A fiber can be described as any substance natural
or manufactured that is suitable for being processed
into a fabric. Fiber properties include length (staple
or filament), size and surface contour. These
properties affect the end use such as serviceability,
aesthetics, durability, comfort, retention and care.
To create a fabric, fibers are spun into yarns and
then woven into fabric. Through these processes a
fabric’s characteristics can be manipulated through
blending, manipulation of the fiber and other
methods. Look through a microscope and the secret
to any fabric is beneath the surface.
Filament Fibers:
All fibers having a practically unlimited or infinite length are called filaments. Filament fibers are continuous (long) fiber. It may be natural like silk or synthetic like Nylon.
Filament fibers are measured in yards or meters. Silk, in filament form is reeled from cocoons. Man-made fibers of a chemical composition, liquid nature are forced through spinnerets, hardened and produced into continuous filament strands of a determined length. When filament fibers are planned to be cut into staple fibers, a large spinnerets with many openings are used. The filament fibers are grouped into a bundle referred to as a tow and then cut into the desired staple length. Line or low man-made fibers are manufactured in continuous strands of any desired length. The tows may be cut into staple lengths, or flocks based on specific end use.
Staple Fibers:
Any fiber with a practically limited or finite length is called “Staple Fiber” These are small length fiber like cotton, wool, jute etc. it may be natural (Cotton) or man-made (Viscose rayon, Polyester).
The length of the fiber varies within a fiber of the same source and also between varieties obtained from different sources. Staple fibers are measured in inches or centimeters. Staple fibers include almost all natural fibers except silk. Silk is a natural filament fiber and may be cut up to form short staple fibers. Staple fibers must be spun or twisted together to make a long continuous strand of yarn. They may also be used in their staple form to produce non woven or felted fabrics.
Staple is fiber of cotton, wool or ramie etc of no more than a few inches long. Filament is usually a man-made fiber of indefinite length. All fabrics woven, knitted or crocheted are made from yarn. The size of yarn is usually related the weight of the fabric eg. heavy fabrics use thick yarns, for light fabrics fine yarn is used. There are 2 kind of yarns used in textile fibers they are spun yarn and filament yarn and use 3 different systems to control the size.
