Description

Textile fabric with insect proof function and production method thereof

The present invention relates to a textile technique, and more particularly to a textile fabric having an insect control function and a method of producing the same. Background technique

Today's commonly used textiles, such as clothes, mosquito nets, and sheets, do not have the function of mosquito repellent, and people's daily activities are often seriously affected by mosquitoes. Since the mosquito net does not have the function of repelling mosquitoes, when sleeping at night, the mosquitoes will fly in and bite the human body, so that people cannot fall asleep; because the clothes do not have mosquito repellent function, the human body will be bitten by mosquitoes, which seriously affects people's work and life.

In addition, mosquitoes can spread diseases, and different types of mosquitoes can spread different diseases. Recently, epidemic diseases such as Japanese encephalitis (called "JE") and dengue fever have been prevalent in parts of China, and the main routes of transmission of these diseases are through mosquitoes. Mosquitoes are a kind of harmful insects that are very common in summer and autumn. The harm to the human body is that they will transmit pathogens to healthy people after they bite a diseased animal or human body.

Polyethylene (PE) is classified into high density polyethylene (HDPE) and low density polyethylene (LDPE). High-density polyethylene has good water washing performance, and the dry cleaning performance is slightly poor. It must be at a higher temperature and a higher pressure to obtain a better bonding effect. According to these characteristics, it is widely used as a male village. Shirt bonding village. Low-density polyethylene has poor water-washing and dry-cleaning resistance, but it can be bonded at a lower temperature and has a good bonding strength, so it is widely used for temporarily bonding village cloth.

Terylene is an important variety in synthetic fibers and is the trade name of polyester fiber in China. It is based on purified terephthalic acid (PTA) or methyl terephthalate. Ester (DMT) and ethylene glycol (EG) are fiber-forming polymers obtained by esterification or transesterification and polycondensation, polyethylene terephthalate (PET), spinning and Post-processed fibers.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a cross-sectional view showing a textile yarn containing an insecticide in the present invention. Preferred embodiment of the invention

The above described objects, features and advantages of the present invention will become more apparent from the aspects of the appended claims.

In the present invention, the textile fabric having the long-lasting insect repellent function is composed of PE containing insecticide. Yarn and polyester yarns are woven by a blending process, which is warp-knitted and blended; the insect-repellent function is achieved by adding pesticides to PE yarns or polyester yarns. The PE yarn contains 1% ~ 80% by weight of insecticide (mosquito repellent), and the insect repellent uses the insecticide recommended by the World Health Organization (World Health Organization), including: cypermethrin, Cyfluthrin, cypermethrin, deltamethrin, cypermethrin, cyhalothrin and chloroether ester. The pyrethroids selected for domestic mosquito repellents include: methrin, dextromethrin and methotrexate.

Adding pesticides to textile fabrics can be done in the following three ways:

(1) The insecticide is contained in the drug yarn, and the polyester yarn contains no drug;

(2) Insecticides are contained in pharmaceutical yarns and polyester yarns;

Mixing the drug yarn 11 into the PE yarn containing no drug to form a PE yarn containing the pesticide;

3. Blending PE yarn containing insecticide and polyester yarn 12 to produce a textile fabric with insect-proof function.

Method 2: The pesticide is contained in the PE yarn and the polyester yarn.

The production process is as follows:

1. Pour the PE yarn and polyester yarn into the insecticide for 1 ~ 2 hours, and the temperature is between 100 ~ 200 °C to produce the pharmaceutical yarn 1 1 .

Insecticides can be selected from: cypermethrin, cyfluthrin, cypermethrin, deltamethrin, etofenproxil, cyhalothrin, chloroether ester, methrin, dextromethrin, methamphate, etc. One or several combinations, the addition ratio is 1 ~ 30 g / kg.

Insecticides may also be selected from deltamethrin 1.8 g/kg or cypermethrin 5.5 g/kg.

2. Blend the pharmaceutical yarn 1 1 with the polyester yarn 12 without insecticide to produce a textile fabric with insect resistance.

Method 3: The insecticide is contained in the polyester yarn, and the PE yarn is free of medicine.

The production process is as follows:

1. Soak the polyester yarn into the insecticide for 1 ~ 2 hours, and the temperature is between 100 ~ 200 °C to produce the drug yarn.

2. Blend the drug yarn 11 with the PE yarn without insecticide to produce a textile fabric with insect-proof function. Method 4: The insecticide is attached to the textile fabric by spraying or coating the outer layer of the polyester yarn, the PE yarn or the textile fabric with the coating of the insecticidal preparation, or directly immersing the textile fabric in the insecticide preparation. For the selection of pesticides, refer to method three.

Textile fabric washable test:

1. Take samples of 25cm*25cm textile fabric materials for use;

2. According to the World Health Organization washing test standard, add 0.5L water and l g soap to the large beaker, keep the pH value at 10 ~ 1 1 , water temperature 30 °C, until the soap is completely dissolved;

3. Place a sample of 25cm*25cm textile fabric into a beaker containing the above detergent, place the beaker on a shaker, and wash the textile fabric sample at a speed of 155 times/min. lOmin; then, remove the sample. Washing twice in clean water, cleaning the textile fabric sample also washed on the shaker at a speed of 155 times / min l Omin;

4. After washing, dry at room temperature of 30 °C, and store in dark conditions until the next wash. Each wash takes 1-3 days.

The above process is repeated at least 20 times.

Anti-grave test:

The sensitive species raised in the laboratory are Aedes albopictus (female) 2 to 5 day old adults.
