A wool fiber can be bent back on itself more than 20,000 times without breaking, compared to about 3,000 times for cotton and 2,000 times for silk. The natural elasticity of wool also makes woolen fabrics resistant to tearing. In addition, the outer skin of the wool fiber acts as a protective film, giving wool cloth improved resistance to abrasion.
Wool is the textile fiber obtained from sheep and other animals, including cashmere and mohair from goats, qiviut from muskoxen, from hide and fur clothing from bison, angora from rabbits, and other types of wool from camelids; additionally, the Highland and the Mangalica breeds of cattle and swine, respectively, possess wooly coats.Wool consists of protein together with a few percent lipids.
Wool products labeling Act permits the word “wool” to be used for fibers from sheep, Angora or Cashmere goats, camel, alpaca, llama, and vicuna. Summary. Wool is a protein fiber that comes from a variety of animals. Sheering is done by hand, but the manufacturing of wool fabric is done by machine.
Wool characteristics. Woolcheque uses a combination of objective and subjective wool measurements and characteristics to price wool. Objective measurements include diameter (micron), length, strength, position of break, vegetable matter and colour. AWEX-ID covers subjective characteristics.
Dyeing ability: Wool fiber could be dyed by basic dye, direct dye and acid dye. It is noted that; all the wool fiber is not same in characteristics. It varies depending on the wool’s country of origin and sheep type. So, choose your wool fiber after confirming about the physical and chemical properties of wool fiber.
The term merino is widely used in the textile industries, but it cannot be taken to mean the fabric in question is actually 100% merino wool from a Merino strain bred specifically for its wool. The wool of any Merino sheep, whether reared in Spain or elsewhere, is known as "merino wool".
Characteristics of Fiber ... For example: woolen yarns - made from all lengths of the fiber (carded wool) is usually spun in a low twist yarn. Worsted yarns were spun from the long fibers only (combed into top with fibers parallel) into a high twist yarn that is usually denser and smoother, making a cooler, but wind resistant fabric. ...
Wool fiber is the natural hair grown on sheep and is composed of protein substance called as keratin. Wool is composed of carbon, hydrogen, nitrogen and this is the only animal fiber, which contains sulfur in addition. The wool fibers have crimps or curls, which create pockets and give the wool a spongy feel and create insulation for the wearer.
Wool absorbs many dyes deeply, uniformly, and directly without the use of chemicals. This characteristic allows wool to achieve very beautiful and rich colors when dyed. Durability. The flexibility of wool makes it very durable. A single wool fiber can be bent back on itself more the 20,000 times without breaking.
