Application of melt blown fabric
Melt blown fabric has very good filtering, shielding, heat insulation and oil solubility. Melt blown fabric is the core material of masks, such as KN95 masks. In addition, melt blown fabric has many other uses.

1. Air purification

Filtration is a whole process of separation. Its porous structure and process performance of small round holes determine its solid barrier properties, that is, good filtration properties. If there is electret treatment to increase the electrostatic performance, the actual effect of the filter can also be improved. The described properties of melt blown fabric are used in the room air conditioning filter system, filter element material, dust collector filter bag, etc. When used in air filtration, the melt blown composite material treated by electrostatic electret has the characteristics of low initial resistance, large dust holding capacity, and high filtration efficiency. It is widely used in electronic manufacturing, food, beverage, chemical industry, airport, hotel and other places. Air purification treatment.

2. Oil-absorbing wipes

Melt blown fabric is a pure natural oil-absorbing raw material, and its key raw material is PP. PP hardly absorbs moisture but has very good oil absorption and solubility, and the melt blown fabric has the characteristics of high porosity and high bulk density. The melt blown non-woven fabric becomes an oil-absorbent wipe after the hydrophilicity is resolved. It can be used for cleaning and wiping precision instruments and equipment. In order to prevent fibers from falling off during use and affecting use, low-temperature hot rolling processes are often used to increase the surface strength of the melt blown fabric.

3. Oil-absorbing cotton

Melt blown fabric has very good oil removal characteristics, and its strong suction effect can be used to absorb dirty oil, such as oil spill safety accidents on water, oil leakage from machinery and equipment in processing plants, and wastewater treatment. Oil-absorbing cotton is also called digestion and absorption cotton, and industrial production absorption cotton. The production and processing technology of oil absorbent cotton is the first to obtain melt blown non-woven fabric, and then make various methods of oil absorbent felt, oil pillows, fritters, oil suction cords and oil booms. Because PP fiber has good hydrophobicity and lipophilicity, low density, low water absorption, and stable chemical characteristics such as insoluble in oil and acid and alkali resistance, it is a very good oil-absorbing material. The oil absorption of the melt blown non-woven fabric produced from PP raw materials is 15-17 times its own weight, and the water absorption is 0.07-1 times its own weight. It has the characteristics of fast oil absorption, long-term floating on the water surface after oil absorption, and reusability. It is currently the most commonly used oil-absorbing material.


4. Warm-keeping materials

The average diameter of the ultra-fine fibers of melt blown fabric is between 0.5 and 5m, and the bulk density is large. A lot of ultrafine particles are generated in the cloth with high porosity and high porosity. Its air thermal conductivity is much smaller than that of ordinary fibers. A lot of gas is stored in this kind of structure, which can reasonably block heat loss and has good thermal insulation properties. It is widely used in the production of clothing and various thermal insulation materials. For example, leather jackets, ski shirts, cold-proof clothes, cotton village cloth, etc. can be made, which have the advantages of light weight, cold and warmth, no moisture, good air permeability, and no mold.
