Non-woven materials have been widely used in many fields such as medical and health, filtration, prosthesis corrosion, clothing, agricultural protection, thermal insulation and sound insulation. In applications in different fields, non-woven fabrics are required to have different properties, such as: antibacterial, antistatic, flame retardant, soft, anti-aging, hydrophilic, and mildew proof. One or several properties of non-woven fabrics can be realized by adding functional masterbatch. Below we briefly introduce the functional masterbatch.
(1) Flame retardant masterbatch
Non-woven fabrics are widely used in clothing, construction, automobiles, decoration and other fields. It also puts forward higher requirements for its flame retardant performance. Adding flame-retardant masterbatch in the preparation process of the material can effectively improve the flame-retardant performance of the product.
(2) Antibacterial masterbatch
In the human living environment, microorganisms that are invisible to the naked eye are ubiquitous, and pathogenic bacteria such as bacteria and molds are the main factors affecting human health. Therefore, the research and development of antibacterial functional materials has attracted widespread attention.
(3) Anti-aging masterbatch
Polymer materials may deteriorate in all stages of their synthesis, storage, processing and final use, that is, the performance of the material is reduced, such as yellowing, surface cracking of the product, loss of gloss, reduction of impact strength, etc.; fiber It is manifested as a decrease in mechanical properties such as tensile strength and elongation at break, thus affecting the normal use of products. This phenomenon is the aging of polymer materials. The aging of non-woven materials can generally be solved by choosing different anti-aging masterbatches according to different application fields.
(4) Antistatic masterbatch
Classification of antistatic agents: One type is conductive substances, such as: carbon black, carbon fiber, stainless steel microwire, conductive polymer, etc. The other type is to adsorb water molecules in the air. This type of antistatic agent is a polar compound with a hydrophilic hydrophilic group. The hydrophilic group can adsorb water molecules around the air to the material, making The surface resistivity of the material is reduced and static electricity is eliminated. Such as: glycerol monostearate, N,N-bis(2-hydroxyethyl) fatty amide and its ester mixture. Later antistatic agents are more commonly used to prepare antistatic masterbatches.
(5) Hydrophilic masterbatch
The hydrophilicity of polyolefin-based nonwoven materials is poor, and its hydrophilicity needs to be improved in some applications, such as baby diapers, facial masks, medical wound patches, etc.
(6) Flexible masterbatch
Conventional polypropylene avant-garde has a high thermal bonding temperature and soft hand feeling, so its status as a thermal bonding fiber in non-woven materials is restricted. The user wants to reduce the melting point of polypropylene fiber to 140°C or even below 130°C in order to adapt to the higher speed of nonwoven thermal bonding production and reduce energy consumption. If the melting point is too high, it is difficult to make nonwovens with high strength and soft touch. Therefore, it is necessary to modify the polypropylene fiber to improve its flexibility and reduce the thermal bonding temperature. By adding soft masterbatch in the preparation process, the melting point of the fiber can be effectively reduced, and the softness of polypropylene fiber can be improved.
(7) Anion Masterbatch
According to research, negative ions can regulate the excitation and inhibition of the central nervous system, improve the function of the cerebral cortex; increase oxygen absorption and carbon dioxide emissions, promote the body's metabolism, accelerate the redox process of tissues, and increase The body's immunity. Therefore, in recent years, negative ion products have become more and more popular.
(8) Anti-mold masterbatch
Mold brings many inconveniences to our lives, such as: mildew on food and clothing.
With the wider application of non-woven materials and more and more functional requirements, it is both an opportunity and a challenge for functional masterbatch companies. We must have keen insight, keep up with the pace of the market, and focus on the research and development of new products. The development trend of functional masterbatch: composite multi-functional masterbatch, such as: antibacterial, mold-proof and deodorizing masterbatch, hydrophilic soft masterbatch, negative ion far-infrared masterbatch, etc. Low-addition high-performance masterbatch, such as: selecting high-performance nano-fillers, selecting appropriate dispersants to enhance the dispersibility of the fillers, etc.
