In the Fiat-Lancia 50441 standard, published jointly by Fiat automobile company and its affiliate Lancia automobile company, the requirements for the sewing tensile properties of fabric, leather and artificial leather materials used in the interior of automobiles are explained and a test method is defined.
There are many different types of upholstery fabrics for vehicles, but there are two that are most commonly used. The first is leather upholstery fabrics, as well as materials that look like leather or are designed to function like leather. However, fabrics produced by tightly woven fibers are more preferred in terms of quality and performance conditions.
Car interiors, especially the seats, have to be relatively durable to sustain years of use inside and outside the car.
Leather and artificial leather materials are widely used in car upholstery due to their durable and pleasant appearance. Leather material comes in a wide variety of colors and is generally preferred because it is waterproof.
Whether it is fabric, leather or artificial leather, the most important factor affecting the quality and performance of upholstery is its seam retention.
For car seats, industrial textiles not only cover the underlying foam but also increase the firmness of the seat cushion and influence the viscoelastic ( adhesive and flexible substance) behavior of the foam. Furthermore, the strength of the seams is one of the main quality parameters. Not only the strength properties of the materials and threads but also the performance of the seams are important. One of the most important quality factors related to seams is the type of fabric. Car seat upholstery uses woven, knitted, and non-woven fabrics, as well as natural and artificial leather and synthetic fibers derived from synthetic polymers such as polyester, polyamide, and viscose, along with blends of wool and cotton.
In advanced laboratories, the stitching properties of all kinds of upholstery fabrics are determined within the framework of the Fiat-Lancia 50441 standard.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides sewing tensile testing services for fabrics, leathers and artificial leathers, within the scope of Fiat-Lancia 50441 standard, with its trained and expert staff and advanced technological equipment.
