Save Money and Energy in the Processing of Denim Fabrics by Spraying
In the conventional padding process, fabrics are impregnated with a finishing liquor and squeezed to a certain residual moisture. Afterwards, the moisture (water) needs to get removed from the textiles through an energy-intensive drying process. In cooperation with WEKO, the leading producer of non-contact minimum application systems, and Lilienweiß GmbH, a German service and finishing company for denim and garments, we have developed an energy efficient and gentle production process for the finishing of denim yard goods, with which you can save money.
By using the WEKO Fluid Application System (WFA) you can finish textiles with an exactly dosed, non-contact method, thus considerably reducing your production costs. Instead of a liquor pick-up of 60 to 100 % in the padding process, the WFA process applies only 15 to 30 % of liquor to the fabric. With this sustainable, ecological and economical process, you can save up to 60 % of textile auxiliaries and chemicals. Furthermore, you can reduce your energy costs for drying by up to 70 %.
The Advantages of the Sustainable WFA Process
The WEKO Fluid Application Process (WFA Process) offers the following advantages:
- Optimization of the finishing process
- Ensuring reproducible quality
- Saving auxiliaries and chemicals
- Reduction of energy expenses
Contact-Free Finishing of Textile Fabrics
The WEKO Fluid Application System (WFA system) is mounted in the finishing department at the infeed or outfeed of the stenter. With the exactly dosed minimum application, drying times are reduced and production speed can be significantly increased. Besides, there is no squeezing required on the padder. This eliminates additional mechanical stress to the fabric.
During finishing, the liquor comes in contact with the fabric. For this reason, the WEKO liquor does not need to be drained off. It can be reused without any problems for the next production batch. The results are conserved chemicals and textile auxiliaries, reduced costs and protection of the environment.
