The housing member 200 is made of a metal material that has a certain strength and is resistant to corrosion, is coupled to and fixed to the frame member 100, and uses a synthetic resin net containing hemp hull yarns to be bleached, and a needle containing a bleaching agent. It is immersed in water to perform decolorization through rotational agitation, and includes an immersion housing 210, a housing cover 220, and a perforated plate 230.

For the synthetic resin net, a cloth laundry net, which is a commercially available material such as polyester, is generally used. There is no need to place any special restrictions on the size of the mesh, and the overall size of the synthetic resin net is transportable during agitation. It is preferable to use a rectangular net having a size of about 30 to 60 centimeters in width and length or a circular net having a diameter of about 30 to 60 centimeters in consideration of convenience and input conditions of even soaking water into the hemp hull yarn. The synthetic resin net serves to physically protect the injected hemp shell yarn in the decolorization process by rotational agitation using the hemp shell decolorization device for hemp yarn according to the present invention, as well as to prevent excessive clumping.

In addition, the amount of hemp shell yarn injected into the synthetic resin net is approximately 0.5 to 2 kilograms per net in consideration of the convenience of transportation during agitation work, the input conditions of the impregnation water selected for the hemp shell yarn, and the appropriate conditions of rotational agitation. It is preferable to inject, and in this embodiment, injecting 1 kg of unfolded hemp hull yarn per net is suggested as an optimal embodiment.

The immersion housing 210 is provided in a semi-cylindrical shape lying in the horizontal direction, and provides a space in which the bleaching process is performed by accommodating the immersion water to which a decolorant or the like can be added and the synthetic resin net containing the yarn of the hemp husk.
