Cotton Fiber
Cotton is a scouring as well as bleaching were done on cotton wool it volition live an wages to throw low-cal on composition of cotton:

Cotton

Composition of cotton:

Component	Amount (dry basis)%	Main location	Primary wall (%)
Cellulose	94	Secondary wall	48
Protein	1.3	Lumen	12
Pectin substance	0.9	Primary wall	12
Oil, obese & wax	0.6	Cuticle	7
Ash	1.2		3
Malic, citric as well as other organic acids	0.8	Lumen	14
Total sugar	0.3	Primary wall
Pigment	Trace
Others	0.9

Cellulose:

Cellulose content of the raw cotton wool fiber ranges from 88 to 96 %. Cellulose is a polymer of ß-D-glucose amongst a specific configuration shown inwards figure. The cellobiose, repeating unit of measurement of cellulose, consist of 2 beta glucose molecules linked together at the 1:4 carbon atoms. Each successive glucose unit of measurement is rotated 1800 roughly the molecular axis. This gives a linear polymer chain that is close apartment thence suitable for fiber formation.

Chemical Structure of Cotton

About 5000 cellobiose units are introduce inwards cotton wool that is score of polymerization of cotton wool is 5000.

Protein:
These areas are derived from the protoplasm of living cell. Fiber contains a small-scale per centum of nitrogen but non all of the nitrogen is introduce every bit protein. It is believed that nitrogen-containing compounds may live associated amongst the natural coloring matter.

Pectic substance:
Natural cotton wool contains derivatives of pectic acid. They appear every bit mainly calcium as well as methyl pectates. But costless pectic acid as well as methyl pectate are besides present.

Oil, obese as well as wax:
Oils as well as fats are esters of glycerol (glycerides) amongst higher saturated as well as unsaturated obese acids. Waxes are esters of complex monohydric alcohol amongst obese acid.

Oils, fats as well as waxes are all insoluble inwards water, oils as well as waxes of cotton wool consists of:

1. Glycerides which are readily saponifiable oils as well as fats
2. Waxes which are saponifiable amongst difficulties
3. Unsaponifiable oils
4. Free obese acids as well as
5. Traces of soaps
