Study On The Application Of Water-Based Resin In Microfiber

Short Description:

Technical problems faced by Microfiber:

1.1 lack of air permeability and moisture permeability:
After the previous treatment of super fiber leather, the surface layer and adhesive layer are treated, which leads to its air permeability and moisture permeability no longer. In general, the top resin of super fiber leather is TPU or oily PU resin, because it is easy to form a film. However, it also has some disadvantages, such as no air permeability and moisture permeability after coating. This leads to the unique performance of the super fiber being affected and no longer has advantages.

The Handle Of Super Fiber Leather Is Similar To That Of Plastic

Touch the super fiber leather with your hand, it feels like touching plastic. The leather feels very good, soft and elastic. However, since the surface of the super fiber leather needs to be newly trimmed, and there are at least two layers, the feeling people get when touching the super fiber leather is not only affected by its own material, but also affected by the finished surface. At present, the material used for the treatment of super fiber leather is mainly TPU or PU resin, which leads to the handle of the treated super fiber like plastic. Because the super fiber must use this technology, its handle is like plastic, which effectively separates the super fiber leather from the leather.

Super Fiber Products Are Not Ecological

Generally speaking, if the process of super fiber materials can be properly carried out in the process of treatment, the final products will have environmental protection characteristics. However, because the super fiber materials must be processed by the surface layer and the adhesive layer, their products are not ecological. This is because there are many toxic and harmful substances in the resin of the surface area adhesive layer, which will cause the eurochem substances to stay in the gaps of the microfiber base cloth and be difficult to be discharged during the microfiber treatment. In this way, the grade of microfiber products will be lowered, and they are not environmental friendly products, which is inconsistent with the ecological and environmental protection concept pursued by people at present, and will affect their sales.

Analysis Of The Use Of Water-Based Resins On Microfibers

The resin used in the traditional super fiber treatment causes some problems in the super fiber, which ultimately affects its sales. Therefore, countermeasures are taken to solve the problems, that is, water-based resin is applied to the super fiber. In the following, the application of relevant water-based resins in microfibers will be discussed in detail.

Super Fiber Has Air And Moisture Permeability

In essence, moisture permeability is a process of "adsorption diffusion transfer desorption". When there is a pressure difference between hydrophilic agent groups, water will be transferred from one side to the other, which is the process of moisture permeability. The water-based resin itself contains many hydrophilic groups, so it has moisture permeability. Moreover, water-based resins often contain many side groups, so there will be many micropores in the process of film formation, which is conducive to the generation of air permeability. Therefore, the air and moisture permeability of the film formed of the aqueous resin is relatively high. Therefore, the use of water-based resin in the process of producing super fiber synthetic leather is conducive to the permeability of super fiber.

It Is Beneficial To Realize Ecological And Environmental Protection Of Super Fiber Leather

Ecological synthetic leather should pay attention to environmental protection, and the following points should be done well: pay attention to clean production when making leather, and do not pollute the environment; Second, synthetic leather should be environmentally friendly, and its constituent substances should not be toxic or harmful; Third, the waste synthetic leather retains its biodegradability.

It Is Beneficial To Improve The Physical And Chemical Properties Of Super Fiber Leather

The physical and chemical properties of super fiber leather are often shown in the following three aspects: first, the abrasion resistance and scratch resistance of the film; The second is the low tenderness and softness of the skin film, that is, the same tactility as the dermis; The third is chemical corrosion resistance, that is, acid-base resistance and solvent resistance.
The solution of the abrasion and scratch resistance of the film depends on the physical properties of polymer materials. Based on this, the abrasion resistance and scratch resistance of the film can be improved as long as the appropriate polymer material is selected for the water-based resin. In addition, the softness of the water-based resin at low temperature is better, because there are many side groups in the production process of the water-based resin, which can enhance the elasticity of the film and make it more wear-resistant. Generally speaking, the use of water-based resins in microfibers greatly reduces its plastic sense, and it feels very soft and smooth, much like leather. In terms of chemical resistance, through the combination of multiple cross-linking and internal and external resultant cross-linking, the polymer material has realized a true network structure, and after film formation, its acid resistance, alkali resistance and solvent resistance have been greatly improved.
