S is a single-layer spunbond non-woven fabric, and SS is a double-layer spunbond non-woven fabric, so what is the difference between them?

1. The difference between S non woven fabric / SS non woven fabric

In general, S and SS can be distinguished by softness.
S spunbond non-woven fabrics are mostly used in the field of packaging, and double-S spunbond non-woven fabrics are mostly used in sanitary materials. Therefore, in mechanical design, the S machine tends to make non-woven fabrics stiff, and the SS machine tends to make non-woven fabrics stiff. softer.
However, after a special process, the S spunbond non-woven fabric feels softer than the untreated SS fabric, which is suitable for sanitary materials; and SS can also be processed to become more rigid and suitable for packaging materials.
Another distinguishing latitude is the uniformity of the cloth, which refers to the stability of the gram weight per square meter, but it is difficult to distinguish it with the naked eye.

In essence, the difference between S and double SS is the number of nozzles of the machine. The number of letters in the name represents the number of nozzles, so S has one nozzle and SS has two nozzles.

2. What is SS non woven fabric and what are its characteristics

It is made of two layers of fiber net by hot rolling. The finished product is non-toxic and tasteless, and has high-efficiency isolation. Through special treatment of equipment and technology, it can achieve anti-static, anti-alcohol, anti-plasma and water-repellent properties.
Spunbond non-woven fabrics, the main materials are polyester and polypropylene, high strength, good high temperature resistance By self-bonding, thermal bonding, chemical bonding or mechanical reinforcement methods, the web becomes a non-woven fabric.
Double S spunbond nonwovens are softer than other nonwoven products.
The material it uses is polypropylene, which is a low percentage of the total. The fluffy feeling is better than cotton, and the touch is skin-friendly. Double it is skin friendly because it is soft and made up of many fine fibers.
All products made from fine fibers are highly breathable, keeping the cloth dry and easier to clean. This is a non-irritating, non-toxic product that meets the requirements of food-grade raw materials, a cloth that does not add any chemicals, and is harmless to the body.
It has unique antibacterial properties, does not produce moths, can isolate bacteria and parasites from the presence of internal fluids, and the antibacterial properties make this product widely used in healthcare.
Nonwoven fabrics used in the medical industry are thermally bonded or chemically fixed to some textile fibers and filaments. Through the special treatment of the equipment, it can achieve antistatic, anti-alcohol, anti-plasma, water-repellent and water-producing properties.

3. Usage of SS non woven fabric

Due to the special functionality of double S spunbond non-woven fabrics, it is now widely used in textile and clothing, decorative materials, medical and health materials and other fields.

It is suitable for the production of baby diapers, diapers, sanitary napkins, adult diapers, hospital hygiene products (non-woven series of sanitary pads, masks, protective clothing, etc.), etc., to improve the quality stability of finished products.
