1 INSTYTUT WLOKIEN CHEMICZNYCH INSTITUTE OF CHEMICAL FIBRES COST 628, Bucharest Meeting, 17 – 18th March’05 COST 628 WG –1 Meeting Bucharest 17th March, Presentation: Proecological manufacture, use and utilization of fibres and textiles Presented by: Ms. Beata Obrebska Mr. Alojzy Urbanowski Institute of Chemcial Fibres, Lodz, Poland

2 INSTYTUT WLOKIEN CHEMICZNYCH INSTITUTE OF CHEMICAL FIBRES COST 628, Bucharest Meeting, 17 – 18th March’05 COST 628 WG –1 Project conducted within COST 628 sponsored from national funds. Granted by Ministry of Science and Information Technology Partner: INSTITUTE OF CHEMICAL FIBRES Title of project: Proecological manufacture, use and utilization of fibres and textiles. Two subjects of the project: TASK 1:Environment-friendly processing of cellulose pulp and the manufacture of cellulosic fibres. TASK 2:Chemical recycle of polyester and polyamide textile waste.

4 INSTYTUT WLOKIEN CHEMICZNYCH INSTITUTE OF CHEMICAL FIBRES COST 628, Bucharest Meeting, 17 – 18th March’05 Environment –friendly processing of cellulose pulp. Code name: CELSOL Concept: Replace the burdon - some viscose process with a modern biotechnological technique.

5 INSTYTUT WLOKIEN CHEMICZNYCH INSTITUTE OF CHEMICAL FIBRES COST 628, Bucharest Meeting, 17 – 18th March’05 COST 628 Environment –friendly processing of cellulose pulp and the manufacture of cellulosic fibres. Processes commercially employed to produce cellulosic fibres: Viscose – about 90% of all cellulosic fibres NNMO (Lyocell) – new technique Cupro – rarely applied Acetate – mainly for cigarette filters
