In this study,teststheyarn,twist, strength, stiffness, FTIR and XRDyarn,before and afterworkinglaserwas testedand the resultsshowednosignificantchange intheseparameters But the parameters of elongation and elongation to break point in the Special Forces (EASL) and Energy in particular elongation (LASE) and shrinkage were changed. According to the results obtained from tests related to the amount of elongation to break point and elongation special forces have increased somewhat, but not outside the scope of the standard tests and special force elongation shrinkage also somewhat outside the scope of the standard is not the case in this study reduced is adhesion test (H-TEST) that matrix adhesion to rubber thread indicate estimate. Adhesion test also significantly increased the amount of this increase is to score as much as 18.3 percent in 1400 dytex Crouch and Crouch to score as much as 12.2 percent in 1880 was estimated dytex. On this basis it was determined laser act improve adhesion of the rubber thread screw. At the end of a mechanical model based on the adhesion method laser act Pull-out to determine the effect of yarn was used in tires. Keywords: yarn and tire-rubber-laser-adhesion (H-TEST)
