Production and sourcing considerations
Cotton interlock 260–300 GSM is a core option for structured T-shirts and premium basics.
For a production quotation, specify the desired fibre composition, finished GSM, usable width, colour or Pantone reference, stretch requirement, surface finish, washing method and quantity per style and colour. A lab dip, strike-off or material sample may be required before bulk approval.
Questions to ask before approving this fabric
- Does the finished weight match the garment structure and season?
- What shrinkage is expected in length and width after the agreed wash test?
- Does the colourfastness meet the end-use and care requirements?
- Will printing, embroidery, washing or bonding change the surface?
- Is the available lot sufficient for production tolerance and replacements?
