Comparison Table of Different Textile Fiber:
Fiber is a unit of matter, either cellulosic or synthetic or regenerated, that forms the basic element of fabrics and other textile structures. A fiber is characterized by having a length at least 100 times its diameter or width. The term refers to units that can be spun into a yarn or made into a fabric by various methods including weaving, knitting, braiding, felting, and twisting. The essential requirements for fibers to be spun into yarn include a length of at least 5 millimeters, flexibility, cohesiveness, and sufficient strength. Other important properties include elasticity, fineness, uniformity, durability, and luster.

In this article I will compare different fibers properties in case of moisture regain, effects of sunlight, effects of organic solvents, effects of alkalies, effect of acids etc.

Moisture Regain of Fibers :


Fiber
Moisture Regain (%)
7-11
11
Wool
17
Viscose Rayon
13
Acetate fibre
6.5
Nylon6, 6.6
4
1-2
Polyester(PET) fibre
0.4

Sunlight on Common Textile Fibers:

Fiber
Effects of Sunlight
Acrylic
Some little effect or no effect.
Modacrylic
Highly resistant, some loss of strength and discoloration after constant exposure.
Some loss of strength, no discoloration, very resistant behind glass.
Rayon
Generally resistant, loss of strength after long exposure.
Acetate
Generally resistant, loss of strength after long exposure.
Triacetate
Resistant, loss of strength after long exposure.
Nylon 66
No discoloration, strength loss after long exposure.
No effect.
Cotton
Strength loss on long exposure.
Wool
Strength loss, dyeing is affected.

Effects of Organic Solvents on Common textile Fibers:

Fiber
Effects of Organic Solvents
Acrylic
Unaffected.
Modacrylic
Soluble in warm acetone, otherwise unaffected.
Polyester
Soluble in some phenolic compounds, otherwise unaffected.
Unaffected.
Acetate
Soluble in acetone, dissolved or swollen by many others.
Triacetate
Soluble in acetone, chloroform and swollen by others.
Nylon 66
Generally unaffected, soluble in some phenolic compounds.
Glass
Unaffected.
Cotton
Resistant.
Wool
Generally resistant.

Effects of Alkalies on Common Textile Fibers:

Fiber
Effects of Alkalies
Acrylic
Destroyed by strong alkalies at a boil, resists weak alkalies.
Modacrylic
Resistant to alkalies.
Polyester
Resistant to cold alkalies, slowly decomposed at a boil by strong alkalies.
Rayon
No effect by cold, weak alkalies swells and loses strength in concentrated alkalies.
Acetate
Saponified, little effect from cold weak alkalies.
Triacetate
Not effected up to pH 9.8,205ยบ F; better than acetate.
Nylon 66
Little or no effect.
Glass
Attacked by hot weak alkalies and concentrated alkalies.
Cotton
Swells when treated with caustic soda but is not damaged.
Wool
Attacked by weak alkalies, destroyed by strong alkalies.
 
Effects of Acids on Common Fibers:

 
Fiber
Effects of Acids
Acrylic
Resistant to most acids.
Modacrylic
Resistant to most acids.
Polyester
Resistant to most mineral acids disintegrated by 96% sulphuric acid.
Rayon
Disintegrates in hot dilute and cold concentrated acids.
Acetate
Soluble in acetic acid, decomposed by strong acids.
Triacetate
Soluble in acetic acid, decomposed by strong acids.
Nylon 66
Decomposed by strong mineral acids, resistant to weak acids
Glass
Resists most acids. Etched by hydrofluoric acid and hot phosphoric acid
Cotton
Disintegrates in hot dilute and cold concentrated acids.
Wool
Destroyed by hot sulphuric, otherwise unaffected by acids.
