Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for treating polyester fiber products with anti-bacterial properties, and more particularly to a method of completely immobilizing sterilizing Mll within the polyester fiber structure to impart anti-bacterial properties to the fibers.

Socks, underwear, sports clothing, and clothing cost 1 gi of user's skin.
The secretions, juices, peelings of the skin, etc. form a layer, and these become a good medium for bacteria to propagate. In some cases, it can also be the cause of infections such as skin diseases. In addition, when mattresses, rugs, curtains, wall fabrics, etc. are used for judicial officials or for wet ash cultivation, mold and mildew develop, resulting in a decline in quality due to fiber force ratio contamination.

Attempts have been made to sterilize textile products in order to protect them from debris and damage, keep them hygienic, and maintain good quality, and several methods have been developed so far. Heaven b- is C. The most common method is to immerse or spray the product in a disinfectant, but as a method to further strengthen the adhesion of the disinfectant, for example, by dipping the product with a disinfectant, A method in which a part is bonded to a part of the fiber molecule via an organosilicon compound, or a method in which a bactericidal compound such as an organochlorine compound is adhered to the fiber surface using a synthetic resin with good spreadability and is fixed. A method is known in which an organometallic compound is bonded to the composition of a 1-i' fiber material to impart antibacterial properties.

However, the fibers used for these purposes are exclusively cotton wool, @, acetate, acrylic yarn, polyamide yarn,
These include vinyl chloride yarn, polycretan yarn, etc.

In principle, these fibers have functional groups in their constituent molecules that have the ability to chemically or physically bond with molecules of a third substance, or they have been modified to have all such functional groups. The physical properties of certain Fi fibers have excellent compatibility with synthetic resin adhesives.

In addition, cationic activator-based bactericides are generally used because of their R compatibility with fibers, but they have problems with durability and are said to have the drawback of attracting dirt and conspicuous staining. There is 1.

However, 71 knee IJ ester fibers have reactive side chains 1
It has no functional groups, and has poor affinity with adhesives, so it is not possible to fix the plate in combination with adhesives, and the processing conditions of the fiber finishing process may be affected by IH, which may damage the original texture of the fibers. figure,
In addition, the present inventor has developed a method for imparting good abrasion resistance to polyester fiber products! ! ! After much consideration, we decided to immobilize the incubator by immersing it in the gaps between the aggregates of the polyester-C fibers, which have excellent washability and long-lasting properties. We have achieved the antibacterial processing method of the present invention that maintains the bactericidal effect for a period of time.

That is, the gist of the present invention is to bring a polyester fiber product into contact with an aqueous solution containing gold as a lethal agent//θ~=300
The present invention relates to a method for processing polyester fiber products to prevent corrosion during heating.

In detail, the present invention is applicable to all polyester fiber products such as raw cotton, yarn, string, woven and knitted fabrics, and other processed products.

The disinfectants used in the method of the present invention include those with strong hydrophilicity, those with coloring properties, those with laughing gas or strong irritation, and
Most of the t2 can be used, except for those with strong sex, those that change in quality when exposed to sun irradiation, and those with strong 4 sex, but 0 has poor dyeing, promotes discoloration, % toshin leaching, and transfer. Examples of preferred bactericidal 1L compounds that do not cause deterioration of fJX glaze products due to staining, yellowing, off-odor, etc. include 3-methyl-guisonorobylphenol (3M&P), thymol, p-talolol m-cresol, p- -oxybenzoate alkyl ester (alkyl is methyl, ethyl, n- and 180-talovir, n- and 8θC- or tθr-butyl, pentyl, etc.) p-chloro-m-xylenol (POMX),

Oxyquinoline button 1 includes cabbane, difortan, etc., and 2 or more apples may be mixed in. The aqueous quinolinium containing oxyquinoline used in the method of the present invention contains bactericidal compounds, solvents, and surface-activating adjuvants. , water and, if appropriate, an emulsion stabilizer, etc., are mixed to form a homogeneous liquid solution.

It is further diluted with water. In addition, for bactericidal compounds with low solubility and no suitable solvent, a separating agent (naphthalene sulfonic acid formalin condensate, etc.) and water are added to form a slurry, and the mixture is sufficiently atomized using a ball mill, homomixer, colloid mill, etc. It is prepared by drying the flowable agent or drying the flowable agent to form a powder, and diluting this flowable agent or powder with water.

Since disinfectant ingredients, flowable agents, and powders are used after being further diluted with water, it is convenient to prepare them at once as much as possible.
Due to formulation difficulties, the concentration of the bactericidal compound may be 0% or θ~
(Amount of M) is produced.

The fiber processing method according to the present invention can be broadly divided into a pressure method and an ordinary pressure method. The pressurization method involves sterilizing in a tightly sealed container.

~30), treatment temperature/lθ ~/60° C., treatment time 90 minutes to 9 hours.

The normal pressure method is a method in which a solution containing a bactericide is applied to the textile product to be treated by dipping or bending the face, and after reaching a predetermined adhesion rate, it is heated for a predetermined period of time to allow penetration and fixation. In this case, the concentration of the bactericidal compound in the aqueous liquid containing the bactericidal blast 1 is θ, θ! ~! θ． OJ//

Processing is carried out under conditions selected from ~30°0 and a treatment time of 5 minutes to 70 seconds. In addition, since illegal treatment is performed at normal pressure and high temperature, it is necessary to select a bactericidal compound that has a low vapor pressure at the treatment temperature.

In either method, the bactericidal compound is applied to the M amount of the fibers at a rate of θ depending on the pathogenic efficacy of the bactericide. It is necessary that a predetermined amount or more within the range of 0θl-2.0% is incorporated into the fiber, and the effectiveness rate (the bactericidal compound in the aqueous liquid containing the bactericide) depends on the treatment method and the sterilization ratio used. (Ratio of incorporation into fibers) 1-The most effective disinfectant is determined by experimental confirmation.

In the method of the present invention, an appropriate bactericidal compound is stably immobilized by infiltrating the interstices of the aggregates of assembled polymers of polyester camphor fibers, and the efficacy is maintained stably for a long period of time and has excellent cleaning properties. shows. Polyester fiber products treated by the method of the present invention do not exhibit deterioration in air flow, water repellency, dust adsorption properties, or other properties that impair the customization of polyester fibers. Furthermore, since the adsorbed sterilizing active ingredient is released very gradually, the amount of sterilizing ingredient that comes into contact with the user of the textile product is suppressed to an extremely small amount, resulting in high safety.

In addition, in the manufacturing process of polyester fiber products, there is usually an operation in which the mulberry color is processed under such conditions during the finishing process, so the 5-strand method can be inserted into the process as appropriate. For example, if the method of the present invention is used in combination with the dyeing process, the objectives can be achieved at the same time, which is extremely simple and economical.

Next, the present invention will be specifically explained using examples, but the present invention is not limited to the following examples as long as it does not exceed the gist thereof. In addition, in the examples, the term "related" refers to protection unless it is particularly intended to prevent injury.
