Toabo Corporation, Sotoh Co. LTD., and Moriyasu Dye Works Co. Ltd., have jointly worked to establish a pilot plant for a new chlorine free treatment named LIFE FIBRE ECO-FRIENDLY TREATMENT (LIFE FIBRE EFT) in Ichinomiya, the heart of the Japanese wool industry. This new treatment will be launched at the Woolmark stand at ISPO held in Munich on the 5th of February 2017.

 

‘We will be offering this technology to international top makers to develop Zero AOX wool products to the global markets in the near future’, says Toshiya Inoue of Life Fibre Company.

 

LIFE FIBRE EFT is based on Interfacial Polymerization which enables to encapsulate the native hydrophobic surface of wool fibre with polyamide, that prevent wool fibres from entangling, provides shrink proof attributes to products.

 

A solution of Diacid Chloride in a water-immiscible solvent, contacts with an aqueous solution of a Diamine, by which, Polymer is formed at the interface of the two liquid phases.

 

‘This treatment is new and unique. It is commercially applicable, enabling continuous processing, although the technology itself has long since been established’, he says.

 

Toshiya Inoue further comments that the benefits of LIFE FIBRE EFT include several unique elements such as superior shrink resist functionality without removing scales unlike other treatments such as Super-wash, Enzyme and Plasma treatments, which maintains wool’s native hydrophobic attributes. ‘It is remarkable for off-scaling of those treatments damages the fibre a lot and often leads to yellowing and deterioration in fibre strength’.

 

This is also significant under the circumstances that environmental regulations are becoming more and more stringent around the globe especially in Europe.

 

This new processing requires less water and less electricity, as it can be treated with a second order reaction and it only requires water temperature of 40 degrees in centigrade maximum.

 

Interfacial Polymerization comprises the molecular binding, thus, this polymer encapsulation, in comparison with Chlorine Hercosett, generates better durability, and furthermore, products developed with LIFE FIBRE EFT are not only machine-washable compliant to IWS TM31 – ISO 6330-1984, but they also endure the application of Tetrachloroethylene that is commonly used in the dry cleaning system and are often tolerant against enzyme detergents.

 

He adds that ‘the treatment can theoretically be engaged with any forms of intermediate products such as top sliver, yarn, and knitted and woven fabrics. LIFE FIBRE EFT technology is able to bring possibility in brilliant white colour and light shades with durable colour fastness to light by mixing pigment dye-stuff and ultraviolet absorber in the Polyamide polymerized on the preserved scales.

 

‘The treatment is proven to be applicable to other fibres regardless either they are man-made or natural fibres, which enables to add functionality such as UV protection and FIR by blending substances to the polymer’, concludes Toshiya Inoue.
