JP2001131865A - Antifungal and antibacterial treatment of fiber with red wine stum - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a production process for antifungal fiber products that have excellent fungistatic action by utilizing red wine stum. SOLUTION: In this invention, fiber products made of cotton, hemp, silk, and the like, are pretreated with a pretreatment solution including a cationizing agent. The cationized fibers are brought into contact with a solution including polyphenols in the red wine stum to effect their reaction. Then, the stum-treated fiber product is treated with a mordant solution including a mordant to effect the fixing reaction.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an excellent plant antibacterial process characterized by containing an extract of red wine grape liquor having high antibacterial properties as an active ingredient.

[0002]

2. Description of the Related Art As a conventional antibacterial processing agent, organic (36)
Group) and inorganic type (group 1), and about 110 or more antibacterial agents are used as a whole. Each has its pros and cons, and some of them have skin irritation, high environmental load, and ecosystem abnormalities. Excessive antibacterial processing is abolished by the structure of the dye molecule, and selective sterilization (discriminating the type of microorganism and sterilizing only the harmful microorganisms of interest) is possible. Development is desired.

[0003]

In the present invention, in view of such circumstances, as a result of intensive studies, the polyphenols contained in red wine grape liquor have a stable and high antibacterial property,
It is an object of the present invention to provide a method for improving the adverse effect on human skin by a conventional chemical antibacterial agent, and contributing to the improvement of the negative effect on the ecosystem due to the disposal of the chemical antibacterial agent on the global environment.

[0004]

The process for producing an antibacterial and fibrous product having a bacteriostatic and bacteriostatic action using a red wine grape juice extract solution according to the present invention comprises contacting the textile with a pretreatment liquid containing a cationizing agent. After the cationization treatment, the solution is brought into contact with a solution containing the polyphenol extract contained in the red wine grape liquor to cause a reaction, and then is brought into contact with a mordant containing a mordant.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The red wine grape juice used in the present invention is obtained by extracting from a part of a grape fruit or a seed plant.

[0006] The red wine grape liquor used in the present invention is the European grape Vitis vinifera L. And American grape Vitis Labrusca L.
And Manshuyama Grape Vitis amuren
sisRuppr. Red wine grape varieties made of varieties and mixed varieties. A liquid product of this plant is commercially available.

[0007] The fiber product is cationized by contact with a pretreatment liquid containing a cationizing agent, and then reacted with a solution containing a red wine grape extract, followed by contact with a mordant liquid containing a mordant. And light fastness is improved.

The fiber material used in the method of the present invention is preferably a natural fiber such as cotton, hemp, silk and wool. The shape of the fiber may be any of yarn, woven fabric, knitted fabric and non-woven fabric.

In the present invention, the fibers are subjected to desizing, scouring, bleaching and the like, if necessary, and then contacted with a pretreatment liquid containing a cationizing agent for cationization treatment. Various commercially available cationizing agents can be used.

The bath ratio during the cationization treatment is often about 20 to 100 times the weight of the fiber product, the bath temperature is about 60 ° C. to 90 ° C., and the treatment time is about 30 to 90 minutes. The cationizing agent concentration is set appropriately.

The bath ratio during the reaction treatment with the solution containing the red wine grape extract is from 20 to 100 based on the weight of the textile.
The bath temperature is about 60-90 ° C, and the processing time is about 30-90.
It is often the minute, but is not necessarily limited to this range. The concentration of the solution containing the red wine grape extract can be selected from a wide range depending on the purpose of the antimicrobial product.

[0012] After the reaction treatment, a contact reaction is carried out with a mordant containing a mordant, and this step is an optional step, provided in terms of the fixation of the polyphenol contained in the red wine grape extract solution to the fiber and the color fastness. Is more preferred.

As the mordant, besides aluminum acetate, aluminum sulfate, aluminum chloride and alum, iron mordant (iron acetate, ferrous sulfate, iron nitrate), copper mordant (copper salt) and the like can also be used. .

The bath ratio at the time of mordant is 1 to the weight of the fiber product.
The bath temperature is usually about 0 to 100 times, the bath temperature is from normal temperature to boiling temperature, and the treatment time is about 10 minutes to 1 hour, but is not necessarily limited to this range.

After completion of the antibacterial processing step of the fiber with the red wine grape extract solution, post-treatments such as soaping and washing with water are carried out as appropriate, and then dried with sunlight or hot air.
