Description

Antibacterial insect repellent processing method of textile woven, knitting

The present invention relates to the antimicrobial insect repellent processing of textile fabrics, knitted fabrics, and more particularly to a method of treating the release agent and the antimicrobial agent to a textile fabric or knitwear for clothing to provide a durable antibacterial insect repellent clothing.

It is medically proven that pests (ticks) that are invisible to the naked eye are inhabited by everyday wear, especially those that have been in direct contact with the human body for a long time (patient clothes, blankets, underwear, etc.). Although several methods of treating the release agent in the textile material have been proposed to improve the process, it has not been an effective and practical solution.

In addition, if clothing is worn for a long time, germs that cause odors in clothing or body are multiplied by sweat and excrement, which causes an unpleasant odor. This is also a situation where everyone must be satisfied with changing clothes frequently.

In order to solve these problems, the present inventors have sought a method of durable antibacterial and insect repellent treatment without impairing the function of the garment in the final product in the textile fabric and knitted fabric. The antibacterial and insect repellent treatment of textile fabrics and knitted fabrics is described in JP-A-62-299578, JP-A 4-308246, and JP-A 3-234877. By adopting a method of coating an insect repellent or antimicrobial-containing resin on a fabric, the final garment has a lot of problems in actual use due to its stiff texture or poor fit. There was a disadvantage that can not.

The present inventors have overcome these problems of the prior art and have succeeded in treating antimicrobial insect repellents in fabrics or knits while maintaining durability without coating.

It is an object of the present invention to provide an antimicrobial releasing garment having excellent and durable antibacterial insect repellent.

Another object of the present invention is to provide a durable antibacterial insect repellent processing on the fabric or knitted fabric without coating.

The antimicrobial insect repellent processing method of the textile fabric and knitted fabric according to the present invention is 1 to 10% by weight of the nonionic water-soluble insecticide of the aromatic compound, 1 to 7% by weight of the nonionic water-soluble antibacterial agent of the phenyl amide, nonionic dialkyl fatty acid salt A first step of uniformly mixing and stirring the resulting catalyst with water so as to be 0.01 to 1.0% by weight to prepare a padding liquid; A second step of padding the fiber woven / knitted product so as to have a pick-up rate of 60% by weight or more in the padding liquid according to a conventional continuous processing step; And a third step of drying the padded fabric for 1 to 10 minutes at 60 to 95 ° C. while passing through the dryer, and then curing at 120 to 180 ° C. for 1 to 8 minutes while passing through a general tenter.

The fiber knitted fabric may be a fiber of any material, such as cotton, T / C blend, wool, or synthetic fiber.

The present invention will be described in more detail below.

The insect repellent which can be used in this invention is a nonionic water-soluble compound as an aromatic compound, As an example of the said insect repellent currently commercialized, the Nissen series of Daiwa Chemical Co., Ltd., Japan is mentioned. Further, the antimicrobial agent is a phenyl amide-based nonionic water-soluble compound, and examples of the commercially available antimicrobial agent include Amolden series of Daiwa Chemical Co., Ltd., Japan.

As a catalyst to be employed in the present invention, a diene A from Japan Daiwa Chemical Co., Ltd. is effective as a nonionic dialkyl fatty acid salt.

The insect repellent, the antibacterial agent and the catalyst are uniformly mixed in the padding bath with water in an amount of 1 to 10% by weight, 1 to 7% by weight and 0.01 to 1.0% by weight, respectively. Resin and a softening agent can also be added to the said padding liquid as needed. When the amount of the insect repellent, antimicrobial agent and catalyst is excessive, the processing performance is not improved, may cause harm to the human body, and the processing effect is not sufficiently expressed at a low content outside the range.

As described above, the uniformly mixed padding liquid is padded with a pick-up rate of 60% by weight or more, which is the processing target fiber woven / knitted fabric, according to a conventional textile processing process. The padded fabric is dried for 1 to 10 minutes at 60 to 95 ° C. while passing through the following dryer, and then cured for 1 to 8 minutes at 120 to 180 ° C. while passing through a general tenter, etc. Fiber woven and knitted fabrics are obtained. The textile woven fabric, any material such as cotton, T / C blend, wool, synthetic fibers can be applied.

The ranges defined above are not absolute, but if the process proceeds outside the ranges, sufficient processing effects cannot be obtained.

Hereinafter, an embodiment of the present invention will be described.

EXAMPLE

Aromatic Compound Nonionic Water Soluble Insect Repellent [Annisen CBP (Annisen CBP), manufactured by Daiwa Chemical Co., Ltd.) 4% by weight, Phenyl Amide Nonionic Water Soluble Antibacterial Agent [Amolden MCM 400 (Amolden), manufactured by Nippon Daiwa Chemical Co., Ltd. MCM400)] 4% by weight and a nonionic dialkyl fatty acid catalyst (Amolden A (Amoden A) manufactured by Daiwa Chemical Co., Ltd.)] were uniformly mixed with water to make a padding liquid.

The padding liquid was padded with 80% by weight of the pick-up rate according to the conventional textile fabric processing, and then dried at 80 ° C. for 4 minutes while passing through a dryer, and finally at 150 ° C. while passing through a tenter. Curing was performed for 1 minute.

The antibacterial insect repellent knitted fabric thus completed was tested for antibacterial and release performance by the following method.

1. Insect repellent test

sample

Test Methods

A plastic share with a diameter of 4 cm and a height of 0.6 cm is placed on the adhesive sheet, and six identical sashes are placed so as to make contact with the central share around it.

About 3,000 tick badges were put in the center of Shaye in the middle of the tick, and six curry around the ticks were placed alternately with the treated and untreated samples cut to a diameter of 4 cm. release g. This is placed in a plastic container for food preservation of 27 × 13 × 9 cm for each adhesive sheet, put saturated saline solution to reach the lid, keep the humidity in the container at about 75%, put it in a constant temperature of 25 ℃ + 1 ℃ and recover the tick The evasion rate suitable for the following formula was calculated | required. However, the test was repeated three times in consideration of suitability.
