EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of DIN 53924 testing. This standard specifies a test method for determining the rate at which textile fabrics absorb water from textiles, yarns and rovings with good absorbency. This document does not apply to towels and similar products for drying or dressing items.
Modification of the surface energy of textile fibers is done in order to improve their hydrophilicity, wettability and dyeability or to provide functional properties such as hydro and oil repellency, dirt release, adhesion improvement and antistatic performances. If the modification is limited to a thin surface layer of fibers, the bulk properties of a textile such as mechanical strength, flexibility, breathability and softness must not be compromised.
Surface modification of textile fibers can be accomplished by physical or chemical methods or a combination of both. Plasma processes and radiation exposure represent mainly physical methods, although their effects are usually carried out in the presence of reactive gases or after impregnation with suitable chemicals. However, chemical treatments can often be carried out with oxidants or other finishing agents followed by heat treatment.
There are many differences between textile fibers in terms of wettability and surface structure. Natural fibers have more complex cellular structures than synthetic fibers obtained by chemical spinning. Wool and fine animal fibers are mainly composed of keratin, but show the structure of the composite material formed by the assembly of cuticle cells in the form of scales and cortical cells surrounded by a keratin cell membrane and held together by an intercellular cement.
