Requirements for Organic Cotton Raw Materials, Printing and Dyeing, and Finished Products

The ordinary cotton T-shirts we wear on our bodies or the cotton sheets we sleep on may have thousands of chemical substances remaining on them. Because organic cotton has no chemical residues in its production and manufacturing process, its advent is entirely in line with people's pursuit of green and environmentally friendly fibres. Organic cotton feels warm and soft to the touch and makes people think utterly close to nature. This kind of zero-distance contact with nature can release stress and nourish the soul. The production of organic cotton reflects people's pursuit of quality of life and health, and to a certain extent, promotes the development of organic cotton.

Organic cotton material is also called ecological cotton or bio-cotton. It is a new type of cotton produced by the United States in the mid-1980s. The production and processing of organic cotton materials have been stipulated. The requirements for raw materials, printing and dyeing, finished products, etc., are as follows.

Ⅰ. Raw material requirements for organic cotton products

1. The fibre raw materials of organic cotton textiles should be 100% organic raw materials.

2. In processing raw materials into fibres, minimize the impact on the environment.

3. Non-textile raw materials in textiles should not cause harm to the environment and humans in the process of production, use and waste disposal.

4. The formula of organic cotton materials shall not include pentachlorobenzoic acid, tetrachlorophenol and polychlorinated biphenyls.

Ⅱ. Printing and dyeing requirements for organic cotton products

1. Try to use biological sources or fuels extracted from plants.

2. Try to use mineral dyes that do not contain heavy metals and only use natural printing and dyeing thickeners when printing and dyeing.

3.  Only use easily biodegradable softeners.

4. It is forbidden to use substances containing organic halogen compounds in sewage to clean printing and dyeing equipment.

5. The content of heavy metals in the dye shall not exceed the required index.

Ⅲ. Technical requirements for organic cotton products

1. The auxiliary materials (such as decorations, buttons, zippers, etc.) must use materials that are not harmful to the environment and use natural organic cotton materials.

2. During the processing of finished products (such as sand washing and water washing), harmful additives to the human body and the environment must not be used.

Organic cotton must be certified in all links, including land, climate, seeds, cultivation, planting, harvesting, storage and transportation, spinning, weaving, and garment making (including related items, equipment, and auxiliaries). There are many international organizations engaged in the formulation and certification of organic cotton standards. The global organic cotton product standard is a globally recognized leading processing standard for textiles made from organic fibres. The concept of organic cotton is of great significance to promote human health, protect the ecological environment, and meet people's consumer demand for green and environmentally friendly clothing, and has broad development prospects!
