  About phase change materials
      PCM - Phase Change Material is a widely used thermal energy storage material that utilizes heat and heat release during the phase change (solid-liquid-solid) process to store and release thermal energy. Thereby achieving the purpose of controlling the ambient temperature and performing heat exchange. Phase change materials are divided into organic and inorganic categories.

 

     In the solid-liquid phase, when the solid phase change material is heated to the melting point, a phase change from solid to liquid occurs. During the melting process, the phase change material absorbs and stores a large amount of latent heat, and the temperature of the material itself remains constant. ;

 

 

 

       Microcapsule technology is a technique in which a solid or liquid is coated with a film-forming material into particles having a core-shell structure, and the obtained microparticles are called microcapsules. The preparation technology of microcapsules originated from 20 actual 50s, and developed rapidly in the mid-1970s. Microencapsulated products and processes appeared during this period. For example, drugs, enzymes, perfumes, catalysts, dyes and other products are all encapsulated in microencapsulated form.

 

 

       Phase change microcapsules borrow this technology to disperse the phase change material into spherical small particles, and then encapsulate a layer of stable shell material on the surface to form phase change microcapsules. The technique of microencapsulating phase change materials solves the problems and difficulties in the application (liquid material loss, corrosivity, volume change rate, etc.). The core material-phase change material of the phase change microcapsules is liquid when sucked, but the outer shell is still solid, so the shape of the material is still solid particles.

 

 

 

 

Definition of intelligent temperature-regulating textiles

       Smart thermostat textiles are smart textiles that respond to changes in temperature or temperature. They transcend the insulation function of traditional textiles and are a new type of material with two-way temperature regulation for the purpose of improving comfort. It is a high-tech product that combines phase change thermal storage technology (PCM) and textile finishing technology. It has the function of automatically absorbing, storing, distributing and releasing heat. It has the effect of intelligent temperature regulation and can prevent it. The human body's intense temperature changes create a comfortable temperature environment. The principle of temperature regulation is to use the phase change material containing the solid-liquid reversible conversion with the change of the ambient temperature, that is, when the ambient temperature rises, the phase change material changes from solid to liquid, and the absorbed heat is stored inside the fabric; when the temperature is lowered When the phase change material changes from a liquid state to a solid state, the stored heat is released, and the body surface temperature is maintained, so that the human body is in a comfortable state.

 

 

 

The difference between intelligent temperature-regulating textiles and traditional thermal insulation

         Traditional clothing mainly uses the characteristic of low thermal conductivity of air, and adopts the method of increasing the static air inside the fabric to avoid heat loss. The thermal insulation effect depends mainly on the thickness and density of the fabric, and its thermal insulation effect is affected by external compression and moisture. The thermal insulation mechanism of the intelligent air-conditioning fabric is a new insulation mechanism that can provide the human body with a comfortable "micro-climate environment", which can be thermally regulated rather than thermally insulated. Textiles containing phase change materials can act as a "regulator" between the human body and clothing, clothing and the external environment, regardless of the temperature rise or decrease of the external environment, buffering changes in the ambient temperature.

 

 

 

 

Smart thermostat secret

      The secret of intelligent temperature-regulating textiles that can be automatically tempered is the phase-change microcapsules (Micro-PCM) contained in the fabric. A phase change material is a substance that changes physical properties as a function of temperature and provides latent heat. In short, phase change materials can achieve the effect of storing or releasing heat through solid-liquid conversion. (When the external temperature rises to reach the melting point of the phase change material, the internal phase change material of the microcapsule melts (endothermic); when the external temperature decreases to reach the freezing point of the phase change material, the internal phase change material of the microcapsule solidifies (exothermic).) After the phase change material is processed onto the fabric by the fabric finishing technique, the fabric has the function of absorbing heat or releasing heat.

 

 

 

       Finishing process

 

 

 

 

Advantages of our company's finishing process (compared with spinning process)

1. The amount of PCM contained in the fabric is more, so the calorific value is higher and the temperature adjustment effect is better; (PCM addition amount - our company process: 15%-20%, spinning method: up to 10%.)

2, the flexibility of production is high: our company's process is not limited to mass production, and can be customized according to the needs (different PCM volume, different PCM melting point); spinning method can only be produced in large quantities;

3. Low cost: Compared with the spinning method, our company's process has lower cost and less loss.
