Mercerisation is one of the most important processes of finishing cotton materials. The process consists of the treatment of cellulosic materials with concentrated solutions of caustic soda. Concentrated solution of caustic soda cause cinsiderable swelling of cotton fiber and allows soda to impregnate in the cross section of the warp & weft yarns. The impregnated yarn with caustic soda reflects light, hence it becomes brighter. Also, it increases its hygroscopicity, strength and improves dye affinity. The caustic soda concentration varies from 20% to 30%. Based on Buoyancy Principle. Perfect impregnation & stabilization followed by recuperator & wash tanks. Advantages of Mercerising Process; * Increase Dye Affinity. * Increased Luster. * Increased Tensile Strength. * Increased Dimensional stability of warp & weft yarn. * Elimination of immature or dead cotton. * Improved Handling effect. * Tailor made as per customer requirement. Acid Dosing arrangement, Big-Batching and Cylinder Dryer can be supplied additionally. The Machines are successfully running in India as well as Foreign Countries. The machines are available from 1500 mm to 3400 mm working width. More than 100 such "Thakore Exports" made machines are running all around the world.

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.

LIQUOR CIRCULATION A suitable pump with a filtering arrangement is provided in the Impregnator, which delivers the filtered caustic lye back into the Impregnator through a distribution system located between each Roller. On request, the machine can be equipped with a continuous auto cleaning filter. The stabiliser is compartmentalised and each compartment is provided with a Stainless Steel Pump which collects the hot wash liquor from the first washing compartment and pumps it to the last section of the stabiliser. This liquor is spread onto the fabric. Similarly from this last section, the liquor is collected, filtered and pumped to the preceding section. This continues till the first stabilising section, where the accumulated liquor is taken for recovery / disposal. The flow of liquor in the direction opposite to the movement of the fabric ensures excellent removal of caustic.

Lower incidence of re-dyeing ACCESSORIES WET-ON-WET The SWASTIK Merceriser can be provided with a NaOH preparation tank, chilling arrangement for the lye and a caustic recovery plant, if required. The machine can be supplied with acid neutralization system in the washer and a Dryer. WET-ON-WET MERCERISING Desize Impregnated Fabric can be Mercerised right away in our Wet-on-Wet Merceriser WWM-X. The number of Washing Compartments depends upon the quality of fabric and the production required. In cases where the fabric is Mercerised after Scouring, Wet-on-Wet mercerising is possible using only one Pre-wash Tank. Washing after mercerising remains standard. A heavy duty Squeeze Nip "Hi-Squeeze" with anti-deflection roller prior to the Impregnator enables uniform mercerising results. Impregnator for Wet-on-Wet Merceriser is equipped with an automatic Lye concentration controller. HOT MERCERISING Being a cost effective measure, the tendency to use Hot Mercerising is on the increase in recent years. Hot Caustic lye (at about 60°C) penetrates better and more evenly to the yarn core (of the fabrics). Swelling is better as compared to cold Mercerising which helps to improve the dimensional stability of fabrics. Hot Mercerising ensures even Dye penetration and imparts a softer handle and better appearance. Shorter impregnation time requirement reduces investment cost. For Hot Mercerising, the Impregnating section is equipped with an indirect steam heating system with a temperature controller to maintain uniform temperature. THE COLD IMPREGNATION PROCESS The traditional cold impregnation process imparts more lustre to the fibre than the hot impregnation system mainly due to the greater shrinkage and high tensions needed the re-stretch the fabric to the desired width. WIDTH STABILITY can be achieved by differential speed setting of the squeezing units, controlling the shrinkage or elongation of the fabric. This can be done manually or through automation, using PLC. COMBINED CHAIN AND CHAINLESS MERCERISER Besides Lustre, Depth of Colour and fabric feel, dimensional stability of the fabric is the most essential objective of mercerization today. These can be fulfilled with the Combined Chain and Chainless Merceriser. The length and width of the fabric can be controlled at will (within physical limits) using the combination of Chainless driven rollers with fully controlled drive and a stenter frame. The layout of the machine is shown in the layout drawing below. The intensive impregnating zone is followed by a reaction zone. Up to this point the fabric guidance is on the chainless princi ple. A part of the stabilizing zone is a stenter section using the pin chain princi ple. Final stabilization compartment is again chainless and is followed by the normal high-efficiency washing and neutralizing compartments. In the Stabilizing Zone, the uniformly applied lye is removed. Hot weak lye is first sprayed onto the fabric. Gradually reducing the shrinking force. In this condition the fabric can be stretched to the desired width with a comparatively less force. The possibility of stretching on the stenter ensures uniform shrinkage and even distance between warp yarn from the selvedge to the center. This is an important advantage of the Combined Chain and Chainless Merceriser if dyed woven or striped fabrics are to be processed. Increase in fabric width can also be achieved. The pin chain permits stretching by increasing the speed or shrinkage through fabric overfeed. AUTOMATION SWASTIK offers a fully automated machine with the most modern PLC control system which ensures optimum production. The level of automation can be designed for specific requirements of individual customers. Typical level of automation to access and control basic machine parameters, functions and displays using PLC with Graphic Colour Screen Display of various functions on a Touch Screen, can be as follows: • Drive synchronisation • Automatic Speed Control of machine through programmed Dwell time • Lye Dosing and concentration control as per set parameters • Liquor/Water Flow proportionate to fabric weight • Level control • Temperature control • Fabric Tension control by overfeeding in the Impregnator and Stabiliser • Acid Dosing with pH control. The system can be interconnected to a host computer or to other PLC for networking or data monitoring. Remote access of the control system is possible through use of a modem connected to the PLC. Automatic operation and control with necessary sensors provide extremely efficient operations. Lye concentration and dwell time control with perfect temperature regulation, ideal water flow regulation, level control etc. provide for excellent mercerising effect. A pH controller helps achieve neutral fabrics before drying and a Moisture Controller prevents unnecessary over-drying of the fabrics.
