• Swiss weaving machinery manufacturers are in the forefront of novel application development

Shoes and electronic calculators are probably not the first products people would associate with the textile weaving process. But they certainly signpost the future for woven fabrics, as two examples of the ever-wider possibilities of latest technology in the field. Fashion and function already combine in the increasing popularity of woven fabrics for shoes, and this is a present and future trend. Calculators in fabrics? That’s another story of ingenious development, using so-called ‘meander fields’ on the back and keys printed on the front of the material.

These glimpses of the outlook for modern weavers are among the highlights of developments now being pioneered by Swiss textile machinery companies. All weaving markets require innovation, as well as speed, efficiency, quality and sustainability. Member firms of the Swiss Textile Machinery Association respond to these needs at every point in the process – from tightening the first thread in the warp to winding the last inch for fabric delivery. They also share a common advantage, with a leading position in the traditional weaving industry as well as the expertise to foster new and exciting applications.

Technology and research cooperation
The concept of a ‘textile calculator’ was developed by Jakob Müller Group, in cooperation with the textile research institute Thuringen-Vogtland. Müller’s patented MDW® multi-directional weaving technology is able to create the meander fields which allow calculator functions to be accessed at a touch. A novel and useful facility, which suggests limitless expansion.

Today, the latest woven shoes are appreciated for their precise and comfortable fit. They score through their durability, strength and stability, meeting the requirements of individual athletes across many sports, as well as leisurewear. Stäubli is well known as a leading global specialist in weaving preparation, shedding systems and high-speed textile machinery. Its jacquard machines offer great flexibility across a wide range of formats, weaving all types of technical textiles, lightweight reinforcement fabrics – and shoes.

It’s possible to weave new materials such as ceramics, mix fibers such as aramid, carbon and other, and produce innovative multi-layers with variable thicknesses. Such applications put special demands on weaving machines which are fulfilled by Stäubli high-performance TF weaving systems.

Great weaving results are impossible without perfect warp tension, now available thanks to the world-leading electronic warp feeding systems of Crealet. Some market segments in weaving industry today demand warp let-off systems which meet individual customer requirements. For example, the company has recognized expertise to understand that geotextile products often need special treatment, as provided by its intelligent warp tension control system. Individual and connective solutions are designed to allow external support via remote link. Crealet’s warp let-off systems are widely used in both ribbon and broadloom weaving, for technical textiles applied on single or multiple warp beams and creels.

Functional, sustainable, automated
Trends in the field of woven narrow fabrics are clearly focused on functionality and sustainability. The Jakob Müller Group has already embraced these principles – for example using natural fibers for 100% recyclable labels with a soft-feel selvedge. It also focuses as much as possible on the processing of recycled, synthetic materials. Both PET bottles and polyester waste from production are recycled and processed into elastic and rigid tapes for the apparel industry.

For efficient fabric production environments, it is now recognized that automated quality solutions are essential. Quality standards are increasing everywhere and zero-defect levels are mandatory for sensitive applications such as airbags and protective apparel.

Uster’s latest generation of on-loom monitoring and inspection systems offers real operational improvements for weavers. The fabric quality monitoring prevents waste, while the quality assurance system significantly improves first-quality yield for all applications. Protecting fabric makers from costly claims and damaged reputations, automated fabric inspection also removes the need for slow, costly and unreliable manual inspection, freeing operators to focus on higher-skilled jobs.

Smart and collaborative robotics (cobots) offer many automation possibilities in weaving rooms. Stäubli’s future oriented robotics division is a driver in this segment with first effective installations in warp and creel preparation.

Control and productivity
Willy Grob’s specialized solutions for woven fabric winding focus on reliable control of tension, keeping it constant from the start of the process right through to the full cloth roll. Continuous digital control is especially important for sensitive fabrics, while performance and productivity are also critical advantages. In this regard, the company’s large-scale batching units can provide ten times the winding capacity of a regular winder integrated in the weaving machine.

The customized concept by Grob as well as design and implementation result in great flexibility and functionality of the fabric winding equipment – yet another example of Swiss ingenuity in textile machinery.  
There is even more innovation to come in weaving – and in other segments – from members of the Swiss Textile Machinery Association in future! This confident assertion is founded on an impressive statistic: the 4077 years of experience behind the creative power of the association’s member firms. It’s proof positive that their developments grow out of profound knowledge and continuous research.

Attendees of the May 19-22 National Restaurant Show in Chicago learned that linen, uniform and facility services providers serving restaurants and other foodservice operations can be distinguished by earning third-party verification of their sustainability and cleanliness, as TRSA exhibited its Clean Green and Hygienically Clean Food Service certifications at the show.
More than 150 individuals viewed the exhibit, which screened a new animated video explaining the Clean Green designation. It’s now showing on TRSA’s YouTube page (https://www.youtube.com/watch?v=I-24iVCNRT0).

Depicting operations within a laundry, the video shows how contracting with a Clean Green certified provider delivers services restaurants need and gives them peace of mind from doing business with a sustainable provider. Clean Green operations comply with water and energy standards and demonstrate best management practices in supplying, laundering and maintaining textiles.

Visitors to the exhibit learned which providers serving these attendees’ home geographic areas are Clean Green certified and were encouraged to work with such a certified provider if not already doing so. Speaking with attendees also gave TRSA staff the opportunity to ask them about their experience with providers and, if currently under contract with one, its identity.

• 76 percent of those questioned indicate they currently use such a provider. Most could identify it by name
• 18 percent said they use an on-premises or home laundry for linen and uniform needs. Many of these respondents indicated they work for hotels, healthcare facilities, colleges or military bases with their own laundry equipment
• 6 percent said they use disposable products (napkins, wipers) instead of their reusable textile equivalents; most of these respondents are in quick-service restaurant operations

The TRSA display distributed copies of Sustainability: Finding the “New” Green in Your Restaurant Supply Chain, a 7-page guide to using a systematic approach to choose suppliers whose products/services are proven to be more sustainable than those of their competitors and whose own practices are more sustainable.

TRSA’s exhibit also kicked off a survey of restaurant management to determine their perceptions of table linen service as a plus for facility hygiene and service to diners. Results will help TRSA communicate to the restaurant industry the value of using Hygienically Clean Food Service certified providers in the hope that doing so becomes an industry standard.

Such certified laundries commit to cleanliness through third-party, quantified biological testing and inspection. This process eliminates subjectivity by focusing on outcomes and results that verify linens and uniforms cleaned in these facilities meet appropriate hygienically clean standards and best management practices for servicing full- and limited-service restaurants, hotels, hospitals, educational institutions and other locations where food is handled and served.

ABOUT CLEAN GREEN
Clean Green certification recognizes linen, uniform and facility services companies that demonstrate responsible leadership in sustainability and conservation by acknowledging commitment to improving water and energy efficiency and adoption of best management practices for reusing, reclaiming and recycling resources. Certified operations meet quality standards for effectiveness in conserving resources and minimizing environmental impact. Customers that use Clean Green certified companies to supply, launder and maintain linens, uniforms, mats and other reusable textiles can be assured that their provider maximizes sustainable practices.

ABOUT HYGIENICALLY CLEAN
Hygienically Clean certification demonstrates linen, uniform and facility services companies’ commitment to cleanliness through independent, third-party laundry plant inspection and quantified microbial testing. Inspection and re-inspection verify that items are maintained, washed, dried, ironed, packed, transported and delivered using best management practices to meet key disinfection criteria. Between scheduled and supplemental inspections, ongoing microbial testing quantifies cleanliness and indicates laundry process adjustments.
