Objective
The prototype machine manufactured is built on the basis of a LAJTOS industrial jigger fitted with the latest features in terms of unwind speed adjustment and fabric tension adjustment. The whole operation of the machine is managed by a programmable automated system: programmed injection of dyes and auxiliaries, fabric unwinding, and management of microwave power and operating safety devices. The main energy supply is by indirect steam by coil immersed in the liquor. Additional supply by microwaves represents an installed power of up to 30 kW produced by power generators situated on the roof of the machine and distributed over the length of the product to be processed. The microwave energy is confined within the processing area by devices which eliminate microwave leaks outside--chokes on the doors as well as on all sensitive parts.
The most salient advantages have been obtained on viscose dyeing (direct dyes) and cotton dyeing (high temperature reactive dyes). For viscose dyeing, there is a reduction in the overall dyeing time of around 20%. The results obtained in cotton dyeing occur on all important items for the dyer:
increase of dye yields by about 10 points (from 70% to 80%);
reduction of pollution by the dye from 25-30%;
improved levelness;
salt consumption lowered by 25%;
dyeing time shortened by 30 min.
During the last ten years JIT (just in Time) has been introduced throughout the textile industry. The finishing industry is now moving towards the use of equipment such as the jigger wich allows greater flexibility of production for small quantities. The jigger has benefited from a number of improvements in recent years (programming and more precise control of dyebath composition) although the basic principles have remained unchanged.
This project proposes a radical evolution in the jigger process by using a microwave energy in addition to traditional heating techniques wich should give considerable improvements in efficiency. The project is based on a study done in 1990 / 1992 with the financial support of Electricité De France, using a dyeing jigger at the laboratory scale wich clearly demonstrated that such a system was not only capable of cutting treatment time by 50%, but also improved dye yields by 20-30% irrespective of the type of material treated.
The aim of this project is the production by the proposers of an industrial system using the microwave process and its installation at an european textile finisher, in order to evaluate and demonstrate the efficiency of the process at an industrial scale. This pilot system will be fitted with control instrumentation set up to allow accurate measurement of energy used and will take ecological considerations into account within the context of the preparation and dyeing process using microwave assistance. Comparisons will be made with the traditional methods used on the same machine with a particular attention to the product quality evaluation.
