Description

Garment fabric sterilization method

Technical Field

The invention belongs to the technical field of textiles, and particularly relates to a garment fabric sterilization method.

Background

The fabric is seen everywhere in life, the fabric which is just manufactured may contain microorganisms such as viruses and bacteria which are harmful to human bodies, and if the microorganisms are not sterilized, the fabric is directly put on the market to be sold, so that the damage to consumers is possible, and in order to ensure that the consumers purchase and use the fabric more securely, the prior art adopts the disinfection after the fabric is manufactured.

Currently, the most common way in the disinfection process is to sterilize and disinfect by emitting ultraviolet rays through an ultraviolet germicidal lamp. The Chinese patent application with the application number of CN201310416749.X discloses a fabric sterilizing and drying machine, wherein an ultraviolet fluorescent tube is arranged in a box body. Realize the sterilization by ultraviolet. The principle of ultraviolet sterilization is as follows: the ultraviolet radiation destroys and changes the DNA (deoxyribonucleic acid) structure of the microorganism, so that the bacteria die immediately or cannot reproduce the offspring, thereby achieving the aim of sterilization. The existing ultraviolet germicidal lamp generally comprises a straight lamp tube, a filament, a cathode lead-out wire and a lamp holder, wherein the lamp holder is connected with an external power supply, mercury vapor and inert gas are generally filled in the straight lamp tube, electronic powder is coated on the filament, an electronic ballast is installed in the lamp holder, and the electronic ballast is connected with the filament through the cathode lead-out wire. The working process during light emitting is as follows: the lamp filament is heated by the electronic ballast to a certain temperature, the electronic powder on the lamp filament starts to emit electrons, and the electrons excite mercury atoms in the mercury vapor to emit ultraviolet rays.

However, the existing disinfection process using the ultraviolet germicidal lamp has certain defects: the ultraviolet lamp can only effectively disinfect one surface of the fabric facing the ultraviolet lamp, and the surface of the fabric facing away from the ultraviolet lamp cannot be effectively disinfected, so that the disinfection effect is poor.
