Method of washing a textile product and textile product treatment apparatus used therefore

Abstract

There are provided a washing method using a treatment apparatus of the type, such as a liquid current treatment apparatus for treating a textile product by circulating a treating liquid that is capable of effectively washing a textile product in a shorter time, as well as a textile product treatment apparatus used therefore. A textile product 1 is loaded into a treatment tank 4 and a high-temperature treating liquid, which circulates inside and outside of the treatment tank 4 , is brought into contact with the textile product, thus treating the textile product, and then the textile product is washed with a washing water, in which subsequent to the treatment by the high-temperature treating liquid, the high-temperature treating liquid is gradually discharged from the treatment tank 4 while the washing water is gradually supplied into the treatment tank 4 , during which the discharged high-temperature treating liquid is heat exchanged with the supplied washing water, and the amount of the high-temperature treating liquid to be discharged is set to be equal to the amount of the washing water to be supplied so that the amount of liquid within the treatment tank 4 is kept constant.

1 . A textile product washing comprising loading a textile product into a treatment tank, bringing a high-temperature treating liquid, which circulates inside and outside of the treatment tank, into contact with the textile product, thus treating the textile product, and then washing the textile product with a washing water, wherein subsequent to the treatment by the high-temperature treating liquid, the high-temperature treating liquid is gradually discharged from the treatment tank while the washing water is gradually supplied into the treatment tank, during which the discharged high-temperature treating liquid is heat exchanged with the supplied washing water, and the amount of the high-temperature treating liquid to be discharged is set to be equal to the amount of the washing water to be supplied so that the amount of liquid within the treatment tank is kept constant. 
   
   
       2 . The textile product washing method according to  claim 1 , wherein at the time when the liquid within the treatment tank has been lowered to a given temperature range by the discharge of the high-temperature treating liquid and the supply of the washing water, the washing water is directly supplied into the treatment tank without being heat exchanged with the high-temperature treating liquid, thus washing the textile product. 
   
   
       3 . A textile product washing apparatus used for the textile washing method of  claim 1 , which comprises: a treatment tank into which a textile product is loaded so that the textile product is brought into contact with a treating liquid; a treating liquid circulation passage through which the treating liquid is taken out from the treatment tank to the outside and repeatedly supplied into the treatment tank via a circulation pump and a heat exchanger; a treating liquid discharge conduit that is connected on an intake side of the circulation pump to the treating liquid circulation passage so as to take out a part of the treating liquid from the treating tank and discharge the same to the outside; a washing water supply conduit that is connected on the intake side of the circulation pump and the downstream side of the connection portion of the treating liquid discharge conduit to the treating liquid circulation passage so as to supply a washing water into the treating liquid circulation passage; and a heat exchanger for heat exchanging the treating liquid passing through the treating liquid discharge conduit with the washing water passing through the washing water supply conduit, wherein the amount of the treating liquid to be discharged through the treating liquid discharge conduit and the amount of the washing water to be supplied through the washing water supply conduit are controlled to be equal to each other. 
   
   
       4 . A textile product washing apparatus used for the textile washing method of  claim 2 , which comprises: a treatment tank into which a textile product is loaded so that the textile product is brought into contact with a treating liquid; a treating liquid circulation passage through which the treating liquid is taken out from the treatment tank to the outside and repeatedly supplied into the treatment tank via a circulation pump and a heat exchanger; a treating liquid discharge conduit that is connected on an intake side of the circulation pump to the treating liquid circulation passage so as to take out a part of the treating liquid from the treating tank and discharge the same to the outside; a washing water supply conduit that is connected on the intake side of the circulation pump and the downstream side of the connection portion of the treating liquid discharge conduit to the treating liquid circulation passage so as to supply a washing water into the treating liquid circulation passage; and a heat exchanger for heat exchanging the treating liquid passing through the treating liquid discharge conduit with the washing water passing through the washing water supply conduit, wherein the amount of the treating liquid to be discharged through the treating liquid discharge conduit and the amount of the washing water to be supplied through the washing water supply conduit are controlled to be equal to each other.
