The difference between PP nonwoven fabric and spunlace nonwoven fabric lies in their raw materials and manufacturing processes. “PP” refers to the use of polypropylene as the raw material, while “spunlace” describes the production technique. These two types of nonwovens differ primarily in their processing methods, but the finished fabrics themselves are essentially the same. Now let’s take a closer look at PP nonwoven fabric: the correct term for this material is “nonwoven fabric,” also known as “non‑woven cloth.” It is a type of fabric that does not require spinning or weaving; instead, it is produced by orienting or randomly arranging short fibers or filaments into a web structure, which is then consolidated through mechanical, thermal bonding, or chemical means.

Characteristics of Nonwoven Fabrics: Nonwoven fabrics break away from traditional textile manufacturing principles and boast a short production process, high speed, high output, low cost, wide applicability, and diverse raw material sources. Applications of Nonwoven Fabrics: Their primary uses can be broadly categorized as follows: (1) Medical and Hygienic Nonwovens: surgical gowns, protective suits, sterilization wraps, face masks, diapers, household cleaning cloths, wiping cloths, wet wipes, magic towels, soft towel rolls, beauty products, sanitary napkins, panty liners, and disposable hygienic textiles; (2) Home‑Decorative Nonwovens: wallcoverings, tablecloths, bed sheets, bedspreads, and more; (3) Apparel Nonwovens: linings, fusible interlinings, batting, shaped cotton, and various synthetic leather backings; (4) Industrial Nonwovens: filtration materials, insulating materials, cement packaging bags, geotextiles, and wrapping fabrics; (5) Agricultural Nonwovens: crop protection fabrics, seedling‑raising mats, irrigation fabrics, and thermal insulation curtains; (6) Other Nonwovens: space cotton, thermal and sound‑insulating materials, oil‑absorbing pads, cigarette filters, and tea bags in sachets.

Types of Nonwoven Fabrics: Depending on the production process, nonwoven fabrics can be classified as follows: 1. Spunlace Nonwovens: High-pressure micro‑water jets are sprayed onto one or more layers of fiber web, causing the fibers to entangle and interlock, thereby reinforcing the web and imparting a certain degree of strength. 2. Thermal Bonded Nonwovens: Fibrous or powdered thermoplastic bonding agents are incorporated into the fiber web, which is then heated to melt the material and, upon cooling, forms a bonded fabric. 3. Pulp Air‑Laid Nonwovens: Also known as dust‑free paper or dry‑laid paper nonwovens, these are produced by using air‑laid technology to loosen wood pulp boards into individual fibers, then employing an air‑flow process to collect the fibers onto a forming screen, followed by consolidation into a fabric. 4. Wet‑Laid Nonwovens: Fiber raw materials suspended in an aqueous medium are loosened into individual fibers while different fiber types are blended to form a fiber suspension. This suspension is conveyed to a web‑forming unit, where the fibers are laid down in a wet state and subsequently consolidated into a fabric. 5. Spunbond Nonwovens: After polymers have been extruded and drawn into continuous filaments, the filaments are laid down to form a web, which is then reinforced through self‑bonding, thermal bonding, chemical bonding, or mechanical reinforcement methods, transforming the web into a nonwoven fabric. 6. Meltblown Nonwovens: The manufacturing process involves feeding polymer into the system, melting and extruding it, forming fibers, cooling the fibers, laying them down to form a web, and finally consolidating the web into a fabric. 7. Needle‑Punched Nonwovens: A type of dry‑laid nonwoven, needle‑punched nonwovens utilize the piercing action of needles to consolidate a fluffy fiber web into a fabric. 8. Stitch‑Bonded Nonwovens: Another category of dry‑laid nonwovens, stitch‑bonded nonwovens employ the loop‑forming structure of warp knitting 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.

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.
