What is different from other ecological dyeing?

Many companies propose so-called “natural” dyed yarns, but:


Some of them employ extracts instead of herbs together with some chemical substances to enhance the final color


Some others use not entirely natural dyeing techniques: a compromise between a chemical and natural process

A Real 100% Natural dyeing technique

NATURALE TECHNOLOGY uses exclusive protocols prepared with 212 different plants, herbs, roots, flowers and tree bark: a real 100% Natural Dyeing technique.

What are the benefits for the people and the environment?

That’s why at Tintoria di Quaregna, we’re guiding a real change into the market to produce the next generation products through natural dyeing.


Reduce chemicals and toxic substances  by using only herbs and natural elements


Reduce waste and emissions
by recycling production rejects as fertilizers in farming or biomass for renewable energy production


Counteract climate change
by reducing CO2 emissions into the atmosphere, replacing the use of textile synthetic dyes derived from petroleum with CO2 absorbing vegetable farming 


Reduce pollution
because the colors, obtained by natural dyeing process NATURALE are biodegradable
