Chemical properties of rayon fiber

 Chemical properties of rayon 

Reaction in acid: Cellulose acetate rayon fiber is more tolerable than viscose rayon. It can dissolve in acetic acid. In concentrated acid, this fiber can be damaged. 

Reaction to alkali: Concentrated alkali can disintegrate cellulose acetate rayon fiber. But minor concentrated alkali can not harm.

Reaction in bleach: Have good tolerability in concentrated oxidizing and reducing agents. White cellulose acetate fiber has no need for bleaching.  If need bleaching then we can use a mild solution of hydrogen peroxide or low concentrated hypochlorite bleaching.

Effect of light: This fiber has more light-preventing power than cotton and any other textile fiber. But after a long time in light, it can lose its strength. 

Resistance to mildew: cellulose acetate fiber has high resistance to mildew. It is ideal for fabrics exposed to moisture such as shower curtains. 

Effects in solvents: Dry cleaning solvent can not harm this fiber but dissolve in acetone. 

Resistance to insects: This fiber has good resistance to insects. It is never affected by moths and carpet beetles or any other natural insects. So we have no need for any kind of proofing.  

Resistance to perspiration: It has good resistance to perspiration. But if this fiber is not dyed in a solution dye then the color may change. 

Affinity for dyes: Acetate fiber is dyed with a special kind of dyes. Acetate fiber fastness is not good at atmospheric gases. The grey color and blue colors are mostly fade badly and change color to pink red and purple. An inhibitor can be used during the finishing of this fiber to minimize this type of effect.
