Classification of nonwoven fabric materials:

Because it is a fabric formed without spinning or weaving—instead, short fibers or filaments are aligned in a specific or random orientation to create a fibrous web, which is then reinforced through mechanical, thermal‑bonding, or chemical processes—simply put, it is not constructed by interlacing individual yarns. Rather, the fibers are directly bonded together using physical methods. That’s why, when you examine the fabric of your clothing, you’ll find that no individual threads can be pulled out. Nonwoven fabrics break with traditional textile manufacturing principles and boast advantages such as a short production process, high speed, high output, low cost, broad applications, and diverse raw material sources.

I. Spunlace Nonwoven Fabric

The spunlace process involves spraying high-pressure, fine water jets onto one or more layers of a fibrous web, causing the fibers to entangle and interlock, thereby reinforcing the web and imparting it with a certain degree of strength.

II. Heat-Sealed Nonwoven Fabric

Thermally bonded nonwoven fabric refers to a process in which fibrous or powdered thermoplastic bonding agents are incorporated into the fiber web, and the web is then subjected to heating to melt the bonding agents, followed by cooling to solidify and reinforce the fabric.

III. Pulp-based airlaid nonwoven fabric

Air-laid nonwoven fabric is also known as dust-free paper or dry‑laid paper. It is produced by using air‑laid technology to loosen wood pulp fiberboards into individual fibers, then employing an air‑flow process to aggregate these fibers onto a forming screen, after which the fiber web is consolidated into a finished fabric.

IV. Wetlaid Nonwoven Fabric

Wet-laid nonwoven fabric is produced by dispersing fiber raw materials in an aqueous medium to separate them into individual fibers, while simultaneously blending different fiber types to form a fibrous suspension. This suspension is then conveyed to a web-forming unit, where the fibers are laid down in a wet state and subsequently bonded to create the final fabric.

V. Spunbond Nonwoven Fabric

Spunbond nonwoven fabric is produced by extruding and stretching 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.

VI. Meltblown Nonwoven Fabric

The production process of meltblown nonwoven fabric is as follows: polymer feeding → melt extrusion → fiber formation → fiber cooling → web formation → consolidation into a fabric.

VII. Needle-punched Nonwoven Fabric

Needle-punched nonwoven fabric is a type of dry-laid nonwoven; it uses the piercing action of needles to consolidate a fluffy web into a fabric.

VIII. Stitch-Bonded Nonwoven Fabric

Stitch-bonded nonwoven fabric is a type of dry-laid nonwoven. The stitch-bonding process uses a warp-knitted loop structure to consolidate fiber webs, yarn layers, nonwoven 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.

2022-11-21

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.
