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. 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






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






3. A yarn formed from inherently bulky fibers






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






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






6. A filament yarn consisting of a single fiber






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






8. A spun yarn process that eliminates roving and twisting






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






10. 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






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






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






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 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






15. Made of textured or crimped filament fibers






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






17. A bulk yarn made with little or no stretch






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






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






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






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






22. 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






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






24. 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






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






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






27. 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






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






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






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






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






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