Claim:
1. A method comprising: causing, by a device, a first roll and a second roll to apply a plurality of elongation levels on a first portion of a yarn provided between the first roll and the second roll, receiving, by the device, a plurality of tension measurements associated with the first portion of the yarn, based on applying the plurality of elongation levels on the first portion of the yarn; determining, by the device, whether the plurality of elongation levels satisfy thresholds based on the plurality of tension measurements; adjusting, by the device, a roll speed of the first roll or the second roll when at least one of the plurality of elongation levels fails to satisfy at least one of the thresholds; causing, by the device, the second roll and a third roll to apply a constant tensile force on a second portion of the yarn provided between the second roll and the third roll; receiving, by the device, diameter measurement information associated with the second portion of the yarn based on applying the constant tensile force on the second portion of the yarn and based on applying the plurality of elongation levels on the first portion of the yarn; determining, by the device, a quantity of entanglements in the yarn, associated with each elongation level, of the plurality of elongation levels, based on the diameter measurement information; and determining, by the device, an entanglement strength of the yarn, associated with each elongation level, of the plurality of elongation levels, based on the quantity of entanglements in the yarn associated with each elongation level.
