Subject : engineering
Instructions:
  • Answer 32 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • 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 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






2. Made of textured or crimped filament fibers






3. 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






4. A spun yarn process that eliminates roving and twisting






5. 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






6. A filament yarn consisting of a single fiber






7. A yarn unlike filaments of different deniers or generic types blended together






8. A slightly irregular bulky wool or wool- like yarn that has not been combed






9. A bulk yarn made with little or no stretch






10. Refers to a process of converting filament fibers to staple fibers by cutting or break stretching






11. A uniformly bulky filament yarn in which the bulk is added by crimping or texturizing the filament fibers






12. A yarn of filament fibers that have not been crimped or textured






13. An assemblage of fibers twisted or laid together so as to form a continuous strand that can be made into a textile fabric






14. A yarn with high degrees of potential elastic stretch and yarn curl






15. A yarn that has been processed to have greater covering power or apparent volume as compared with a conventional yarn






16. A slightly irregular spun yarn with short staple fibers and protruding fiber ends






17. An inexpensive yarn produced from extruded polymer film by extrusion or the split- fiber method






18. 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






19. An additional step in the production of smooth - fine - uniform spun yarns made of long- staple fibers






20. A yarn formed from inherently bulky fibers






21. A uniform spun yarn with long- staple fibers and few protruding fiber ends






22. 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






23. Refers to the process of twisting silk filaments into yarn or to the process of twisting and texturing synthetic- fiber- filament yarns






24. 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






25. An initial step in the production of spun yarns that loosens fibers from bale form and cleans and blends the fibers






26. 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






27. A process of producing a spun yarn by using carefully controlled - rapidly moving jets of air






28. Refers to a fabric of two or more generically different fiber types in which ply yarns consist of strands of each generic type






29. Refers to the process of adding bulk to yarns or modifying fabric surfaces






30. A very weak rope of fibers produced in intermediate steps in the production of spun yarns






31. A continuous strand of staple fibers held together by some mechanism






32. A fabric that consists of two or more generically different fiber types
