From the Sector

The full potential of advanced coating and finishing technologies for the production of technical textiles will be outlined by Monforts specialists which takes place in Atlanta, Georgia, in May.

The company and its US representative PSP Marketing, of Charlotte, North Carolina, will be part of the VDMA German Pavilion at the show, at stand 3231 within the Georgia World Congress Center.

A wide range of technical fabrics is now being successfully created with MontexCoat coating units in comination with Montex stenters, including tents, tarpaulins and awnings, black-out roller blinds and sail cloth, automotive interior fabrics and medical disposables.

Full PVC coatings, pigment dyeing or minimal application surface and low penetration treatments can all be carried out with the extremely versatile system. Solvent coatings in explosion-proof conditions, knife coating, roller coating and screen printing are further options and the MontexCoat has been engineered to enable users to switch quickly from one fabric run to the next without compromising on the economical use of energy or raw materials.

“There has already been terrific interest in the MontexCoat and the range of different techniques it enables and we’re far from exhausting its potential uses,” says Achim Gesser, Monforts Area Sales Manager who will be at the show in Atlanta. “For companies who don’t need such flexibility, the economical coaTTex unit is exclusively dedicated to air knife and knife-over-roller coating.

“At our ATC in Mönchengladbach, Germany, however, a MontexCoat unit has been integrated into a full Montex technical textiles pilot line, on which our customers can run trials of new fabrics and finishing formulations in widths of up to 1.8 metres. This line has been engineered to provide the ultimate in precision coating and finishing in industrial-scale trials.”

To fully demonstrate what’s possible, the Montex line at the ATC is able to treat materials not only at temperatures of up to 320°C, but apply separate coatings on the two sides of certain materials at different temperatures, within a single pass through the machine. To achieve this, the first two chambers of the stenter are fitted with TwinTherm burners for individual top/bottom heating. A temperature differential of up to 60°C can be achieved between the upper and lower nozzles within the chamber, depending on the treatment parameters.

“There are many applications where employing two separate temperature treatments is beneficial, such as floorcoverings – where the textile face fabric is treated at one temperature and the rubber backing at another – as well as PVC flooring employing chemical foams, black-out roller blinds with heavy backings or PTFE-coated filter materials,” Gesser explains.

Another key feature of the technical textiles line at the ATC is the Montex stenter’s special stretching device which is capable of pulling ten tons in length and ten tons in width – a huge amount per square metre of fabric and necessary in the production of materials such as woven or 3D knits for high temperature filter media.

Monforts also offers the special T-max grease-free stenter chain for high temperature treatments up to 320°C, at machine speeds up to 100m/min and transverse tension up to 2,500 N/m with the benefits of no maintenance and no grease marks on fabric.

“Technical textiles are extremely diverse in their end-use applications but the needs of the manufacturers of very different materials are still uniform in many respects,” says Gesser. “European-built Montex stenters provide maximum finishing efficiency and many of our customers are operating them 24 hours a day over seamless shifts.”

Existing customers include manufacturers in the fields of home textiles, geotextiles and automotive fabrics, as well as functional materials and dedicated Montex lines have also been supplied to producers of airbags, flame retardant barrier fabrics and spacer fabrics.

“Techtextil North America is a very important show for us because technical textiles are a key pillar of our production programme,” Gesser concludes. “North America is one of our major markets and we are looking forward to reconnecting with existing and potentially new customers at this always-vibrant show.”

Leading knit solutions provider SHIMA SEIKI MFG., LTD. of Wakayama, Japan, together with its U.S. subsidiary SHIMA SEIKI U.S.A. INC., will participate in the Techtextil North America exhibition in Atlanta, Georgia, U.S.A. this month. Under the theme “techKNITians—Technical Engineered Knit Applications,” the company will display its latest computerized flat knitting machines and computer graphic design system technology, aimed at promoting knitted applications in the field of technical textiles.

Pioneered by SHIMA SEIKI, WHOLEGARMENT® knitting technology is capable of producing knitted items in their entirety without the need for sewing, and allows complex 3D forms to be knit such as car seat covers and interior furnishings. Selective compression allows control over placement and amount of pressure for various compression wear in sports and medical applications. The seam-free nature of WHOLEGARMENT® also ensures continuity of yarn, allowing functional yarns such as conductive yarns to wrap around the entire body without interruption, for applications in smart garments and wearable technology. Demonstrating the latest in WHOLEGARMENT® knitting technology at Techtextil will be the flagship MACH2XS machine that features the company’s original SlideNeedle™ on 4 needle beds and patented springloaded full-time sinker system. Capable of WHOLEGARMENT® knitting in all-needles, MACH2XS offers great flexibility for knitting high-quality WHOLEGARMENT® products with a seemingly endless variety of knit patterns at very high speed and efficiency, all while minimizing dependence upon labor-intensive sewing and linking. At Techtextil North America MACH2XS will be shown knitting a seam-free balaclava in one entire piece using fire-resistant yarn.

Also shown will be the SWG091N2 compact WHOLEGARMENT® knitting machine, also featuring SlideNeedle™ technology. Capable of producing small knitted items from safety gloves and compression socks to more sophisticated industrial applications such as tubular shields and harnesses, SWG091N2 offers unique solutions for the automotive, aerospace, sports, medical, safety, outdoor and other markets by knitting items in 3D without seams. SWG091N2 will be knitting fire-resistant gloves at Techtextil North America. SHIMA SEIKI’s SDS®-ONE APEX4 3D design system will also be available for demonstrations in design and simulation of various technical textiles. Of particular interest is its ultra-realistic simulation capability that realizes virtual sampling. When numerous variations must be evaluated before arriving at a final design, virtual product samples can be used to streamline the decision-making process by minimizing the enormous amount of time and cost normally associated with producing actual physical samples for each variation. The sustainability factor is also undeniable considering the amount of material normally gone to waste in the sampling stage.

The next edition of Techtextil North America will take place in Atlanta from May 17^nd to 19^th.  At Atlanta ACIMIT, the Association of Italian Textile Machinery Manufacturers, and Italian Trade Agency organize an Italian Pavilion, where 17 Italian machinery manufacturers involved in the production of machines for technical textiles will show their innovative solutions.

ACIMIT members exhibiting in the Italian Pavilion are: 4M Plants, Aeris, Arioli, Computer House, Fadis, Flainox, Guarneri Technology, Ima, Kairos Engineering, Mcs, Ramina, Siltex, Stalam, Testa, Willy.

Non-contact precision spray technology enhances productivity, sustainability and process control

Baldwin Technology Company Inc. has announced that it will showcase the TexCoat G4 non-contact precision spray fabric finishing system at the Techtextil North America tradeshow, held from May 12 to 14, 2020, in Atlanta (booth #3048).

With extensive sustainability benefits, unprecedented tracking and process control, and industry 4.0 integration, the TexCoat G4 provides consistently high-quality fabric finishing, with no chemistry waste, as well as minimal water and energy consumption. 

Baldwin’s innovative non-contact spray technology eliminates chemistry dilution in wet-on-wet processes. The TexCoat G4 consistently and uniformly sprays chemistry across the fabric surface and applies it only where needed, on one or both sides of the fabric. Customers can expect no bath contamination during the finishing process, as well as minimal downtime during changeovers, which are made easy with recipe management that includes automated chemistry and coverage selection.

The TexCoat G4 also enhances sustainability by wasting no chemistry during color, fabric or chemistry changeovers, and because only the required chemistry volume is applied to the fabric, wet pick-up levels can be reduced by up to 50 percent—leading to 50 percent less water and energy consumption. Furthermore, in single-side applications, drying steps can be eliminated for various textiles, including those that are back-coated and laminated, thereby streamlining and simplifying the production process.
