Spunlace Fabric for Wet Wipes: The Complete Substrate Guide
The wet wipes substrate is the most important specification decision you will make. Here is how to choose fabric that performs with your lotion, converts cleanly, and protects your margin.
Wet wipes are the single largest end-use for spunlace nonwoven fabric. Whether you are launching baby wipes, disinfectant wipes, kitchen wipes, or cosmetic pads, the substrate you choose determines absorbency, strength, softness, and ultimately how well your product works with your lotion. This guide covers every specification that matters.
Why Spunlace Is the Standard Substrate for Wet Wipes
Wet wipes need a fabric that is simultaneously soft enough for skin contact, strong enough to survive pulling from a pack, absorbent enough to hold lotion, and cheap enough to be disposable. Spunlace is the only nonwoven process that delivers all four, which is why it accounts for the vast majority of the global wipes market.
Airlaid and spunbond are used for some budget or specialty wipes, but they cannot match spunlace on the softness-absorbency-strength triangle at the same cost. For a full process comparison, see our spunlace vs spunbond article.
Choosing GSM for Wet Wipes
GSM (grams per square meter) is the first number to pin down. Higher GSM means thicker, stronger, and more absorbent fabric, but also higher cost per wipe. The right GSM depends on your wipe category:
| Wipe Category | Typical GSM | Fiber | Why |
|---|---|---|---|
| Baby wipes | 50-70 gsm | 100% viscose | Softness for skin + enough strength to pull |
| Disinfectant / sanitizing wipes | 45-65 gsm | Viscose/PET blend | Durability against scrubbing, chemical resistance |
| Kitchen / food-surface wipes | 50-75 gsm | Dyed viscose or V/PET | Absorbency + durability for tough cleaning |
| Cosmetic / facial wipes | 50-80 gsm | Viscose or bamboo | Softness and lotion holding |
| Flushable wipes | 50-80 gsm | Wood pulp + PET | Must disperse in water |
Cost Tip
If your current substrate is 70 gsm 100% viscose and you need to reduce cost, test a 60 gsm viscose/polyester blend (70/30). You will often keep wet strength while saving 15-25% on material cost — see our GSM selection guide for details.
Fiber Type: Viscose vs Polyester vs Blends
The fiber composition determines absorbency, wet strength, and cost. Viscose absorbs liquid (hydrophilic), while polyester adds strength that holds up when wet (hydrophobic but structurally strong).
| Fiber | Absorbency | Wet Strength | Softness | Relative Cost | Best For |
|---|---|---|---|---|---|
| 100% Viscose | High | Low | Excellent | Higher | Baby, cosmetic, premium wipes |
| 70/30 Viscose/PET | Good | Good | Good | Moderate | Disinfectant, general cleaning |
| 50/50 Viscose/PET | Moderate | High | Moderate | Lower | Industrial, tough cleaning |
| 100% Polyester | Low | Very high | Lower | Lowest | Technical, non-absorbent applications |
| Bamboo | High | Low | Excellent | Premium | Eco premium wipes |
Surface Patterns for Wipes
The embossing pattern affects how the wipe feels, how much lotion it holds, and how it cleans. The three patterns you will see most often in wipes:
| Pattern | Texture | Typical Use |
|---|---|---|
| Plain | Smooth, even | Baby wipes, general purpose |
| Small Pearl (dot) | Fine texture, better grip | Cosmetic, facial, premium |
| Large Pearl (dot) | Bulkier, more scrubbing action | Kitchen, disinfectant, tough cleaning |
| Mesh (18/22 mesh) | Open structure, high flow | Industrial, cleanroom, lens cleaning |
Lotion Compatibility: The Often-Ignored Factor
The substrate and the lotion are a system. A fabric that works perfectly with one lotion can fall apart with another. Key interactions to test before committing:
- pH compatibility — aggressive lotions can degrade viscose fiber over time
- Preservative uptake — some substrates absorb preservatives unevenly, causing mold issues
- Release properties — the wipe must release lotion onto the surface, not trap it
- Dimensional stability — some lotions cause the fabric to shrink or distort in the pack
Always Run a Compatibility Test
Before placing a production order, always run a 4-8 week accelerated aging test with your actual lotion on the candidate substrate. A substrate that looks fine at week zero can degrade by week six. SunLuner provides lab-scale lotion compatibility testing for qualified customers.

Frequently Asked Questions
1What GSM is best for wet wipes?
50-70 gsm is the standard range for most wet wipes. Baby wipes typically use 50-70 gsm 100% viscose, disinfectant wipes use 45-65 gsm viscose/polyester blends, and kitchen or tough-cleaning wipes use 50-75 gsm. The exact GSM depends on your strength and absorbency requirements.
2Should I use 100% viscose or a viscose/polyester blend for wipes?
For softness-critical wipes like baby or facial wipes, use 100% viscose. For disinfectant, kitchen, or cleaning wipes that need to survive scrubbing, a 70/30 or 50/50 viscose/polyester blend gives better wet strength at lower cost.
3What is the difference between plain and pearl pattern wipes?
Plain pattern is smooth and even, best for general use. Pearl (dot) patterns add texture that improves grip and gives a bulkier, more premium hand-feel. Small pearl is common in cosmetic and premium wipes; large pearl is used for tougher cleaning wipes.
4How do I know if a substrate is compatible with my lotion?
Run an accelerated aging test (4-8 weeks) with your actual lotion on the candidate substrate. Watch for fiber degradation, mold, uneven preservative absorption, and dimensional changes. A reputable manufacturer will provide lotion compatibility testing before production.
5Can I get custom GSM and custom width for my wipes?
Yes. SunLuner produces custom GSM within each line's range and slits to your exact roll width. Custom specifications typically require a minimum order quantity of 3-5 MT. Contact us with your target specification.
