A nonwoven fabric machine is production equipment that converts polypropylene (PP) polymer raw material into nonwoven fabric in a continuous process. It is also called a nonwoven making machine, a nonwoven production line, a spunbond nonwoven machine, or a spunmelt nonwoven machine, depending on the beam configuration. For buyers searching for nonwoven fabric machine manufacturers, the first decision is not brand but line type. Single S, SS, SSS, SMS, SMMS, SSMS, and SMMSS configurations produce different fabrics for different end products, from sanitary napkins and masks to automotive interior materials and eco-friendly bags. This article provides a fact-based overview of how nonwoven fabric machines work, what configurations manufacturers offer, which parameters matter, and how to evaluate a supplier.

The Problem: Terminology, Configurations, and Capital Risk

Buyers at the research stage typically search for a nonwoven fabric machine manufacturer without realizing that the industry does not use one uniform name. The same equipment category is marketed as a PP spunbond nonwoven machine, an SMS nonwoven machine, a spunmelt nonwoven machine, or simply a nonwoven production line. These names describe how many spunbond (S) beams and meltblown (M) beams the line carries; each combination produces a different fabric with different strength, softness, and barrier properties.

The second problem is the lack of comparable data. Published parameters such as effective width, production speed, mechanical speed, and filament fineness are the only objective basis for comparing quotations. Some suppliers omit one or more of these values, making it difficult to judge whether a line matches the buyer's end product. Third, nonwoven fabric machines are long-life capital assets. A mistake in layering configuration or width is expensive to correct after installation. The sections below translate these problems into a concrete shortlisting process.

Industry Background: The Nonwoven Machinery Market

Verifiable market context helps buyers understand why spunbond and spunmelt lines dominate investment decisions. According to Dataintelo's non-woven machinery market report, the global non-woven machinery market was valued at approximately USD 6.8 billion in 2025 and is projected to reach USD 12.1 billion by 2034. The same report states that spunbond technology held the largest technology share at 34.2% in 2025, and that Asia Pacific led the market with a 43.7% revenue share.

Polypropylene is the dominant raw material for nonwoven production, used in approximately 72% of global nonwoven fabric output, according to a marketsandmarkets analysis. In China, the export value of spunbonded nonwovens accounted for 37% of the country's total nonwovens export value in 2024, when the total reached USD 4.04 billion (China Customs / Nonwovens Industry). On the compliance side, nonwoven machinery must meet the safety requirements of EN ISO 11111-3:2005+A2:2016, the international standard specifically covering nonwoven machinery. For competitive context, the global landscape includes Reifenhäuser Reicofil, Andritz AG, Oerlikon Nonwoven, and A.Celli Nonwovens. Chinese manufacturers participate with full-line solutions and customized production lines for export markets.

Who Are the Nonwoven Fabric Machine Manufacturers?

Manufacturers of nonwoven fabric machines fall into two broad groups: European machinery groups with multi-decade histories, and Chinese engineering manufacturers that combine process design with fabrication scale. Among the Chinese suppliers, Changzhou LieZen Non-woven Machinery Co.,Ltd. (also known as Lizen Machinery Co., Ltd) is an example of a full-range nonwoven machine manufacturer. Lizen is based in Changzhou, Jiangsu, China, and specializes in polypropylene (PP) spunbond, meltblown, and spunmelt nonwoven lines. The company states that its design goals are high capacity, high quality, reliability, intelligent control, environmental friendliness, and energy saving.

Detailed Solution: Lizen Nonwoven Fabric Machines

Changzhou LieZen Non-woven Machinery Co.,Ltd. is a professional manufacturer of PP spunbond nonwoven machines and spunmelt nonwoven lines. Founded in 2003, the company operates a 30,000 m² factory, employs 270 people, and maintains a 10-engineer R&D team. Its annual output is 50 units, of which 60% are exported; the United States is its main market. To date, Lizen has delivered almost 1,000 complete sets of standardized and customized non-woven production lines in 30 countries.

Lizen's product family covers Single S, SS, SSS, melt blown, SMS, SMMS, SSMS, SMMSS, PET, and bi-component nonwoven machines. In this naming convention, each S is a spunbond beam and each M is a meltblown beam. The number and arrangement of beams define the line type and, in turn, the fabric's hand feel, strength, barrier performance, and cost.

Three representative models illustrate the range: SW-SS (Double Beams PP Spunbond Nonwoven Fabric Machine), SW-SSS (Automatic SSS Spunbonded Polypropylene Fabric Making machine), and SW-SMMS (SMMS Spunmelt Non Woven Machine). The main raw material for the spunbond and meltblown sections is polypropylene (PP); the equipment itself is mainly made from carbon steel, stainless steel, alloy parts, and electrical components.

Published Specifications Comparison (SW-SS / SW-SSS / SW-SMMS)

Data limitation: these values come from the manufacturer's published specification sheets. Achievable output in daily production depends on the raw-material formulation, fabric gram weight, and the specific line configuration. Buyers should use these figures as a comparison baseline and confirm target speed, width, and layer requirements directly with the supplier.

How a Nonwoven Fabric Machine Line Is Structured: Step-by-Step

The production process of a nonwoven fabric machine is organized around the following functional stages, based on the line structure supplied by Lizen:

1. Raw material preparation. The main raw material for the spunbond and meltblown sections is polypropylene (PP), which accounts for roughly 72% of global nonwoven fabric production.

2. Filament formation. Filaments are produced at the fineness values listed in the machine specification: 1.5–2.0 D on the SW-SS and SW-SMMS lines, and 1.5–2.5 D on the SW-SSS line.

3. Layering. The number and arrangement of spunbond (S) and meltblown (M) beams define the line type: SS, SSS, SMS, SMMS, SSMS, or SMMSS. Each additional beam adds a layer of fabric with targeted properties.

4. Quality and temperature control. The line design supports high production stability and uniform fabric gram weight through flexible formula adjustment and a matched closed temperature control system, which improves the finished product qualification rate.

5. Take-up and finishing. Matched auxiliary equipment includes traction units, winding/rewinding devices, fans and air compressors, heating/temperature control, slitting/cutting, and packaging equipment.

6. Automation. The lines are computerized and designed for continuous or semi-continuous operation, with automation levels and online monitoring depending on the configuration and customer needs.

7. Custom configuration. Lizen supports different widths, layer counts, electrostatic treatment, flame-retardant options, and medical-grade clean standards.

Use Cases: Industries and End Products

Lizen nonwoven fabric machines are applicable to the medical and hygiene sectors (masks, protective wear, sanitary napkins, diapers), automotive interior materials, apparel and home textiles, agricultural covers, and packaging and eco-friendly bags. In practice, PP spunbond lines such as the SW-SS and SW-SSS are used for lightweight hygiene and packaging fabrics, while SMS and SMMS lines add meltblown layers and are used where barrier performance matters, such as medical protective wear and masks.

For automotive interior projects, buyers can configure an automotive interior nonwoven production line with the same core machinery and add the required custom options. For hygiene products such as sanitary napkins, a sanitary napkin nonwoven fabric machine configuration typically prioritizes uniform gram weight, softness, and reliable winding. The working condition is mainly continuous industrial operation; lines intended for medical materials may need to be suitable for cleanroom environments depending on the end product.

Lizen delivers projects in three forms: turnkey production line delivery, single-machine supply, and process modification and upgrade projects. The company's recorded export markets include the USA, India, Saudi Arabia, Pakistan, Thailand, Vietnam, and the United Kingdom, among others.
