What is finishing process in textile:

Introduction:

Textile finishing refers to the combination of all activities that make it suitable for marketing textile products. Usually, the cloth is also marketed as a bleached finished product. Again in most cases, the fabric is finished after dyeing and printing. The finishing process usually depends on the type of fabric market demand. In addition, the main purpose of finishing is to enhance the beauty of the fabric and make it usable. https://bdfabric.com/discharge-style-printing-by-vat-dye/

Finishing in the broadest sense is all of the mechanical and chemical processes that are carried out in stages after the gray cloth is removed from the loom. That is to say, after preparing the gray cloth from the loom or after dyeing and printing the cloth, the luster, softness, appearance, and all the methods to make the buyer attractive to the general public i.e. the combination of mechanical and chemical methods is called finishing.

The use of fabric finishing methods results in water, fire, moth, and mildew proofing in some cases, including the acquisition of flexible, soft, shiny, flawless, non-shrinkage, strong, size recovery, etc. The fabric finishing process largely depends on the texture of the fabric and what it will be used for.

The finishing process usually depends on the following factors.

1. On the type of fabric, chemical condition, and structure.

2. Physical properties such as flexibility or elasticity, on the degree of length increase, the degree of friction, and the conductivity.

3. Field of use of cloth.

4. Whether it is suitable for special types of finishing such as fire retardant, water retardant, etc.

5. Whether any reaction occurs in chemical treatment.

Objects of finishing:

The fabric is usually finished for the following purposes.

1. Make the clothes attractive.

2. To enhance the luster and beauty of the fabric.

3. To make the cloth suitable for folding, dirt, shrinkage, i.e. improved wear.

4. The fabric to make it soft, supple, and smooth.

5. To remove the hairiness and roughness of the clothes.

6. Arranging the fabric and bringing it to the required shape (dimension).

7. Apply waterproof, fireproofing, mothproofing, and soft finishing methods to the fabric.

8. Increase the abrasion resistance of the fabric.

9. Especially to increase the weight of the fabric.

10. Covering the shortcomings of the cloth.

Classification of finishing process:

The finishing process can be roughly divided into two parts. E.g.

1. Mechanical finishing process

2. Chemical finishing process

1. Mechanical finishing process:

What is the finishing process in textile? Finishing methods that are done mechanically, that is, with the help of machines, no chemicals are used are called mechanical finishing methods. For example, starting from drawing with the help of steaming, means calendaring, stenting, softening, sniffing, sanitizing, etc. Such finishing is done by steam, heat cylinder, or stenter. With the help of stenter the width and shape of the cloth are restored.

2. Chemical finishing process:

Chemical finishing methods are the finishing work that is done by applying chemical elements or products in the fabric or by causing a chemical reaction, such as bleaching, mercerizing, softening, wetting, etc. moth Proofing, waterproofing, fireproofing, etc.

Again, finishing can be divided into two types based on the results of finishing. E.g.

(A) Temporary process

(B) Permanent process

(A) Temporary process:

Mechanical: calendaring, embossing, beating, etc.

Chemical: filling, softening, etc.

Usually, temporary mechanical finishing is more. Temporary chemical finishing is less.

(B) Permanent process:

Mechanical: Milling, Rising, Sunforisng, etc.

Chemical: Bleaching, Mercerizing Anti creasing, Water Proofing, Fire Proofing, etc.

Some special types of chemicals are used in chemical finishing, which are called finishing chemicals. The use of chemicals in the fabric usually depends on the type of fabric, the demand of the buyer, and the mechanical condition applied to the fabric.
