Spunbond nonwoven fabric
After extruding and stretching the polymer to form continuous filaments, the filaments are laid into a web, which is then subjected to self bonding, thermal bonding, chemical bonding, or mechanical reinforcement methods to turn into non-woven fabric.
SS non-woven fabric
Made by hot rolling two layers of fiber mesh, the finished product is non-toxic, odorless, and has efficient isolation. Through special treatment of equipment and processes, it can achieve anti-static, alcohol resistant, plasma resistant, water repellent and other properties.
SS: spunbond non-woven fabric+spunbond non-woven fabric=two layers of fiber web hot-rolled
Spunbond nonwoven fabric, mainly made of polyester and polypropylene, has high strength and good high temperature resistance. Spunbond nonwoven fabric: after extruding and stretching polymers to form continuous filaments, the filaments are laid into a web, which is then self bonded, thermally bonded, chemically bonded or mechanically reinforced to become nonwoven fabric.
S is a single-layer spunbond non-woven fabric, and SS is a double-layer composite spunbond non-woven fabric.
Under normal circumstances, S and SS can be distinguished by their softness.
S non-woven fabric is mostly used in the packaging field, while SS non-woven fabric is mostly used in sanitary materials. Therefore, in mechanical design, S machines tend to make non-woven fabric stiff on the ground, while SS machines tend to make non-woven fabric softer.
However, after special processing, the softness of S non-woven fabric exceeds that of untreated SS fabric, making it suitable for sanitary materials; SS can also be processed to become more rigid and suitable for packaging materials.
Another way to distinguish 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. Essentially, the difference between S and SS non-woven fabric 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.
Characteristics of SS spunbond nonwoven fabric
SS non-woven fabric has unique antibacterial properties, does not produce moths, and can isolate the presence of bacteria and parasites invading the internal liquid. The antibacterial properties make this product widely used in healthcare.
The non-woven fabrics used in the medical industry are fixed with textile fibers and filaments using thermal bonding or chemical methods. Through special treatment of the equipment, it can achieve anti-static, alcohol resistant, plasma resistant, water repellent, and water producing properties.
Characteristics of non-woven fabric: durability, disposable. Insulation and conductivity. Flexibility, rigidity. Fine and expansive. Filtration, breathable and impermeable. Elasticity and rigidity.
Light, loose, warm. Thin as cicada wings, thick as felt.
Waterproof and breathable. Ironing, stitching, and molding. Flame retardant and anti-static. Permeable, waterproof, wear-resistant, and velvety. Wrinkle resistant, excellent elasticity, high moisture absorption, and water repellent.
Application of SS spunbond nonwoven fabric
Due to the special functionality of SS spunbond nonwoven fabric, it is widely used in various fields such as textile and clothing, decorative materials, medical and health materials, etc.
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.), etc., to improve the quality stability of finished products.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
