What is nonwoven fabric?
Nonwoven fabric is a flat sheet material made directly from fibres or filaments bonded together through heat, pressure, or chemical processes — without weaving or knitting. The most common type is polypropylene (PP) spunbond nonwoven, produced by extruding polymer filaments and thermally bonding them into a continuous fabric. Nonwovens are widely used in hygiene products, medical applications, safety garments, agricultural covers, and packaging.
What is spunbond nonwoven fabric?
Spunbond nonwoven fabric is manufactured by extruding continuous polymer filaments (most commonly polypropylene), drawing them into fine fibres, depositing them onto a conveyor to form a web, and thermally bonding them with heated calendar rollers. The result is a lightweight, strong, and breathable fabric used extensively in baby diapers, bags, agricultural covers, and disposable garments. Olefins produces PP spunbond fabric from 10 GSM to 150 GSM.
What does GSM mean in nonwoven fabric?
GSM stands for grams per square meter — it is the weight of one square meter of fabric in grams. A 20 GSM fabric weighs 20g per square meter and is very lightweight and thin. A 100 GSM fabric weighs 100g per square meter and is heavier and stronger. GSM is the most important specification when selecting nonwoven fabric because it directly affects strength, softness, barrier performance, and cost.
What is the difference between SMS and SMMS nonwoven fabric?
SMS (Spunbond-Meltblown-Spunbond) is a 3-layer composite nonwoven. SMMS (Spunbond-Meltblown-Meltblown-Spunbond) adds a second meltblown layer, improving barrier performance by 30–50% at the same total GSM. SMS is suitable for Level 1–2 medical gowns and hygiene backsheets. SMMS is specified for Level 2–3 surgical gowns and applications requiring higher hydrostatic head resistance.
How much does nonwoven fabric cost per kg?
Nonwoven fabric price from Pakistan ranges from approximately USD 1.40–1.80/kg for standard spunbond PP, USD 1.80–2.40/kg for SMS, and USD 2.00–2.70/kg for SMMS — all FOB Karachi. Prices vary based on GSM, color, treatment, and order quantity. Contact Olefins at info@olefins.net for a precise quotation based on your exact specification and volume.
What is the minimum order quantity for nonwoven fabric from Olefins?
The minimum order quantity at Olefins is 500 kg for standard white spunbond PP in stock GSM grades. Custom colors require a minimum of 1,000 kg. SMS and SMMS fabric have a 1,000 kg minimum. For first-time buyers, we can accommodate smaller trial orders — contact us to discuss your requirements.
How long does it take to produce and ship nonwoven fabric from Pakistan?
Production lead time at Olefins is 10–15 days for standard spunbond orders and 15–25 days for custom color or SMS/SMMS orders. Sea freight from Karachi to UAE takes 5–8 days, Saudi Arabia 7–10 days, Bangladesh 6–10 days, and Europe 18–25 days. Total order-to-delivery time for GCC buyers is typically 3–5 weeks for first orders, faster for repeat orders with stock allocation.
Can Olefins produce nonwoven fabric in custom colors?
Yes. Olefins produces PP spunbond nonwoven fabric in any Pantone color using masterbatch pigment blending. Color is throughout the fabric — not just printed on the surface — so edges and reverse show the same color. Minimum order for custom colors is 1,000 kg per color. Provide a Pantone reference or physical color standard. Lead time for custom colors is 15–20 days.
What surface treatments are available for nonwoven fabric?
Olefins offers several surface treatments: hydrophilic (rapid liquid absorption — for hygiene topsheets and wipes), hydrophobic (water repellent — for hygiene backsheets and SMS medical fabric), UV-stabilized (for outdoor and agricultural applications — 2–4 year outdoor lifespan), anti-static (for electronics and cleanroom applications), and flame-retardant (for industrial safety applications). Treatments are applied during or after production.
How is nonwoven fabric tested for quality?
At Olefins, every production batch undergoes: GSM weight measurement at 5 points across the roll width (tolerance ±3–5%), tensile strength testing per ASTM D5034 in machine direction (MD) and cross direction (CD), elongation testing, visual uniformity inspection, and — for SMS/SMMS — hydrostatic head pressure testing per EN 20811. Test reports are available upon request.
What is the difference between nonwoven and woven fabric?
Woven fabric is produced by interlacing yarn on a loom — a time-intensive process producing a dimensionally stable, durable material suitable for apparel and heavy-duty applications. Nonwoven fabric bypasses yarn spinning and weaving entirely, bonding fibres directly into a sheet structure. Nonwovens are faster to produce, lower in cost, and better suited for disposable and technical applications like hygiene products, medical garments, and geotextiles.
Is polypropylene nonwoven fabric recyclable?
Yes. Polypropylene (PP) spunbond nonwoven fabric is 100% recyclable. PP is Resin Identification Code #5 and can be collected, melted, and re-pelletized for reuse in other PP products. Olefins operates an in-house post-industrial waste recycling programme for production trimmings and defective rolls. However, PP is not biodegradable in standard landfill conditions, which is why recycling collection is important.
What GSM nonwoven fabric should I use for baby diapers?
Baby diaper topsheet (the skin-contact layer) uses hydrophilic spunbond PP in 10–15 GSM for premium grades, 15–18 GSM for standard grades. Backsheet uses hydrophobic spunbond PP laminate in 15–22 GSM. Leg cuffs use spunbond or SMS in 15–25 GSM. Acquisition layer uses through-air bonded or spunbond in 30–60 GSM. Olefins supplies all diaper nonwoven components — contact us for a complete diaper layer specification.
What GSM nonwoven fabric is best for surgical gowns?
Surgical gown fabric GSM depends on the AAMI performance level required: Level 1 gowns (basic barrier) use SMS fabric in 25–35 GSM. Level 2 gowns use SMS in 35–45 GSM. Level 3 gowns (moderate barrier, most common) use SMMS fabric in 45–60 GSM. Level 4 gowns (highest barrier, fluid-intensive surgery) require SMMS or laminated fabric in 60–80 GSM. Olefins supplies SMS and SMMS for Level 1 through Level 3 applications.
What nonwoven fabric is best for reusable shopping bags?
PP spunbond fabric in 80 GSM is the most widely used specification for standard reusable shopping bags. For heavy-duty carry bags, 100–120 GSM is recommended. The fabric should have good tensile strength (minimum 40 N/50mm MD), be printable by screen or flexo, and be consistently uniform for bag machine production. Olefins produces bag fabric in 60–120 GSM in any Pantone color.
Does Olefins export to the UAE?
Yes. Olefins regularly exports nonwoven fabric to buyers in the UAE, with sea freight from Karachi to Jebel Ali (Dubai) taking 5–8 days.

International courier dispatch to GCC, South Asia, and other regions within 3–7 business days.
What is meltblown nonwoven fabric?
Meltblown nonwoven fabric is produced by extruding polymer through very fine die holes with high-velocity hot air, creating ultra-fine fibres of 0.5–5 microns diameter — approximately 10× finer than spunbond fibres. This produces a dense, highly efficient filtration layer. Meltblown is not strong on its own, but when sandwiched between spunbond layers (creating SMS or SMMS fabric), it provides excellent liquid and particle barrier performance for masks and medical garments.
What is the difference between hydrophilic and hydrophobic nonwoven fabric?
Hydrophilic nonwoven fabric is treated to absorb and transmit liquid rapidly — used for hygiene product topsheets where liquid must pass through to the absorbent core. Hydrophobic nonwoven fabric repels liquid — used for hygiene backsheets, SMS/SMMS medical fabric, and agricultural covers where moisture barrier is required. Both are PP spunbond base fabric with different surface chemical treatments applied during production.
How do I verify the GSM of nonwoven fabric I receive?
Use a circular fabric cutter (standard: 100 cm² cut area) and an analytical scale accurate to 0.01g. Cut 5 samples at different points across the roll width, weigh each, and multiply the average weight by 100 to get GSM. Compare to the declared GSM — acceptable commercial tolerance is ±5%. If you consistently receive fabric outside this tolerance, the supplier’s quality control is inadequate.
What payment terms does Olefins offer for international orders?
For new buyers, Olefins requires 50% advance payment and 50% balance before shipment (T/T bank transfer in USD).
