1. What are the fabrics of outdoor down jackets

1. waterproof coating (membrane) fabric

This kind of fabric is a bit similar to the assault fabric and has the performance of waterproof and humidity. It is generally used in high -mountain down jackets.But the difference is that the fabric will be lighter and softer than the fabric of the jacket.In addition, because down jackets are generally used in cold environments, they are mainly targeted at the melting water of solid water in ice and snow. Therefore, the requirements of the water resistance of the fabric will not be as high as the jacket.Glossom.

2. High -density waterproof fabric

The density of the fabric itself is very high, generally above 290T.Then use the high temperature to fuse the surface fabric to reduce the post -processing process of the gap of the fabric to improve the resistance.The lightness and softness of the fabric are the highest among all down jacket fabrics, while at the same time, it has windproof, water -proof and breathable performance.

3. Ordinary woven fabric

Ordinary woven fabrics and anti -velvet cloths are generally used with low density nylon or polyester. When making down jackets, anti -velvet cloths are added to the fabric, which can play a role in anti -velvet.The disadvantage is that the anti -velvet cloth affects the softness of the down jacket and increases the weight of the whole clothes.

2. How to choose outdoor down jackets

1. Fatty types

At present, the down jackets sold on the market have goose down, duck down, and duck pills and feathers mixed.The warmth of goose down is the best. The secondary duck hair, the worst of mixed feathers (usually we do not buy this mixed feathers down jacket in outdoor activities).Duck down jackets have a certain duck flavor. If you are allergic or disgusted with duck down, you can buy goose down. There is no smell of goose down.

2. Fill

This is the hard indicator of down jackets and an important parameter for the warm effect of down jackets.Generally speaking, users with low altitude climbing or basic snow mountain climbing do not have to buy a lot of charging velvet. Generally, they can be used as a suplodes or duck down with a volume of about 120g.If you go to the northeast or high altitude blood line activity in winter, the requirements for charging volume are relatively high, especially under high -altitude snow line activities, many down jackets use a conjoined situation for shrinking.At this time, the charging volume must be selected according to the temperature at that time.

3, fluffy

The fluffyness is a universal indicator used to measure the warmth of down jackets internationally. It refers to the value of the volume cubic inch of the volume without any external force under certain conditions.The space of the ode is 600 cubic inch, which is called the fluffyness of the down.In the case of a small amount of charging, the higher the number of puffs, the better the warmth performance.Because the higher the fluffyness, the more thermal insulation air contains, the better the thermal insulation performance, that is, it has better warmth.The general price of down jacket is about 450-500, and the slightly higher down jacket, the fluffyness can reach 600-900.

4, down jacket material

There is a down jacket to keep warm. To maintain the body temperature of the down jacket, you must eliminate the communication with the cold air from the outside world. Therefore, the windproofness of the down jacket must be done.Wind irrigation into it will affect the actual warmth effect.There are also some down jackets in the extremely cold area that may add plush to reduce temperature communication inside and outside the down jacket.In addition to windproof treatment, the basic waterproofness of down jackets cannot be ignored in the case of changing Outdoor environments. If the down is drooling due to wetness, the down thermal insulation effect is indexed.Therefore, the waterproof of outdoor down jackets cannot be underestimated.

3. How much is Outdoor down jacket?

The price range of outdoor down jackets is roughly between hundreds and thousands of yuan, and the specific price depends on factors such as brands, materials, design and functions.

Different brands and styles of outdoor down jackets are relatively different.For example, the price of outdoor down jackets of high -end brands is usually between 2,000 and 10,000 yuan, while some cost -effective Outdoor down jacket brands are less than 1,000 yuan.

Factors affecting outdoor down jackets include brands, materials, design and functions.High -end brands of down jackets usually use high -quality goose down or duck down. The design also pays more attention to thermal and functional, so the price is higher.Some cost -effective brands provide options with more affordable prices through optimization costs and design.

1. What material is good for surfing board

surfing plates are generally made of glass fiber and carbon fiber. Now high -end surfing boards are more popular with carbon fiber materials. The reasons are as follows:

1. Light weight.The weight of the carbon fiber is a quarter of the steel, which is lighter than glass fiber. Ordinary glass fiber Surfboards are about 15 kg. People who go to the sea will naturally want the lighter the weight.question.

2. High intensity.The intensity of carbon fiber is 4 times that of steel. As we all know, the impact of the waves is very large. If the strength of the surfing board is too low, once the force is damaged, not only can it be experienced to get the fun of exercise, but it will also threaten people's personal safety.Essence

3. Corrosion resistance.In addition to oxygen and hydrogen in the seawater, there are chemical factors such as CL, NA, MG, S, CA, K, and BR, which are alkaline.The surfing board is soaked in seawater for a long time, which will be corroded.The chemical properties of carbon fiber are stable, with acid and alkali, corrosion resistance, aging resistance, and long service life.

4. Good balance.surfing in the sea, its own control technology is very important, and the balance of surfing board is also important.The carbon fiber has a strong Earthquake resistance and good balance. People stand on it, which is not much different from standing on the ground.

5. The design is clever.The carbon fiber waveboard is personalized and customized, which can be designed as a variety of styles to meet the needs of different users.For example, folding, combined, long boards, short boards, gun versions, soft boards, floating plates, Paddle boards, etc.

2. What is the size of the surfing board?

The surfing board was about 5 meters long and weighing 50 to 60 kg.After the Second World War, a foam plastic board appeared, and the shape of the board was also improved.The surfing board is 1.5 to 2.7 meters long, about 60 cm wide, 7 to 10 cm thick, flat and flat, the front and rear ends are slightly narrow, and there is a stable tail fin at the rear.In order to increase friction, there is a waxy outer membrane on the board.The weight of all surfing boards is only 11 to 26 kg.

1. Is it necessary to wear a Compressed jacket?

Do I have to wear a Compressed jacket during exercise?The answer may be negative.

First of all, short -term and low -intensity exercises do not need to wear compressed jackets. The price of compression clothes is expensive and complicated. There is no need to do it for a low -intensity exercise.

In addition, exercise for the purpose of exercise does not have to wear a Compressed jacket.Although the Compressed jacket can make the body comfortable and effort during exercise, it cannot provide us with better exercise effects.When the exercise strength is controllable and there is no sunscreen, the compression coat is not necessary.

On the other hand, if you want to perform high -intensity exercises in high -ultraviolet or high -thermal environment, it will be particularly important to have Compressed clothes with sunscreen, heat dissipation, sweating, and tight -fitting function.In this case, compressing clothes can not only make us stronger, but also provide us with better protection.

two,How to choose a Compressed jacket

1. Look at the selection of materials

Only good materials can make good compression clothes.

A good Compressed jacket consists of more spandex, which is better elastic and wear -resistant. It can withstand tens of thousands of friction without tearing.It also contains a special high -stretching and elastic memory material, allowing the Compressed jacket to restore the original state no matter how pulling it through.Therefore, the life span of the Compressed jacket is longer, and it can have the original sense of pressure after a long period of time.

2. Picking the woven process

With advanced weaving technology, high -strength pressure can be guaranteed.

The Compressed jacket uses a variety of high -quality yarns for multiple reinforcement knitting fabrics, with hybrid fiber to ensure its high elasticity and strong pressure, which can make the Compressed jacket better recover, and always maintain high pressure.Compared with the traditional cylindrical knitting method, this processing method is much better.

3. Look at the gradient pressure design

There is no efficacy like tight -fitting full -binding pressure.

Because the compression intensity required by the human body during the blood reflux is different, a good compressed coat will apply gradient pressure to a specific part of the body, so that the blood flow can be better promoted.And the pressure near the heart is weak. This gradual, targeted pressure design can accelerate the body's processing of lactic acid and other metabolic wastes, and to provide more oxygen and energy for muscles. This allows the athletes to longer be longerMaintain more efficient time.

4. Multiple function design

Multi -product function design makes compression clothes more practical.

Some fabrics used in some compressed jackets also have antibacterial and anticidal effects. The body will have a lot of sweat during exercise. Good sweating can make exercise more comfortable, and effectively sweat can inhibit bacteria, make the Compressed jacket more safer to wear it to wear.,health.

1. The service life of table tennis shoes

The life of table tennis shoes will be affected by various factors, including frequency, venue conditions, shoes quality, and personal playing habits.

Under normal circumstances, the average life of a pair of table tennis shoes is about one year.This is because the instability of table tennis caused the shoes to continue to jump left and right, which may cause loss.However, if the shoes are excellent, the production process is fine, and the golfers can properly maintain and rotate, the life of table tennis shoes may be longer.

In order to extend the service life of table tennis shoes, regular inspections and cleaning shoes are recommended to avoid use under harsh field conditions and appropriate rotation to avoid the same pair of shoes for too long.

2. How to wash table tennis shoes

The previous article has simply understood the regular cleaning shoes, which can extend the service life of table tennis shoes. So how to clean the specific table tennis shoes?

In terms of cleaning, for how to clean the table tennis shoes, it is recommended that you use a soft hair toothbrush to gently brush lightly. The time should not be too long. After brushing, you should use warm water or cold water in timeTime.

After washing, wipe the remaining water immediately with a dry rag. If the cleaning shoes are visible to the air cushion, the water around the air cushion is cleaned after the above processes are completed, so as not to make some glue that can be decomposed by some water time in the water time.Chemical changes cause gum.

If possible, use a toothpick to remove the small stone that is sandwiched during walking in the soles of the shoe. Because it is pinched for a long time, it will deform the soles of the shoe, which will affect the braking performance of the shoe to a certain extent.

3. Introduction to the maintenance method of table tennis shoes

1. clean in time after use:table tennis shoes should be wiped in time after exercise to wipe the upper and soles with a wet cloth, and sweat and dustclean and place it in a ventilated place.

2. clean regularly:Regular (one to two weeks) use professional shoes cleaner to completely clean table tennis shoes, do not use alkaliclean the shoes with a strong or acidic cleaner, which will damage the material of the shoes.

3. clean the clear frictional surface:The frictional surface of table tennis shoes is easily contaminated by dust. It should be used with clean wet cloth orThe toothbrush cleans the dust of the frictional surface.

4. Regular maintenance:After using table tennis shoes for a while, the shoes should be maintained regularly. You can use professional shoes.maintenance oil or shoe protective agents are treated to keep the shoes bright and soft.

5. Pay attention when storing:table tennis shoes should be avoided in the sun and high -temperature environment when storing, which will damageThe soles and upper materials of the shoes are best placed in a cool and ventilated place.

1. What does it mean to float and water

During fishing, especially when fishing, many friends encountered the situation of floating and water. The so -called floating drifting water, also called drift, refers to natural factors such as flowing water, wind and other natural factors.Under the subjective factors, the vertical state in the water body was broken, and the impact of storms and waves broke the original balance state to make it slightly moved, and then the original dazzling was eaten by the water body or all of them or all of the all.One phenomenon.

Second, what is the reason for Fish drifting water

If the fish drifts away, the fishing line will become curved lightly. The sensitivity of the fishing group will be reduced.What is the reason for this situation?

Generally speaking, the Fish drift water is mainly due to two reasons. One is caused by wind. The weight of the float is relatively small. Under the influence of wind and water, floats will move in the water; another reason is that the water is caused by waterThe water flow is too large, and the flowing water will cause thrust on the float, causing the float to drift downstream of the water.

3. How to solve the fishing floating and drifting water

When the phenomenon of floating water occurs, whether it is fishing or fishing, it is very unfavorable to our fishing. It directly affects our floating drift and dens.So how to solve this situation?

1. Floating and gently walking water

The water flow is slow, the wind and waves are not large, and the floating drift is light. This kind of water is the most common and the best. Generally, it is mostly used to change the fishing layer and float method, bait status, and floating lead.Method processing:

(1) Change the fishing floating to the bottom of the fishing, let the bait touch the bottom, and to prevent the floating water through the friction of the bait and the bottom of the water.

(2) Moisture high fishing and low fishing to lower the fishing high, let the double bait lie down, and increase the friction between the bait and the bottom of the water by aggravating the lead Skin and the bottom of the water.

(3) Change to eat a large amount of lead, and reduce the phenomenon of floating water through the self -weight of lead pendants.

(4) Change the bait to rub the bait, and prevent the floating water from drifting by changing the bait weight and friction with the bottom of the water.

2. Floating moderate water

When the floating water is powerful, the four methods mentioned above are not great. At this time, you need to make the dullness of the fishing. Pull the float through the weight of the lead pendant to prevent the floating water from walking in water.Generally, large drifts are used, which makes lead on the buoyancy of drifting.Common methods include lead fishing, lead fishing, and double lead fishing.

3. Drinking heavy water

When the water flows is turbulent, the wind and waves are too large, and the floating water is severe, at this time, due to the fast water, the float will flood.No matter how blunt fishing, how high the number of meters is revealed, it will be quickly drowned in the water, which is often said that the "flooding" is serious.

At this time, the above methods will not have a good fishing effect, and even the unable to fish. The only way is to stretch the method of fishing.Use the large lead pendant fishing to run and run the pole when throwing the pole. The tip of the pole is from the water to a certain distance, so that the pole tip and the line group have a certain linear angle. By observing the Hiking of the pole tipThe timing of the pole.
