Study on woven finishing methods

in woven dyeing industries1 Introduction:

Finishing: Finishing is the general term for a multitude of

processes and treatments that a fabric may undergo after it has

been made (woven or knitted) and colored (dyed or printed). It is

the final processing of cloth.

Woven fabric: Weaving is the process of interlacement of two

sets of yarn to make a fabric. The threads which run lengthways

are called the warp and the threads which run across from side to

side are the weft or filling. Cloth is usually woven on a loom, a

device that holds the warp threads in place while filling threads

are woven through them. By this process which fabric is produced

is called woven fabric.

Relation between woven fabric and finishing: In Bangladesh

woven fabric is used widely. The finishing line after dyeing of

woven fabrics is easier than knit fabrics. Most fabrics will have

been subject to finishing treatment before being offered for sale.

Some fabrics may have two or more finishing treatments to make

them suitable for their intended end use.

2 Objective of Woven fabric finishing

Different finishes are done for different purposes. Mainly the

purposes of finishing are:

To improve the appearance of the fabrics

To fulfill the buyer requirement

To make the fabric more suitable for its intended end use

To give desire effect on the fabric

To improve aesthetic properties

To improve functional properties

3 Types of Woven fabric finishing

Most fabrics produced by weaving or knitting have to undergo

further processing before they are ready for sale. In finishing, the

fabric is subjected to mechanical and chemical treatment in which

its quality and appearance are improved and its commercial value

enhanced. Each type of fabric has its own particular finishing

operations.

3.1 Mechanical finishing

3.2 Chemical finishing

The finishing activities in different types of textile

manufacturing require a comprehensive range of chemicals which

are used for textile finishing purpose. Chemical finishes of textile

products primarily deals with the wide range of effects that

directly results from the action and reaction between the

chemicals and the textile finishing products.

Finishing, as the term implies, is the final step in fabric production. Hundreds of finishes can be applied to

textiles, and the methods of application are as varied as the finishes.

Cotton fabrics are probably finished in more different ways than any other type of fabrics. Some finishes change

the look and feel of the cotton fabric, while others add special characteristics such as durable press, water

repellency, flame resistance, shrinkage control and others. Several different finishes may be applied to a single

fabric.
