Antibacterial materials

With the advancement of science and technology, the application of antibacterial materials has penetrated into all aspects of our lives, from medical equipment to household appliances, from personal care products to surface treatment of public spaces, antibacterial materials are silently playing their role.

PPM  closely follows the market development trend and continues to innovate, and has successfully integrated antibacterial properties into textiles. How did it achieve these technological breakthroughs? How are these innovative technologies applied in actual products? Let's explore the world of antibacterial materials of PPM together!

Q: What is antibacterial material?

A: Antibacterial materials, as the name suggests, refer to new functional materials that can inhibit or kill microorganisms such as bacteria, fungi, molds, etc. Its antibacterial essence lies in antibacterial agents. For example, antibacterial fiber refers to the use of physical or chemical methods to introduce antibacterial agents into the surface and interior of the fiber, so that it is not only not easy to fall off on the fiber, but also diffuses through the fiber interior in a balanced manner, so that it has a lasting antibacterial effect.

Q: What are the commonly used antibacterial agents?

A: At present, antibacterial agents are mainly divided into natural, organic, and inorganic types.

1. Natural antimicrobial agents

Natural antimicrobial agents are mainly extracts extracted from animals, plants and minerals, such as plant antimicrobial agents such as propolis and tea polyphenols, and animal antimicrobial agents such as chitosan and chitin. They have a killing effect on a variety of microorganisms, but the content of antimicrobial ingredients is low, the duration of efficacy is short, and there are few varieties. Due to the constraints of safety and production scale, it is difficult to use them in large quantities.

2. Organic antimicrobial agents

Organic antimicrobial agents destroy cell membranes through chemical reactions, denature proteins, and hinder metabolism, thereby playing a role in sterilization and mildew prevention. They mainly include phenols, thiazoles, quaternary ammonium salts, triazoles, pyridines, guanidines, and chlorine-containing antimicrobial agents. Such as commonly used disinfectants, disinfectant sprays, etc.

They have strong bactericidal power, good immediate effect, abundant sources, and strong ability to kill mold. However, with the emergence of drug-resistant pathogenic bacteria, and the poor heat stability of organic antimicrobial agents, they are easy to volatilize or hydrolyze, and the decomposition products and volatile components are easy to irritate the skin and eyes of animals, so they are unsafe to use and have a short life.

3. Inorganic antimicrobial agents

Inorganic antimicrobial agents are made of inorganic materials as carriers, and are compounded with transition metal ions such as silver, copper, zinc, oxides or photocatalytic materials such as TiO2 and ZrO2 with antimicrobial ability to make products with antimicrobial ability.

Compared with organic antimicrobial agents, inorganic antimicrobial agents have the characteristics of high sterilization rate, good safety, long-term effect, and no drug resistance against various viruses, bacteria and fungi. They have good heat stability and broad application prospects. They are generally valued by countries, especially Japan and European and American countries, and have gradually been widely used.

Q: What technological breakthroughs has PPM made in the field of antibacterial materials?

A: The addition of nano antibacterial powder increases the difficulty of spinning fine denier fibers. Therefore, in the fiber application of nano antibacterial powder, masterbatch and slurry technology are particularly important. Solving this problem will enable the application of nano antibacterial powder in the field of fine denier filament spinning. At the same time, they are essential to ensure the uniform dispersion of antibacterial agents in fibers and improve the performance of final products.

The antibacterial masterbatch and antibacterial slurry series products launched by PPM combine advanced material technology and innovative processes to bring new antibacterial solutions to the textile market.

Q: What products do you recommend?

A: 1. PET silver antibacterial masterbatch TA10113-A1

TA10113-A1 masterbatch uses inorganic composite silver-loaded antibacterial powder, which has stable and long-lasting chemical properties and meets the corresponding non-toxic detection requirements. The masterbatch has excellent spinning performance, and high-end products are represented by 75D/72f moisture-wicking DTY fiber and high color fastness fine denier color antibacterial fiber.

2. PET light-colored copper antibacterial masterbatch TA10452-A1

TA10452-A1 masterbatch is light in color and can release copper ions. Copper ions are a necessary element in the human body and are safe and harmless to the human body. They can achieve a broad-spectrum antibacterial effect by interfering with and destroying proteins in bacteria, and also have a good inhibitory effect on various fungi containing protein capsids.

3. PET zinc antibacterial masterbatch TA10041-A1

TA10041-A1 masterbatch uses a new type of high-efficiency nano zinc antibacterial material. The fiber spun by adding it in a certain proportion has good antibacterial and bactericidal effects, and is broad-spectrum, durable, non-toxic, and has no residue. Polyester raw materials are preferred as carriers, and advanced dispersion technology and manufacturing processes are used for production, with good spinnability.

4. PET graphene masterbatch TA10570-A1

TA10570-A1 masterbatch uses high-purity graphite material and does not contain heavy metals. It can be used in PET spun filament and staple fiber products. The fibers prepared are widely used in socks, underwear, outdoor warm clothing and other fields, with good antibacterial, far infrared and antistatic effects.

5. Zinc oxide antibacterial slurry

This product is made of high-purity active zinc oxide, special dispersants, and modifiers as raw materials, and is prepared by dispersion and grinding through a special process. It has a strong antibacterial effect on Escherichia coli, Staphylococcus aureus, and Candida albicans. The product can significantly improve the anti-ultraviolet and antibacterial effects of viscose fiber products; adding coatings can play anti-aging and antibacterial effects. These antibacterial functional products are carefully designed to adapt to different spinning conditions and application needs, ensuring that they provide efficient antibacterial performance without affecting the quality and comfort of textiles.

Q: What are the application scenarios of these antibacterial products?

A: Baolidi’s antibacterial functional products have a very wide range of applications. The following figure shows the application scenarios of common antibacterial textiles.
