Ceramic components for themelt spinning processDifferent surfaces for customers’ applications:The REM pictures below show the different types of ceramicsurfaces as used for different kinds of technical processes.Surface: As fired for POY semidull and bright, e.g. dtex 300 (167) f 32New dimensions with TRIBOFIL ® and TRIBOSOFT ®TRIBOFIL ® is our surface finish for yarn guide elements forlow-tension applications and for the processing of commonlyproduced synthetic yarns without any yarn damage. This materialhas been proven worldwide and is highly rated by thecircle of expertise in the industry.Surface: Polished for wire and glass fibreTRIBOSOFT ® is an established advanced surface treatmentused for processes at low yarn tensions without any yarndamage, having long life cycles on both special yarns and rawmaterials containing aggressive additives such as spun-dyedyarns (spun-dyed black), CS and bioactive yarns.TRIBOFIL ® and TRIBOSOFT ® are only available from CeramTecand provides you with:Surface: TRIBOFIL ® for FOY semidull, bright and micro-filaments, e.g. dtex 67 f128, POY micro-filaments, e.g. dtex 130 (76) f 144iMelt spinning components• Lowest possible yarn break rates• Highest yarn cleanliness• Low yarn tension• Excellent package build-up• High quality and cost efficiencySurface: TRIBOSOFT ® for spun-dyed (spun-dyed black) and special raw materials,e.g. CS, full dullSurface R avalue [µ] CoefficientPOY 100D/200f of fictionTRIBOFIL ® 1.1 0.3TRIBOSOFT ® < 0.3 0.4Polished < 0.3 0.8As fired 0.75 0.4

Ceramic discs for thetexturing processCeragol working discsAdditional productsThe benchmark for the texturing processEver since the 1970s, when friction texturing using threespindle texturing units made its breakthrough, solid ceramicfriction discs made by CeramTec have demonstrated their superiorityin this process. They are extremely effective in thecontinuous operation of friction texturing. CeramTec solidceramic friction discs have many decisive advantages whencompared with other disc materials:Working discsiCeramic friction discsGuide discs• Long service life, due to the material’s high wear andtear and corrosion resistance• Even and constant yarn quality from position toposition, due to the consistent disc finish• No detrimental effect from spinning preparations, i.e.free choice of finishing agents• No damage to friction disc in the event of runningyarn at spindle-stop• Considerable flexibility in speed and titre ranges, alsosuccessfully used in microfilament production• Easy start-up of disc units, particularly at high yarnspeeds, when yarn tends to jump out of thedisc groove• Universal cleaning possibilities: with acids, alkalinesolutions, burning at high temperatures or in anultrasonic bath• Extremely low build-up of rubbing powder, especiallywhen using Cerasoft ® G• Ceragol – innovative special grooved structure makesCeragol ideal for texturing spundyed filament yarnsmade of polyester, polyamide and all other types ofraw materials in texturingKnife discs

Navels for open-end spinningAdvanced ceramics improve processing stabilityThe characteristics of technical ceramics made by CeramTec,especially hardness, give high processing stability to thespinning operation. CeramTec's advanced ceramics haverepeatedly replaced metals in such applications. The chartdemonstrates the hardness of various ceramics comparedwith various grades of steel.Comparison of hardness of hardened metalsand advanced ceramicsWorldwide approved navels in various designsTried and tested millions of times, navels from CeramTecperform key functions in the spinning boxes of all wellknownrotor spinning machines, such as Rieter Ingolstadt or SpindelfabrikSuessen. CeramTec Navels have a substantial influenceon spinning stability, hairiness and twist as well as on theessential nominal specifications of open-end spinning.iNavels at a glanceThe CeramTec navel profile is characterisedas follows:• Good wear and corrosion resistance• Different variations of material:- Ultrapure 99.7% Al 2O 3ceramics• Special navels designs:- straight notched versions- spiral versions- crescent-shaped notch versions- with built-in cross-shaped exit hole- various geometries for customer requirements• Surface finish:- high-gloss polish- various grades for different applications• Precision manufacturingShoes and traverse guidesCeramTec also leads the world in supplyingrotor spinning machines with:• Shoe-type and slotted traverse guides• Bent navels• Exit inserts with cross-shaped webs

Ceramic cuttersA wide range of technical argumentsiCutters at a glance• Faster cutting rates• Consistently good cutting quality, e.g. improvedstrength of spliced connections• No corrosion• Smooth running• Extended maintenance intervals• Universal cleaning possibilities using acids,alkaline solutions and organic solventsLong lasting cutting with advanced ceramicsLong lifetime, consistently defined cuts, no fiber-squeezingor backlashing of fiber within the cutting angle zone ofthe shears – some of the many benefits of using advancedceramics cutting blades in the production process. For cuttingpurposes CeramTec has developed the advanced material3Y-TZP – a special zirconia ceramic. It stands out from othermaterials with its extremely high cutting edge strength andvery good bending strength and toughness.The use of 3Y-TZP cutting blades improves efficiency in cuttingtextile threads, and thus increases profitability. The numberof applications in the textile industry ranges from splicer,suction tube and residual tread shears for winding machinesto final thread and side shears for looms. In many machinesand applications, cutting blades made of 3Y-TZP are the materialof choice and have set a standard.The range of applications for ceramic cutters is expandingrapidly. They are now used for medical purposes, and also inthe food and automotive industry.Fracture toughness and bending strengthA comparison of fracture toughness and ultimatebendingstrength between aluminium oxide ceramicand zirconium oxide 3Y-TZPAI 2O 3ZrO 2-Y 2O 33Y-TZPAI 2O 3ZrO 2-Y 2O 33Y-TZPFracture toughnessUltimate bendingstrengthCircular blades
