Heat Preservation And Heating Fiber Research And Development Space Is Very Large, New Type Of Warmth, Self Heating.

The warm acrylic fiber produced by the group and other enterprises has ignited the enthusiasm of the downstream enterprises for the light thermal underwear.

This is also the embodiment of the consumption trend of clothing warming up in recent years.

At the links of acrylic fiber products held by Jilin chemical fiber group, many downstream enterprises have a bright prospect in this field.

Acrylic, polyester, viscose, etc.

Blended yarn is becoming a popular material at home and abroad.

At the same time, some polyester and viscose manufacturers have also developed and upgraded their original products to make breakthroughs in thermal performance.

A variety of warm materials, starting from a variety of mechanisms, have a more satisfactory thermal effect. Some keep warm while they also have the function of moisture absorption, so that clothing becomes the "air-conditioning" of regulating temperature. These are the wisdom of fiber research and development personnel.

Traditional upgrading function is stable

R & D space is also very large, not only to achieve breakthroughs in the new field, but also to upgrade in the original field.

For example, to achieve the replacement of down.

Last year, Jiangsu Yizheng chemical fiber production Yi Zhen products were officially put on the market.

Yi Zhen velvet product is a new type of pearl cotton product developed by downstream users, led by the synthetic fiber Department of Chemical Sales East China branch, and jointly developed by Yizheng chemical fiber and Changshu Jinyu. It is mainly used for filling high-end clothing and toys.

The pearl ball made of special production technology is full of granules, soft and smooth in hand, and far superior to ordinary pearl cotton products.

After filling, the product has good dispersibility, and the effect of rebound is better. To some extent, it has reached the feel and substitution effect of natural down.

The added value of the product is relatively high, and the price per ton is higher than that of Yizheng chemical fiber company.

Infrared thermal storage fiber is also a good material for making warm textiles.

Infrared thermal storage fiber mainly uses its sunlight and lights at any time to absorb the environment, and the human body's life hotline to store heat so as to achieve the purpose of thermal insulation. Therefore, infrared thermal storage and thermal insulation are long lasting, and there will be no feeling of being hot and cold. This is very suitable for making thermal clothing.

Corresponding to this is the hygroscopic and heating fibers. The main principle of the fiber is to absorb the vapour in the gaseous state and turn it into liquid so as to pform its kinetic energy into heat energy and make the fabric heat. But when the moisture absorption of the fabric is saturated, when the liquid liquid becomes vaporized, it needs to absorb heat and make the fabric cool.

Therefore, moisture absorption and heating is not a long time heating process.

In the process of dyeing and finishing of concrete spinning, attention should be paid to the damage of phase change materials (microcapsules) that absorb moisture and heating fibers. As far as possible, the temperature, time and frequency of dyeing and finishing can be reduced as much as possible, otherwise, the damage of phase change materials will be caused.

In addition, moisture absorption and heating fabrics are not easy to store for a long time. During use, the number of times of moisture absorption and evaporation can be reduced to reduce the damage of phase change materials.

New warmth and self heating

In fact, the early warming and heating functional fiber is to add far-infrared ceramic particles into the yarn, and then make ceramic particles attached to the yarns to achieve warmth retention effect after processing.

Unitika Fibers has recently upgraded this technology. The newly developed thermal storage and moisturizing fiber material Thermotron can absorb sunlight and convert the absorbed light energy into heat energy, and also has the function of reflecting the far-infrared rays emitted by the human body.

Through the "absorption heat pfer" and "thermal reflection mechanism", the body can obtain the comfortable and warm temperature needed.

The core of each single fiber is dissolving with small particles of zirconium carbide. It emits heat under the action of solar thermal energy and reflects a long wavelength infrared ray, which makes the interior of the garment warm.

The fiber material was mainly used in ski suit when it came out.

It is worth mentioning that some companies also make the natural ore from the seabed or volcanic eruption into powder, and then add fabric fibers, which can produce far infrared rays and play a role of warmth retention.

For example, Ttiumph's fluffy thermal underwear is to add natural mineral ingredients into the fiber, which is characterized by a soft wearing sensation and good thermal insulation by absorbing far infrared rays.

In addition, the underwear is made of fine fiber and fine acrylic and fuzzing materials, and the soft and smooth wearing feeling is obtained.

This kind of underwear is made of fuzzing material, which makes people feel warm from appearance.

Jilin chemical fiber group has made great progress in the research and development of thermal insulation materials. In the downstream cooperation, they create their own combination of various kinds of warm products, such as reclaimed acrylic fiber + fine denier acrylic fiber + modal, regenerative acrylic fiber + Cotton + bamboo, silk vill + Tencel, and so on.

Silk weir is a phase change energy storage viscose fiber developed by Jilin chemical fiber, and Shandong Silver Eagle chemical fiber has also broken through this technology.

The company representatives of Silver Eagle chemical fiber think that the phase-change energy storage viscose fiber will shift the traditional passive thermal protection mode to the active thermostat mode, and most importantly, do not consume other energy sources.

Generally speaking, there are mainly two ways to achieve the requirement of thermal performance: one is to keep the heat as much as possible, the other is to obtain heat in some way.

The warmth retention properties of textile and clothing are affected by the following factors: fiber materials and yarns, yarn structure, fabric structure, braiding structure, post-processing and so on.

The material is related to the functional factors such as air content, skin touch, moisture absorption, moisture absorption, heat absorption, heat absorption and far-infrared radiation.

The more air is contained in fiber and yarn, the better the heat preservation effect.

The thickness of fabric made of wool and cotton fiber material is related to warmth retention, the thicker the warmth is.

The traditional heat preservation is mainly to prevent the body from dissipating heat, while the heating fiber is a new material for self heating and warm body, and its water absorbency is far more than that of other fiber varieties.

Global health and environmental protection

In recent years, the international market is also keen on the new heating fiber products developed in Japan and Taiwan and other countries and regions. The important reason is that these products are much warmer and more absorbent than other fibers.

If clothes are worn in winter, if they only focus on the insulation performance and isolate the outside air, then the body will be uncomfortable if people sweat and sweat.

If the clothing wears good water absorption, consumers will feel more comfortable even sweating.

This is the reason why many consumers like cotton products, and it is also the reason why many chemical fiber enterprises strive to research and develop cotton imitation products.

From the beginning of the heating fiber, most of the heating fibers, such as EKS fiber and new Softwarm fiber, were developed in Japan. The new type of Softwarm fiber produced by Japanese enterprises combined with the special man-made wood pulp fiber and Dongli company's advantages of super fine anti pilling acrylic fiber, has the advantages of heat, humidity, warmth, soft touch and so on.

A person's body is breathing at all times. It will emit slight moisture at any time. The new Softwarm fiber can absorb the moisture and convert it into heat through chemical reaction to achieve the function of heating.

In the new Softwarm fiber, the inherent double-layer clearance between the super fine anti pilling heating acrylic fiber and the flat viscose cross section can prevent heat loss and achieve excellent heat preservation effect.

At the same time, due to capillary phenomenon, the new Softwarm fiber excrete excess moisture, making the body in a dry state, ensuring that the comfort degree is the best.

The new Softwarm fiber yarn can now reach 64 public branches, and is suitable for producing thermal underwear, scarves and sweaters in warp knitting fields.

In addition, the popular coffee fiber in recent years has been well maintained by the market.

The coffee dregs are carbonized by ultra high temperature and pformed into coffee carbon fibers. The underwear made of coffee can keep heat and keep warm, and it is more environmentally friendly.

This coffee carbon fabric is most suitable for making thermal underwear. Such underwear is not easy to deform naturally.
