1. INTRODUCTION

   The purpose of this procedure is to define the general workmanship requirements for all textured yarns ring twisted, 2 for 1 twisted (except dye tube), and/or wound on the 300, 400, or 500 winder, on cones or paper tubes. These requirements are referenced by individual product specifications or procedures, which may also note exceptions and physical properties. Supply yarns are checked after texturing to provide added confidence that finished product meets specification. Uncontrolled copy.

2. SPECIFICATION

   1. Dirt/Grease– No soiling or grease spots allowed. It is acceptable if the spots can be cleaned off. For dirt on the outside surface – air strip yarn to waste. For dirt on the ends – clean with sprayer. If dirt does not come off, reject to off grade.
      
   2. Wound in waste – None allowed. Strip if possible to correct. Otherwise reject to rewind.
      
   3. Damaged/bumped – None allowed. Strip if possible to correct. Otherwise reject to rewind.
      
   4. F oil contamination – Dry or regular oil yarn must not be contaminated with F Oil when viewed under a packing table black light, unless very slight (not immediately visible). Strip to clean if possible. Otherwise reject to off-grade.
      
   5. Broken Filaments- 6 per end max allowable for cone packages. 8 per end max allowable for tube packages. 10 per end max allowed for large package.
      
   6. Texture color/appearance – No overly shiny or dull yarn allowed. Dull, bright, dye color, etc. per limit samples.
      
   7. Fluorescent Oil- If applicable, there needs to be even coverage when viewed under a blacklight.
      
   8. Crossed Ends- Nose end crosses are allowed, unless they appear matted or too numerous to count. Up to two 1 inch crosses on the tail end are allowed or crosses < ¼" from the tube are allowed. If crossed end cannot be corrected, reject to rewind.
      
   9. Slubs/Loops/Kinks – None allowed.
      
   10. Knots/Splices - Knots are permitted in coned yarn unless lot number indicates K for knotless. Knots are to be faced on the nose end with a 0.5 inch to 1.5 inch loop across the face of the cone so yarn won't catch on knot as it delivers. Knotless yarn may be air spliced unless otherwise indicated.
       
   11. Proper Wind- No patterns or bands. No high or falling off edges. No excessive hard/soft packages.
       
   12. Tube or Cone Defects- No crushed, nicked, cracked or cut tubes, especially on the nose end.
       
   13. Ridges/Grooves- No ridges or grooves > 1/8 inch high or deep.
       
   14. Texture - Yarn should bulk up when stretched several times and relaxed. No end should lack any bulk (raw end). 4 ply or more may have slight lean ends (end lacks full bulk), otherwise lean ends are not allowed. The tail is also checked.
       
   15. Air tacks (entanglement) – Minimum 12 tacks per foot for regular air. Low air should have some evidence of air tacks.
       
   16. Twist – For single ply yarns only, Z twist must rotate clockwise when allowed to relax and S twist rotates counter-clockwise.
       
   17. Proper ply - Check the number of ends if the yarn is two ply or more. Air strip the yarn to correct if possible. Also check the tail.
       
   18. Latching – Filaments or plies that separate when winding off package are not allowed.
       
   19. No tail - If there is no tail, then pack one large no tail package per layer. If excess no tail packages are found then reject to rewind. The minimum tail length is 1 wrap around the tube. If tail is too short, take a short length of yarn and tie it on to the tail. Parallel yarn small no tails are allowed.
       
   20. Multiple tails - If there are multiple tails, then correct if possible. Otherwise reject to rewind.
       
   21. Tube Clearance – from yarn roll to tail end of tube should be between 3/8" min. and 1"max. (5/8" nominal target for tubes.)
       
   22. Oversize or Small package - Check suspect packages with appropriate gauge or diameter tape. The diameter is determined by the setup and should be consistent within +/- 0.5 inches. Do not put excessive minimum size packages in one case.
       
   23. Packaging - Yarn packages are bagged with high density vented poly bags and packed into box so there is as little movement as possible. The bag is tucked into the nose end of tubes and the bottom open end of cones. Packages are not forced into the box. Tubes are packed nose end up. Cones may be packed alternating up and down. Box goes on conveyor to scale open with flaps taped down and inspector card GF007 placed in one of the tubes on top. The proper box is determined according to GSOP0090 Tare Weights Specification, the tube size, customer and lot number, or at Department Head direction. All boxes are 350 psi corrugated (or 51ECT) and may be reused or recycled. All box bottoms are taped with 72mm, clear acrylic tape and strapped shut with plastic strap.
       
   24. Weighing – Yarn is weighed per procedure COVSOP0077 as is with no allowance for moisture regain or finish. The case is weighed to determine gross weight. The net weight is calculated based on number of tubes and standard tare weight of all packaging materials.
       
   25. Case Labeling – Cases are labeled and individually numbered with computer transfer printed, stick on, three part label SHIPF014. In addition, each case has tube label SHIPF015 and shipping label SHIPF019. Labels have an important warning that if the Lot number on the container differs from previous shipments, keep separate unless your test prove this unnecessary.
       
   26. Color Labeling – If the yarn is colored, the color is written on the outside of the box with a marker. Different dye lots of the same color are kept separate. The dye lot and tube color is shown on the tube label.

       Guarantee/Disclaimers

   27. Sapona does not guarantee the dyeability of nylon products under 70 denier in multi-feed circular knit, warp knit or woven fabric applications. Sapona only guarantees that the yarns are properly textured. It is up to the customer to determine the suitability of these fine denier yarns in non-hosiery applications.
       

   28. Dupont 70/46 Tactel is not guaranteed for dyeability.
       
   29. Sapona does not guarantee mid-denier yarns dyed with rate sensitive acid dyes. Critical shades and shades with high wet fastness are likely to exhibit dye rate sensitivities. Rate sensitive dyes also include direct or neutral dyeing and premetallized classes.
       
   30. Yarn should be at least 3 days old before use and not more than 1 year old for critical applications.
