Oerlikon Barmag offers a spinning system configuration in conjunction with the WinFors winder, designed especially for profitable mother yarn production.

The monofilaments produced from this are also extremely convincing in terms of their yarn quality, the company reports. The perfectly coordinated steps – from the spinning process all the way through to take-up – aim to ensure optimum results in the subsequent, downstream splitting process.

PET or PA process

When manufacturing mother yarn made from polyester (PET) or polyamide (PA) – the preliminary product for monofilaments – the later separation of the filaments must be monitored even during the spinning process. The yarn guide and take-up are attributed a central role: a good splitting process is dependent on the yarn path within the draw unit and the package build.

For this challenging PET or PA process, Oerlikon Barmag technology is said to provide a precise and gentle yarn handling. The spinnerets and quenching unit – whose design has been especially tailored to the requirements of mother yarn – prepare the evenly-cooled filaments for further processing by the system.

Splitting of the yarn

A special yarn guide in the system supports successful splitting of the yarn. For take-up, the yarn is transferred to the WinFors winder, which has been developed specifically for sensitive yarns. Its cam shaft guarantees excellent package build and stable edges for packages even in the case of the critical, high single dpf in mother yarn filaments, according to the manufacturer.

The precise and gentle yarn displacement of the cam shaft concept in conjunction with the tried-and-tested Oerlikon Barmag ribbon breaking process aims to ensure that the downstream splitting process is carried out efficiently and without any loss of yarn quality.

The Oerlikon Barmag FDY mother yarn concept has been optimized for the typical monofilament thicknesses of 15, 20 and 30 dpf and the associated mother yarn types such as 180 den F12, 240 den F12 and 360 den F12.

Rising market potential

Mother yarn is the term used to describe multifilaments that – following the spinning process – are split to create monofilament yarns. Their area of application is broad: in addition to drapes, mosquito nets, apparel (organza dresses, saris, etc.), monofilaments made from mother yarn are also used in the automobile sector, in items of luggage and in sports apparel (shoes).

Consequently, the demand for mother yarn is also increasing, the company reports. According to market insiders, there was a global growth potential of more than 10% last year alone. Particularly in India, the changed requirements of the textile further processing sector have resulted in increased demand for mother yarn.

According to Oerlikon, the two-stage process for manufacturing monofilaments deployed to date no longer provides the necessary profitability to secure commercial success.

Oerlikon Manmade Fibers

Oerlikon is a leading technology group supplying growth markets with market-leading technologies and services for surface solutions, systems for manufacturing manmade fibres, transmission systems and drive solutions, as well as prevacuum and high vacuum technologies and pumps and the corresponding accessories.

With its Oerlikon Barmag and Oerlikon Neumag brands, Oerlikon Manmade Fibers segment is the market leader for manmade fibre filament spinning systems, texturing machines, BCF systems, staple fibre systems and artificial turf systems and – as a service provider – offers engineering solutions for the entire textile value added chain.

With the expansion of the product range to include polycondensation systems and their key components, the company now caters to the entire process – from the monomer all the way through to the textured yarn. The primary Oerlikon Barmag markets are in Asia.
