PET Non Woven Fabric Roll (Polyester Spunbond)

PET non-woven fabric is spun from polyester filament, offering outstanding heat resistance, abrasion resistance and dimensional stability for demanding environments. Huayue PET rolls are widely used in filtration media, geotextiles, drainage boards, industrial reinforcement and automotive interiors, with GSM, width and roll length customized per application.

For sustainable sourcing, we supply GRS-certified recycled polyester (RPET) with 30%-100% recycled content. Combined with our dope-dyeing process, colors can be matched to Pantone cards with ΔE≤1.5. Full traceability from raw material to finished roll helps brands pass green trade barrier audits.

The question buyers ask most often is simple: should this application run on polyester or polypropylene? Both are spunbond nonwovens and they look and feel similar, but the polymer sets the limits. PET melts at roughly 250-260 °C against 160-165 °C for PP; PET delivers higher tensile strength and initial modulus with a crisper hand, while PP is softer and cheaper. The table below lines up the deciding properties so you can choose against your service temperature, outdoor exposure, strength requirement and budget in one pass.

The one-line rule: if it runs hot (above 100 °C), stays outdoors for years, or needs stiffness and strength — filtration media, geotextiles, automotive interiors, laminating base — choose polyester (PET). If it is disposable, skin-contact or cost-driven — masks, hygiene products, shopping bags, furniture lining, agricultural cover — choose PP. We run both polymers on our own spunbond lines, with GRS-certified rPET from 30% to 100% recycled content (transaction certificate per batch) on the polyester side. Send us your application, GSM and temperature requirement and we will ship free comparison samples before you commit.

One question comes up in almost every polyester enquiry: can your non-woven be made from recycled material? Yes — and it has been our fastest-growing requirement over the past two years. rPET non-woven starts as post-consumer PET bottle flakes, which are sorted, washed, shredded, pelletised and dried before entering the spunbond line along the same process route as virgin polyester. For brands, that means the polyester content in packaging, shopping bags, automotive interiors or filtration media can count toward recycled-material targets; for European buyers it is also standard practice for packaging and plastics-related compliance and retailer sustainability audits.

Our recycled polyester rolls are certified to the Global Recycled Standard (GRS), available at 30%, 50% and 100% recycled content, with a transaction certificate (TC) issued per batch so brands and third-party auditors can verify the claim. The chain is fully traceable from bottle-flake supplier to finished roll. On performance, rPET non-woven matches virgin polyester closely in tensile strength and heat resistance, covering mainstream uses such as filtration, geotextiles, automotive interiors and packaging. Dope-dyed custom colours remain available with colour difference within ΔE 1.5. One caveat worth knowing: recycled feedstock can shift shade slightly depending on bottle-flake origin, so we sample first and then move to bulk.

• Recycled content options — 30% / 50% / 100%, matched to your application and budget.
• Certification & documents — GRS certificate plus a per-batch transaction certificate (TC) for brand audits and retailer compliance checks.
• Performance & colour — Tensile strength and heat resistance close to virgin polyester; dope-dyed custom colours within ΔE 1.5.
• Typical applications — Packaging and shopping bags, automotive interiors, filtration media, geotextiles and drainage boards, industrial composites.

Polypropylene spunbond covers most bag, packaging and interlining work, but it has a ceiling. PP softens around 150-160 °C and is not recommended for continuous service much above 100 °C. Polyester spunbond sits higher: melting point near 255 °C, with practical continuous service in roughly the 130-150 °C band depending on grade and applied load. Where a roll passes through a hot-air dryer, runs over a heated laminating drum, or sits close to a heat source inside an automotive part, that gap decides whether the web holds its dimensions or shrinks away from the edge.

Three properties matter more than the headline melting point. Dimensional stability under tension decides whether the web tracks straight through a hot oven. Shrinkage at temperature decides whether a finished part stays in tolerance. Tensile retention after heat ageing decides whether a filter still holds its pleats after a few hundred hours in service. Because these move independently, the honest way to specify a high-temperature roll is to state the continuous operating temperature, the dwell time at that temperature, and any tension the web carries — a peak figure alone will get you a cheaper roll that fails quietly in month three. GSM follows the application: filtration media generally sit at 30-120 gsm, laminating and coating bases at 60-150 gsm, automotive trim and reinforcement at 100-240 gsm. Below 100 °C continuous, PP stays the cheaper and softer choice; moving to polyester only pays where heat or dimensional stability genuinely demands it.

• Continuous, not peak, temperature — A 255 °C melting point is not a 255 °C service rating — specify the continuous temperature and dwell time you actually run.
• Shrinkage and dimensional stability — Heat-set polyester holds dimensions through hot ovens; state the maximum shrinkage you can tolerate and the roll gets specified, not guessed.
• GSM by application — Filtration 30-120 gsm, laminating base 60-150 gsm, automotive 100-240 gsm — pick the band first, then the temperature grade.
• Knowing when PP is enough — Under 100 °C continuous, PP is cheaper and softer; switch to polyester only where heat demands it.
