Differences and advantages of SS spunbond nonwovens

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 self-bonded, thermally bonded, chemically bonded or mechanically reinforced. Turn the web into a non-woven fabric.

SS non-woven fabric

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

Spunbond non-woven fabric, the main material is polyester and polypropylene, high Spunbond non-woven fabric with good strength and high temperature resistance: After extruding and stretching the polymer to form continuous filaments, the filaments are laid into a web, and the web is then self-bonded, thermally bonded, chemically bonded or mechanically bonded Reinforcement method to turn the web into a non-woven fabric.

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

The difference between S non-woven fabric and SS non-woven fabric

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

S non-woven fabrics are mostly used in the field of packaging, and SS non-woven fabrics are mostly used for sanitary materials, so in the mechanical design, the S machine tends to make the non-woven fabric stiff, and the SS machine tends to make the non-woven fabric stiff. The cloth is softer.

But after a special process, S non-woven fabric feels softer than 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 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 non-woven fabrics lies in the number of nozzles of the machine. The number of letters in the name represents the number of nozzles, so there is one nozzle for S and two nozzles for SS.

The advantages and characteristics of SS non-woven fabrics

S non-woven fabrics are softer than other non-woven products.

The material it uses is polypropylene, which accounts for a low percentage of the total. The fluffy feeling is better than cotton, and the touch is skin-friendly. SS non-woven fabric is skin-friendly because it is soft and consists of many fine fibers.

All products made from fine fibers are highly breathable, keeping the fabric 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.

SS non-woven fabric has unique antibacterial properties, does not produce moths, can isolate the intrusion of bacteria and parasites from the presence of internal liquids, and the antibacterial properties make this product widely used in healthcare.

Nonwoven fabrics used in the medical industry are thermally bonded or chemically secured 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.

Features of non-woven fabrics: Durability, Disposable. Insulating, conducting. Softness, stiffness. fineness, expansion. Filterability, breathable and impermeable. Elasticity, stiffness.

Waterproof and breathable. Ironing, sewing, moulding. Flame retardant, antistatic. Water-permeable, waterproof, wear-resistant, fleece. Wrinkle resistance, good elasticity, high moisture absorption, water repellency.

Use of SS non-woven fabrics

Due to the special functionality of SS spunbond non-woven fabrics, it is now widely used in textiles and garments, decorative materials, medical and health materials, etc. kinds of fields.

Suitable for the production of baby diapers, diapers, sanitary napkins, adult diapers, hospital hygiene products (non-woven series such as sanitary pads, masks, protective clothing, etc.), and improve the quality and stability of finished products sex.
