80 GSM Spunlace Nonwoven Fabric — Industrial & Medical Grade Manufacturer India
80 GSM spunlace nonwoven fabric is a heavyweight grade used in applications demanding high absorbency, high tensile strength, or thick construction. At this weight, spunlace has sufficient bulk for primary wound dressings, heavy industrial wipes, reusable cleaning cloths designed for extended service life, and medical drape absorbent layers. The 80 GSM range is also standard for automotive wipes and heavy-duty cleaning applications where lower GSM fabrics tear under aggressive use. Favourite Fab supplies 80 GSM in polyester and viscose-dominant blends.

Frequently Asked Questions
What is 80 GSM spunlace used for?
Heavy industrial wipes (oil, chemical, solvent), primary wound dressings, surgical drape absorbent layers, reusable cleaning cloths rated for 25+ wash cycles, and automotive cleaning wipes. The weight provides durability for aggressive mechanical use.
What fibre blend at 80 GSM is best for industrial wipes?
100% polyester at 80 GSM for maximum chemical resistance and reusability. Polyester/viscose 50/50 for a balance of absorbency and strength. 100% viscose for maximum absorbency (wound dressings) but lower mechanical durability.
How does 80 GSM spunlace compare to standard paper shop towels?
80 GSM polyester spunlace is significantly stronger wet and dry than standard paper towels. It withstands mechanical scrubbing without tearing, resists oils and solvents, and can be used multiple times before disposal — making it more economical for high-use industrial applications.
B2B Applications & End-Uses
The 80 GSM spunlace nonwoven fabric at a PET 70/Viscose 30 composition occupies a distinct and technically demanding position in the nonwoven substrate market. At 78–85 GSM, this weight class crosses the threshold from heavy wipe substrate into medical device component and industrial technical textile territory. The blend ratio is intentional: the 70% PET fraction provides the structural integrity needed for EO and gamma sterilisation processes without dimensional distortion, while the 30% viscose fraction maintains the absorbent capacity and drape that medical wound care and surgical application OEMs require.
Wound dressing OEMs and medical device manufacturers sourcing secondary wound care components use 80 GSM spunlace as a primary dressing substrate, wound contact layer backing, or absorbent pad component. The PET-dominant composition at this basis weight provides sufficient wet tensile strength to prevent disintegration during wound irrigation and dressing change, while the viscose fraction absorbs wound exudate at a rate appropriate for moderate-to-high exudate wound categories. Medical device buyers sourcing 80 GSM spunlace as a Class I or Class IIa medical device component must ensure the substrate’s biocompatibility is established per ISO 10993-1, and Favourite Fab’s technical team can provide supporting documentation for cytotoxicity (ISO 10993-5) and sensitisation (ISO 10993-10) assessment.
Industrial wipe converters producing high-duty-cycle maintenance wipes for chemical processing, oil and gas, and heavy manufacturing environments specify 80 GSM PET/viscose spunlace for formats requiring higher caliper and basis weight than 70 GSM grades provide. Applications include pre-saturated industrial solvent wipes, surface preparation cloths for adhesive bonding processes, and equipment cleaning wipes used in food-grade and pharmaceutical manufacturing environments where fabric integrity, low particulate generation, and defined absorption capacity must be simultaneously met. Converters in these sectors typically require documented chemical resistance data for the specific solvents or process chemicals used in their pre-saturation formulas.
Sterilisable packaging material converters and sterile drape OEMs use 80 GSM spunlace as a component in wrapped sterile barrier systems and surgical drape laminates. In these applications, the spunlace layer contributes absorptive capacity and conformability, while compatibility with EO sterilisation (ISO 11135) and gamma irradiation (ISO 11137) is a non-negotiable supply specification. Favourite Fab can provide sterilisation compatibility data confirming that the 80 GSM PET/viscose grade maintains tensile integrity and does not generate harmful extractables following standard sterilisation cycles, supporting OEM regulatory submissions in markets requiring medical device registration.
Certifications & Quality Assurance
The 80 GSM spunlace grade occupies the highest-compliance tier within Favourite Fab’s nonwoven product range. Manufacturing is conducted under ISO 9001:2015 certification, with process parameters for the PET 70/viscose 30 blend at this basis weight documented in grade-specific manufacturing process instructions that specify hydroentanglement pressure, drying temperature profile, and winding tension settings. The elevated basis weight requires calibrated equipment settings that differ from lighter grades to achieve the required uniformity across the 2,400–3,200 mm production width — basis weight CV% across the roll width is monitored and maintained within ±3%.
For medical device applications, Favourite Fab provides a Declaration of Conformity confirming that the 80 GSM grade is manufactured under conditions suitable for use as a component in the buyer’s medical device quality system. Biocompatibility documentation — including cytotoxicity test reports per ISO 10993-5 and chemical characterisation data per ISO 10993-18 — is available to OEM buyers integrating the fabric into a medical device technical file. For EO sterilisation compatibility, Favourite Fab provides data confirming that residual EO levels following standard sterilisation and aeration cycles fall below the limits specified in ISO 10993-7 for skin-contact applications. Gamma irradiation compatibility data (dose range 10–40 kGy) is similarly available on request.
Batch-level COAs for 80 GSM spunlace cite basis weight (ERT 40.3), tensile strength (ERT 20.2) in both dry and wet condition, elongation (ERT 20.2), lint (ERT 80.3), and absorbency (ERT 10.1 and ERT 150.5). For medical applications requiring microbiological cleanliness, the COA can be extended to include total viable count and specified pathogen absence data per the buyer’s product specification. All COA data is traceable to production batch records held in Favourite Fab’s document control system, enabling full batch traceability for regulatory audits and product complaint investigations.
More Questions Answered
How does 80 GSM spunlace PET/viscose perform under repeated EO sterilisation cycles compared to pure PET grades?
The 80 GSM PET 70/viscose 30 blend is validated for standard single-cycle EO sterilisation at temperatures up to 55°C under the conditions specified in ISO 11135. Tensile retention following a single EO cycle is typically ≥95% of pre-sterilisation values for both MD and CD directions, confirming that the hydroentanglement bond structure is not significantly compromised by the sterilisation conditions. For applications requiring multiple sterilisation cycles — uncommon for single-use devices but relevant for sterilisation process qualification studies — Favourite Fab recommends requesting multi-cycle tensile data at the qualification stage. Pure PET grades at equivalent basis weight typically show marginally higher tensile retention over multiple sterilisation cycles due to the absence of cellulosic fibre degradation, and Favourite Fab can provide comparative data to support substrate selection in demanding sterilisation protocols.
What documentation is provided for 80 GSM spunlace integrated into a CE-marked medical device technical file?
Favourite Fab supplies a documentation package for 80 GSM spunlace intended for CE-marked medical device integration that typically includes: ISO 9001:2015 certificate of the manufacturing site; material specification sheet citing fibre composition, basis weight, tensile, and elongation values; Declaration of Conformity confirming production under a documented quality management system; biocompatibility summary referencing ISO 10993-5 (cytotoxicity) and ISO 10993-10 (sensitisation) test data; sterilisation compatibility data for EO and/or gamma as applicable; and batch COA for the specific delivery lot. The documentation package is reviewed with the buyer’s regulatory affairs team at the qualification stage to ensure it meets the requirements of the applicable MDR/IVDR or national medical device regulatory framework in the target market. Additional documentation may be available on request depending on the specific device classification and regulatory pathway.
