	abstract = {Vibrations can affect the human body during everyday activities or in the workplace through various tools. It can occur
at any point that comes into contact with a vibrating surface, including the hands (hand-arm vibration, HAV), the feet
(foot-transmitted vibration, FTV) or the buttocks and back (whole-body vibration, WBV). The paper presents a group of
knitted fabrics that could be used as linings for footwear or gloves, designed for personal protective equipment (PPE) in
vibration environments. These fabrics have a single jersey tubular structure and were produced on a circular knitting
machine with a small diameter and three stitch depths, made from functional yarns with good comfort properties. The
knitted materials were tested using the free vibration method to measure their natural frequencies (Hz), as knowing
these values helps to avoid resonance phenomena between the materials and the external vibrating system. The natural
frequencies were measured in three directions (course, wale, perpendicular) and the results show that, for all variants,
the natural frequencies measured in the perpendicular direction are four times higher than in the other two test
directions. The fabrics made from Outlast natural fibre yarns have 30\% lower natural frequency values than those made
from synthetic yarns (Coolpass, Coolmax) or from natural-synthetic blended yarns (Dri-Release), which confirms the
influence of the yarn type on the vibration behaviour of the materials. Coolpass, Coolmax and Dri-Release knits have
comparable values of the natural frequencies, both in the course and wale test direction (41–48) Hz and (182–189) Hz
in the perpendicular test direction. This type of knitted fabric, with low thickness and good extensibility, is suitable for
anti-vibration equipment, e.g. in the field of dentistry, where it should be combined with a suitable antimicrobial and
antibacterial treatment and a high level of comfort.},
