As the automotive sector shows signs of recovery, DiloGroup reports that investments in nonwoven production lines for the manufacture of glass fibre-reinforced thermobonded structural parts for interiors are underway.

DiloGroup has already received a repeat order from Zhejiang Huajiang Science and Technology based in Hangzhou, China, for a complete web-forming and needling line to process blends of glass and polypropylene (PP) fibre.

It is equipped with a DiloTemafa fibre preparation system adapted to the special requirements for processing the glass fibre, and its homogeneous blending with PP.

A component-dependent Baltromix blending system using highly precise weighing pans provides accurately dosed fibre material on the collecting apron, which is further opened and blended in a carding willow

In many installations DiloTemafa also provides equipment for the recycling of quality fibre derived from the whole process which is sucked off at many stations in the fibre preparation and web-forming system, in order to save material. Installations for fibre transport and for fibre recycling within a line, together with re-opened edge trim material from a needling station and for dedusting the machines by a drum filter or bag filter station, can also be specifically engineered.

The efficiency of a line processing mineral fibres largely depends on the efficiency in dedusting of all machine components – from bale opening through to needling. Solutions for this demanding task are part of the expertise of DiloSystems as the general contractor.

At the card, the so-called “fancy roller” is part of a double-doffer system allowing the web to be formed without leaving too much fibre within the card clothing wire. Dilo works closely with a range of customers and card wire suppliers to provide an optimum wire system for processing the demanding range of mineral fibres.

In the needleloom, this expertise in prolonging the intervals for cleaning stops is vital and blowing nozzles which clean the perforated plates, stripper and bed plates are integrated. The dust exhaust is separated at a filter station.

The majority of Dilo lines today include an elaborate air system and the necessary components for fibre, dust transport and recycled fibres transportation.
