Fcsfa 230 Exam #2 (Manufactured Fibers)

Front 1

What are the two groups of manufactured fibers?

Back 1

1.) Synthetic
2.) Natural Base

Front 2

These fibers are meticulously engineered so they produce a better end product. They are man made not nature made.

Back 2

Manufactured Fibers

Front 3

What is the main advanatage to manufactured fibers?

Back 3

You can control the fiber and enhance its qualities.

Front 4

What is the 3-step fiber spinning process?

Back 4

1.) Prepare viscous syrupy dope
2.) Protrude dope through spinneret to form fiber
3.) Solidify fiber by coagulation, evaporation, or cooling

Front 5

What is the name of the object that you protrude dope through?

Back 5

The Spinneret

Front 6

The substance used to form solutions.

Back 6

Raw Materials

Front 7

Material from which a fiber is formed.

Back 7

Spinning Solution

Front 8

Forcing the dope through tiny holes in the spinneret.

Back 8

Extrusion

Front 9

This occurs when the polymer is dissolved by chemicals, spun into a bath, then coagulated.

Back 9

Wet Spinning

Front 10

When a polymer dissolved by a solvent is spun into warm air, and then the solvent evaporates.

Back 10

Dry Spinning

Front 11

When a polymer is metleted, spun into the air, and cooled.

Back 11

Melt Spinning

Front 12

Raw material dissolved in amine ocide, fiber spun into weak amine oxide solution, fiber precipitates out and solution is recycled.

Back 12

Solvent Spinning

Front 13

A fiber in its simplest form.

Back 13

A Parent Fiber

Front 14

Changes of the parent fiber relative to properties or chemical compositoin. Engineered for end use.

Modifications

Front 15

This is what controls the size of the spinneret opening....

Fiber Size

Front 16

What are two forms of manufactured fibers?

Back 16

1.) Cellulosic
2.) Protein

Front 17

If something is "oleophilic" what does that mean?

Back 17

It means that it has the ability to with stand moisture.

Front 18

Disposing of moisture away from the fabric.

Back 18

Wicking

Front 19

What was the first fully synthetic fiber and what was it used for?

Back 19

Front 20

This was developed to replace rubber (spandex).

Back 20

Lycra

Front 21

These came from plant materials and were then reformed.
