What is Sizing?
Production of ‘quality’ fabric economically and efficiently is key aim of any textile company. Sizing is an intermediate protective process which is done to prepare the yarn for the weaving process. The process of applying a protective adhesive (synthetic/ natural) coating upon the yarns surface is called sizing. This adhesive can be single shot sizing chemical or a blend of multiple chemicals to achieve desired properties.
Advantages of Warp Yarn Sizing in Weaving:
Yarn Sizing is carried out by passing the warp yarn sheet through size box containing the pre-prepared sizing chemical. The warp sheet is passed through tension roller, immersion roller, sizing roller and squeezing roller respectively in sow box. This is followed by subjecting the yarn sheet to drying cylinders heated through steam where the water is evaporated from yarn surface and sizing chemical forms a film on same.
