This relates to processing methods. (Prior Art) As a durable antibacterial processing method for fibers, a method is known in which fibers are treated with orcasilicon quaternary ammonium salt. Orcasilicon quaternary ammonium salt is said to have durable antibacterial properties by reacting with the primary hydroxyl groups of cellulose. This durability won't last well into November. In addition, antibacterial activity has been observed in bacteria, but
It does not have enough resistance to fungi. Another method is to mix fine powder of an antibacterial agent with an adhesive resin and make it adhere to the fibers to provide durable antibacterial properties. However, in this method, the texture of the fibers changes due to the adhesive resin used, and the antibacterial performance is not sufficiently durable. The method of kneading an antibacterial agent into fibers is excellent in terms of durability of antibacterial performance, but has the drawback that it causes changes in the physical properties of the fibers. (Problems to be Solved by the Invention) The object of the present invention is to provide durable and excellent antibacterial properties to polyamide 1ζ fibers, polyolefin fibers, or acrylic fibers without changing their texture. to the fiber (=
It is to provide a way to give (Means for Solving the Problems) The present invention uses one type selected from polyamide fibers, polyolefin fibers, and acrylic f&fibers, and a particle size of 2 μm.
! Methyl-2-pendimitazole carbamide (hereinafter referred to as M
The fiber is brought into contact with a stable aqueous dispersion of BC) and/or tetrachloro-4-(methylsulfonyl)pyridine (hereinafter referred to as TCMP) and heated at 80°C to 150°C. The present invention relates to a durable antibacterial processing method. The present inventor has discovered that MBC and TCMP, which are substantially insoluble in water,
We have investigated various ways to permanently fix the particles on the fibers without damaging the texture of the fibers, and found that the particle size was 2 μm.
11 or less, preferably 1μII+ or less, and uniformly and stably dispersed in water, the fibers are brought into contact with a dispersion liquid and heated to produce a very high yield of MB.
The present invention was completed based on the discovery that durable fibers with antibacterial properties can be obtained by adsorbing fine particles of C and TCMP onto the surface of the fibers. Examples of methods for producing the stable aqueous dispersion of MBC1 or TCMP used in the present invention include the following method. In other words, MBC1 or TCMP active powder) 10-50
5 to 30 parts of nonionic surfactant, 1 to 10 parts of dispersant
parts, thickener 0-5 parts, wetting agent 0-15 parts, antifoaming agent 0-1
First, a preliminary dispersion is prepared by adding water or the like to 0 to 15 parts of the solvent to make a total of 100 parts, and stirring with a homomixer or the like. Next, the preliminary dispersion obtained in this way is milled into MBC, or T, C: MP, with a particle size of 2μ1 by a wet pulverizer or the like.
1. Thoroughly pulverize, preferably to a size of 1 μm or less, to obtain a stable aqueous dispersion. If the particle size is 2 parts or more,
The adsorption yield on the fibers is poor and the washing resistance is poor. Examples of the dispersant include naphthalene sulfonic acid formalin condensate, but other anionic surfactants can also be used. Various thickeners such as polyvinyl alcohol, CMC, and heteropolysaccharides are used as thickeners. The antibacterial processing method for fibers according to the present invention includes a padding method and a dipping method. The padding method is M'B C or TCMPo, 1-5
After immersion or coating in the aqueous dispersion according to the invention containing 0 g/L, it is pre-dried. Next, it is heated for a predetermined period of time. As the heating method, dry heating, steam heating, or heating using electromagnetic waves may be used. Processing temperature is 100-15
Heating with normal pressure or high pressure steam at 0°C gives the most favorable results. The heating time is usually 1 minute to 60 minutes. The dipping method is a method in which fibers are immersed in an aqueous dispersion containing 0.05 to 10.0% by weight of MBC or TCMP based on the weight of the fibers to be treated, and then heated for a predetermined period of time. The bath ratio (fiber weight/water) is usually 1:10 to 1:20, and the treatment temperature is 80 to 150°C, usually 80 to 120°C. Processing time is 10 to 90 minutes, but usually 30 to 90 minutes.
60 minutes is sufficient. Examples of polyamide fibers include aliphatic polyamides such as nylon 6, nylon 66, and nylon 610, as well as aromatic polyamides. Examples of polyolefin fibers include polypropylene fibers and polyethylene fibers. Acrylic fiber is a synthetic fiber containing acrylonitrile as a main component. The present invention will be specifically explained below with reference to Examples, but these are not intended to limit the present invention. (Example 1) 40 parts of MBC, 10 parts of polyoxyethylene nonylphenol ether, 5 parts of naphthalene sulfonic acid formalin condensate, 0.5 part of polyvinyl alcohol, and 44.5 parts of water were stirred in a homomixer to prepare a preliminary dispersion. Next, this pre-dispersion of MBC was pulverized for 2 hours using Dyno Mill (manufactured by WAB, Switzerland) to obtain a stable aqueous dispersion.The particle size of MBC in this dispersion was as follows: 2μ
Those with n1 or less accounted for 80 wt% or more. Each test cloth was immersed in the diluted MBC aqueous dispersion thus obtained and subjected to a heating treatment. The concentration of MBC in the treatment liquid is 1.
The concentration was adjusted to 0 wt%. Bath ratio (fiber weight/water)
The time was 1:15. The treatment temperature and time were 100° C. and 530 minutes. Washing conditions: Water temperature: 40°C ± 1.5°C, 1 detergent, and knee beads. Kao) was washed for 10 minutes at a concentration of 2 g/L, rinsed with running water for 5 minutes, dehydrated, and dried. The MBC adsorption amount of each treatment I was measured as follows. That is, each treated solution was dissolved in formic acid, each solution was diluted, and the wavelengths of 220 II II+ were measured using a spectrophotometer.
It was determined by measuring the absorbance. The results are shown in Table 1. (The unit is weight percent based on the fiber weight part) (Example 2) Using each treated fiber obtained in Example 1, JISZ2
A mold resistance test of the fibers was conducted based on 911. That is, the following culture media 15 to 201 were poured into a Petri dish with a diameter of 9C1i and solidified, and each fiber test piece 501 was placed on top of this.
Place the cut pieces on a 50-sized plate, and spray 11 drops of each of the following mixed spore suspensions of the three mold strains (0,005% dioctyl sodium sulfosuccinate aqueous solution) on the surface with a sprayer, and heat at 28°C ± Cultured at 2°C. After two weeks, the growth status of the mold was observed.

5 parts were stirred with a homomixer to prepare a preliminary dispersion. Next, this preliminary dispersion of TCMP was wet-pulverized for 2 hours using a Dyno Mill to obtain a stable aqueous dispersion. In this dispersion, 80 wt% or more of TCMP particles having a particle size of 2 μIII or less accounted for 80 wt% or more. Using the stable aqueous dispersion of TCMP thus prepared, nylon fibers, polypropylene fibers, and acrylic fibers were treated in the same manner as in Example 1 to obtain fibers with antibacterial properties. The antibacterial fibers obtained above were subjected to the same mold resistance test as in Example 2. The results are shown in Table 3. It is clear that each of the fibers listed in Table 4 has wash-resistant antibacterial properties. [Comparative Example 1] A slurry consisting of 40 parts of MBC, 10 parts of polyoxyethylene nonylphenol ether, 5 parts of naphthalene sulfonic acid formalin condensate, 0.5 part of polyvinyl alcohol, and 44.5 parts of water was ground in a ball mill for 1 hour. The mixture was treated to form an aqueous dispersion. The particle size of MBC in this dispersion was mostly greater than 5 μn1. Using the MBC dispersion thus obtained, each fiber was treated in the same manner as in Example 1. Next, a mold resistance test similar to that in Example 1 was conducted using the treated fibers. The results are shown in Table 4. It is clear that the fibers treated with the dispersion do not provide wash-resistant antimicrobial performance.
