Sizing the warp. Textile warp sizing, also known as tape sizing, of warp yarn is essential to reduce breakage of the yarn and thus production stops on the weaving machine. On the weaving machine, the warp yarns are subjected to several types of actions i.e. cyclic strain, flexing, abrasion at various loom parts, and inter yarn friction.
Enzymatic desizing is the classical desizing process of degrading starch size on cotton fabrics using enzymes. Enzymes are complex organic, soluble bio-catalysts, formed by living organisms, that catalyze chemical reaction in biological processes. Enzymes are quite specific in their action on a particular substance.
The size stiffens the thread and helps the fibres lie closely together. [2] Many recipes for size can be found in textile manufacturing books. The recipes include flour, sago, china clay, types of soap, fats and some chemicals. [2] [3] Before mechanisation, the sizing process was a time-consuming task.
