Question 1

What does GOTS certified mean?

Accepted Answer

GOTS (Global Organic Textile Standard) audits the entire supply chain from organic cotton farming to the finished textile plus social standards. Strictest organic standard. At ShirtStore: models from Stanley/Stella, among others.

Question 2

What is the difference between OEKO-TEX Standard 100 and organic certification?

Accepted Answer

OEKO-TEX Standard 100 tests the finished textile for harmful substances (100 plus parameters). Organic certification (GOTS) audits cultivation, supply chain and social standards. Ideally both. Stanley/Stella combines GOTS organic with OEKO-TEX.

Question 3

Which brand offers the most sustainable textiles?

Accepted Answer

Stanley/Stella: GOTS organic, Fair Wear for years, RE line from rPET and recycled cotton, yearly audits. Mid-segment: B&C Inspire.

Question 4

What does Fair Wear Foundation membership mean?

Accepted Answer

NGO audits working conditions in textile production: wages, working hours, freedom of association, safety. Member brands such as Stanley/Stella audited yearly. Helps in B2B ESG reporting.

Question 5

Are recycled textiles rPET really sustainable?

Accepted Answer

Yes, with caveats. rPET saves 30-50 percent CO2 vs. virgin polyester. Microplastic fibre shedding during wear remains. Optimal: rPET blended with organic cotton — e.g. Stanley/Stella RE line.

Question 6

What distinguishes Lyocell/TENCEL from organic cotton?

Accepted Answer

Lyocell (TENCEL) is cellulose fibre from Austrian eucalyptus wood in closed-loop solvent process (99 percent recovery). Less water than cotton, biodegradable, premium-soft hand-feel. Higher price.

Question 7

Which materials are suitable for allergy sufferers?

Accepted Answer

OEKO-TEX Class I (baby clothing) and organic cotton without chemical dye residues. Stanley/Stella natural white or OEKO-TEX Stedman models for allergy sufferers. For extreme sensitivity undyed natural tones.

Question 8

How do I prove sustainability of products to my own customers?

Accepted Answer

Original certificates as PDF on request for certified brands: GOTS licence Stanley/Stella, OEKO-TEX test reports e.g. from Stanley/Stella, Mantis, Russell and FOTL, Fair Wear Brand Performance Check Stanley/Stella. These documents are free for B2B customers.

Question 9

Are organic models more expensive than conventional ones?

Accepted Answer

Yes, usually noticeably more expensive than conventional mass-market brands, e.g. Stanley/Stella Creator (GOTS organic) well above FOTL Valueweight. Current prices per model, colour and size on the product page or in the configurator. For brand projects with a sustainability story, premium organic usually pays off via higher perceived value.

Question 10

Which material suits which printing process?

Accepted Answer

Organic cotton ideal for DTG. Mass-market cotton and poly-cotton for screen print. Polyester needs sublimation or DTF. Lyocell blends compatible with DTG, embroidery and flex print.
