A long, thin filament with a length at least 100 times its diameter. Fibers are used to make fabric, paper, mats and as fillers and strengtheners in composite materials. Synthetic fibers can often be produced very cheaply and in large amounts compared to natural fibers, but for clothing natural fibers have some benefits, such as comfort, over their synthetic counterparts.

Sources of fibers are:  
+
Examples of each type include:
 +
* [[Animal fibers|Animal]]: [[wool]], [[alpaca]], [[mohair]], [[angora]], [[silk]].
 +
* [[Vegetable fiber|Vegetable]]: [[abaca]], [[coir]], [[cotton]], [[hemp]], [[jute]], [[kapok]], [[kenaf]], [[linen]], [[Piña]], [[ramie]], [[sisal]]
 +
* [[Synthetic fiber|Synthetic]]: [[acetate%20fiber|Acetate]], [[acrylic%20fiber|Acrylic]], [[alginic%20fiber|Alginic]], [[anidex%20fiber|Anidex]], [[aramid%20fiber|Aramid]], [[azlon%20fiber|Azlon]], [[casein%20fiber|Casein]], [[cellulose%20nitrate|Cellulose nitrate]], [[cupro%20fiber|Cupro]], [[nylon%20fiber|Nylon]], [[novoloid%20fiber|Novoloid]], [[nytril%20fiber|Nytril]], [[modacrylic%20fiber|Modacrylic]], [[modal%20fiber|Modal]], [[olefin%20fiber|Olefin]], [[polyester%20fiber|Polyester]], [[Polyethylene fiber|polyethylene]], [[Polypropylene fiber|polypropylene]], [[rayon fiber|Rayon]], [[saran%20fiber|Saran]], [[spandex%20fiber|Spandex]], [[sulfar|Sulfar]], [[triacetate%20fiber|Triacetate]], [[vinal%20fiber|Vinal]], and [[vinyon%20fiber|Vinyon]].
 +
* Inorganic ([[Mineral fiber|Mineral]]): [[asbestos]], [[glass fiber|Glass]], [[carbon fiber|Carbon]], [[graphite fiber|Graphite]], [[steel]], [[tungsten wire|Tungsten]].
  
−
- animal: [[wool]], [[alpaca]], [[mohair]], [[angora]], and [[silk]].
+
The types of fiber are characterized as:
  
−
- vegetable: [[cotton]], [[kapok]], [[linen]], [[hemp]], [[jute]].  
+
* staple: short fibers.
 +
* [[monofilament|monofilaments]]: continuous single fibers.
 +
* [[tow]]: a continuous strand of bundled but untwisted fibers.
 +
* [[yarn]]: a continuous strand of twisted fibers.
  
−
- synthetic: [[rayon fiber|rayon]], [[nylon fiber|nylon]], [[acetate fiber|acetate]], [[polyester fiber|polyester]], [[acrylic fiber|acrylic]].
+
Physical characteristics of fibers include:
 +
* shape, strength, elasticity, flexibility, weight, stability and ability to absorb moisture
  
−
- mineral: [[asbestos]], [[glass fiber|glass]], [[carbon fiber|carbon]], [[tungsten]].

Coiled fiber basket
MFA# 99.134

Description

A long, thin filament with a length at least 100 times its diameter. Fibers are used to make fabric, paper, mats and as fillers and strengtheners in composite materials. Synthetic fibers can often be produced very cheaply and in large amounts compared to natural fibers, but for clothing natural fibers have some benefits, such as comfort, over their synthetic counterparts.

Examples of each type include:

The types of fiber are characterized as:

  • staple: short fibers.
  • monofilaments: continuous single fibers.
  • Tow: a continuous strand of bundled but untwisted fibers.
  • Yarn: a continuous strand of twisted fibers.

Physical characteristics of fibers include:

  • shape, strength, elasticity, flexibility, weight, stability and ability to absorb moisture
