Early experiments[ edit ] Joseph Swan created the first synthetic fiber. Joseph Swan invented the first artificial fiber in the early s;  today it would be called semisynthetic in precise usage. His fiber was drawn from a cellulose liquid, formed by chemically modifying the fiber contained in tree bark.
Other types of fiber that felt fairly easily are Alpaca, Angora, Mohair, and Llama. There are many different breeds of sheep and the wool from each breed has different qualities and characteristics. Learning about the various differences will be a great help when determining which type of wool should be used for which individual project.
Fibre from Alpacas and Angora goats is softer the younger the animal. The softness of the fibre also depends where on the animal it was sheared from. Alpaca fibre is very soft and has a silky feel.
Kid mohair is from the youngest goats and is softer and more curly. Mohair is very shiny. The micron count for cria alpaca and kid mohair is around 20 for both, increasing with the age of the animal. Other micron counts are CashmereAngora rabbitVicunaCamel Wool has characteristics that have made it a desirable fiber for many thousands of years.
Wool is an insulator as opposed to trapping heat. As an insulator, it keeps you warm in cold weather and cool in hot weather. The moisture in each wool fiber means that it is fire resistant. Wool will char in an open flame but is self extinguishing and stops burning after being removed from the flame.
The waviness or crimp of wool fiber gives it a natural elasticity. Wool is resistant to dirt because the small scales on the surface of the fiber hold the dirt near the surface, making the dirt easier to remove.
Wool also repels odors. Due to its moisture content, wool is resistant to static electricity. Saving the best for last, wool has the ability to felt.
Due to the small scales on the surface of the wool fiber as well as other factors such as the crimp, wool when combined with warm water, soap and a little agitation will matt together in an irreversible process called felting.
Wool is graded to determine its quality. The quality can be determined by fiber diameter, crimp, color, staple length, staple strength, yield and remaining vegetable matter.
The most important factor though is the fiber diameter. The fineness or coarseness of the wool will determine its end use. The diameter is measured either by the Bradford System or by microns.
The Bradford System is a way to measure the fineness of a wool breed.
The Bradford Count is the number of hanks of yarn a hank being yards long that can be spun from a pound of wool tops. The finer the wool, the more hanks could be spun.
Wool with higher Bradford counts are finer and therefore can be spun into longer yarn. Micron count is the diameter of the fibre in microns, a micron is 1,th of a millimetre. The lower the micron count the finer the wool. The link below is a PDF file of a list of common sheep breeds with average Bradford and micron diameter measurements.

Synthetic polymer fibers polyester, Plastics go on a natural-fiber diet. For example, fibers such as cotton, and linen are plant-based fibers- they grew from the ground. Wool comes from sheep, and silk from silkworms, and so they are described as animal-based fibers.
However, fabrics such as rayon and polyester are referred to as synthetics. PUBLIC HEALTH STATEMENT Synthetic Vitreous Fibers Division of Toxicology September This Public Health Statement is the summary chapter from the Toxicological.
A great advantage of synthetic fibers is that they are more durable than most natural fibers.
In addition, many synthetic fibers offer consumer-friendly functions such as stretching, waterproofing and stain resistance. Overtime, things like sunlight and oils from human skin cause fibers in various. Why synthetic fibres should be used over animal fibre? Update Cancel.
ad by TruthFinder. What is the reason we use synthetic fibres more than natural fibre? Why shouldn't we replace animal fibres with synthetic fibres? What are human made or synthetic fibres? Jan 09, · Synthetic fibres are very durable and do not wrinkle easily; They are elastic and can be easily stretched out; They are strong and can sustain heavy load.
It is soft and hence it is used in clothing material. It is cheaper as compared to natural fibres. Disadvantages of synthetic fibres.
Most synthetic fibres do not absorb moisture.
