What is the difference between Lixin fabric, needle punched cotton, leather base cloth and polyester felt for shoe making?
All four arrive at your desk looking like a roll of white or grey cloth — and that is exactly why buyers mix them up. They are four different structures doing four different jobs. Specify the wrong one and the failure shows up later: a tongue that feels like cardboard, a Strobel insole that stretches on the lasting line, a lining that sheds fibre inside the shoe, or a gasket that flattens after two weeks of wear.
This guide compares the four nonwoven and textile materials we produce side by side: what each one actually is, its normal gram weight, its hand feel, where it wins, and where it should not be used.
The 30-second answer
| Material | What it actually is | Weight / thickness | Hand feel | Main job in the shoe | Where it fails |
|---|---|---|---|---|---|
| Lixin fabric | Stitch-bonded nonwoven: a fibre web reinforced with knit yarns, so it behaves like a thin board | 100–600 gsm | Stiff, firm, slight grid texture | Insole bottom cloth for Strobel lasting, lining reinforcement, tongue backing | Hard against skin; visible stitch grid; no thick thermoforming |
| Needle punched cotton | Fibre web consolidated by barbed needles only — no yarn, no weave | 100–500 gsm | Soft, lofty, compressible | Padding for tongue, collar, insole cushion, warm lining | Low tensile strength; fibre shedding on cut edges; compresses flat |
| Leather base cloth | Woven or knitted substrate made to be coated — the skeleton of synthetic leather | 150–450 gsm | Flat, textile, firm | Base for PU / PVC / microfiber leather at the coating factory | Not a finished material; never used directly in shoe assembly |
| Polyester felt | Dense needled or pressed felt, no weave, no yarn | 1–10 mm, 200–600 gsm | Dense, firm, slightly fuzzy | Gaskets and spacers, anti-slip liner, toe puff padding | Limited breathability at high density; 150 °C process limit |
1. Lixin fabric — the reinforcement layer
"Lixin" (丽新布) is the Chinese trade name for a stitch-bonded nonwoven. Instead of glue or heat, a web of fibres is mechanically stitched with fine yarns, which is why you can see a faint grid or rib pattern on the surface. That yarn skeleton is what gives the fabric its tensile strength and dimensional stability — it barely stretches, even when pulled hard on a lasting line.
Advantages
- High tensile strength, good dimensional stability, not easy to stretch
- Made from recycled RPET bottle flakes — eco-friendly, meets brand sustainability requirements
- Good flatness, suitable for laminating with sponge and PU foam
- Resists repeated bending, stable for long-time mass production
Limitations & notes
- Hand feel is relatively hard — not for direct skin contact without a composite sponge layer
- Stitch grid texture is visible; not recommended as a high-end surface cover
- Not suitable for thick thermal compression molding
Recommended application
✅ Suitable: Strobel insole bottom cloth, lining reinforcement, shoe tongue backing for sneaker factories.
❌ Not suitable: direct filling for a tongue that needs a super soft touch.
For brand programmes, ask for the RPET version: recycled content and test documentation can be supplied for sustainability audits. See the stitchbond (LiXin) range.
2. Needle punched cotton — the volume layer
Needle punched cotton is made by punching a fibre web with barbed needles until the fibres entangle. No yarn is involved, so the material has almost no tensile strength but excellent loft and compression recovery. It is the material that makes a collar feel soft and a tongue feel padded.
Advantages
- Soft, lofty hand feel with good compression recovery — comfortable padding for collar and tongue
- 100–500 gsm range; thickness can be adjusted without changing the surface
- Good thermal insulation; holds its shape after die-cutting
- Breathable and cost-efficient for high-volume casual and sports shoes
Limitations & notes
- Low tensile strength — must be laminated or stitched, cannot carry load on its own
- Fibre shedding on cut edges; clean die-cutting or edge sealing is required
- Not dimensionally stable under heavy compression — avoid structural parts
Recommended application
✅ Suitable: shoe tongue padding, collar padding, insole cushion layer, casual shoe lining, warm lining.
❌ Not suitable: structural insole board, direct load-bearing reinforcement.
Browse needle-punched cotton specifications (soft, hard, and die-cut parts).
3. Leather base cloth — the substrate layer
Leather base cloth is not a shoe component in itself. It is the woven or knitted textile that a coating factory covers with PU, PVC or microfiber resin to make synthetic leather. Because the coating follows the substrate, the weave density, width stability and surface evenness of the base cloth decide how the finished leather looks and how evenly the resin is picked up.
Advantages
- Uniform woven or knitted structure gives even coating pick-up and stable width on coating lines
- High breaking strength and tear resistance for PU, PVC and microfiber coating
- Good adhesion to PU resin, low shrinkage after heat setting
- Woven, knitted and brushed / suede versions to match different finished leather hand feel
Limitations & notes
- Not a finished material — for synthetic leather factories only, not for direct shoe assembly
- Color and surface depend on the coating; the base cloth alone has no surface aesthetics
- Needs tension-controlled unwinding; poor handling causes width variation and coating defects
Recommended application
✅ Suitable: base cloth for PU / PVC synthetic leather, microfiber leather substrate, coating and lamination lines.
❌ Not suitable: direct use as shoe lining or insole; sewing without coating.
See leather base fabric options.
4. Polyester felt — the functional layer
Felt is the densest of the four. Fibres are needled and pressed into a solid sheet with no visible weave, which gives it abrasion resistance, shape retention and the ability to be die-cut without fraying. In footwear it usually works out of sight: gaskets in safety shoes, spacers between sole layers, anti-slip liners, toe puff padding.
Advantages
- Dense fibre structure with good abrasion resistance and sound / vibration damping
- Die-cuts cleanly without fraying; holds shape without hemming
- Resists repeated compression — reliable as gaskets and spacers
- Thickness range 1–10 mm and 200–600 gsm, full Pantone color range
Limitations & notes
- Limited breathability at high density; heat can build up in closed footwear
- Polyester felt is not suitable for processing above 150 °C
- Thickness tolerance is wider than woven fabric; heavy compression sets the felt
Recommended application
✅ Suitable: support gasket for safety shoes, midsole spacer, anti-slip liner, toe puff padding.
❌ Not suitable: soft-touch lining against bare skin; elastic or stretch parts.
How to choose in four questions
- Does the part have to hold its shape under tension? Yes → Lixin fabric. It is the only one of the four that behaves like a board. No → continue.
- Is the part only filling volume or adding softness? Yes → needle punched cotton, pick the gram weight by how much loft you need (150–250 g/m² for tongue padding, 300 g/m² and up for insole cushion).
- Will the material be coated or laminated into another product? Coating with PU/PVC/microfiber → leather base cloth. Laminating with foam or sponge → Lixin fabric or cotton, depending on whether you need stiffness.
- Is it a wear part, gasket or spacer? Yes → polyester felt. Check the compression set and the process temperature before you approve the sample.
FAQ

Yes, we can supply REACH and RSL test reports. Other third-party tests (ROHS, physical performance, color fastness) can be arranged per your market requirements.
What is your MOQ?
Small trial orders are acceptable, and we support mixed containers with other shoe materials (EVA sheet, microfiber, insoles). Stock items start from 100–500 kg or 500–1,000 m; custom-developed fabrics usually start from 1,000 m per spec.
