From the Sector

SHIMA SEIKI ITALIA S.p.A., Italian subsidiary of leading Japanese computerized knitting solutions provider SHIMA SEIKI MFG., LTD., will exhibit at the 92nd edition of the Pitti Immagine Filati exhibition in Florence, Italy. Products exhibited will include the new SWG-XR®154 and N.SVR®183 computerized flat knitting machines as well as APEXFiz® design software.

As pioneer of seam-free WHOLEGARMENT® knitting, SHIMA SEIKI has been setting the standard almost exclusively with nearly 30 years of experience in complete garment technology. Now that benchmark has been raised once again with its new SWG-XR® flagship WHOLEGARMENT® knitting machine. SWG-XR® features 4 needle beds for all-needle knitting of high quality WHOLEGARMENT® products using the company's original SlideNeedle®. SWG-XR® features a renewed sinker system and a compact, light-weight carriage featuring 4 systems as well as auto yarn carriers. All contribute to increased productivity of more than 25% over the previous MACH2®XS machine, as well as increased product range using a wider variety of yarn for supporting knits for all seasons, and higher quality for knitting beautiful fabrics and silhouettes; even items that were impossible to knit with the MACH2® series. SWG-XR® sets new standards for the next generation of waste-free, sustainable WHOLEGARMENT® knitting.

A new proposal in WHOLEGARMENT® knitting will also be introduced in the form of the N.SVR®183 WHOLEGARMENT® knitting machine. SHIMA SEIKI's global standard in shaped knitting, the N.SVR® series now features a model for producing WHOLEGARMENT® knitwear using every other needle in ultrafine gauge. N.SVR®183 is equipped with the R2CARRIAGE® system and a compact, lightweight carriage for even higher productivity. Shown in 21G at Pitti Filati 92, N.SVR®183 is the ideal machine for flexible, entry-level WHOLEGARMENT® production, with the versatility to respond to fluctuating market demand.

APEXFiz® subscription-based design software supports the creative side of fashion from planning and design to colorway evaluation, realistic fabric simulation and 3D virtual sampling. Virtual samples are a digitized version of sample making that are accurate enough to be used effectively as prototypes, replacing physical sampling and consequently reducing time, cost and material that otherwise go to waste. APEXFiz® thereby helps to realize sustainability and digitally transform the fashion supply chain.

The identification of profitable new niche markets has been central to the success and continuous expansion of Germany’s Dolinschek, a leading knitting, dyeing and finishing specialist, located in Burladingen in Baden-Württemberg.

“There is so much more to textiles than just clothing,” says Theo Dolinschek, who runs the company with his brother Erwin. “We handle many different technical materials such as automotive components, geotextiles and wallcoverings, but also those for more unusual applications such as inlays for extractor hoods, cut protection fabrics and even wool felts which are employed as insulation on wind turbines.

“We have also recently started to produce compression stockings in a variety of colours, because not everyone wants them black, beige or skin coloured. The most important product areas for us now are in sportswear, corsetry and lingerie, as well as orthopedic and medical products, workwear and protective clothing, but in addition, many other technical applications.”

The Dolinschek brothers moved their business to the historic site of the former Ambrosius Heim textile company in Burladingen in 2001 in order to expand. At the time, the company – founded by their father in 1980 as a textile wholesaler before moving into dyeing – employed just 13 people. Within a year, the company had bought additional space at the site.

Now, with Theo in charge of technology and sales, and Erwin responsible for production, the company employs almost 100 people and operates on an integrated site of 35,000 square metres.

In 2005, a laminating department was established by the company and since 2012 investment in knitting machines has been ongoing.

“The further we went into vertical integration, the more of our own products we were able to position on the market and so we were also able to make ourselves more independent,” says Theo. “We have continued to develop and today we can produce high-quality fabrics for many fields, with 42 knitting machines, 36 dyeing machines, three stenter frames and many other production and processing machines.”

Dolinschek has also developed its own proprietary TMG dyeing machines which have subsequently been successfully sold to many other companies all over the world. There are currently 11 of these machines  in operation at the Burladingen site and around 45 installed at other companies.

For finishing technology, however, the company relies on Monforts, and has installed a new seven chamber Montex TwinAir stenter range with a Montex®Coat coating unit in knife execution, enabling the coating of dimensionally stable knitted fabrics with polyurethane or acrylate. Another unique feature is the Teflon-coated (non-stick) transportation belt through the system.

The Montex line is also equipped with integrated heat recovery and exhaust gas purification to ensure the most resource-efficient processing available on the market. The exhaust air goes from the Monforts heat recovery system into an existing air/water heat recovery system and then into an electrostatic precipitator.

Highly-intuitive Monforts Qualitex visualisation software allows all machine functions and process parameters to be assessed and controlled easily.

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. will participate in the ITM 2022 International Textile Machinery Exhibition in Istanbul, Turkey.

SHIMA SEIKI will exhibit a wide range of its products, including proposals in seam-free WHOLEGARMENT® knitting technology that offers an alternative to labor-intensive manufacturing in Turkey and other international markets. Featured is the flagship MACH2XS WHOLEGARMENT® knitting machine with original SlideNeedle™ on four needle beds and spring-loaded moveable sinkers with expanded patterning capability, the MACH2VS V-bed machine for producing WHOLEGARMENT® items using every other needle, as well as the compact SWG091N2 for producing smaller WHOLEGARMENT® items and accessories. A brand new proposal in V-bed WHOLEGARMENT® knitting will also be introduced in the form of the N.SVR183 machine. N.SVR123SP features a special loop presser bed that can produce hybrid inlay fabrics with both knit and weave characteristics. N.SVR123SP at ITM will feature the special i-Plating option, capable of alternating yarn colors in any pattern, producing jacquard-like designs using plain jersey stitch for even greater diversity in knit design. Meanwhile N.SSR112 offers industry-leading technology in an economical yet reliable package made in Japan. Also on display is the SFG20 glove knitting machine.

Demonstrations will be performed on SHIMA SEIKI’s SDS®-ONE APEX4 design system. At the core of the company’s “Total Fashion System” concept, SDS®-ONE APEX4 provides comprehensive support throughout the production supply chain, integrating production into one smooth and efficient workflow from yarn development, product planning and design, to production and even sales promotion. Especially effective is the way SDS®-ONE APEX4 improves on the design evaluation process with its ultra-realistic simulation capability, whereby virtual samples replace physical sampling, consequently reducing time, cost and material that otherwise go to waste. The same capability is present in APEXFiz™ subscription-based design software. Installed on personal computers, APEXFiz™ features the same functionality as SDS®-ONE APEX4, but with the added versatility to adapt to different work styles and business environments including teleworking and telecommuting. Digital prototyping using virtual samples on SDS®-ONE APEX4 and APEXFiz™ help to digitally transform the fashion supply chain for realizing sustainable manufacturing. APEXFiz™ will be shown along with SHIMA SEIKI’s yarnbank™ digital yarn web platform that further enhances the realism of virtual samples.

This month, the circular knitting machine manufacturer Mayer & Cie. is launching its upgrade kits for circular knitting machines that are already successfully in use by customers. With tailor-made packages, the company wants to give its users the opportunity to take advantage of technological progress in their existing machines. The aim is to improve the performance of the existing machines and to extend their service life. In addition to the machine-specific upgrade kits, the company now starts offering tailormade spare parts packages. They are intended to ensure machine availability and equip customers with spare parts for standard situations. In addition, they offer a degree of independence from possible failures in the supply chain and rising transport costs.

Longevity, a popular product property
“Longevity of our circular knitting machines is definitely a property that our satisfied customers mention regularly”, Mayer & Cie. sales director Wolfgang Müller says. The company estimates that up to 50 percent of all the circular knitting machines it has ever made are still around in the market somewhere.

Upgrades boost performance and value
Value retention, maintenance and upgrades for existing machines are a key issue for the company – and for the customers who successfully use existing Mayer & Cie equipment. That’s why the company recently launched customised upgrade kits to improve the long-term performance of machines.

Low budget, clear benefit
Compared to a new machine, upgrade kits are a low-cost investment that deliver clearly defined benefits. For example, an improved yarn guide ensures a significant increase in the plating reliability and output of the machine in question.

Most of the upgrade kits is machine-specific; the aforementioned yarn guide ensures a boost in productivity for the Relanit 3.2 II and Relanit 3.2 S. For S4 machines an optimised fluff blowing device can be the solution. It ensures that less fluff is knitted in and thereby improves the fabric quality. It also reduces downtimes that would otherwise be required for cleaning. Upgrade kits suitable for most Mayer & Cie. machines are the edge trimmer to open a fabric hose before the fabric’s rolling-up and the laying facility for high-quality hose fabric.

Spare part packages: Inside is what is required
In addition to individual upgrade kits Mayer & Cie. now offers spare parts packages. They too are customised for individual machines. When purchasing a machine, the customer can also order a small or a large spare parts package. Selected specially for the machine in question, it contains the most important consumables and spare parts.
The new spare parts packages also increase customers’ independence of supply chain failures and rising transport costs.
