The mystery and diversity of Long Spunbonded Nonwoven Fabric

Long Spunbonded Nonwoven Fabric, that is, long fiber spunbonded nonwoven fabric, as an important part of the nonwoven material field, has shown its unique charm and broad application prospects in many industries in recent years.

The production process of Long Spunbonded Nonwoven Fabric is mainly based on the spunbonded process. This process forms a continuous filament fiber web by melting, extruding, drawing, laying, hot pressing and other steps of high molecular polymer (such as polypropylene, polyester, etc.), and then reinforces it by hot rolling or needle punching, and finally obtains nonwoven fabric. This process not only realizes automated production and improves production efficiency, but also ensures the stability and consistency of product quality.

In the production process, the selection of raw materials, the setting of spinning process parameters, and the control of hot rolling or needle punching conditions all have an important impact on the performance of the final product. The molecular weight, melt index and other characteristics of the raw materials determine the strength and elongation of the fiber; the temperature, pressure, speed and other parameters in the spinning process affect the diameter, morphology and distribution of the fiber; the temperature, pressure and time in the hot rolling or needle punching process determine the density, thickness and air permeability of the product.

Long Spunbonded Nonwoven Fabric stands out among many nonwoven materials with its unique performance characteristics. It has good air permeability, hygroscopicity, softness and wear resistance, making the product outstanding in wearing comfort, skin affinity and durability. It also has the characteristics of light weight, high strength, non-flammable, easy to decompose, non-toxic and non-irritating, making the product also have significant advantages in environmental protection, safety and health.

The diversity and advantages of Long Spunbonded Nonwoven Fabric have made it widely used in many fields. In the medical field, it is widely used in the production of surgical gowns, masks, protective clothing, dressings and other products, providing safe, comfortable and reliable protection for medical staff and patients. In the field of sanitary products, it is used to produce sanitary napkins, diapers, wet wipes and other products, providing consumers with a convenient and comfortable use experience. It is also used in many fields such as automotive interiors, filter materials, building waterproof materials, agricultural covering materials, packaging materials, etc., showing its wide application prospects.

Long Spunbonded Nonwoven Fabric, with its unique production process, performance characteristics, wide application fields and market trends, shows its unique charm and broad prospects in the field of nonwoven materials. In the future, with the continuous advancement of technology and the continuous development of the market, Long Spunbonded Nonwoven Fabric will surely usher in a more brilliant tomorrow.
