Control of Static in Textile Production
As fibres are manipulated during textile manufacturing processes – particularly in carding, beaming and feeding from creels – static is created which then causes these fibres to balloon or cling to surrounding surfaces and machinery. This causes breakages, and even operator shocks.
Control of Static in Textile Production - Select a problem:
The static charge on the sliver can be very high and must be controlled before the next process.
A long range, pulsed DC static eliminator such as the 3850 Ionstorm or the NEOS 20 can be positioned up to 500 mm from the apron and will not interfere with the process.
To maintain high machine speeds and to avoid breakages due to static charges, neutralise the charge by positioning a short range 3014 or 3024F Static Eliminator where the yarn is flat, such as after a comb or eyelets.
It is often necessary to neutralise each layer of yarn coming from a creel. A short range AC 1250-S Static Eliminator bar can be positioned just after eyelets, where the yarn position is fixed.
1255 bars can be joined together in series in a ‘ladder’ which covers several layers. Alternatively long range DC bars can be used to neutralise a group of yarns.
The moving delivery arm makes it difficult to locate a short range static eliminator. However, long range 24 V DC anti-static bars can be positioned approximately 500 mm from the centre position of the fabric.
Static charge is generated as the fabric is unwound and passes over the light table. This can cause adhesion to the table and also give shocks to people handling the inspected fabric.
The solution is to install a static eliminator at either end of the inspection table. Short range static eliminators such as the 3014 and 1250-S work efficiently in these positions.
The contact and separation processes in winding and unwinding generate high static charges. A long range static eliminator such as NEOS 20 is ideal to control the static in the reel.
