How to distinguish spunbond non woven fabric and meltblown fabric?

 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 and there are no technical problems. The key lies in the material aspect. Many new-born mask manufacturers have never been involved in the mask industry and cannot distinguish between spunbonded 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 spunbond non woven fabric and meltblown fabric raw materials


Spunbond non woven fabric: mostly use polypropylene pellets as raw materials.


Melt blown cloth: mainly use polypropylene as raw material.


2. The difference between the advantages of spunbond non woven fabric and meltblown fabric

Spunbond 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, fluffy structure and good anti-wrinkle ability. 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 filterability, shielding, heat insulation and oil absorption.


3. The difference between spunbond non woven fabric and meltblown fabric structure and application

Spunbond non woven fabric: There are no warp and weft threads, and it is formed by high temperature melt spinning. It is very convenient to cut and sew. It is light and soft. It can be treated with water resistance, hydrophilicity, and UV resistance. It is widely used in hygiene materials, industry, and agriculture. Wait.

Melt blown cloth: It can be used in air, liquid filter materials, isolation materials, absorbing materials, mask materials, thermal insulation materials, 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, which is mainly used to isolate droplets, particles, acid mist, microorganisms, etc.

Opening the  non woven fabric napkin  after ordering a meal is prepared to prevent clothes from getting dirty during the meal. Each restaurant is somewhat different, but most of them are placed on the table with no creases or folds. In restaurants, napkins are usually opened after ordering. Before the meal is decided, only the aperitif is ordered. Since there is no need to worry about dripping on the clothes, it is against table manners to open the napkin at the beginning. Fold the napkin in half and place it on the knee. Open the napkin and fold it in half, and place the napkin on the knee with the opening facing forward. The purpose of folding in half is to prevent the napkin from being pulled by mistake, while the opening is outward to facilitate picking up and wiping the mouth. But for those who often get their clothes dirty, they can also open a whole napkin and clip it on the...
