Cut a used medical mask material and you will find that the mask has three layers. Because according to national production regulations, medical masks contain at least 3 layers of non-woven fabrics. In fact, nonwovens are composed of oriented or random fibers. In fact, nonwovens are composed of oriented or random fibers. Every family will have this material, and the most common is the environmentally friendly cloth bag placed in the nursing home.

When making masks, all raw materials are polypropylene (PP), and medical masks are generally SMS structure. The spunbond layer is a single layer, and the meltblown layer can be divided into single layer or multi-layer according to the filtering requirements. Meltblown cloth", commonly known as the "heart" of the mask, is the filter layer in the middle of the mask. It has good filtering, shielding, heat insulation and oil absorption properties, and is an important raw material for the production of masks.

The inner and outer spunbond layers of the meltblown cloth can be To protect sweat and moisture, the meltblown layer in the middle can filter bacteria, thereby preventing the spread of germs and reducing the occurrence of epidemic infections. Therefore, the manufacturing process of the meltblown layer is different from that of the spunbond layer. Let's make a comparison: medical The fiber diameter of the spunbond layer S of the mask is about 1/3 of the hair, and the fiber diameter of the meltblown layer M is close to 1/30 of the hair.

Only finer fibers can ensure better antibacterial filtration. To meet national requirements, poly Propylene high melt index non-woven fabric is the best choice for masks. It can also be used in disposable surgical gowns, bed sheets, covers, absorbent pads and many other medical supplies. It is reported that 1 ton of high melt index fiber materials can produce about 250,000 A bacterial protective mask. With the supply of raw materials, the process of making masks is actually not complicated.
