Global competitive pressure is the reason for ultra-short liquor ratios and extremely high speeds of circulation in discontinuous dyeing and pretreating operations which often affect fabrics mechanically, even in the age of hydro and aerodynamic dyeing machines.
Abrasion marks, running creases, pilling or so-called “crowsfeet“ and “irregular crêpe effects“ form. Depending on the quality of the substrates and the extent of the damage, repairing is time and cost-intensive or often no longer possible at all.
To counteract or prevent affected fabric qualities, the use of so-called running crease inhibitors is indispensible.
Running crease inhibitors reduce both the friction “fabric on fabric“ and between textile and the metal parts of the machine and thus contribute to better plaiting. The penetration of the running crease inhibitor into the yarn simultaneously results in more fabric “flexibility“. This is better protection from durable mechanical fabric deformation.
Apart from these desired primary effects, running crease inhibitors often confer additional properties, such as wetting, dispersing or levelling. Some running crease inhibitors impart durably increased elastic recovery, better hydrophilic properties or soft handle to fabrics.
The right product selection is, hence, paramount and should always be exactly adjusted to the respective fibre type, processing step, fabric construction, etc.
