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. Refers to the process of twisting silk filaments into yarn or to the process of twisting and texturing synthetic- fiber- filament yarns
tow to yarn system
throwing
texturing
ring/conventional spinning
2. A filament yarn consisting of a single fiber
monofilament yarn
ring/conventional spinning
worsted yarn
spinning
3. A slightly irregular spun yarn with short staple fibers and protruding fiber ends
roving
stretch yarn
high bulk yarn
carded yarn
4. A yarn that has been processed to have greater covering power or apparent volume as compared with a conventional yarn
bulk yarn
high bulk yarn
worsted yarn
roving
5. A bulk yarn made with little or no stretch
mixture
high bulk yarn
throwing
combed yarn
6. Refers to the process of adding bulk to yarns or modifying fabric surfaces
sliver
tow to top system
texturing
combing
7. A spun yarn process that eliminates roving and twisting
stretch yarn
blend
bulk continuous filament yarn
open end rotor spinning
8. A uniformly bulky filament yarn in which the bulk is added by crimping or texturizing the filament fibers
tow to top system
ring/conventional spinning
throwing
textured/bulked yarn
9. 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
stretch yarn
yarn
combed yarn
worsted yarn
10. A yarn unlike filaments of different deniers or generic types blended together
tow to top system
blended filament yarn
worsted yarn
spinning
11. Refers to a fabric of two or more generically different fiber types in which ply yarns consist of strands of each generic type
yarn
bulky yarn
smooth filament yarn
combination
12. 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
tow to yarn system
worsted yarn
carded yarn
blended filament yarn
13. One step in yarn spinning - staple fibers are drawn together in a somewhat parallel arrangement to form a very weak rope of fibers called carded sliver
spun yarn
carding
bulk yarn
combination
14. A yarn with high degrees of potential elastic stretch and yarn curl
combination
opening
stretch yarn
bulk continuous filament yarn
15. A very weak rope of fibers produced in intermediate steps in the production of spun yarns
textured/bulked yarn
monofilament yarn
carding
sliver
16. A slightly irregular bulky wool or wool- like yarn that has not been combed
tape yarn
woolen yarn
roving
carding
17. A uniform spun yarn with long- staple fibers and few protruding fiber ends
sliver
combed yarn
throwing
stretch yarn
18. 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
bulk continuous filament yarn
worsted yarn
bulky yarn
ring/conventional spinning
19. An inexpensive yarn produced from extruded polymer film by extrusion or the split- fiber method
bulk continuous filament yarn
texturing
tape yarn
smooth filament yarn
20. 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
worsted yarn
roving
air- jet spinning
sliver
21. Refers to a process of converting filament fibers to staple fibers by cutting or break stretching
high bulk yarn
opening
tow to top system
throwing
22. 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
blended filament yarn
high bulk yarn
monofilament yarn
mixture
23. A yarn formed from inherently bulky fibers
throwing
texturing
open end rotor spinning
bulky yarn
24. A continuous strand of staple fibers held together by some mechanism
spinning
spun yarn
ring/conventional spinning
tow to yarn system
25. 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
spinning
open end rotor spinning
yarn
air- jet spinning
26. A fabric that consists of two or more generically different fiber types
woolen yarn
tape yarn
stretch yarn
blend
27. An initial step in the production of spun yarns that loosens fibers from bale form and cleans and blends the fibers
textured/bulked yarn
mixture
ring/conventional spinning
opening
28. A process of producing a spun yarn by using carefully controlled - rapidly moving jets of air
texturing
combed yarn
air- jet spinning
ring/conventional spinning
29. An assemblage of fibers twisted or laid together so as to form a continuous strand that can be made into a textile fabric
yarn
tape yarn
carded yarn
throwing
30. Made of textured or crimped filament fibers
bulk continuous filament yarn
smooth filament yarn
air- jet spinning
bulk yarn
31. A yarn of filament fibers that have not been crimped or textured
roving
carded yarn
smooth filament yarn
mixture
32. An additional step in the production of smooth - fine - uniform spun yarns made of long- staple fibers
spun yarn
combing
blend
mixture
