  • the liquid pressure within the airtight box 51 is made low pressure in gauge pressure being 1.2kg per square centimeter and the liquid pressure is maintained to about 103°C (the saturation temperature is about 104°C), since temperature of the mixed fluid of the washing liquid and the vapor ejected from the first slit 55 becomes about 99 - 100 °C, this is liquefied by the condensing apparatus 68 thereby the liquid temperature within the washing tank can be maintained to about 98° C not to produce boiling.

Therefore not only the cloth can be processed bulkily by the volume expansion due to evaporation of the washing liquid and the thermal set due to high temperature at 100° C or more, but also the washing efficiency of the cloth can be significantly improved by the mixed fluid of the washing liquid and the vapor.

  • the hot water is not boiled.
  • the pressure of the hot water falls in the fibers and as it is decreased to the evaporation pressure or less, the hot water is evaporated and expanded explosively. Consequently, the hot water flowing through gap between individual fibers is expanded explosively thereby the gap between fibers is widened explosively and a heat radiation set of the water temperature 100°C is produced (ironing phenomenon), and the cloth can be processed in soft and gentle feeling. Also by the explosive enlarging of the gap between fibers, the hot water can pass readily and the washing effect is improved.

  • water heated to 105° C is at the hot water state since 105° C is temperature less than the boiling point. If the hot water flows in the fibers, the pressure is lowered. Due to the boiling point lowering attendant on the pressure lowering, when 105° C becomes higher than the boiling point, the heat energy possessed by the hot water acts as evaporation heat and a part of the hot water is boiled and its volume is expanded explosively within the fiber.

  • tubular flexible member at the corner within the airtight box may be used also to interrupt the second slit for cloth passing, not only the closing of the second slit is secured by pushing force of the tubular elastic flexible member to the corner within the airtight box due to the pressure difference at the inside and the outside of the airtight box, but also the number of the first slits is increased thereby the washing capability can be improved corresponding to this increase.

  • two airtight boxes 51 as above described are fixed integrally back to back and mounted on upper side of a partition wall 72 provided between a pair of front and rear soft finishing tanks 70, 71 with thermal keeping means, and vertical portions before and after the cloth C roller-carried through a smoothing roller 73, a driven roller 74, a driven roller 75 and a smoothing roller 76 in sequence in the arrow F direction pass through each of the airtight boxes 51 respectively as above described, and the partition wall 72 is provided with upper and lower rubber packing plates 77 closing a cloth passing port 72a thereof, and an overflow tube 69 is connected to the soft finishing tank 71 so that the liquid level A2 of the softfin- ishing tank 71 becomes slightly lower than the liquid level A1 of the washing tank 70, and a surface condensing apparatus 68 including a number of cooling pipes 78 is mounted at a space between all slits 55 of the wait plate 51a of each airtight box and the inner wall of the washing tank opposed to this.
  • a lower outlet 70a of the soft finishing tank 70 is connected to an inlet port 79a of the centrifugal pump (volute pump) 79 without self sucking function arranged at lower side of the outlet 70a, and an exhaust port of the pump 79 is connected through a soft finishing liquid heater 80 and a line filter 81 in sequence to a soft finishing liquid supply port 57 to the airtight box at the side of the soft finishing tank 70.
  • Similar soft finishing liquid circulation circuit by a centrifugal pump is installed also between a lower end outlet 71 a of the soft finishing tank 71 and a soft finishing liquid supply port 57 to the airtight box, and the soft finishing liquid circulation circuit is provided with a soft finishing liquid heater and a line filter in sequence similarly to the case of the soft finishing tank 70, and the head difference between the liquid level of both soft finishing tanks 70, 71 and the inlet port of the pump is made amount sufficient to prevent the cavitation function of the pump.
  • any filter may be adopted as the line filter 81 as long as it can remove flocks in the soft finishing liquid, and the shown heater 80 is constituted in ejector form ejecting vapor under pressure from a tube 83 into a soft finishing liquid chamber 82, and the vapor amount under pressure ejected from the tube 83 and the rotational speed of the pump 79 are adjusted thereby the liquid pressure and the liquid temperature within the airtight box 51 can be always maintained as above described.
  • the liquid pressure within the airtight box 51 is made low pressure in gauge pressure being 1.2kg per square centimeter and the liquid pressure is maintained to about 103° C (the saturation temperature is about 104° C), since temperature of the mixed fluid of the soft finishing liquid and the vapor ejected from the first slit 55 becomes about 99 - 100 °C, this is liquefied by the condensing apparatus 68 thereby the liquid temperature within the soft finishing tank can be maintained to about 98° C not to produce boiling.
  • the liquid pressure within the airtight box can be made gauge pressure being 1.1 kg per square centimeter.
  • a soft finishing liquid of desire pressure flows as a cooling water through the cooling pipes 78 and a discharge liquid of each condensing apparatus 68 is supplied by a tube 84 to the pump inlet port 79a at the side of the corresponding soft finishing tank thereby the overflow liquid rate per each washing tank is compressed.
  • two airtight boxes 51, 51 are connected to inner walls of soft finishing tanks 85, 86 similar to the soft finishing tank of Fig. 19 so that wall plates with the first slits 55 are opposed to each other, and a condensing apparatus 87 is arranged between both airtight boxes 51,51 and the apparatus in Fig. 19 and the apparatus in Fig. 20 are connected in series, thereby the cloth C may pass through both apparatuses in sequence.
  • the pump inlet port at the side of each soft finishing tank is supplied with a half of the passing flow rate of the condensing apparatus 87 respectively.
  • parts designated by the same reference numerals as those in Fig. 19 show corresponding parts.
  • a soft finishing liquid having definite pressure higher than the outside atmospheric pressure and temperature slightly lower than the saturation temperature corresponding to the definite pressure passes in a carried cloth part grasped between the elastic flexible member and the top end surface of the projecting rib and is discharged from the first slit to the outside atmosphere thereby a part of the soft finishing liquid flowing through the grasped cloth part is evaporated. Therefore the cloth can be processed bulkily by the volume expansion due to evaporation of the soft finishing liquid and the thermal set due to high temperature at 100°C or more.
  • the hot water of the gauge pressure 0.5 kgf/cm 2 has volume about one I/kg.
  • the hot water is not boiled.
  • the pressure of the hotwater falls in the fibers and as it is decreased to the evaporation pressure or less, the hot water is evaporated and expanded explosively. Consequently, the hot water flowing through gap between individual fibers is expanded explosively thereby the gap between fibers is widened explosively and a heat radiation set of the water temperature 100° C is produced (ironing phenomenon), and the cloth can be processed in soft and gentle feeling.
  • the pump flow rate is made 100 I/minute and the gauge pressure is made 0.5 kgf/cm 2
  • water heated to 105° C is at the hot water state since 105° C is temperature less than the boiling point. If the hot water flows in the fibers, the pressure is lowered. Due to the boiling point lowering attendant on the pressure lowering, when 105° C becomes higher than the boiling point, the heat energy possessed by the hot water acts as evaporation heat and a part of the hot water is boiled and its volume is expanded explosively within the fiber.
  • the pump has the head length of 15m, the flow rate of 300 I/minute and the power of 1.5 kw, and it can produce large effect as above described in spite of the small power.
  • the elastic flexible member is constituted in tubular shape and a support arm with deformed crosssection inscribing with this at both ends on the diameter line in parallel to the top end surface of the projecting rib or in the vicinity of both ends is inserted in the elastic flexible member, not only variation of amount of the width B of the cloth can be dealt with, but also since the cloth can be pushed nearly equally against the top end surface of the projecting rib by the pressure difference at the inside and the outside of the airtight box, the cloth can be softened uniformly throughout the whole width.
  • tubular flexible member at the corner within the airtight box may be used also to interrupt the second slit for cloth passing, not only the closing of the second slit is secured by pushing force of the tubular elastic flexible member to the corner within the airtight box due to the pressure difference at the inside and the outside of the airtight box, but also the number of the first slits is increased thereby the softening capability can be improved corresponding to this increase.
  • the cloth washing apparatus according to the first invention as above described may be used as a cloth soft finishing apparatus freely.
