According to one embodiment of the invention the cleaning composition or equipment being cleaned or both are heated to temperature, which is between above room temperature to below 130 ° C, preferably between 25 ° C to 130 ° C, more preferably between 45 ° C to 70 ° C, even more preferably between 50 ° C to 60 ° C. At the preferred temperature range, energy optimized cleaning performance is observed.
  • the equipment may paper, board or tissue making equipment, such as dryer fabric, press fabric, forming wire, rolls or other paper making machine surface.
  • the present cleaning composition is for cleaning soft surfaces of paper, board or tissue making equipment, such as dryer fabrics and/or felts, press fabrics and/or felts, as well as various wires, such as forming wires. It has been observed that the cleaning composition effectively removes adhesives and other corresponding contaminants from the surface of the felts, fabrics and wires, without damaging their surface.
  • Cleaning compositions were separately diluted with deionized water by filling wide jars with 80 g of deionized water and 20g of cleaning compositions with formulations as described in Table 1.
  • the jar was filed with lOOg deionized water. Samples were placed in separate jars, fully submerged, and left undisturbed for 1 minute. Samples were then taken out from the jar and placed in aluminum pan, and placed in the oven at 50-60°C under the hood for 30 minutes. The samples were then rinsed with water to remove any leftover cleaner.
  • Tergotometer was used to rinse. Tergotometer is an excellent device for batch cleaning of fabrics because it has constant counter flow action and temperature control. The tergotometer was set at 130°C. Large steel containers were filled with 600g of hot water. Samples were placed in separate containers. The rinse cycles were run for 15 minutes at 150 rpm, and the pH was recorded during the cycle.
  • each container was individually poured over a wire sieve and run under water briefly to help rinse any additional contaminants that the treatment had removed. All loose fabric fibers that were shed from the samples during the treatment and rinse cycles, were collected and accounted for in the "percent contaminant removal" calculations. The samples and corresponding lost fibers were placed back in the appropriate dishes and dried at 105°C. The samples were then allowed to cool down to room temperature in a desiccator and the mass of each sample, including the weight of loose fabric fibers that were shed from the samples during the treatment and rinse cycles, was recorded as "after treatment weight”. The change in weight or percentage weight loss between the uncleaned sample and clean, dried sample is attributed to contaminant removal or to percentage contaminant removed respectively. Percentage weight loss was calculated as, where "before treatment weight" is weight of uncleaned sample before treatment [084]
  • Fig. 1A original uncleaned sample
  • Fig. IB control sample after cleaning with deionized water
  • Fig 1C sample after cleaning with test composition 1
  • Fig ID sample after cleaning with test composition 2.
  • Table 4 shows percentage weight loss, calculated as described and pH before and after cleaning.
  • Table 2 shows, the compositions have low VOCs, high flash point and show no or very little foaming in water.
  • Table 3 shows that the compositions are stable at ranges of temperature and the components of the composition do not separate over prolonged periods of time.
  • Table 4 shows the compositions are efficient cleaners. pH of the cleaning solutions are close to neutral pH, before and after cleaning the dryer fabric samples with the cleaning compositions.
  • Test composition 1 Test composition 2
  • *pH before cleaning is the pH of the 20% composition (20 g of the composition, with formulation as described in table 1, in 80 g of water.)
  • ** pH after cleaning is the pH of the 600 ml water used in the rinse cycle.
