By stage. Machine data for each process section.

Fiber preparation

Opening, blending, and feeding matched to fiber type, blend ratio, and line throughput.

  • Fiber typesNatural, synthetic, regenerated, recycled
  • Opening / blendingBale opener and multi-component blending
  • Carding feedUp to 2.500 kg/h carding capacity (line-dependent)
  • ConditioningDust extraction and controlled fiber transport

Web formation

Carding with parallel (randomized) or cross-lapped layouts ahead of hydroentanglement.

  • LayoutsHigh-speed parallel; crossed / cross-lapped
  • Working width2.500 – 4.500 mm (typical line widths)
  • Parallel line≈ 30 – 95 g/m²; winding up to ~200 m/min; MD/CD ≈ 3–4 : 1
  • Cross-lapped line≈ 30 – 150 g/m²; winding up to ~120 m/min; MD/CD ≈ 1–1,5 : 1

Hydroentanglement

High-pressure water-jet bonding with stainless injectors and recirculating filtration.

  • Working width1.000 – 4.000 mm (unit); lines up to 4.500 mm
  • Jet pressureup to 250 bar
  • Design speed100 – 350 m/min (spunlace unit window)
  • Injector bodySUS304 forged hydroentanglement heads

Slitting and winding

Precision cutting and roll build with controlled tension for clean edges and stable geometry.

  • Cut methodsRazor, score, crush-cut
  • Drive typesSurface, center, combination
  • Winding speedMatched to upstream process window

Packaging

Automatic packaging for jumbo and slitted rolls — wrap, band, label, and handle for storage and dispatch.

  • Roll formatsJumbo / mother rolls and slitted daughter rolls
