Description

Yellow tiger remover for water jet looms

The present invention relates to a yellow rust remover for water jet looms, and more particularly, to contain a non-oxidizing fungicide as an active ingredient of the yellow rust remover produced in the water jet loom, as well as to obtain excellent sterilization and sterilization effect against yellow tiger And it relates to a yellow tiger remover for water jet looms to solve the problem of loom corrosion by the disinfectant.

Since the entraining device of the water jet loom is made by water, the loom is always submerged in water. Therefore, the life of fabrics and looms is closely related to water quality. The water sprayed in the sprayed state wets the slope as well as the rear of the heald, and at this time, the glue, emulsion, etc. attached to the inclined are eluted and buried in the heald. It is possible to breed microorganisms by using organic matters, emulsions, antistatic agents, etc., which are applied to healds, bodies and plastic covers of water jet looms, and yellow lumps of yellow microbes buried in water jet looms are called 'yellow tiger'. The yellow rust generated by the water jet loom causes problems such as poor fabric quality due to stains and molds, low weaving rate, loom corrosion due to rot of yellow rust, personal hygiene and environmental defects.

In the conventional method for removing such yellow rust, a method of sterilizing industrial water using an oxidizing fungicide has been widely applied. In general, oxidizing fungicides are economical, but they are highly corrosive and have low sustainability. In particular, oxidizing fungicides react with the polysaccharides surrounding the microorganisms before directly reacting with the microorganisms constituting the biofilm. It has a downside.

As an oxidizing fungicide, NaOCl is easily decomposed by air, light or heat, and its activity is greatly reduced during distribution. When applied to a water jet weaving machine, NaOCl is decomposed at the same time as spraying and dispersed in the air. In addition, since the oxidizing fungicide has the property of reducing the sterilizing effect at high pH (80% reduction of the sterilizing power at pH 8), the sterilizing effect is not sufficient, but it causes the lower corrosion by the slime and the fine nozzle hole etc. by the scale. It has been pointed out that problems such as clogging can be prevented and weaving can occur due to chlorine ions generated from oxidizing fungicides such as NaOCl.

Therefore, the yellow rust remover for water jet looms must selectively kill microorganisms, not corrosive, and require fastness and durability.

In the present invention, to overcome the problems appearing in the use of the conventional oxidizing fungicides and to obtain a yellow rust remover that can more efficiently suppress or remove the yellow rust generated in the water jet loom. As a result, non-oxidizing fungicides such as 3-isothiazolone, which are effective for the sterilization of microorganisms, the suppression and sterilization of slime-forming bacteria that cause slime, and the sterilization of anaerobic microorganisms that cause lower erosion, can be used as an active ingredient. The present invention was completed by knowing that the problem of sterilization and removal of the loom as well as the problem of loom corrosion can be solved at the same time.

Therefore, the present invention selects an appropriate composition ratio in which a synergistic effect of the fast-acting compound and the sustaining compound is expected, and specifically removes the biofilm by reacting specifically to the causative agent of yellow drop formed on the water jet loom, The purpose of the present invention is to provide a yellow water drop remover for a suitable water jet loom, which prevents the formation of a biofilm by removing microorganisms while remaining on the surface of the loom.

The present invention is characterized in that the yellow rust free remover for water jet loom containing a fungicide as an active ingredient, wherein the non-oxidizing fungicide containing 3-isothiazolone compound represented by the following formula (1) is contained as the active ingredient do.

The present invention relates to a yellow rust remover that is useful for sterilization and removal of microbial slime (yellow rust) generated by water jet looms by including non-oxidizing fungicides such as 3-isothiazolone compounds.

In general, the surface of the water jet loom is exposed to a large amount of organic matter, including a lake, etc., and a biofilm is formed by attaching microorganisms (bacteria, mold) present in water, lake, air, and the like. As the microorganisms capable of secreting some polysaccharides are propagated to the microbial membrane attached to the loom surface, the polysaccharides are secreted. As a result, the surrounding microorganisms and inorganic substances are attached and the biofilm becomes large. Early biofilms consist of a group of aerobic microorganisms, but as time goes by, the interior of the biofilm is gradually changed to anaerobic conditions, whereby anaerobic microorganisms such as sulfate-reducing bacteria (SRB) can proliferate. PH reduction by metabolites of microorganisms constituting the biofilm and hydrogen sulfide gas by anaerobic microorganisms are generated, ultimately causing corrosion of the loom.

The 3-isothiazolone compound to be used as an active ingredient in the yellow rust removing agent according to the present invention is a non-oxidizing bactericidal agent, and there is no fear of corrosive jet loom, and it will selectively kill microorganisms (bacteria, mold) forming yellow rust. It also has an excellent effect on SRB bacteria, which are fundamentally responsible for microbial corrosion (MIC).

The 3-isothiazolone compound which can be used in the present invention is a single or a mixture of two or more represented by the formula (1). Among them, a mixture of 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one is preferably used.

In addition, the yellow rust remover according to the present invention can be used as an active ingredient by mixing another non-oxidizing fungicide to the 3-isothiazolone compound represented by the formula (1). Non-oxidizing fungicides that can be used with the 3-isothiazolone compound represented by Formula 1 include, for example, 2,2-dibromo-3-nitrilopropionamide, 1,2-benzisothiazolin-3-one , 2,2-dithio-bis (pyridine-1-oxide), bis (dimethylthiocarbamoyl) disulfide, 2,2-dibromo-2-nitroethanol, 3-iodo-propynylbutylcarbamate, N-diethyl-N'-phenyl- (N "-fluorodichloromethylthio) -sulfamide, 2,3,5,6-tetrachloro-4- (methylsulfonyl) pyridine, 2- (thiocyano Methylthio) -benzthiazole, benzimidazolecarbamic acid methyl ester, bis- (1-hydroxy-2 (1H) -pyridineethionate-O, S) zinc, o-phenylphenol, 2,2- Dihydroxy-5,5'-dichlorodiphenylmethane, N- (fluorodichloromethylthio) phthalimide, glutaraldehyde, quaternary ammonium salt, 3,5-dimethyl-tetrahydro-1,3,5- 2H-thiadiazine-2-thiono, methylenebisthiosi To use the at least one selected from carbonate and bromo nopol.

When the 3-isothiazolone compound represented by the formula (1) and the non-oxidizing bactericide exemplified above are mixed and used as the active ingredient of the yellow rust remover, the mixing ratio is preferably maintained in the weight ratio range of 1:30 to 50: 1. Do. If the mixing ratio is out of the above range, there is a problem that the synergy effect due to the mixed use is lowered and the overall efficiency is lowered, which is not preferable.

In addition to the active ingredient as described above, the yellow rust removing agent according to the present invention may be used by mixing additives such as ordinary extenders, stabilizers according to the preference.

In addition, there is no particular limitation on the final formulation of the yellow rust remover, powder, granules, tablets, hydrating agents, emulsions, etc. can be selected and used as needed, usually an effective amount of a non-oxidizing fungicide is directly used in industrial water.

In addition, in applying the yellow antirust agent according to the present invention to the water of the water jet loom, it is preferable to maintain the non-oxidizing fungicide 0.5 to 150 ppm, the content of the non-oxidizing fungicide in the water of the water jet loom is less than the above range If the back side of the present invention has a negligible effect, it is not economically desirable to use it excessively over the above range.

Such yellow rust removing agent of the present invention is very useful for sterilization and removal of microbial slime (yellow rust) generated in the water jet loom.
