Non-woven materials have been widely used in many fields such as medical and health care, filtration, prosthesis corrosion, clothing, agricultural protection, thermal insulation and sound insulation. In different fields of application, non-woven fabrics are required to have different properties, such as: antibacterial, antistatic, flame retardant, soft, anti-aging, hydrophilic, anti-mildew, etc. One or several properties of non-woven fabrics can be achieved by adding functional masterbatches. Below we give a brief introduction to the functional masterbatch.

(1) Flame Retardant Masterbatch

Non-woven fabrics are widely used in clothing, construction, automobile, decoration and other fields. It also puts forward higher requirements for its flame retardant performance. Adding flame retardant masterbatch during the preparation of the material can effectively improve the flame retardant performance of the product.

(2) Antibacterial masterbatch

In the human living environment, the microorganisms that cannot be seen by the naked eye are everywhere, and pathogenic bacteria such as bacteria and mold are the main factors affecting human health. . Therefore, the research and development of antibacterial functional materials has attracted extensive attention.

(3) Anti-aging masterbatch

Polymer materials may deteriorate in all stages of synthesis, storage, processing and final use, that is, the performance of the material is reduced, such as Yellowing, cracking on the surface of the product, loss of luster, reduction in impact strength, etc.; the fiber shows a decrease in mechanical properties such as tensile strength and elongation at break, thus affecting the normal use of the product. This phenomenon is a polymer material. of aging. 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 is conductive substances, such as: carbon black, carbon fiber, stainless steel microfilament, conductive polymer, etc. The other type is the type of adsorbing water molecules in the air. This type of antistatic agent is a polar compound with a hydrophilic hydrophilic group, and its hydrophilic group can adsorb the water molecules around the air to the material, so that 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, etc. Post-type antistatic agents are more commonly used to prepare antistatic masterbatches.

(5) Hydrophilic masterbatch

Polyolefin non-woven fabrics have poor hydrophilicity, and it is necessary to improve their hydrophilicity in some application fields, 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 feel, which limits its use as a thermal bonding fiber in non-woven fabrics. Users hope that the melting point of polypropylene fibers used can be lowered to 140°C or even below 130°C to adapt to the higher speed of thermal bonding production of non-woven fabrics and reduce energy consumption. If the melting point is too high, it is difficult to make high-strength and soft-touch nonwovens. Therefore, it is necessary to modify polypropylene fibers 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) Negative ion 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 the oxygen absorption and carbon dioxide Emissions can promote the body's metabolism, accelerate the redox process of the tissue, 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 a lot of inconvenience to our lives, such as: mildew on food and clothing.

With the widening application of non-woven materials and more and more functional requirements, it is both an opportunity and a challenge for functional masterbatch enterprises. 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 multifunctional masterbatch, such as: antibacterial, anti-mildew and deodorant masterbatch, hydrophilic soft masterbatch, negative ion far-infrared masterbatch, etc. Low dosage of high-performance masterbatch, such as: selection of high-performance nano-fillers, selection of appropriate dispersants to enhance the dispersibility of fillers, etc.
