* Yarn Count Range / Draft Range / Lycra Dtex

Mar-03 3

* Relation between Elasticity and Draft

Mar-03 4

* Steaming• Generally, I dont recomment conditioning Cop or Cone • İf Necassary, ( your customer requested ) only CONE/Yarn package conditioning but we should do as below 1- Yarn PackageTube should has hole own surface 2- 2 cycle condition ; 5 min. 55 oC 20 min. 58 oC 3- Waiting time of Package at storehause should be minimum ( conditioned package should be use asap )

Soft winding

1 – If Filament production year less than 3 month you can finish complete otherwise dont finished it 2 - Humidity ( Keeping of flament at humidity room )

* Filament + Tube

Mar-03 9

* Filament - Production Year should be same - Same LOT should be on machine

Mar-03 10

* Filament - All package should be finish same time - to change lycra package alltogether will be easy for operators

• Balloon will not touch

surface of separators

• Traveller changing

period 1 week

be 25 max. • Traveller life cycle

must be max. 7 day

* Tarveller

- Traveller Type - Traveller Speed - Traveller Life cycle

• Winding end of tube

• Set the parameter on Terminal of Ring Frame Menu

• Otherwise yarn will break starting of doffing

Mar-03 16

• Should be Standart COAT on Machine

- According Fiber type , All Coat should be same on Machine

Mar-03 17

• Surface of Back and Front Coats must NOT be damage

• Peripdically should be control

Mar-03 18

• Should be non-damage APRON on Machine

• TOP and BOTTOM APRON must NOT be damage

• Peripdically should be control

Mar-03 19

Mar-03 20

It is necessary a right adjustment of the blower.•Other wise Roving will go out of roving stopper•Will be reason of Yarn fault•Will not clean filament package•Will not keep to clean sensor rollerNOT too manyNOT too narrow

• BLOWER Position

Mar-03 21

• Front Roller speed of Machine

• Actual measurment speed should be

same speed with AMSLER’s display

• Lycra Roller speed

• Checking SET values with measurements

FORMULA ; Front roller speed of machine / Lycra Roller speed = Lycra Draft

Mar-03 22

• OPERATOR CONTROL POINTS ON MACHİNE

• Filament / Lycra 1 - Winding 2 – Move on the Rollers 3 – Lycra should be inside of slot of Rollers 4 - Lapping on Rollers

Mar-03 23

• Lapping

Mar-03 24

• One of the roller of Blower should be metal or bearing •Metal roller should touch to rail for good grounding
