Since the spread of the new crown pneumonia epidemic, masks have become a must-have item for everyone to travel. Stimulated by the huge market, mask manufacturing companies have sprung up like mushrooms. The process of making masks is very simple, there are no technical problems, and the key lies in the material aspect-many new-born mask manufacturers have never been involved in the mask industry and cannot distinguish between spunbond non-woven fabrics and meltblown non-woven fabrics, which has caused many problems. Although what is the difference between non-woven fabric and melt blown fabric? Let’s take a look:

1. The difference between non-woven fabric and meltblown fabric raw materials

Non-woven fabric: Polypropylene pellets are mostly used as raw materials.

Melt blown cloth: mainly use polypropylene as raw material.

2. The difference between the advantages of non-woven fabrics and meltblown fabrics

Non-woven fabric: moisture-proof, breathable, flexible, light weight, non-combustible. It is easy to decompose, non-toxic, non-irritating, rich in color, low in price, environmentally friendly, and recyclable.

Melt blown cloth: fiber diameter can reach 1 to 5 microns. There are many voids, the structure is fluffy, and the ability to resist wrinkles is good. The ultra-fine fibers with unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the meltblown cloth has good filtering, shielding, heat insulation and oil absorption.

3. The difference between the structure and application of non-woven fabric and melt blown fabric

Non-woven fabric: There is no warp and weft, it is formed by high-temperature melting and spinning. It is very convenient for cutting and sewing. It is light and soft. It can be treated with water resistance, hydrophilicity, and UV resistance. It is widely used in hygiene, industry, agriculture, etc.

Meltblown cloth: It can be used in air, liquid filter materials, isolation materials, absorbing materials, mask materials, thermal insulation materials, and oil-absorbing materials and wipes. Melt blown cloth is the core material of masks.

Medical masks and N95 masks are composed of spunbond layer, meltblown layer and spunbond layer, referred to as SMS structure. The most important thing inside is the melt blown layer M (ie the filter layer), commonly known as the heart of the mask-melt blown cloth, mainly to isolate droplets, particles, acid mist, microorganisms, etc.
