PET spunbond substrate fabric production line

This line produces high-strength PET spunbond substrate fabric used as the tire for SBS and APP modified-asphalt waterproof membranes. That substrate fabric is widely applied in waterproofing works such as building roofs, underground structures, high-speed railways, tunnels, and highway/railway bridges.

The primary feedstock is PET chips; the line can also process PET bottle sheets when fitted with the corresponding equipment.

Three work widths are offered: 3.5 m (3,500–4,500 t/y, offline/online fixed dipping), 4.5 m (4,600–5,700 t/y, offline/online) and 6.8 m (6,900–8,600 t/y, offline only); all three support a reinforcement configuration.

The line produces PET spunbond substrate fabric at 80–300 g/m², with 2.5–5.0 dpf denier, a production speed of 2–16 m/min, using tubular air drawing.

They differ in end product, basis-weight range and work width. The substrate line (this one) makes the tire for modified-asphalt waterproof membranes, running 80–300g/m² at 2.5–5.0dpf across three widths — 3.5m, 4.5m and 6.8m — for 3,500–8,600 t/y; only this line offers the offline/online fixed-dipping option. The geotextile line produces needle-punched geotextile for construction, running a wider 100–800g/m² at 2.5–5.5dpf across 4.5m, 6.2m and 7.0m for 5,500–11,000 t/y. Both use tubular air drawing and run at 2–16m/min.

Cost depends on the work width and reinforcement configuration selected, so Vina Nonwoven needs to discuss your requirements to provide an accurate quote. Contact Vina Nonwoven — the Vietnam representative for Huayang — via hotline or Zalo for consultation and pricing.
