Sewing machine needles for leather and technical textile
Animal skins have been made into leather for thousands of years. Leather was first used as clothing and in living quarters to ward off cold and other outside influences. Most of the leather made in the world today is used to produce footwear, but the hard-wearing material is also employed in the automotive and furniture industries.
The processing of technical textiles – that is, all textile-based products made primarily for their technical and functional properties and not for aesthetic or decorative purposes – has played a role in the textile world for only a few decades. The special requirements of this sector, such as the sewing of special materials or material combinations, also place high demands on production.
Sewing machine needles from Groz-Beckert provide many benefits when working with leather and technical textiles. Different cutting and cloth points, special application needles tailored to need, and innovative manufacturing methods lead to high reliability and flawless sewing results.
Special application needles SAN™ 5.2
For the processing of technical textiles
Processing technical textiles often involves extremely hard materials or combinations of material. Penetration resistance can be very high and lead to various problems.
Groz-Beckert has been supplying the SAN™ 5 special application needle for years, a reliable product that reduces sewing problems when working with technical textiles. The upgraded SAN™ 5.2 boosts process reliability even more and delivers additional advantages, especially for multi-directional sewing applications.
The double groove at the point, for instance, leads to better thread guidance for a more consistent seam pattern. The additional scarf chamfer on the left side enables secure loop pick-up using oscillating hooks.

Special application needle SAN™ 12
For perfect 2-needle decorative seams
Varying and irregular seams are among the problems known to crop up on 2-needle machines. Yet when manufacturing high quality leather products, high value is placed on the perfect pattern of fancy seams.
Irregular seams are caused by the different threading directions and loop pick-up of the left and right needles. Groz-Beckert has developed the special application needle SAN™ 12 to improve the appearance of these 2-needle decorative seams.
This is achieved by exactly orienting the cutting geometry via a special flat on the shank. The two seams are matched for a more consistent appearance.

For creating different seam patterns on leather
Because of the structure of leather seam patterns vary, depending on sewing direction, when sewing with a cloth point. Leatherworking thus requires the use of a cloth point which produces a consistent seam pattern in all sewing directions. Groz-Beckert offers a wide variety of cutting points to allow for different seam appearances. Whether it's the LR point for seams oriented to the right, the P point for marked fancy effects, or the S point for straight seams – creativity knows no bounds.

The titanium nitride coating
Demanding sewing processes, such as the stitching of hard materials or combinations of materials, often lead to premature wear of sewing machine needles.
The special GEBEDUR™ coating from Groz-Beckert gives the needle surface a higher degree of hardness. The titanium nitride coating makes the needle more wear-resistant, particularly protecting against damage around the point and eye. This extends the service life of the needle, ultimately leading to consistently high seam quality and increased productivity.

Processing of leather
For many years, leather has been used as the raw material for very different products. Nowadays goods such as clothing and shoes are made of it, but also furniture and the interior trim of vehicles.
For several decades, leatherworking and leather manufacture have been shaped by globalization. Much of the industry has relocated from Western countries to areas like China and India. This is due, on the one hand, to increased labor costs in Western countries and, on the other, to the large role played by environmental specifications, since they are particularly relevant to the leather industry.
When it comes to innovation, process optimization stands front and center in the leather industry The goal is sustainable leather manufacture while diminishing the use of chemicals. Beyond that the development of products such as thinner and lighter leather, which nevertheless maintains the same physical properties of traditional leather, is in the works.
Learn more about the properties and processing of leather in our brochure Sewing machine needles for leather and technical textiles.
Technical textiles comprise all textile-based products manufactured primarily for their technical and functional properties, and not just for aesthetic or decorative purposes.
The manufacture of technical textiles into finished end products has been an important application area for the sewing industry. The special materials and different material combinations pose a major challenge to the manufacturing process.
Steady growth and an especially high rate of innovation distinguish the technical textiles market. Technical textiles currently comprise 25% of global textile production. Growth is spurred by consistently capturing new application areas and by developing new manufacturing processes.
Groz-Beckert knows these challenges and, by developing and improving special sewing machine needles (for instance the SAN™ 5.2), provides the appropriate products for working with technical textiles.

High quality standards
For both leather products and technical-textile products, product quality and often safety are priority.
Since the special materials in both areas make high demands on the manufacturing process, flawless source materials must be employed. Yet application problems such as damage to material or sloppy and hence insecure seams cannot always be prevented.
The specially designed sewing machine needles from Groz-Beckert help decrease or prevent these application problems. In some cases, however, using these needles is not enough - the right machine setting and using the appropriate sewing thread also play an important role.
