What is mercerised yarn?
Mercerization is a process that makes the yarn smooth, stronger and takes dye better. John Mercer, and English textile chemist, developed the technique in 1844 to improve the dye qualities of cotton yarn. Towels made of mercerized yarns retain their beauty longer than those made from unmercerized yarns.
Is Mercerised cotton expensive?
Mercerization is therefore an expensive chemical procedure. However, this finishing process has numerous benefits. The changed structure gives the cotton a silky, wash-resistant shine. Color fastness is significantly increased and the yarn is left stronger.
Is all cotton yarn mercerized?
Mercerized cotton is a special kind of cotton yarn that is more lustrous than conventional cotton. Mercerization, the process by which mercerized yarn is made, is named for the British chemist John Mercer, who developed the process and received a patent for his work in 1851.
What is gassed yarn?
Gassed yarn is mercerized cotton yarn that has been exposed very rapidly to a hot gas flame. This process removes any fuzz or excess lint on the thread. This results in a brighter and smoother appearance.
Why Mercerizing is done?
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.
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.
Is Mercerised cotton safe?
Mercerized fibers have undergone a nontoxic process by which they have been immersed under tension in a strong solution of lye, which is then washed off. This permanently improves the strength, absorbency, and appearance of the fabric, and provides excellent colorfastness.
What is double mercerized cotton?
Fabrics, too, can be mercerized after they’re woven. A fabric woven from mercerized yarns, which is then mercerized, is called double-mercerized. I’m not sure that all mercerized fabrics are labeled thus, but if a textile is, you can expect it to be silky in texture and rich in color.
What is double gassed cotton?
Double gassing is the process of burning off the lint! The first pass will burn off 80% of the surface lint, resulting in an already much cleaner, much lower lint look. We send our threads through for a second run, burning off an additional 80% of the remaining thread.
Which chemical is used in Mercerizing process?
sodium hydroxide (NaOH)
The alkaline treatment or mercerization is a chemical treatment in which the natural fibers are immersed in a known concentration of aqueous sodium hydroxide (NaOH) for a given temperature and a period of time.
