B1. Demonstration of use of commercialmetal-free acid dyes on leather dyeing

Objective:

Obtain leathers dyed with commercial metal-free

acid dyes, which will be employed as a reference

for natural dyes evaluation

Tasks:– Selection of commercial metal-free acid dyes:

15 monochromatic samples + 10 combinated samples– Definition of the leather post-tanning process:

neutralization, retanning, fatliquoring and dyeing– Dyeing test at laboratory level– Evaluation of dyeing baths exhaustion by UV-V

Espectroscopy

Responsible: COLORTEX - INESCOP

B2. Demonstration of the quality features of dyed leather with metal-free acid dyes

Objective: Evaluate properties of commercial metal-free acid dyes in

the leather dyeing process, which will be employed as a reference for natural dyes properties evaluation

Tasks:

Responsible: COLORTEX - INESCOP

Dye fastness evaluation test: – to rubbing (wet and dry)– to light– to PVC migration– to water– to perspiration – to washing

Physical properties: – tensile strenght– elongation at break– tear strenght

C1. Monitoring on the environmental impact of acid dyes within leather manufacture

Objective: Quantify and evaluate the environmental impact of dyeing

residual bath which will be employed as a reference for natural dyes properties evaluation

Tasks:Chemical analysis of dyeing residual bath (Standard

Methods): − pH− Conductivity− COD− BOD− Biodegradability

Responsible: INESCOP
