1. A chain comprising at least two interconnected chain links, wherein
the chain links comprise a strip of fabric comprising weft yarns and warp yarns, the warp yarns comprising a warp yarn A and a warp yarn B, wherein each of the warp yarns A and the warp yarns B comprise a plurality of polyolefin filaments having a tenacity of at least 1.2 N/tex and a minimum creep rate being measured at a tension of 900 MPa and a temperature of 30° C., wherein the minimum creep rate of the warp yarn B is higher than the minimum creep rate of the warp yarn A, such that a ratio of the minimum creep rate of the warp yarn B to the minimum creep rate of the warp yarn A is at least 2, and wherein
the strip comprises a longitudinal core section and at least two longitudinal edge sections adjacent to and facing laterally outwardly from the core section such that the core section is located between the longitudinal edge section in the strip, wherein each of the longitudinal core section and the at least two longitudinal edge sections have respective concentrations of the warp yarn A and the warp yarn B, and wherein
the warp yarn A is present in the longitudinal core section in a concentration which is higher than the concentration of the warp yarn A in the two longitudinal edge sections of the strip, and wherein
the warp yarn B is present in the two longitudinal edge sections in a concentration which is higher than the concentration of the warp yarn B in the longitudinal core section of the strip.
