Tanguis Cotton
Fiber — one of 29 in the glossary
A Peruvian cotton variety developed in the early twentieth century by Fermín Tangüis, grown mainly in the Cañete valley south of Lima and along Peru's central coast. Its fibre is longer and thicker than ordinary upland cotton and unusually resistant to breaking, and the plant was bred for disease resistance and low water requirements — which is why it rescued Peruvian cotton growing after blight devastated the earlier crop.
Bred out of a crisis
Peruvian cotton growing was devastated by wilt disease in the early twentieth century. Fermín Tangüis spent years selecting plants that survived it, and the variety that resulted carries his name.
It is disease-resistant and needs relatively little water, which is what made it viable on the Peruvian coast.
That origin story is why Tanguis is a point of national pride in Peru rather than simply a commodity grade.
Longer and thicker, not finer
Tanguis fibre runs roughly 29 to 33 mm, longer than ordinary upland cotton, and it is notably thick and strong for its length.
That is a different proposition from Pima, which is longer and finer. Pima gives smoothness and lustre; Tanguis gives body and resilience.
The fibre's resistance to breaking makes it well suited to fabrics that need to hold up rather than to feel silky.
Where you meet it
In heavier Peruvian knitwear and in blends, often alongside Pima, where the two contribute different things.
It is less marketed than Pima because the qualities it brings are less immediately obvious in a shop.
On a spec sheet it is a genuine signal of Peruvian origin, which Pima alone is not — Pima is grown in several countries.
Common questions
- What is Tanguis cotton?
- A Peruvian cotton variety bred by Fermín Tangüis, grown mainly in the Cañete valley. Its fibre is longer and thicker than upland cotton and resists breaking.
- Is Tanguis the same as Pima?
- No. Both are Peruvian-grown, but Pima is extra-long staple and fine, giving smoothness and lustre. Tanguis is thicker and stronger, giving body and resilience.
- Why was Tanguis cotton developed?
- To survive the wilt disease that devastated Peruvian cotton in the early twentieth century. It is disease-resistant and needs relatively little water.
