How Does Spunlace Nonwoven Fabric Production Affect Its Properties?

Sep 25, 2026

If you buy spunlace nonwoven fabric for masks, wipes, dressings or interior use, the data sheet only tells half the story. Softness, absorbency, wet strength and lint level are all decided by production choices: which fibers are blended, how the web is laid, and how hard the water jets hit. This guide explains those links in plain technical terms. Green links marked ⇱ lead to related pages on our site.

How Is Spunlace Nonwoven Fabric Produced?

Spunlace, also called hydroentangled nonwoven, bonds fibers with high-pressure water instead of glue, heat or needles. According to our spunlace nonwoven fabric products page, the web passes under water-jet manifolds at roughly 30 to 200 bar, depending on fiber type and target weight. Because no binder is added, the fabric stays soft and skin-friendly.

Spunlace production process animation Six stages: opening and blending, carding, cross-lapping, hydroentanglement, drying, winding. 1. Open & blendViscose, PET, pulp 2.

Unlike needle punching, which drives barbed needles through a carded batt (see the Tex Tech Industries non-woven fabrics overview), spunlace leaves no needle-hole pattern and gives a smoother, more drapable surface. That is why it dominates skin-contact products.

How Do Fiber Preparation and Blending Affect Fabric Performance?

Fiber choice sets the ceiling for every property. Bale opening and blending must produce a uniform mix, because streaks of one fiber create weak spots and uneven liquid pickup.

  • Fineness and length: Finer fibers give a softer hand and a denser surface. Longer fibers tie together more easily and raise tensile strength, but too-long fibers can tangle in carding.
  • Moisture regain: Viscose can hold up to about 11% moisture under standard conditions, which drives absorbency.
  • Cleanliness: Neps and short fibers raise lint. This matters in medical wound dressing fabric, where shed fibers can irritate a wound.

How Does Carding and Web Formation Change Fabric Structure?

Carding combs fibers into a thin web. A parallel-laid web is strong along the machine direction but weaker across it. Cross-lapping folds the web back and forth, which balances strength in both directions and lets the line build higher weights and widths.

  • Parallel web: Higher MD strength, useful for wipes that are pulled from a roll.
  • Cross-lapped web: More isotropic. Our polyester nonwoven wall cloth relies on this balance to avoid uneven shrinkage, bubbles and seam lifting.
  • Web evenness: Thin spots become weak points after entanglement. Even webs also help serum spread evenly in a facial mask nonwoven fabric.

How Does Hydroentanglement Pressure Affect Spunlace Fabric?

Water jets leave fine nozzles (typically about 100–150 microns) in stacked manifolds. Pressure usually rises step by step: gentle pre-wetting first, then stronger jets on the forming belt or drum. The web is often hit from both sides.

Low versus high hydroentanglement pressure Low pressure: loose, soft, bulky High pressure: dense, strong, low lint

Pressure setting Typical effect Trade-off
Lower Bulky, soft, high liquid capacity Lower tensile strength, more lint
Higher Stronger, denser, cleaner surface Stiffer, less loft, can damage fine or weak fibers
Patterned belt Textured, apertured or embossed look Needs the right web weight and fiber mix

Belt design matters as much as pressure. A smooth belt gives a flat face, while a patterned belt creates surface texture such as the waves in our wavy-textured spunlace kitchen wipes. Water quality and filtration also count: dirty water can clog nozzles and leave stripes.

Viscose absorbs fast but weakens when wet. Polyester holds its shape but absorbs little. Blending is the compromise:

How Do Finishing Treatments Change Spunlace Fabric Performance?

After entanglement, the fabric is dried and can be treated, sized, dyed or printed. Treatments are applied as a padded or coated liquid, then dried and cured. Each one changes the surface, so it should be tested against the end use. Aojia lists custom processes including water repellency, flame retardancy, anti-static, anti-bacterial, anti-aging and anti-UV.

Hydrophilic treatment

Wetting agents lower surface tension so water is taken up quickly. This is important for polyester-rich or synthetic fabrics and for rapid uptake in face towels. Check that the agent is skin-safe and does not wash out too fast.

Antibacterial treatment

Antimicrobial agents limit bacterial growth on the fabric. They suit reusable products and some hygiene uses, but the chemistry must match skin-contact and regulatory needs. Note that antibacterial finishes do not replace sterility.

Antistatic treatment

Polyester builds static charge easily, which attracts dust and makes converting harder. Antistatic agents let charge drain away. They help electronics wiping and dust-removal cloths, such as our wiping cloth series.

Water-repellent treatment

A low-surface-energy finish makes water bead up. It gives up some absorbency, so it fits barrier or outdoor uses rather than wipes.

Flame-retardant treatment

Flame-retardant finishes or FR fibers slow burning. For heavier-duty fire-resistant nonwovens, see the fiber range listed on the Tex Tech Industries page, which covers aramid, PAN and PPS materials. Always confirm the required standard for your market.

Sizing is another common finish. Our nonwoven fabric for curtains uses sizing for a crisp hand and clean pleats.
