The difference and advantages of SS spunbond non-woven fabric

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


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, Water and other properties.


SS: Spunbond non-woven fabric + spunbond non-woven fabric u003d two-layer fiber web hot rolled


Spunbond non-woven fabric, the main materials are polyester and polypropylene, high strength, 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 net. The fiber web then undergoes self-bonding, thermal bonding, chemical bonding or mechanical reinforcement methods to turn the fiber 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.


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 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 more rigid. soft.


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 treated to become stiffer and suitable for packaging materials.


Another distinguishing latitude is cloth uniformity, 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.


The advantages and characteristics of SS non-woven fabrics


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


The non-woven fabric used in the medical industry is to fix some textile fibers and filaments by thermal bonding or chemical methods. Through the special treatment of the equipment, it can achieve antistatic, anti-alcohol, anti-plasma, water repellent and water production properties.


Features of non-woven fabrics: durable, disposable. Insulating and conductive. Softness and stiffness. Density and expansion. Filterability, breathable and impervious to water. Elasticity and stiffness.


Light, loose and warm. Thin as a cicada's wings, thick as felt.


Waterproof and breathable. Ironing, stitching, and compression molding. Flame retardant and antistatic. Water-permeable, waterproof, abrasion-resistant, and flocking. Wrinkle resistant, good elasticity, high moisture absorption, water repellency.


SS non-woven fabric use


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


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