Abstract RU 2709038 C1

FIELD: manufacturing technology.

SUBSTANCE: disclosed are elastic materials and absorbent products containing resilient materials. In the version of implementation, elastic material may contain the first layer connected to the second layer by means of the first links and the second links. Plurality of elastomer threads can extend between first layer and second layer. First link and second link are located on opposite sides of first thread and are spaced from each other at longitudinal distance, which is less than diameter in non-drawn state of first thread, and the third bond and the fourth bond are located on opposite sides of the second thread and are spaced from each other at a longitudinal distance which is less than the diameter in the non-stretched state of the second thread. First link forms the first angle relative to the first thread, the third link forms the second angle relative to the second thread, and the first angle differs from the second angle.

EFFECT: disclosed elastic materials stretching in a certain direction.
