EXTRUTEX PP Meltblown Nonwoven Fabric Production Lines

Product Overview

The EXTRUTEX PP Meltblown Nonwoven Fabric Production Lines are designed for manufacturing polypropylene (PP) nonwoven materials for filtration, thermal insulation, oil absorption, and other industrial applications. With different machine configurations and production widths, the series provides options for businesses establishing new nonwoven manufacturing facilities or expanding existing production capacity. Meltblown technology converts molten polypropylene into fine fibers using high-velocity hot air. The fibers are collected as a lightweight nonwoven web with a large surface area and a structure that can be engineered for different filtration, insulation, and absorption requirements. EXTRUTEX offers two equipment configurations within this product range: the **EXP-MB Series**, represented by the EXP-MB1600, and the **EX-RPL Series**, available in 600 mm, 1200 mm, 1600 mm, and 2400 mm effective product widths. These configurations provide different production capacities, operating speeds, and total installed power requirements to suit different manufacturing targets. The EXP-MB1600 specification lists an extrusion capacity of 60–80 kg/h and a specified fiber diameter of 0.002–0.005 mm. The EX-RPL Series provides wider options for customers planning production capacities ranging from several hundred kilograms to approximately two tonnes per 24 hours, based on the supplied 25 g/m² product reference. Actual production output and finished-fabric characteristics depend on the raw material, product weight, operating conditions, equipment configuration, and production schedule. EXTRUTEX can help customers assess their required product specifications and select a suitable production-line configuration.

How Meltblown Nonwoven Production Works

1. Polypropylene Feeding

Polypropylene pellets suitable for meltblown processing are fed into the production system. Consistent raw-material quality and suitable polymer properties help maintain stable melting and fiber formation. The appropriate grade should be selected according to the required fabric characteristics and end-use application.

2. Polymer Melting and Extrusion

The extruder heats and conveys the polymer until it reaches a molten state. Temperature, screw speed, melt pressure, and material throughput are adjusted according to the selected PP grade and target production conditions.

3. Melt Conditioning and Delivery

The molten polymer passes through the relevant melt-conditioning components before reaching the meltblown die. Proper melt delivery and suitable filtration help support stable processing and reduce defects associated with contamination or inconsistent flow.

4. Fine-Fiber Formation

The molten polymer exits through small openings in the die. High-velocity hot air draws the polymer streams into fine fibers. Air conditions, polymer properties, die settings, and other process parameters affect fiber diameter and distribution.

5. Nonwoven Web Collection

The fibers are deposited onto a moving collection surface to form a continuous nonwoven web. Collection speed and process settings influence the web's basis weight, uniformity, porosity, and other characteristics.

6. Winding and Finishing

The formed nonwoven material is collected and wound into rolls for storage or downstream conversion. Depending on the finished product, additional equipment may be required for slitting, cutting, lamination, pleating, or filter assembly.

Applications of PP Meltblown Nonwoven Fabric

1. Filtration Products

Meltblown polypropylene is widely considered for filtration media because its fine-fiber structure can be engineered for particular filtration requirements. The performance of the finished product depends on the web construction, basis weight, fiber characteristics, any applicable treatment, and the final filter design.

• Mask filtration media: For suitable filtration layers, subject to material testing and finished-product validation.
• Air purifier filters: For selected air-filtration applications requiring a fine-fiber medium.
• Air-conditioning filtration: For appropriate filter constructions and operating conditions.
• Fume and smoke filtration: For selected filtration products designed and tested for the target particles and conditions.
• Automotive air filtration: For filter-media development according to automotive application requirements.
• Cleanroom filtration: For suitable filtration constructions validated against the required performance criteria.

Medical, respiratory-protection, and safety-critical filtration applications require appropriate performance testing and relevant regulatory approvals. Fiber diameter alone does not establish filtration efficiency or medical-grade status.

2. Thermal Insulation Products

The lightweight structure of meltblown nonwoven material can be considered for selected insulation and padding applications. Potential products include cold-protection layers for ski equipment, gloves, and similar items. Finished-product suitability depends on thermal performance, compression behavior, durability, moisture response, and the construction of the complete article.

3. Adsorption and Oil-Absorption Products

Polypropylene is hydrophobic, making appropriately engineered PP nonwoven materials useful for certain oil-absorption applications. Potential uses include:

• Industrial oil-absorbent pads and rolls.
• Oil-absorbent wipes and cleaning materials.
• Oil collection and containment products.
• Selected spill-response and environmental protection products.

The absorbency, retention, and environmental suitability of the finished material must be verified for its intended use. Applications in waterways or other sensitive environments must also comply with applicable environmental requirements.

Production Quality and Process Control

Consistent meltblown production depends on the coordination of raw-material quality, polymer melting, melt delivery, hot-air conditions, die operation, and web collection. Changes in these parameters can affect the fiber structure and final fabric properties. Quality-control procedures may include:

• Visual inspection for holes, streaks, uneven areas, and other web defects.
• Measurement of effective width and fabric basis weight.
• Evaluation of web uniformity, thickness, and mechanical integrity as required.
• Fiber-diameter measurement using a suitable test method.
• Pressure-drop and filtration-efficiency testing for filter media.
• Absorption capacity and retention testing for oil-absorbent products.
• Thermal-performance testing for insulation materials.

Testing procedures and acceptance limits should be established according to the finished product and relevant standards. The equipment's nominal capacity and operating specifications do not, by themselves, guarantee that the finished fabric meets a particular medical, filtration, environmental, or protective-product standard.

Factory Planning and Equipment Selection

Choosing a suitable meltblown production line requires more than comparing nominal output. Buyers should consider the intended product width, basis weight, target production quantity, operating schedule, material grade, utility availability, and downstream processing requirements. For the EX-RPL Series, the stated total equipment power ranges from approximately 210 kW for the 600 mm model to approximately 620 kW for the 2400 mm model. These values should be used for preliminary planning only until the final equipment configuration and electrical requirements are confirmed. Before ordering, confirm the following items with EXTRUTEX:

• Required effective fabric width and edge-trimming allowance.
• Target fabric basis weight and acceptable weight variation.
• Expected daily and annual production targets.
• Suitable PP raw-material grade and processing requirements.
• Installed power, power supply, and utility requirements.
• Compressed-air, ventilation, and heat-management requirements, where applicable.
• Line layout, operating space, maintenance access, and material handling.
• Winding, slitting, cutting, and other downstream equipment requirements.
• Quality-control instruments and testing procedures required for the target application.
