Analysis of the Impact Resistance Capacity of 3D Spacer Fabrics Based on Impact Tests

摘要

The?article presents the structure influence of distance spacer fabric on the ability to protect against impact based on impact test results of selected packages made of spacer fabrics. The?aim of testing these materials was to check their ability to suppress the impact force and absorb the energy in anti-impact vests. The?purpose of using these textile materials in protective clothing would be to reduce the weight of the final product, and thus also to reduce heat stress during use. The?article contains test results of the force received under an anvil and of the energy absorbed for each of the packages tested. The?textile package developed, consisting of three layers, was classified as a?protective material because it meets the requirements of EN 13158:2018 Protective clothing – Protective jackets, body and shoulder protectors for equestrian activities. The?package provides protection at Level 1, the force received under an anvil during tests was 1.55 kN, and the package absorbed 24.96% of all impact energy. Additionally, the selected package was tested for air permeability.
