  "description_excerpt": "This application is the U.S. national phase of International Application No. PCT/EP2013/064932 filed 15 Jul. 2013 which designated the U.S. and claims priority to EP 12176778.4 filed 17 Jul. 2012, the entire contents of each of which are hereby incorporated by reference.\n\nThe invention relates to an abrasion resistant product comprising a plurality of interlaced yarns wherein at least a first yarn has a tensile strength, having a value TS in N/tex, said yarn containing a plurality of UHMWPE fibres having a titer, having a value T in den.\n\nProducts comprising a plurality of interlaced yarns, such as ropes, slings and nets are continually developed to meet the needs of high performance applications. Such developments are mainly concerned with adapting materials used in said products and/or construction methods thereof. Plenty of data analyzing the influence of the tensile strength of yarns on various properties, e.g. abrasion resistance, of products containing thereof, showed that by increasing said strength, the abrasion resistance seems to increase also. Hence, in the field of products having abrasion resistance, in particular high end ropes and slings, a common understanding has been developed in time that the use of high tensile strength yarns, e.g. polyethylene yarns such as those known as Dyneema®, provide improved abrasion resistance.\n\nFor example EP1973830 discloses a roundsling comprising a core rope and a cover woven from SK75 1760 dtex yarn sold by DSM Dyneema® (NL), a high strength ultrahigh molecular weight polyethylene (UHMWPE) yarn with a strength of about 3.5 N/tex and a fiber titer of about 2 den.",
