SSS Nonwoven: A Key Ingredient in Hygiene Disposable Solutions

In modern industry and daily life, non-woven fabrics, as a new type of material, have gradually attracted widespread attention. Its unique production process and excellent performance have enabled it to be used in many fields. This article will take you to understand SSS non-woven fabrics and their applications in the disposable hygiene products market.

What is SSS Nonwoven fabric?

1. Structure and production process

• Spunbond is a type of polymer extrusion nonwoven fabric. When producing SSS nonwoven fabric, the polymer melt is squeezed out from the capillary holes of the spinneret, cooled and solidified in the air to form fibers, and then these fibers are reinforced into nonwoven fabrics by mechanical, chemical or thermal methods. SSS nonwoven fabrics are composed of three layers of spunbond nonwoven fabrics that are composited together by heat pressing and other methods.

• For example, on the production line, the first layer of fiber web is first formed by the spunbond process, and then the second layer of spunbond fiber web is formed on the basis of the first layer, and finally the third layer. The three layers of fiber web are subjected to composite processes such as hot rolling to make the fibers bond to each other to form an integral SSS nonwoven fabric structure.

2. Performance characteristics

• High strength: Due to the three-layer spunbond structure, SSS non-woven fabric has good tensile strength and tear resistance. Compared with single-layer non-woven fabric, it is less likely to break when subjected to external force. For example, when used to make packaging bags, it can withstand items of a certain weight without being easily damaged.

• Good uniformity: Its fiber distribution is relatively uniform, and the difference in physical properties is small in the entire non-woven plane, whether longitudinally or transversely. This allows it to maintain good consistency during subsequent processing such as printing and cutting.

• Moderate air permeability: It has a certain air permeability and can meet the basic requirements of many products for air permeability. For example, in the application of some medical supplies or sanitary products, it can provide a certain air circulation while ensuring protective performance.

Application of SSS nonwoven fabric in diapers

Core wrapping layer

SSS nonwoven fabric can be used to wrap the core of diapers. The core is the key part of diapers, mainly absorbing and locking liquids. SSS nonwoven fabric can effectively prevent the leakage of absorbent materials (such as super absorbent resins, etc.) in the core, and its good breathability helps reduce the feeling of stuffiness. For example, when the baby wears diapers, after the urine is absorbed by the core, the SSS nonwoven fabric can dissipate the moisture, keep the skin dry, and reduce the incidence of diaper rash.

Outer protective layer

As the outer layer of diapers, SSS nonwoven fabric can provide a soft and comfortable touch. It can prevent liquids such as urine from seeping out, and has a certain degree of tensile resistance to adapt to the baby's physical changes during activities. Its appearance is usually more beautiful, and it can be decorated with printing and other decorations to make diapers more attractive. Moreover, its waterproof performance can prevent external moisture (such as the baby accidentally sitting in a place with water) from entering the inside of the diaper, thereby ensuring the use effect of the diaper.

Fitting material for elastic areas of legs and waist

SSS non-woven fabric can be used as fitting material in the elastic areas of legs and waist of diapers. It can work well with elastic materials to fit the baby's body curves tightly and prevent side leakage. Its softness will not cause marks or discomfort to the baby's skin, ensuring the baby's comfort during wearing.

Application of SSS nonwoven fabric in sanitary napkins

Surface material

SSS non-woven fabric can be used for the surface of sanitary napkins. Its soft and delicate texture can bring comfortable touch to users and avoid irritation to the skin. Moreover, it has a certain hydrophilicity, which can quickly guide liquids such as menstrual blood to penetrate into the absorption layer, preventing liquids from accumulating on the surface and causing side leakage. For example, some brands of sanitary napkins use SSS non-woven fabric surface, which can make users feel more refreshed during menstruation.

Flank material

SSS non-woven fabric is an ideal material for the flank part of sanitary napkins. It can fit well with underwear, and when the flank is attached, the stability of SSS non-woven fabric can ensure the fixed position of the sanitary napkin. At the same time, its flexibility makes the flank not easy to break or deform during activities, which improves the reliability of sanitary napkins.

Bottom layer protective material

As the bottom layer of sanitary napkins, SSS non-woven fabric can play a dual role of waterproof and breathable. It can prevent liquids such as menstrual blood from penetrating into underwear, while keeping the private parts of the user breathable, reducing the generation of stuffiness and odor. This balance of breathability and waterproofness is very important for women's menstrual comfort.

Application of SSS non-woven in other fields

• Medical and health field: It can be used to make surgical gowns, isolation gowns, medical sheets, etc. Because it is strong, can withstand a certain amount of pulling, and has good air permeability, it can reduce the discomfort of medical staff during long-term work. At the same time, its good uniformity is also conducive to disinfection and other treatments.

• Packaging field: It is widely used in food packaging, daily necessities packaging, etc. For example, the packaging bags of some high-end foods use SSS non-woven fabrics to ensure packaging strength while providing a good appearance display effect, and its air permeability can prevent the food from getting damp and moldy.

• Household goods field: It can be used to make curtains, tablecloths, etc. For example, as curtains, its good uniformity can ensure that the curtains have consistent light-shielding and aesthetics in different parts, and its high strength can prevent it from being damaged during repeated pulling.

All in all, sss nonwoven fabrics provide a lot of convenience for our life. If you are looking for SSS nonwoven fabric for production of baby diapers and sanitary napkins, Lonsun is a good chioce for you.
