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 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






2. Made of textured or crimped filament fibers






3. 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






4. 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






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






6. 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






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






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






9. 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






10. 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






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






12. A filament yarn consisting of a single fiber






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






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






15. A spun yarn process that eliminates roving and twisting






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






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






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






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






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






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






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






23. 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






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






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






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. A yarn formed from inherently bulky fibers






28. A bulk yarn made with little or no stretch






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






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






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






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