Soft cord

Soft cord is twisted or threaded raw yarn which is coated with one or several substrates to create adhesion to rubber mixtures. Primary features are soft haptics, low stiffness and the water-based chemical system.


Stiff cord

Stiff cord is twisted yarn which is impregnated with solvent-free or solvent-based fittings. Multi-layer systems are possible as well. The pre-dip ensures a rigidity or cut resistance defined by the customer and results to the filaments of the individual yarn being glued in the twist system.


Specific yarn

Specific yarn by MEP represents a significant expansion of our portfolio, adding to our familiar product range of raw materials, fibers and rubber-friendly fittings. We are open for any type of request regarding new raw materials and fibers and also offer coating and fitting services with alternative substrates.


Untreated yarn

Untreated yarn are fiber raw materials which are twisted up as yarn or twisted together as thread. Typically, this technical yarn is not coated. We use different materials in various presentations to manufacture twisted yarn and thread.


Soft cord, stiff cord and other technical yarn at MEHLER ENGINEERED PRODUCTS

As reinforcing materials, our technical yarns influence different functions of the final product. Those functions include size modifications under operational conditions, bursting strength as well as tensile strength and elasticity in longitudinal direction. Rubber-friendly fitted yarns are used in air condition, brake, hydraulic and fuel hoses, toothed belts, fan belts and other drive belts as well as various tires and air springs. The adhesion of the yarn to the rubber creates synergy effects between the textile and rubber in the final products. Low strength and partially low e-modules represent significant weaknesses of rubber in applications in technical items. The required properties of the final product can only be achieved through the combination with textile reinforcing materials, meaning the technical yarn by MEP. The selection of the coating follows the type of rubber as it is what creates the adhesion between textile and rubber. Coating is generally done using RFL dips, which consist of latex, a resorcinol pre-condensate and formaldehyde dissolved in water or other solvents. The fiber raw material is generally selected in accordance with the mechanical requirements of the final product. Polyester (PES) creates a high degree of strength in combination with high shrinking forces and low elasticity. Polyamides (PA) create a high degree of elasticity while aramids (AR) will lead to high strength with low elasticity.
