Spunbonded Nonwoven Fabric: A Model of Innovative Technology and Diverse Applications

In the vast field of nonwoven fabrics, spunbonded nonwoven fabrics play an irreplaceable role in many industries with their unique process and excellent performance.

The birth of spunbonded nonwoven fabrics is a masterpiece of the innovative process of spunbonding. Spunbonding, also known as melt spinning web method, cleverly uses the principle of chemical fiber spinning. During the polymer spinning process, the extruded melt filaments are cooled by quenched air, and the filaments are formed into continuous filaments by the stretching effect of the stretching airflow. After these filaments are laid into a web, they are processed by a consolidation device and finally become spunbonded nonwoven fabrics. This one-step nonwoven technology greatly shortens the processing of nonwoven fabrics and can also make high-strength and ultra-fine fiber nonwoven fabrics.

From the perspective of materials, spunbonded nonwoven fabrics are rich and varied. Polyester spunbond nonwoven fabrics have many advantages such as high strength, high temperature resistance, aging resistance, and UV resistance. They can be used for a long time in an environment of 150°C, and have high elongation, good stability, and good air permeability. They are widely used in various fields with high performance requirements. Polypropylene spunbond nonwoven fabrics use polypropylene as raw material, with a simple process flow, large output, non-toxic and harmless to the human body, and are widely used in sanitary materials and other fields. In addition, there are spunbond nonwoven fabrics with different characteristics such as plain weave, perforated, hydrophilic, and water-repellent, which meet the personalized needs of different industries.

The performance advantages of spunbond nonwoven fabrics are very significant. It is light, with polypropylene resin as the main raw material, with a specific gravity of only 0.9, only three-fifths of cotton, fluffy and good hand feel; soft, composed of fine fibers, light point hot melt bonding molding, the finished product is moderately soft and comfortable; water-repellent and breathable, polypropylene slices do not absorb water, the moisture content is zero, the finished product has good water repellency, and is composed of 100% fiber with porosity and good breathability; non-toxic and non-irritating, produced with FDA-compliant food-grade raw materials, does not contain other chemical ingredients, has stable performance, is non-toxic, has no odor, and does not irritate the skin; antibacterial and anti-chemical agents, polypropylene is a chemically blunt substance, not moth-eaten, and can isolate the erosion of bacteria and insects in liquids.

In the field of application, spunbond nonwovens have shown strong vitality. In the field of medical and health care, it is a key material for products such as surgical gowns, protective clothing, disinfection wraps, masks, diapers, and sanitary napkins, protecting people's health. In the field of household products, it covers bedding, furniture decoration, cleaning products and other aspects. As consumers' requirements for the quality of home environment increase, its application will be further expanded. In the field of industrial materials, it can be used for various air and liquid filtration materials, new building water-proof materials, new insulation materials and clothing auxiliary materials. In agriculture, it can be used as seedling cloth; it is widely used in automobiles; it is also widely used in construction, cable packaging, civil engineering, clothing, footwear and luggage, household products, filtration industry, packaging, personal care products, protective clothing and other fields.
