What are the differences and advantages of SS spunbond non-woven fabrics? 2021-03-23
Spunbond non-woven fabric: After the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then bonded by itself, thermally bonded, chemically bonded or mechanically reinforced to make the web It becomes a non-woven fabric.

SS non-woven fabric: It is made by hot rolling of two layers of fiber net, the finished product is non-toxic, tasteless, and has high-efficiency isolation. Through special treatment of equipment and technology, it can achieve antistatic, anti-alcohol, anti-plasma, and water-repellent properties. .

SS: Spunbond non-woven fabric + spunbond non-woven fabric = two-layer fiber web hot rolled

Spunbond non-woven fabric, the main materials are polyester and polypropylene, with high strength and good high temperature resistance. Spunbond non-woven fabric: After the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then 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.

S non-woven fabric / SS non-woven fabric difference

Under normal circumstances, S and SS can be distinguished by softness.

S non-woven fabrics are mostly used in the packaging field, and SS non-woven fabrics are mostly used in sanitary 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 non-woven fabric has a softer feel than untreated SS fabric, which is suitable for sanitary materials; and SS can also be treated 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 weight per square meter, but it is difficult to distinguish by the naked eye.

Essentially, the difference between S and SS non-woven fabrics lies in the number of nozzles in the machine. The number of letters in the name represents the number of nozzles, so S has one nozzle and SS has two nozzles.

Advantages and characteristics of SS non-woven fabric

S non-woven fabric is softer than other non-woven fabric products.

The material it uses is polypropylene, which accounts for a relatively low proportion of the total. The fluffy feel is better than cotton, and the touch is skin-friendly. The reason why SS non-woven fabric is skin-friendly is that it is soft and consists of many fine fibers.

All products made of fine fibers have strong air permeability, which can keep the fabric dry and easier to clean. This is a non-irritating, non-toxic product that meets the requirements of food-grade raw materials. It does not add any chemical substances to the fabric and is harmless to the body.

SS non-woven fabric has unique antibacterial properties, does not produce moths, and can isolate the presence of bacteria and parasites from the intrusion of liquid inside. The antibacterial properties make this product widely used in medical care.

Non-woven fabrics used in the medical industry are thermally bonded or chemically fixed to some textile fibers and filaments. Through special treatment of the equipment, it can achieve antistatic, anti-alcohol, anti-plasma, water repellent and water production properties.

SS non-woven fabric use

Due to the special functionality of SS spunbond non-woven fabrics, it is now widely used in many fields such as textiles and garments, decorative materials, medical and sanitary materials.

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