Dilo will Attend Techtextil with Its Innovative Technologies

The production of very light-weight hygiene products on water-entanglement lines requires a high web quality and a low area weight. To realize high productivity with these demands, Dilo has resumed and revised the principle of the camel-back crosslapper. The kinematic solution of the Hyperlayer lays down the web gently and precisely even with a small number of layers.

As the web is guided through the complete laydown process on both sides, highest production speeds (web infeed speeds up to 200 m/min), precise edges and a minimum of draft can be realized depending on the fibres used.

Nonwoven filter media consist of a sandwich structure which combines the filtration characteristics of felts with the high strength of yarns or filaments. The HyperTex process allows the production of reinforced felts online and eliminates an additional stage for producing the scrim.

DILO-“Hypertex” installation, consisting of a yarn laydown unit from Messrs. Ontec and subsequent needling, provides highly efficient inline production of reinforced needlefelts. With this system, scrim structures and preneedled weblayers can be needled together at speeds up to 20 m/min. In the HyperTex process Dilo combines a scrim fabric machine of Messrs. OnTec with a Hyperpunch needleloom.

The structure derives its strength from needling scrim, upper and bottom felt together. The high efficiency in regard to fibre and energy consumption and the low space requirement are further significant advantages of this technology.

The new needle arrangement “8000 X” ensures homogeneous distribution of needle penetrations in the felt over a wide range of advance/stroke. The results are considered a breakthrough for improved surface qualities, particularly for car interiors.

Techtextil is one of the most important exhibitions in the field of nonwovens and Dilo has participated since its inception in 1986.
