Yarn Processing

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






3. 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






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






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






6. 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






7. 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






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






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






10. A spun yarn process that eliminates roving and twisting






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






12. Made of textured or crimped filament fibers






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






14. 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






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






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






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






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






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






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






21. A yarn formed from inherently bulky fibers






22. 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






23. A bulk yarn made with little or no stretch






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






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






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






27. 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






28. A filament yarn consisting of a single fiber






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






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






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






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