New mattresses made of industrial & post-consumer foam waste

  • Recypur successfully starts up a complete airlay line delivered by ANDRITZ for its mill in L’Alcúdia, Spain

The airlay line is designed for recycling of post-industrial and post-consumer foam and was developed specifically for the bedding and furniture industry, with material heights reaching 20 cm and densities of up to 120 kg/m3. Experimental tests carried out together with experts from ANDRITZ Laroche led to the conclusion that the mechanical method for recycling polyurethane is the most versatile and reliable.

With a capacity of 1.2 t/h, this airlay line enables Recypur to supply new mattresses made of industrial & post-consumer foam waste from old mattresses. This well proven process allows to reduce the environmental impact, increase self-sufficiency and eventually reduce the use of polyurethane. Such a set-up also allows multiple functional materials to be incorporated into the blend, such as flame-retardant, conductive and insulating fibers, among others. Thanks to this tailored approach, Recypur is now able to expand its diversification, innovation and reputation on the Spanish market.

Swiss Textile Machinery technology and innovations for technical textiles

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.

BRÜCKNER successful in Turkey with stenters

The Turkish company ARIKAN Mensucat Industry and Trade Inc. was founded in 1993 and is located in Kahramanmaraş, one of the southernmost cities of the country. Today, the family-owned company employs around 1,500 people and finishes around 55 tons of knitwear every day. In addition to many well-known Turkish fashion manufacturers, ARIKAN also supplies international manufacturers in Europe, Russia, the Gulf States and other leading international markets.

The Turkish company ARIKAN Mensucat Industry and Trade Inc. was founded in 1993 and is located in Kahramanmaraş, one of the southernmost cities of the country. Today, the family-owned company employs around 1,500 people and finishes around 55 tons of knitwear every day. In addition to many well-known Turkish fashion manufacturers, ARIKAN also supplies international manufacturers in Europe, Russia, the Gulf States and other leading international markets.

The German machinery manufacturer BRÜCKNER supported the Turkish company from the very beginning. From the foundation of the dyeing and finishing plant, BRÜCKNER supplied three stenters for the finishing of the high-quality knitted fabric in 2014. Two more lines followed in 2016. For decades, BRÜCKNER has been the market leader for the finishing of knitted fabric. Especially for very fine and elastic fabric, special line configurations and technological know-how are necessary to be able to produce a high-quality end product. During the drying and heat-setting process, for example, extremely accurate and uniform temperature distribution over the entire length and width of the dryer is essential. In the BRÜCKNER stenter this is achieved, among other things, by the alternating arrangement of the thermal zones every 1.5 meters and by the proven split-flow air system.

The machine operators at ARIKAN appreciate the easy control of BRÜCKNER lines. The visualization is intuitively designed and offers many auxiliary systems for an optimized production process. In addition, significant energy savings can be achieved with just a few changes to the machine parameters.

The management at ARIKAN attaches great importance to energy saving, especially in the fabric finishing department. The drying process is one of the most energy-intensive in the entire process chain, therefore the biggest savings can be made here. These have a direct impact on the manufacturing costs of the textiles and thus on competitiveness in the market. In the meantime, talks are already in progress for another BRÜCKNER line which will include a very special feature: a combined heating system for the dryer. For many customers - and so also for ARIKAN in Turkey - e.g. steam energy is available free or very cheap. With the combined heating system developed by BRÜCKNER it is possible to use this steam energy for heating up the dryer and thus to achieve significant savings. If the available steam is not sufficient for a running process, it is automatically switched over to gas heating. This mode of operation does not only have an effect on the energy costs, but also makes a considerable contribution to environmental protection.
