HeiQ will showcase some of its latest technologies at the Taipei Innovative Textile Application Show – TITAS 2022, from the 12th to the 14th of October, at the Taipei Nangang Exhibition Center. A newly launched, upgraded formula - HeiQ Barrier Eco Dry New, is added to the company’s fluorocarbon-free water repellent technology range and will be one of the highlights.

As urbanization and modern lifestyles cause an estimated 40% of the global population to be afflicted by allergies, HeiQ recently launched HeiQ Allergen Tech, a finish based on bio-based synbiotic technology to combat inanimate allergens on textiles. It will also be introduced at TITAS.

HeiQ innovations driving change
The global call for sustainability has put the textile industry, as the second-highest generator of CO₂ emissions, under the spotlight. Most of the marine pollution is caused by non-degradable micro-and nanoparticle emissions from washing clothes, and tons of textile items pile up in landfills. Clothing a potential 8Bn global population by 2023 doesn’t have to be a problem, and HeiQ is driving change in the textile industry so that every player can be part of the solution. In response to the ongoing energy crisis, HeiQ will emphasize the use of HeiQ Clean Tech, a polyester dyeing auxiliary system that helps mills save energy by 30-35%, thereby reducing the carbon footprint of the finished product.

As a sub-exhibitor of Oerlikon, BB Engineering will present its product range in the fields of extrusion, mixing and filtration as well as PET recycling with the VacuFil and VarioFil R+ systems at the K show 2022.

BB Engineering has been focusing its development work increasingly on recycling technologies for several years. In addition to extruders, filters and mixers that are suitable for both recycling processes and the processing of recyclate, BB Engineering offers a complete PET recycling plant called VacuFil.

With VacuFil, BB Engineering has developed an innovative PET LSP recycling process. The process combines gentle large-scale filtration and targeted IV regulation for consistently outstanding rPET melt quality. Thus, much more than simple "downcycling" is possible with VacuFil. VacuFil processes a wide range of input materials - post-production and post-consumer. The patented key component Visco+ vacuum filter removes volatile impurities quickly and reliably. VacuFil is a modular system that can be designed for different recycling applications. Simple granulation is possible, but also direct feeding into further processing, e.g. in the synthetic fiber spinning mill. BBE offers VacuFil in combination with its own VarioFil compact spinning plant to produce polyester yarn.

At the K show 2022, visitors can experience the VacuFil Visco+ recycling technology in operation with a connected VarioFil spinning plant and see live how recycling yarn is produced from PET waste.

Brazil hosts all industries needed for textile and garment production - from fiber to final production. This is why Mahlo, with its diverse solutions on straightening technology and process control, will exhibit at Febratex, held on August 23-26 in Blumenau.

"No matter what products they make, all producers have the same goals at the end of the day," says Area Sales Manager Miguel Lessel. "High-quality goods without distortion and optimized processes that combine quality and economy.

The automatic straightening system of the world market leader ensures thread-straight fabric in almost all applications. The modular system can be adapted to individual production conditions. To optimize the processes around the stenter frame, Mahlo offers various process control systems. These can be used, for example, to measure and control critical parameters such as dwell time, thread density or residual moisture. These systems not only help to improve the quality of the textiles, but also to save raw materials and reduce energy costs.

• Focus on straightening technology and process control

At Indo Intertex, held from 10 to 13 August in Jakarta, visitors get to see the Mahlo-way for process control in textile production. The German machine manufacturer and its partner agency Agansa Primatama will be available to show everyone its leading straightening technology as well as energy saving concepts around the stenter frames. INDO INTERTEX is South East Asia’s largest trade show on the textile and garment industries, bringing together leaders to experience world-class manufacture, technology and solutions.

Indonesia is one of the ten biggest textile producers in the world. Especially the USA, the European Union and Japan import a majority of their requirements from the Southeast Asian Island state. In order to fulfill the increasing demands and the call for high quality goods, producers invest in machinery, equipment and technology.

At IndoIntertex, Mahlo informs about its straightening machine Orthopac RVMC-15, among other. Based on experience reaching back to over 75 years, the machine offers the latest technology for correcting distortions. The modular straightening and process control system ensures a straight-thread product before and after the drying or fixing process and optimises the processes all around the stenter. This increases quality and saves resources and energy. The process control system Optipac VMC-15 measures and controls critical parameters such as dwell time, thread density or residual moisture.

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.

The recent Techtextil show in Frankfurt emphasised the diversity of applications for nonwovens and technical textiles, according to finishing technology specialist Monforts.

“We fielded enquiries at top management level from an extremely wide range of companies, all with very different ideas for new product applications during the show,” said Alexander Fitz, who joined the company a year ago as engineer for textile technologies and co-ordinator of the Monforts Advanced Technology Centre (ATC). Fitz brings a background in both technical textile technology and processes to the role, having previously worked for a nonwovens machinery builder and a roll-goods manufacturer.

Trials
“We are now looking forward to interesting new trials and pilot production runs, as well as the commissioning of new orders for machines resulting from the extremely busy exhibition,” he says. “Obviously, everyone at the moment is looking to make energy savings, and we have developed a range of options for helping companies increase their resource efficiency, both on new lines and as retrofitted systems, but this is not stifling innovation at the new material level.

“There was a lot of interest in what is possible with the Montex®Coat coating system and the range of different techniques it enables, and at our ATC in Mönchengladbach, a Montex®Coat unit is integrated into the full technical textiles pilot line, on which it is possible to run new fabrics in widths of up to 1.8 metres.”

Explosion proof
The technical textiles line at the ATC incorporates a Montex four-chamber stenter and is fitted with an explosion-proof coating application chamber in order to allow treatment to be carried out with organic solvents and other volatile materials.

Every single component within the chamber has to meet the standards of the European Union’s ATEX directives for working in a potentially explosive atmosphere. A range of sensors linked to alarms operate at various levels within the chamber to ensure the specified lower explosion limit (LOL) is never exceeded and the ventilation adapts accordingly.

Advanced functions
Special features on the finishing line relate to further advanced functions such as the ability to treat materials not only at temperatures of up to 320°C, but also to be able to treat the top and bottom faces 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 special, heavy duty TwinAir ventilation motors and separate burners for individual top/bottom temperature. A temperature differential of up to 60°C can be achieved between the upper and lower nozzles within the chamber, depending on the treatment paramenters.

Another key feature of the technical textiles line at the ATC is the 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.
