How is wool made into fabric?
To be made into fabric, wool undergoes several processes. The fleece is sheared from the sheep, scoured, carded, combed and spun into yarn. The yarn is then woven on a loom to create wool fabric. There are two types of wool yarn that make different fabrics: woolen and worsted.
How is yarn woven?
The yarn is woven into fabric on looms, computerized machines that work at high speeds to interlace horizontal and vertical sets of threads, forming a flat cloth. A set of parallel warp (vertical) threads are held taut by the loom while weft (horizontal) threads are held in a shuttle.
How is worsted wool spun?
Spinning. Woolen and worsted wool are both processed by machines that draw out the ends of the fibers and spin them together by twisting at high speeds. The yarn can be spun into different thicknesses and strengths by varying the tension and direction of the twisting motion.
What is fleece graded?
The fleece is examined and graded according to the length, diameter, strength, crimp and color of its individual fibers. Finer wool is used to make worsted fabric for suits and other garments, while coarser wool is made into woolen fabric for coats, jackets and rugs. Fleeces of the same grade are mechanically pressed into bales ...
What is the process of making worsted yarn?
The Worsted Process: Combing . Finer, longer wool fibers are used to make worsted yarn, which makes a smooth, soft fabric. The carded wool is combed and drawn by passing over a series of tines to remove shorter fibers and comb long ones parallel, forming a long continuous rope called a sliver.
What is carding wool?
Carding. The mixed and washed wool consists of tufts of tangled fibers. A carding machine smoothes the fibers by brushing the wool over a series of rolling drums covered in pointed teeth. The drums are different sizes and rotate at different speeds, so as the wool progresses its fibers are aligned into a fine web.
Can wool be dyed?
Wool can be dyed before carding or after being spun into yarn, or the finished fabric can be dyed. Fabric is treated with heat, moisture and friction to tighten the weave and shrink the fabric. To make the fabric fleecy, it is brushed to raise the nap, giving a fluffy finish.
How is wool made before spinning?
Before the newly formed wool top can enter the spinning stage, it has to be made some 40 times thinner by ‘drawing’ it down into a fine sliver, called a roving. The roving is then ‘spun’ to form a worsted yarn.
How are non-woven fabrics made?
The production of non-woven fabrics requires methods to form layers of fibres into coherent fabrics without the need to spin yarns. Although most non-woven methods of fabric formation are relatively new, one of the techniques available to make non-woven wool fabrics — felting — has been used for many years and used by many early cultures.
What is the longest wool fibre?
Fleece wool generally contains the longest wool fibres, which vary less in diameter and length. Worsted yarn is used to make flatter, lighter and smoother fabrics such as those used for traditional tailoring. Blending.
What is wool yarn?
Woollen yarn is usually created from the shorter fibres of the sheep's fleece. These wool fibres vary more in diameter and length. Woollen yarn is used to make thick, heavyweight woven or knitted garments. These fabrics are ideal for warm winter jackets or sweaters.
What is woollen carding?
The carding action in woollen carding is similar to worsted carding where the wool is fed into the carding machine where wire-covered rollers separate the fibres, except: mixing of the wool (blending) is encouraged by cross-lapping the sliver formed and re-carding the cross-lapped layer in the second part of the card.
How to bind yarn together?
Insert sufficient twist into the yarn to bind the fibres together, so it is strong enough to withstand the strains of subsequent processing.
How many times does wool stretch before spinning?
the slubbings from the woollen card are given only a little stretch before twisting — just enough to maintain cohesion. This contrasts to the 20–30 times stretch used in worsted spinning
What was the process of turning wool into cloth?
Methods could vary depending on the wherewithal of the producer, but the basic processes of spinning, weaving, and finishing cloth were essentially the same.
What was used to clean wool?
Next, the wool was washed; soap and water would usually do for worsteds. For the fibers that would be used to make woolens, the cleansing process was particularly stringent and could include hot alkaline water, lye, and even stale urine. The aim was to remove the "wool grease" (from which lanolin is extracted) and other oils and greases as well as dirt and foreign matter. The use of urine was frowned upon and even outlawed at various points in the Middle Ages, but it was still common in home industries throughout the era.
What was the purpose of wool combs?
For worsted yarn, simple wool combs were used to separate and straighten the fibers. The teeth of the combs might be wooden or, as the Middle Ages progressed, iron. A pair of combs was used, and the wool would be transferred from one comb to the other and back again until it had been straightened and aligned.
What is pulled wool?
Occasionally, the skin of a slaughtered sheep was utilized for its wool; but the product obtained, which was called "pulled" wool, was an inferior grade to that shorn from live sheep. If the wool was intended for trade (as opposed to local use), it was bound up with similar fleeces and sold or traded off until it reached its final destination in ...
Why is fleece separated into different grades?
The first thing done to a fleece was to separate its wool into its various grades by coarseness because different types of wool were destined for different end products and required specialized methods of processing. Also, some types of wool had specific uses in the manufacturing process itself.
What was more common than knitting in the Middle Ages?
Far more common than knitting in the Middle Ages was weaving.
When was the horizontal loom invented?
The horizontal loom made its first appearance in Europe in the 11th century, and by the 12th century, mechanized versions were being used. The advent of the mechanized horizontal loom is generally considered the most important technological development in medieval textile production.
The process of wool manufacturing
Wool is manufactured from the raw fibre into yarn via either the woollen or worsted processing system. Yarn is then manufactured into knitted and woven wool textiles and products.
Learn about wool manufacture
Learn more about wool processing and manufacturing on the Woolmark Learning Centre. Free to access, these intuitive online courses will further your education on wool fibre science, how wool is processed and how fabrics are finished and dyed.
What is wool made of?
What is wool? Wool is a protein fiber derived from the fleece of sheep and other animals and it is also the fabric made from the wool fibers. There are about 100 or more species of sheep that gives fleece that gets to be wool with varying degrees of perfection in length, fineness and colour. But it is not sheep alone that gives wool.
How are wool fibers separated?
The fibers are then processed in a carding machine, which pulls it straight. Here the fibers are separated into long and short fibers. The manufacturing process in which the short fibers (noils) are separated from the longer fibers which are combed into a continuous strand of parallel fibers called top is called combing. The short wool fibers removed in the combing process are called Noils.
What is the name of the wool that is sorted according to its length, color, and fineness?
The fleece thus obtained is then sorted according to their length, colour and fineness (quality). Separating fleeces into groups according to fineness and length is called grading of wool. Fine, Medium, Crossbred, Long, and Coarse are the basic types of categorization. At this point, the wool is called Raw wool.
Why is wool so fuzzy?
Large amounts of shorter wools, such as noils, wool wastes, and reworked wools are also used in addition to virgin wool. As the woolen yarn is not combed, the fibers lie in an uneven fashion. This is the reason for the fuzzy texture of the woolen fabric. Woolen fabrics are generally weaker than worsted fabrics.
Why is wool good for keeping you warm?
This can keep a person warm when wearing wool because wool removes moisture from the skin. Insulating capacity and Climate control.
Why is wool not attracted to dirt?
Lint, dirt, and dust are not attracted to wool because it repels static. As said it even resists spills
What is sheep wool?
Sheep can be categorized according to the kind of fleece they give. Fine wool sheep gives the finest of wool. The carpet wool sheep gives a coarse fur, the kind that is used in making carpets. The wool obtained at the first shearing after 6 months is called Lambswool. Wool obtained in the first or second shearing after 10 to 12 months is called yearling wool.When wool is taken from a healthy living sheep it is called virgin wool but when it is taken from a sheep that have died from natural cause it is called fallen wool. Wool from slaughtered sheep is called skin wool.
Why does wool fabric scratch?
It mostly comes down to two factors: fiber diameter and fiber length. When wool fabric is placed against the body, the scratchiness is actually created by all the ends of the wool fibers. If the fiber is thin enough, it will bend away when it touches the skin. If it is thick, it remains rigid, registering as a tiny poke.
What makes wool so warm?
As a fabric, wool has a variety of properties that make it as attractive a material today as it was a thousand years ago. Molecularly, wool fibers are tiny coils, which look like little springs. This makes them highly elastic and allows them to bounce back into shape even after lots of stretching. The coil structure also creates lots of space to trap air and moisture. This is what makes wool warm, but not overly so. Wool is also hydroscopic, meaning it can absorb up to thirty percent of its own weight in water without feeling damp. It’s one of the only fabrics that will still keep you warm when wet, and its naturally high moisture and nitrogen content means that it is extremely flame-resistant.
Why is wool called greasy wool?
Next, the wool must be washed. Raw wool is also called greasy wool, because it is soaked with lanolin. Even just touching it leaves a residue on your hands. The naturally occurring lanolin helps protect the sheep and keep water out; however, it has a rather pungent smell and isn’t desirable in the finished yarn. Not everyone in history agrees on this, though. The well-known Irish fisherman sweaters used to be made with greasy wool. The combination of the lanolin and the minor felting that happened with the ocean damp created a garment that was practically waterproof, if rather stinky.
How long has wool been around?
For thousands of years, the story of wool has been entwined with that of humanity’s. People began to domesticate sheep nearly 10,000 years ago after realizing that they could provide both food and clothing. The herd animals could easily move with nomadic tribes, and their resiliency and ability to eat woody plants meant they could survive in conditions many other animals could not.
How did the wool industry change?
In the following years, the wool industry grew with the onset of the Industrial Revolution, rising to meet the demands of an exploding population with ever increasing purchasing power. Wool began its steady decline following the invention of synthetic fibers in the mid-twentieth century. By the end of the 1990s, the US wool industry had collapsed to half its size. Unable to compete with cheaper overseas production and the emergence of competing wool markets, many sheep farming operations were shuttered. Today, the industry is dominated by Australia, China, and New Zealand, where sheep outnumber citizens five to one.
How many sweaters can you make from a fleece?
The whole process starts with a fleece, which is the wool from one sheep shorn in a single piece. One average-sized fleece could make about two adult sweaters. First, the unusable parts are removed. These are usually the skirtings, dirty, short-fibered portions, which are around the legs and underbelly of the animal. Kim and Jane stuff the skirtings into burlap bags and use them like sandbags to control erosion around the farm. The wool felts inside the bag and the burlap rots away, leaving something behind that looks disconcertingly like a giant hairball.
Why do sheep have fleece?
Because of wool’s insulating properties , sheep with an inch of fleece are actually cooler than sheep with no fleece. Sheep are unable to sweat; they pant like dogs when their body temperature gets too high, so overheating must be avoided.
