Oerlikon Manmade Fibres, the leading supplier of nonwoven technologies, will be showcasing at the Techtextil India trade fair for technical textiles and nonwovens in Mumbai, India, that will take place from 3-5 October.

With its Barmag and Neumag brands, Oerlikon Manmade Fibres will be showcasing solutions for the efficient production of innovative yarns for very special applications. Furthermore, the public will be presented with new nonwoven production methods.

The company believes that there is a room for growth in the nonwovens sector, offering the complete spunbond process from a single source – from polymer granulate, as an alternative to staple fibre and glass fibre products.

The company's in-house nonwovens expert, Dr Ingo Mählmann said there is a considerable trend towards using spunbonds, as these nonwovens are less expensive to manufacture, partially as a result of the single-stage production process.

According to Dr Mählmann, it is the construction sector that is increasingly using spunbonds. The examples include bitumen roofing and construction nonwovens for reinforcement and drainage. He also commented on the Oerlikon spinning machines: “In terms of the system width, our machines are not just able to produce up to four times more material. They also help cut operating costs for energy and maintenance and save on operating staff costs.”

In addition to industrial spunbond systems, Oerlikon Neumag also develops stand-alone mono-component and bi-component meltblown systems, the benefits of which will be presented at the  Techtextil Symposium by Ed McNally, Sales Director Nonwovens.

Two-cop WinOro-S 2 winder

The demand for high-tenacity specialty fibres such as aramids, UHMWPE and carbon fibres is steadily growing, the company reports.

The WinOro, one of the winders from Oerlikon Barmag's range, has been designed especially for winding viscose yarns, fibres made from aramids and polyethylene or similar materials. Depending on the design, the automatic precision take-up head for specialty yarns winds – at a speed of up to 1,000 m/min – baler twine of up to 25,000 denier, PVC-coated multifilament yarn for various industrial applications and also textured artificial turf filaments.

Specialty yarns used in special applications also demand special processing. The automatic WinOro precision winder – which also comes in a two-cop version is said to fulfil this requirement. According to Oerlikon, the two-cop WinOro-S 2 saves 45% of energy consumption compared to the single-cop automatic winder.

The two-cop WinOro-S 2 is also said to offer flexibility with regards to the yarns to be wound with three optional strokes: 2x120 mm, 2x190 mm and 2x225 mm, which is expected to allow yarn manufacturers to retain the tube dimension if they decide to switch from a single-cop winder to the two-cop WinOro.

Two-cop WinTrax winder

WinTrax is a two-cop winder from Oerlikon Barmag, developed especially for manufacturing carbon fibres. It is used for products that have to unite low weights with extreme tenacities.

Carbon fibre-reinforced plastics are deployed in the aerospace industry, in wind power systems, in the automobile sector, in safety technology and also in high-end sports equipment such as racing bicycles, tennis rackets, skis and boats among other areas.

According to the company, WinTrax offers a simultaneously perfect package build and identical running length. Furthermore, the packages that the new WinTrax-A 2cop produces have a diameter of up to 310 mm, resulting in higher package weights. These said to shorten the tooling times and hence considerably reduce the time and costs for manufacturing compound materials, eliminating the waste.
