Finishing is the process used to enhance the look and feel of the fabric. Finishes can be achieved both physical and chemical change.In this article we will discuss about Finishes achieved by physical change.
Physical means of Finishing
It is a mechanical process in which the fabric is passed between heavy rollers, combining heat and pressure. Finishes like glaze, watermark or moiré can be achieved. Calendering is mainly done on synthetics because it is not permanent on fabrics made of natural fibres.
2. Heat setting
A final finishing that heats thermoplastic manmade fabrics to just below their melting point. Thermoplastic nature fabrics change with incerese of heat and come back to its form at normal temperature. In heat setting treatment it stabilizes the fabric so that there will be no further change in its size or shape and therefore improves the fabrics’ resilience.
Fabric surfaces are raised and plucked with needles on roating drums to create a woolly or flannel surface
Fabrics are usually sheared to give the surface a uniform pile.
4. Sanding or sueding
In this process the the fabric is rubbed with rollers coated with fine- grit
sandpaper to create a soft surface.
5. Shrink control
The preshrinking of cotton cloth so that it will not shrink during laundering. This process is also know as Sanforizing or compacting.
