From the Sector

Stahl, a provider of speciality coatings and treatments for flexible substrates, has launched the protective coating Stahl Integra® Dry 725, meeting the increasing demand for water-repellant technical fabrics.  
 
Part of the Stahl Integra® toolbox, Stahl Integra® Dry 725 is a fluorine-free coating for water-repellent technical textiles that harnesses Stahl’s proven polymer technology. Stahl has introduced Stahl Integra® Dry 725 in response to the growing market demand for fluorine-free, water-repellent technical textiles, which is projected to reach USD 605.1 million by 2029.  

Stahl Integra® Dry 725 offers a balanced performance between repellency, durability and adhesion. Stahl's durable water-repellent (DWR) technology, StayDry, repels water from fabric by modifying the surface tension of fibres. The solution can be combined with other top or back coatings and is specifically designed for technical textile applications such as camping equipment or luggage. As a fluorine-free, waterborne coating that is cured at low temperatures, Stahl Integra® Dry 725 can help reduce environmental impact without compromising on quality.

Stahl Integra® is a modular 'toolbox' of tailor-made, customer-orientated protective coating solutions that simultaneously ensure product quality and superior fabric integrity. This means that specific mechanical functionalities – from flame-retardant and breathable coatings to stay-clean technologies – can be introduced at different stages of the production process to meet specific end-market requirements as needed.

Cavitec, part of Santex Rimar Group, presents the redesigned Caviscreen at Techtextil Frankfurt. Caviscreen features latest technology for breathable laminates.

Caviscreen was developed as a hotmelt coating and laminating unit for breathable sportswear, rainwear and protective clothing – with and without applying a membrane. The redesigned machine shows a brand-new method to supply adhesive more evenly and precisely. Using PUR adhesive (polyurethane reactive adhesive) goes with additional benefits like strong bonding capabilities and versatility.

Caviscreen’s hotmelt screen printing is a special system for high-end application garments. With this Caviscreen system, a PUR adhesive is transferred onto the substrate through a rotary screen, similar to the well-established textile printing method. The adhesives are fed from the drum melter through a heated hose to the traversing adhesive distribution system inside the rotary screen, just behind the doctor blade.

The adhesive is pressed by the doctor blade through the screen holes and transferred to the substrate. Different dot pattern (mesh or irregularly) and different screen thicknesses allow different coating weight and adhesive coverages.

The traversing adhesive dispenser is used to distribute the adhesive automatically over the set working width that – an additional technical benefit – can be set without any mechanical changes.

Cavitec’s screen coating system achieves high bonding strength while using less adhesive than other coating processes, because of applying the coating on the surface of the substrate and like this, the adhesive has less tendency to penetrate the substrate.

Bonding strength, softness of the fabric and the breathability are defined by the coating weight and the coverage. The rotary screen allows users to regulate and adapt the coverage respectively the coating weight. Cavitec offers a large selection of screens that are essential to fulfil the fabric requirements. A further advantage is the ease and efficiency of switching from one screen to another by simply unlocking the bayonet fitting. The IR-heater cover opens pneumatically and the lightweight screen can be easily removed by hand. Unlike with other methods, there's no need to deal with hot oil or any other heated liquid that requires cooling down.

The Caviscreen technology supports manufacturers by reducing costs with screens priced at a mere fraction, just 10%, of common gravure roller prices.

Purecare, a wellness-focused bedding essentials manufacturer, has launched sheets and pillowcases with CELLIANT® Viscose, the first time the fiber has used been in luxury bedding products in a new offering aptly named the “Recovery Collection.”

Developed by materials science innovator Hologenix®, creators of CELLIANT, and Kelheim Fibres, CELLIANT Viscose is the first in-fiber sustainable infrared viscose. It is lightweighted, soft, highly breathable and has an excellent moisture management. CELLIANT has been clinically demonstrated to promote faster recovery and restful sleep, as it improves local circulation and cell oxygenation, enhancing thermoregulation and comfort.

The collection is available in five colors: dove gray, ivory, clay, moss, and sage in Queen through Split California King sizing and Queen and King pillowcases. The Precision-Fit® corners on the fitted sheets have a one-inch elastic cuff to ensure that they stay securely on the bed. The sheets are also compatible with adjustable base mattresses. The Recovery Collection sheets and pillowcases are also treated with Antimicrobial Silver Product Protection (AgCI).

Mey GmbH & Co. KG, a global manufacturer of underwear, nightwear and lingerie based in Germany, is launching the world’s first men’s nightwear with CELLIANT® Viscose, which converts body heat into infrared energy.

Called mey Zzzleepwear - THE NEW SLEEP-LIFE BALANCE, the collection follows the successful debut of the similarly named women’s collection in 2021. It consists of four designs in Indigo available in T-shirts, short pants, long-sleeved shirts and long pants. CELLIANT works by recycling the heat emitted by the body into full-spectrum infrared energy and then returns it to the body. As a result, it increases the supply of oxygen to the cells and promotes a restful sleep.

CELLIANT Viscose was developed by Hologenix®, creators of CELLIANT, a textile-based infrared ingredient brand, and Kelheim Fibres, a leading manufacturer of viscose specialty fibers. CELLIANT Viscose features natural minerals embedded into plant-based fibers and is biodegradable. It provides all the benefits of being a viscose fiber — lightweight, soft, highly breathable, excellent moisture management — as well as the fiber enhancements from CELLIANT infrared technology. In addition, CELLIANT is durable and will not wash out.

• Partnership with Spectro Coating Corp. Expands Horizons for the World’s First In-fiber Sustainable Infrared Viscose

CELLIANT® Viscose, which converts body heat into energy, is a combination of nature and performance. It was developed by materials science leader Hologenix®, creators of CELLIANT, a natural blend of IR-generating bioceramics used in textiles, and Kelheim Fibres, a leading manufacturer of viscose specialty fibers. It is the world’s first in-fiber sustainable infrared viscose.  Now Hologenix has partnered with Spectro Coating Corp., the largest vertically integrated flock coating and flock fabric manufacturer in the world, to create the first flocked infrared material with CELLIANT Viscose.

Flocking is an application method in which tiny fibers are piled on to the surface of a textile, creating textures for both decorative and functional purposes. CELLIANT Viscose in a flocked material has many potential applications in the medical field for tapes, bandages, braces and orthopedic products, home textiles and decor, dog beds, clothing, and more.  CELLIANT features natural, ethically sourced minerals, which convert body heat into infrared energy for increased local circulation and cellular oxygenation.  These CELLIANT minerals are then embedded into viscose plant-based fibers. The Viscose fibers are then flocked onto a base material. CELLIANT Viscose provides all the benefits of being a viscose fiber — lightweight, soft, highly breathable, excellent moisture management — as well as the fiber enhancements from CELLIANT infrared technology.

CELLIANT Viscose is the first IR flocked material that Spectro is producing. CELLIANT Viscose also represents a further expansion into sustainable products for Spectro. In addition, Spectro products are made in the USA, as is CELLIANT’s mineral blend.

• Experienced nonwovens professional with extensive hygiene, food, medical, and packaging background will strengthen INDA’s key member service areas

INDA, the Association of the Nonwoven Fabrics Industry, announced the appointment of Matt O’Sickey, Ph.D., as its new Director of Education & Technical Affairs. An accomplished market development, technology and product management executive, O’Sickey has more than 20 years of experience with Tredegar Film Products in the absorbent hygiene, food, and medical sectors.

Most recently, he held Director positions at RKW-North America in the areas of research and development, product design, application engineering, site operations, quality, and technology with a focus on breathable, and lamination films for controlled atmosphere packaging.

At INDA, O’Sickey will direct and expand workforce development programs for all industry members, manage the international harmonized standards activities, and play a leadership role in INDA’s product stewardship working groups and conference content development committees.  

O’Sickey has a Ph.D. in Chemical Engineering and a Master’s degree in Engineering Administration, both from Virginia Tech as well as a Bachelor of Science in Chemical Engineering from Purdue University. He holds three U.S. patents. He will operate out of INDA’s offices in Cary, NC.

O’Sickey succeeds Chris Plotz who left INDA to pursue other interests. 

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.

ROICA™ strengthens its presence in the apparel segment thanks to its established network of partners, who will present their latest innovations at the upcoming Première Vision.

ROICA™ partners are the “artists” and “heartists” of premium stretch in fabrics: because they have at heart all the values for which ROICA™ stands for. These partners presenting at Première Vision are:

• Iluna Group, whose journey into the new dimension of responsibility continues with developments in GRS (Global Recycled Standard) certified recycled yarns aimed at unprecedented effects in looks, performance and hands. Brand new for this edition of Première Vision is the inclusion of GOTS-certified organic cotton in GRS-certified galloons and allover lace containing ROICA™ EF, so as to meet market demands for natural comfort in the underwear sphere.
• Innova Fabrics, which recently enhanced its smart offering by launching the RF (Residual Free) line, with the goal of reducing the impact of microplastics derived from the fashion industry. This is made possible by mixing two responsible ingredients, SENSIL® BioCare by Nilit and ROICA™ V550 by Asahi Kasei, which give birth to both sporty and casual fabrics.
• Inplet, which enriched its production of smart elastic and rigid knitted fabrics with three new products: a powernet fabric in 77% polyamide RECO and 23% ROICA™ EF with good recovery; a net fabric in 55% polyamide RECO and 45% ROICA™ EF characterized by a soft hand and good elasticity; and a 79% polyamide and 21% ROICA™ V550 good power, good recovery and a soft touch.
• Penn Textile Solutions/Penn Italia, whose highlights of the new collection are on one side fabrics developed with the use of Neride eco yarns by Nurel with ROICA™ V550, characterized by restraining lace effect, soft touch and breathable, in combination with tulle as a sustainable basic, and on the other side charmeuses with soft hand, raw cut in combination with a band fabric from the dreamshape family with reinforced gripping edge, made again in Neride eco yarns by Nurel with ROICA™ V550
• Tessitura Colombo Antonio, which in its new A/W 23-24 collection expands its proposal of regenerated lace from the ECO-LACE line: new designs inspired by fashion trends using ROICA™ EF. Also, in its BIODEGRADABLE line it uses ROICA™ V550 for the realization of new designs. The new MICROMODAL line uses ROICA™ V550; the effect of this lace range is softness, elegance and relief effect.

The Saxon Textile Research Institute (STFI) will be presenting innovative highlights from research and development at Techtextil 2022, the international trade fair for technical textiles and nonwovens. In addition to a warp-knitted textile façade greening in a modular system and textile lightweight construction elements for the building sector made from hemp as a renewable raw material, the STFI will also be showing innovations from nonwovens research. The project optiformTEX is an example of the nonwovens competence: in this project, the mass per unit area was specifically influenced for the production of semi-finished products in the automotive sector. Furthermore, the Chemnitz Institute exhibits an ecological foam coating for protective textiles. Central highlight of the STFI's presence at the fair is also a mobile robot system, which demonstrates the automated loading of a small-scale bobbin creel.

Highlights at Techtextil 2022
The greened façade tile is a system with which large building surfaces can be cost-effectively greened through a simple, modular segment structure. In addition to insulating the building, the system has been created to meet the design requirements of a modern city centre; low-maintenance greening is made possible through functional integration in the textile carrier layer and coordinated plant selection.

Moulded components made of natural fibre nonwovens are increasingly used in the automotive sector. Conventional nonwovens currently have uniform masses per unit area. Technical solutions for load-oriented component reinforcement and the resulting optimised use of materials represent an enormous economic potential. The basic idea of “optiformTEX” was therefore to specifically influence the mass per unit area distribution in the pile before the semi-finished product is consolidated. As a result, a textile-technological process and the corresponding plant component were successfully developed.

Future-oriented materials are offered by developments from the field of renewable raw materials in combination with bio-based resin systems: In the “Gro-Coce” project, an innovative ceiling system was developed by combining sustainable building products and methods. Currently, a high-performance hemp-based semi-finished product as well as the steps for its reproducible production by means of textile surface formation is developed by the research team. Initial application and load tests of the hemp-based semi-finished products on wooden beams confirmed the high performance potential of the natural fibre materials.

Special functional textiles are based on composite materials with coatings or membranes. The previous production of the coatings/membranes poses ecological and health risks. At STFI, solvent-free, purely aqueous coating systems and a technology for their application were therefore developed for the protective textile sector, resulting in a breathable, waterproof and wash-resistant textile coating.

The central highlight of the STFI's presence at the fair is a mobile robot system, which demonstrates the automated loading of a small-scale bobbin creel. At the STFI, the robot is part of the “textile factory of the future”, where a play mat is woven and processed step by step along the textile chain.
