The influence of polyamide fibres and knitted fabric structures on thermophysiological properties

Abstract

This study aims to analyse the influence of distinguished polyamide fibres knitted in different ways to improve the thermal physiological properties of fabrics used in clothing for bedridden patients. To this end, four distinct fibre compositions were, each one, knitted into four different structures, and this plan generated 16 samples. Structural characterization of the samples, permeability analyses, and Moisture Management tests were carried out. Was possible to conclude that some parameters such as filament dimension, fabric loop length, and how the yarns are knitted, have a direct influence on the thermal behaviour of knitted fabrics. The sample made of PA fibre 44/40 in a jersey fabric, presented the best results, due to its reduced thickness, superior loop length, and the use of a 40 multifilament.
