Engineered Yarns
ENGINEERED YARNS
High-performance technical textiles
Our broad portfolio of engineered yarns is used in a wide range of applications. Most of our technical yarns are customized to meet the requirements of certain downstream processes and end uses.
Textile yarns are often used as reinforcement materials in mechanical rubber goods (MRG) In textile reinforced rubber products, the textile yarn provides properties such as tensile strength and rigidity. For rubber applications, we treat our yarns with RFL dips (Resorcinol Formaldehyde Latex) or with our RF-free MSA treatment (MEHLER SUSTAIN ADHESIVE) to achieve the required level of adhesion between the specific type of rubber and the specific type of yarn.
Beyond the wide product field of engineered yarns for rubberized products, we also produce customized untreated engineered yarns and specialty yarns for niche markets.
SOFT CORDS
low stiffness and soft haptics
Soft cords are made from raw yarns such as polyamide, polyester, aramid, polyvinyl alcohol (PVA) and viscose. The raw yarns are twisted or twisted and dipped in water-based substrates to achieve adhesion to various rubber compounds.
Available water-based finishes are the RF-free finishing technology MSA (Mehler Sustain Adhesive) or traditional RFL dips (resorcinol formaldehyde latex). An additional dip may be required in advance for high adhesion requirements.
Soft cords are characterized by a soft feel and low rigidity.
The finished soft cords are mainly used in tires, hoses, air springs, rubber couplings, seals and profiles. Soft cords for tire cords, for example, reinforce the tire structure and maintain functionality under changing external conditions over the entire service life of a tire.

STIFF CORDS
high tensile strength and stiffness
Stiff cords are twisted yarns made of raw yarns polyamide, polyester, aramid and also carbon, glass or polymers like rayon or PVA.
After twisting, the threads are impregnated with solvent-free or solvent-based treatments to generate stiffness or cut resistance. In this step, filaments of the single yarn are glued into the twisting system. The second impregnation step is a water-based RFL-dip to achieve sufficient adhesion between the cords and various rubber types. For some high-performance applications, an additional overcoating (OC) step may be used, e.g. to withstand greater dynamic forces or to create additional adhesion.
Stiff cords are mainly used for V-belts, timing belts and other drive belt applications.
