Requirements Of Sizing | Choice Of Size Ingredients

Sizing

Sizing is important for weaving but if the process does not do with proper accuracy then everything will be hampered. For this reason, a textile engineer should be very careful during sizing operations. Sizing applies for grey or striped fabric production. In denim; sizing is done after the scouring, bleaching, and dyeing process.

Requirements of Sizing

A sizing process should fulfill the following requirements, which are important for fabric production. They are-

• Firstly, sized warp must be sufficiently strong, smooth and elastic.
• Secondly, the sizing process must ensure the application of the required amount of size on the yarn or the required size regain.
• Thirdly, the tension of warp yarn at sizing must be regular and constant all the time of warp unwinding from warp beam.
• After taht, yarn strength and loss in elongation should be admitted limits.
• Then, the package, i.e. the weavers beam produced must have cylindrical shape, necessary winding density and yarn strength.
• Lastly, the sizing process must be efficient, economical and must ensure the production of high quality sized warp.

Choice of Size Ingredients

Different size ingredients have different characteristics. The following is the factor of choice size ingredients. They are-

• Firstly, the recipe should give the fewest breakage during weaving.
• Secondly, it should give least amount of exfoliation.
• Thirdly, size ingredients should permit easy size removal in later operation.
• Therefore, it should give good fabric characteristics.
• The recipe should be compatible with the machinery.
• After that, size ingredients recipe should not cause any health hazard.
• Then, the recipe should not cause any degradation of textile materials.
• It should be cheap but not necessarily.
• Lastly, P^H should lie between 7 to 7.4.

In sum, size ingredients have a great influence on the sized yarn preparation. So, one should use the best quality size ingredients.

Finally, that’s all about the requirements of sizing and choice of size ingredients.
