A 70/30 label declares 70% polyester and 30% polyamide, while 80/20 declares 80% polyester and 20% polyamide. The ratio is only one construction field. Wholesale buyers should also compare whether the yarn is split, the weave and pile, finished GSM, edge, size, tolerance and the evidence supporting the declared composition. Do not assume the ratio alone determines softness or absorbency.
1. Treat the blend as a declaration
Record the legal entity that supplied the composition, the product code and date. Keep the field supplier-declared until a suitable quantitative analysis is linked to the identified sample.
2. Keep construction fields separate
A 70/30 towel and an 80/20 towel can also differ in country of origin, yarn processing, weave, pile, GSM and edge. Those variables prevent a blend-only comparison.
3. Define the verification route
AATCC TM20A is a quantitative fiber-analysis reference. The buyer and supplier must confirm the current method, specimen identity and whether the requested analysis is suitable for the material.
4. Match the label to the destination market
When textile labeling rules apply, confirm fiber content, country of origin and responsible-business requirements for the destination market before approving retail packaging.

Review the quality and evidence processCommon questions
Is 70/30 always a premium microfiber blend?
It can be used in premium products, but the label alone does not prove product quality. Construction and evidence must be reviewed together.
Can two suppliers use different methods and report the same blend?
They can provide the same declaration, but comparability depends on product identity, method and evidence scope.
Should the blend appear on retail packaging?
That depends on destination-market labeling requirements and the exact product. Packaging copy should be reviewed before production.
