What is sizing process in textile?
Sizing is the process of giving a protective coating on the warp yarn to minimize yarn breakage during weaving. Sizing is the most important operation in preparing warp yarn for weaving especially with cotton yarn.
What are the different types of sizing?
Sizing process is classified into three types, which are pointed out in the below:
- Pure sizing,
- Light sizing,
- Medium sizing,
- Heavy sizing.
Why sizing is required for weaving process?
The main objective of the sizing process is given below: To improve the weavability of warp yarn. To improve the fibre to fibre adhesion force in the yarn. To prevent slippage of fibres in the yarn during weaving.
How sizing is done?
Sizing is done by applying various types of size materials on the yarn. During application of size materials steam is needed. Sizing is a protective process. The process of applying a protective adhesive coating upon the yarns surface is called sizing.
What is sizing and desizing?
DESIZING I • Desizing is the process of removing the size material from the warp yarns in woven fabrics. • Sizing agents are selected on the basis of type of fabric, environmental friendliness, ease of removal, cost considerations, effluent treatment, etc.
What is sizing and its objectives?
The main objective of sizing process are given below: To improve the weave ability of warp yarn. To improve the fibre to fibre adhesion force in the yarn. “To make the yarn twist permanent by applying adhesive film on the yarn surface.
What are the sizing ingredients?
The materials which are used for sizing that is called size ingredients. A gelatinous film forming substance in solution or dispersion applied normally used for warp yarn but sometimes used for weft yarn before weaving is called size.
What is the purpose of sizing?
Sizing is used during paper manufacture to reduce the paper’s tendency when dry to absorb liquid, with the goal of allowing inks and paints to remain on the surface of the paper and to dry there, rather than be absorbed into the paper.
What is the function of sizing?
What are the requirements of sizing ingredients?
Choice of size ingredients are given below:
- The recipe should give the fewest breakage during weaving.
- It should give least amount of exfoliation.
- It should permit easy size removal in later operation.
- It should give good fabric characteristics.
- The recipe should be compatible with the machinery.
What is sizing and desizing in textile?
• Desizing is the process of removing the size material from the warp yarns in woven fabrics. • Sizing agents are selected on the basis of type of fabric, environmental friendliness, ease of removal, cost considerations, effluent treatment, etc.
What is CBR in textile?

What are the applications of textile fabric?
The textile fabrics have a wide range of application in areas like apparels, home textiles and technical textiles. The manufacture of a cost effective quality product requires the careful planning and thorough knowledge of the production process.
What are the latest developments in textile machinery?
The latest developments and automation in the textile machinery has resulted in a more efficient production cycle. Unfortunately, the published work available on the topic of woven fabric calculations is quite out dated, while no significant work has been reported on the calculations of knitted fabrics.
How to manufacture a cost effective quality fabric?
The manufacture of a cost effective quality product requires the careful planning and thorough knowledge of the production process. This objective cannot be achieved without the know-how of the calculations involved in the fabric formation process.
What are the principle sizing factors influencing weaving efficiency?
