In the textile industry, enormous amounts of fabric are discarded. With technological development, today we can recycle materials and reinsert them in the production cycle, as is the case of recycled cotton.
Recycled cotton is produced, as the name indicates, by recycling pre- or post-consumer cotton waste. First, pre-consumer fabrics, that is fabric remnants from the manufacture of cotton goods, are recycled.
In practice, pre-consumer waste is easier to recycle, since the products already consumed often have other raw materials mixed in, such as polyester, viscose, or even accessories like buttons.
Therefore, it is fundamental that when selecting products, a careful analysis of the composition label is done.
After the correct selection of the residues, they are separated by color and type, and then mechanically crushed, without the addition of chemicals, dyes, or water, giving rise to simple cotton fibers.
Next, the fibers are refined and subjected to a carding and trimming process to obtain the desired thickness and then spun again. Thus, to obtain a yarn similar to that of traditional cotton, the fiber goes through a narrowing process.
However, the result of this recycling process is that the fibers are short and difficult to spin. This means that the recycled cotton has to be mixed with virgin fibers so that the yarn can withstand the entire production process.
Finally, once the fibers are transformed into a new yarn, the fabric is produced that has a more handmade look due to the mixture of shades from the different reuses, which means that each batch of recycled cotton has a different color.
That said, recycled cotton is sustainable for several reasons:
01. Its process is based on recycling surplus or waste from the textile industry;
02. Its process does not require water, which, compared to conventional cotton, results in a drastic reduction in water consumption;
03. This process does not use harmful products, unlike conventional cotton, which uses about 16% of insecticides and 7% of pesticides in the world;
04. In terms of energy, recycled cotton has lower energy consumption;
05. The use of recycled cotton contributes to the reduction of greenhouse gas emissions and CO2.
