The self-winding fiber adhesive tape for wrapping cables, comprises band shaped carrier (2) and an adhesive layer (3) applied on a side of the carrier, which consists of a fiber having predominant filaments that extend itself one side as longitudinal fiber (5) in longitudinal direction of the tape and another side as transverse fiber (6) with a fiber density of 28 fibers per centimeter length in transverse direction of the tape. Yarn count of the longitudinal fiber related on the width is 2600 dtex/cm and the transverse fiber related on the length is 4700 dtex/cm. The self-winding fiber adhesive tape for wrapping cables, comprises band shaped carrier (2) and an adhesive layer (3) applied on a side of the carrier, which consists of a fiber having predominant filaments that extend itself one side as longitudinal fiber (5) in longitudinal direction of the tape and another side as transverse fiber (6) with a fiber density of 28 fibers per centimeter length in transverse direction of the tape. Yarn count of the longitudinal fiber related on the width is 2600 dtex/cm and the transverse fiber related on the length is 4700 dtex/cm. The longitudinal and transverse fibers are externally fixed relative to each other against a displacement through the adhesive layer, through the use of texturizing yarns as longitudinal and transverse fibers, through calendering of the carrier, through an additional acrylate or polyurethane coating of the carrier, through a size of the carrier or through an intermingling of the smooth and texturizing fibers. The fixing of the fibers is increased by the intermingling. The fiber density of the longitudinal fiber is 30-50 fibers per centimeter width and the transverse fiber is 30 fibers per centimeter length. The yarn count of the longitudinal fiber related on the length is 2950 dtex/cm and the transverse fiber related on the length is 5200 dtex/cm. The strength of the longitudinal fiber is 80-100 dtex. The fibers are multifilament fibers and are combined together with different fiber numbers. The longitudinal fiber consists of 22-26 filaments per fiber and the transverse fiber consists of 34-38 filaments per fiber. The fibers are smooth and/or texturized. The intermingling grade of the threads is 80-100 intermingling points per running meter. The fiber of the carrier has a surface weight of 73-77 g/m 2>. The adhesive is synthetic rubber adhesive or acrylate adhesive. The adhesive layer is applied with a specific surface weight of 40-70 g/m 2>. The top of the carrier is sealed with an acrylate layer. The tap has a thickness of 0.16-0.22 mm, a minimum dielectric strength of greater than 1000 V, ultimate elongation of 15-25%, tensile strength of 65-105 N/cm and a winding power of 3-7 N/19 mm. The abrasion level of the tap is in accordance with LV312 in the measurement to a thorn with 10 mm diameter. The adhesive strength at the tape ridge is 4-7 N/cm and at the steel is 5-11 N/cm. |
