Rainbow has most modern Spinning Machines available in the industry. We have Blow Room/Automatic Bale Opener and Cards of "CROSROL Make". These machines are equipped with latest technology like PLC, PNP and NPN Sensor, MCB to give trouble free working. Entire system is automatically synchronized with the help of Photohelic. No manual operation is required at any stage. These are also connected to a centralized waste evacuation to remove the cotton waste generated during process. Cards are equipped with Long Term and Mid Term Auto-leveller to maintain the uniformity of Sliver and are having on line monitoring system called Card Management System (CMS). Length of Sliver, quality of Sliver in terms of CV% and other technical parameters can be adjusted on CMS as per the requirement of production.
We have installed "VOUK Make" Draw Frames which are equipped with Auto Levelers to ensure uniformity in sliver. These Machines are equipped with on line quality monitoring system. Any type of deterioration in sliver quality on account of CV, Draft Deviation, Count Deviation can be corrected with Spectrograph on the machine itself.
We have installed Auto Coros of "SCHLAFHORST and RIETER Make" with "AMSLER Make" Slub Attachment Devices. These are equipped with Coro Lab, line quality monitoring system and Yarn Cleaning System to produce uniform yarn. Length on the package can be selected on informator. All technical parameter can be adjusted on informator. Piecing and doffing of package is done by Robots Automatically.
We have installed Speed Frames of "TOYODA Make". These are having roving stop at desired length. The unique mechanism minimises roving irregularilities with the combination of microcomputer and CCD Electronic Eye Sensors.
We have also installed Ring Frames of "TOYODA Make" with Slub and Multi-count attachments to produce fancy yarn. Ring frames are equipped with E draft and Auto-doffing system.
We have installed Auto Cone Winders of "MURATA Make" with Air Splicer, single side and single deck type. These are also equipped with Electronic Yarn Clearer.
Rainbow has Ball Warpers of "McCoy ELLISON make" to get good quality of Rope and Ball by arrangement like Vacuum Reed.
We have "MORRISON Make" State-of-the-art technology Rope Dyeing Machine having 24 Rope Dyeing capacity with the following facilities :
- Individual arrangement for Indigo, sulphur black and other shades to provide best quality for washing and rubbing effect
- eparate arrangement for Sulphur/other shades topping and bottoming.
- Individual collections tanks for different styles i.e. different shades of dyes. For on line monitoring, we have following testing equipment in the Testing Laboratory :
- Spectrophotometer - for evaluating concentration of Indigo for Consistency of shade throughout the lot and lot to lot. • Veto meter - for controlling and measuring concentration of Sodium Hydro Sulphite.
- We have chemical laboratory to check concentration of purity of different chemicals used by titration method.
The Dye Room is fully air ventilated having sufficient amount of free oxygen for better air change for better oxidation by which we can get good colour effects.
We have installed Long Chain Beamers of "McCoy ELLISSON Make"and fully computerized Sizing Machine of "Ira L GRAFFIN Make". Creel Tension, Temperature of Cylinder, Stretch control and moisture control of sized yarn is totally controlled by Digital Computer. It is equipped with Saw Box having Vertical Nips along with Unique yarn path which eliminate hard size marks. Yarn exit path produces a perfect tangential path which reduces yarn hairiness. Vertical Nip maximize the effect of Wet Splitting and provides much greater operator access.
We have high speed fully automatic Air-jet Looms of "TOYODA and TSUDAKOMA Make" having following facilities :
- TAPO - Automatic pick finder.
- Electronic let-off and take-up motion with different settings for stop mark for any contrast fabric like Denim.
- ABS - Automatic Weft Brake System for better control on weft insertion and other damages related to weft are also controlled.
- Fully automatic centralized lubrication system.
We have Fabric Inspection Machines of "Kitamura Make" having computer inbuilt facilities for preparing cutting map to have optimum "A"/Premium quality of fabric as per the internationally accepted four point American System.
We have also installed Automatic Heat Shrinkage Machine to pack the Fabric Rolls.
For Cotton Testing, we have HVI 900 of "USTER" and Micro Dust Trash Analyser.
For Yarn Testing, we have UT4S and Tensokid of "USTER" and Wrap Reel and Beasley Balance of "INNOLAB"
For Fabric Testing, we have Bursting and Tear Strength Tester of "PRESTO", Crock Meter and Colour Cabinet of "INNOLAB" and Tumbler Washing and Drying Machine of "STAFAB"
We have installed Effluent Treatment Plant of "THERMAX Make"
- SAFF (Submerged Aeration Fixed Film Reactor) technology.
- Bio-Assay Test facility.
- Centrifuge Decanter for chemical and biological sludge handling.
- DMF (Dual Media Filter) and ACF (Activated Carbon Filter)
- Facility of both chemical and biological treatment.
