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.
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. The weaver painted the size onto the warp as it lay on the loom, then fanned it dry before weaving the cloth. The ...
Polyvinyl alcohol (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer.It has the idealized formula [CH 2 CH(OH)] n.It is used in papermaking, textile warp sizing, as a thickener and emulsion stabilizer in polyvinyl acetate (PVAc) adhesive formulations, in a variety of coatings, and 3D printing.
Textile testing is the process of measuring the properties and performance of textile materials—textile testing includes physical and chemical testing of raw materials to finished products. Textile testing assists textile production in selecting various types of fibers and their transformation into yarn , fabric, and finished goods such as ...

Methyl cellulose is used as sizing in the production of papers and textiles as it protects the fibers from absorbing water or oil. When applied to several pieces of paper, methyl cellulose will bind the layers together, often to create a more durable or multicolored sheet.
Chemical finishing refers to the process of applying and treating textiles with a variety of chemicals in order to achieve desired functional properties. Chemical finishing of textiles is a part of the textile finishing process where the emphasis is on chemical substances instead of mechanical finishing.
