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