Textile manufacturing

Textile manufacturing is a big and important industry. It turns fibre into yarn, and then into fabric. This fabric is often dyed or printed. Then it is made into cloth. The cloth can be used to make many things like clothing, household items, upholstery, and other products.

One of the most common fibres used is cotton. Many people like to wear cotton because it is comfortable. There are many steps in making textiles, from spinning the yarn to creating the fabric and adding colours. These steps help make many products that people use every day.

History

Textile manufacturing began as a craft done in homes. For many centuries, people in places like India, Egypt, China, and Africa made their own clothes by hand. In the 1700s and 1800s, machines changed how fabrics were made. Since then, new discoveries in science and technology have kept improving the way we make textiles. The first book about making fabric was called "A Treatise on the Art of Weaving" by John Murphy.

Processing of cotton

Cotton is the world's most important natural fibre. It is grown where there are long, hot, dry summers with plenty of sunshine and low humidity.

There are six stages to the manufacturing of cotton textiles:

• Cultivating and Harvesting
• Preparatory Processes
• Spinning
• Weaving or Knitting
• Finishing
• Marketing

After harvesting, the cotton goes through several steps to become yarn and fabric. It is cleaned, spun into yarn, and then woven or knitted into cloth. The fabric can then be dyed, printed, and made into various products like clothing and household items.

Processing of other vegetable fibres

Flax

Main article: Flax

Flax is a plant fibre from the Linum usitatissimum plant. After the plant is harvested, it goes through steps like retting, breaking, scutching, and hackling before being treated like cotton.

Jute

Main article: Jute

Jute is a plant fibre from Corchorus plants. It is retted, dried, and baled. A little oil is added when spinning it, and it can be bleached and dyed. Jute was used for sacks and bags but is now often used for carpets. It can also be mixed with other fibres to make new fabrics.

Hemp

Main article: Hemp

Hemp is a fibre from the Cannabis sativa plant. It is hard to bleach and is mostly used for cord and rope. It goes through retting, separating, and pounding.

Other bast fibres

Other plant fibres used for eco-friendly textiles include kenaf, ramie, nettle, and urena.

Other leaf fibres

Sisal is the main fibre from leaves, with others being abacá and henequen.

Processing of wool and silk

Wool

Wool comes from sheep and is used to make two types of yarn: woolens and worsteds. Woolens have fibres arranged sideways, making soft yarn that traps air. Worsteds have fibres lined up, creating strong and smooth yarn.

Sheep can have different types of wool coats. Some have a soft under layer and a tougher outer layer, which can be processed separately or mixed together. Virgin wool is wool that has never been used before. The wool is cut off the sheep in one piece and cleaned before being made into yarn.

Silk

Silk comes from silkworms and is processed in ways similar to cotton. Silk is sorted, washed, and dried. It is then twisted and stretched to make it strong enough for weaving. The silk is dyed and woven into fabric using special machines.

Environmental consequences of wool and silk manufacture

Making wool and silk needs land. Silkworms eat mulberry leaves, while sheep eat grass and other plants. Sheep, like other animals that chew their food slowly, release CO₂ into the air. Their pastures sometimes use fertiliser, which can also increase emissions.

Processing of synthetic fibres

Main article: Synthetic fibre

Synthetic fibres are special materials made by scientists. They help improve on natural fibres from animals and plants. These fibres are made by pushing materials through small holes, called spinnerets, to form threads. Before synthetic fibres, people used natural cellulose from plants to make fibres.

The first artificial fibre, called art silk, was developed in 1799. It later became known as viscose around 1894 and then rayon in 1924. Another fibre, cellulose acetate, was discovered in 1865. Rayon and acetate are made from wood, so they are not truly synthetic. Nylon, the first fully synthetic fibre, appeared in the United States as a replacement for silk. It was used for important items like parachutes.

The way these fibres are turned into yarn is similar to natural fibres. But changes are needed because synthetic fibres are very long and lack the natural texture that helps fibres mesh together. Unlike natural fibres, synthetic fibres are made from fossil fuels, so they do not need farmland.
