Halley Stevensons: Unique waxed cotton finishing with new Monforts line

Monforts has installed and commissioned a new Montex finishing range at the Baltic Works of Halley Stevensons in Dundee, Scotland, to further boost the weatherproofing specialist’s highly flexible operations.

The range, with a working width of two metres, was built at the Montex assembly plant in Austria and consists of a Montex®Coat coating unit in knife execution for paste and foam coating and a Montex 8500 6F stenter.

Founded in 1864, Halley Stevensons has amassed unique technical know-how and manufacturing experience in the art of waxed cotton for weatherproofed fabrics and is able to provide international orders in custom colours and finishes to very low minimum quantities where required. The company exports worldwide and its premium brand customers include Belstaff, Barbours, Filson and J.Crew.

The range has replaced one of the company’s older stenter/coating lines and has already enabled Halley Stevensons to recreate various products with lower coating applications at higher speeds than was previously possible.

Waxed cotton was originally developed by sailors in the early 15th century when Scottish North Sea herring fleets began treating flax sailcloth with fish oils and grease in an attempt to waterproof their sails. Remnants of these sails were used by the sailors as capes to withstand the high winds and sea spray.

By the mid 1850s, sailcloth was being treated with linseed oil, but while initially highly effective, it would yellow and stiffen through weathering over time and eventually lose its waterproofing qualities.

In the years that followed, various treatments were applied to cottons in an attempt to find the most effective weatherproofing solution, and the combination of densely-woven cotton impregnated with a paraffin waxed coating proved most successful. For over 150 years, Halley Stevensons created many different variations of both woven constructions and finishing treatments and now supplies thousands of metres of waxed cotton every year, with each roll produced to custom specifications.

“The beauty of waxed cotton is its durability and longevity,” says Managing Director James Campbell. “The fabrics are breathable, with the wax adjusting to ambient temperatures to be softer and more breathable in warm weather and stiffer and more wind proof in cold conditions.”
While traditional waxes are petroleum or paraffin based, Halley Stevensons has always been comfortable about using a waste product from industry and reusing it to make products that last a lifetime.  

“We are always exploring different finishing techniques and one of our most popular finishes is our hybrid aero – an emulsified blend of waxes,” Campbell says. “This fabric is water repellent but has little wax in the mixture so the handle is much drier to touch than the traditional wet waxes.”

The company has also recently launched a new 100% plant-based wax – Ever Wax Olive – consisting of a blend of olive oil, rape seed and castor bean with comparable water repellence to petroleum and a far better rating than other natural waxes which have come before it.

“The high tradition of skills and fabric innovation imposed by our original guildsmen is still our benchmark standard of honest workmanship today,” Managing Director James Campbell concludes “We use responsibly sourced cotton fabrics and processes that are gentle to the product and low impact to the environment. Our dyeing methods use very low levels of water and our waxes are simply heated up for application and cooled down to store when not in use, meaning no waste discharges. Now, with this new Monforts line, we are also achieving running speeds two-to-three times faster than with the older stenter, combined with less gas usage. It’s proved a great partnership.”

Reifenhäuser Cast Sheet Coating presents new Ultrathin Coating process at ICE Europe

Reifenhäuser Cast Sheet Coating - specialists for cast film, sheet extrusion and extrusion coating lines - will showcase a new production process for cost-effective film/nonwoven composites with an exceptionally low grammage at ICE (International Converting Exhibition) Europe. The leading international trade show for paper, film, and foil conversion and processing will be held at Messe München (Munich trade fair center) from March 15-17, 2022.

The Covid-19 pandemic and current supply shortages have exposed the dependence of companies on global supply chains. This situation is both a warning signal and an opportunity to boost and reorganize the local production of semi-finished products from the ground up. Reifenhäuser Cast Sheet Coating has now developed a trend-setting production process termed Ultrathin Coating, in particular for the sector of medical protective clothing. The process will permit customers to produce particularly lightweight film/nonwoven composites with greater cost efficiency and, as a result, more competitively. The patent-pending process has several advantages: It cuts film grammage by 66%; material consumption in the overall composite is reduced by 28%; and it slashes costs by up to 34% compared to conventional semi-finished products. Significant cost savings are achieved in various ways, for example, by replacing hotmelt adhesives, which reduces line maintenance to a great extent at the same time.

Mark Borutta, Sales & Marketing Specialist bei Reifenhäuser Cast Sheet Coating, erklärt: „Wir erleben derzeit einen nachhaltig wachsenden Mehrbedarf für medizinische Schutzbekleidung verbunden mit einer Rückholstrategie für lokale Produktionskapazitäten. Vor diesem Hintergrund erzielen Produzenten mit ‚Ultrathin Coating‘ einen schnellen Return on Invest und hohe Profitabilität – auch bei einer Produktion innerhalb Europas.“ Die Vlies-erfahrene Schwesterfirma Reifenhäuser Reicofil –führender Hersteller von Vliesstoffanlagen – hat die Entwicklung unterstützt.

Mark Borutta, Sales & Marketing specialist at Reifenhäuser Cast Sheet Coating, explains: "We are currently experiencing a sustained increase in demand for medical protective clothing combined with a return strategy for local production capacity. Against this backdrop, producers achieve a fast return on investment and high profitability with Ultrathin Coating - even when production is based in Europe." The sister company, Reifenhäuser Reicofil, an experienced and global leading manufacturer of nonwoven lines, provided their support to the development.

Even if manufacturers already produce medical protective clothing and prefer to handle the coating process internally in the future instead of importing the necessary composites, it is worthwhile to set up an in-house production facility. In either case, the investment in Ultrathin Coating usually pays for itself in less than 12 months. The lower material input also reduces the consumption of fossil raw materials and this in turn responds to the increased demand for more sustainable products.
