Question regarding the product life of the vulking rubber belt. 

• "What is the product life?"
  

It's very difficult to answer this question, thus we dare to justify our answer.

Rubber belts often suffer damage caused by accidents, improper operation and/or maintenance, cloth width considerations, or are taken out of service simply because they have been reduced in thickness to some arbitrary minimum useful thickness. Rubber belts can continue to be kept in use regardless of thickness, as long as they continue to provide required pre-shrinking capability.

Other major factors are: types of fabrics being processed, types of finishes applied to the cloth, machine operator skill, quality of water used to cool the rubber belts, excessive heated cylinder surface temperature, excessive compression (squeeze) of the rubber belt, improper tension applied to the rubber belt, poor condition or adjustment of rubber belt cooling water sprays or felt doctor, incorrect adjustment of belt lateral limit rollers, insufficient frequency of belt re-surfacing (grinding), prolonged and/or frequent stoppage of the shrinking machine while heated cylinders are at operating temperature.

As is evident from the above, there are very many factors, aside from the actual rubber belt quality, which may exercise a significant impact on belt longevity. To suggest a specific useful life for any rubber belt would be less than honest.

We have the Technical know-how to assist customers and train their personnel to take advantage of the unequalled quality of Vulking Rubber Belts.

Our efforts are towards gaining technical expertise by persistence, tenacity, innovation, earning product loyalty by consistent supply, reliable service, maintenance, committed dedication and by fulfilling the precise demands of the textile industry. quality control that strives for a perfect production process, resulting in flawless products ever

Ever endeavour for product performance, we today are able to assure a production of nearly 11 to 14 million meters of sanforized fabric subject to excellent conditions maintaining the Preshrink Rubber Belts.

• How to Improve Life of Rubber Belt?

1. Select proper thickness Belt for light weight and heavy weight fabrics. Light weight fabrics with low shrinkage : Thickness 51-55 mm for comfit process. Heavy weight fabrics with high shrinkage : Thickness 65-70 mm
2. Select proper width of Belt width should be 150-200 mm wider than cloth to be processed.
3. Use proper surface temperature on the Belt as needed for each type of cloth to be processed. Operative temperature on Belt surface is as low as 105 degree celsius and maximum 140 degree celsius, A correct fabric preparation and proper adjustment of moisture content of the cloth entering the surface of the Belt correct Rubber compression and proper shrinkage machine speed will permit even the most difficult fabric to be processed with optimum results at the minimum required heated cylinder temperature.
4. Use the water on external surface of the Belt to keep surface temperature down. The lower end of the Belt should be pass through water tray for effective lowering Belt temperature. Also use of lubricating water supply on the Belt is squeezed at the pressure roll, the Rubber Belt must elongate and slip in order to pass through reduced nip of roller and hence inner surface of Belt must slip against pressure rollers. Use of lubricating water spray will facilitate easy squeezing of Belt  will minimize inner surface at this point will considerably restrict Belt elongation, which will proportionately reduce the capacity of the Belt to pre-shrink the cloth in the wrap (length) direction.
5. It is not good practice to delay Belt surface grinding. Grinding should be done periodically after checking hardness of the Belt at its side and center. If hardness differs by 3 to 5 degree shore A a proper grinding cut should be done. Preferably after running 4,00,000 meter production, surface grinding of Belt gives the Belt longer life.
6. Do not neglect even small crack and  grinding is recommended to prevent further damage to the Belt.
7. Shrinkage machine should be cool enough before stopping the operation. Stopping machine in hot condition will reduce life of Belt drastically.
8. Cleaning the Belt after fabrics shrinkage operation will extend life of the  Belt. After stopping water spray, spray it with mild detergent, wipe the surface of Belt with soft brush and again start cooling water sprays to rinse all soap detergent from Belt surface. Also clean the heating drum with soft brush wash to remove any surface deposition on the drum.
9. Do not use any solvent or petrol / diesel to clean Rubber Belt or metal cylinder drum.
10. Avoid excessive compression and improper tension applied to the rubber belt.
