Description

Mosquito bite prevention fabric and manufacturing method

The present invention relates to a fabric for preventing mosquito bites and a method of manufacturing the same, and more particularly, to a fabric and a method for manufacturing the mosquito do not penetrate while giving a light and cool touch without sweating the body.

Mosquito is the scientific name of the Culicidae , an insect of the fly family Mosquito, about 3,500 species live in the world, and 56 species in 9 genera are known to live in Korea, and it has a life cycle of eggs, larvae, pupa and adults. It is a metamorphosis insect.

 Female mosquitoes mate only once in their lifetime, after which they avoid male mosquitoes, and require a lot of nutrients (animal proteins) to lay eggs. These nutrients are taken from the blood of animals. It is a harmful insect that can transmit not only stress, but also fatal diseases to humans.

According to scholars, the mosquito's saliva consists of six, two saw blade needles to cut obstacles, two drills to penetrate the skin, and when the mosquito saliva reaches the blood vessels, There is one needle that secretes a substance called hirudin, and one blood vessel for sucking blood by inserting a stem, and its overall diameter is 0.000743 mm in average and 0.243 mm in length. Mosquitoes have a structure that can easily penetrate thick fabrics, such as jeans, as well as work clothes and military uniforms, if there is a gap to catch the saliva.

 Infectious diseases caused by mosquitoes include malaria, Japanese encephalitis, epithelial disease (denomyosis), and dengue fever. Malaria and Japanese encephalitis are dangerous diseases with a 5-30% mortality rate in Korea, and the number of infected people continues to increase every year. In addition, encephalitis virus is a fatal disease for children under 15 years of age. Diseases such as epithelial disease and dengue fever are also transmitted from mosquitoes. Especially dengue fever is reported to have a 10-50% mortality rate. .

 In all countries suffering from diseases caused by mosquitoes as described above, a lot of research has been conducted to combat mosquitoes without mosquito bites, but there are no products that have yet been completely mosquitoed or mosquito bites.

 In order to combat mosquitoes as described above, there is a method of combating mosquitoes by spraying aerosols or releasing a mosquito (a mosquito fragrance).

 However, the US Centers for Disease Control reports that spraying aerosols causes shortness of breath, headaches, and dizziness in humans due to harmful ingredients such as amiprotrin, permrine, and phthaldrin in aerosols. The harmful ingredient of malachite, green fragrance, contains formaldehyde, which can cause respiratory diseases such as asthma, vomiting, and diarrhea. There are ways to spread smoke by burning wormwood, spreading cinnamon scent or spreading it on the body, but this works temporarily, but after a certain period of time, mosquitoes fly again. .

 Also, in order to avoid mosquito bites, people live with insect screens or mosquito nets, but people cannot always stay inside the nets or mosquito nets, so they are forced to stay mosquitoes. No help was given to fishermen, anglers, livestock care workers, and many at night.

 Therefore, in order to avoid mosquito bites during night activities as described above, in the Korean Utility Model Registration No. 20-0167680, in forming a top with a cap and a bottom fastening with velcro fasteners, the top and bottom are doubled. It consists of inner and outer ledges, and the inner ledge is composed of ledges with relatively large holes, and the outer ledges are composed of ventilated ledges with perforated holes that mosquitoes can't penetrate. Insect penetration prevention clothing described by installing this excellent rubber spring is described.

 However, the insect penetration prevention clothes described above are composed of two layers of internal and external nets, and it is extremely difficult to install a rubber spring having excellent elasticity at appropriate intervals between the internal and external nets. Even if the mosquito can not penetrate through the clothes to suck the blood is difficult to prevent mosquito bites.

 In addition, the Republic of Korea Patent Publication No. 10-0828077 in the mesh-shaped insect repellent fabric, the mutual length is different on the surface of the fabric, one end of the rounded first protrusion and the second protrusion formed mutually alternate To provide a fabric structure for insect repellent, the first projection and the second projection has been described a technique of forming a length of at least 0.35mm or more from the surface of the fabric.

 The reason why the length of the protrusion is at least 0.35 mm from the fabric surface is that the mouth of the mosquito snout on the fabric surface does not touch the human skin because the average length of the mouth of the mosquito is 0.24 mm.

 However, the above-mentioned insect repellent fabric is to maintain the shape by applying heat through a forming plate formed with a protrusion having a different length after weaving a mesh-type fabric having a breathable, but if you make a insect repellent clothing with such fabric If the elbow or the body's bends and the sitting part are in contact with the skin as the insects are elongated, the mosquito bites may cause problems.In addition, after weaving the fabric, post-processing is required, which increases the cost of the fabric. There is a problem that can be caused.

 In addition, mosquito-repelling clothing may be used to coat the fabric fabric with a mosquito-like fragrance, but if the perfume loses its function due to washing or friction, the mosquito is believed Bite occurs.

 On the other hand, the present invention is filed by the applicant of the present application No. 10-2009-0039322 (2009. 05. 06. Application; the name of the invention: fabrics and garments for preventing mosquito bites and manufacturing method thereof) and No. 10-2009-98303 ( 2009. 10. 15. Application, the title of the invention: to prevent the mosquito bites fabrics and garments) and the manufacturing method).

 Applicants of the above applicants can prevent mosquito bites, but the touch is too rough, so it is not suitable for use for general clothes other than mosquito bite prevention purposes, and the surface of the fabric of the folded portion is expanded when bending In order to prevent the occurrence of a problem that the fabric is punctured by a needle that acts as a saw blade needle and a drill for cutting the obstacles of the mosquitoes to open the gap to the present invention to reach the present invention.

 The present invention is to solve the conventional problems as described above, an object of the present invention is to provide a fabric that does not take sweat on the body, while giving a light and cool touch, mosquitoes do not penetrate.

 In addition, the present invention has a second object to promote the health of those who are active at night in the summer by providing a mosquito bite prevention fabric and a manufacturing method thereof having a moisture absorption quick-drying, far infrared rays and anions, and antibacterial action. .

In addition, another object of the present invention is to provide a fabric tailored to the taste of the consumer by preventing the mosquito bite fabric is not only plain weave but also twill weave.

 In order to achieve the above object, it has been found that mosquitoes do not get stuck in the fabric due to the interaction between tough and hard yarns, dense and seamless fabric density, and smooth fabric surface.

 Among them, the key factor is the dense and seamless fabric density.

 The present inventors pay attention to the above fact, the fabric of the invention is fineness of 70 ~ 150D / 24 ~ 72F, using a multi-filament polyester stitching yarn without twist as a warp yarn warp density 100 ~ 210 bone / inch, weft density Weaving is done at a density of 70 to 120 bones / inch.

 In the above, when the fineness of the polyester yarn is less than 70 denier, the hygroscopicity is lowered when weaving densely and the fabric sag occurs, and the feeling of freshness is lost in the summer, and when the density exceeds 150 denier, the fabric is soft. There is a problem that the stiffness and wear is bad, and the fabric is excessively thick, resulting in heavy clothing.

 In addition, polyester stitching yarns contain 1 to 5% by weight of silver, copper or bioceramic to prevent polyester from generating static electricity, as well as dissipate far infrared rays and anions from the fabric and perform antibacterial activity. Can help to promote

 When the metal powder is less than 1% by weight, the antistatic effect is lowered. When the metal powder is more than 5% by weight, there is a problem of increasing the unit price while decreasing the strength of the yarn.

 The use of stitching yarns that do not twist multifilament yarns on polyester yarns increases the volume of the thread by the thin filament yarns that are entangled together like cotton, increasing tightness between the yarns and the yarns, resulting in tight and almost no crevices. Mosquitoes can not penetrate the fabric.

 In addition, the capillary phenomenon of the fine space formed between the yarn and the yarn absorbs sweat well and discharges out to exert moisture absorption quick drying gives a soft and refreshing wearing feeling.

 In addition, in the present invention, if the inclination density of the fabric is less than 100 bones / inch, and the weft density is less than 70 bones / inch, not only the voids of the fabric are increased but also the phenomenon of sagging and the mosquito stings may be easily penetrated by making clothes. There is a problem, it is difficult to weave when the warp density exceeds 210 bones / inch and the weft density is 120 bones / inch, and a problem occurs that the moisture absorption quick-drying is reduced even after weaving.

It is common sense to increase the weaving density when the fineness of the yarn to be used is thin, and to decrease the weaving density when the fineness is thick.

 In addition, the present invention is a method for weaving the fabric described above

  First preparing a multi-filament polyester stitching yarn with fineness of 70 ~ 150D / 24 ~ 72F;

 Weaving preparation step of passing through the prepared polyester stitching yarn to a density of inclined density 100 ~ 210 bone / inch; And

 Weaving prepared weaving is characterized in that it consists of a step of weaving into a plain or twill weave by supplying the weft so that the density of the weft density 70 ~ 120 bones / inch.

 In the above, the polyester stitching yarn to powder 1, 5% by weight of silver, copper or bioceramic to prevent the static electricity generated by the polyester spinning, as well as by emitting far infrared rays and anions in the fabric and antibacterial It can promote the health of the users, and when the metal powder is less than 1% by weight, the antistatic effect and antimicrobial effect is lowered, and when the weight exceeds 5% by weight, the problem of raising the unit price while lowering the strength of the yarn.

 In addition, in the present invention, if the inclined density of the fabric is less than 100 bones / inch, the weft density is less than 70 bones / inch, the breathability is good and weaving is convenient, but the stitching yarn is loosened and the gap is increased in the fabric, so that the mosquito bites the bite If the warp density exceeds 210 bones / inch and the weft density exceeds 120 bones / inch, it may cause difficulty in diameter preparation in warp preparation, consume excessive energy when weaving, and cause fear of trimming due to friction. It is difficult to weave the back, and even after weaving, there is a problem that the moisture absorption quick-drying is lowered. In general, when the number of times is three times, the density is high, and when the number is the number of times, the weave is low density.

In addition, the polyester yarn is a circular cross-section filament yarn, but the cross section of the filament

If you use the type or ☆ type sectional section yarn, the fabric will be rough and it is good to use for the summer season.Because a lot of small voids are formed in the fabric, the air permeability is good and you can get the advantage and functionality to get a cool feeling in the summer. Can be.

 In addition, the fabric in the above can be plain weave, but not only good weaving of twill weave, but also increase the density of the fabric can prevent the penetration of mosquitoes, 1/2 to 1/3 or 2/2 to 2/3 It is recommended that weaving with 3 to 5 twill weaves. In the case of multi-form harness twill exceeding this, frictional fastness is lowered and the fabric is easily worn or mosquitoes may be bitten by warp or weft jungle. This can cause problems, and weaving into basic twill is better than changing twill.

On the other hand, when spraying or coating the fragrance that emits the smell of mosquitoes that are already known to the mosquito bite prevention fabric of the present invention, because the mosquitoes do not approach temporarily, you can not hear the sound of mosquitoes to obtain a psychologically stable effect. Mosquito bites do not improve.

 According to the present invention provides a fabric that does not penetrate the mouth of the mosquitoes while good moisture absorption and quick drying, and can be used in the long term as long as the clothing is broken and there is no puncture when the clothing is manufactured by using the fabric, and always maintains comfort It is effective in promoting human health by preventing mosquito-borne diseases because people who do night activities in summer do not bite mosquitoes.

 In addition, since the mosquito bite prevention fabric of the present invention does not need to use other varieties, spray mosquitoes or mosquito scent, there is an effect that the mosquitoes simply do not have to prepare a separate preparation.

In addition, the present invention can easily inhale and discharge the sweat emanating from the human body during the hot summer season, always maintains comfort, reducing the generation of static electricity when using a metal-containing yarn containing bioceramic, far infrared rays and negative ions It produces an antibacterial effect and has an excellent effect on health promotion.

The fabric of the present invention as described above has a fineness of 70 ~ 150D / 24 ~ 72F, using a twisted polyester stitching yarn as the weft yarn, the warp density of 100 ~ 210 bone / inch, weft density of 70 ~ 120 bone / inch By weaving at a density, the kneading filaments may be weaving using a weaving yarn using filaments containing 1 to 5% by weight of silver, copper or bioceramic powder.

 In addition, the present invention is a method for weaving the above-described fabric,

 First preparing 70-150D / 24-72F and twistless polyester stitching yarn;

 Weaving preparation step of passing through the prepared polyester stitching yarn to a density of inclined density 100 ~ 210 bone / inch; And

 Weaving prepared weaving is characterized in that it consists of a step of weaving into a plain or twill weave by supplying the weft so that the density of the weft density 70 ~ 120 bones / inch.

The binder filaments are mixed with silver, copper or bioceramic fine powder when the polyester is spun to maintain the efficacy for a long time, and it is preferable to use the content of 1 to 5% by weight based on the polyester.

That is, the characteristics of the present invention as described above is to supply a good moisture-absorbent quick-drying fabric while preventing the mosquitoes penetrate, and how appropriately select and arrange the fineness and fabric density suitable for the purpose, mosquito Since it is used during the hot summer season, it is important to have good hygroscopic quick drying and prevention of static electricity and good antibacterial properties.

 Hereinafter, the present invention will be described in detail with reference to Examples, but the present invention is not limited to the Examples, and various modifications may be made within the scope of the present invention.

      In addition, although the present invention has been described as using a twist-free polyester stitching yarn, it will be appreciated that nylon, vinylon or rayon fibers may be used for the purpose of the present invention.

 <Example 1>

 Weaving 100% polyester stitching yarn without kink is 75D / 36F for warp, weft 100D / 24F, weaving density of 190 bones / inch and weft density of 90 bones / inch. The garment was manufactured using the fabric obtained by weaving with twill.

 <Example 2>

 Using non-twisted polyester fiber containing 3% by weight of bio-ceramic, the fineness is 75D / 36F and the weft yarn is 120D / 72F, except that the warp density is 190 bones / inch and weft density 85 bones / inch. Clothing was prepared in the same manner as in Example 1.

 <Example 3>

 A twist-free polyester stitching yarn containing 3% by weight of silver powder is used.The fineness is 75D / 36F for warp yarns and 120D / 72F for warp yarns.The warp density is 190 bones / inch and the weft density is 80 bones / inch. / 3 A garment was made using the fabric obtained by weaving with 5 sheets of twill.

 <Example 4>

 A garment was manufactured in the same manner as in Example 3, except that 2% by weight of the copper powder was contained.

     Example 5

     A garment was manufactured in the same manner as in Example 2, except that the fabric was plain weave.

The clothing obtained in Examples 1 to 5 was found that all of the mosquitoes can not penetrate the experimental results.

 In particular, it exhibited comfort by absorbing and discharging the sweat of the human body well at high temperature and high humidity, and in the case of twill weave, a softer touch was felt, but in the case of the plain weave of Example 5, the touch was slightly rough.

 In addition, in Examples 2 to 5, there was no static electricity even in friction, and it was found that even more comfortable due to the emission of far-infrared rays and negative ions, no bacteria were generated even when left in high humidity.

Since the mosquito bite prevention fabric of the present invention can not be a blood-sucking mosquito, if the clothing made of such a fabric is widely spread will solve the unwanted pain from the mosquitoes, will be able to enjoy a more comfortable life.

 According to the fabric of the present invention, by adding a metal powder or a bio-ceramic powder that emits far-infrared rays that can block ultraviolet rays and emit anion to activate metabolism, the function of health promoting clothing can be pursued by adding to the polyester filament spinning solution. Naturally, you can add natural fragrances, such as herbs or lavender, that are mosquito-repelling to polyester filaments.

 On the other hand, in the case of the garment using the fabric obtained in the above Examples 1 to 5 it was found that even after 10 washes mosquito bites did not reduce the prevention effect.

 In addition, the fabric of the present invention after spraying the lavender scent of mosquitoes dislike mosquitoes bar, mosquito bite is not only prevented before washing as well as the sound of the mosquitoes after washing once, but mosquito bite is prevented, but the mosquito sound is lavender Natural flavors such as lavender and herb flavors were ineffective after washing as they did not differ from those without.
