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.

Textile manufacturing by pre-industrial methodsVIDEO ON THE TOPIC: How to Harvesting Wool - Amazing Sheep Factory - Wool Processing Mill
As with many discoveries of early man, anthropologists believe the use of wool came out of the challenge to survive. In seeking means of protection and warmth, humans in the Neolithic Age wore animal pelts as clothing. Finding the pelts not only warm and comfortable but also durable, they soon began to develop the basic processes and primitive tools for making wool. By B. People soon began to develop and maintain herds of wool-bearing animals. The wool of sheep was soon recognized as one of the most practical to use.
During the eleventh and twelfth centuries, wool trade prospered. The English had become proficient in the raising of sheep, while the Flemish had developed the skills for processing. As a result, the British began to sell their wool to the Flemish, who processed the raw material and then sold it back to the English. The ambitious British soon realized the advantages of both producing and processing their own wool. As Britain began to prosper, it sought to enhance its position by enacting laws and embargoes that would stimulate its domestic production.
Some laws, for example, required that judges, professors, and students wear robes made of English wool. Another law required that the dead be buried in native wool. When the American colonies began to compete with the motherland, the English passed a series of laws in an attempt to protect their "golden fleece.
Today, wool is a global industry, with Australia, Argentina, the United States, and New Zealand serving as the major suppliers of raw wool. While the United States is the largest consumer of wool fabric, Australia is the leading supplier. Australian wool accounts for approximately one-fourth of the world's production. What for centuries was a small home-based craft has grown into a major industry.
The annual global output is now estimated at 5. Though cotton is the number one plant used for fabrics and the number one fiber overall, the number one source for animal fiber is still wool. While most people picture only sheep when they think of wool, other animals also produce fine protein fiber. Various camels, goats, and rabbits produce hair that is also classified as wool. In scientific terms, wool is considered to be a protein called keratin. Its length usually ranges from 1.
Each piece is made up of three essential components: the cuticle, the cortex, and the medulla. The cuticle is the outer layer. It is a protective layer of scales arranged like shingles or fish scales. When two fibers come in contact with each other, these scales tend to cling and stick to each other.
It's this physical clinging and sticking that allows wool fibers to be spun into thread so easily. The cortex is the inner structure made up of millions of cigar-shaped cortical cells. In natural-colored wool, these cells contain melanin. The arrangement of these cells is also responsible for the natural crimp unique to wool fiber. Rarely found in fine wools, the medulla comprises a series of cells similar to honeycombs that provide air spaces, giving wool its thermal insulation value.
Wool, like residential insulation, is effective in reducing heat transfer. Wool fiber is hydrophilic—it has a strong affinity for water—and therefore is easily dyed. While it is a good insulator, it scorches and discolors under high temperatures. Each fiber is elastic to an extent, allowing it to be stretched 25 to 30 percent before breaking. Wool does, however, have a tendency to shrink when wet.
While some of the characteristics of wool can be altered through genetic engineering of sheep, most of the modifications of design are implemented during the manufacturing of the fabric. Wool can be blended with any number of natural or synthetic fibers, and various finishes and treatments can also be applied.
Different types of fleece are used in producing wool. Lambs' wool is fleece that is taken from young sheep before the age of eight months. Because the fiber has not been cut, it has a natural, tapered end that gives it a softer feel. Pulled wool is taken from animals originally slaughtered for meat and is pulled from the pelt using various chemicals. The fibers of pulled wool are of low quality and produce a low-grade cloth.
Virgin wool is wool that has never been processed in any manner before it goes into the manufacturing phase. This term is often misunderstood to mean higher quality, which is not necessarily the case.
These wools and others can be used in the production of two categories of woolen fabrics: woolens and worsteds. Woolens are made up of short, curly fibers that tend to be uneven and weak. They are loosely woven in plain or indistinct patterns. Usually woolens have a low thread count and are not as durable as worsteds. They do, however, make soft, fuzzy, and thick fabrics that are generally warmer than their counterparts. The deep wrinkles on imported A-type Merino ewes left and rams right contributed to increased wool yields per sheep for American wool producers.
The mechanization of the woolen cloth industry provides a heady example of the extent of nineteenth-century industrial change. Every step of the process, except shearing the sheep and sorting the wool into different grades, was mechanized between and Only the organic aspects of shearing live animals and the value judgments required of human sorters resisted mechanical replication until the twentieth century.
Growth of the American woolen trade was based on more than mechanical change, however. In the seventeenth and eighteenth centuries, American sheep provided wool that was quite satisfactory for "homespun," the rough, durable cloth woven by hand on looms owned by professional weavers who set up shop or moved from town to town with their looms. But domestic cloth was overshadowed in quality by imported material. Several varieties of sheep bred in England and Europe produced wool vastly superior in quality to American-produced wool.
The importation of breeds such as the English Southdowns and Spanish Merinos improved domestic quality and allowed the American woolen industry to compete with the best imports. The Merino sheep, in particular, with their deeply wrinkled folds producing large quantities of wool, caused a stir among American farmers in the early part of the century. A few "gentlemen farmers" avoided Spanish export restrictions and imported some Merinos.
As wool prices rose during the embargo of , a "Merino craze" occurred that pushed the price of fine wool and purebred animals to record levels. Then, in , an American diplomat arranged the importation of 20, purebred Merinos, and the woolen industry from Vermont to Pennsylvania to Ohio was changed forever.
Worsted fabrics are made of long, straight fibers with considerable tensile strength. They are usually woven in twill patterns and have a high thread count. The finish tends to be hard, rough, and flat. Also, the insulation Wool manufacture begins with shearing the sheep. After grading and sorting, the fleece is scoured in a series of alkaline baths containing water, soap, and soda ash or a similar alkali.
This process removes sand, dirt, grease, and dried sweat from the fleece. Next, the fleece is carded—passed through a series of metal teeth that straighten and blend the threads into slivers. Carding also removes residual dirt and other matter left in the fibers. Worsted fabrics also tend to be more expensive than woolens. The major steps necessary to process wool from the sheep to the fabric are: shearing, cleaning and scouring, grading and sorting, carding, spinning, weaving, and finishing.
Worsted yarns can create fine fabrics with exquisite patterns using a twill weave. The result is a more tightly woven, smooth fabric. Better constructed, worsteds are more durable than woolens and therefore more costly. The use of waste is very important to the wool industry. Attention to this aspect of the business has a direct impact on profits. These wastes are grouped into four classes:. The spun wool yarn is woven into fabric using two basic weaves: the plain weave and the twill weave.
Woolen yarns are made into fabric using a plain weave rarely a twill , which produces a fabric of a somewhat looser weave and a soft surface due to napping with little or no luster.
The napping often conceals flaws in construction. Most of the quality control in the production of wool fabrics is done by sight, feel, and measurement. Loose threads are removed with tweezer-like instruments called burling irons; knots are pushed to the back of the cloth; and other specks and minor flaws are taken care of before fabrics go through any of the finishing procedures.
The purpose of this act was to protect producers and consumers from the unrevealed presence of substitutes and mixtures in wool products.
This law required that all products containing wool with the exception of upholstery and floor coverings must carry a label stating the content and percentages of the materials in the fabric. This act also legally defined many terms that would standardized their use within the industry.
Some of the key terms identified in the Act are:. The current widespread use and demand for wool is so great that there is little doubt that wool will continue to maintain its position of importance in the fabric industry. Only a major innovation that encompasses the many attributes of wool—including it warmth, durability, and value—could threaten the prominence of this natural fiber.

Cotton fabric is one of the most commonly used types of fabrics in the world. This textile is chemically organic, which means that it does not contain any synthetic compounds. Cotton fabric is derived from the fibers surrounding the seeds of cotton plants, which emerge in a round, fluffy formation once the seeds are mature. The earliest evidence for the use of cotton fibers in textiles is from the Mehrgarh and Rakhigarhi sites in India, which date to approximately BC.
Natural wool is the fiber obtained from sheep and other animals. For example cashmere and the mohair of goats, Qiviut of muskoxen, angora of rabbits, and Camelid wool. Sheep wool is the most preferred because it has important physical properties distinguish it from camel hair, goat hair, and others. The wool is consists of protein with a low proportion of fat.

Textile manufacturing is one of the oldest human activities. The oldest known textiles date back to about B. In order to make textiles, the first requirement is a source of fibre from which a yarn can be made, primarily by spinning. The yarn is processed by knitting or weaving to create cloth.
The industrial revolution started in Great Britain in the mids. Textile production was the first great industry created. The early mills used the putting out system in which the mill did carding and spinning, but hand weavers were paid to weave the fabric then return it to the mill for finishing. Then, in the s, improved machinery allowed mills to do the entire process with machines, greatly reducing the cost of cotton cloth. In , power looms that could manage wool were developed and affordable woolens appeared. Continued advances in textile machinery and the spread of railroads soon made inexpensive factory-produced fabrics available everywhere. By , there were more than 2, woolen mills, and hundreds of cotton mills all over the United States. The mills completely changed how people dressed and the way they decorated their homes. By the s, ordinary people could afford more clothing and poorer people began to copy the fashions of the well to do. Curtains and other decorative textiles appeared in houses.

Every stitch of the sewing had to be done by hand; Elias Howe didn't even invent the sewing machine until , and Isaac Singer's version didn't come about until Of course, ordinary people didn't have the large wardrobes we expect today. They made do with one outfit for every day, one for Sunday best, and perhaps one other, or parts of another, for seasonal change. Even wealthy people didn't necessarily have lots of clothes, although their money allowed them to purchase ready-made items from the storekeeper, or to hire custom sewing done outside the household, or by a temporary live-in seamstress. Where a family lived determined to a great extent where and how they obtained their clothing. City and town dwellers usually purchased the fabrics, if not the entire garments, from specialty or general stores. People in rural or remote areas were more likely to undertake the whole process themselves. Still, it was possible for nearly anyone to order nearly anything to be sent to them from a merchant in the next town, or even from a merchant oceans away. It just took a very long time to arrive.
Types of Machines Used in Textile Industries
Lubricating oils are specially formulated oils that reduce friction between moving parts and help maintain mechanical parts. Lubricating oil is a thick fatty oil used to make the parts of a machine move smoothly. The lubricants market is growing due to the growing automotive industry, increased consumer awareness and government regulations regarding lubricants. Lubricants are used in vehicles to reduce friction, which leads to a longer lifespan and reduced wear and tear on the vehicles. The growth of lubricants usage in the automotive industry is mainly due to an increasing demand for heavy duty vehicles and light passenger vehicles, and an increase in the average lifespan of the vehicles. As saving conventional resources and cutting emissions and energy have become central environmental matters, the lubricants are progressively attracting more consumer awareness. Greases are made by using oil typically mineral oil and mixing it with thickeners such as lithium-based soaps. They may also contain additional lubricating particles, such as graphite, molybdenum disulfide, or polytetrafluoroethylene PTFE, aka Teflon.

A solvent is usually a liquid but can also be a solid or a gas. Solvents find various applications in chemical, pharmaceutical, oil, and gas industries, including in chemical syntheses and purification processes. Thinners are defined as chemical compounds that are introduced into the paint prior to application, in order to modify the viscosity and other properties related to the rate of curing that may affect the functionality and aesthetics of the final layer painting. Paint thinner, a solvent used in painting and decorating, for thinning oil-based paint and cleaning brushes.

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. Different types of fibres are used to produce yarn.
Textiles are a type of cloth or woven fabric; its creation involves several processes than one might think. The production of fibers are spun into yarns, and are then used to create fabrics into many other sub-processes.
