An umbrella is a tool for shading or sheltering from rain and snow. Generally made of oil paper, oil cloth or plastic cloth. Umbrella in English comes from Latin Umbra, which means shade and shadow. Umbrellas are usually made of malleable cloth, as well as other materials that can be used as skeletons and wound metal wires. When in use, lift it by hand. Although the umbrella was originally invented to keep out the sun, now it is most often used as a tool to keep out the rain in rainy days. Other functions of umbrellas include being used as decorations, crutches and even weapons. Hong Kong's time-honored Liang Suji umbrella is one of the umbrellas that can be used as weapons.
There are mainly three kinds of fabrics for umbrellas, and the cost from low to high is: polyester, PG cloth, nylon and transparent plastic.
Umbrella tapestry
The characteristics of polyester cloth are: bright colors, obvious creases after the umbrella surface is rubbed on the hand, and it is not easy to recover. There will be resistance when the cloth is rubbed, and there will be a rustle when it is rubbed. Coating a layer of silver glue on polyester is what we usually call a silver glue umbrella. Silver tape has a good anti-ultraviolet function, but after a long time of use, silver glue is easy to separate from the fold. Coating a layer of silver powder on polyester is what we usually call an umbrella with pearlescent cloth. Pearlescent fabrics are very popular with ladies because of their bright colors, but the effect of preventing ultraviolet rays from the sun is not ideal.
Umbrella PG cloth
PG cloth is also called bump cloth, and high-density bump cloth is a new kind of cloth. PG has the following characteristics: the color is dull and dark. The cloth feels like cotton cloth and has good light resistance. PG cloth is more expensive, but it has ideal anti-ultraviolet function, stable quality and grade color. This is a good umbrella cloth. Generally, PG cloth is only used for high-grade umbrellas.
Umbrella nylon
Nylon cloth is also an advanced variety of umbrella cloth. This poncho is brightly colored and feels like silk to the hand. When rubbing back and forth by hand, the resistance is very small. However, this kind of cloth has a weakness, which is greatly influenced by air humidity, and the umbrella cloth shrinks seriously, sometimes even affecting the normal opening and closing of the umbrella cover. Therefore, there are not many umbrella fabrics in common use.
Umbrella transparent plastic
Transparent umbrellas that have become popular in recent years are made of POE or PVC plastics, some of which have various patterns and colors.
Umbrella-shaped vinyl base fabric
Compared with other umbrella fabrics, vinyl base fabric has the following advantages: 1. It is not easy to age, and the long-term use of silver layer material is easy to cause the coating to age and fall off; 2. Cooling: the sunshade made of vinyl fabric can effectively cool down by 3-5℃ in the sun; 3. Super UV protection. Due to the different vinyl technology or fabric quality, the real anti-ultraviolet performance of sunshade on the market is also different. A more convenient test method is to use the flash on the mobile phone and use the shade cloth to cling to the flash in the dark to see if there is light leakage.
oilpaper umbrella
Oil-paper umbrella originated from
oilpaper umbrella
A paper umbrella made in China has also spread to Japan, Korea, Vietnam, Thailand, Laos and other parts of Asia, and oil-paper umbrellas with local characteristics have also been developed in various places. As some Hakkas moved to Taiwan Province Province to settle down, China oil-paper umbrella also developed in Taiwan Province Province. Oil-paper umbrella is not only a daily necessities for sun protection and rain protection, but also an indispensable item in wedding etiquette. In traditional Chinese weddings, when the bride gets off the sedan chair, she will cover her with a red oil-paper umbrella to ward off evil spirits. In traditional Japanese weddings, the bride is also covered with a red oiled paper umbrella. Old people prefer purple umbrellas symbolizing longevity, and white umbrellas are used at funerals. Traditional Japanese dances will also use oil-paper umbrellas as props, and tea ceremony performances will use "fan umbrellas".
In the early Hakka villages, due to the homophonic sound of "paper" and "son", when a Hakka woman gets married, she usually takes two paper umbrellas as a dowry, one of which stands for "early birth of your son", and the word "umbrella" has four characters, which also symbolizes many children and grandchildren, and the umbrella surface of the paper umbrella forms a circle, "oil" and "you" male/kloc-
In religious celebrations, you can often see an oil-paper umbrella propped on a sedan chair as a shelter from the wind and rain, which means perfection and serves as a symbol of people's shelter from rain, sun and evil spirits.
At present, umbrellas used in daily life are mostly foreign umbrellas, and oil-paper umbrellas are mostly sold to tourists as works of art and souvenirs.
Umbrella transparent umbrella
Transparent umbrella is a fashionable and personalized umbrella that women like. Suitable for rainy days with poor visibility, and the line of sight of transparent umbrella cloth is brighter. There are many colors of transparent umbrellas, such as solid color, colorless, transparent, and other colors. Some transparent umbrellas are printed with fashionable patterns to increase fashion and interest, and the styles are straight and folded. The umbrella cover of this kind of umbrella is mostly thin plastic, which is easy to be damaged and cheap. Most people who use transparent umbrellas are women.

Umbrella sun umbrella
Sun umbrella is a kind of umbrella mainly used to prevent direct sunlight.
Choosing an anti-ultraviolet umbrella mainly depends on the fabric of the umbrella. The research shows that the thick canopy fabric has better ultraviolet resistance than the thin canopy fabric. Generally speaking, cotton, silk, nylon, viscose and other fabrics have poor anti-ultraviolet effect, while polyester has better effect. Some consumers think that the thicker the umbrella cover, the better the anti-ultraviolet performance, but it is not. For example, the Paradise Umbrella series has developed a very thin but very tight fabric, and its protective performance far exceeds that of ordinary fabrics; In addition, the darker the color, the better, with satin fabric as the best, followed by twill and plain weave.
parasol
Experts also remind consumers to recognize the anti-ultraviolet performance label. Domestic and foreign standards generally use UPF value, that is, the value of ultraviolet protection coefficient, to evaluate the ultraviolet protection performance of textiles. UPF value is the ratio of the average amount of ultraviolet radiation to unprotected skin. The higher the UPF value, the better the ultraviolet resistance. The forthcoming national standard stipulates that only when UPF>；; 30, and the transmittance of UVA is less than 5%, which can be called anti-ultraviolet products, and the protection level is UPF 30+; When UPF>；; 50, indicating that the product has excellent ultraviolet protection performance, and the protection level is UPF50+.
In the market of sunscreen products this summer, anti-ultraviolet umbrellas are favored. When consumers choose an ultraviolet-proof sun umbrella, they should master its characteristics in order to choose a good umbrella with satisfactory appearance and quality.
Children's umbrella
Children's umbrellas are specially designed and produced by umbrella manufacturers for children.
Children's umbrellas are divided into three categories:
Children's Umbrella: This kind of umbrella is suitable for children aged 6 to 9. Generally, the umbrella cover is larger, slightly smaller than that of adults and lighter. The umbrella handle and umbrella body are specially designed;
Second, children's umbrella: this umbrella is suitable for children aged 5 to 7. The umbrella cover is smaller than the umbrella for children, and the material is soft to protect the skin of small hands;
3. Children's Umbrella: This kind of umbrella is very small, and its purpose is not only to shelter adults from the wind and rain, but also to be used for entertainment, and its practical use is not great.
Generally, there are maple leaf umbrellas and cartoon umbrellas. In the market, it is equipped with various models. This photo frame greatly attracted the children's curiosity. So as to occupy this part of the umbrella market.
Parachute paraglider
Paragliding originated from 1984. It is a flying sport invented by a group of French pilots who love skydiving and hang gliding. It is very popular in Europe, America, Japan and other countries, and it has also set off a whirlwind in Taiwan Province Province. Paragliders are different from traditional parachutes. This is an airplane. About 20 years ago, Beden, a French mountaineer who lived in Chamonix at the foot of the Alps, successfully flew from the Alps to the foot of the mountain with a square parachute. Many mountaineers have followed suit and further improved parachutes, combining the characteristics of parachutes and paragliders, to create paragliders that can take off on hillside terrain and soar freely in the air. 1984 French mountaineer Philon successfully flew over Mont Blanc in the Alps.
paraglider
Paragliding is famous and popular all over the world. Today, there are thousands of paragliders around the world. Paragliding itself has no power. Apart from the special shape (flying wing) of the umbrella when it is inflated, it is controlled by the pilot and combined with various characteristics (aerodynamic force) in the atmosphere. Traditional parachutes, that is, ordinary parachutes, can only produce descending resistance in the air without lift, while paragliders will produce speed and lift in the process of flying in the air, which is much greater than the resistance. Because structurally, the internal structure of the paraglider is provided with airbags, before inflation, the paraglider has no substantial edges and corners, and once the internal airbags are inflated, the front edge of the paraglider will have edges and corners. In this way, when the paraglider flies in the air, the relative airflow is divided from the upper and lower sides of the wing, and the resistance is parallel to the other side's wind, and the weight is combined with the air above the wing, so that the paraglider moves forward at a certain speed.
Umbrella golf umbrella
Tri-fold umbrella
The most common golf umbrellas are straight hand-held golf umbrellas, straight automatic golf umbrellas, and 20% self-opening golf umbrellas. Because the umbrella is very big, they tend to go for a ride. After a strong wind, the weaker ones tend to be unstable. More and more humanized design has solved this problem well. Golf umbrella cover has been improved. The common practice is to make the umbrella cover into a double layer, and then the top of the umbrella cover below is empty, and then it is on the top. It's bigger than the vent and just covers it. The upper and lower layers are stitched with a small amount of needle and thread. During normal use, rainwater cannot enter the umbrella. When the wind blows, there is a surplus top row.
Tri-fold umbrella
Three-fold umbrella is a kind of rain gear. As the name implies, it is an umbrella that can be folded three times and is easy to carry. This kind of three-fold umbrella is compact in structure, strong and durable, and can be used for both sunny and rainy purposes.
19th century is the golden age of umbrella development. With the continuous progress of society, people have invented many new materials and made all kinds of portable and practical umbrellas. During this period, a three-fold umbrella appeared. With the fluctuation of international raw material prices, the profit of 30% umbrella is also challenged. How to deal with these crises? Yiwu Umbrella Industry Association actively promotes brand awareness, advocates high quality and efficiency, and improves product competitiveness.
Three-fold umbrella has experienced more than ten years of development, and a set of perfect umbrella industry system has been established from raw material suppliers, manufacturers and sellers, gradually improving the comprehensive competitiveness of folding umbrellas in the umbrella industry and seeking greater development space.
Multi-fold umbrella
A multi-fold umbrella comprises a central pole (1), an upper nest (2) fixed at the top of the central pole (1), a lower nest (3) slidably sleeved with the central pole (1), and a plurality of umbrella ribs (5) supporting an umbrella surface (8); The umbrella surface (8) is an umbrella surface with unequal widths, that is, the distance between the front edge of the umbrella surface and the central rod (1) is small, and the distance between the rear edge of the umbrella surface and the central rod (1) is large; Accordingly, the umbrella rib (5) includes a front umbrella rib (53), two side umbrella ribs (52) and a rear umbrella rib (5 1), wherein the front umbrella rib (53) has fewer wrinkles and the rear umbrella rib (5 1) has more wrinkles. The rear part of the multi-fold umbrella of the utility model has a large shielding area, which can prevent people's back from getting wet when it rains heavily, and has good front sight and windproof effect.

Umbrella pencil umbrella
pencil umbrella
The keel of the pencil umbrella is pencil thick, which is very suitable. In terms of color, pencils such as colored lead and crayons are bright and fresh. Umbrellas, too, want to give people the feeling that they are colorful, like a box of colored lead, full of childlike and lovely taste, which makes people fondle it. For example, the color of "needle" has no such impression in people's minds. The weather is cold and sunny. If this is the first impression, it is estimated that no one wants it.

Umbrella sun umbrella
Design description:
The solar umbrella inflatable airplane consists of a paraglider, a solar cell, a propeller, a brushless motor and a control part. The reason why paragliders are modified instead of designing solar-powered planes is around 200 1. Americans have applied for a patent for solar-powered aircraft in China. In order not to infringe, it is possible to fly at a low speed because the energy of solar cells can't make the plane fly at a high speed for a long time (such as the solar plane in the United States), and considering that the inflatable paraglider has good unpowered gliding ability and is lighter than the wing with the same volume.
Implementation scheme:
Fill the paraglider with air (modification) (seal the air inlet at the front end and install the airbag with corresponding shape) to keep its shape unchanged. 2. On the upper surface of the inflatable paraglider, a propeller, a brushless motor, a remote controller (not used for carrying people), a solar cell, etc. are installed through a bracket to make an unmanned remote control solar paraglider.
Second, innovation:
1. Paragliders used as wings can reduce weight (the volume ratio is the same as other materials), and can also overcome the original and collapse phenomena of paragliders. And has strong bending resistance.
2. Its flight safety is extremely high. Because it is an inflatable paraglider, the flight speed is slow and the stall speed is low, so even if you lose power in the air, you can make a paraglider-style safe landing. This is also a safety advantage over other aircraft.
3. The flight time is long, because it is powered by solar energy. Theoretically, it can fly continuously for at least one night, several weeks or even longer.
4. Use the excellent low-speed unpowered gliding ability of paraglider. (The flight record of paraglider is 17 hours)
5. Convert solar energy into electric energy to make the plane fly, realize environmental protection and no pollution, and do not consume the existing traditional energy.
6. Having their own intellectual property rights, the patent of solar plane applied by Americans in China is not infringing.
Third, the application prospect:
Aviation reconnaissance, communication, advertising aerial photography, fire monitoring, environmental monitoring, remote sensing measurement, etc.
The United States, Israel, Japan and other countries are actively developing research on solar-powered aircraft.
Umbrella space umbrella
Space umbrella is an umbrella-shaped object that can be unfolded in space, with a diameter of several meters and tens of meters and a thickness of several microns and tens of microns.
In order to deal with the enemy's multi-spectral detection, the surface of the space umbrella is coated with anti-infrared and visible light coatings. There are many specifications for the diameter of space umbrella, generally 5- 10 meter is appropriate; Space umbrellas are usually put in rotating umbrella bags. When the umbrella bag enters space, the micro nozzle starts to rotate, and the space umbrella is unfolded under the corresponding centrifugal force. Because the mass and folded volume of the space umbrella are very small, the mass and volume of the umbrella bag can also be made very small (the diameter of the umbrella bag can be tens of centimeters and the mass can be hundreds of grams).
I hope it can help you solve the problem.
