Precision-engineered PP spunbond and composite nonwoven fabric lines optimized for minimal TCO and maximal yield.
Pujiang HG Nonwoven Machinery is a globally recognized manufacturer of PP (Polypropylene) spunbond, meltblown, and composite (SMS, SMMS, SSMMS) nonwoven fabric production lines. Established with a core mandate to deliver high-performance, eco-friendly, and energy-efficient machinery, HG Machinery integrates international 5th Generation spunbond spinning technology with autonomous mechanical innovations tailored to regional and global market demands.
Our engineered solutions empower manufacturers to achieve minimal operational expenditure (OpEx), small physical footprints, low power consumption, and uniform filament density across various basic weight ranges (10 gsm to 250 gsm). By offering comprehensive turnkey engineering—from raw material polymer blending to automated slitting and roll wrapping—HG Nonwoven Machinery stands as a trusted technology partner worldwide.
A comprehensive examination of 5th Generation spunmelt physics, cassette spin packs, high-velocity air attenuation, and thermal calender bonding.
The core of HG Nonwoven Machinery's 5th Generation spunbond technology rests upon high-precision extrusion geometry. Polypropylene (PP) chips with a Melt Flow Index (MFI) of 25 to 40 g/10min undergo controlled thermal plasticization inside high L/D ratio single-screw extruders. The extrusion system utilizes continuous hydraulic screen changers and high-precision metering pumps to guarantee pulse-free polymer delivery to the spinneret assembly. This pressure stability eliminates filament variance, ensuring a coefficient of variation (CV) in web weight of less than 1.5% across wide production widths up to 3.2 meters.
Filament attenuation is governed by supersonic narrow-slot air quenching systems. As molten polypropylene filaments emerge from micro-drilled spinnerets, they encounter conditioned laminar quenching air. The filaments are drawn through closed-system drawing channels where high-velocity air streams stretch the continuous filaments, reducing fiber fineness to 1.2 – 2.5 denier. Higher filament tenacity is attained through precise molecular orientation, enhancing tensile strength in both Machine Direction (MD) and Cross Direction (CD).
In modern industrial applications, single-beam (S) structures are increasingly augmented by multi-beam spunmelt configurations. HG Machinery manufactures complex multi-beam setups:
Tailored machinery configurations engineered for target vertical markets and specific material properties.
Delivers exceptional softness, rapid fluid strike-through, and barrier protection for baby diapers, adult incontinence garments, and feminine hygiene pads.
High-barrier SMS and SMMS nonwovens engineered for surgical gowns, drapes, N95/FFP3 masks, and protective suit coveralls offering biological resistance.
Lightweight, eco-friendly, reusable TNT fabrics optimized for shopping bags, suit covers, rice packaging, pocket springs, and interlining applications.
UV-stabilized crop covers permitting light and water transmission while generating microclimates to protect crops against frost, wind, and pests.
Beyond spunbond machines, HG delivers full-factory automation, inline recycling, slitting, and converting integration.

Strategic innovations driving the next era of sustainable polypropylene and bio-based nonwoven manufacturing.
Transitioning from 100% virgin PP to Poly-lactic Acid (PLA) and post-industrial recycled (PIR) PP blends. HG machinery is recalibrating screw aspect ratios and heating zones to handle temperature-sensitive bio-polymers without compromising spinning speed.
Deploying IoT sensor arrays across calender roll pressure points and thermal heating zones. Real-time edge computing delivers predictive maintenance metrics, automated gsm monitoring, and remote optical defect detection.
Implementing direct-drive servo motors, heat recovery exchangers on quench air handlers, and optimized airflow dynamics. These enhancements lower overall power consumption down to under 0.8 kWh per kilogram of fabric produced.
