Kain underwear harus dinilai dari skin comfort, stretch recovery, breathability, opacity dan dimensional stability, bukan hanya nama fiber.
Apa yang perlu dicek saat sourcing kain underwear?
Kain underwear harus dinilai dari skin comfort, stretch recovery, breathability, opacity dan dimensional stability, bukan hanya nama fiber.
The final use should be described clearly: briefs, bra, lining, lingerie panel, waistband, shapewear or sleepwear. Once the use is clear, composition, GSM, width, colour, stretch, handfeel and finishing become easier to discuss.
- Confirm skin contact, lining or support use.
- Check GSM, usable width, stretch and recovery after relaxation.
- Review opacity in the real production colour.
- Ask about shrinkage, bowing, skew and spirality control.
Apakah melange fabric cocok untuk underwear?
Melange fabric can work for underwear if softness, recovery and wash stability are controlled. It gives a softer, more casual colour effect than a flat solid shade.
The buyer still needs to check pilling, shade variation, shrinkage and seam twist after washing.
- Ask where the melange effect comes from.
- Compare shade across rolls.
- Check pilling risk on soft or brushed surfaces.
Mesh vs nylon sama atau tidak?
Mesh is a fabric structure. Nylon is a fibre. A mesh fabric may be nylon, polyester or spandex blend. A nylon fabric may be mesh, tricot, jersey or another construction.
For underwear, nylon spandex mesh can feel soft and stretchy; polyester mesh may suit quick-dry or print needs; power mesh is more about support.
| Question | Meaning | Factory check |
|---|---|---|
| Mesh vs nylon | Structure compared with fibre | Confirm construction and composition. |
| Breathable underwear fabric | Airflow plus skin comfort | Check openness, GSM and handfeel. |
| Melange fabric | Colour effect plus comfort | Check yarn route, shade and wash stability. |
| Spirality test | Twist or skew risk | Check washing result and seam position. |
Mengapa spirality dan bowing penting?
Spirality, bowing and skew can move seams, stripes and panels after washing. Underwear panels are small, so distortion can become visible quickly.
Factory review should connect yarn twist, knitting tension, heat setting, relaxation, washing and cutting direction.
- Check bow and skew across full fabric width.
- Relax stretch fabric before measuring.
- Keep approved sample and test notes for repeat orders.
Referensi test apa yang berguna?
Not every project needs heavy testing, but if fit, comfort or claims matter, the test direction should be discussed early.
ISO 9237 can support air permeability discussion, ISO 6330 washing procedures, ISO 5077 dimensional change and AATCC TM179 skew change.
- ISO 9237 air permeability standard page Useful when breathability or airflow needs a measurable test method.
- ISO 6330 washing and drying procedures Common reference point when buyers discuss home laundering conditions for textile testing.
- ISO 5077 dimensional change after washing and drying Relevant when shrinkage and fit stability are part of underwear fabric approval.
- AATCC TM179 skew change after home laundering Useful context for skew and spirality discussions in knitted fabrics and garments.
Brief praktis untuk factory
A good enquiry is simple and specific. It tells the factory the final product, target fabric behaviour and approval standard.
- Final garment use and market.
- Composition, GSM, width and colour.
- Stretch direction and recovery.
- Melange, solid colour, mesh openness or support target.
- Testing and tolerance before bulk.
FAQ
What is the best underwear fabric?
There is no single best fabric. The right choice depends on skin comfort, stretch, opacity, stability and garment use.
Is melange fabric good for underwear?
Yes, when it is soft enough and stable after washing. Pilling, shade, shrinkage and recovery still need checking.
Is mesh more breathable than nylon?
Mesh is a structure and nylon is a fibre. Nylon mesh can be breathable, but closed nylon fabric may not be.
What is spirality?
A twist or skew tendency that can move seams or panels after washing or wearing.
What should be sent for sampling?
Garment use, reference sample, composition, GSM, width, colour, stretch, finishing, quantity and test requirement.
