GOTS-certified organic cotton has become essential for responsible children's fashion brands. This guide details the different types of available fabrics, their technical characteristics, and their optimal uses for manufacturing children's and baby clothing.
The Global Organic Textile Standard (GOTS) is the benchmark certification for organic textiles. It guarantees that the fabric contains a minimum of 70% certified organic fibers (95% for the "organic" label) and that the entire production chain adheres to strict environmental and social criteria.
GOTS traceability covers the entire chain: from cotton cultivation (without pesticides or GMOs) to spinning, weaving, dyeing (dyes without heavy metals), and manufacturing. Each link is audited annually by an independent body (Control Union, Ecocert, etc.). The Transaction Certificate (TC) accompanies each batch of fabric and attests to its organic origin.
GOTS social criteria include: prohibition of child labor, guaranteed minimum wage, safe working conditions, and freedom of association. These requirements are aligned with ILO conventions and complement social certifications like BSCI or WRAP.
Organic cotton jersey (150-220 g/m²) — Bodysuits, pajamas, baby and children's t-shirts. Soft, stretchy, ideal for babywear.
Organic interlock (180-250 g/m²) — Trousers, coveralls, sleepsuits. Double-sided, thicker than single jersey.
Organic poplin (100-130 g/m²) — Shirts, dresses, blouses. Lightweight and structured warp-and-weft fabric.
Organic fleece (250-350 g/m²) — Sweatshirts, jackets, winter trousers. Brushed or terry loop interior for warmth.
Organic corduroy (200-300 g/m²) — Trousers, dungarees, jackets. Distinctive texture, strong and durable.
Organic cotton voile (60-90 g/m²) — Ceremonial dresses, linings, ruffles. Sheer and airy.
An essential technical tip: always request a "handfeel" sample in addition to the color card. Two organic jerseys of the same weight can have a very different feel depending on the quality of the spinning and the finishing treatment. At LOI Confection, we send physical samples within 5 business days to allow our clients to validate the fabric before launching production.

Organic cotton cultivation uses 91% less water, 62% less energy, and zero chemical pesticides compared to conventional cotton (source: Textile Exchange). For garments in direct contact with babies' skin, this also guarantees health safety, as pesticide residues are absent.
In terms of carbon footprint, organic cotton emits 46% less CO₂ than conventional cotton over its entire life cycle. Crop rotation practiced in organic farming also improves soil health and biodiversity—an ecosystem benefit that goes beyond a simple carbon balance. For brands subject to the CSRD (Corporate Sustainability Reporting Directive), this data constitutes measurable and verifiable environmental performance indicators.
Sourcing GOTS-certified organic cotton requires rigorous planning. The main producing countries are India (51% of global production), Turkey, China, and Tanzania. Lead times are generally 4 to 8 weeks for standard fabrics and 8 to 12 weeks for special fabrics (atypical weights, cotton-linen blends).
LOI Confection maintains a permanent stock of the most in-demand organic fabrics (170 g/m² jersey, 200 g/m² interlock, 120 g/m² poplin) to reduce production lead times. For special fabrics, we work with a network of GOTS-certified suppliers who guarantee complete traceability from the spinning mill.
GOTS certified since 2015, LOI Confection masters the entire process of manufacturing in organic cotton: sourcing certified fabrics, manufacturing on dedicated lines to avoid cross-contamination, and documented traceability at every stage. Our expertise in eco-design complements this responsible approach.
Our GOTS manufacturing process imposes a strict separation: organic fabrics are stored in a dedicated area, cut on cleaned tables, and assembled on identified lines. Each batch is accompanied by a traceability file including the fabric's TC, cutting sheets, and quality control reports. This level of rigor is audited annually by Control Union.
GOTS certifies the entire production chain (from fiber to finished product) and requires a minimum of 70% organic fibers. OEKO-TEX Standard 100 only tests for the absence of harmful substances in the finished product, with no requirements for the cultivation method. The two certifications are complementary: a fabric can be both GOTS and OEKO-TEX certified.
Yes, untreated organic cotton can shrink by 3 to 5% in the first wash (compared to 1-2% for chemically pre-shrunk conventional cotton). At LOI Confection, we incorporate this shrinkage into our patterns by adding a 4% margin to the dimensions. We also offer an in-factory pre-wash for brands that request it.
GOTS certification imposes strict restrictions on dyes: no heavy metals (chromium, nickel, copper), no aromatic amines, and a minimum biodegradability of 70%. GOTS-certified reactive dyes are the most common. Natural dyes are also compatible and increasingly in demand.
Organic cotton batiste (80-120 g/m²) and organic cotton voile (60-90 g/m²) are perfectly suited for ceremonial dresses. They offer the same drape and embroidery capacity as their conventional counterparts, with the guarantee of healthy contact with babies' skin—a decisive selling point for christening gowns.
The material cost for organic cotton is 15 to 30% higher than for conventional cotton of equivalent quality. This extra cost is decreasing each year as the area of organic cultivation increases. In terms of final retail price, the surcharge is marginal (€2-5 per piece) and is largely offset by the marketing value of the GOTS certification.
