Spunbond non-woven

Continuous PP filaments extruded, air-drawn, laid randomly onto a forming belt and bonded by a hot embossing calender. Sold by the tonne in rolls; it is the raw material for almost everything else in this family. Distinguished from meltblown (1-5 µm fibres, weak, filtration only) and from needle-punch (mechanically entangled, lofty, no bond dots).

Processes spunbond-nonwoven

Spunbond–meltblown–spunbond sandwich thermally bonded in one pass: the meltblown core supplies hydrostatic barrier and bacterial filtration, the spunbond skins supply strength and abrasion resistance. Not interchangeable with SS, which has no barrier layer.

Processes spunbond-nonwoven · coating

Polymer blown by high-velocity hot air into 1-5 µm fibres collected as a fine web. Structurally weak on its own — always used as a filter core or laminated. Electret (corona or water-charged) grades hold a static charge for high capture at low pressure drop.

Processes spunbond-nonwoven

Staple or filament web mechanically entangled by thousands of barbed needles — thick, lofty, high elongation, no thermal bond points, tears rather than splits. The base for geotextile, filter felt, carpet backing, automotive trim and grow bags.

The same spunbond line running additive masterbatch or a kiss-roll topical finish. Sold as a separately qualified SKU because the performance claim — not the gsm — is what the buyer contracts for.

Typical UV: 1% / 2% / 3% HALS giving roughly 1 / 2 / 3 outdoor seasons (12-36 months at ~120 kLy/yr); FR to NFPA 701, BS 5852 Crib 5, CA TB117, FMVSS 302, EN ISO 15025; hydrophilic wetting time <3 s and strike-through <2 s (diaper topsheet); antistatic surface resistivity 10⁸-10¹⁰ Ω; antibacterial ≥99% reduction vs S. aureus / E. coli per AATCC 100

Spunbond spun from recycled PET flake instead of virgin PP. Slightly stiffer, higher melt point (so different weld settings), duller colour take-up. The product sold is really the GRS certificate — the fabric is a means to it.

Processes spunbond-nonwoven

Molten PE extrusion-coated directly onto spunbond, or a pre-made microporous breathable PE film dry/hot-melt laminated to it. Gives a liquid-proof face while retaining a fabric hand and (in microporous grades) vapour breathability. Not the same as BOPP lamination, which is for print gloss rather than barrier.

Rotogravure-printed BOPP film dry-laminated onto spunbond so the print sits sealed under the film. Produces photographic full-colour, waterproof, wipe-clean promo material — the standard premium nonwoven bag substrate. Supplied as roll or as cut sheets to bag lines.

A D-cut bag with a folded bottom gusset so it stands up and carries volume, but with no side gussets. The intermediate step between the flat bag and the full box bag; runs on a standard bag machine with a bottom-fold unit.

Processes ultrasonic-weld · heat-seal · screen-print

Full four-panel bag with both side and bottom gussets that squares up like a paper carrier. Made on a dedicated box-bag machine (Oyang 15/17, KETE C700 class), optionally with the handle attached online in the same pass.

Flat or gusseted bag with a separate loop of nonwoven tape or PP rope heat-sealed to the inside of the mouth — the paper-carrier-style handle. Runs on an online-handle machine (E700 / Oyang XC class) that forms and attaches the loop in the same pass.

Fully sealed three-side, four-side or back-centre-seam pouch with no handle — inner or protective packaging for textiles, PPE, filters, spare parts, hardware. Runs on the same multi-function bag machine as everything else.

Cut-and-sew construction on industrial sewing lines instead of ultrasonic welding — stronger, allows shaped panels, pockets, bound edges, contrast trim and closures. The quality end of the promo nonwoven bag business and a completely different factory floor from the bag machines.

Mouth threaded with cord that gathers shut; the backpack version runs both cords down to reinforced bottom corners to form shoulder straps. Made on a dedicated cord-threading machine (穿绳机) or by cut-sew.

UV-stabilised, sometimes hydrophilic spunbond laid directly over the crop as a floating row cover, or hung inside a tunnel as a thermal layer. Breathable and water-permeable — that is the entire argument against PE film.
