Textile desizing process definition purposes classification

Textile desizing process definition purposes classification:

Introduction:

Sizing is the process of applying adhesive material and other ingredients to the yarn to make it shiny and smooth by mixing the various fibers in the yarn before weaving, such as strength, weight gain, abrasion resistance, and excess fibers present on the yarn surface. After weaving the cloth in this sized condition, the cotton is brought to the finishing department to finish, that is, to apply methods like scouring, bleaching, dyeing, printing, etc. But even then the above sizing material remains which causes various difficulties in the process of finishing the fabric. To overcome these difficulties, the sizing material located in the fabric has to be removed. https://bdfabric.com/labor-law-of-bangladesh/

The process by which sizing components remove like starch is called desizing. Other sizing components such as wax, fat, etc. are removed in the next scouring method. The desizing method is the earliest chemical method of wet processing. https://bdfabric.com/procedures-for-resolving-industrial-disputes/

Textile desizing process definition purposes classification-Definition of desizing:

Weaving is the process by which the water-absorbing capacity of fabric is increased by removing starch from the fabric obtained from the loom is called desizing.

Textile desizing process definition purposes classification-Purposes of desizing:

1. Removing starch from woven cloth.

2. To increase the water absorption capacity of cloth.

3. Increasing the absorption capacity of the fabric against the chemicals used in the next process.

4. Prepare the fabric for the next process.

5. Assist in enhancing the luster of the fabric in the dyeing and printing process.
