THE TYPES OF FIBRE TO WEAVING THE TOWEL (P.1)

Origin:

Cotton is a natural, soft fibre that grows with the seeds of the cotton plant.  After the cotton fibre is gathered from the plant, it can be made into thread. The cotton thread can then be made into cloths

Feature:

Cotton yarn is a natural fibre. It can be better absorbability than synthetic fibre.

Cotton fibre can absorb up to 65% (of its own weight)

cotton can absorb up to 20% (of its own weight) of water vapour without feeling wet and up to 65% without dripping.

However, clothes that are made from cotton fibre after absorbed will be very dry slowly. In addition, cotton fibres tend to be grease, dirty but they can be washed off cleanly.

Cotton fibres is suitable for all skins ( don’t cause itching). It is really important material in the textile industry

Shape:

flat yarn, twisted.

Cotton fibers are insoluble in water, when it is wet, it will become more supple than drying.

The toughness of cotton yarn is poorer that the types of fiber from the tree bark but the stretch of cotton yarn is better

Cotton fibers is durable with the alkali but not to the acid, it can be destroyed by microorganisms.

However, ability can stand the termites and other insects is very high. Flammable cotton but can be boiled in sterile water for sterilization

Cotton fibers can stand temperature and alkali because of molecular structure

It is very durable in spite of washed several times. Cotton fibers are used extensively in chemicals, traction, abraisives or salts as in the case of fishing nets, sails for boats, clothing, work clothes, table cloth, bed linen.

Depending on the requirements of each application, raw cotton can be processed through various stages to achieve quality not less than silk without losing the outstanding advantages of the material.

Application: 

Fishing net, rope, zip are usually made from cotton yarn. In addition, tent cloth, the canvas is also made from this material.

Previously, the fire hydrant sprinklers were also made from cotton fibers. Cotton is also used to make paper, cellulose, coffee filter bags and bookcases, etc.

in Nitro-cellulose, cotton yarn is used to make ammunition and dynamite

cotton is also used as a component in synthetic materials

After pressed oil from cotton yarn is refined, it can be used for cooking oil, fuel, and raw materials in the cosmetic industry

Cotton residue can be used for animal food ( because it contains a lot of protein). However, because of its high Gossypol content, it can only be used as food for mature ruminant

Seeds of cotton can be used for processing 20% (oil), 50% (residue), remaining (husk)

In olden times, US use it to make the abortion pill

Preservation:

Cotton is very easy to wash. You can wash by washing machine

Do not wash cotton at too high temperature or too often because it can damage the fabric and damage the design

If you use bleach on coloured cotton, you have to make sure that it does not fade

Cotton is not elastic but it can be wrinkled and should be ironed carefully

Notes for cotton towels when washing:

Do not use soap with the strong detergent

Do not expose directly in the sun

Do not rub or wring too strong hand

If you iron the towel when it is moist, it becomes more flatter
