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.

Description

TECHNICAL FIELD [0001]The present invention relates to a method of washing a textile product, such as a woven fabric, which is to be carried out subsequent to another treatment such as dyeing, and a textile product treatment apparatus used therefore.BACKGROUND ART [0002]As an apparatus for carrying out a treatment such as dyeing for a textile product, for example, a liquid current treatment apparatus as illustrated in FIG. 4 is generally used. This apparatus has a retention part 2 for a woven fabric 1, and an annular treatment tank 4 connected between the retention part 2 and a transfer passage 3 for the woven fabric 1. The retention part 2 has a bottom portion provided with treating liquid suction portions 5 (three in this Figure), through which a treating liquid is sucked. The sucked treating liquid is heated under control to a given temperature (generally, a maximum temperature for it is set at a high temperature of 100° C. or higher) and returned to a treating liquid injection p...

AI Technical Summary

Benefits of technology

[0013]Specifically, according to the textile product washing method of the present invention, the high-temperature treating liquid used for the treatment is discharged while maintaining high temperature thereof, and during the discharge, it is heat exchanged with a washing water that is supplied into the treatment tank for washing. Thus, it is possible to remarkably increase the temperature in the washing treatment compared with the conventional method and thus produce an excellent washing effect. Therefore, the number of times of washing to be repeated subsequent to the discharge of the high-temperature washing water can be reduced as compared with the conventional method. Since the treating liquid is discharged while maintaining high temperature thereof, oligomer or dyeing residues or the like are kept dissolved in the treating liquid when discharged, and therefore a reduction cleaning treatment required in a conventional polyester deep dyeing or the like can be omitted. Thus, steam or a chemical agent used for increasing the temperature in the reduction cleaning treatment is not required, which contributes to the cost reduction. Since the amount of the oligomer or dyeing residue adhered to the inner wall of the treatment tank and thus remaining in the treatment tank is decreased, there is an advantage in that the workload in maintenance such as cleaning the treatment tank on regular basis is reduced. In addition, since the amount of the high-temperature treating liquid to be discharged is controlled to be equal to the amount of the washing water to be supplied, the amount of liquid circulating in the treatment tank can be kept constant even when the process changes from the dyeing or the like treatment to the washing treatment, and thus the textile product is prevented from being subjected to e

Problems solved by technology

However, the above washing method may pose problems of necessitating a long time washing, not realizing a smooth temperature gradient in cooling, causing wrinkles in the textile product, and thus deteriorating the quality of the fiber product.
