Marketing Cultivating and harvesting[ edit ] Cotton is grown anywhere with long, hot dry summers with plenty of sunshine and low humidity. Indian cotton, gossypium arboreum, is finer but the staple is only suitable for hand processing. American cotton, gossypium hirsutum, produces the longer staple needed for machine production.
Manufacturing, transport, sales and retail Step 1 Fibre production All textiles are made up of fibres that are arranged in different ways to create the desired strength, durability, appearance and texture.
The fibres can be of countless origins, but can be grouped into four main categories. Natural fibres, with the exception of silk, have a relatively short fibre length, measured in centimetres.
Silk and man-made fibres have on the other hand very long fibre lengths filaments ranging from hundreds of metres to kilometres long. Plant fibres consists of cellulosic material, normally derived from cotton, linen, hemp or bamboo, but more or less any plant with extractable cellulose can be used.
Cotton is by far the most commonly used plant fibre and the cultivation of cotton is enormously resource-intensive, with high inputs of water, pesticides, insecticides and fertilisers leaving a large toxic footprint where grown, if not cultivated organically or under specific sustainable conditions.
Wool and silk are the most commonly used fibres from this group, but the wool can come from a number of different animals. In order to make animals grow faster and produce higher yields of wool, pesticides and insecticides are used to prevent disease.
Dipping is a common practice to control parasites in sheep farming, making use of both organic phosphates as well as synthetic pyrethroid. After the wool fibres have been sheared they are treated with chemicals during the scouring and washing process.
They are heavily treated with chemicals before the new fibre is spun. The whole process of producing fibres from wood pulp is very resource-intensive, involving the use of several hazardous substances. Given all the possible monomers that can be made from a synthetic feedstock, the possible combinations are endless.
However the most common synthetic fibre is polyester, followed by polyamide, polyacrylic and aramide. Depending on the monomer used to produce the fibre, an endless number of chemicals may be used in the process. For some of the synthetic fibres such as polyester, dyeing can be accomplished already when the fibre is manufactured.
It is easy to believe that this step, which is a mechanical one, uses no chemicals. But in order to increase the strength of the fibre, increase fibre cohesion and reduce friction during the spinning process, spinning oils are added. Fabrics can be created in many different ways, the most common being weaving, knitting or through production of non-woven fabrics.
To prevent the yarn from breaking during these processes, it is important to strengthen the yarn and reduce friction. Sizing chemicals and lubricants are therefore added.The core of textile manufacture is fabric production. Fabrics can be created in many different ways, the most common being weaving, knitting or through production of non-woven fabrics.
To prevent the yarn from breaking during these processes, it is important to strengthen the yarn and reduce friction. Textile manufacturing is a major industry. It is based on the conversion of fiber into yarn, yarn into fabric.
These are then dyed or printed, fabricated into clothes. Different types of fibers are used to produce yarn. Cotton remains the most important natural fiber, so is treated in depth. There are many variable processes available at the spinning and .

The textile industry is primarily concerned with the design, production and distribution of yarn, cloth and clothing. The raw material may be natural, or synthetic using products of the chemical industry.
The product layout is the opposite of the process layout. Rather than have a specific section for each group of tools and supplies, the product layout is an assembly line.
