DiloGroup will present its portfolio of equipment to the nonwovens industry at the upcoming Techtextil India 2017 held in Mumbai from 13-15 September. The company will provide extensive information about production lines made in Germany and recent machine concepts from the DiloGroup companies DiloTemafa, DiloSpinnbau and DiloMachines.

DiloGroup enjoyed above-average order influx in all important markets for its machines and installations and had record turnovers in 2015 and 2016. According to the company, it developed its latest equipment components with a focus on improving web quality and uniformity applicable to all bonding processes, as well as operation efficiency of the needling line.

At the exhibition, DiloGroup, a leading group in the field of staple fibre nonwoven production lines, will talk about complete lines, presenting the latest developments. The company has recorded a strong demand for Dilo production lines, partly due to the increased requirements for needled nonwovens.

Staple fibre production line

Staple fibre production lines start with fibre preparation – opening and blending – from DiloTemafa, card feeding and cards from DiloSpinnbau and end with crosslappers and needlelooms from DiloMachines.

A Dilo line represents high productivity with high web quality. The four machine components are controlled by central drive and control stations in preparation for the modern requirements of crosslinking and smart production. Customized lines are engineered, manufactured, delivered and put into operation by DiloGroup.

Service and spare parts supply to support the high efficiency of Dilo nonwoven production lines is available worldwide. In addition to information about standard universal lines, the company will talk about the latest developments that aim to increase efficiency and productivity by the degree of automation.

One example of such innovations is the Vector 200, a new crosslapper by DiloMachines, which is the first crosslapping machine in the market with an infeed speed of over 200 m/min, the company reports.

Nonwovens for all applications

Dilo lines are used for the production of nonwovens for all applications including automotive products, floor coverings, synthetic leather, wipes, geotextiles, roofing and filtration. Considerable progress has been achieved in the processability of special fibres like virgin and recycled carbon fibres for composite materials. Compact special lines for product research, development and production with carbon fibres are available.

The company will discuss a close cooperation with needle manufacturer Groz-Beckert, which helped advance the development of the needle module technique and the intense needling of light weight nonwovens.

Numerous fields of application such as filter media, geotextiles, roofing material, floor coverings, other technical textiles and composites require needled nonwovens with high low-load resistance. This is generally achieved by using reinforcing meshs / grids. The Dilo HyperTex installation produces a reinforcing scrim which is fed between two needlefelts which are then joined together by a Hyperpunch needleloom.

The aperture size of this scrim can be varied up to 20 x 20 mm and production speed is up to 40 m/min. The HyperTex installation in a working width of 2.5 m is available for presentation and trials in the Dilo Textile Research Centre in Eberbach, Germany.

Carding systems

DiloGroup will also inform about carding systems of wide working width and high web speed for water entanglement lines. For this important branch of nonwovens production, lines generally have a working width of about 3.8 m and medium web speeds of around 200 m/min. DiloSystems offers special carding systems with working widths exceeding 5 m and resultant web speeds of more than 400 m/min after water entanglement and drying.

“Reduced draft between card doffing and winding are essential to achieve a high web uniformity and an acceptable strength ratio in machine direction to cross direction (MD:CD),” the company explains. “DiloSpinnbau sets the standard for high productivity with the random roll technology and for best felt homogeneity by low draft. DiloGroup is very successful with these fibre preparation and carding systems in nonwoven production lines with high productivity and quality requirements.”
