellent thermal insulation. It is widely used in the production of clothing and various thermal insulation materials. Such as leather jacket, ski shirt, cold proof clothing, cotton village cloth, etc., it has the advantages of light weight, warmth preservation, no moisture absorption, good air permeability and no mildew.
