S Nonwoven/SS Nonwoven Difference

SS Nonwoven: It is hot-rolled from two layers of fiber mesh. The finished product is non-toxic and tasteless, and has high-efficiency isolation. Through special treatment of equipment and processes, it can achieve anti-static, anti-alcohol, anti-plasma, and water-repellent properties.

SS: spunbonded nonwoven fabric + spunbonded nonwoven fabric = hot rolled two-layer web

Spun-bonded non-woven fabric, the main materials are polyester and polypropylene, high-strength, high-temperature-resistant performance. After self-bonding, thermal bonding, chemical bonding or mechanical reinforcement, the fiber web becomes a non-woven fabric.

S is a single-layer spunbond non-woven fabric, and SS is a double-layer composite spunbond non-woven fabric.

Normally, S and SS can be distinguished by softness.

S Nonwoven is mostly used in the packaging field, and SS Nonwoven is mostly used in hygienic materials. Therefore, in mechanical design, the S machine tends to make the non-woven fabric stiffer, and the SS machine tends to make the non-woven fabric softer.

However, after a special process, S Nonwoven feels softer than untreated SS cloth and is suitable for hygiene materials; while SS can also be treated to become stiffer and suitable for packaging materials.

Another distinguishing latitude is the uniformity of distribution, which refers to the stability of the gram weight per square meter, but it is difficult to distinguish with the naked eye.

In essence, the difference between S and SS Nonwoven lies in the number of nozzles of the machine, the number of letters in the name represents the number of nozzles, so S has one nozzle, SS has two nozzles
