In 1911, after ten years of experimenting with the seeds of various cotton plants, Fermin Tangüis an agriculturist cultivated "Tangüis Cotton".

Tangüis was able to develop a seed which produced superior cotton plant resistant to diseases. It is characterized by its incredibly soft, long, and uniform fibres. Highly absorbent, Tanguis cotton will retain 24-27 times its own weight in moisture. Garments made with Tanguis cotton are said to "breathe," as the fibre absorbs and releases perspiration quickly.

Tangüis cotton, as it became known, is the variety preferred by the Peruvian national textile industry. 75% of all the Peruvian cotton production is now Tangüis cotton, both for domestic use and export.
