Dyeing and the finishing step is one the most polluting and water-intensive procedures during garment production. Synthetic dyes used and discharged into the waterway is harmful to the aquatic ecosystem and toxicity could also build up within the human body along the food chain. Ziran is concerned with the toxicity implications of conventional dyes, and proceeds to using the Xiang yun sha silk in its pieces. Xiang yun sha silk has been hand-made by skilled artisans in southern China for over 500 years and its production process involves 'coating the silk with iron-rich mud, dyeing it in vegetable juice, and baking it in the sun'. With the Xiang yun sha silk, Ziran is able to produce all natural, non-toxic pieces for its consumers without any harmful chemicals.

According to the Ellen MacArthur Foundation, the fashion industry uses around 93 billion cubic meters of water annually. This is enough to fill 37 million Olympic swimming pools. Dyeing, which goes along with finishing, is one the most polluting and water-intensive procedures during clothes production.

Even for natural or organic fibers, if they are dyed with toxic azo dyes and toxic finishing chemicals, they can cause similar pollution when the fibers shed during the washing cycles and enter the waterway in both the production and consumption phases.

These dyes could be harmful to both the environment and humans. To the environment, chemical-laden wastewater dumped into nearby waterways during production could reduce plants' ability to carry out photosynthesis, and disrupt the aquatic ecosystem. Once in the wastewater, dyeing chemicals are difficult to remove. To humans, the toxicity could build up along the food chain and hence, the human body as well. Some dyes could also be carcinogenic, and their particles could cleave, producing potentially dangerous aromatic amines that could be harmful upon skin contact.

Xiang yun sha silk, which translates to 'perfumed cloud clothing', has been hand-made by skilled artisans in southern China for over 500 years. The silk is proudly described as 'an emblem of the [Chinese] cultural heritage, Daoist philosophy, and the magical workings of Mother Nature.' Every yard of silk is different and produced in small batches. The production process involves 'coating the silk with iron-rich mud, dyeing it in vegetable juice, and baking it in the sun'. Hence, its production is time-consuming and weather dependent.

Ziran hopes to bring all natural, non-toxic, organic clothing to consumers without any chemicals by using the Xiang yun sha silk in its pieces while preserving the unique Chinese culture.

Ziran is the first and only company in the US using Xiang yun sha silk. With the silk from the Chinese artisans, the pieces are hand cut and sewn in Los Angeles. From there, all natural, non-toxic, organic pieces without any harmful chemicals are produced, allowing Ziran to go with its mission to ' [weave] tradition into the modern world and [lead] a new generation to live the Ziran way: natural, spontaneous, and free.'
