Cellulose is a carbohydrate and the chief component in the walls of plants. Rayon is the oldest manufactured fiber, having been in production since the s in France, where it was originally developed as a cheap alternative to silk. Most rayon production begins with wood pulp, though any plant material with long molecular chains is suitable. There are several chemical and manufacturing techniques to make rayon, but the most common method is known as the viscose process. This substance gives its name to the manufacturing process, called the viscose process.

Synthetic Fibers: The Manufacturing Process and Risks to Human and EnvironmentVIDEO ON THE TOPIC: DIY Weaving - How To Make Everything: Suit (5/10)
Clothes today are made from a wide range of different materials. Traditional materials such as cotton, linen and leather are still sourced from plants and animals. But most clothes are more likely to be made of materials and chemicals derived from fossil fuel-based crude oil.
The source of synthetic fibres and fabrics is the fossil fuel crude oil. One of the oldest used fibres and the most important non-food crop in the world is cotton. Cotton production is particularly important for farmers in lower-income countries, where approximately million people are involved in its cultivation and processing 4.
These materials begin as cellulose extracted from a natural resource such as bamboo or trees that is then crushed, pulped and transformed into fibres using a similar process to the one for making polyester. The most common cellulosic fabric is viscose, prized for its silk-like qualities rayon, the first type of viscose fabric invented, was created to mimic silk.
About 2bn kilograms of raw wool per year are produced from a global herd of around 1. This roughly equates to one wool sweater per person per year for everyone on the planet 6. These figures include wool textiles used for items other than garments — such as furniture or carpets. An ancient, highly prized fabric, silk is derived from the thread produced by the silkworm species Bombyx Mori.
About , MT of silk are produced each year about 0. This is one of the oldest forms of material used by humans as clothing and it remains an important fabric particularly for footwear and accessories. Around 3. Bast fibres like flax for linen , hemp and nettle are a traditional source that has been used by humans for thousands of years, although they presently make up only a small proportion of total fabric use.
These fibres are found in the inner bark layer phloem , of the plant that sit between the woody core xylem , and the outer-most layer epidermis. The long phloem cells must be separated from the xylem and epidermis before being further treated to make them ready to weave or knit into fabrics 11 , either as a pure fibre or in a mix with other fibres such as cotton.
Most bast fibres are used for other products such as paper, ropes and carpets. This is a broad category of fibres and materials that are diverse but make up only a tiny fraction of the entire amount of fabrics used. Many of these are experimental in nature — for example, they may be made from materials originally derived from mushrooms 12 , pineapple 13 or milk.

Clothing Industry. Man Made Fibre Manufacturing Process. A pplication of fibers in textiles and clothing starts from the development of human evolution. Clothing became existence, not for aesthetic purpose or decoration but for protection against cold, hot, rain, dust, etc. Generally two types of fiber are used to manufacture fabric; they are natural fiber and manmade fiber. In this article I will discuss about man made fiber.

Man Made Fibre Manufacturing Process
For centuries humankind has relied upon various plants and animals to provide the raw materials for fabrics and clothing. Silkworms, sheep, beaver, buffalo deer, and even palm leaves are just some of the natural resources that have been used to meet these needs. However, in the last century scientists have turned to chemistry and technology to create and enhance many of the fabrics we now take for granted. There are two main categories of man-made fibers: those that are made from natural products cellulosic fibers and those that are synthesized solely from chemical compounds noncellulosic polymer fibers.SEE VIDEO BY TOPIC: Polyester Yarn Manufacturing Process
Polymer that is to be converted into fibre must first be converted to a liquid or semiliquid state, either by being dissolved in a solvent or by being heated until molten. This process frees the long molecules from close association with one another, allowing them to move independently. The resulting liquid is extruded through small holes in a device known as a spinnerette , emerging as fine jets of liquid that harden to form solid rods with all the superficial characteristics of a very long fibre, or filament. This extrusion of liquid fibre-forming polymer, followed by hardening to form filaments, is called spinning a term that is actually more properly used in connection with textile manufacturing. Several spinning techniques are used in the production of man-made fibre, including solution spinning wet or dry , melt spinning, gel spinning a variant on solution spinning , and emulsion spinning another variation of solution spinning. One of the oldest methods for the preparation of man-made fibres is solution spinning, which was introduced industrially at the end of the 19th century. Solution spinning includes wet spinning and dry spinning. The former method was first used to produce rayon fibres, and the latter method was used to spin cellulose triacetate to acetate fibres.
Textile manufacturing is a major industry. It is based on the conversion of fibre into yarn , yarn into fabric. These are then dyed or printed, fabricated into clothes.

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. Animal fibres consist of proteins. 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.
Principles and Methods of Modification of Fibres and Fibre Materials. A Review
In this modern era with the improvement in technology, people can realize that they can only survive, if ournature survives. So scientists are trying their best to cooperate with our mother like environment by reducing the amount of waste product. Again people are very conscious about different diseases even if while dressing themselves up. Again there are some techniques of producing casein fiber which are beyond any kind of harm to the environment. So this article is very well suited with the modernization of the textile sector. This article will help the researchers to reach the casein fiebr at a very remarkable stage of use as textile garments. Keywords: Sustainability, Eco friendly, Qmilk, Drawbacks etc. Nishat Tasnim M.

How is fabric created?
We have been manufacturing fibers from the renewable raw material wood for about 80 years. We have also secured a leadership position in the 21st century thanks to a passion for our products and technological know-how. We have adapted it to the ecological demands of the 21st century by achieving high recovery rates for chemicals. On the other hand, we implement the most advanced closed-loop lyocell production process.
The textile process
Chemical fibers global production 2000-2018
Thanks to the technical progress in the field of chemical fibres and textiles made from them, in addition to the traditional kinds of first-generation chemical fibres and fibre materials, new types with optimized properties based on the wide use of methods of physical, composite, and chemical modification — second-generation fibres and fibre materials textiles — have been created. This significantly affected the evolution of production of different kinds of fibres by partially altering the ratio of the production volumes. Modified types of fibres, filament, and fabrics for industrial use are also manufactured, for example, for reinforcing mechanical rubber goods, fireproofing, antimicrobials, etc.
