The Production Process of Sustainable Organic Cotton

Many clothes are printed with "100% organic cotton", but there is no GOTS certification mark or China organic product mark and organic code. This product may use organic cotton as its raw material when spinning, but its fabric production, printing and dyeing, and garment processing may all be the same as conventional products. So what is sustainable organic cotton, and what are the differences in its production process?

Ⅰ. Selection of sustainable organic cotton varieties

Cotton varieties must come from well-developed organic agricultural production systems or wild natural cotton varieties collected organically, and genetically modified cotton varieties is prohibited.

Ⅱ. Irrigation requirements for sustainable organic cotton soil 

Fertilization is mainly organic fertilizer and biological fertilizer, and irrigation water is pollution-free water. After the last application of chemical fertilizers, pesticides and other prohibited materials in organic production standards, no chemical products can be used within three years, and the first production season will be verified as the "organic transition period" after an authoritative organization has tested the standard. After the transition period, it can become an organic cotton field.

Ⅲ. Sustainable organic cotton residue detection

When applying for organic cotton sustainable field qualification certification, it is necessary to provide the residual content of heavy metals, herbicides or other possible pollutants in the soil fertility, arable layer, plough layer soil and crop samples, as well as the water quality test report of the irrigation water source. The process is complicated and requires a lot of information. After becoming an organic cotton field, the same inspection will be carried out every three years.

Ⅳ. Sustainable organic cotton harvesting

Before harvesting, they must receive an on-site inspection. The organic cotton inspector will check whether all harvesters are clean and whether a mixture of ordinary cotton, organic cotton, and excessive cotton remains on one side, and a separation zone shall be designated. It is better to harvest manually.

Ⅴ. Sustainable organic cotton ginning

The ginning factory must be checked for cleanliness before ginning and then can be processed. The ginning process must be isolated and prevent pollution, and the processing process must be recorded. The first bale of cotton processed must be isolated.

Ⅵ. Sustainable organic cotton storage

The storage warehouse must be qualified to distribute natural cotton organic products, and the organic cotton inspector must inspect the storage, and a complete transportation review report must be held.

Ⅶ. Sustainable organic cotton spinning and dyeing

All production areas for spinning sustainable organic cotton must be isolated from other varieties, and all production tools must be dedicated and cannot be mixed. Synthetic dyes must pass OKTEX100 certification. Plant dyes use natural plant dyes to realize environmentally friendly dyeing.

Ⅸ. Sustainable organic cotton weaving

The weaving area must be isolated from other regions, and the additives used in the finishing process must meet the OKTEX100 standard.
