What is mercerized finish?

Table of Contents

Mercerisation is a textile finishing treatment for cellulose fabric and yarn, mainly cotton and flax, which improves dye uptake and tear strength, reduces fabric shrinkage, and imparts a silk-like luster.

What is mercerised fabric?

mercerization, in textiles, a chemical treatment applied to cotton fibres or fabrics to permanently impart a greater affinity for dyes and various chemical finishes.

How do you care for mercerized cotton?

Mercerized cottons do not require special care. ORDINARY COTTON FABRICS, unless of delicate weave and color, can stand hard laundering with hot water and almost any soap or detergent, and ironing with a hot iron. They give very little trouble.

Which chemical is used in Mercerizing finish?

Mercerization is a process in which textiles (typical- ly cotton) are treated with a caustic (NaOH) solution to improve properties such as fiber strength, shrink- age resistance, luster, and dye affinity. The caustic actually rearranges the cellulose molecules in the fiber to produce these changes.

What are the advantages of mercerization?

Mercerizing leads to an improve- ment in each of the following properties: lustre, tensile strength, absorption of dyes, coverage of dead cotton, and dimensional stability. The many benefits that arise from normal mercerizing are, nevertheless, largely surface effects, particularly on woven fabrics.

Is Egyptian cotton mercerized?

Egyptian Pearl Cotton is a 2-ply mercerized cotton yarn with a lustrous sheen and a distinctive twist. It’s easy to work with, strong and durable.

Does mercerized cotton shrink?

The process shrinks the cotton fibers, tightening and smoothing the grain of the thread. Because the cotton is preshrunk, mercerized cotton also tends not to shrink as much as regular cotton, so consumers can be more confident about the fit of mercerized garments.

What is the difference between mercerized and Unmercerized cotton?

Pearl cottons absorb dyes better and therefore show more saturated hues; mercerization also provides a sheen that tends to intensify color. Unmercerized cotton yarns are duller in color and more matte in texture. They absorb water better, however, which makes them a good choice for towels.

Why mercerizing is done?

Mercerization is one of the most important finishing processes of cotton with a strong caustic alkaline solution in order to improve the lustre, hand and other properties. It imports gloss to the fibre, increases its hygroscopicity, strength and improves its dye affinity.

What are the types of mercerization?

Types of Mercerization

i. Mercerization without tension. Mercerized cotton fibers swell without tension which increases in length and thickness.
ii. Mercerization under tension.
iii. Chainless mercerization.
iv. Chain mercerization.
v. Cold mercerization.

What is mercerisation in textiles?

What is mercerized cotton yarn?

Mercerized cotton yarn reels Spool of a two-ply mercerized cotton thread with a polyester core. Mercerisation is a textile finishing treatment for cellulose fabric and yarn, mainly cotton and flax, which improves dye uptake and tear strength, reduces fabric shrinkage, and imparts a silk -like luster.

What is the difference between dry mercerization and mercerisation?

The improved lustre of mercerised cotton is due to the production of nearly circular cotton fibres under tension. Another characteristic feature is the untwisting (deconvolution) of the cotton hair. In dry mercerization, the process is carried out while drying the fabric on a stenter.

Can tubular fabric be mercerized?

Tubular fabric can be mercerized, but this process offers no control over the technological data of the finished fabric. In addition, the consumption of caustic soda, water and steam is significantly higher than with a modern, open width mercerization system.
