Spunlacing with high pressure technology
Spunlacing by high-pressure technology joins natural or man-made fibres into mats with specific properties. The mats of fibres produced in this way are basic materials for many everyday consumer goods such as paper tissues, napkin inserts, filter paper, face masks or clothing and automotive fabrics.
The high-pressure water required is supplied by URACA pumps, whose operating pressure and flow rate can be precisely adjusted by means of speed regulation. Over many years, these energy-efficient displacement pumps have proven their worth all over the world.
In the first step of fiber spunlacing, natural or man-made fibers are laid out to a fleece and prepared for the process. Fibers may be, for example, cotton fibers, viscose fibers or mixed fibers. High-pressure water join the fibers in a special component of the spunlacing system. Nozzle beams supplied with high pressure water produce the required water jets. Processed drinking water or demineralized water can be used as circulation medium in circulation operation. After the fibers are joined, the fleece is dried. The finished mats of fibers can have very different properties. These mats form the basis for many utility and hygiene goods.
