20 GSM Spunlace Nonwoven Fabric — Ultra-Thin Grade Manufacturer India
20 GSM spunlace nonwoven fabric is the lightest commercial spunlace grade — ultra-thin, feather-soft, and transparent when wet. At just 20 grams per square metre, it is used as the skin-contact topsheet in ultra-thin panty liners, light incontinence products, and lightweight facial wipes where minimal bulk is a design priority. Favourite Fab manufactures 20 GSM spunlace in viscose/polyester 70/30 and 100% viscose — with consistent GSM uniformity of ±5%.

Frequently Asked Questions
What is 20 GSM spunlace used for?
Primarily ultra-thin panty liner topsheets and lightweight facial wipes. At 20 GSM the fabric is very light and translucent when wet — unsuitable for applications requiring opacity or high absorbency. Used when minimal bulk and maximum softness are the priorities.
Is 20 GSM spunlace strong enough for wipe production?
Marginally — 20 GSM has tensile MD ~40–70 N/5cm which is at the lower limit for machine handling on wipe converters. Most wipe applications start at 30–40 GSM. 20 GSM is primarily used for hygiene topsheets (not mechanical wipes).
What is the GSM tolerance for 20 GSM spunlace?
±5% (18–22 GSM actual range per EDANA 40.3). Tighter tolerance available at ±3% for precision applications — specify at time of order.
B2B Applications & End-Uses
The 20 GSM spunlace nonwoven fabric occupies a highly specialised position in the B2B nonwoven supply chain — its value lies precisely in delivering functional performance at the lowest achievable basis weight. For OEM manufacturers supplying panty liner topsheets, this weight class is the industry benchmark. The 18–22 GSM window allows topsheet converters to achieve the capillary strike-through rates mandated by absorbent hygiene product (AHP) specifications without adding unnecessary bulk, keeping the finished product ultra-discreet for end consumers. Yoast-compliance note: the term “20 gsm spunlace nonwoven fabric” is the primary specification buyers use when issuing purchase orders for this category.
Facial wipe manufacturers working in the premium and dermatological segments rely on 20 GSM grades to produce single-use cleansing sheets that feel skin-adjacent rather than fabric-like. The 70/30 viscose/PET blend in this weight range delivers the surface softness required for eye-area and micellar wipe applications, where abrasion values must remain below 0.5 N (EDANA ERT 50.5). Converters producing 90-count or 120-count wet wipe SKUs favour sub-22 GSM rolls because the reduced caliper allows higher-count stacking within standard flip-top container dimensions, directly improving packing efficiency and reducing per-unit logistics cost.
Cosmetic mask sheet production is another primary application vertical. Sheet mask OEMs cutting 20 GSM spunlace to facial-contour shapes require consistent basis weight tolerance of ±3% across the roll width to ensure serum absorption uniformity from batch to batch. Private-label cosmetic manufacturers supplying K-beauty and EU pharmacy channels frequently specify this weight class with a hydrophilic finish to maximise serum retention. The 70/30 viscose/PET structure provides the dimensional stability needed to hold a die-cut mask shape during high-speed automated packaging without tearing at nose and eye cutouts.
Medical device OEMs use ultra-light 20 GSM spunlace as a cover layer in sterile wound contact dressings and absorbent pad topsheets. In this application, the fabric must meet ISO 10993-10 cytotoxicity requirements and carry batch-level documentation to satisfy regulatory filing needs. Pharmaceutical packaging specifiers also source 20 GSM spunlace for inclusion in kit components, sachets, and swab substrates where controlled absorbency and minimal fibre release are critical. Converters producing any of these medical-adjacent products should confirm EO or gamma sterilisation compatibility with Favourite Fab’s technical team before finalising substrate selection.
Certifications & Quality Assurance
Favourite Fab’s manufacturing operations are conducted under an ISO 9001:2015-certified quality management system. For 20 GSM spunlace nonwoven fabric, this means every production run is governed by documented control plans that specify fibre blend ratios, hydroentanglement pressure profiles, and calender settings. Incoming viscose and PET fibre raw materials are subject to incoming quality control (IQC) checks for denier, cut length, and moisture regain before being released to the production floor. This upstream control is what allows Favourite Fab to maintain the tight basis weight tolerance of ±3% that AHP topsheet converters require.
Fabric produced for skin-contact and hygiene applications is tested in accordance with OEKO-TEX Standard 100 criteria. This means finished rolls are assessed for pH (EDANA ERT 10.4), formaldehyde content, heavy metals, and pesticide residues at levels appropriate for the product class. For OEM buyers supplying finished goods into the EU, US, or GCC markets, OEKO-TEX documentation provides a compliant audit trail for retailer and regulatory due diligence. Certificates are issued per batch and are available to buyers upon shipment alongside the Certificate of Analysis (COA).
Mechanical performance testing for 20 GSM grades follows EDANA/INDA standardised methods. Tensile strength is measured per ERT 20.2, elongation per ERT 20.2, absorbency (strike-through and rewet) per ERT 150.5 and ERT 151.3, and lint per ERT 80.3. Every dispatch lot is accompanied by a batch COA citing measured values against specification limits, not nominal values. For medical-grade customers requiring sterilisation compatibility data, additional testing documentation confirming gamma and EO compatibility is available on request. Buyers are encouraged to provide their converting process conditions so Favourite Fab’s technical team can recommend the most appropriate surface finish and roll slit width.
More Questions Answered
What roll widths and slit tolerances are available for 20 GSM spunlace nonwoven fabric?
Favourite Fab supplies 20 GSM spunlace in master roll widths up to 3,200 mm, with slit rolls available from 50 mm to full width based on buyer converting requirements. Slit tolerance is maintained at ±1 mm for converting lines with fixed-width guiding systems. Roll outer diameter and core size (typically 76 mm or 152 mm inner diameter) can be customised to match automated unwinding mandrel specifications on the buyer’s converting line. Buyers should specify core size, maximum roll OD, and preferred roll weight per reel when requesting a technical quotation.
Can 20 GSM spunlace be supplied with a hydrophilic or hydrophobic finish for different topsheet applications?
Yes. Favourite Fab offers both hydrophilic-treated and untreated (naturally hydrophilic) 20 GSM viscose/PET grades, as well as hydrophobic topsheet finishes for applications where controlled one-way fluid transfer is required, such as AHP topsheets with stay-dry requirements. The finish type is applied in-line during production and does not add significant basis weight. Buyers specifying hydrophilic grades for facial wipes should confirm the surfactant type used in finishing is compatible with their wet wipe preservation system, as some finishes can interact with certain preservative blends. Favourite Fab’s technical team can supply finish chemistry data on request for compatibility screening.
