SUMMARY:

The objective of this work is to study the technical properties of the protective footwear used by the Federal Highway Police and compare the results with the values determined in the NRPRF-019.2015 standard, which brings the minimum conditions required for making the protective footwear. For the Federal Highway Police, this study will serve as a basis for improving their protective footwear, since in 2015, an investment was made to make a new uniform, including operational footwear. This study was carried out using two shoes with 15 days of use in order to compare with other new shoes, without use. It was observed that the footwear with little time of use had presented deformities in its structure, such as fraying of the seam in the points that suffer great tensions, especially in the region of the pipe where the mooring hooks are found, as well as between the seam of the external part with the inner part of the pipe. In view of these results, the sewing margin and the type of sewing stitch used in that region were analyzed. The seam margin was measured using a millimeter ruler, while the type of stitch was observed with the naked eye, in order to verify if it would be a tension-resistant stitch. Color variation tests were carried out using a reflectance spectrophotometer in the regions of the barrel, tongue shoe, and collar, as well as hydrophobicity tests in 07 sections of the new footwear. The results obtained showed that in relation to the seam margin, since it is a polyester fabric, it should be at least 1.5 cm from the edge; in the color variation test, he observed that there was color variation in the collar and the barrel part, both located at the back of the shoe, indicating that he was motivated by being a region more exposed to light, on the other hand, the results of the hydrophobicity showed that the external parts meet the standard perfectly.
