Hydrophilic Jellyfish Granules: A powerful additive for enhancing the hydrophilicity of materials!
In the application of polymer materials, hydrophilicity is often an important performance indicator. As a functional additive, hydrophilic water particles can effectively improve the surface properties of materials such as plastics and fibers, endowing originally hydrophobic materials with certain hydrophilic capabilities, and play a unique role in multiple fields.
The working principle of jellyfish granules is based on their special composition. It is mainly composed of carrier resin, hydrophilic additives and dispersants. Hydrophilic additives are mostly compounds containing polar groups, which have a good affinity for water molecules. When hydrophilic water particles are added to the substrate, during the material forming or processing, the hydrophilic additives will gradually migrate to the material surface, forming a film with hydrophilic properties. This film can reduce the contact Angle between the material surface and water, making it easier for water to spread and penetrate the material surface, thereby enhancing the hydrophilicity of the material.
The selection of carrier resin should be compatible with the modified substrate. If it is used for polypropylene materials, polypropylene resin is usually selected as the carrier. For polyester fibers, polyester will be used as the carrier. This compatibility ensures that the hydrophilic jellyfish particles can be evenly mixed with the substrate, avoiding compatibility issues that could affect the mechanical properties of the material. The function of the dispersant is to promote the uniform distribution of hydrophilic additives in the carrier, prevent additive agglomeration, and ensure the consistency of the modification effect.
The application scenarios of hydrophilic jellyfish particles are mainly concentrated in fields where there are requirements for the hydrophilicity of materials. In the fiber industry, synthetic fibers such as polyester and polypropylene are inherently hydrophobic, and the fabrics made from them tend to cause a stuffy and hot feeling when worn. After adding hydrophilic water particles, the hydrophilic groups on the surface of the fibers can adsorb moisture in the air, take away heat through evaporation, improve the moisture absorption and sweat-wicking performance of the fabric, and make it more comfortable to wear. This type of modified fiber is often used in the production of close-fitting clothing such as sportswear and underwear.
In the field of packaging, hydrophilic jellyfish particles can be used for the modification of food packaging films. Ordinary plastic packaging film has a relatively strong moisture barrier property, but some fresh foods require moderate air permeability and moisture absorption to maintain freshness. The packaging film with added hydrophilic water particles can regulate water transfer, preventing food from losing too much water and shriveled, and avoiding mold due to the accumulation of moisture, thus extending the freshness period of food.
In the industrial field, hydrophilic particle modified plastics can be used to make filter materials. Hydrophilic filter membranes can better contact water-based liquids, improve filtration efficiency, and are suitable for scenarios such as water treatment and liquid medicine filtration. In addition, adding hydrophilic particles to agricultural films can make it easier for the film surface to adsorb dew, forming water droplets that seep into the soil, providing moisture for crop growth. At the same time, it can reduce the condensation of fog on the film surface and improve the light transmittance.
When using hydrophilic jelly granules, the addition ratio should be controlled according to the specific use of the material. The addition amount is too small, and the improvement effect of hydrophilicity is not obvious. If too much is added, it may affect the original properties of the base material, such as causing a decrease in the toughness of the plastic and a reduction in the strength of the fibers. Meanwhile, the processing temperature and time will also affect the effect of hydrophilic water particles. The optimal process parameters need to be determined through experiments to ensure that the hydrophilic additives can uniformly migrate to the material surface.
Although the hydrophilic jellyfish particles do not change the basic structure of the material, they endow the material with new properties through surface modification. It solves many problems caused by the hydrophobicity of polymer materials in a simple and convenient way, providing an economical and effective solution for the functional expansion of materials, and has become an indispensable additive in the field of polymer material modification.
