The Dyer-Bot is the first open source and ecological dyeing machine project. The Dyer-Bot will dye textile with recycled materials such as avocado rinds, tea, unsold flowers or local plants for making customized colors for fashion collections


The project

The Dyer-Bot :


Our project consists of making collections using only natural dyes from recycled materials (avocado rinds, coffee, tea, unsold flowers...) and local plants (woad, rubia, reseda...).


We want to make a pigment exctracting and textile dyeing machine. The machine will be ecological and its conception and making will be Open Source and shared through




Why ?


Environmental impact of standard textile dyeing is tremendous. Unfortunately there is no technology made for dyeing natural fibers ecologically and no open-source dyeing machine available for designers. This infographic illustrate synthetic dyeing impact and the alternative solution we want to create.

This project will help growing local economies world wide and will complete two others open source textile technology projects : OpenSource Loom and the electric fiber spinning wheel. The dyer-bot will be useful for :





-Developping countries




Rosa Tapioca :


We are a young parisian fashion brand producing in France and using ecological textiles. We want to go deeper into sustainable development by creating our own natural colors. We work with a Textile Engineer and we have been studying natural dyes for years. You can discover our collection on our website, The first naturally dyed collection will be out in 2013.




The Dyer-Bot:  


We want to make a machine for extracting pigments and dyeing textile so we can dye our own collection on a small scale.


The dyer-bot consist of an inox Vat with an heating belt, a circulation pump and a filter. It will be monitored by a computer.  The conception and making of the machine will be published on



The dyer-bot will dye garments, fabrics and yarns. There is no equivalent machine existing in the industry and it will take natural dyeing further. Its has three main advantages as compared to other textile dyeing machine.


1- Cheaper: the dyer bot will cost less than every other industrial dyeing machine suitable for natural dyeing. Moreover, free recycler dyeing materials (tea, avocado rinds, unsold flowers) can be easily used with it.


2- Easy-to-use : the machine is tought to be used by people with no knowledge in dyeing so they can make their own colors. The process will be made as simple as possible and published on


3- Grow local and ecological economy : it will allow to reduce transportation and geographical concentration of toxic industries.

 : Open-Source exchange



The dyer-bot will be made as an open source hardware, in the first french FabLab (the FacLab of cercy-pontoise university).

On we will share natural dyeing recipes and how-to guides for making and using the dyer bot.

Why fund it?

We ask only for half of our budget on this crowdfunding platform :


Dyeing Vat 499€

Circulation Pump : 262€

Vat heating belt :  318€

Assembling : 130€

Textile dyes solidity testing and certification : 1115€

First web-base Open-Source dyeing community : 56€

Making an efficient network for upcycling amoung shops, industires and farmers : 650€

Arduino micro-controler : 20€


Total : 3050 €


We ask only for half of this amount, and considering the financial fees, we need to obtain at least 1600€.


Every additional amount will be used for

- Developping our dyeing plant garden

- Developping Open-Source textile technologies in order to grow a new kind of local and ecological textile industry world wide.


ROSA TAPIOCA est une marque de création textile et vestimentaire créée en 2008 à Paris. Sensible, imaginative et responsable, la créatrice souhaite conserver l'idée d'une industrie à dimension humaine. Les collections sont fabriquées en France et déjà distribuées à l'international.

FAQ Questions about the project

+ Do the colors stick to clothes after washing ?

Yes. In order to prove it we will work with a textile lab that will test and certificate our clothes. They will be fast to washing, light and sweating. Our clothes will conform to the norms NF EN ISO 105 - C06, B02 and E04.

+ Is it really ecological ?

Yes. We don't only do vegetable dyeing, we use natural mordants, local plants and recycled materials. Moreover we will do composting with our wastes and reuses dye bath as much as possible.

+ What is "Open Source Hardware" ? Why is it good ?

Open Source Hardware consist of making and sharing freely a technology allowing everyone in the world to replicate and improve it instead of exploiting it alone.

This is a real revolution for every industry.

Open Source projects are particularly appropriate for crowdfunding as what everyone can funds goes back to everyone through technology sharing.

+ What are FabLabs ?

FabLab are open fabrication laboratory. They follow the principle of Open Source and collaborative technology innovation.
We are working with the first French FabLab : the FacLab of Cergy-Pontoise university.

These small creation and fabrication space spread very quickly around the world and they grow local economy as well as they democratize technological innovation.

+ When will the dyer-bot be ready ?

The dyer-bot will be ready in September 2012.

Rosa Tapioca collection will be ecologically dyed from 2013.

+ Where can we find your collections ?

One our website

We have anonline shop and we are in several shop in France and around the world.

You can subscribe to the dye-lab newsletter and like Rosa Tapioca facebook page and discover our naturally dyed collection as soon as they are available.
