WP 2: Selection of the textile substrates and chemicals

In the BISCOL, project will be focused on the dyeing industry and a new dyeing

process for the bioconversion of raw materials into competitive eco‐friendly final 

products.

To reach this scope different expertise's partners of consortium will be combined

WP2 is the first technological work package which lead to decisions concerning target 

dyes to biosynthesized, textile fibers to dye and auxiliaries to optimize dyeing process

Duration: M1 to M8

Task 2.1 – Selection of the textile substratesAccording to market values and to the data available at the end‐users (KING) three 

textile substrate to be used as target products within BISCOL were selected. The 

following parameters are considered for the selection of the textile fibers

1. amount of fibers that has to be treated in the last 2 years  

2. market data about fiber production in Europe and/or in the Global Market.

Conclusion

We selected;

1. wool as first fiber to be used in BISCOL project. As wool is one of the most used fiber 

in Prato district, and as its environmental impact is lower than other fiber

2. cotton as second fiber because it is the most important and used natural fiber

3. a man‐made fiber, because it is reported that it has a lower environmental impact 

than cotton due to the lack of cultivation step

Task 2.2 – Selection of the dyestuff and auxiliaries

For the selection of the dyes (The different dyestuff classes – such as reactive dyes; 

direct dyes; acid dyes; etc. – ) used for Textile Industry ,the following factors were 

important

1. Used by the end‐users in the last two year  

2. Their EU  market values for the selection of the classes for the bio‐synthetized  dyes. 

3. Dye fixation levels

4. Mutagenic, carcinogenic, and allergenic effects 

5. International labour cost in the textile industry

Task 2.2 – Selection of the dyestuff and auxiliaries

To overcome many dyeing problems  the dyeing auxiliaries were investigated

Leveling agents to improve the solubilisation of the dyestuffs

1. Polyacrylic acid for co‐polymers 

2. Surfactants.

Non‐ionic

Anionic

Cationic

Amphoteric

A report including all the details concerning the chemical structure of the selected

chemicals (both dyestuffs and auxiliaries) and it will be used as guide book for the

production of the bio‐dyes.

Task 2.2 – Selection of the dyestuff and auxiliaries

For the selected dyestuffs, a list of auxiliaries were produced and the role of each 

chemicals were defined in order to provide the consortium with a complete 

description of the dyeing processes. 

Exhaustion dyeing from an aqueous bath with dyes are considered in the BISCOL 

framework.

An Acid dyeing on WOOL will be important in the project
