From the Sector

Kornit Digital LTD. announced to unveil its new Smart Curing and Rapid SizeShifter solutions at TecStyle Visions 2023. Kornit Smart Curing is an intelligent and adaptive solution significantly streamlining curing processes while delivering high-quality results. Additionally, the introduction of Rapid SizeShifter eliminates time-consuming direct-to-garment pallet changes typically required to address disparate applications.

Kornit’s new energy-efficient Smart Curing solutions include Orion for mid-level production, and Titan for higher-capacity volumes – both optimized for compatibility with Kornit Atlas MAX systems and based on field-proven solutions from the acquisition of Tesoma. These highly efficient curing systems sync production and finishing for an end-to-end process that reduces both energy consumption and total cost of ownership (TCO). Kornit’s Rapid SizeShifter for Atlas MAX is an adjustable pallet that quickly adapts to disparate application requirements – reducing costly downtime associated with pallet changes and streamlining production for accelerated time-to-market.

New ideas were exchanged, brainstormed, and discussed freely at members’ booths at the Swiss Textile Machinery Pavilion during the recent Techtextil in Frankfurt. “Customers and researchers met Swiss textile machinery companies to explore the possibility of the not-yet-invented. “We regard our Pavilion as the place where future innovations catch a spark,” says Cornelia Buchwalder, Secretary General of the Swiss Textile Machinery Association. Further developments in the field of hybrid yarns were a hot topic. One example of this involves producing a yarn which has all the typical characteristics and advantages of carbon – but which also prioritizes careful use of resources, combining carbon fibres with thermoplastics.

Technical textiles cover a vast range of applications, and it’s still growing thanks to intensive research by specialist institutes and universities. Many members of the Swiss Textile Machinery Association maintain long-standing partnership with such bodies. Innovations are often joint efforts.

Feel-good technical fabrics
Some technical textiles feel like a second skin. A well-known example is activewear from the ‘sport tech’ field. Activewear includes breathable clothing, usually consisting of a three-layer-laminate: an inner lining, a breathable membrane in the center, and an outer fabric. The challenge is to bond the individual layers without losing breathability or softness, while meeting technical requirements such as resistance to a number of wash cycles.

Bonding solutions meeting top quality requirements, as well as ambitious standards for environmental protection and sustainability, were reinvented by the Cavitec brand from the Santex Rimar Group. This company’s hotmelt technology uses one-component polymers applied to textiles in a hot, molten state. Bonding based on hotmelts is both water- and solvent-free. Drying and exhaust air cleaning are not necessary, which is an ecological advantage. Energy consumption is also significantly lower. Cavitec hotmelt technology is also developed for laminated medical protection fabrics which are safe, high-quality and sustainable. These fabrics can be washed, sterilized, and used again.   

A second skin with added value is the result of Jakob Müller Group’s cooperation with an institute for an established outdoor fashion brand. They have devised a heating mat applied as an inner jacket. Outdoor gear with a heated inlay offers the wearer a comfortable feeling even in a cold climate. The heating mat is particularly light, breathable, flexible and adjustable to three temperature levels.

Fabrics with these advantages are now possible thanks to multi direct weaving (MDW) technology from the Jakob Müller Group. A lacquer-insulated heating strand is inserted into the base textile as a ‘meander’ using MDW technology. The technology is offered with both label weaving machines and the latest generation of ribbon weaving machines. The textile pocket calculator is another MDW based future-oriented application developed in cooperation with a textile research institute.

Safety and health
Life-saving reliability is a must for vehicle airbags. They have to fulfil high security aspects, and must remain inflated for several seconds when an accident occurs. Airbags made of flat-woven fabric – cut and seamed – can show weakness at seams during the inflation phase. Latest Jacquard technology by Stäubli enables one-piece-woven (OPW) airbags to be produced, creating shape and structure in a single process. The final product is an airbag consisting of a sealed cushion with woven seams. OPW airbag weaving reduces the number of production steps, and increases the security aspects.
Another big advantage of Stäubli’s new weaving technology is the flexibility in formats required in today’s mid- and upper-range cars, where lateral protection (in the seat or in the roof over the door) has become standard and is designed in line with the car shape. Safe airbags are woven on modern high-speed weaving machines. The warp material, the variety of fabric patterns, and the importance of precisely shaped airbags require the use of a robust and reliable Jacquard machine.

A revolution for orthopaedic patients is a knitting machine from Steiger Participations, which uses compressive yarns developed to meet the needs of the specific health market. This machine model was exclusively designed for production with inlaid elastic yarns and offers optimum performance with guaranteed final product quality.

In the orthopaedic field, many Steiger flat knitting machines have already been operating as automatic, custom-made production systems. For example, the dimensions of an injured limb are taken by the doctor and fed into a web-based application. The doctor selects the compression class in the various sections of the item and a data file created by the software automatically applies a preconfigured program. With no human intervention required, the program is generated and produced on the machine, precisely matching the patient’s dimensions. Each product is different, and generally available within 48 hours.

• Based on high-tech finishing, responsible materials and certified partnerships
• With multicolored flock, zero water printing, chenille and metallic effects, the company is at the forefront in establishing a responsible lace supply chain

Legend has it that a sailor brought his beloved a seaweed from distant seas as a gift. The woman, wanting to preserve its beauty, replicated the design and holes with needle and thread. And so lace was born. Since that moment, lace has lived within the walls of churches and castles, visited race tracks and catwalks, changing shape and color according to seasons and times.

Among the companies involved in writing a new chapter in the history of lace, Iluna Group definitely stands out. Founded in 1970 from an idea of its founder Luigi Annovazzi, over the years Iluna has responded to the challenges posed by the market in terms of technology and sustainability.

Since 2017 Iluna has been using only sustainable and certified ROICA™ stretch yarns from the ROICA Eco-Smart™ family, while the percentage of sustainable references has risen from 3% in 2018 to 52% in 2021.

There are four main proposals presented by Iluna Group during Milano Unica:

• Flock in flounce or allover entirely made with recycled ingredients and equipped with endless printing possibilities, with 3D and multicolor effects that allow the inclusion in fashion, underwear and athleisure looks. All certified GRS (Global Recycled Standard).
   
• Continued investment in both the Green Label and Bioline, two collections totally dedicated to innovative and responsible aesthetics. Both include lace made with the responsible 6.6 polyamide yarn Amni Soul Eco® and the degradable stretch fiber ROICA™ V550, combined with natural vegetable dyes with OEKO TEX and GOTS certifications.
   
• The union of a chenille yarn blended with FSC-certified viscose and Renycle® yarn, a product obtained by recycling nylon 6, a high-value material with excellent strength, dyeing, softness and versatility, gives life to surprising new Textronic. The embossed designs with 3D effect create a cloud effect that, combined with Lurex, gives unexpected glows.
   
• GRS-certified tulles printed with GREENDROP technology, the new GOTS-certified digital pigment printing system, with lower energy consumption and low water waste, thanks to an internal closed-circuit process for water recycling.

Baldwin Technology Company Inc. will showcase a new generation of innovative technologies for optimized corrugated high-graphics package printing at SuperCorrExpo, taking place in Orlando, Florida, from Aug. 8 to 12.

The FlexoCleanerBrush™ enhances the print quality and improves worker safety in corrugated printing. The system automatically removes dust and contamination from the plate in seconds during production, without stopping the press. It also performs full end-of-job plate cleaning and drying in fewer than four minutes, enabling increased uptime and sustainability. A carbon fiber core keeps even the ultra-wide FlexoCleanerBrush to a minimal weight, and ensures cleaning is stable, uniform and consistent throughout the plate’s width. Because the system is fully automatic and spans the entire width of the plate cylinder, the FlexoCleanerBrush improves safety by eliminating routine operator contact with the machine, while also reducing the risk of cylinder nip injuries and contact with wash agents.

Also on view in Baldwin’s SuperCorrExpo booth, the FlexoDry™ is a fully integrated IR drying system, specifically developed for corrugated flexo printing presses. It reduces energy consumption by up to 30 percent over standard IR dryers through patented Diamond IR™ lamps. The system delivers improved drying results because of a unique optical design that produces higher intensity for enhanced color definition, and reduces or eliminates marking altogether, allowing for high-speed and full-confidence printing.

Additionally, Baldwin will showcase LED-UV technology, designed by its AMS Spectral UV division for wide-format flexo corrugated box printing.

The Oerlikon Manmade Fibers segment will be presenting itself at the Egy Stitch & Tex 2020 between March 5 and 8, 2020 in Cairo – with a clear focus on the needs of the African market. In Hall 1, Stand B2 The Oerlikon Barmag and Oerlikon Neumag experts will also be showcasing the comprehensive product and service portfolio of the world market leader for manmade fiber systems at the stand of Oerlikon’s representative ATAG Export & Import.

The spotlight of the Oerlikon Manmade Fibers segment’s trade fair attendance will be on two core technologies: the new generation of Oerlikon Barmag eAFK Evo texturing machines is to be unveiled within the African market for the very first time. It promises higher speeds and productivity with consistently high product quality, along with lower energy consumption and simpler operation vis-à-vis comparable market solutions. In particular, the numerous value-added features include two that convince with cutting-edge technology: the optimized, innovative EvoHeater and the EvoCooler, a completely newly-developed active cooling unit.

The second technology focus offers new opportunities for the Egyptian market and the Middle Eastern markets in particular: with Oerlikon Neumag’s BCF S8 monocolor and tricolor system, the segment will be unveiling its new carpet yarn production flagship. Superlative spinning speeds, up to 700 individual filaments, finer titers of up to 2.5 dpf – the performance data and technological finesse of the new system have already made a huge impression at numerous trade fairs and roadshows over the past year. The tricolor’s core component is the new, patent-pending Color Pop Compacting unit (CPC-T) for even more flexible and more even color separation. With the CPC-T, individually-controllable air pressures for each color provide pre-tangling, which accentuates the colors and hence makes more than 200,000 different shades possible. Whereas it has been very difficult to manufacture strongly color-separated or color-accentuated BCF yarns from polyamide 6 to date, this will in future be possible thanks to the CPC-T system. As a result of the new design, the CPC-T is now also suitable for processes with low yarn tensions.
 
Expanded product offering for manufacturing carpet yarns
Know-how covering all relevant technologies deployed in manmade fiber spinning plants enables Oerlikon – as the world’s only manufacturer – to expand its range of products and services for making carpet yarns. The POY- and texturing-based system concept is designed for a carpet and home textiles segment that demands particularly soft and bulky polyester yarns with BCF-like properties. Here, the aim is to produce yarns with titers of max. 1300dtex and typically more than 1,000 filaments, with typical products including, for example, 1300dtex f1152, 660dtex f1152 and 990dtex f768. The machine concept comprises the well-known WINGS HD POY winder, along with the eAFK Big-V texturing machine.

BorPure™ RF777MO: designed for flip-top cap applications
Borealis announces the commercial launch of BorPure™ RF777MO. Based on the proprietary Borstar® Nucleation Technology (BNT), this new resin fulfils value chain demand for high-quality solutions offering excellent organoleptics. As next generation random polypropylene (PP), BorPure RF777MO has been designed for use in flip-top caps, a growing caps and closures market segment.

Next generation random PP offers excellent organoleptics
The rapidly evolving caps and closures industry must respond to a broad and diverse set of requirements from all sides. Converters demand innovative material solutions that reduce energy consumption and help increase productivity on injection moulding lines. Resins must offer easy processability, consistency, high quality, and provide optimal performance on the capping line. For brand owners and final consumers, caps and closures must secure package contents, provide ideal organoleptic properties, safety, and convenience. They must also stand out on the retail shelf and, increasingly, offer the lowest possible environmental footprint.

A. Monforts Textilmaschinen GmbH & Co. KG presented an energy-optimised new version of its industry-leading Montex stenter for the first time at ITMA 2019 in Barcelona from June 20-26th.

With the introduction of the new MonforClean exhaust air treatment system and other unique process innovations, Monforts has been able to further reduce the energy consumption of Montex stenters by a further 13%.

Exhaust air treatment on stenter frames has posed particular challenges over the years, since the air can contain significant amounts of oil, fibre and even wax particles that may see emissions limits being reached in the processing of certain fabrics, depending on the legal specifications.

In addressing this issue, Monforts is now incorporating the MonforClean module into the stenter frame, so there is no additional space requirement. At the same time, the costs for laborious secondary installations and the piping of the exhaust air treatment components, as well as supporting structures are eliminated due to the machine configuration.
