Ein Garn zu spinnen, ein Gewebe oder Gestrick zu produzieren, anschließend zu veredeln und zu einem fertigen Textil mit breiten Anwendungsfeldern zu konfektionieren, benötigt viel Know-how. Passend dazu bieten Textil- und Bekleidungsunternehmen Ausbildungsberufe an, deren Anwendungsfelder ganz nach dem Motto „Textil kann viel“ nicht vielfältiger sein könnten. Produktionsmechaniker*innen Textil können ihr Geschick im Umgang mit Maschinen unter Beweis stellen; Produktveredler*innen Textil sind direkt in das Veredeln und Färben eingebunden; Textil- und Modeschneider*innen verwandeln Stoffe in Kleidungsstücke und andere Produkte. Auch Ausbildungen im kaufmännischen Bereich, in Logistik oder IT hat die Industrie zu bieten.

„Wir möchten noch mehr junge Menschen für eine Ausbildung in unserer spannenden und innovativen Branche begeistern. Deshalb investiert Südwesttextil mit dem Bau des Texoversums auf dem Campus der Hochschule Reutlingen in die Zukunft der Ausbildung. Das Texoversum ist einer der Orte, an dem die textile Aus- und Weiterbildung ihre Innovation und Attraktivität aufzeigt und vorantreibt“, so Edina Brenner, Hauptgeschäftsführerin des Wirtschafts- und Arbeitgeberver-bands Südwesttextil.

In den Nachwuchs zu investieren hat beim Verband der Südwestdeutschen Textil- und Bekleidungsindustrie e.V. Südwesttextil Tradition: Seit 1980 sind in der Gatex, der überbetrieblichen Aus- und Weiterbildungsstätte der Branche, mehr als 1.000 Menschen erfolgreich qualifiziert worden. Auszubildenden ermöglicht die Gatex das Lernen entlang der textilen Kette, sodass sie im Anschluss im Betrieb auch vor- oder nachgelagerte Stufen der Produktion mitdenken können.
 
Mit dem Umzug der Gatex von Bad Säckingen nach Reutlingen setzt Südwesttextil auf einen zentralen Ort und die Verknüpfung mit dem Studienangebot der Hochschule. Schon jetzt schnuppern die Auszubildenden Campusluft, denn das überbetriebliche Ausbildungsjahr beginnt direkt in Reutlingen. Das Texoversum wird im Frühsommer des nächsten Jahres eröffnet und bietet dem textilen Nachwuchs Raum fürs Lernen, Ausprobieren und Vernetzen. Denn in den 3.000 Quadratmetern des innovativ gebauten Gebäudes befinden sich neben Schulungsräumen auch Werkstätten, Labore und Think-Tank-Flächen.

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.

SHIMA SEIKI MFG., LTD. of Wakayama, Japan, along with its Italian subsidiary SHIMA SEIKI ITALIA S.p.A., will be participating in the Techtextil exhibition in Frankfurt, Germany from the 21st till the 24th of June 2022.

On display will be SHIMA SEIKI’s latest innovation in flat knitting technology as applied to the field of technical textiles—a prototype weft knitting machine capable of multi-axial yarn insertion. Fabrics produced on this machine use inlay technique for the production of hybrid textiles that combine the stretch characteristics of knitted fabrics with the stability of woven textiles, suited to various technical applications. To this, warp yarn is inserted to further expand its capability to produce 3D-shaped carbon fiber and composite preforms directly on the machine. This is made possible by taking advantage of the fact that flat knitting as a textile production method is capable of producing end products that are shaped-to-form and with added thickness. Compared to current methods of preform production, savings in post-processing time, material, labor and associated costs are immense, realizing efficient and sustainable production. SHIMA SEIKI’s own yarn unwinding technology is also used for optimum yarn feed and tension for use with technical yarns that are otherwise difficult to knit. Industrial textile samples knit on the multi-axial machine will also be available for examination on-site.

SHIMA SEIKI's SDS®-ONE APEX4 3D design system will be available for demonstrations as well. Of particular interest should be its ultra-realistic simulation capability that realizes Virtual Sampling. When countless 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, cost and material normally associated with producing actual samples for each variation. When approved, the same data can be converted to machine data for immediate knitting, significantly reducing lead times.

The German machinery producer BRÜCKNER used exactly these chances and repositioned itself during the pandemic period. For more than 70 years, the family-run company has been specialized in individual finishing concepts for textiles, technical textiles, nonwovens and floor coverings. The current challenges in the textile industry are serious. The clear increase of the energy costs and the general uncertainty of the energy supply as well as political requirements make a profitable textile production more and more demanding for many companies.

The company responds to this with a newly developed stenter concept with double heating system. Depending on availability, the lines can be operated with gas or oil, but also other combinations with steam or renewable energies are possible. This means that production delays and machine downtimes can be avoided as far as possible. In addition, developed intelligent assistance systems for its machines have been developed that support the machine operator in using the best possible process to operate the line as energy-efficiently as possible. Further energy savings are possible with new energy-efficient motors or heat-recovery and exhaust air cleaning systems. This also helps to avoid harmful emissions.

But many textile producers are also focusing on reducing chemicals. For this purpose, BRÜCKNER's further developed ECO-COAT minimum application unit can make a decisive contribution. Knitted and woven fabrics, but also nonwovens can be finished on one or both sides via different fabric paths. With the minimum application via an engraved roller, a single-sided application of up to 100 g/m² can be achieved. A double-sided and higher application quantity is achieved, for example, by impregnation in the nip. Irrespective of the selected fabric path, a very small liquor reservoir means that only minimal quantities of waste water are produced when changing batches or liquors, and the use of chemicals can also be significantly reduced. In addition, less water has to be evaporated in the subsequent drying process than, for example, in the case of impregnation in a water bath, so the energy requirement is significantly reduced.

On the two upcoming trade fairs ITM in Istanbul and TECHTEXTIL in Frankfurt in June, interested customers can personally get an idea of BRÜCKNER's new developments.

International technology group ANDRITZ will be presenting its innovative nonwovens production and textile solutions at Techtextil in Frankfurt from June 21 to 24. The ANDRITZ product portfolio covers state-of-the-art nonwovens and textile production technologies, such as air-through bonding, airlay, needlepunch, spunlace, spunbond, wetlaid/WetlaceTM, converting, textile finishing, recycling, and natural fiber processing. For Techtextil, special focus lies on technologies for textile recycling, needlepunch, airlay, wetlaid glass fibers and textile calendering.

TEXTILE RECYCLING TECHNOLOGIES BASED ON TEARING
With the acquisition of ANDRITZ Laroche SAS, ANDRITZ has expanded its product portfolio to include airlay and recycling technology as well as bast fiber processing technologies. Complete recycling lines for post-consumer and industrial textile waste to produce fibers for re-spinning and/or nonwoven end-uses are one focus of this product range. Customer awareness and regulations are forcing clothing brands to recycle their textile waste in their own products. Recycled fibers can also be used in the nonwovens industry for various applications, for example in the automotive industry, for insulation, mattresses, and furniture felts.

ANDRITZ Laroche offers a complete process range of tearing lines from 50 up to 3,000 kg/h, which can be used for almost all types of pre/post-consumer textile waste. The aim is to preserve the character of the original fibers, for example cotton, by maximizing fiber length, strength and feel.

The DiloGroup informs at Techtextil in Frankfurt (June 21 – 24, 2022) about new developments aimed at improving production technologies with a focus on needlefelts.

It becomes more evident that the textile industry comes into the focus of regulatory authorities who push respecting sustainability principles and who initiate a new body of laws. Hence all industrial sectors are requested to achieve savings in material and energy. The textile machine building, of course, plays an important role by seizing this initiative and offering solutions for fibre pulp recycling and reduction of energy, water and ancillaries. DiloGroup has made big efforts to meet these challenges together with a circle of partner companies. In this regard focal points of the development work are:

1. Intense Needling
   Needling per se is a mechanical production method with a high energy efficiency. For this reason, the development efforts of DiloGroup aim at producing nonwovens by “intense needling” instead of water entangling, even for light nonwovens made of fine fibres for the medical and hygiene sector with an area weight of 30 – 100 g/m². This would result in a reduction of the environmentally relevant production costs; per annum to about 1/3 to 1/5 of current.
   Despite the prospective advantages of the mechanical intense needling method over the hydrodynamical, water entanglement is at the moment the most important production method for low area weights and highest production capacity and is also offered by the DiloGroup as general contractor in cooperation with partner companies.
2. “Fibre Pulp Recycling”
   Fibrous material in nonwovens and particularly used clothes can be successfully recycled, if staple length can be conserved in the tearing process. In the classical tearing process, staple lengths are dramatically reduced and therefore these fibres can only be used as base material for inferior uses in thermal or acoustic insulation or in protective textiles, transportation or protective covers etc.
   When recycling textile waste in the context of the collection of used clothes, the so called “filament-saving” tearing using special tearing machines and methods must be used to produce fibres with longer staple lengths which can be fed to a nonwoven installation. Hence product characteristics can be better specified and controlled.
3. Additive nonwoven production
   The additive production method of the “3D-Lofter” is especially suited for automotive parts with differently distributed masses; but there may also be potential for increasing uses in the sector of apparel and shoe production.
4. “IsoFeed”-card feeding
   In the field of card feeding, the “IsoFeed” method offers great potential for a more homogeneous card feeding at the same time reducing the variation in cross-machine fibre mass distribution and thus the fibre consumption while conserving the end product quality.

High-performance yarns now offer almost unlimited possibilities for replacing traditional raw materials in a vast range of technical applications. Often tailor-made, these filament yarns go way beyond the conventional idea of ‘textiles’ – finding new uses in sectors such as automotive, aviation, maritime, medical and construction, among many others.

Technical textiles are everywhere in our daily lives today, even if we may not always realize it. Some are in more obviously textile products, from sewing threads to artificial turf. But then, take cars as an example: modern vehicles are stuffed with parts made from sophisticated yarns. It’s common for producers of automotive parts now to send template material and requirement lists to Swiss Textile Machinery members, trusting their expertise and experience. Members operate development and testing centers with latest machine installations, where their experts devise customized solutions, as well as calling on the pure innovative spirit which is part of their DNA.

At the extremes
Technology drives applications beyond our current imagining in the case of Heberlein air splicers. Developed for a wide range of uses with high-strength technical fibers, they have no problems splicing aramid fibers up to 16’100 dtex, carbon up to 30’000 dtex, Dyneema up to 5’500 dtex, and glass up to 4’800 tex. Using compressed air, the splicers produce a tear-resistant, homogeneous splice of material without interfering knots.

Retech has the technology to achieve specifications for filament yarns, drawing and stretching fibers to perfection. Top heated godet rolls – many customized – are developed for high-performance fibers. Temperatures up to 400 °C can be achieved. Combining the right settings and wide speed ranges for each specific process results in unique end-products.

Fabric producers of high-end applications must avoid any quality risk. Yarn producers are well aware of this responsibility, so they use precision package winders for technical yarns, developed by Rieter’s subsidiary SSM. Taking yarns from ring twisting bobbins, its specialist finish winders can produce coarse-count technical yarns up to 50’000 dtex, offering a new level of flexibility and winding quality.

Lifestyle essentials
At first glance, motorists might fail to notice many of the technical yarns ‘hidden’ inside their cars. These products have functions such as providing stability with hardly any weight, or absorbing tensile forces at defined elongation. This kind of controlled elongation behaviour, for example, arises from the choice of textile material and the special construction of the yarns used.

Such specifications make twisting and cabling machines essential for the automotive industry. Saurer offers machines for the production of technical yarns made from a variety of feed materials in a very wide yarn count range. They are needed for vehicle products such as tire carcasses, toothed engine belts, seat belts, airbags and lorry tarpaulins.

Technical yarns also play a surprising role in our mobile devices. Tapping, scrolling and swiping are second nature for billions, with our phones and a plethora of other lifestyle essentials. Yet, how many people would know that the touch-sensitivity we take for granted on these screens is largely made possible by twisted glass fibers. Bräcker, part of Rieter’s components business, offers a selection of vertical sinter metal rings and nylon travelers for glass fiber twisting, so that mills can achieve high levels of productivity and quality.

Future unlimited
Automotive and communication technology are already important industries for Swiss Textile Machinery members, along with well-known technical textiles markets in sectors such as medical, transport and construction. Smart-wear is already noted as a field with significant potential. Naturally, members are constantly investigating other possibilities. Swiss textile machinery is already applied in energy (batteries), and plastics.

The Swiss Textile Machinery Pavilion will be at the Techtextil exhibition in Frankfurt, Germany, taking place from 21 to 24 June 2022.
