Identifying Fibres Viscose Rayon

(info on Viscose Rayon Velvet is at the bottom of this article, if you have Acrylic VELVET Pile fabrics click link please, also check out Identifying Fabrics and The Hypersensitivity Test ) The Rayon fibre is composed of pure cellulose. the substance of which the cell walls of such woody plants as trees and cotton are largely comprised. We are already familiar with cellulose in the form of products like paper. Rayon fibres are made from cellulose that has been reformed or regenerated. Consequently these fibres are identified as regenerated cellulosic fibres. Viscose rayon, for example, is made from cotton or wood pulp usually obtained from spruce, hemlock and pine trees. The Production of rayons as a regenerated cellulosic fibre originated the synthetic fibres. The One great advantage of the introduction of this fibre was the continuous yarns which were produced. There are many different trade names used in the connection with rayons but some of the most important facts to know about rayons are as follows.


Viscose is about half as strong as silk. it is also weaker than cotton and linen but stronger than wool, yet although rayon is weaker than most natural fibres, it produces fairly durable, economical and serviceable fabrics whose smoothness of surface favourably withstands the friction of wear.


Viscose rayon has greater elasticity than cotton or linen but less than wool or silk. therefore, while viscose rayon fabrics have some inherent extensibility, undue strain might cause them to sag and even burst.


Viscose rayon is one of the most absorbent of all textiles. it is more absorbent than cotton or linen and is exceeded only by wool and silk in absorbency. One limitation in this regard, however, is that rayon loses up to 70% of its strength while its wet and can not take much strain when wet. also rayon absorbs moisture from the air. there is a tendency to sag. but as humidity reduces, the fabric shortens. This presents a disadvantage for its utilisation in curtains.

Cleanliness Ans Washability

The smoothness of viscose rayon fibres helps to produce hygienic fabrics that shed dirt. some viscose rayon wash easily and depending on the finish that may be given to them they will not become yellow when washed of dry cleaned. When in doubt about rayon fabrics washing it is safer to dry clean because viscose dry cleans very well.


Viscose Rayon fabrics tend to shrink more than cotton fabrics of similar construction.

Effect Of Light

Viscose rayon has generally good resistance to sunlight. The dyes will however fade.

Decorative Effects

Viscose rayon is often combined with other textiles fibres to produce ans decorative effect. Viscose rayon can be given a moire finish. But it is not permanent and will come out with washing or dry cleaning.

A velvet fabric constructed with viscose rayon fibres is highly sensitive to water and in most severe distortion will take place. immediately upon wetting. The distortion effect may take one or several forms. You should only dry clean this fabric finish. its possible to have your sofa cleaned on site with a machine that’s not unlike a wet clean extraction but has been build for solvent use. it will be expensive because the cleaner is using solvents (this could be £100 just for the solvents) and they have to invest in equipment that does not get used much. I do know cleaners that will hand clean dry clean only fabrics, but this is dependant on how badly soiled they are.
