No. Viscose is a man-made fibre, made from regenerated wool cellulose.
Wool is fabricated from animal fleece.
wool viscose
YES
viscose dissolve in 40% sulphuric acid,but cotton in 70%.
how to differenciate poly cotton and poly viscose
Obviously 100% viscose is made wholly of viscose - while 50/50 is a mix of equal proportions of cotton and viscose !
No it is not.
Viscose rayon is a man-made fiber made from wood pulp though other materials may be used. It is basically modified cellulose. Viscose is very similar to cotton and silk. (Cotton is also made of cellulose). Viscose falls somewhere in between a natural fiber and a man-made one. The raw material for viscose is cellulose which is usually reacted with caustic soda and carbon disulfide. It is reformed as fibers by spinning this viscose solution in an acid bath. Viscose rayon has a silky appearance and feel, and also has the ability to breathe in a manner similar to cotton weaves.
Cotton Viscose
If you had a length of cotton yarn and a length of viscose (or rayon, is another word for viscose), yarn and you were attempting to differentiate between the two, it is tricky. I would suggest that you wet both strands of yarn, and pull them. The rayon will stretch more and be less strong than the cotton. The rayon will also absorb more water than the cotton yarn.
viscose has 67 % amorphous region & 33% crystalline reason exactly reverse of cotton ,so viscose absorb more moisture than cotton as well as due to hydrogen bonding (formation of hydrogen bonds means addition of bonds) wet strength of cotton increases but in case of viscose no of hydyogen bonding breaks are much more(means break up of hydrogen bonds are much more than addition) so wet strength decreases.
due to hydrogen bonding no of molecular rearrangement in the structure is more than viscoce in viscose hydrogen bonds break up is more in terms of molecular arrangement so wet strength of cotton is higher than viscose fibre rajarahul28@gmail.com
Viscose fabric breathes much the same way cotton fabric does. It would be good to wear in hot weather as it is good for dispelling heat from he body.
viscose is mixture of cotton and other fibres , i was manfacture simply way to shrink viscose to use heavy hot steam making sure not to touch matarial keeping the iron 12 inchs away, best result industrial steam , sure result,
