What are the two groups of manufactured fibers?
1.) Synthetic
2.) Natural Base
These fibers are meticulously engineered so they produce a better end product. They are man made not nature made.
Manufactured Fibers
What is the main advanatage to manufactured fibers?
You can control the fiber and enhance its qualities.
What is the 3-step fiber spinning process?
1.) Prepare viscous syrupy dope
2.) Protrude dope through spinneret to form fiber
3.) Solidify fiber by coagulation, evaporation, or cooling
What is the name of the object that you protrude dope through?
The Spinneret
The substance used to form solutions.
Raw Materials
Material from which a fiber is formed.
Spinning Solution
Forcing the dope through tiny holes in the spinneret.
This occurs when the polymer is dissolved by chemicals, spun into a bath, then coagulated.
Wet Spinning
When a polymer dissolved by a solvent is spun into warm air, and then the solvent evaporates.
Dry Spinning
When a polymer is metleted, spun into the air, and cooled.
Melt Spinning
Raw material dissolved in amine ocide, fiber spun into weak amine oxide solution, fiber precipitates out and solution is recycled.
Solvent Spinning
A fiber in its simplest form.
A Parent Fiber
Changes of the parent fiber relative to properties or chemical compositoin. Engineered for end use.
This is what controls the size of the spinneret opening....
Fiber Size
What are two forms of manufactured fibers?
1.) Cellulosic
2.) Protein
If something is "oleophilic" what does that mean?
It means that it has the ability to with stand moisture.
Disposing of moisture away from the fabric.
What was the first fully synthetic fiber and what was it used for?
Nylon, women's stockings
This was developed to replace rubber (spandex).
These came from plant materials and were then reformed.
Regenerated Cellulose Fibers
This is fiber is like a silky cotton, has a celulosic base, and is wet spun.
What are three examples of synthetic fibers?
1.) Rayon
2.) Lyocel
3.) Acetate/Triacetate
This fiber has a soft, fluid drape and a soft hand. It also has poor resilency and tends to shrink frequently.
Lyocel is ______ spun.
This fabric is a lot like cotton and has a cellulosic base. It also has strong durability and has a high level of comfort.
What is another name for protein? (Hint: This is no longer manufactured in the US).
This fiber may display unacceptable alterations of hand and color if washed in a regular cycle.
Acetate/Triacetate is _____spun.
Dry Spun
______ is no longer produced in the US because of all the chemical pollutants.
Acetate/Triacetate is _____, especially when wet.
______ is gas fading, and the fumes change the fiber color.
Acrylic is _____ spun.
Dry Spun
The problem with ______ is that there are knit bals at the end of the fiber strands.
Knit Balls
This fiber was originally supposed to be made like wool.
Polyester is _____ spun and hot drawn.
Melt Spun, Hot Drawn
This is made to be blended with all different fibers.
This is used in protective clothing because of its softeness and flame retardency.
Mod Acrylic
_____is often made to resemble silk.
A natural and synthetic polymer which at room temperature can be stretched.
_____ and ______ are examples of two elastomeric fibers.
Rubber and Spandex
This fiber is seldom used alone but no cover yarn is needed.
The most flame retardant fiber is also known as what?
This fiber picks up color from soil and wash and is a strictly thermoplastic fiber.
