In particular, BW Converting’s Baldwin TexCoat® G4 precision spray technology – in combination with advanced Archroma finishing formulations and Monforts MONTEX stenters and MONFORTEX shrinking ranges and related technologies – is pushing the envelope in new standards for sustainable and long-lasting clean productivity.

Functionality

Michael Schuhmann, Global Marketing Finishing at Archroma Textile Effects, explained that typical key functions provided in textile finishing include sweat and odor control, water repellence and UV resistance. Softeners are primarily applied to make fabrics more comfortable while other finishes provide reduced crease formation for easy-care properties. The traditional padding or exhaust techniques for applying these finishes require huge volumes of water and energy intensive drying.

Spray application, by contrast, requires much less water due to drastically reduced ‘pick up’ – the amount of liquid that a fabric absorbs and retains, determining how much finishing agent remains in the fabric. This also enables significantly faster drying, making process speeds of up to 100 metres per minute possible, depending on the fabric.

“As the global fashion brands commit to reducing their emissions, the textile processing industry must respond by adopting safer chemistries with resource-saving processes such as spray application,” Schuhmann said.

Precision

Rick Stanford, Vice President Global Business Development for Textiles at BW Converting, explained that at the core of the Baldwin TexCoat G4 technology are precision valves that were originally developed for the offset printing industry and have been refined over the past 40 years through more than 40,000 installations globally.

“These enable extremely precise spray flows which are controlled by proprietary software algorithms,” he said.

Over 100 TexCoat G4 units have been installed worldwide and all three companies are enjoying notable success with bed sheeting manufacturers in Pakistan.

“Our first TexCoat G4 in Pakistan was installed in Spring of 2024 for a manufacturer using Archroma chemistry and a ten-chamber Monforts MONTEX stenter,” Stanford explained. “When using the padder at this mill, the pickup rate was 65% and with TexCoat G4 we were able to reduce that to 27%. As a result, the customer was able to increase the MONTEX speed from 60 metres a minute to 100 metres a minute, while also reducing the operating temperature in the stenter. We have subsequently sold 30 TexCoat G4 units in Pakistan, driven primarily by the system’s proven productivity and efficiency gains.”

Energy savings

“A BW Converting Baldwin TexCoat G4 unit is now installed at the Monforts Advanced Technology Center (ATC) for trials and fully complementing spray finishing operations are our multiple energy saving innovations,” added Saskia Kuhlen, Monforts Engineer for Textile Technologies. “MONTEX stenters are equipped with the TwinAir air volume regulation system as well as the TwinTherm system for temperature control and feature CADstreamE variable nozzles. These features enable full adjustment to a specific fabric width for either higher operational speeds or lower electrical energy. A further benefit is the150-mm wide advanced insulation system inside the stenter frame”.

Further Monforts modules for optimizing processes include the coaTTex unit for the knife coating of paste and foam application and the EcoApplicator, a kiss-coating technology for the indirect application of finishes on one or both sides of a fabric, with a stenter production speed up to 100m/min. Both can be integrated into existing lines.

The Monforts Energy Tower and EcoBooster are meanwhile modules for air/air heat exchanging, for heat recovery from the exhaust flow of thermal systems. They can also be retrofitted to existing stenter frames, relaxation dryers, infrared pre-dryers and hotflues.

“We continue to explore the best heating options for every customer, with optimised combinations in order to make our lines as energy efficient as possible,” Kuhlen said. “We have also been deeply investigating the potential of green hydrogen as a further option for the future.”

BW Converting’s Baldwin TexChroma™

In response to a big market demand, the three technology partners are now turning their attention to the dyeing process.

At ITMA Asia + CITME in Singapore, from October 28-31, they will introduce the resource-saving combination of THERMEX continuous dyeing ranges with the new BW Converting Baldwin TexChroma™ spray dyeing system.

“We are excited to introduce the Baldwin TexChroma because spray dyeing is the future,” said Stanford. “We’ve been cautious about providing details on TexChroma too early, but now we’re ready and look forward to outlining its benefits in Singapore with interested customers. We will also be installing a TexChroma unit on a THERMEX line at the Monforts ATC in 2026.”
