Mercerising can be done at different stages during the pre-treatment process. This could be after De-sizing or after Scouring or after Bleaching. When done after desize-washing, it induces maximum lustre onto the fabric. However, contamination of lye can occur, which reduces life of the caustic lye. High degree of whiteness can be achieved if the bleaching process is done after mercerisation. Mercerisation after scouring and bleaching prevents contamination of caustic lye but effects the whiteness and absorbency. Mercerising can be done either on wet fabric with a lye concentration controller or on dry fabrics. Mercerising could be done with either cold lye or with hot caustic.                   CHAINLESS MERCERISING RANGE (MODEL - M)         Salient Features         1. Modular design, tailored to suit individual requirements. 2. Low width shrinkage with excellent dimensional stability. 3. Mercerised fabric has excellent lustre, high absorbency, better handle, uniform and repeatable finishing results. 4. Can be equipped with PLC controls for different functions such as fabric tension in Impregnator and Stabiliser, Shrinkage-Controller-cum Indicator etc. pH Indication / Control at the end of Washing, dwell time control by controlling speed flow control for walls & NaOH concentration control etc. 5. Lower Lye, Water and Steam Consumption. 6. Low maintenance. 7. Lower quantity of re-dyeing requirements.

Pneumatic padding mangle :   The main structure is fabricated out of heavy duty M.S. plate and incorporate with S.S. tank fitted with S.S. guide rolls and pneumatic pressure system.   Pre dryer and compensator :   The system consist of 20”/30”dia S.S. Cylinders of required width. Total 4 nos. dynamically balanced and gas heated system cylinders are mounted on heavy Chanel stracture frame with complete accessories. Guide roll provided for maximum contact of fabrics. The compensator unit ensuring proper speed synchronization of the stenter and mangle.       Bow &weft straightner :           The precise bow & weft straightner having two craved rubber sleeve expander rolls & two ebonite coated rolls are provided for fully straightning of the fabric.         The auto feeding device fitted at the entry of the stenter.                   Stenter :         The main stenter machine stands on C.I. casted legs which are coupled together by C.I. casted supports ensuring the vibration free movement of the machine rails are fitted on the structure for smooth & accurate running of clips. The clips are sg iron casted which gives long & sturdy lift and special desing keep the proper tension without damaging the fabrics. Clip openers are provided at both the entry and delivery end of the stenter. The stenter is driven by heavy duty sprockets. Fully motorized and complete system of width adjustment is fitted on the machine.                     Drying Chambers :         The mine structure fabricated out of M.S angles &covered with fiber glass wool pad insulated panels, which ensures &keep the proper temperature inside the chamber. The chamber covered complete length of the stenter.                   Selvedge drying & plaiting unit :         The main structure fabricated from heavy M.S. Pates and 3nos. stainless steel cylinders with heating system. Which gives the Quick Drying for the Selvedge of the Fabric.

Regulating valves and needle control valves.  In the pre dryer and selvedge dryer unit “v” type burners are fitted with required accessories.                   Drive :         The machine is running with D.C. Drive. Main drive motor of padding mangle and stenter are Tefc D.C motor. Reduction gear box is coupled with the main motor of stenter machine.                     Control :         Control panel for the machine will be fabricated by 16 Guage crc and finished with powder coating after defrosting procedure. Panel will be incorporated with the electric switch gear as per I.S STD. of required capacity. All A.C and D.C drive will control by separate auto manual circuit for different function of the machine. And Equipment. D.C. Drive will be supplied with dimmer jet Circuit & Dimmer Stat. Temperature controller for each chamber will beprovided with temperature compensating cable, Sensors, Digital, Indicator and controller.  The Complete Operation of the Machine will be operated and control at the push button type control panel board and Operating console fitted above the stenter machine                     Finishing :         Machine will be finised with red oxide, putty & primer paint and finally with 3 coats of industrial paint. Optionally finished with power coating process at extra cost.                   Important Note :         The length & width of the stenter machine, NO. OF Chamber, H.P of D.C/A.C motor varies according to buyer’s requirement.           Operating manual, wiring diagram of control panel and foundatio plan will be provided with the machine.         We reserves the right to Modify/Alter the Desing / Specification without prior notice.
