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:

Below are the key advantages of warp yarn sizing prior to weaving.

To bind the yarn by adhering the fibers together and hence improve yarn strength.
To cover outer yarn surface for improving abrasion resistance of the warp yarn.
To lubricate the yarn surface for reducing friction during weaving process by preventing inter yarn entanglement and surface abrasion. This reduction of friction helps to keep the yarn intact and hence better fabric quality.
Sizing Process in nutshell:

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.
Next the yarn sheet is passed over the after waxing roller to coat the sizing chemical film with extra lubricants for hairiness control and ease of weaving.
After drying and after waxing, the warp sheet is split so that the yarns regain their individual identity before they are wound on the weaver’s beam.
Splitting is required because warp sheet coming out of the drying section adhere to each other depending on the efficiency of the pre-drying section. Chromium coated Lease rods split the warp sheet in a systematic manner so that the yarns which are stuck together by dried size are separated.
After the splitting, the warp sheet is finally wound on the weaver’s beam. The warp sheet passes through an adjustable reed which can be expanded or collapsed based on the width of the beam.
Zydex had been pioneer in field of textile sizing. We have a wide range of products for sizing of spun yarn as well as filament yarns.

Zydex had been at the forefront of innovation for polyester sizing products. Today, Zydex has the leadership position in hot water dispersible polyester resin technology for sizing and weaving of polyester multi filament yarn on high speed weaving machines. This polyester based sizing chemicals have been engineered to exactly replace acrylic size and work at lower SPU but more importantly use the same desizing recipe with caustic and soap for desizing with excellent results. Our products form nano-level dispersion that results in outstanding filament-to-filament bonding.

The technique of sizing a warp was mechanised during the nineteenth century when William Radcliffe and his assistant Thomas Johnson invented the sizing machine. The purpose of introducing size, which is either a starchy substance for cotton or gelatinous mixture for woollen fibre, is to reduce the chances of threads fraying and breaking due to the friction of the weaving process.[1] 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]
An example of a sizing machine made in 1919 by Howard and Bullough Ltd, Accrington, Lancashire, England, can be seen in the tape size room of Queen Street Mill Textile Museum, Burnley in Lancashire.[4] Other early twentieth century sizing machine manufacturers were Brook and Crowther, T., Ltd of Huddersfield, Butterworth and Dickinson Ltd, Burnley and Platt Bros & Co. Ltd.[3]
