From the Sector

INDA, the Association of the Nonwoven Fabrics Industry, announced the three finalists for the World of Wipes Innovation Award®. The Award will be presented at the annual World of Wipes® (WOW) International Conference, June 17-20, at the Hyatt Regency Minneapolis in Minneapolis, Minnesota.

The three products vying for this Award are multi-purpose cleaning wipes from Kimberly-Clark Professional, a bio-binder technology from OrganoClick, and facial care wipes from Rockline Industries. The winner will be announced on Thursday morning, June 20th.

The three companies competing for the Award are:

• Scott® Xtreme Multi-Purpose Cleaning Wipes by Kimberly-Clark Professional:
  Scott® Xtreme Multi-Purpose Cleaning Wipes are great for tackling extreme cleaning tasks, like removing oil, grease, grime, paint, adhesives, caulk, and more, yet are gentle enough to clean hands.  Featuring a patented citrus cleaning solution, the dual-action cleaning fabric incorporates a textured side to increase scrubbing action for cleaning tough soils and a smooth side for wiping surfaces clean.  Scott® Xtreme Multi-Purpose Cleaning Wipes are truly a must-have for any DIY job and cleaning on-the-go.
• OC-Biobinder® Lily1450 by OrganoClick:
  OC-Biobinder® represents a series of bio-based and biodegradable binders intended for the nonwoven and paper industry. They are produced from renewable raw materials and residual streams from the food industry and replace traditional fossil-based plastic binders. OC-Biobinder® is available with many different properties adapted to the production of home compostable nonwoven materials such as premium napkins, table cloths and wet wipes.
• Facial Care Wipe with Glycine Amino Acid Complex by Rockline Industries:
  Rockline’s development of a facial wipe product containing a unique multifunctional complex of two glycines, a phospholipid compound and a blend of glycols allows for a multitude of skincare benefits as well as providing a self-preserving system for cellulosic nonwovens. Believed to be the first application of glycines in a wet wipe formulation, the product offers improved skin smoothness, elasticity, and hydration alongside an anti-aging claim.

INDA’s Technical Advisory Board selected the finalists based on the creativity, uniqueness, and technical sophistication employed in finding novel ways to expand the utilization of nonwovens. Categories considered for the award were wipes-related raw materials, roll goods, converting, packaging, active ingredients, binders, additives, and end-use products.

The 2023 World of Wipes Innovation Award winner was Indorama Ventures and Polymateria for their Nonwoven Wipe Using Biotransformation Technology. This innovative spunlace wipe utilized advanced biotransformation technology developed jointly by Indorama Ventures and Polymateria. Meeting the BSI PAS 9017 specification, this wipe in the event it becomes fugitive, and exposed to heat, sunlight, air and moisture will transform into a harmless, bioavailable wax at its end-of-life, eliminating microplastic pollution. Compatible with mechanical recycling and combatting 'fugitive' waste, this wipe represents a significant leap towards eco-friendly, sustainable nonwoven hygiene products.

Fibres, fabrics, epoxy resins and adhesives from Sicomin have been used by Grand Largue Composites (GLC) to construct the first Class40 racing yacht to feature a significant quantity of flax-fibre reinforcements.
The yacht, called Crosscall, won the Class40 World Championships in June 2022 and is a prototype of the new Lift V2 design by Marc Lombard, one of the leading naval architects in this field.

Class40 is one of the most competitive fleets in yacht racing. The hulls of Class40 yachts must be light in weight, strong and stiff, and durable in the most extreme of conditions. Furthermore, to keep costs down, they cannot be reinforced with carbon fibres. The quality and reliability of the resins used for the infusion and lamination of the hulls are therefore of paramount importance.

Crosscall's cockpit was designed to be effectively non-structural, with the mainsheet, which can generate huge shock loads, supported separately. This would allow the cockpit to be made from a hybrid biaxial fabric comprising 50% flax fibres. Other parts of the boat that incorporate flax fibre include the tunnel, the engine cover, the ballast tanks and the cap. The rest of the boat is reinforced with 100% glass-fibre fabrics.

To help it realise this ambitious design, GLC, an infusion specialist, turned to its long-time material supplier, Sicomin. The hull was moulded and infused in one piece and the deck – including the hybrid flax-fibre cockpit – was also infused as a single part. The internal structure was then laminated into the hull by hand before the hull and deck were finally bonded together.

The infusion resin selected was Sicomin’s SR 1710, a high-modulus structural epoxy. Designed specifically for use in infusion and injection processes, it has exceptionally low viscosity and its low-reactivity hardener makes it suitable for the production of large parts. Composites components made from SR 1710 possess high interlaminar shear-strength and the resin retains its mechanical properties in wet environments.

Sicomin’s low-toxicity SR 8200 was used to laminate the internal structures onto the skin of the hull. Ideal for hand laminating, this system includes a choice of hardeners with a wide range of reactivities, which makes it equally suitable for making large or small parts. The hull and deck were joined together with Sicomin’s Isobond SR 7100, which demonstrates high fatigue strength and is very resistant to microcracking.

An epoxy bonding primer – called Undercoat EP 215 HB+ and supplied by Sicomin’s sister company, Map Yachting – was applied to the moulds first to make demoulding easier. It also serves as an undercoat in the polyurethane exterior paint system that is used instead of gelcoat to protect the epoxy hull from UV damage.

Since the launch of Crosscall, GLC has started building a second Lift V2 Class40 and a third one is now planned, both for which Sicomin will supply the materials.
