Uncover the mystery of stretch ratio

When we are talking about fabrics, the term "stretch ratio" may make people feel strange and curious. In fact, the stretch ratio is a measure of the ability of a material to extend by a percentage after being subjected to an external force in its original state. Simply put, it's how far the fabric can be pulled apart and then restored. This feature is very important for clothing, because it directly affects the comfort when wearing, the freedom of movement and the durability of long-term use.

The high stretch ratio means that the fabric can be deformed in a larger range without being easily damaged, and can be quickly reset after the pressure is released. This is ideal for action environments that require frequent arm or leg flexion, such as yoga pants, tights and other fitness apparel. On the contrary, low stretch ratio is more suitable for those who pursue stable support effect, such as shirt collar mouth will often add a small amount of elastic silk to keep the shape of deformation.

There are many types of elastic fabrics available on the market today, the most well-known of which is spandex (Spandex). This is a synthetic fiber, because of its excellent flexibility and strong recovery properties are widely used in a variety of clothing. Another name is Lycra, which is actually a brand name registered by DuPont, but is also commonly used to refer to all similar high-performance elastic substances in general.

In addition, there are some hybrid products, such as nylon and spandex combination of nylon spandex composite yarn. This kind of combination not only inherits the advantages of both sides-high strength and wear resistance plus good elasticity, but also the price is relatively close to the people, so it is deeply loved by manufacturers. According to different uses, you can also see cotton spandex, polyester spandex and other forms appear in daily life.

No matter what kind of elastic fabric has its unique charm. Take sportswear as an example, they rely on excellent ventilation and sweat-wicking function with proper tension control, so that people will not feel sultry and uncomfortable even if they sweat violently. For underwear products, it relies more on soft and delicate hand feeling to bring skin-like gentle care.

How to determine the appropriate stretch ratio?

It's not difficult to choose the fabric that best suits your lifestyle and personal preferences. You can first try to gently pull a small piece of sample cloth with your hand to observe whether its reaction speed and amplitude meet expectations. You can also carefully check the ingredient description table on the packaging bag to find the word "elastic. Generally speaking, if you want to obtain better adaptability and flexibility, please give priority to products containing a higher proportion of spandex; on the contrary, if you tend to be strong and durable, you may wish to reduce the requirements in this regard.

Of course, the most important thing is to make a decision based on your own life situation. If you usually like to take part in outdoor adventures or do some physical work, then obviously an outdoor jacket with good tear resistance is much more practical than anything else. However, if you are a person who often goes to and from the office, perhaps a suit skirt that is slim and tailored and not easy to wrinkle is a good idea.

Ideal for sports equipment: High-performance stretch ratio fabrics

In recent years, with the increasing popularity of national fitness awareness, more and more consumers have begun to pay attention to their own "battle robe". Especially in the professional arena, a set of functional sportswear developed by high technology is often one of the indispensable factors behind the victory. The "functionality" in this case depends to a large extent on the physical properties of the fabric itself-that is, a sufficiently high stretch ratio.

The material with ultra-high stretch ratio allows athletes to stretch their joints in all parts of the body and maximize their potential without affecting the coherence of their movements. In addition, due to the reduction of frictional resistance, long-term training is not easy to cause skin wear. There are many highly respected professional brands on the market that are constantly introducing new styles of quick-drying T-shirts, running shorts and other popular items, aiming to provide high-quality service experience for the majority of enthusiasts.

The new favorite for everyday wear: elastic fabrics that balance beauty and wear.

As can be seen from the young people dressing up everywhere in the streets, people's understanding of fashion is becoming more and more diversified. It is no longer limited to the traditional formal suit model, but boldly try to mix and match across borders to create a unique image style. At this time, those new elastic fabrics with high-quality tactile texture and avant-garde design concept have become an indispensable magic weapon in their hands.

Designers have used these new materials to create countless eye-catching works. For example, a seamless sweater on display on a famous fashion show uses a special three-dimensional knitting technology to create a fish-scale-like patchwork textured surface, which not only has the warm and thick feeling that ordinary sweaters should have, but also looks very novel and unique. There is also a mystery hidden under a seemingly ordinary Denim vest-a whole transparent TPU film area is spliced on the back, through which the internal structure can be vaguely seen, full of future science fiction colors.

Future Outlook: New Opportunities in Emerging Technologies and Environmental Concepts

Facing the severe challenges brought by global climate change, the entire textile industry is also actively exploring the road of transformation and upgrading. On the one hand, it is necessary to increase investment in research and development, devote itself to overcoming key technical problems, and develop more efficient and energy-saving production processes; on the other hand, it is to actively promote the concept of green environmental protection and advocate a new model of circular economy development. At present, many scientific research teams have invested in the development of degradable polymer projects, hoping to achieve the goal of zero waste discharge as soon as possible.

At the same time, some innovative companies have begun to put into practice. For example, the use of marine microbial extracts to prepare new bio-based synthetic rubber to replace the traditional serious consumption of petroleum resources
