Continous biopretreatment of cellulosic fibers

Objective

In this project a sustainable technology will be developed for the continuous open-width pretreatment of cellulosic fibres by means of enzymatic scouring and bleaching. Enzymes systems will be developed in order to realize the bio-scouring and biobleaching. Equipment will be the development of the enzyme systems for bioscouring and biobleaching, the development of batch processes for bioscouring and bioleaching and the realization of the continuous open-width bio-pretreatment process. The biopretreatment process will lead to a decrease in the use of water, chemicals and energy by 50-80%, contributing to the competitiveness of the European textile industry. By lower processing temperatures and the absence of hazardous chemicals, the working conditions in the textile industry will greatly improve.
-2 characterised enzyme systems for bioscouring: an alkaline pectate lyase from B. pumilus and two acidic polygalacturonases from S. rolfsii,
-a laccase from T. hirsuta for bleaching purposes has been identified,
-a bioscouring process for both batch and continuous production ,
-a developed enzyme-based continuous operating, integrated desizing and scouring process,
-an engineered and constructed machine on lab/pilot plant level for operating the above mentioned integrated process,
-a biobleaching process for on-top-of whiteness generation or for reduction of the required hydrogen peroxide concentration (the process is invalid for use as direct bleaching method yet),
-the knowledge that the indirect bleaching system via glucose oxdiase is not competative economically,
-identification of an enzyme-based route for the removal of seed coat fragments. The process is not ready for implementation yet.
