Dyed continuous filament yarns aiming to push into high-visibility aerospace and transport markets

Moulinage Du Solier : 04 October, 2013  (New Product)
Moulinage du Solier specialises in preparing thread based on technical materials, particularly with regard to electromagnetic protection and thread colouring. One of the eight colours in the Nexocolor range (fluorescent yellow) complies with EN471, the high-visibility standard, with regard to colour and hold, despite the difficulties of fading due to ultraviolet rays.
Dyed continuous filament yarns aiming to push into high-visibility aerospace and transport markets
Nexocolor is a fireproof filament yarn the colour of Nomex . This range depends on a proprietary meta-aramid treatment process. “Some firms already know how to dye fibres, but none of them is capable of doing it with continuous filament, which we can”, declares Pierre-Yves Suchail. “Some competitors outside Europe also have such skills, but these involve the use of chemicals banned in Europe. Moulinage du Solier is different and only uses chemicals that comply with the REACH standard, which governs the registration, evaluation, authorisation and restriction on chemical substances”.
The firm is also currently conducting a study to obtain the aerospace standard – requiring a hold of 160 hours at 200C – and even to exceed this by achieving a hold of 160 hours at a temperature of 250C! Obtaining this standard would allow the firm to expand its applications into aerospace and transport. These are sectors where coloured thread is very much in demand for the sake of traceability in electrical wiring looms and for making assembly work easier. 
"Penetrating the transport market could lead us to incorporate cut-resistant threads, which would complement the intrinsic fireproof properties of meta-aramid thread. We are also working on two big projects to diversify our product range, which should lead to new activities by the end of the year," says Suchail.
Elsewhere, the NO’EMI range of wave-shielding thread combines textile and metal for custom-designed electromagnetic shielding (fabrics, braids or mesh). “The fibres are mixed with textiles to improve their electrical resistance, but especially to make them lighter”, says Pierre-Yves Suchail. The first developments of these wave-shielding threads were mainly intended for the public in the form of curtains and other everyday objects. Now Moulinage du Solier is putting its shielding threads in a wider range of applications in the health industry. “A lot more applications are possible”, adds Suchail. “We are currently working on setting up a project in partnership to expand the applications into wall coverings.”
