Obviously 100% viscose is made wholly of viscose - while 50/50 is a mix of equal proportions of cotton and viscose !
Yes, often times it is, but you need to check the label. Sometimes it's a cotton polyester blend.
No. A 100 % cotton shirt will not shrink when you wash it.
England XD Odyssey Ware!
300 washes if the water quality and temperature is monitored as well as good quality agents are used.
how to differenciate poly cotton and poly viscose
viscose dissolve in 40% sulphuric acid,but cotton in 70%.
Combed cotton is softer and finer than ordinary cotton. Impurities in combed cotton were brushed out after the initial spinning.
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.
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.
No it is not.
No. Viscose is a man-made fibre, made from regenerated wool cellulose. Wool is fabricated from animal fleece.
Nothing. Companies like to add the term "organic" to products so they can charge more and get away with it.
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 firstname.lastname@example.org
