Non woven composite technology improves product performance and meets diverse needs by combining different materials or processes. The following are the main types of composites, their characteristics, and applications:
Classified by composite process
Hot pressing composite
Hot rolling composite refers to the use of hot rolling technology to composite non-woven fabric with other materials into a new material. The main characteristics of this technology are simple process, high production efficiency, and the ability to obtain high-strength and high-quality composite materials. Its application areas include many fields such as automobiles, furniture, building materials, etc. Hot rolled composite non-woven fabrics are commonly used in fields such as automotive interiors, flooring, and roofing materials.
Adhesive composite
Using water-based or solvent based adhesives, suitable for bonding non-woven fabrics with films and fabrics, commonly used in medical packaging and automotive interiors.
Ultrasonic Composite
High frequency vibration generates local heat for bonding, with no chemical residue, used for medical products and environmentally friendly materials.
Hot air composite
Hot air composite refers to the process of combining two or more materials into a new material using hot air. This technology has the characteristics of simplicity, efficiency, and environmental friendliness, and is a widely used non-woven composite technology. Hot air composite non-woven fabric is commonly used in medical, hygiene, packaging and other fields.
Point attachment composite
Point attachment composite refers to fixing two or more materials together by bonding a point attachment layer on the surface of non-woven fabric. The characteristic of this technology is that the composite area of the material is small, the composite thickness is thin, and the breathability is good, which can alleviate the problems of air tightness and stuffiness caused by excessive composite thickness. Non woven fabrics with point attached composites are commonly used in shoe materials, lining fabrics, handbags, cushioning materials, and other fields.
Classify by material combination
Non woven fabric+film (such as PE film)
Enhance waterproofing, used for medical protective clothing and agricultural covering materials.
Non woven fabric+foam
Improve buffering and sound absorption performance, applied to car roofs and household items.
Non woven fabric+metal foil (such as aluminum foil)
Add insulation and radiation protection functions for industrial insulation materials and protective equipment.
Multi layer structure composite
SMS structure (spunbond meltblown spunbond)
The middle meltblown layer provides efficient filtration, while the outer layer is woven to enhance strength, making it widely used in medical masks and surgical gowns.
Multiple composites (such as sandwich structures)
Combining sound absorption and insulation layers, used as soundproofing materials for automotive interiors and buildings.
4. Functional coating composite
Waterproof/oil resistant coating
Surface coated with fluorocarbon resin, used for outdoor products and industrial protective clothing.
Antibacterial/anti-static coating
Add functional additives, suitable for cleaning materials in medical environments and the electronics industry.
5. Special process composite
wet lamination
Combining fibers and adhesives in a wet state to produce high-density filter materials.
Electrostatic recombination
Using electrostatic field to arrange fibers and enhance material uniformity for efficient air filters.
6. Mechanical reinforcement composite
Acupuncture composite
Fiber reinforcement is used for geotextile and carpet substrates by using needle hooks.
Water jet composite
High pressure water jet interwoven fibers, the product is soft and suitable for wet wipes and high-end wiping cloths.
In the future, with the development of domestic and international economies and the advancement of material technology, non-woven composite technology will continue to innovate and improve. It is expected that more, more efficient, and environmentally friendly new non-woven composite materials and technologies will emerge, providing more diversified and high-quality products and services for various application fields.
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.
