Bleaching/reforming apparatus for fiber and fiber structure

Abstract

This invention provides a bleaching/reforming apparatus for a fiber and a fiber structure, comprising applying ultraviolet light and/or visible light from a lamp to a fiber or fiber structure impregnated with a liquid chemical of an oxidizing agent, a reducing agent or the like to bleach/reform the fiber and fiber structure, which apparatus can prevent soiling of the lamp and can enhance the efficiency of operation of the apparatus, and a light source unit for use in the apparatus. The apparatus comprises a light source unit (15) and a support member for detachably supporting the light source unit (15). The light source unit (15) comprises a lamp (153) for applying ultraviolet light and/or visible light, a frame (150) for housing the lamp (153), and a transparent plate (155) mounted onto the frame, for permitting light applied from the lamp (153) to be passed therethrough.

Description

technical field [0001] The present invention relates to a device for bleaching fibers and fibrous structures using an oxidant or a reducing agent, and light energy from a light source containing ultraviolet light and / or visible light, or to using a chemical solution and light energy from a light source containing ultraviolet light and / or visible light A device for modifying fibers and fibrous structures, especially a device capable of improving the working efficiency of the device. Background technique [0002] Bleaching of natural fibers such as cotton and wool, regenerated fibers such as viscose and high wet modulus viscose, and fiber structures is carried out by treating the coloring substances attached to the fibers and fiber structures with an oxidizing agent or reducing agent , cut off the conjugated π electron system related to color development. [0003] These steps are carried out by the following methods: the above-mentioned oxidizing agent or reducing agent is us...

AI Technical Summary

Problems solved by technology

[0009] However, compared with high-intensity light irradiation, if a low-intensity light using a light source such as Patent Document 2 is irradiated for a long time, there is a problem that the fibrous structure dries during light irradiation, and once it dries, even if Does not cause bleaching reaction even when irradiated with light, and does not improve whiteness

In the methods of Patent Document 2 and Patent Document 3, fluorescent lamps, ultraviolet lamps, etc. are used as light sources for radiating light energy. Chemical solution falling from fibers and fibrous structures, or dust attached to the air, thus reducing the illuminance

In addition, wet water or dust adheres to the electrodes of the lamp, which may cause malfunctions such as short circuits

Therefore, the lamp must be disassembled and cleaned quite frequently, and the device must be stopped during this period, so there is a problem that the operating efficiency of the device is low.
