Nonwovens are fabric-like materials made of staple fibers (short) and long fibers (continuous long) bonded together by chemical,mechanical,thermal or solvent treatment.The term is used in the textile manufacturing industry to refer to fabrics that are neither woven nor knitted,such as felt.Some nonwovens lack sufficient strength unless densified or reinforced by a backing.In recent years,nonwovens have become an alternative to polyurethane foam. 


Nonwovens are broadly defined as sheets or webs of fibers or filaments bonded together by mechanical,thermal or chemical means (and by perforated films). They are flat or tufted porous sheets made directly from individual fibers,molten plastic or plastic film.They are not made by weaving or knitting,and do not require the fibers to be converted into yarn.Usually, a certain proportion of recycled fabrics and oil-based materials are used in nonwovens.The percentage of recycled fabric varies depending on the strength of the material required for a particular use.Additionally, some nonwovens can be recycled after use if properly treated and facilityd.For this reason, nonwovens are considered by some to be a more ecological fabric in certain applications,especially in areas and industries where single-use or single-use products are important,such as hospitals, schools, nursing homes and luxury accommodation.Nonwovens are engineered fabrics that can be single-use, have a limited lifespan,or be extremely durable.Nonwovens have special functions such as water absorption, liquid repellency, resilience, stretchability, softness, strength, flame retardancy, washability, cushioning, heat insulation, sound insulation, filterability, Acts as a bacterial barrier and sterility.These properties are often combined to create a fabric suitable for a specific job, while achieving a good balance between product longevity and cost.They can mimic the look, texture and strength of woven fabrics and can be as bulky as the thickest padding.Used in combination with other materials, they provide a range of products with different properties,which can be used alone or as an integral part of clothing, home furnishings, healthcare, engineering, industrial and consumer goods.

Non-woven materials are used in numerous applications, including: Nonwoven fabric-jiatecairfilte


  • Isolation gowns

  • Iurgical gowns

  • Surgical drapes and covers

  • Surgical masks

  • Surgical scrub suits

  • Caps

  • Medical packaging: porosity allows gas sterilization

  • Gloves

  • Shoe covers

  • Bath wipes

  • Wound dressings

  • Drug delivery

  • Plasters


  • Asoline, oil and air – including HEPA filtration

  • Water, coffee, tea bags

  • Pharmaceutical industry

  • Mineral processing

  • Liquid cartridge and bag filters

  • Vacuum bags

  • Allergen membranes or laminates with non woven layers


Nonwoven geotextile containers (sand bags) are used for

  • Soil stabilizers and roadway underlayment

  • Foundation stabilizers

  • Wrosion control

  • Canal construction

  • Drainage systems

  • Geomembrane protection

  • Frost protection

  • Pond and canal water barriers

  • Sand infiltration barrier for drainage tile

  • Landfill liners

    They are more capable of handling than their woven counterparts and are therefore often preferred in large erosion protection projects such as those at Amrumbank West; Narrow Neck, Queensland; Kliffende House and Eider Barrage on Sylt .In the last case, only 10 out of 48,000 bags were damaged despite a high installation rate of 700 bags per day. 


  • Diapers, feminine hygiene products and other absorbent materials

  • Carpet backing, primary and secondary

  • Composite materials

  • Sail laminate

  • Tablecloth laminate

  • Chopped strand mat

  • Machine embroidery backing/stabilizing paper

  • Packaging requiring porosity

  • Shopping Bag

  • Insulation (fiberglass batting)

  • Soundproofing of appliances, automotive components and wall panels

  • Pillows, cushions, mattress cores and upholstery pads

  • Comforter or quilt

  • Consumer and medical masks

  • Mailing envelope

  • Tarps, tents and transport (wood, steel) packages

  • Disposable clothing (foot covers, coveralls)

  • Weather resistant housing wrap

  • Cleanroom wipes

  • Plant potting material

Manufacturing processes

Nonwovens are usually produced by putting small fibers together in a sheet or web (similar to paper on a paper machine) and bonding them mechanically (as in the case of felt,by bonding them together with serrated needles). interlocking so that friction between fibers results in a stronger fabric), using adhesives or heat (by applying the adhesive (in the form of powder, paste or polymer melt) and melting the adhesive to online).

Staple nonwovens

Staple fiber nonwovens are produced in 4 steps. The fibers are first spun to a few centimeters long and then baled.The short fibers are then blended, "opened" in a multi-step process, dispersed on a conveyor belt, and spread into a uniform web by wet-laying, air-laying or carding/cross-lapping processes. Wet-laid operations typically use fibers that are 0.25 to 0.75 inches (0.64 to 1.91 cm) long, but sometimes longer if the fibers are stiff or coarse. Airlaid processing typically uses fibers ranging from 0.5 to 4.0 inches (1.3 to 10.2 cm).Carding operations typically use fibers about 1.5 inches (3.8 cm) long. Rayon, once a common fiber in nonwovens, has been largely replaced by polyethylene terephthalate (PET) and polypropylene. Fiberglass wet laid for roofing and tiles.Synthetic fiber blends are wet-laid with cellulose for disposable fabrics. Staple fiber nonwovens are bonded thermally or with resin.Bonding can be done throughout the fabric by resin saturation or overall thermal bonding, or in different patterns by resin printing or thermal point bonding. With staple fiber usually refers to the combination with meltblown, usually used in high-end textile insulation materials.
