At this year's ITMA the company will be presenting the following new developments:
-    The CPB dyeing center for knitwear and woven fabrics - salt-free cold dyeing process.
-    The Tempacta washing steamer for knitted fabrics with freshwater supply that is controlled by the degree of contamination.
-    The Trikoflex drum washing machine that is available up to a working width of 5,400 mm. In addition, a specially developed expander roller for sensitive fabrics will be exhibited.
-    Multipad - the new development for complex impregnation tasks on woven fabrics and knitwear with electronically monitored, automatic lubrication.

Salt-free dyeing of woven fabrics and knitwear

Salt-free dyeing without the use of energy is only possible using the cold pad batch (CPB) dyeing process. This process is also becoming increasingly popular in tropical and subtropical regions, which is reason enough to adapt the CPB systems even more effectively to the climatic conditions. The heart of our CPB system is the Benninger Küsters Dypad, which will also be presented at the ITMA. Here the S-roller technology, enables an even dyeing result across the entire fabric width.

Contamination-dependent washing

The Tempacta washing steamer has been especially developed for all low-tension washing processes and is mainly used for diffusion washing (fastness washing). The unit has a consistent counter-flow water supply. Online measurement of the degree of contamination regulates the necessary amount of fresh water in order to guarantee the lowest possible water and energy consumption and ensure a high reproducibility of the washing result.

Tension-free and crease-free washing of textiles up to 5,400mm

The Trikoflex drum washing compartment has a very high mechanical washing efficiency thanks to the double drum technology and the front and back washing technology. Crease-free fabric transport is guaranteed, even with sensitive fabric. In addition, a cylindrical expanding roller has been developed for particularly sensitive textiles for wet and steam applications. The washing compartment is rounded off with the Hydrovac vacuum-water extraction system. Since each reaction process is followed by a washing process in wet finishing, 70% of the energy consumption is incurred during washing. For this reason, the washing compartments are insulated so that up to 50% of the radiated energy can be saved here.

New impregnation aggregate

The newly-developed Multipad is an absolute highlight with regard to flexible impregnation tasks. The unit is equipped with an optional double impregnation feature and is suitable both for heavy denim articles and for very light knitwear. One of the special applications is over-dyeing and mercerizing of denim. The Multipad is also used for cold bleaching and pre-treatment of knitwear.

IoT - networked and informed at all times

The topic of the “internet of things” (IoT) is also becoming increasingly important in the textile machinery industry. True to the principle "trust is good, control is better", the important operating parameters of the Benninger systems are continuously monitored in a closed control circuit. Deviations are detected and corrected immediately.
Particularly quality-critical parameters are forwarded to those responsible by means of modern IoT technologies and an alarm is sounded in the event of limit value violations. A good example of this is the central bearing lubrication on the Dyepad: The critical lever bearings of the padder are permanently lubricated, malfunctions are reported and the lubricant is automatically replenished. Another example is online monitoring of the air-conditioned electrical circuit cabinets. A newly revised maintenance manager provides information about the maintenance status of the system at any time and generates a recommendation as well as a schedule for the next maintenance cycle. Another example of modern process monitoring is the newly-developed online measurement of the degree of contamination of the washing water and the resulting optimization of water consumption.
To give customers an overview of their production facility at all times, the established management information system Ben-iData has been further developed. This allows the customer to query all important machine data, the maintenance status and the ecological footprint of the current production batch at any time and from any place. Furthermore, an electronic ticket system for service assistance has been developed, which transmits diagnostic data at the time of the event to the Teleservice team in the main facility at the customer's request.
