Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A continuous strand of staple fibers held together by some mechanism
combed yarn
tape yarn
combing
spun yarn
2. An inexpensive yarn produced from extruded polymer film by extrusion or the split- fiber method
tape yarn
yarn
textured/bulked yarn
bulk yarn
3. Refers to a process of converting filament fibers to staple fibers by cutting or break stretching
tow to top system
woolen yarn
mixture
textured/bulked yarn
4. A smooth - straight - and uniform wool or wool- like yarn that has been processed to remove short fibers and to make the remaining fibers more parallel
combination
worsted yarn
spun yarn
blend
5. An assemblage of fibers twisted or laid together so as to form a continuous strand that can be made into a textile fabric
carded yarn
texturing
yarn
sliver
6. A slightly irregular bulky wool or wool- like yarn that has not been combed
woolen yarn
spun yarn
roving
throwing
7. An additional step in the production of smooth - fine - uniform spun yarns made of long- staple fibers
carded yarn
combing
high bulk yarn
texturing
8. A process of producing a spun yarn by using carefully controlled - rapidly moving jets of air
sliver
roving
air- jet spinning
woolen yarn
9. A very weak rope of fibers produced in intermediate steps in the production of spun yarns
sliver
smooth filament yarn
bulk yarn
monofilament yarn
10. Refers to the process of twisting silk filaments into yarn or to the process of twisting and texturing synthetic- fiber- filament yarns
bulky yarn
woolen yarn
throwing
combing
11. A fabric that consists of two or more generically different fiber types
blend
worsted yarn
roving
high bulk yarn
12. Refers to the process of producing a yarn from staple fibers - it also refers to the production of a fiber by extruding a solution through tiny holes in a spinneret
bulk continuous filament yarn
spinning
open end rotor spinning
tow to yarn system
13. A fiber blend - yarns of one generic type are present in one fabric area and yarns of another generic type are present in another fabric area
bulky yarn
tape yarn
mixture
spinning
14. Made of textured or crimped filament fibers
yarn
air- jet spinning
bulk continuous filament yarn
monofilament yarn
15. A yarn of filament fibers that have not been crimped or textured
tape yarn
combed yarn
blended filament yarn
smooth filament yarn
16. A yarn formed from inherently bulky fibers
carded yarn
mixture
air- jet spinning
bulky yarn
17. A yarn unlike filaments of different deniers or generic types blended together
blended filament yarn
carding
spun yarn
texturing
18. A slightly irregular spun yarn with short staple fibers and protruding fiber ends
combing
carding
texturing
carded yarn
19. A yarn with high degrees of potential elastic stretch and yarn curl
sliver
carded yarn
stretch yarn
high bulk yarn
20. A yarn that has been processed to have greater covering power or apparent volume as compared with a conventional yarn
roving
smooth filament yarn
bulk yarn
textured/bulked yarn
21. An initial step in the production of spun yarns that loosens fibers from bale form and cleans and blends the fibers
opening
bulk yarn
tape yarn
texturing
22. A uniform spun yarn with long- staple fibers and few protruding fiber ends
bulky yarn
throwing
combing
combed yarn
23. A bulk yarn made with little or no stretch
high bulk yarn
carding
bulk continuous filament yarn
combed yarn
24. Refers to the process of adding bulk to yarns or modifying fabric surfaces
texturing
smooth filament yarn
combed yarn
ring/conventional spinning
25. A process for producing spun yarns; a series of operations removes fibers from a bale - removes debris - makes the fibers parallel - draws them into a fine strand - and adds twists to hold them together
carded yarn
bulk yarn
bulky yarn
ring/conventional spinning
26. Refers to a fabric of two or more generically different fiber types in which ply yarns consist of strands of each generic type
combed yarn
woolen yarn
sliver
combination
27. A filament yarn consisting of a single fiber
opening
texturing
stretch yarn
monofilament yarn
28. A step in the production of some spun yarns - the drawn sliver is reduced in size - fibers are made more parallel - and a small amount of twist is inserted
tape yarn
carded yarn
monofilament yarn
roving
29. Refers to a process of converting filament fibers to staple fibers by break stretching - drawing the fibers - adding twist - and winding the yarn on a bobbin
