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

[0015]The textile product treatment apparatus of the present invention is achieved by merely adding a simple constitutional element to the conventional treatment apparatus, and therefore the above special washing method can be carried out efficiently at low cost.

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.

Also, since oligomer and the like, which have been dissolved at high temperature, are again precipitated, left in the treatment tank 4 and adhered thereto, a so-called tank washing is to be frequently carried out, which is very troublesome and thus poses a problem.
