Fan Zhendong won, but Li Ning lost.

  Morita lost, but Uniqlo won.

  Dong Ge, who is completely wet, VS Xiao Mo, who is dry and comfortable, the difference is clear at a glance.

A few days ago, I wrote a brief comment about the wet jersey from the match between Fan Zhendong and Zhang Ben Zhيه. I didn't expect it to receive so much attention.

Let's continue talking about jerseys tonight. Please manually click for the previous context to save space.

  Before we talk about today's jerseys, did everyone watch last night's women's singles final?

The Li Ning competition outfits of the same series, in the first two games, Chen Meng and Sun Yingsha were constantly adjusting the right sleeve of their shirts. Why is this so.

  1. Sweating a lot, it sticks, feels uncomfortable, affects performance.

  2. Professional habit. Used to it.

  You choose one?

Here are just screenshots taken randomly from the first and second rounds, and starting from the second round, the frequency of rolling up the sleeves increased significantly.

  Then until the end of the match, both sides couldn't stop rolling up their sleeves.

  The frequency is so high that I want to write this answer today.

Table tennis sport, for the main deformation areas of clothing, for right-handed players,

  Concentrated in the upper right shoulder, upper right arm, back of the right shoulder, and under the armpit.

  Therefore, the treatment of the sleeves is particularly important.

  In fact, the simplest solution is to make it sleeveless.

And this plan was also tried during Kong Linghui's era. However, it was generally rejected by the female team members, who were afraid of exposing themselves.

From the match, it can be seen that players who are used to diving left and right with large movements still feel somewhat shy and uncomfortable. Some players even subconsciously make gestures to protect their collar. Many players lack confidence in their figures, and 范瑛 once complained to Kong Linghui that she was too fat and didn't look good in a skirt. Although Kong Linghui comforted her by saying, "You are much stronger than Serena Williams," it still makes people feel that the players' confidence on the court in skirts has decreased.

Ding Ning seemed a bit hesitant when asked, "If you could choose your own clothing, would you choose shorts or a skirt?" "Uh, hahaha, well, I still need to get used to wearing skirts, especially during training, so that I can feel better during competitions. Currently, there are not many female table tennis players who wear skirts, so there aren't many such outfits available. I hope that in the future, sponsors can tailor some for us, and I hope the outside world can see a different side of us."

Regarding the players' concerns, Kong Linghui stated that he will communicate with the clothing company, and for next year's World Table Tennis Championships, they will customize some dresses, aiming to make the outfits more innovative and better suited to the players' body types. For the off-shoulder style that many players find uncomfortable, Kong Linghui also indicated that it will be discontinued, not for aesthetic reasons, but to leave space for sponsors' advertisements, which requires sleeves.

By the way, this year the YY badminton team next door provided two types of jerseys to choose from: sleeveless and short-sleeved, available for free selection.

For example, the women's doubles badminton silver medalists Sheng Tan duo wore sleeveless outfits.

After all, short sleeves can also be used to wipe sweat. Without sleeves, you can't wipe sweat anytime and anywhere, and you might not get used to it.

Speaking of table tennis uniforms, Li Ning's competition uniform mentioned in the previous answer is made using 75D+30D or 75D+20D CLEANCOOLspandex wrapped yarn. To put it simply, this means it has high elasticity and is a fitted style.

After years of modifications, considering the characteristics of table tennis, the current design direction of the national team's clothing sponsor is to create elastic, body-hugging styles. The current national team competition uniforms mainly feature short-sleeved, body-hugging designs.

But if the clothing is too tight, it can cause a problem where sweat makes the clothes stick to the skin. For example, in the final match between Chen Meng and Sun Yingsha, they frequently pulled at their sleeves because the clothes stuck to their skin, making them uncomfortable.

  Therefore, the design of the armhole is particularly important.

  Let's take a look at the tailoring of the two outfits in tonight's men's singles final.

Li Ning's piece of clothing, to maintain the integrity of the large front print, chose a front continuous sleeve panel design. The front piece extends all the way to the back shoulder. A triangular gusset is made at the back shoulder. The side uses a separate piece for the lower part of the sleeve (green circle in the image below).

  The color scheme in the following image can make the division of the pattern pieces clearer

  This short stitch line, we call it a dart.

Common techniques in modern clothing, especially in women's wear. For example, the seam below the chest on a strapless dress is called a bust dart. Depending on where it is placed, it is generally called an XX dart.

Because fabric is flat, using darts can save material and reduce the process of cutting and sewing to better fit the body.

Li Ning's one-piece front design, which covers from the chest to the back of the shoulders, will definitely have a problem with not fitting well. Although the N in CHINA will be sewn into the dart, he must still add a shoulder dart.

Just with this small provincial road, it cannot achieve a very perfect fit for the shoulders.

  But today, Morgard showed me a better solution.

He hardly rolled up his sleeves all night. Occasionally, he would roll up his left sleeve. A right-handed player.

This Uniqlo jersey, which looks simple, seems to have solved this problem well.

The green part in the following image is the sleeve pattern piece. There is no separate pattern piece for the side, and the complete armhole is shaped with a dart at the back seam.

Ignoring the seam in the center of the back, it perfectly divides the garment into three complete major sections: the shoulder and sleeve part, the front piece, and the back piece.

This cutting method makes the shoulder part of the clothes fit the body better, rather than the skin.

The design of this piece of clothing, supported from the shoulder, results in a larger underarm space and reduces the area of the garment that is close-fitting.

In addition to being conducted to clothing and then evaporating, maintaining a reasonable space between the skin and clothing is also beneficial for sweat evaporation.

This is also one of the reasons why overly tight styles have poorer moisture-wicking and breathability compared to looser designs.

  This Uniqlo design is very suitable for clothing that allows for high-frequency shoulder and arm movements.

  If there's no patent, I suggest all sports brands copy it.

  After talking about the sleeves, let's get back to the moisture-wicking itself.

Although Fan Zhendong didn't really roll up his sleeves, because they were completely soaked with sweat, rolling them up would be useless

I mentioned in the previous related answer that the problem is most likely with the CLEANCOOL yarn.

This is a yarn that primarily focuses on antibacterial properties. However, it also has moisture-wicking and sweat-dispersing functions. Unfortunately, its patent page only briefly mentions the moisture-wicking and sweat-dispersing functions.

The moisture absorption and sweat-wicking test for textiles in our country is not a mandatory testing standard; at most, it is categorized into different levels.

Li Ning's this competition suit indeed has moisture-wicking properties. It is very clear that the moisture-wicking is excellent, but the sweat-drying performance is very poor.

Moisture-wicking is a two-step process: first, it absorbs sweat from the skin to the fabric, transferring it unidirectionally from the inner layer of the clothing to the outer layer. Then, through natural evaporation, the sweat is released into the air.

From the official website of the yarn, it can be seen that his yarn design includes a similar cross-shaped four-channel design for the polyester part, akin to Coolmax.

The principle of this fiber design is to increase the heat dissipation area of the fiber, thereby achieving the purpose of faster water evaporation.

But I personally think that there might be two factors affecting his quick-drying performance. Since I haven't seen the actual item, this is purely theoretical analysis. I don't want to be too sure:

The first is the silver-based antimicrobial agent. According to the introduction, it is added during the production of the yarn, which differs from the traditional method of adding auxiliary agents during post-processing, making it less likely to detach from the yarn and penetrate the skin.

But the issue is that the addition of silver ions may fill the gaps in the fibers, reducing the heat dissipation area.

The second is spandex-covered yarn, where polyester fibers cover spandex fibers. This also reduces the heat dissipation area.

Spandex covered yarn is formed by wrapping long filament or short fiber yarn in a spiral manner around spandex yarn in an elongated state, creating elastic yarn.

For those with a tendency to sweat profusely, clothes become saturated with water and are even harder to evaporate. The solution is quite simple.

  Today Uniqlo has demonstrated to us once again:

  Thicken.

  What a simple principle. Thicken it, and you can absorb more water.

This Uniqlo clothing item is currently not searchable on the official website. However, no matter how you look at it, it doesn’t seem like the normal AIRism quick-dry shirt we can buy; that thing is really too thin, and every time I wear it, it shows through.

Due to the lack of information, the fabric yarn technology of this Uniqlo quick-dry shirt cannot be determined, but from its actual performance, the moisture-wicking and quick-drying properties are excellent.

The entire match ended, and under the condition that neither side changed their clothes, Morlega's shirt was only wet in a large triangle on the back.

  No pattern, simple and plain, but effective.

A casual wear brand has actually made such a moisture-wicking jersey. I'm pleasantly surprised. Old sportswear brands, step up your game.

  Hope this gets released for sale soon, must buy.

  Unexpectedly hot update:

Everyone, let's have a rational discussion. I have no intention of criticizing all of Li Ning's products; I am just analyzing this particular model.

Any brand, different models, workmanship, and materials may all be different. The same model, different batches, may also change the fabric and process.

For example, the Singapore badminton team's uniforms sponsored by Li Ning use regular ATDRY without antibacterial properties. That version is cheaper, but it seems to perform better. So, let's focus the discussion on this specific model and not generalize to criticize the entire brand. Thank you.

  Additionally, I will address some of the more common questions:

• 
  Q: Most prints are by flexography, coatings, which can lead to poor breathability.

A: This must be wrong. This style is made of polyester material, and large-scale prints are definitely prioritized with digital dispersion transfer printing or dispersion direct spray. Flexographic printing is only suitable for small-area logos and other patterns. It is indeed not breathable, but it is not the technique used for this Li Ning garment. (Supplement: After re-examining the enlarged images of the garment, it was found that the brand logo and some line accents used flexographic printing, but the area is small and can be ignored)

Between the two, the transfer printing is more likely. The pattern on this competition outfit is definitely made using positioned piece printing, which is currently a very mature printing technique.

The advantage of transfer printing is that the weft skew is easier to control, and the prints are less likely to be misaligned, making it easier to cut. After being pressed, the fibers on the surface of the fabric will be flattened and compacted, reducing the moisture-wicking and sweat-releasing performance. At the same time, after polyester material is pressed, the surface will have more luster. This is more in line with my judgment of the printing process for this piece of clothing.

Another method is the dispersed direct injection process, which has the disadvantage of high cost and a relatively high rate of defective products. Its advantage is good penetration, allowing some color to be visible on the reverse side. It is currently mainly used in areas such as scarves, where patterns need to be visible on both sides. Moreover, after printing, it is not completed in one step; it still requires color development and water setting. Although this does not affect the moisture-wicking and quick-drying properties, it is more difficult to control the skew in large areas of positioned printing, leading to a high rate of fabric correction in finished garments.

• 
  Q: Fan Zhendong has a sweaty constitution, so we should control the variables to analyze the moisture-wicking properties of this clothing.

A: I never denied that he has a tendency to sweat a lot, but this does not contradict the inference I provided. Excessive sweating and poor moisture-wicking of the clothes can coexist. As for controlling variables, the conditions were limited, so please understand.

•   Q: Don't draw conclusions without data support.

A: Inference and conclusion are different. I used many bold "possibilities" in my article irresponsibly, just to remind everyone that this is merely an analytical inference based on my professional experience and knowledge of textile theory, and I do not guarantee its correctness.

•   Q: Uniqlo soft advertising?

  A: Uniqlo, send the money! Help me contact them, thanks.

  Subsequently, as a supplement to this response:

  Why do the female table tennis players of the national team like to pull up their sleeves so much.
