We sometimes buy bedding products, and we will see some pure cotton fabrics with silk sheen. The shopping guide and we introduced that it is mercerized cotton, but we will inevitably doubt because the impression made of pure cotton gives us no silk, so today I It is necessary to talk to everyone: What is mercerized cotton.

The mercerized cotton is the best in cotton. The fabric is made of cotton as the raw material. The worsted yarn is made of high-weaving yarn. Then, special processing steps such as singeing and mercerizing are performed to make the silk yarns of high quality that are smooth, bright and soft. The high-quality knitted fabrics made from this raw material not only completely retain the excellent natural characteristics of the raw cotton, but also have the general luster of silk and the fabrics are soft to the touch.

After the mercerized cotton fiber, its fiber morphology has undergone a physical change, the longitudinal natural turns disappeared, the fiber cross-section expanded, the diameter increased, and the cross section was approximately circular, which increased the regular reflection of light, making the surface of cotton fiber products The yarn is generally bright and shiny; because the molecules are arranged closely, the strength is higher than that of the matt yarn, which increases the strength of the cotton fiber and the adsorption ability of the dye. However, the change of the cross-section and longitudinal morphological characteristics of cotton fiber is related to the degree of mercerization (mercerism). At the same time, because of the change in morphological characteristics, attention should be paid to its morphological characteristics in fiber identification.

Mercerized cotton has the following characteristics:

The fabric has a silky sheen;

Washing dimensions are stable, higher than ordinary cotton;

Fabrics are not easy to pill;

The hanging feeling of the fabric is better.

How is mercerized cotton made?

Pure cotton is treated with concentrated caustic soda and tension is applied, which is the mercerizing process. Mercerized yarn is divided into mercerized yarn, fabric mercerized, and yarn fabric is more than mercerized.

The disadvantages of mercerized cotton are:

(1) Lack of elasticity and rigidity, and it tends to wrinkle.

(2) The color fastness is not high and it is easy to fade.

(3) poor clothes shape retention, easy to shrink after washing and shape (shrink rate in the 4% -12% or so).

(4) Especially afraid of acid, such as vinegar, if you accidentally get clothes, you should wash it in time.

How to clean the mercerized cotton?

Use neutral detergent to wash;

After washing, it cannot be twisted, sun-dried, and naturally hung to dry;

The water temperature during daily washing should not be too high, keep below 40 degrees;

Avoid contact with articles such as pesticides;

Hygroscopicity, keep ventilation after washing.
