Nonwoven fabric is a type of non‑woven textile that is produced by directly forming fibers—whether polymer chips, short fibers, or filaments—into a web using air‑laid or mechanical processes, followed by reinforcement through hydroentanglement, needle punching, or thermal bonding, and finally finishing. It is a novel fibrous material characterized by softness, breathability, and a flat structure. Its advantages include the absence of fiber lint, exceptional strength and durability, a silky‑soft feel, and a cotton‑like texture. Compared with cotton fabrics, nonwoven bags are easier to shape and more cost‑effective.

Characteristics of nonwoven fabrics: durability, single-use; insulating, conductive; softness, stiffness; fine texture, expansibility; isotropic, anisotropic; filtration, breathable yet waterproof; elasticity, rigidity; lightweight, fluffy, warm; as thin as a cicada’s wing or as heavy as felt; water‑repellent yet moisture‑permeable; suitable for ironing, sewing, and thermoforming; flame‑retardant, antistatic; permeable to water, waterproof, abrasion‑resistant, with a fuzzy surface; wrinkle‑resistant, highly elastic, highly hygroscopic, and water‑repellent.

1. Lightweight: Made primarily from polypropylene resin, it has a specific gravity of only 0.9—three-fifths that of cotton—offering a fluffy texture and a pleasant hand feel.

2. Softness: Composed of fine fibers (2–3D) and formed through a lightweight, dot‑type thermal bonding process. The finished product exhibits moderate softness and a comfortable feel.

3. Water-repellent and breathable: Polypropylene chips are non‑absorbent, with a zero moisture content; the finished product exhibits excellent water repellency. Composed of pure fibers, it is highly porous, offering superior breathability, helping to keep the fabric surface dry and easy to wash.

4. Non-toxic and non-irritating: The product is manufactured using FDA‑compliant food-grade materials, contains no additional chemical additives, exhibits stable performance, is non‑toxic, odorless, and gentle on the skin.

5. Antibacterial and chemical‑resistant: Polypropylene is chemically inert, resistant to insect infestation, and effectively isolates the material from the corrosive effects of bacteria and insects in liquids; it also exhibits resistance to bacterial attack and alkaline corrosion, with its mechanical strength remaining unaffected by such exposure.

6. Antibacterial properties: The product exhibits water-repellent characteristics, resists mold growth, and effectively isolates the material from bacterial and insect infestation in liquid environments, thereby preventing mildew and decay.

7. Excellent physical properties. The product is manufactured by directly laying polypropylene spunbonded nonwoven fabric and then thermally bonding it; its strength surpasses that of typical short-fiber products, with isotropic strength—tensile strength in both the longitudinal and transverse directions being comparable.

8. From an environmental perspective, most nonwoven fabrics currently use polypropylene as their raw material, whereas plastic bags are made from polyethylene. Although the two materials share similar names, their chemical structures differ significantly. Polyethylene has a highly stable molecular structure that is extremely resistant to degradation, which is why plastic bags can take up to 300 years to fully decompose. In contrast, polypropylene’s chemical structure is less robust, with its molecular chains readily breaking down, enabling efficient biodegradation and allowing it to enter the next stage of the environmental cycle in a non‑toxic form. A nonwoven fabric shopping bag can completely decompose within 90 days. Moreover, nonwoven fabric bags can be reused more than ten times, and when discarded, they generate only about 10% of the environmental pollution caused by plastic bags.

Depending on the manufacturing process, nonwoven products can be classified as:

1. Spunlace nonwoven fabric: The spunlace process uses high-pressure, fine water jets to spray a layer or multiple layers of fiber web, causing the fibers to entangle and interlock, thereby reinforcing the web and imparting a certain level of tensile strength.

2. Thermal-bonded nonwoven fabric: Thermal-bonded nonwoven fabric is produced by incorporating fibrous or powdered thermoplastic bonding agents into the fiber web, which is then heated to melt the bonding material and subsequently cooled to solidify, thereby reinforcing the web into a fabric.

3. Pulp‑airlaid nonwoven fabric: Airlaid nonwoven fabric is also known as dust‑free paper or dry‑laid paper nonwoven. It employs airlaid technology to loosen wood pulp fiberboards into individual fibers, then uses an airflow process to aggregate the fibers onto a forming screen, after which the fiber web is consolidated into a finished fabric.

4. Wet-laid nonwoven fabric: In the wet-laid process, fiber raw materials suspended in an aqueous medium are opened into individual fibers and blended with different fiber types to form a fibrous slurry. This slurry is then conveyed to a web-forming unit, where the fibers are laid down in a wet state and subsequently bonded to produce the finished fabric.

5. Spunbond nonwoven fabric: Spunbond nonwoven fabric is produced by extruding and drawing a polymer to form continuous filaments, laying these filaments into a web, and then consolidating the web through self-bonding, thermal bonding, chemical bonding, or mechanical reinforcement to transform it into a nonwoven fabric.

6. Meltblown nonwoven fabric: The manufacturing process of meltblown nonwoven fabric involves the following steps: polymer feeding → melt extrusion → fiber formation → fiber cooling → web formation → consolidation into a finished fabric.

7. Needle-punched nonwoven fabric: Needle-punched nonwoven fabric is a type of dry-process nonwoven fabric. It uses the piercing action of needles to consolidate a fluffy web into a fabric.

8. Stitch-bonded nonwoven fabric: Stitch-bonded nonwoven fabric is a type of dry-process nonwoven fabric. The stitch-bonding process uses a warp-knitted loop structure to reinforce fiber webs, yarn layers, non‑textile materials (such as plastic films or thin metal foils), or combinations thereof, thereby producing a nonwoven fabric.

It is not formed by interweaving or knotting individual yarns; instead, the fibers are bonded directly through physical means. That’s why, when you examine the fabric of your garment, you’ll find that it’s impossible to pull out separate threads. Nonwoven fabrics break with traditional textile manufacturing principles and boast a short production process, high speed, high output, low cost, broad applicability, and versatile raw material sources.

Global nonwoven fabric production has surged! If equipment and technology aren’t upgraded soon, the situation will become critical.

In 2015, manufacturers of polypropylene spunbond and meltblown nonwovens in the nonwoven industry fully capitalized on the market value of this technology, enjoying strong growth momentum. For example, the Argentine nonwoven company Scalter announced the acquisition from a Chinese firm of a polypropylene spunbond production line with an annual capacity of 8,000 tons. Reportedly, this line comprises two spunbond lines, two chemical-bonding lines, one thermal-bonding line, a printing machine, and knitting equipment, all installed at its Buenos Aires plant, thereby enhancing Scalter’s existing operational efficiency. Investing in the most cutting-edge equipment has enabled Scalter to—

Nonwoven fabric is a type of non‑woven textile that is produced by directly forming fibers—whether polymer chips, short fibers, or filaments—into a web using air‑laid or mechanical processes, followed by reinforcement through hydroentanglement, needle punching, or thermal bonding, and finally finishing. It is a novel fibrous material characterized by softness, breathability, and a planar structure. Its advantages include the absence of fiber shedding, high strength, durability, silk‑like softness, and a cotton‑like feel. Compared with cotton fabrics, nonwoven bags are easier to shape and more cost‑effective. Key characteristics of nonwoven fabrics include: durability versus disposability; insulating versus conductive properties; softness versus stiffness; density versus bulkiness; isotropy versus anisotropy; and filtration capabilities.
