PET spunbond substrate fabric production line

Product overview

The PET spunbond substrate fabric production line is a spunbond nonwoven line built to produce high-strength substrate (tire) fabric for SBS and APP modified-asphalt waterproof membranes. It works on the spunbond principle: PET chips (or recycled PET bottle sheets with the matching equipment) are melt-spun into continuous filaments by tubular air drawing, laid into a web, then fixed through an online or offline dipping stage, with an optional reinforcement layer. Compared with short-fiber polyester tire, PET spunbond substrate delivers high tensile strength, superior elongation and dimensional stability, aging resistance, long service life and good wettability, which makes it the internationally recognized base for high-performance waterproof membranes used on roofs, underground structures, tunnels, highways and railway bridges. The line produces fabrics of 80–300g/m² at 2.5–5.0dpf and 2–16m/min, across three work widths of 3.5m, 4.5m and 6.8m for outputs from 3,500 up to 8,600 tonnes per year. Vina Nonwoven is the authorized Huayang representative in Vietnam, advising on line configuration by work width and target output, with installation, commissioning and warranty support.
