Dilo

At the forthcoming joint exhibition of ITMA Asia and CITME in Shanghai from June 22 –26,2010 the DiloGroup will exhibit latest textile samples and product development results from the Dilo Textile Research Centres to provide information about complete line installations comprising machines for bale opening and blending from DiloTemafa, carding or aerodynamic web forming from DiloSpinnbau, crosslapping and needling from DiloMachines.

In addition to needling other bonding technologies such as water entangling, thermo and chemical bonding are available from DiloSystems in close co-operation with well-known leading partners. Therefore, the full range of web forming and consolidation technologies is offered for complete line installations worldwide.

Dilo will provide general information about all kind of nonwovens. Special emphasis will be laid on new equipment components to improve web quality and uniformity applicable to all bonding processes.

DiloTemafa shows the latest design of its web edge opener in a working width of 0.5 m. This machine reopens the web edges which are cut after needling and feeds them back into the manufacturing process, thus saving fibre costs.

Furthermore, DiloTemafa will inform about the DON dosing opener which serves as a linkbetween the opening/blending operation and card feeder. This ensures that fibre flow to thisfeeder is both consistent and continuous.

DiloSpinnbau provides information about the newly developed MultiFeed card feeder which is available in working widths exceeding 5 m. This unit is equipped with a twin fibre delivery system called “Twinflow” in the upper chamber which provides further fibre mixing. A two roll opening stage allows fibre into the lower chamber for further compaction by mechanical means and air movement derived from the permeable delivery apron.

Such a unit can deliver more than 400 kg/m/hr of 1.7 dtex fibres with a cross direction evenness CV of 2 – 3 immediately prior to the card. Changeover times with this MultiFeed system are fast thus reducing downtime and web reprocessing requirements. Machine direction evenness is controlled by a weighbelt scale linked to the card infeed. MultiFeed can be used with all DiloSpinnbau card types in crosslapping applications or with high speed cards in series for hydroentanglement web formation.

This card range has been recently extended by the MultiCard which offers roller infeed, a breast cylinder with three worker/stripper pairs and a 1500 mm main cylinder with a further five roller pairs. This is a double doffer system with the possible activation of condenser rolls for heavier webs. Such a card will handle the full range of fibre fineness and length with a web speed potential up to 150 m/min and offers an economic solution for cross laid nonwoven production.

DiloMachines offers both vertical (HL series) and horizontal (DL series) crosslappers with the former arrangement providing infeed speeds up to 200 m/min. The Dilo DL lappers operate in an infeed speed range of 80 – 160 m/min depending on application and specific model used. In addition to high infeed speeds new apron arrangements have been used to give high layering precision based on excellent web control. These machines are available in working widths up to 16 m for papermachine clothing applications.

The further development of needle looms continues. Elliptical and circular needle beam movements are used to control drafts in the needling zone and also provide high speed felt production in the weight range from 30 – 80 g/m².

DORNIER

With optimistic expectations Lindauer DORNIER GmbH looks ahead towards the upcoming ITMA Asia + CITME 2010 taking place form June 22 – 26, 2010 for the second time in Shanghai. Expectations are very optimistic thanks to the worldwide recovery of the economic situation.

In hall E4 stand no B01 DORNIER will present a PS rapier weaving machine, proving once again their expertise for the production of technical textiles. During the exhibition different versions of conveyor belt fabrics will be woven on this extremely sturdy machine with heavy reed beat up and positive controlled center transfer.

The versatile system family
The DORNIER weaving machine system family, composed of rapier and air-jet weaving machines, offers all necessary requirements for the production of technical textiles. The gentle filling process with very low tension peaks enables the processing of extremely subtle yarns. During open shed insertion the yarn is tightly held by the positively controlled rapier head and gently inserted into the shed without any guiding elements.
Both machines can hold an extremely high or low warp tension which enables to weave very dense fabrics such as conveyor belts or aramid fabrics as well as open mesh structures of glass or also carbon.

DORNIER PX – the lean machine
The weaver of apparel fabrics or home textiles will be informed about a very advantageous solution: the PX rapier weaving machine.
Especially in the area of decorative and upholstery fabrics, the PX serves the market requirements in the best possible way.
It is an all-round machine with standardised reliable DORNIER technology. With the PX, the versatile possibilities of the DORNIER rapier weaving machine have been refined down to the essential requirements of the apparel and home textiles weaver: the established machine widths of 190 and 220
