Product and application
Stabilising weft yarns ("Tabby" yarns) for the production of tire cord, a fabric that is incorporated into car tires. |
|
|
Meets all customer requirements
Tire cord fabric needs to have a very specific width. Anything outside this specific width is seen as waste material and should be reduced to a minimum. However it is very difficult to keep the fabric to the required width in light of the facts that the basic material is synthetic, it is kept under tension over a great amount of the length and undergoes temperature variances during the process. Therefore the weft yarn used in the fabric needs to have the following features: |
|
|
 |
|
Dimensionally stable / low shrinkage allowance |
|
 |
|
Demand: The weft yarn should hold the fabric at a specific width and guarantee a low shrinkage in spite of the elasticity of the warp yarn, the tension of the fabric and the alternating temperature |
|
|
|
Solution: The yarn has a core of glass which guarantees a low shrinkage allowance |
|
|
|
|
Textile character |
|
|
|
Demand: The yarn should not disrupt the production efficiency of the weaving process |
|
|
|
Solution: A sheath of fibre material that is spun around the glass core ensures a textile character that enables efficient weaving |
