Dilo to exhibit & run complete production line at ITMA

August 03, 2011 (Spain)

DiloGroup, the leading supplier of complete production lines for staple fibre web forming and consolidation, enjoys the same strong order inflow as during 2007 and 2008 with potential further increases. Dilo, therefore, looks forward with confidence to the ITMA show in Barcelona where we will present a complete nonwoven production line on a floor space of 1000 m².

The nonwoven staple fibre sector is still characterized by high demand and dynamic development in numerous application areas such as floor coverings, automotive interior linings, geotextiles and roofing material, filter media, synthetic leather, upholstery and mattress felts, thermal insulation, wipes for industry and household, special applications involving carbon fibre, glass and mineral fibres, technical and papermachine felts, medicine, hygiene and apparel.

For all these applications DiloGroup offers universal and special production lines which are adapted to the market and customer requirements. The research and development work applied to all line components, starting with fibre preparation including opening and blending, web forming and consolidation aims at fibre material savings, less energy consumption, increased production, higher efficiency and availability, improved ease of operation, reduction of downtime for maintenance, service and cleaning, improved web mass homogeneity and better felt surface quality.

In this context Dilo will exhibit and run a complete production line at the ITMA show which will comprise the following components:

DiloTemafa equipment for fibre preparation, i. e. opening and blending, consisting of 2 bale openers. One bale opener – type Baltromix – for high throughput, the other – type AlphaMix – for medium throughput capacity. The opened fibre flocks will be fed on a blending apron to a carding willow for further opening and blending and subsequently to a dosing opener and a fine opener which provide a constant fibre flow to the card feeding system controlled by a special control loop.

The dosing opener has a fine opening stage to deliver the optimum flock size for card feeding. The two-sided fibre infeed “Twinfeed” for the new MultiFeed card feeder is a distinctive feature. Double infeed and vibration effects on a suction infeed apron result in a very homogeneous feeding of the card and thus in a very homogeneous web mass.

The new MultiCard is a universal card which has been especially designed for operation in combination with a crosslapper. An optimum cost-performance ratio for this card has been realised by using computer-aided design and analytical research.

The MultiCard is characterized by extraordinary ease of maintenance and superior accessibility for cleaning and service work. The MultiCard shown at the ITMA has a suction and filter system designed by the “AirSystems Engineering” department of DiloTemafa. The sound insulation of this suction and filter unit is secured by “Temafa SoundControl”.

The MultiCard working with a double doffer and a pair of condenser rolls delivers a homogeneous double web to the subsequent high speed crosslapper type DLSC. The cross profile regulation system type “Profiline CV1A” for the crosslaid web pre-compensates possible thicker edges in the needling installation. Furthermore, the DiloLayer DLSC 25/35 with a laydown width of 3.5 m is equipped with the latest version of our “Webguide” system to allow the highest web infeed speeds up to 160 m/min. Subsequently, the web will be fed via a CBF batt feeding system with low draft to a universal 3.5 m wide needle loom DI-LOOM OD-II SB 35.

This production line is very economic for universal web forming and needling tasks characterized by a high potential for fibre savings due to a highly homogeneous web, low energy consumption, high availability due to reduced maintenance and cleaning, ease of operation and high felt quality. Although DiloGroup has a strong focus on complete production lines for web forming and needling, we also put special emphasis on the development of carding systems in large working widths exceeding 5 m and production speeds up to 400 m/min.

In this sector DiloSpinnbau has a leading position realizing high web uniformity and an optimum strength ratio in longitudinal and cross directions at low drafts. In this context the latest developments Twinflow and MultiFeed acting together as card feeding systems have to be mentioned as they deliver a homogeneous web matt by using the doubling effect and compaction. This results in a high infeed uniformity and web homogeneity especially in direct cards without subsequent crosslapper.

For numerous installations thermobonding, thermofusion or chemical treatments and drying equipment is requested. Especially in the production of geotextiles tenter frames are ideal to preserve width or for a definite stretching in width to give a balanced strength ratio in cross and machine directions. Aerodynamic web forming for highly voluminous insulation material also requires a double apron dryer for the thermofusion of low melt fibres.

DiloGroup has therefore initiated a close cooperation with Brückner, and we plan to install a double apron dryer in our Research Centre in Eberbach to run tests and demonstrate the suitability of the technological concepts. During the ITMA exhibition in Barcelona we therefore look forward to interesting discussions with our customers who plan to realize complete lines including thermal or chemical bonding.

In addition, we have a close cooperation with Messrs. ProCtec for electrical service tasks and they will be present on our booth. DiloGroup will provide extensive technical and technological information and as usual will display a large number of nonwoven fabrics which are either needled, thermobonded or water entangled. DiloSystem is the leading supplier of nonwoven production lines with more than 200 complete installations delivered worldwide since 1995.
