Groz-Beckert (Hall 3.0, Booth F03)

Groz-Beckert will be at the Techtextil presenting its comprehensive product portfolio and service offering.

In Knitting, Groz-Beckert is presenting its product portfolio for the technologies circular knitting, warp knitting and flat knitting, as well as customer-specific solutions. With system solutions from a single source, the company is responding to more stringent requirements for wear, load capacity of key components and the workability of different materials.

The Weaving department is presenting its comprehensive range of products for weaving preparation and weaving accessories. A highlight of the portfolio is the PosiLeno leno system, which boosts efficiency by up to 100%. Moreover, an acrylic weaving machine mock-up, the WeavingLoom, will provide insight into the operation of heald frames, healds, warp stop motions and drop wires.

The jacquard heald is also demonstrated using the WeavingLoom. Made of mono wire, this product facilitates not only high densities but also a particularly gentle workmanship. In combination with the innovative thread eye, which is glued into the mono wire instead of welded, Groz-Beckert provides for uniform fabric quality and high machine efficiency.

With its product area Felting the company puts its contribution to the nonwovens industry on display. The service life and rust resistance of felting and structuring needles have been, and are, important issues in nonwoven manufacturing.

Now, Groz-Beckert is presenting its latest innovation: Groz-Beckert dur. The patented manufacturing process of the needles in combination with a new base material improves resistance to corrosion with up to 30%% longer service life. Moreover, the staple fiber needle punch line inaugurated in March in the Technology and Development Center at company headquarters in Albstadt is going to be presented.

For Spunlance customers, the company is presenting another new product with its HyTec jet strips. As well as improved handling properties, the innovative jet strips also feature significantly higher hardness, which has a positive effect on all mechanical properties such as scratch resistance, bending strength and service life.

The Carding department's focus at the show is on improved performance and on raw material savings and is presenting the high-performance worker and doffer wires SiroLock and EvoStep.

EvoStep card clothing features a unique slanted step undercut on the tooth front. In this area the working angle is significantly more pronounced than in conventional worker and doffer wires.

Compared to EvoStep card clothing, which aims to reduce raw material consumption, the focus of SiroLock card clothing is on boosting performance of the roller card via high delivery rates and nonwoven weights.

Presenting the Quality Management INH (Ideal Needle Handling) at this year’s Techtextil, the area of Sewing is waving the banner of process optimization. The patented process provides support in the handling of sewing machine needles during the entire sewing operation and has recently also been offering a digital solution to document needle breakage: the Smart INH.

The documentation system consists of two pieces of software, a mobile app and a browser, thereby facilitating the digital saving and storage of data sets as potential evidence. The Mobile Lab will be another Sewing highlight. It allows material samples to be examined and analyzed directly at the Groz-Beckert booth.

Jakob Müller （Hall 3.0, Booth B19）

Jakob Müller will be presenting three key exhibits at Techtextil 2017, namely the NH2 53 2/130 S2 narrow fabric loom, COMEZ ACOTRONIC 8B/600 crochet knitting machine and UV60-W automatic cutting and winding device.

NH2 53 2/130 narrow fabric loom:

The electronically controlled NH2 53 2/130 narrow fabric loom offers virtually unlimited repeat lengths. It will be shown producing a bag tape with woven-in drawstring.

As a result of the electronic shed formation possessing patterning possibilities employing up to sixteen electronically controlled heald shafts, a variety of bags in differing sizes can be produced on every machine space. Mechanically controlled machines do not possess this capability.

The bags can be used to carry tools or small components for assembly purposes. The drawstring is woven in during the weaving process, which means that an additional make-up phase is unnecessary.

The production costs of the machine are considerably lower owing to its energy requirement of less than 2kW, limited maintenance requirement and reduced need for spare parts, as only a few mechanical parts are employed.

COMEZ ACOTRONIC 8B/600 crochet knitting machine:

This is a high-efficiency, electronic crochet knitting machine that employs compound needles for the production of a wide range of ribbons, technical and medical textiles, both elastic and non-elastic.

Compound needles make the machine highly versatile, as in addition to classic synthetic yarns (polyester, polyamide) they allow the processing of natural yarns (cotton, wool) and special fibres (Kevlar, fibre glass, carbon, basalt) in the warp.

A supplementary warp tube bar with electronic drive (BPO/STR-600) can be supplied on request. This has an electronic drive that allows the creation of various knit constructions in the warp (open lock-stitch, closed lock-stitch, etc.) that lend the fabric a lock-stitch character. More complex knit constructions (e.g. double lock-stitch) are also possible using the BPO/STR-600 together with the standard warp bar, which is driven by special cams (TRICOT/S).

The electronic drive applied to the feeders and the finished product take-off provides the possibility of varying stitch density values (stitches/cm) in a single product, as well as different values for weft/warp feeding and elasticity.

The COMEZ ACOTRONIC 8B/600 is fitted with the colour touch screen DATA CONTROL CONTROLLER, which manages all essential machine functions, monitors production data and enables the realisation of lengthy pattern repeats.

A very interesting new feature of this machine is a special embroidery device which allows sewing weft yarns into a ground fabric.

UV60-W automatic cutting and winding device:

The device is designed for the make-up of medium-weight and heavy, non-elastic belts. Coreless rolls are wound from the start of the belt and the end can be fixed with a metal clip. Rolling from the middle of the belt is also possible with the result that both belt ends are free for further processing. The machine is also suitable for the cutting of belts to length alone.

At the fair, the machine will be shown for the first time with a new five-compartment tool changer. The tools sit on a rail and are quickly and precisely positioned over the belt using SPS control. As a result, the UV60 offers a vast range of make-up possibilities.

Karl Mayer (Hall 3.0, Booth E18)

Karl Mayer’s presentation at Techtextil will be “Textile-reinforced concrete”. As introduced, visitors can expect an impressive display focusing on textile-reinforced concrete and functional clothing for the sports and athleisure sectors.

Textile reinforcing materials offer better ecological and economic alternatives to steel reinforcements when building with concrete, according to Karl Mayer. Since textiles do not rust, only a thin covering material is required. This saves on resources, reduces environmental pollution and also enables thin-walled, filigree designs to be produced.

Karl Mayer Technische Textilien GmbH (Technical Textiles) can offer the RS MSUS-G weft-insertion warp knitting machine for producing the textiles that are used as an innovative way of reinforcing concrete. This high-speed raschel machine with weft insertion in line with the stitch courses can produce heavy carbon-fibre grids, which are used by members of TUDALIT e.V.

The textiles produced on the machines manufactured by Karl Mayer Technische Textilien can be used to reinforce the composite materials used in concrete construction, as well as plastic composites.

According to Jochen Schmidt, the Managing Director of Karl Mayer Technische Textilien GmbH, the concept of fibre spreading is also starting to be a hot topic. Before they are joined to the plastic matrix, the fibre tapes are spread using Karl Mayer’s UD 500 and UD 700 fibre spreading machines. These two machines have already made a name for themselves among composites’ manufacturers for use in the preliminary stages in the production of multiaxial textiles.

For innovative sports- and athleisure-wear sector, stylish, functional stretch and non-stretch textiles are speciality of Karl Mayer’s warp knitting machines. The company’s high-speed tricot machines, jacquard raschel machines and double-bar raschel machines can produce a variety of structured and openwork designs from a single source, and also work functional zones that can be integrated into a garment, such as a jersey.

Zones are created, which provide a defined compression, breathability, warmth retention and freedom of movement. This is based on body mapping principles and the zones are located in exactly the right places. KARL MAYER’s double-bar raschel machines in particular are also setting functional trends when producing seamless items that are making quite a fashion statement.

MESDAN (Hall 3.0, Booth B08)

The Italy based Mesdan S.p.A. will present the new LINEAR CUT RESISTANCE tester, for the assessment of the resistance to the linear cut of gloves and protective cloths, as per the EN ISO 13997 and the EN 388, endowed with a system for adjusting the cutting pressure and a multi-position sample holder.

The EN 388 was recently revised and it now demanding the use of 2 equipment, both in the Mesdan-Lab rage: the new LCR tester (so called “tomodynamometer”), particularly required for the high resistance materials, and the “round blade” cut tester for the regular/light.

Additionally, Mesdan represents the US based THERMETRICS, manufacturer of equipment for the measurement and evaluation of thermal comfort of fabrics, garments, protective apparel, as well as for the automotive industries, such as the Dry and Sweating Guarded Hotplates, thermal, sweating and flame test manikins, and flame/radiant test devices.
